Innolumis Batlamp

These luminaires have the same photometry, they differ but by luminous flux. All use amber LEDs, all are dimmable. They seem to be good for spacing 4 heights of shorter, with overhang amounting to 0.3 luminaire height at least, or 0.7 optimally. Or even with zero overhang, when meant for illuminating a sidewalk behind them a lot. A band width of 1.6 luminaire height is illuminated still quite uniformly, with maxima and minima about 4:1.

Curiously, luminous efficiency of luminaires is not the same: 31 W and 20 W lamps have 65 lm/W, the 14 W one has 73 lm/W and the 9 W lamp has nice 84 lm/W.

The luminaire is almost fully shielded, being a bit over the limit of 0 cd/klm (i.e., 0.49 cd/klm or less) just in several azimuths at 90 degrees from nadir (up to 0.7 cd/klm). Data from over 90 degrees are not reported, hopefully they are deep below this limit, so that the luminous opening is not visible at all from these directions.

Due to very large luminous intensity at 80 degrees from nadir, being 200 cd/klm in one azimuth, it is over the corresponding limit for IESNA Full-cutoff category, as it demands below 100 cd/klm there. The luminaire starts to obey this limit at 82.5 degrees. Evidently, for relative spacings below 6, the luminous intensity at 80 degrees should be reduced ten times at least, to reduce glare and improve visibility of the road or path.

An overview of ground illuminance distribution as produced by luminaires as offered by Innolumis. The file all_5.htm shows a photometric thumbnail overview for all of them when put 5 pole heights apart. all_5_70.htm differs by being sorted on maximum cd/klm about 70 degrees. all_single.htm shows thumbnails for luminaires being alone, non-rotated. Clicking on any thumbnail opens a larger image.

Specific illuminances are coded logarithmically by colours. Each colour comprises one decadic order, shades within the colour are 0.5 mag each (so five shade steps are 2.5 mag, what corresponds to ratio of 1:10).

illuminance scale

Values below the scale are illuminance / 1 lx. This is for (unrealistic) “unit” case that luminaires would have lamps producing 1 klm only, would be point-like and just 1 m over the terrain. A more realistic case would be lamps producing 10 klm each and being 10 m over the terrain: then the illuminances would be just 10× less.

The colour overview has been created using a Jan 2007 of ies2tab.
