The invention provides an LED light source capable of weakening blue light harm. The LED light source comprises a blue light chip and a glass light-conversion light-emitting assembly. The glass light-conversion light-emitting assembly is composed of borosilicate glass uniformly dispersed with cerium-activated yttrium aluminum garnet fluorescent powder and a glass substrate with one surface coatedwith red fluorescent powder. The red fluorescent powder is red fluorescent powder excited by blue light; one surface of the glass substrate, which is coated with the red fluorescent powder, is clung to the borosilicate glass; the glass light-conversion light-emitting assembly is arranged, the fluorescent powder is uniformly dispersed in borosilicate glass, and the consistency of LED light source and the luminous stability of phosphor are improved; and meanwhile, the blue chip further excites red fluorescent powder, overflow of blue light of the lamp is reduced, red light is increased, color temperature is reduced, and the problems of aging, color drift and blue light overflow of a resin packaged LED in the prior art can be effectively solved.
