摘要

A white light source module using LEDs includes a substrate, a plurality of white LED lamp beads and red LED lamp beads arranged on the substrate according to the number ratio of 2:1. A blue LED chip is provided in the white LED lamp bead, and the colloid mixed by yellow and green fluorescent powder is coated on the blue LED chip. A red LED chip is provided in the red LED lamp bead. The white light source module using LEDs has a simple structure, and achieves high light emitting efficiency,low color temperature and high color rendering property utilizing only two kinds of LED light beads.
