FAQ

The ten patch LED lights are connected in parallel. The rated power is 5 watts. How much voltage do you need?
The voltage needs to be determined according to the product specification, usually 3.1 - 3.5V
Such as title, please have welding patch LED lamp experience expert guidance, do not search from the Internet to the theoretical knowledge, thank you!
First of all, welding LED and other electronic products with line electrostatic ring, to prevent static light.When welding the patch LED lamp, first add the tin on the pad of the lamp board, then clamp the LED patch lamp with tweezers. Then, the soldering iron will melt the tin of the solder plate of your lamp board, and then push the LED lamp onto the pad with tweezers. The whole welding process should not exceed 5 seconds, otherwise it will burn the lamp easily.
SMD LED lamp working voltage?
Voltage range of white LED lamp: 3.0-3.4VThe pressure drop of the red LED is 2.0--2.2VThe yellow light emitting diode has a pressure drop of 1.8 - 2.0VThe green light emitting diode has a pressure drop of 3 - 3.2VThe blue light emitting diode has a pressure drop of 3.0-3.4VSMD voltage is basically the same as double lead line. Current is generally 20~60mA, and some work current can exceed 100mA.
How to detect LED SMD beads
The output voltage of the digital clock diode file is not high, generally below 2.5V, so the measurement of LED lamp does not work, the best way is to external electrical measurement. If there are a lot of beads to measure it, can take a constant current power measurement.
0603,0805,1206,3020,3528,5050,355 what is the current and voltage of these patch LED? Please give advice!
SMD LED specification:(1) metal stent type: 0402, 0603, 0805, 1206, 3mm, 5mm, 6mm, 8mm, 10mm and so on.(2) metal support (commonly known as small butterfly) type: 2mm, 3mm and so on.(3) TOP LED (white shell) type: 1208 (30*20), 1311 (35*28), 1312 (35*32), 2220 (55*50) and so on(4) side light LED:0905 (22*12), 1105 (28*12) 1605 (40*14) and so on.
What determines the brightness of the patch LED?
The brightness is consistent over a short period of time, that is, only by considering current and voltage consistency.Long term brightness is consistent with the consideration of the spacing and heat dissipation of different circuits. Uneven heat can also affect brightness.
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.
What does patch LED light mean?
The screen is divided into standard lamp and patch type, the light emitting diode lamp is inserted into the circuit board, and the patch is a patch welded on the circuit board. Two light sources are not the same. If only light, not so clear.
