FAQ

Is the forward voltage drop of the patch LED too large or too small?
If you have to be good or bad, then I can say "small" to you,Some clients have strict requirements for this
Indoor full color LED display module and LED what is the difference between a full color?
(1): LED full color light emitting module display module is generally yellow green, pure green module price is more expensive; SMD full color LED display using pure green tube coreThe display module (2): LED full color pixel visual feeling is thick, low brightness, easy to have the mosaic phenomenon; patch LED full color consistent, high brightness;(3): maintenance module LED full color display is not easy to maintain, the whole module replacement cost is high; SMD full-color LED screen for easy maintenance, repair and replacement of single lamp;
What is the difference between patch LED beads and LED beads: General
Patch is a LED lamp, 0805, SMD beads 3014, 3528, 2835, 5050, 5630, 5730 and so on.
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 are the storage requirements of SMT patch LED (LED)?
Moisture-proof packing- anti SMD LED in the transport and storage of moisture absorption, SMD LED shall be placed in sealed moisture-proof bag, inside put damp proof agent for protection, and placed the humidity humidity SMD display card packaging bag.
What is the difference in performance between the LED plug-in and the LED patch?
1, the patch is relatively easy to heat dissipation, can be directly welded on the aluminum substrate, heat faster.2, in general, there is a straw type shell, general lighting has front facing directivity, just look at it, brightness will be the biggest. The patch has a relatively wide divergence angle and is more suitable for fluorescent lamps.
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
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.
