LED UNDER WATER LIGHT

摘要

PURPOSE: An LED underwater lamp is provided to install a short-circuit sensor and an illuminance sensor, thereby blocking power supply when a short circuit is generated during operation. CONSTITUTION: A nozzle body comprises a nozzle(102) which is connected to a pumping device(101) in order to spray water. A plurality of LEDs(104) for generating light is arranged in a lighting body(105). A controller(106) controls an operation supplying power to the LED and pumping device for supplying water to the nozzle. A short circuit sensor(110) detects a short circuit state while supplying power to an underwater lamp. An illuminance sensor(111) detects a sunlight amount. A control part controls an operation state of the LED and pumping device by receiving detection information of the illuminance sensor and short circuit information.
