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
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
Patch LED market conditions
Chinese suppliers also offer mature, but less profitable two-color and trichromatic products, which are mostly used in backlighting, appliances, consumer products, consumer electronics and display. Despite low market demand, vendors continue to offer sideview SMD LED, including 335 (4008), 020 (3806) and 215 (2810)
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.
How to detect LED SMD beads
Now the LED lamp, drop it in general about 3V, so the general multimeter is not measuring it.
Does anyone know what the current rating of a white high brightness LED patch is? Where can I find out?
Generally small power LED rated current is basically 20mA
What does patch LED light mean?
Look, what's your product?. Some products have volume requirements, straight line will be relatively large, patches of small affixed to the circuit board does not occupy space, if only the light source, it may be an ordinary light bulb, as LED power saving.
What is patch SMD-LED?
Semiconductor wafers consist of two parts, one is P type semiconductor, in which the hole dominates, and the other end is N type semiconductor, which is mainly electronic here. But when the two semiconductors are connected, they form a P-N junction between them. When the current passes through the wire acting on the chip, the electrons are pushed into the P region. In the P region, electrons combine with the hole and then emit energy in the form of photons, which is the principle of LED luminescence. The wavelength of light, that is, the color of light, is determined by the material that forms the P-N junction.
