PURPOSE: A light emitting module is provided to obtain warm white light with improved color reproductivity by adding red light from red light sources to white light from white light sources. CONSTITUTION: White light sources(W) is formed by mounting a light emitting diode(LED) package with a blue LED chip(112) and a yellow fluorescent substance on a printed circuit board(PCB)(100). Red light source(R) is formed by mounting an LED package with a blue LED chip(122) and a red fluorescent substance on the PCB. Each LED package includes reflectors(110, 120) with cavities. LED chips are attached on the bottom of the cavities. The fluorescent substances are formed to cover the LED chips.
