5630 lamp bead is a packaging specification of SMD LED. It is a medium-power product. The typical application power is 0.5W and the size is 5.6*3.0*0.9mm. In China, it is usually called 5730 lamp bead. , is actually the same thing. The pads are completely universal and the characteristics are similar. The 5630 is generally an imported model. The domestic model deliberately changed the appearance size to avoid Samsung's patent and got the 5730.
5730 lamp beads
1. The 5630 bracket is restricted by foreign patents and is widely used in foreign LED markets. However, the 5730 bracket is mostly used in China because it has no patent restrictions. In fact, the two functions are the same in terms of light efficiency. The 5730 chip is actually stamped and molded based on the 5630 bracket, so the appearance is the same.
2. The difference between the 5630 patch and the 5730 patch is the size specification. The 5630 has four solder legs, and the length between the solder legs on both sides is 56mm. The 5730 has two solder legs, and the length between the solder legs on both sides is 57mm.
3. The four solder pins of the 5630 patch are relatively short and thin. During the welding process using the patch machine, sometimes the soldering is easy due to insufficient tin adhesion, and the defective rate is relatively high; the 5730 patch pins are lengthened by 0.5mm on both sides ( The light-emitting surface remains unchanged), and the relative defective rate of false soldering during the welding process of the placement machine will decrease.
Summary:
Differences:
A, it is called 5730 in China and 5630 abroad;
B, the pins are different, 5730 has two legs, 5630 has four legs
Reason:
A, 5630 was first produced abroad, namely the Korean Samsung brand, and later the same product appeared in China. 5730, in order to create a gap and avoid infringement, only 0.1MM was added to the width, and the pins were designed to be two-pin, named 5730.
B, the welded aluminum substrates are all for general use. The two pins on one side of 5630 are all attached to the pad, soldered together, and one pin on each side of 5730 is attached to the pad. There is no difference, both can be lit. Designing from four legs to two legs can also be regarded as a cost saving.
The products of different manufacturers vary greatly, with large price differences and large performance differences. However, most of the 5630 (5730) lamp beads currently on the market are above 45LM, many have reached above 50LM, and a few high-end products can reach above 60LM. In the past, 5630 was actually used in the backlight field, but due to the sluggish demand in the backlight field, Korean manufacturers Applying it to the lighting field, the price has dropped all the way, from 0.2 US dollars to about 0.07 or 0.08 US dollars/PCS, which is extremely cost-effective.
