1. Appearance：
Lamp beads bracket: Clearly we can see Samsung lamp bead has 4 pins , people call it 5630 which is popular for a time because of its 130lm/w , most of Chinese made lamp bead has 2 pins , people call it 5730 to avoid Samsung patent , because the optical efficiency of this type Lamp beads bracket is good , see as picture：

Non- Samsung lamp beads 5730
2. Components：
Samsung 5630 is a kind of lighting source mainly applied in television and flat panel backlighting , because there is high-voltage lines in TV and higher static electricity , .To overcome this problem , Samsung put a zener diode in every led to in order to improve the antistatic performance of lamp beads itself, the zener diode is see as picture：
5630 ZEMER DIODE
5730 NO ZENER DIODE
3. Chip：
Because most of Samsung lighting source are applied in television and flat panel backlighting, it needs the lamp beads have a much higher light efficiency .So the chips size that Samsung lamp beads use is 24*46MIL, besides , Samsung has its special electrode lines, see as pictures：

Non- Samsung lamp beads
The above 3 points can fully show Samsung lamp beads speciality , and also can easily distinguish whether it is Samsung lamp beads. However , the chips manufacturing of Samsung is from Taiwan Epistar, because of insufficient production capacity before 2013, 60% of chips buy from Epistar. After engaged in 10 years of lamp beads production , I always think Samsung is not better than Taiwan Epistar.(personal view) No matter Korea Samsung , Korea LG, neither of them has an easy time now (three Korea giant in lamp beads production) . The lighting efficiency of Chinese made lamp beads can be made 158lm/w(Cree’s lighting efficiency is 189lm/w) .The korea brand can win such a popularity, it owes to the effort of the whole korean. Which is just he problem I met in my business , I am pleased to share with you , Please forgive me if there is any imperfection.
