FAQ

How do led patches measure good or bad?
Use the two stage tube test of the multimeter, the red pen is connected, and the black pen is negative. If there is a bee, the sound is bad, and if the light is bright, it is good
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.
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!
What is patch LED?
Patch LED refers to surface mount LED.The LED is separated from the PCB board in the form of inline and surface mount. Piranha, 3mm lights, and 5mm lights are all pins. While most high-power LED is surface mount, that is, patches. Small power LED also has the form of surface mount such as PLCC-2 and PLCC-4.
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.
What is the difference in performance between the LED plug-in and the LED patch?
No difference, because the core of the two is the same, are diode PN junction, but no packaging, the production process is a little different
What, in what way do I shunt the LED?
In series, the voltage is 20 times the rated voltage, in parallel, the voltage is rated voltage, but in tandem, a LED is broken, it is not bright, so it is recommended not to use it.
LED patch lamp band, how to calculate how many watts a meter, such as 3528-60 beads is how much?
3528 single lamp is 0.06W 0.06*60 lamp =3.6W 3528-60 bead is 3.6W/ meters
