Abstract
An LED chip package structure in order to prevent the light-emitting efficiency of fluorescent powder from decreasing due to high temperature includes a substrate unit, a light-emitting unit, a transparent colloid body unit, a fluorescent colloid body unit and a frame unit. The light-emitting unit has a plurality of LED chips electrically arranged on the substrate unit. The transparent colloid body unit has a plurality of transparent colloid bodies respectively covering the LED chips. The fluorescent colloid body unit has a plurality of fluorescent colloid bodies respectively covering the transparent colloid bodies. The frame unit is covering the peripheries of each transparent colloid body and each fluorescent colloid body in order to expose the top surfaces of the fluorescent colloid body.
