Abstract
A light emitting diode (LED) package structure include an electrically-insulated frame, a trough, a LED chip, a fluorescent colloid and at least two spacing members. The electrically-insulated frame has a surface with four corners. The trough is recessed in the surface. The LED chip is located in the trough. The fluorescent colloid is filled within the trough to cover the LED chip. The spacing members protrude from two of the four corners on the surface, wherein a glue escape gap is defined between each spacing member and a boundary of the trough.
