FAQ

Patch LED beads can be bought in what place?

If you don't want to constantly change with it, suggest you go to OSRAM, Nichia, Corey, Taiwan Tongjia enterprise authorized agency purchase.

What is patch LED?

LED lights, a common model, has 34654635285050 piranha.The most common assembly of lights and PCB boards is the DIP, that is, dual in line and SMT surface mount technology two.The 346546 is the LED with two positive and negative pins, which are inserted into the PCB board after cutting the foot;3528 and 5050 are a cube with 3 LED lights inside, known as the "three in one" LED lamp. It has no pin underneath, but has a metal patch that can be passed through the reflow soldering machine through the solder to the PCB board.General indoor LED screen with more patches, outdoor screen with more pins.

What is the difference between patch LED beads and LED beads: General

A pin of the lamp, and outside a resin cap, because the reason LED beads can spotlight cap;There is no pin on the patch and there is no resin cap outside. Because of the lack of cap, the LED patch can not be concentrated.LED patch lamp is made of FPC circuit board, LED lamp and high quality silica gel sleeve. Waterproof performance, using low voltage DC power supply is safe and convenient, light colors, bright colors; outdoor use can be anti UV aging, yellowing, high temperature resistance and other advantages, the products are widely used in building lights, decorative lighting, advertising and entertainment quasi decorative lighting lighting field.

Production of a number of substrates, the use of SMD LED lights, red lights and green lights are not bad, blue lights appear mass dark, do not know why? Is the LED blue light material easy to use dark?

The pressure drop of the blue light is greater than that of the red light and the green light. If the series connection is the same as that of the green light and red light, the current limiting resistor will tend to dim

Such as title, please have welding patch LED lamp experience expert guidance, do not search from the Internet to the theoretical knowledge, thank you!

When soldering, the temperature is best to be lower, and the average welding temperature is about 360. That's enough, because the melting temperature of the tin wire is about 220 degrees, so if it is allowed, the temperature can be reduced as low as possible.

LED patches have several ways of welding. Which ones can be reflow? What can be done by eutectic welding? Is the welding of viscose and lens material is required?

Chip and stent welding methods are: eutectic welding, silver glue fixed, resin insulation and fixed silicone rubber insulation fixedWelding beads: reflow soldering, hot plate welding and manual soldering.

What does patch LED light mean?

The patch may be said, adding that the patch board PCB light source, light source lamp light source generally refers to, patch may refer to the combination of PCB plate and two lens beads.

Patch LED features

Without heating time, lighting is faster than general light (about 3 ~ 400ns).The electro optic conversion efficiency is high, the power consumption is small, and the energy consumption is about 1/3 ~ 1/20 than that of the bulb.
