INFRARED INSPECTING DEVICE USING LED CAPABLE OF REALIZING LOW POWER, LOW HEAT AND UNIFORM IRRADIATION USING LED AS A LIGHT SOURCE

摘要

PURPOSE: An infrared inspecting device using LED is provided to minimize the generation of a hot spot since light emitting from a substrate is reflected from the inside of a housing by the slope reflecting surface of the housing and is radiated to a target through an opening, so the light emitting from the opening is uniformly irradiated.;CONSTITUTION: An infrared inspecting device using LED comprises a substrate(120), a housing(110), and a camera(140). A plurality of LEDs emitting light are arranged on the substrate. The housing comprises a space for holding the substrate. An opening(114), through which light emitting from the substrate passes, is formed on one side of the housing. A reflecting slope surface(112) is formed on the inner side of the housing. The reflecting slope surface slopes to the opening to uniformly light a target on the side with the opening, reflects light emitting from the substrate, and sends it to the opening.;COPYRIGHT KIPO 2012
