Eulumdat Tools

Converting IES files to EULUMDAT: 4500 files in less than 2 minutes!

2012-01-15T11:25:00.001-08:00

To demonstrate the speed of large scale batch conversion I created a small demo video for EulumdatTools.

I recently added ready to install downloads for Windows, Linux and Mac OSX both 32 and 64 bit at the download site. 30 day free trial after registration!

A new version of EulumdatTools 0.9.7.v20111220 available

2011-12-20T14:20:00.001-08:00

A new version of EulumdatTools 0.9.7.v20111220 was published on December 20th at http://www.fold1.com/eulumdattools/. We again improved the batch conversion of IES files to EULUMDAT by fixing a nasty bug in the File/Import routine. This improved parser and conversion utility is also available free of charge at ies2eulumdat.appspot.com.

A new version of EulumdatTools 0.9.6.v20111129 available

2011-11-28T07:04:00.001-08:00

A new version of EulumdatTools 0.9.6.v20111029 was published on October 29th at http://www.fold1.com/eulumdattools/. We again improved the conversion of Type B photometry IES files to EULUMDAT to the existing conversion of Type C files. We also hardened the parser so more files with errors can be opened and displayed, so they can be corrected. We extended the hardcoded expiry date of this release to well in 2012. This improved parser and conversion utility is also available free of charge at ies2eulumdat.appspot.com.

New version of EulumdatTools 0.9.4.v20110729 available

2011-08-15T12:56:00.001-07:00

A new version of EulumdatTools 0.9.4.v20110729 was published today at http://www.fold1.com/eulumdattools/. We added the conversion of Type B photometry IES files to EULUMDAT to the existing conversion of Type C files. We also hardened the parser so more files with errors can be opened and displayed, so they can be corrected. We extended the hardcoded expiry date of this release to well in 2012.

Some background theory

The photometric intensity distribution in EULUMDAT files is similar to that a Type C IES file. The center of beam is straight down (or up) and there are vertical (IES: lateral) planes rotating around this central down axis. In each vertical (IES: lateral) plane there are a number of vertical angles. For more info see AGI32 website.

Trigonometric conversions

To determine the intensity at a pair of the C and γ angles, we need to interpolate at a corresponding pair of B and β angles. The corresponding B and β angles can be found using these formulas:

tan B = cos C * tan γ

sin β = sin C * sin γ

We added some extra logic to handle the determination of the right quadrant.

Interpolation used

Interpolation is done using standard lagrange over 3 planes and then over the 3 resulting points.

A new version of the free online IES to EULUMDAT Converter was published today at http://ies2eulumdat.appspot.com/.

After a discussion on LinkedIn lighting simulation group, I improved the character set recognition, so even if you do not use the "official" ASCII only encoding, your IES and EULUMDAT will still be converted correctly

The parser was improved to handle more case with funny whitespace characters, empty lines and other clutter that does not really follow the standard. Also IES files with versions before IESNA91 can be handled more or less. Instead of giving an error on incorrect format, the parser will now use the oldest format and try anyway. Not all fields will be filled in.

Visitors using Android or iPhone/iPad arriving at www.fold1.com will from now on be transferred to the mobile site where a special small form calculator called #luxCalc is available.

The initial screen shows a list of brands that have products available to design with.

After filling in room size...

...and lighting task details, you get a very short form proposal.

With this proposal you have the option either to email to the brands customer service desk in your country, or to place a phonecall to the local custiomer service desk (when available).
This last piece of functionality is not very stable yet, but it will be operational soon.

Technical details: the mobile site is built using HTML5, CSS, jQuery, and jqTouch.

New EulumdatTools 0.7.2.v20101210 released

2010-12-10T09:08:00.000-08:00

Today we released version 0.7.2.v20101210 of EulumdatTools, Eclipse based workbench for photometric files.

Version 0.7.2.v20101210 is available as an update to the standalone version EulumdatTools RCP and EulumdatTools plugin for use in the Eclipse IDE. How to upgrade: To upgrade select menu Help/Check for Updates and follow from there.

This update contains numerous improvements with regard to:

handling of files with some symmetry and non-equidistant C-planes in the photometry, that failed until now.
handling of different character sets: all the ISO-8859-x character sets are now recognized in addition to UTF-8. This is especially useful for those converting IES files of lamps produced by Chinese manufacturers. Also product names with accented characters as found in EULUMDAT files of European manufacturers are now handled properly.
Proper handling of changed product geometry specs in IES format LM-63-2002.
Some speed improvements in the conversion and validation routines.

Please note that the same improvements are deployed to the online IES-EULUMDAT and EULUMDAT-IES converters found at IES2EULUMDAT.

Online lighting design site www.fold1.com goes mobile!

2010-11-30T07:44:00.000-08:00

The last couple of years has seen a steady rise in the screen resolutions of the visitors to my online lighting calculation site Fast Online Lighting Design. In some months I see screens as large as 3200 x 1600 pixels!

Big screens keep getting bigger

Recently however a new group of very low screen resolutions has started appearing in the visitor logs. These must be smart phones like iPhone and Android and tablets, like iPad.

Small screens now mean smart phones visit you.

So I have adjusted the screen layout to work better on iPhone and iPad, mostly by setting a viewport and by making the page elements flow to adapt to portrait or landscape orientation. I also cleaned up the jvascript using the very capable jQuery library.

iPhone in landscape mode 480 x 320

iPad in portrait 768 x 1024

Next step is to make it touch aware: swiping the design alternatives from left to right and back and increasing and decreasing sizes and values using finger gestures rather than the standard web widgets.

Updating Eulumdat Tools finally works

I finally managed to create a version of Eulumdat Tools RCP where you can do check for updates and actually install the updates.
To get to this screen select menu Help then Check for Updates.

This means that checking for updates and actually doing them will take a lot less time. No need to reinstall the full package anymore, just upgrade the parts affected.

Make it automatic

You can make cheking for updates automatic by choosing Window/preferences (on Mac Eulmdat Tools RCP/Preferences) and choosing Instal/Update and then Automatic Updates and enabling them.Please note that you have to download complete RCP versions once more for omplete ZIP for Windows XP, Windows Vista/7.0, Linux GTK on x86, Max OSX (Snow Leopard 32 bit) or Max OSX (Snow Leopard 64 bit).

New version 0.6.7.v20100518 released

2010-05-18T05:52:00.000-07:00

Today I released a new version of Eulumdat Tools. It is available as Eclipse plugin or standalone RCP application for Windows XP, Windows Vista/7.0, Mac OSX 10.5 and Mac OSX 10.6 64 bit.

Complete RCP application for Linux

In addition to the commercial OS's I now also prepared a complete RCP application to run on Linux GTK, for example Ubuntu. This will widen the use of this application to more platforms. Photometric graphs are not yet shown on screen, but can be exported to file.

Import IES files Wizard

The IES import wizard was redesigned and can now select from one project and export to another.

Export E100 lux tables Wizard

The E100lux Table wizard was also redesigned and can now select from a project and export to anywhere in the file system.Select the folder or project to use as source.
Then select the reflectances to display in the table. The end result is text file containing e100lux tables:

New version 0.6.6.v20100416 released

2010-04-16T13:15:00.000-07:00

Today I released a new version of Eulumdat Tools. It is available as Eclipse plugin or standalone RCP application for Windows XP, Windows Vista/7.0, Mac OSX 10.5 and Mac OSX 10.6 64 bit.

Preliminary support for Absolute Photometry in EULUMDAT files

Since August 2009 the EULUMDAT standard was modified to allow Absolute Photometry as described here. The new rules boil down to the following changes:

Only one lampset is allowed
LORL is set to 100%
The number of lamps (line 26a) is set to a negative number

IES files with Absolute Photometry translate to the new format EULUMDAT files

Many LED light sources have photometric data provided as IES files. Eulumdat Tools allows easy conversion fo such files for use with softare such as Relux or Dialux.
EulumdatTools will also help manufacturers and importers of new energy saving light sources such as LED's to provide accurate and consistent photometric data.

Numerous smaller bugs in correctly displaying grahics for these lamps were also fixed

Thanks to Fanis Kavouropoulos and Linuz Backelin for helping track down and reporting these problems!

New version 0.6.3.v20100410 released

2010-04-09T15:29:00.000-07:00

Today I released a new version of Eulumdat Tools. It is available as Eclipse plugin or standalone RCP application for Windows XP, Windows Vista/7.0, Mac OSX 10.5 and Mac OSX 10.6 64 bit.

Improved IES file header parsing

IES files can contain many custom parameters, but these were not parsed but seen as errors.
Examples of problem lines:

IESNA:LM-63-1995
[TEST]
[DATE] 02-01
[MANUFAC] GE LIGHTING
[LAMPCAT] 30754
[LAMP] Q20MR11/SP15-FTC
[_CATEGORY] HALOGEN
[_SUBCATEGORY] MR11
[_BULB] MR11
[_RATED-CBCP] 1760
[_CANDELA-MULTIPLIER] 1
[_RATED-LUMENS]
[_RATED-LIFE] 3500
[_BEAM-ANGLE] 15
[_DETAILS] 
TILT=NONE
...

LInes starting with [_ will be ignored from now on, resulting in less editing being required in existing IES files.

Fixed div by zero error in rotation symmetric IES file parsing

Rotation symmetric IES files did not convert to EULUMDAT properly but resulted in an uncaught exception.
A proper error dialog was added and the cause of the div by zero fixed.
Also the offending files were added to the regression test suite.

Thank you Linuz Backelin for helping me track down and solve these two problems!

New version 0.6.3.v20100408 released

2010-04-08T05:32:00.000-07:00

Today I released a new version of Eulumdat Tools. It is available as Eclipse plugin or standalone RCP application for Windows XP, Windows Vista/7.0, Mac OSX 10.5 and Mac OSX 10.6 64 bit.

As I'm still in BETA stage I hardcoded an expiry date into the program, but forgot to update it. Very bad!
I'm also starting to handle PayPal payments, though the interface does not work very good yet.
Also EU VAT rules have changed so this requires a major effort to set up in terms of financial administration.

Many apologies again to my first customers. Please bear with me.

Please vote when you think IES to Eulumdat file conversion is a major item for Eulumdat Tools.
