LIGHTING APPARATUS FOR EMITTING VISIBLE RAY UNDER WATER WHICH IS EQUIPPED WITH DUPLEX COMMUNICATION SYSTEM

摘要

The present invention relates to a light apparatus for emitting a visible ray under water, which is based on a high-power white LED and is equipped with a duplex communication system and, more particularly, to a technology capable of performing a high-speed duplex visible ray wireless communication function while an LED is used as low power/high illuminance lighting equipment under water. The apparatus for emitting an visible ray under water, which is equipped with a duplex communication system, according to the present invention, is equipped with a motor-driven actuator which may adjust a distance between an LED and a Fresnel lens. Further, when the apparatus is used for lighting, the Fresnel lens is situated farther than a focal distance, so that light of the LED is diffused, and when the apparatus is used for communication, the LED is situated at a focal distance of the Fresnel lens, so that parallel light is generated, and thus a communication distance may be expanded.;COPYRIGHT KIPO 2016
