Abstract

The invention discloses an LED (light-emitting diode) light source module, which comprises a plurality of light source cells and a substrate. Each light source cell comprises a silicon chip and a chip array; the silicon chip is arranged on the substrate; the chip array is arranged on the silicon chip; the silicon chip comprises an upper surface and a welding face; a circuit is arranged on the upper surface; the silicon chip is provided with a conducting hole; an LED chip is welded on the conducting hole; and the LED chip is connected with the circuit on the upper surface and the welding face. By coating fluorescent powder on the substrate, the LED light source module disclosed by the invention has evener light color; by directly adhering the LED chip welded with the silicon chip on the substrate, the occurrence of open circuit and short circuit is reduced, and heat radiation performance is good, and the packaging is convenient.

Description

technical field [0001] The invention relates to an LED light source module, in particular to an LED light source module and a packaging process thereof.
