$2-12 CAD / hour

I want to make a array of SMT LED's into a COB LED. as many as possible on a small package. Successful candidate will have PCB design and electrical design experience. They should be able to calculate the volts and AMP hours needed to safely power all the LED's in the array. You will also need to select a LED driver (surface mount driver or other) that will power the LED array. Thermal damage to the LEDs is also a factor. These boards will be attached to active heat sinks. Special PCB design will be required to handle thermal runaway

Hello thanks for making this job offering available to me. I am hardware engineers for 6 years, my projects included mostly lighting systems at beginning of my work. I have designed over a dozen of lighting sources, few of them with COB LEDs and aluminum PCBs whihc ought to attached to a heatsink. Let me know if you are interested to talk more. I know my prices is high, but you will be getting job done professionally. Thank you for your time; David

Hi, I'm a telecommunications engineer with extensive knowledge in electronic. I have experience making electronics circuits designs, and PCB layouts for very small products smallest than 2cm X 2cm depends of the product. Do you want to make a real COB LED or a simple array of SMD LEDs similar to a LED lamps? Because COB LED have several LEDs, but this LEDs are without the "package" and are mounted directly to the substrate so need an industrial process for make it. I can help you with the circuit if you want a LED array similar to a LED lamps but maybe smaller (maybe same size that a COB LED). The circuit will be efficient and will have very good brightness, but never the same of a COB. Any questions you have feel free to do it. I will answer as soon as possible. Regards.
