Abstract: A test apparatus includes a lighting unit radiating light on a to-be-tested object having a light transmitting resin containing a light conversion material; a camera unit obtaining an image of the to-be-tested object while the light transmitting resin is emitted by receiving light emitted by the lighting unit; and a controller determining whether the to-be-tested object is defective by calculating gray values from the image obtained by the camera unit.

Abstract: Manufacturing a light source module may include mounting light emitting devices on substrates on an upper surface of a carrier, mounting optical devices to cover the light emitting devices, and inspecting the light emitting devices and the optical devices based on selectively capturing images thereof. Images may be captured based on controlling a light source module scanner assembly on the carrier. The substrates may extend in a first direction and may be spaced apart in a second direction. Controlling the light source module scanner assembly may include moving the light source module scanner assembly along a selected direction to position the light source module scanner assembly on at least one of the light emitting devices and the optical devices. The direction may be selected based on the quantity of substrates and the quantity of light emitting devices and optical devices on each of the substrates.
