300x1200mm 1x4 26w Triac Dimmable LED Panel Light TUV-GS Certified 140 lm/w 3600lm 6000K aluminum white Office
The principle is to adjust each half wave conduction angle of alternating current to change the sinusoidal waveform and alter the effective value of AC current and thus to dim.
Why use PMMA LGP or PS LGP?
1. we use 4014(L40mm*W14mm) LEDs, then can match the light guide plate 3mm or 2.3mm perfectly. For luxury panel use 3mm PMMA before, and popular QT panel, use 2.3mm PMMA LGP now.
2. If using 2835(L35mm*W28mm) LEDs, then should use light guide plate 3mm at least and cost goes up
The LGP we use is silk printing by Japanese ink, Nagase brand, no drop after using 5years, panel uniformity is very good. If using normal PS material LGP, cheaper price, panel looks very vague and hazy when light up.
LGP (UV accelerated aging test, ISO 4892.3-2006 )
After UV test, panels using PS LGP turn yellowish,
Our panel using PMMA LGP still work well, good uniformity.
Panel use PS LGP, optical parameters like CCT and SDCM changed a lot, large lumen decay.
Potential risks, panel use PS LGP yellowing fast, especially when panel used in the room with sunshine, then lumen output will decrease and looks dark and ugly, non-uniform.

LGP (Temperature and humidity test)
At 40℃, in all the luminous zone, light emerge uniformly, No obvious visual difference
At 0℃, panel use PS light guide plate, in the middle of luminous zone, dark area appears
When temperature back to 2.31℃, dark area still exists in PS LGP; when back to 10℃, dark area disappears slowly
When temperature below 0℃, the panel use PS LGP appears dark area, bad user experience.
Comparison with others:
|Lighting mode and heat dissipation|
|Why us?||Why not others?|
1.4-side lighting, 4 pcs PCB with LEDs；
2.Panel Light uniformity more than 80%
3.Good heat dissipation, the aluminum frame can be touched by hand due to low temperature
4.Our panel maximum temperature is 36.7℃, minimum temperature is 23.7℃
1.2-side lighting, 2 pcs PCB with LEDs；
2.Panel Light uniformity about 70%, dim area
3.Bad heat dissipation,the aluminum framecan't be touched by hand due to high temperature
4.Other panel maximum temperature is 43.8℃ even higher, minimum temperature is 23.1℃
