If the Leds are not in close proximity then LDR's can be used connected to a node on the ICT/wired into a micro for a simpler board - you can then test for luminous intensity as well as absence. Else you could use a cheap CCD camera with some simple

We don't coat anything in a socket or any test points or connectors, switches, leds, wire holes, grounding pads good luck

I have about 9 Super Bright LED's in my car. I use a 560 ohm Resistor 1/2 watt soldered in-line to the longer lead of the LED. Works fine. http://www.superbrightleds.com

I need to wire some LED's. I have a pair installed in my headlights that use some sort of small thing at the end of the wire. They run off of the 12 volt car battery. They can stay on for over a month without starting the car and still not drain the

Look here: http://www.acroname.com/howto/LED/LED.html If you don't know the current, experiment with different values of resistor. Starting with the highest value resistor that doesn't dim the light too much then lowering it as needed. Connect th

Hombre, presuming you are doing this as enhancement for looks, I have some comments. 1. LED's seldom run on more than 3 volts. 4.5 volts max for some special types. Because the car is 12 volts all over, you have to use a resistor to reduce the v

Thank you guys for your help, I do not clean any on my assemblies who are build by the SMT an wave soldering department, we do used liquid fluxes Kester 951 and cored wire keester 245, usually it�s for batteries connector, led, terminal and wire rap

For typical small sized circle LED panels, you can simply have a PCB routed to said circle... but when lighting fixtures are sizes 2-3 feet+, and a circular, typically how are the LEDs being spread across the radius? I can see flex LED strips being

A light emitting diode or "LED" doesn't care about voltage, it will light with approx. 10 to 20 milliamps of current. In a 12V system (such as an auto), a resistor of 1K ohms is ideal. At 12V, this allows about 12 mA of current, at 13.8V (approxima

Hello Glenn, thanks a lot for your response. The company I work for is launching LEDs production this year. We'll need to do a number of the environmental tests in our quality control laboratory. So the application for SAM and Xray systems is inspect
