Ultra Thin LED Flat Panel Light Good Quality Manufacturer 60x120cm Wire Hanging for School 40watt 6000K
PCB with buckle design , LED load
1. Buckle with buffer function, avoid LEDs collision by LGP,
prevent panel produce blue light when LGP expanded after long time lighting up.
2. LED load is about 35%, very low, to prolong life span.
595*595mm, 40W, 950mA, 90lm/w, use 204pcs LEDs,
0.5W 160mA 4014, 12 Serial, 17 Parelled
I =950mA/17=55.8mA, LED load is 55.8/160=35%
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.

Patented Design, LED strips fastened by buckle
1. Buckle with bufferring function, avoid LEDs collision by LGP, prevent panel showing blue light when LGP expands after long time lighting up.
2. LED strips fastened by buckle, tight and for direct heat dissipation through aluminum frame
LED strips pasted by adhesive tape
1. No protection of LEDs, LEDs easy to break during transportation or by expanded LGP when heat goes up, bad light uniformity.
2. LED strips sticked on to frame by double sided adhesive tape which influence heat dissipation
