CSbG-Luminaire TM helps preserve
Low energy use should not be the only attribute for a luminaire. The ecological and health impacts must be considered too. Other luminaires deliver various shades of white light. However white light, when used during the night, can disrupt our circadian rhythm and alters the nocturnal environment on which most life depends. The CSbG-Luminaire was designed to minimize these effects.
The CSbG-Luminaire has been developed with these attributes as guiding principles: spectrum, illumination level and extent of the illumination. They have been specifically designed to NOT provide the same character of intrusive outdoor lighting that most other luminaires produce.
The CSbG-Luminaire may not be suitable for some lighting situations. However they provide alternatives for more environmentally sensitive applications, and use significantly less electricity than many other luminaires.
For the image below, the luminaire was mounted 4.3 meters above the terrace and set for 3.5 watts.
The illumination at nadir was 1-lux. Sufficient illumination was provided over an area of more than 100 m2 with a uniformity of 3:1. It's bright enough, and after all, it's meant for users meet and enjoy the night, not ruin it.
Minimal glare and light trespass
Full (Sharp) Cut-Off optics with <1% in "glare zone"
Large illuminated area (3x1.5 mounting heights)
No blue light
Field-adjustable illumination level
Simple connection to 110vac or 220vac
Low power consumption
Flexible wall, post-top and tenon mounting hardware, however
|The light distribution and uniformity is compared with an unshielded 13-watt CFL lamp (left). The CSbG-Luminaire (right) is set for 14-watts giving 3 lux (3x that needed for pedestrian activity).||The effectiveness of our Sharp Cut-off shielding can be seen by the limited exposure to the trees. The optical design is evident from the extent and uniformity of the illumination and limited backlight.||The Eco-Light is set at 5 meters, which is suitable for pathway and safety lighting around building and garage entrances. And this provides subtle, non-intrusive illumination at outdoor events.|
These CSbG-Luminaires were mounted at 4.5 meters above the gravel road and spaced about 13 meters apart (2.8:1 pole spacing). The roadway illumination was about 3-lux (about 1/2 power setting). The uniformity is about 2:1, and increases to 3:1 at 3.5:1 pole spacing. The shadow band between the individual patterns is due to the sharp cut-off shielding. Notice the minimal backlight and the lack of glare from the luminaires. These attributes minimize light trespass and the ecological impact.
This installation uses the low-impact amber LEDs. We can also install relatively low-impact "warm white" LEDs (3000K - 15% blue light), or LEDs for about 2500K (7% blue) for "incandescent white".
We can modify the Luminaire's properties, and those of our other products, for different applications (on- and off-grid power and even hand-held units).
