Q: 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.

Q: Indoor full color LED display module and LED what is the difference between a full color?: The classification of the LED display according to the installation environment: indoor LED display screen, semi outdoor LED display, outdoor LED display; according to color: color LED screen, dual color LED display screen, LED display screen, the color LED display screen; according to the functional area can be divided into graphic screen, screen, screen, screen, digital dot matrix digital hybrid screen.

Q: What should I notice when I want to solder 1206 LED patch type luminous tube on fine copper wire?,: It is best to use a hot-air gun heat transfer high air volume adjustable low moment welding, the specific heat jump to the appropriate place to see what you use what kind of welding wire, welding wire of different because of the different melting point impurities also some differences. The air volume is too high, easy to blow the original

Q: What, in what way do I shunt the LED?: LED lights are current driven, first of all, look at your LED's IF and VF values. How much power do you have?. Make sure the current is in line with the IF and the current limit can be achieved with resistors.

Q: 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!

Q: What is the difference between patch LED beads and LED beads: General: A pin of the lamp, and outside a resin cap, because the reason LED beads can spotlight cap;There is no pin on the patch and there is no resin cap outside. Because of the lack of cap, the LED patch can not be concentrated.Patch is based on small power, the shape is relatively small (usually 0.5 and 0.5W products)It's called patch because some small ones need Mounter to machine.The ordinary LED lamp, solder joints than SMD beads, now is the largest artificial welding. Regular watts count from 1-300W

Q: Patch LED market conditions: Patch LED (SMD LED) is mainly used in lighting systems, decoration, electronic equipment, indicators, backlight, monitors and instruments and other fields. The decline in handset and LCD TV production in 2009 could affect the supply expectations for such components.

Q: 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

Q: How many volts is a single LED on the LED patch band?: 3V or so, generally three, a group plus a resistor, power supply with 12V

Q: What is the difference in performance between the LED plug-in and the LED patch?: The cooling of the plug-in is not good, because the plug-in's lamp foot, in order to save costs, generally use iron plus coating, heat conduction is not very good.The strength of aluminium alloy is not enough, it is easy to break, and copper is expensive.Relatively speaking, the patch is good, because the heat is welded on the PCB, copper or direct aluminum substrate cooling, patches near.Otherwise, why do high-power patch it?!SMT direct placement machine, a high degree of automation, low rate of bad.
