Q:What does "1210" mean in patch LED?

At present, most manufacturers of SMD light strip used by 3528 and 5050, and 3535 and 5630 in the majority, there are many of the 3528 and 5050 and 3535, such as patch LED used in automotive lighting.

Q:Which is good for LED patch and LED bulb?

LED (light emitting diode) patch (package)LED patch (SMD) made by FPC circuit board, LED, high quality silica gel. The 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 - Entertainment decorative lighting lighting field.LED bulbA solid state semiconductor device that converts electric energy into visible light by means of LED (light-emitting diode), which converts electricity directly into light; LED = Large, Electronic, Display,;

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?

When making a batch of LED lights, the brightness values of various lights are in accordance with certain rules. Due to achieve a white balance, three RGB color brightness required by the ratio of 3:6:1, that is to say the blue light required brightness is very low.

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!

The welding speed and welding time because certainly give light foot heat, so the speed must be fast, tin wire and tip with better, while heating to tin iron head, avoid heating time is too long.

Q:How to detect LED SMD beads

The output voltage of the digital clock diode file is not high, generally below 2.5V, so the measurement of LED lamp does not work, the best way is to external electrical measurement. If there are a lot of beads to measure it, can take a constant current power measurement.

Q:Does anyone know what the current rating of a white high brightness LED patch is? Where can I find out?

The high power 1W is 350MA, and 3W is 700MA. They are all fixed and can be found everywhere.

Q:How do led patches measure good or bad?

The patch LED is also called SMD LED. Its principle of luminescence is to pass the current through the compound semiconductor. Through the combination of the electron and the hole, the excess energy will be released in the form of light to achieve the effect of luminescence.

Q:LED patch lamp band, how to calculate how many watts a meter, such as 3528-60 beads is how much?

3528-60 is 60 meters per lamp, 3528 SMD lamp with no 5050 light, about 10 watts per meter. Copper wires have less resistance and may be less than 10 watts per meter.

Q:Led lamp and Led patch two what is the difference between ah, the feeling is a patch of long service life, whether or not? 5-10 meters pan area lighting lamp selection Everbright shaped or patch shape?

First of all, I want to say, in the same light emitting chip case, two is not what were, just a different process is a DIP plugin, a SMD patch process, the 3 floor of the right, just some high grade patch.

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!
