Driver Design Inspection

 

---input voltage test: designed input voltage up to 304.7VAC, the output current very stable. In the nomial 277 VAC, PF value remains above 0.9. It works well when testing on the Tektronix oscilloscope and YOKOGAWA digital power meter

---peak and RMS voltage and current test: detect the points such as 100/230/277VAC, read all the peak/RMS/voltage/current, providing strong protection for design selection

---output load test: in order to guarantee stable working within the power supply outputs can be marked to eliminate possible result in abnormal movements for LED driver protection, we use chroma electronic load 63103A/63113A/6312A standard testing, LED driver quality has been improved

Driver Design- how to choose raw material

 

In order to reduce the failure rate of led driver and ensure product reliability, the failure rate of the raw material is only 0.03% in the standard lifetime. Therefore we set high requirements for the following key components:

---MOSFET, we choose higher configuration MOSFET, up to 10A/800V, current allowance 5-6 times, voltage allowance 2-3 times, reasonable control of the temperature rising

 

---Transformer, we use PQ2620 transformer which has a small leakage inductance, large AE area etc. stable current, reasonable control of the temperature rising, providing a strong guarantee to improve product quality

---Capacitor, in order to ensure the long lifespan of the power supply the capacitor should work 10,000 hours at 105°C. General assessment method of the lifespan of electrolytic capacitor is every 10°C less on its working temperature the lifetime of this capacitor is doubled.


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℃
