Adjustable power supply / driver for the CoB LED array

Adjustable power supply / driver for the CoB LED array

Spec:

- light source: BXRC-40E10K0-C-7X,or CLU058-1825C4.

(Alternative: BXRC-40E10K0-B-7X, BXRC-40E10K0-D-7X)

- power source / driver input: battery, 12 (or 16) pc of li-ion 18650 cells

- brightness adjustable from zero up to the highest possible value (0 -> 120W -> max ??)

- at max power driver must work for a few minutes, from time to time

- working time between charging up to an hour

- driver must have an emergency reaction to prevent overheating of array

Looking for someone who can:

- create a specification

- Design the circuit and PCB

- build and test the prototype

Please let me know about your previous experience in the design of an LED driver, DC-DC converters, and knowledge about lithium batteries (charging / discharging control).

The final budget will be agreed upon after specifying the requirements, feel free to ask more details.

Please provide a preliminary description of the (simplified) functionality and estimate its cost

I have some previous experience with this kind of light. The purpose of this project is to develop a new, third prototype, using the newly introduced CoB arrays on the market.

Skills: Circuit Design, Electrical Engineering, Electronics, PCB Layout
