LED Driver
 
How to choose a driver?
---make sure that the required load is constant current mode or constant voltage mode
---choose the appropriate wattage according to the load including adequate safety margin
---confirm whether PFC function is needed
---check the working environment such as grid voltage, temperature and humidity, etc
---confirm what safety certificate to comply with
---if and which type of dimming is needed
---make sure the key components are qualified
---confirm if the manufacturer is formal

LED
Why us?Why not others?

1.Supplied by Kinglight - Top 3 LED packaging manufacturer in China,
equipped with world-advanced 800 LED packaging auto lines, high quality chip
2. 99.99% golden wire in led chip and copper holder to make the LEDs, gold has the best ductility, won't break when heat changes
3. Long lifespan, slow light decay, LM 80 approved
4. Our LED load is about 37%, very low, to prolong life span, lumen maintenance is high over time
for example, for panel 40W, 1000mA,
---use 204pcs 4014 SMD LEDs,0.5w/LED
If=160mA (forward current).12 Serial, 17 Parallel, 
I =1000mA/17=58.8mA,
LED working load is 58.8/160=37%

1. Supplied by small LED packaging factory or big factory for low end market who use cheap chips which are not famous brand
2. Use alloy wire and iron holder to make LEDs, alloy has poor ductility, may get broken when heat changes, which makes LED defective
3. Short lifespan, fast light decay.
4. LED load is 63~104%, fast lumen decay.
for example, for panel 40w, 1000mA
---use 120pcs 2835 LEDs, 0.5w/LED
If=160mA (forward current), 12 Serial, 10 Parallel
I=1000mA/10=100mA
LED working load=100/160=63%
---or use 192pcs 2835 LEDs 0.2w/LED
If=60mA (forward current), 12 serial16 parallel
I=1000mA/16=62.5mA,
LED working load is 62.5/60=104%

Remark: The way to test if the LEDs use copper holder or iron holder :
Use magnet, the LEDs which are on magnet use iron holder.
