5630 lamp beads is a SMD LED package specifications for the power products, the typical application power of 0.5W, size of 5.6 * 3.0 * 0.9mm. Domestic is usually called 5730 lamp beads, is actually the same thing , Pad completely common, features almost, 5630 is generally imported models, made in order to avoid the Samsung patent intention to change the size of the appearance of 5730.
5730 Lamp beads
1. 5630 bracket by the foreign patent restrictions, LED market in foreign applications more, and 5730 bracket because there is no patent restrictions, the domestic use of more, in fact, from the use of light on the effect of these two functions is the same 5730 SMD Is also based on stent 5630 stamping from the mold, so the appearance is the same.
5630 SMD 5730 patch is the difference between size, 5630 is the four legs, and its length between the two sides of the foot is 56mm, 5730 is the two legs, and its length between the legs on both sides 57mm.
3. 5630 SMD four relatively thinner foot, in the use of placement machine welding process sometimes because of tin is not enough, easy to solder joint, the defect rate is relatively high; 5730 chip pin on both sides were lengthened by 0.5 Mm (the same light-emitting surface), the welding process in the placement machine solder joint situation will decline compared to non-performing rate.
to sum up:
difference:
A, domestic called 5730, foreign called 5630;
B, the pin is not the same, 5730 is two feet, 5630 is four feet
the reason:
A, 5630 first produced in foreign countries, that is, South Korea's Samsung brand, and later in China also appeared in the same product that 5730, in order to form the gap, but also to non-infringement, only in the width increased 0.1MM, pin design feet, Named 5730.
B, the welding of the aluminum plate are shared, 5630 side of the two pins all attached to the pad, solder together with the 5730 side of a foot attached to the pad there is no difference, you can light up by the four Feet designed into two feet, can be considered the cost savings.
Different manufacturers of products vary widely, the price difference is large, the performance difference is also large.But the market most of the 5630 (5730) lamp beads have reached 45LM above, many have reached 50LM above, a few high-end products can reach more than 60LM, before 5630 actual On the first used in the field of backlight, but due to weak demand in the field of backlight, Korean manufacturers will be applied to the field of lighting, the price dropping all the way from 0.2 US dollars straight down to 0.07, 0.08 US dollars
