Q: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
Q:SMD LED specification
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.
Q:How does the LED patch lamp differentiate between positive and negative poles?
Because the LED open threshold is about 1.5-1.8V. It is possible that the voltage supplied by the digital multimeter does not activate it. So look at the sign. Patch LED (SMD LED), the green point of negative, relative to the positive.
Q:Patch LED light does not flash, why?
There are three main reasons:1, the temperature is too high, resulting in LED lights, dead lights.2, do not do anti-static measures, electrostatic breakdown chip, resulting in damage to the LED light.3, the use of LED lamp quality is too bad, the purchase price reasonable LED lights
Q: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;
Q:The quality of the LED patch module
Chip size. The larger the size of the same chip, the higher the general brightness, the stronger the bearing capacity, the higher the stability performance, of course, the price is relatively high. The size of the module chips now includes: 9MIL, 10MIL, 12MIL, 14MIL, 23MIL, and so on.
Q:What does "1210" mean in patch LED?
1210 represents the size of the LED package specification (size, specification), and represents the length and width of the resistanceSpeed adoption!!!
Q:Welding method and notice of SMT LED
I recommend reflow soldering under normal conditions and manual welding only when repaired. 2 manual soldering electric soldering iron maximum power can not exceed 30W, welding temperature is controlled within 300 degrees, welding time less than 3 seconds. 3 do not touch the colloidal iron welding head. 4 when the pin is heated to 85 degrees centigrade or higher than this temperature, it can not be pressed. Otherwise, the welding will be broken.
Q:What is the difference in performance between the LED plug-in and the LED patch?
The same, stick pieces is an early product, stick pieces than patch mature, stick pieces of my lamp has almost can not see what changes for three years with only a patch of brightness, years have been feeling a lot of dark. I believe the quality will be good soon.
Q:Patch LED features
The seismic resistance, high reliability, low operation cost system.It is easy to small, thin, lightweight, easy to shape without restrictions, made all kinds of application.
