5630 lamp bead is a kind of package specification for 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. Domestically, it is usually called 5730 lamp bead. It is actually the same thing. The pad is completely versatile and the characteristics are similar. The 5630 is generally an imported model. The domestically made 5730 is deliberately changed in order to avoid Samsung's patent.
one. The 5630 bracket is restricted by foreign patents and is widely used in the foreign LED market. The 5730 bracket has no patent restrictions and is used domestically. In fact, the two functions are the same from the light effect. The 5730 patch base is also based on the 5630 bracket stamping and opening, so the appearance is the same.

two. The 5630 patch differs from the 5730 patch in size. The 5630 is made of four solder fillets. The length between the solder fillets on both sides is 56 mm. The 5730 is a solder fillet. The length between the solder fillets on both sides is 57 mm.
three. The five soldering legs of the 5630 patch are relatively short and thin. In the process of soldering with the mounter, sometimes the solder is not enough, it is easy to solder, and the defect rate is relatively high; the 5730 chip has two sides extended by 0.5mm ( The luminous surface is unchanged. In the soldering process of the placement machine, the relative defect rate will decrease.
to sum up: difference:
A, domestic is called 5730, foreign is called 5630;
B, the pins are different, the 5730 is two feet, and the 5630 is the reason for four feet:
A, 5630 was first produced abroad, namely the South Korean Samsung brand. Later, the same product appeared in China, 5730. In order to form a gap, and for non-infringement, only 0.1MM was added in width, and the pin was designed as two legs. Name it 5730.
B. The soldered aluminum substrates are all shared. The two pins on one side of the 5630 are all attached to the pads. They are soldered together and can be lit without any difference between the 5730 and one foot on the pad. Designed by four feet into two feet, it can be regarded as a cost saving.
The products of different manufacturers vary greatly, the price difference is large, and the performance difference is also large. However, most of the 5,630 (5,730) lamp beads on the market have reached more than 45 LM, many have reached more than 50 LM, and a few high-end products can reach more than 60 LM. Previously, 5630 was actually used in the backlight field, but due to the lack of demand in the backlight field, Korean manufacturers Applying it to the field of lighting, the price has dropped all the way, from 0.2 US dollars to 0.07, 0.08 US dollars / PCS or so, the price is extremely high.
Before we talk about the difference, we should talk about the commonality between the two. First of all, they belong to the medium power lamp bead. Their power is defined as 0.5W, which is a kind of LED chip LED. The pads between them are universal, and there is no difference between them in strict sense. There is a slight difference between them in the details.
First, the difference in size: 5630 is 5.6mm (length) * 3.0mm (width) * 0.8mm (thickness) and the difference of 5730 lamp beads is 5.7mm (length) * 3.0mm (width) * 0.8mm (thickness).
Second, the difference between the pins: 5630 lamp beads are four pins and 5730 is two pins.
Third, Zener diode: The early 5630 was developed by Samsung. For example, Samsung's regular supply should be added with a Zener diode. The role of the Zener diode is to protect the role of the lamp bead, while the 5730 lamp is not on the one hand. Because as the technology continues to mature, the lamp bead process is becoming more and more mature, and the role of the Zener diode is not as great as it was then.
4. Thermoelectric separation type: The 5630 of Taiwan's Yiguang is a thermoelectric separation type. The thermoelectric separation type can accelerate heat dissipation and increase the life of the lamp bead. The 5730 lamp bead also has thermoelectric separation type but is relatively rare, while the 5730 lamp bead is currently Our company uses a large heat sink type, which can also accelerate the heat dissipation of the lamp beads.
In addition to these differences, they are common in performance and use, and some are different, don't worry that the aluminum substrate of the 5730 lamp bead can not be used on the 5630 lamp bead.
