TUNNEL LAMP USING LIGHT EMITTING DIODE

摘要

A tunnel lamp using a light emitting diode is provided to control the brightness of the lamp by controlling the switching on and off of the lamp according to a time band by dividing the number of diodes into groups. A tunnel lamp using a LED(Light Emitting Diode) includes an LED substrate(110), a reflector(130), a lamp body(140), a power connector, and a control unit. A number of diodes are installed in parallel and in serial reciprocally on the LED substrate(110). The reflector(130) installed in the upper surface and sides of the LED substrate(110) reflects the light emitted from the diodes. The lamp body(140) includes the embedded reflector(130) and LED substrate(110). The power connector includes a first connector and a second connector to correspond to each other and be fixed on a metal caps which are fixed on both side of the lamp body(140), and supplies power to LEDs of adjacent lighting devices, and is physically connected through adjacent lighting devices and the first and second connectors. The control unit receives and converts power according to the need of the LED substrate(110) and controls the switching on and off of the LEDs.
