1.LED light source

LED lamp bead normally use 3528, others use 3014 and 5050. 3014 and 5050 low cost slightly less luminous efficiency, the key is its optical network design problems. 3528 high light efficiency outlets universal good.

2. power supply

There are 2 kinds of LED drive power, one is to use a constant current power supply, high efficiency of this mode, PF value up to 0.95, high cost performance; the second is to use a constant voltage and constant current power supply, stable performance, but low efficiency, high costs, the general use of this power is exported, the other party requires certification requirements shall have regulatory power. Family with constant current power supply is actually very safe, because users have access to the power source, and the body itself is using a safe low voltage.

3. reflective paper

Guide plate rear light reflection to improve light efficiency, typically RW250.
