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 beads can be bought in what place?

SMD LED lamp is now very popular, mainly because of long service life, but also rarely appear dead lights or dark, but there are many defects exist

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:Such as title, please have welding patch LED lamp experience expert guidance, do not search from the Internet to the theoretical knowledge, thank you!

When soldering, the temperature is best to be lower, and the average welding temperature is about 360. That's enough, because the melting temperature of the tin wire is about 220 degrees, so if it is allowed, the temperature can be reduced as low as possible.

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. A wide variety of varieties, as follows:

Q:LED light SMD LED package in what form, trouble you under the guidance of...

There are 3 types of LED packages: inline LED, piranha LED, and surface mount LED

Q:LED package and LED SMD LED lamp, what is the difference? Will the release agent be used in that part?

Packaging is for TOP series LED, that is, the type of plastic molding. The patch is based on the PCB circuit board for molding. Mold release agent is used in molding.

Q:How does the LED placement lamp distinguish the positive and negative poles? There is no sign on the light. Thank you

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: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?

If you take a large area light, to see that the lighting requirements, functional lighting, or lighting atmosphere, or ordinary lighting, which is to be considered, the two optical (lens) can bring you the light angle planning.
