FAQ

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 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
LED package and LED SMD LED lamp, what is the difference? Will the release agent be used in that part?
They differ in form and belong to the SMDLED category. Encapsulation uses liquid silicone and epoxy resins as well. The patches are basically made of epoxy resin. Relatively speaking, the amount of liquid silica should be relatively large.
What is the difference between SMT LED packaging with silicone and epoxy resin transparent package? What is the market situation of these two types of packaging?
Epoxy resins turn yellow during short wave irradiation or long periods of high temperature, so they are very short lived when applied to high power lighting. That's why the LED lighting market is dominated by silica gel.But because of the low price of epoxy resin (silica gel and not at a level), and storage, use and processing is superior to silica gel, so the low power LED and some optical components still use epoxy resin package.
Such as title, please have welding patch LED lamp experience expert guidance, do not search from the Internet to the theoretical knowledge, thank you!
The welding speed and welding time because certainly give light foot heat, so the speed must be fast, tin wire and tip with better, while heating to tin iron head, avoid heating time is too long.
What, in what way do I shunt the LED?
LED lights are current driven, first of all, look at your LED's IF and VF values. How much power do you have?. Make sure the current is in line with the IF and the current limit can be achieved with resistors.
Led lamp and Led patch two what is the difference between ah, the feeling is a patch of long service life, whether or not? 5-10 meters pan area lighting lamp selection Everbright shaped or patch shape?
If you take a large area light, to see that the lighting requirements, functional lighting, or lighting atmosphere, or ordinary lighting, which is to be considered, the two optical (lens) can bring you the light angle planning.
How many volts is a single LED on the LED patch band?
The single LED on the LED patch band is around 3.3V.LED light emitting diode, which is a nonlinear component, its operating voltage (tube pressure drop) is also different: ordinary red LED about 1.5 V; ordinary green LED about 1.8 V; bright white LED up to 3.3 V or so.
