LED patch lamps are also common in our life, especially during the Spring Festival, we can see a large number of LED patch lamp belts wrapped around trees in the square. The so-called LED patch lamp belt is a device that assembles the lamps on the circuit board or hard board and is as long as the belt. The LED patch lamps are embedded on the lamp belt. LED chip lamps are widely used in outdoor lighting because of their good waterproof performance, convenient use of low-voltage DC power supply, various luminous colors and bright colors. These lights also make the festival atmosphere more grand and lively.

What are the models of LED patch beads?

5730 (5630) belongs to Samsung's high-power structure, each 0.5W, and the use current is 100-150mA

3030 is a high-power structure of Kerui. Each one is 1W, and the current used is 300-350ma. This structure also has 3W light beads (actually 2W, current 600mA)

3014 is a low-power, 0.1W each, and the use current is 30mA. Due to the use of bottom heat dissipation, it is higher than the conventional low-power current

The 2835 is a low-power one, each with 0.1W and 0.2W, and the use current is 30mA and 60mA. Due to the use of bottom heat dissipation, the heat dissipation area is larger than 3014, so the current can also be larger. Of course, the chip size should be considered. Some people also make it 0.3w and 0.5W

3528 belongs to conventional low power, each 0.06w, and the service current is within 20mA

The 5050 is a conventional low-power, each 0.06 * 3W, the use current is within 20 * 3mA, and there are three chips inside, so the current is three times that of the conventional

Now let's learn how to install the LED patch lamp.

How to install the LED patch lamp belt

The flexible LED light band is assembled with FPC as the assembly circuit board and patch LED, so that the thickness of the product is only the thickness of a coin and does not occupy space; General specifications include 750px long 18 LEDs, 24 LEDs, 1250px long 15 LEDs, 24 LEDs, 30 LEDs, etc. There are also 1500px, 2000px, etc. different users have different specifications. It can be cut at will or extended at will without affecting the luminescence. The FPC material is soft and can be bent, folded and wound arbitrarily. It can move and expand freely in three-dimensional space without breaking. It is suitable for irregular places and places with narrow space. Because it can be bent and wound arbitrarily, it is suitable for any combination of various patterns in advertising decoration.
