摘要： A method for inspecting a light source module for defects includes 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. The lens is imaged with the light emitting device turned on. A central symmetry denoting a symmetry of light emission distribution from the 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. Various other methods and apparatuses for inspecting light source modules are additionally provided.
