6 1. Lighting Database Overview The lighting database is stored in IES own format, and contains all the data about luminaires, lamps and lamp colours required for performing Radiance or FlucsPro calculations. You may edit any of the data, import it from or export it to manufacturers' data in CIBSE, EULUMDAT or IESNA format files, or perform database calculations to produce processed data such as light output ratios and utilisation factors from the raw polar data. The database can be used to add, delete, edit and store information about luminaires and lamps. The information from the database is used by the IES lighting applications (FlucsPro, Radiance, Template Manager, etc.). An extensive system database is provided but this can be supplemented with your own data. Photometric data may be entered into the program either interactively or by importing data from files in standard CIBSE, EULUMDAT or IESNA formats. The standard CIBSE type-1 and type-2 formats are used and are described in CIBSE TM14. For interactive input you describe the luminaire, the valid lamps for the luminaire, and polar-curve data for luminous intensities. Optionally, lightoutput ratios, spacing-to-height ratios, utilisation factors, and glare indices may be entered. For lamps the lamp description and, optionally, lamp-lumen maintenance-factor curves are specified. The database can calculate light-output ratios, spacing-to-height ratios, utilisation factors, glare data and aspect factors and can perform LG3 checks and BZ classifications for a luminaire, based on the polar-curve information. The results can be viewed on the screen and output as hard copy if you wish. The database is not an application that may be run directly, but instead is accessed via other applications such as LightPro, FlucsPro, Radiance and the Template Manager Access to the Lighting Database These commands are provided as buttons in the applications that use the database Select Light Fitting Command This command is available from several dialogue boxes in the applications that use the lighting database. The button is named Select. It allows you to select the luminaire, lamp, and colour from the database to use for the light fitting. The Select light fitting dialogue box is displayed. The selection is made from a list view (as used in the right-hand pane of Windows Explorer) that allows you to click any of the column headers to sort the data based on the values in that column. In addition you Page 6 of 54

7 may use filters to help when searching for items. Colour coded icons show the source of the data. Note you may also edit the database and perform database calculations from this dialogue box, but only when called from LightPro Review Command This command is available from several dialogue boxes in the applications that use the lighting database. The button is named Review. It allows you to review and edit the database. The Review database dialogue box is displayed. The five database tables are displayed, allowing you to review the items in the tables. In addition you may use filters to help when searching for items. Note you may also edit the database and perform database calculations from this dialogue box, but only when called from LightPro Path Command This command is available from several dialogue boxes in the applications that use the lighting database. The button is named Path. It allows you to set the list of custom folder paths where lighting database files are to be accessed. This allows you to access lighting data from different parts of your network in addition to the system data and the data within your own project folder. The Database path dialogue box will open allowing you to browse for and add folders, or to remove folders, from the list of paths Filters Command This command is available from several dialogue boxes in the applications that use the lighting database. The button is named Filters. It allows you to set the filters that affect what elements of the lighting database are to be displayed in the light fitting selection or lighting database review dialogue boxes (Note filters only affect the display - the program still has internal access to all of the data). The Filters dialogue box opens, allowing you to enter filters based on type and manufacturer categories, and on whether the data is from the system folder, the custom folders, or the local project folder. Page 7 of 54

8 2. Dialogue Boxes and Property Sheets The dialogue boxes and property sheets in the lighting database, and the items shown on them, are explained in this section Select Light Fitting Dialogue Box This dialogue box allows you to select a luminaire, lamp, and colour from three list views. When a luminaire is selected, the list of lamps is automatically updated to show lamps that are valid for the luminaire, and the polar curve is displayed. Similarly, when a lamp is selected, the list of colours is automatically updated to show colours that are valid for the lamp. The column headers may be clicked to sort on the property listed in that column. Menus are provided for database activities (database path and filters commands, saving the database, importing and exporting CIBSE, EULUMDAT or IESNA data, etc.) editing activities (add, properties, delete, database calculations) and changing the list view types.

16 2.3. Database Path Dialogue Box This dialogue box allows you to edit the list of custom paths (including UNC network paths such as "\\server\c\lighting\") that are searched for lighting database files. The system files (in the "lights" folder below the IES installation folder) and the project files (in the "lights" folder below your project folder) are loaded by default. The custom files are loaded according to the set of paths that you may edit here. You may make a particular set of paths always available by editing "autoexec.bat" to add a line beginning "set FLUCS=" followed by a list of folder paths, separated by semicolons, e.g.: set FLUCS="C:\Program Files\IES\apps\lights\osram";"C:\Program Files\IES\apps\lights\Philips" (This example would produce the set of paths shown in the diagram) Custom Database Paths List This list shows the list of custom database folder paths in effect Browse Allows you to browse for another folder to add to the database path Remove Allows you to remove the selected folder from the database path. Page 16 of 54

17 2.4. Filters Dialogue Box This dialogue box allows you to set the filters that are applied to the lighting database data for display purposes. It is useful if you have a large list of luminaires or lamps and wish to see a more relevant subset. Note filters do not affect the accessible data - only what is displayed in the various dialogue boxes Luminaire Use Categories List Lists the luminaire use categories from which none, one, or more may be selected. The luminaire category is a form of classification, so that particular types of luminaire can be reviewed more easily. See Luminaire use categories for a list of available categories. Page 17 of 54

18 Luminaire Manufacturers List The manufacturer name is the second form of luminaire classification so that the review procedure can be used more easily. The manufacturer is represented by a descriptive name. See Luminaire manufacturers for a list of available names, but any additional strings can be entered in the box below Other Luminaire Manufacturers Enter full or partial manufacturer names if they are not available in the list above. Each name should be entered on a new line by pressing the Return key Description Contains This Text Enter text here for a case-insensitive match with the text in the luminaire description. If you know a word in the description, this will make your search much more efficient Lamp Type Categories List Lists the lamp-type categories from which one may be selected.

20 2.6. Luminaire Property Sheet This property sheet is for editing the properties of a luminaire. It has five pages: General page Valid lamps page Polar curves page Utilisation factors page Uncorrected glare indices page Luminaire General Page This page allows you to enter the general details required for the luminaire, including its ID and title, type, dimensions, light output ratios and type and manufacturer categories Luminaire ID Enter a unique ID. Page 20 of 54

21 Luminaire is Still Manufactured? Select this box if the item is still manufactured, i.e. still available for use Title Enter a title for this luminaire Type Options Select the type of luminaire: Point source option - Select this option to specify that the luminaire may be treated as a point source - i.e. has negligible area of light source. Uplighter option - Select this option to specify that the luminaire may be treated as an uplighter - i.e. most of the light output is upwards. Linear option - Select this option to specify that the luminaire may be treated as a linear luminaire - i.e. has an extended area of light source Standard Length The luminaire standard length is the length used for photometry. It is the base for glare corrections and has a correction factor for polar curves and a utilisation factor of 1.0 and a glare-indices conversion factor of Width The luminaire width is used to calculate the default luminous base area, which is used in the detailed glare calculations Height The luminaire height is used to calculate the default luminaire side and end areas which are used in the detailed glare calculations Upward Light Output Ratio The ratio of the total light output of a luminaire above the horizontal under stated practical conditions to that of the lamp or lamps under reference conditions Downward Light Output Ratio The ratio of the total light output of a luminaire below the horizontal under stated practical conditions to that of the lamp or lamps under reference conditions Maximum Spacing/Height Ratio This ratio describes the distance between luminaire centres in relation to their height above the working plane. The maximum spacing-to-height value should not be exceeded if the uniformity of illuminance is to be acceptable for general lighting Transverse Spacing/Height Ratio The transverse spacing-to-height ratio ensures that spacing in the transverse direction provides the illuminance uniformity Lamps per Luminaire Enter the number of lamps mounted within the luminaire. Page 21 of 54

22 Luminaire Use Categories List Lists the luminaire use categories from which none, one, or more may be selected. The luminaire category is a form of classification, so that particular types of luminaire can be reviewed more easily. See Luminaire use categories for a list of available categories Luminaire Manufacturer Enter a 2-character manufacturer reference if it is not available in the list below Luminaire Manufacturers List The manufacturer name is the second form of luminaire classification so that the review procedure can be used more easily. The manufacturer is represented by a descriptive name. See Luminaire manufacturers for a list of available names, but any other name can be entered in the box above Luminaire Valid Lamp Page This page allows you to edit the list of valid lamps for the luminaire. This is basically a list of entries in the valid lamps table, which contains cross-references to the luminaire and lamps tables, with some additional data. When you add or edit a valid Page 22 of 54

23 lamp the Valid lamp page appears which allows you to select a lamp from the lamps table. You may also delete any existing valid lamp. Any number of valid lamps may be specified for each luminaire. For a linear fluorescent fitting for instance you may wish to define the various lengths, such as 1200, 1500 and Alternatively, a high-bay fitting may be capable of taking a SON lamp or a MBF lamp. For each valid lamp a number of other relevant pieces of data are required, such as the length and wattage, which will depend upon the lamp being used Luminaire ID Shows the luminaire ID. This is not editable here List of Valid Lamps This displays the list of valid lamps for the luminaire Add New Button Adds a new colour for the lamp and displays its property sheet Properties Button Displays the property sheet for the selected colour. Page 23 of 54

24 Luminaire Polar Page This page allows you to edit the polar curve data for the luminaire. The polar curve data is presented in a grid and displayed in the graphic area. Angles may be added, inserted, edited or deleted from the context menu that appears when you click the right mouse button in the shaded area of the grid. The design attitude and photometry type may also be edited. Individual intensity values may be edited by selecting an intensity value and clicking the right mouse button in the non-shaded area of the grid. A range of intensity values may be selected and then edited by pressing the Edit button. Polar-curve data may be measured using the C-gamma (C-γ) system, the Horizontal Vertical (H-V) system or the IESNA Type C system (see CIBSE Technical Memorandum 14 and IESNA-LM63 for further information on these systems). The C-gamma system allows both point and linear sources to be defined in the same manner. A maximum of 72 C (or H) angles and 55 gamma (or V) angles can be defined when the data is entered interactively. For example, for a symmetrical luminaire this allows the C angles to be in steps of 15 degrees from 0 to 180, and the gamma angles to Page 24 of 54

25 be in steps of 5 degrees from 0 to 180. Such a large number of polar points will allow almost any type of polar curve to be defined, yet not all values need to be entered when specifying simple symmetrical polar curves. You can define the actual angles; in this way a large number of points can be specified where the curve is rapidly changing and fewer where the curve is changing little. The luminous intensities should all be expressed in terms of candelas per thousand lumens. Note that if the data are entered from a standard format file using the database facility, 72 C angles and 55 gamma angles can be defined Data is Valid? Select this box if the polar data is valid for use in calculations Design Attitude The design attitude is the angle at which the luminaire is designed to operate. For normal indoor luminaires it is zero Edit button If a range of intensities are selected this button will allow you to enter a new value to apply to the whole range. So, for instance, you may select the whole row at gamma=0 and set them to the same value in one go Photometry Options Select the photometry that was used to create this data: C-gamma option - Most interior luminaires are photometered using the C-gamma system. Horizontal-vertical option - Floodlights (due to their intensity distribution) are usually photometered using the horizontal-vertical system. IESNA Type C option similar to H-V but differing in the pole direction Show Selected Column Only Check Box This check box allows you to turn on or off the display of the selected column (i.e. one C (or Horizontal) angle) of polar intensity values. This is useful if you have defined several C (or Horizontal) angles and want to see the data for individual angles Polar Data Grid Displays the numeric values of the polar data. C (or Horizontal) angles are listed along rows 1 and 2. Gamma (or Vertical) angles are listed down columns 1 and 2. The body of the grid shows the intensities for the relevant pair of angles (in candelas/1000 lumen). The right mouse button may be clicked in any of these three areas to edit the angles or intensity values Angles Menu Page 25 of 54

26 This menu is available when you right-click in grid row 1 or column 1, and it allows you to select an option for editing angles for the polar curve: Edit angle - Select this option to edit the selected angle. Insert angle - Select this option to insert a new angle at the currently selected position in the list. Add angle - Select this option to add a new angle at the end of the list. Remove angle - Select this option to remove the selected angle from the list. Visualise use a window like the Model Viewer to see the photometric web generated by the polar curves Polar Curve Display Displays the polar curves graphically, for confirmation. If the Show selected column only check box is selected, it displays only the column that has the currently selected grid cell: Double-clicking on this plot has the same effect as using the Angles > Visualise menu option. Page 26 of 54

27 Luminaire Utilisation Factor Page Allows you to edit the list of utilisation factors at standard room indices for the luminaire. Individual values may be edited using the Utilisation factor dialogue box. Note it is recommended that you use the database calculations to calculate these values rather than entering them manually here. The utilisation factor is the proportion of luminous flux emitted by the lamps that reaches the working plane. The factors should be for zero reflectances for the nominal spacing-to-height ratio at the standard room indices, as described in CIBSE TM5. Nine values should be entered in ascending order, to correspond to room indices of 0.75, 1.0, 1.25, 1.5, 2.0, 2.5, 3.0, 4.0, and Data is Valid? Select this box if the UF data is valid for use in calculations Utilisation Factor List Displays the list of utilisation factors for the different room indices. Double-click a row to edit it, or select a row and press the Edit button. Page 27 of 54

28 Edit Button Edits the selected row Utilisation Factor Dialogue Box Allows you to edit an individual utilisation factor for the luminaire Uncorrected Glare Indices Page This page allows you to edit the uncorrected crosswise and endwise glare indices at the standard room reflectances. Individual rows may be edited using the Glare dialogue box. Note it is recommended that you use the database calculations to calculate these values rather than entering them manually here. The indices should be entered for each of the nineteen standard-room dimensions, as described in CIBSE TM10. They should be for ceiling, wall and floor reflectances of 70%, 50% Page 28 of 54

29 and 20% respectively Data is Valid? Select this box if the glare data is valid for use in calculations Glare Data List Lists the glare indices for each set of standard room dimensions.

This is used as a base for the default user name User Name Enter your user name or accept the default suggested for you. Page 38 of 54

39 2.13. Database Calculations Dialogue Box This dialogue box appears when you select the "Database" option from the context menu when a luminaire is selected and then select "Calculations". The buttons show the available calculations: Light Output Ratios and Spacing/Height Ratios Button This option is used to calculate the upward and downward light-output ratios (LORs) and the maximum, maximum transverse, and nominal spacing-to-height ratios (SHRs) for the given luminaire. The calculation method is based on the procedures in CIBSE TM5. Results are stored with the luminaire Utilisation Factors Button This option calculates the standard utilisation factors for the nine given room indices (0.75 to 5) following the procedures given in CIBSE TM5. Results are stored with the luminaire Glare Data Button The standard uncorrected glare indices for the nineteen standard room sizes of X and Y for reflection factors of 70 (ceiling), 50 (walls) and 20 (floor) are calculated. Page 39 of 54

40 For each room size, values for endwise and crosswise viewing are given based on the procedures in CIBSE TM10. Results are stored with the luminaire Aspect Factors Button The parallel and perpendicular aspect factors for the luminaire are calculated at 5 degree intervals from 0 to 90 degrees BZ Classification Button Not available at present This option calculates the British Zonal (BZ) classification for the luminaire within the nine standard room indices (0.75 to 5) LG3 Checks Button This option checks that the luminaire selected meets the criterion for the design of downlighting, from the CIBSE Lighting Guide LG3, 'Areas for Visual Display Terminals', as amended in You will be asked to select the luminance limit for the luminaire and the limit elevation angle above which the luminance limit must not be exceeded More Detail Check Box Select this option to get more control over, and more detailed output from, the calculations. Allows you to turn on or off the parts of the calculations which request more input data from you or give more detailed output Print Output Button Allows you to print the messages from the calculations Clear Output Button Allows you to clear the messages from the calculations Results Area Displays the results of the database calculations.

41 2.14. Batch Calculations Dialogue Box This gives you important information about what the batch calculations will perform. After the calculations the results are displayed in a Results dialogue box. Page 41 of 54

42 2.15. Batch Edits Dialogue Box This allows you to override selected data on a global basis for all the selected luminaires Set Type Check Box Select this if you want to set the type for all the selected luminaires, and then select an option below: Point source option - select this option to specify that the luminaire may be treated as a point source - i.e. has negligible area of light source. Uplighter option - select this option to specify that the luminaire may be treated as an uplighter, i.e. most of the light output is upwards. Linear option - select this option to specify that the luminaire may be treated as a linear luminaire, i.e. has an extended area of light source Set Use Category Check Box Select this if you want to set the use category for all the selected luminaires, and then select a use category below Luminaire Use Categories List Lists the luminaire use categories from which none, one, or more may be selected. The luminaire category is a form of classification, so that particular types of luminaire can be reviewed more easily. See Luminaire use categories for a list of available categories Set Manufacturer Check Box Select this if you want to set the manufacturer for all the selected luminaires, and then enter or select a manufacturer below. Page 42 of 54

43 Luminaire Manufacturer Enter a manufacturer name if it is not available in the list below Luminaire Manufacturers List The manufacturer name is the second form of luminaire classification so that the review procedure can be used more easily. The manufacturer is represented by a descriptive name. See Luminaire manufacturers for a list of available names, but any additional name can be entered in the box above Import Dialogue Box This property sheet is displayed when you import from external photometric data. It has one or two pages, depending on which format you are importing from: General import page IESNA import page See to view the specification of the EULUMDAT format provided by HELIOS32. The IESNA and CIBSE formats are available from the respective bodies. Page 43 of 54

44 General Import Page This property page allows you to control the process of importing luminaire data from external file formats. The options allow you control over what happens if the luminaire name already exists, or if the lamp name does NOT already exist If the ID and Description Both Match an Existing Luminaire Option Select the action you wish to take in this circumstance: Overwrite option - overwrite the luminaire if it already exists. Overwrite extra data option if this option is selected, the polar data of the existing luminaire will be overwritten. Prompt for unique ID option - ask for a new luminaire ID if it already exists. Automatically generate unique ID option - automatically generate a new unique luminaire ID if it already exists. This works by appending numbers to the ID, starting with "0" and increasing until a unique ID is found (i.e. does not already exist in the database). It is the safest option, because a new ID will always be created. The downside of this is that the same luminaire may be stored in the database under more than one ID. Skip luminaire option if this option is selected, the luminaire data will not be overwritten. The import file will continue to be read until another luminaire is found Page 44 of 54

45 or the file has no more luminaire data If it is Assumed to be a New Lamp Option Select the action you wish to take in this circumstance: Add valid lamp AND lamp option - if this option is selected, the relevant valid lamp will be created in the database, and ALSO the relevant lamp will be created. Add valid lamp ONLY option - if this option is selected, the relevant valid lamp will be created in the database, but the relevant lamp will NOT be created IESNA Import Page This property page only appears when importing IESNA format luminaire data (Note IESNA = Illuminating Engineering Society of North America, NOT Integrated Environmental Solutions). The page is fairly complex because of the degree of flexibility the IESNA format allows the manufacturers or photometric testers who produce the files. Some manufacturers use particular lines within the first 9 lines of the file to encode the luminaire and lamp catalogue reference and titles. Some use the keywords for encoding this information. Finally, some do not encode the information within the file at all, but instead encode it into the file NAME, using their own non-standard formats. Page 45 of 54

46 In addition, there may be one luminaire per file or multiple luminaires per file Method for Obtaining the Luminaire and Lamp ID s and Descriptions Option Select the method that will be used to obtain these items from the file: Decode option - select this option if the luminaire and lamp ID's are encoded in the filename. If this option is selected you must enter data in the next two fields also: Delimiter - enter the character which the manufacturer or photometric tester used to separate the luminaire and lamp ID's encoded into the file name; e.g. for the ERCO file "ERCO_12408+T16_54W.IES", the luminaire is "12408", the lamp is "T16_54W", and the delimiter is "+". Ignore text - enter text which the manufacturer or photometric tester added to the file name which must be ignored; e.g. for the ERCO file "ERCO_12408+T16_54W.IES", the luminaire is "12408", the lamp is "T16_54W", and the ignore text is "ERCO_". Use line 2/3/4 option - select this option if the file contains the luminaire ID on line 2, the luminaire description on line 3, and the lamp description on line 4. Use line 3/2/4 option - select this option if the file contains the luminaire ID on line 3, the luminaire description on line 2, and the lamp description on line 4. Keywords option - select this option if the luminaire and lamp ID's and descriptions are encoded in the file using keywords such as "[LUMCAT]ABCD" LG3 Dialogue Box This dialogue box is displayed when you select the LG3 calculation. The CIBSE Lighting Guide LG3:1996 "The visual environment for display screen use" specifies a test for assessing the potential for glare from a luminaire. A luminance limit is specified and a limiting angle to the vertical above which the luminance is checked. If the luminaire's luminance is below the limit at all angles below the limiting angle then the LG3 check is satisfactory. Page 46 of 54

47 Luminance Limit Select the luminance limit to be checked above the specified limiting angle Limiting Angle Select the angle to the vertical above which to check the luminance limit Import Summary Dialogue Box This appears after importing photometric data. You should heed the warnings given, as the same categories must be applied to the whole batch of imports. Also bear in mind that the import process depends on the quality of the photometric data. Page 47 of 54

48 2.19. Database Summary Dialogue Box This dialogue box gives you a brief summary of the location and contents of the lighting database, using a Results dialogue box Results Dialogue Box This is a general purpose dialogue box that is used in different situations where a list of results is required. Page 48 of 54

49 Clear Button Allows you to clear the summary Print Button Allows you to print the summary Save Button Allows you to save the summary to file Numeric Entry Dialogue Box This dialogue box is used when the program requires you to enter any numeric value apart from the usual data entered via dialogue boxes or property pages Prompt Displays the text describing the data input that is required Numeric Value Enter the required numeric value here Text Entry Dialogue Box This dialogue box is used when the program requires you to enter any text value apart from the usual data entered via dialogue boxes or property pages. Page 49 of 54

50 Prompt Displays the text describing the data input that is required Text Value Enter the required text value here Visualisation of Photometric Web This displays the photometric web generated by the polar curve data. It is useful for examining complex webs and for checking your edits. It is obtained by using the Visualise menu option, or by double-clicking the polar curve plot, on the Select light fitting dialogue box or on the Luminaire polar curve page. It uses the same 3d viewer control as the Model Viewer, so the buttons for navigation, movie-making etc. are the same. The only difference is that the ground plane is irrelevant here, so it is disabled. The x and y axes and the bounding rectangle of the luminaire are also displayed. Page 50 of 54
