Embodiment Construction
[0039] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.
[0040] Example. Large chip of LED driving power supply: including a second transparent substrate 413 with a fixed width of W, the second transparent substrate 413 is printed with a silver paste circuit, an interface wire is formed on the silver paste circuit, and the interface wire has an input end and an output end; The width of the input end and the width W of the lead access end of the optomechanical template 43 G The same or have a pad connected to the electrical connector; there are N+1 parallel interface wires on the silver paste circuit at the output end, and the distance between two adjacent interface wires is W JG It is equal to W minus the interface wire width and then divided by N(W JG =(W-interface wire width) / N); On the second transparent substrate 413, first stick unpackaged power dr...
