Q:Is the forward voltage drop of the patch LED too large or too small?: Pressure drop does not mean good or bad, the greater the pressure drop, the better to choose the right for you

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:Patch LED light broken one, short circuit can use it?: Only when a constant current source is used, the LED in series can be shorted. For the shunt power supply shunt LED, the open circuit LED can be disabled without having to manage it. The short circuit must be removed

Q:Production of a number of substrates, the use of SMD LED lights, red lights and green lights are not bad, blue lights appear mass dark, do not know why? Is the LED blue light material easy to use dark?: If you choose the brightness of blue light in the light of the relatively high, so when debugging the white balance (by changing the resistance to change the current, and then change the RGB brightness LED lamp), it is difficult to transfer to the pure white. Therefore, when selecting the lamp, the blue light is generally not bright.

Q:Such as title, please have welding patch LED lamp experience expert guidance, do not search from the Internet to the theoretical knowledge, thank you!: If the power of the lamp, because heat high power do very well, so not good welding, the temperature at the highest (300 degrees), the use of horseshoe iron head, not waiting to solder, because the heat is very powerful, quick action.

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.LED patch lamp is made of FPC circuit board, LED lamp and high quality silica gel sleeve. Waterproof performance, using low voltage DC power supply is safe and convenient, light colors, bright colors; outdoor use can be anti UV aging, yellowing, high temperature resistance and other advantages, the products are widely used in building lights, decorative lighting, advertising and entertainment quasi decorative lighting lighting field.

Q:What, in what way do I shunt the LED?: In series, the voltage is 20 times the rated voltage, in parallel, the voltage is rated voltage, but in tandem, a LED is broken, it is not bright, so it is recommended not to use it.

Q:What is patch LED?: LED is usually the lead pins form, need to be drilled on the printed circuit board, the LED pin is inserted in the hole, welded with wave soldering machine; and the patch type LED is used in welding surface, flat welded on the circuit board.

Q:What are the storage requirements of SMT patch LED (LED)?: Clean? use no designated chemical liquids to clean SMD LED. These chemicals may damage SMD LED.. When necessary, wipe LED at room temperature with alcohol and dry at room temperature for 15 minutes before use? the effect of ultrasonic cleaning on SMD LED is related to the ultrasonic power and the SMD LED assembly method, and shall be checked in advance to ensure that the ultrasonic cleaning process does not impair the SMD LED

Q:SMD LED lamp working voltage?: LED is a light emitting device of low voltage, low current, low power forward current general patch type LED when using (IF) 20MA, (VF) 1.8-2.5V, voltage of red green and blue (VF) voltage is 3.0-3.6V. Different manufacturers also have small differences, so first of all, look at the color,Of course. The multi chip assembly in high voltage chip together, some current: 1 watts, 1 watts and above.
