lighting device using touch method

摘要

PURPOSE: A touch type lighting device is provided to improve reaction speed and accuracy by reacting according to the change of light accepting modulus of light which is reflected. CONSTITUTION: A lighting part(100) is composed by installing an LED chip(120) in a substrate(140). A touch plate(200) is installed on the upper side of the lighting part. An optical sensor(110) is installed in a location corresponding to a penetration hole(130) which is formed in the lighting part. A controller determines the change of brightness of the light which is detected from the optical sensor and controls the lightning part. The controller is connected to an external device and controls power of the external device.
