Where can I find a specialist to disassemble and describe the components of a household lighting fixture?

Question

Do it yourself

A description of the LED, wireless lamp is required: type of LED, materials, circuit, etc.

Answer 1

Perhaps you should clarify your question. If the question is "where?", then the answer can be very broad, ranging from students of technical universities, and ending with a familiar development engineer.
Or do you need to create some analogue of the design documentation for the lamp? In this case, if you set yourself the goal of doing everything right, then there will be certain difficulties. The brand of the LED is almost impossible to determine, they do not write on them, and cannot be determined by inspection. It is also not always possible to determine materials by eye, there are too many of them now. Make laboratory chem. I do not offer analyzes and microsections.
If you need something like a student's course paper in a design specialty, then everything is simpler. Any LED suitable in design and luminous intensity. The materials are similar.
The circuit is copied from the board if there are no difficulties in the form of multilayering, the impossibility of viewing through the light, etc. Any suitable steel is indicated, powder coating, etc.
P.S. Or did you mean that you need a specialist who would create for you design documentation for some kind of LED lamp? Then the answer is according to the variant with a student course paper. And any student can do it. Also, of course, any constructor. Because the task is trivial.

Answer 2

LED, wireless?
I'm probably not a big specialist in electrical engineering, but it turns out something funny.
