FAQ

Patch LED beads can be bought in what place?
Many LED packaging plants do patch LED, you can find the relevant manufacturers to contact, or go to the local electronic components market according to your needs
How many volts is a single LED on the LED patch band?
3V or so, generally three, a group plus a resistor, power supply with 12V
Which is good for LED patch and LED bulb?
LED (light emitting diode) patch (package)LED patch (SMD) made by FPC circuit board, LED, high quality silica gel. The 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 - Entertainment decorative lighting lighting field.LED bulbA solid state semiconductor device that converts electric energy into visible light by means of LED (light-emitting diode), which converts electricity directly into light; LED = Large, Electronic, Display,;
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?
When making a batch of LED lights, the brightness values of various lights are in accordance with certain rules. Due to achieve a white balance, three RGB color brightness required by the ratio of 3:6:1, that is to say the blue light required brightness is very low.
Such as title, please have welding patch LED lamp experience expert guidance, do not search from the Internet to the theoretical knowledge, thank you!
Recommend to communicate with older employees, they will have a lot of welding experience
What is the principle used in SMD LED lamp, should pay attention to what the problem?
Pin forming, 1, LED pin molding must be completed before welding, bending angle must be more than 3mm of the gel to bend the stent. Pin over 2 times in the same place can not fold number, pin bent to 90 degrees, and then returned to the original position for 1 times; 2, pin forming must use fixture or by professional personnel to complete the first, pay attention to avoid the epoxy body caused by excessive internal wire fracture; 3, to ensure the distance between pin pin forming consistent with the circuit board; 4, when LED has good welding in the welding process or after, please don't bend light feet, to avoid damage to the lamp.
What is patch SMD-LED?
This really do not know how to answer you, like a sheet of the same type of solder paste used to operate, it can be said that the plug-in is not, it is patch it!
Patch LED features
The seismic resistance, high reliability, low operation cost system.It is easy to small, thin, lightweight, easy to shape without restrictions, made all kinds of application.
