METHOD OF INSPECTING LIGHT SOURCE MODULE FOR DEFECTS, METHOD OF MANUFACTURING LIGHT SOURCE MODULE, AND APPARATUS TO INSPECT LIGHT SOURCE MODULE

摘要

According to an embodiment of the present invention, a method to inspect a light source module for defects comprises preparing a board on which a light emitting device and a lens covering the light emitting device are installed. A current is applied to the light emitting device to turn on the light emitting device, and the lens is imaged with the light emitting device turned on. A central symmetry denoting a symmetry of light emission distribution from a center of the lens is calculated based on the obtained image, and the calculated central symmetry is compared with a reference value to determine whether unsymmetrical light emission distribution has occurred.;COPYRIGHT KIPO 2016
