Abstract

The present invention relates to a United Reflection Lights with Light-Emitting Diode (LED). In accordance with the present invention, the United Reflection Lights with LED consists of a housing; LED light sources which are installed with an inclination angle to the opposite inside wall of the housing and emit rays in forms of dots to the inside of the housing; and a reflecting plate which, placed in the bottom of the housing, reflect asymmetrically the incident rays originated from the above LED light sources with a number of triangle-shaped projecting parts and act as an indirect lighting device as it lets each of the above mentioned asymmetrically reflected rays combine and go to an intended direction in the form of a plane light source. The surface of the reflecting plate is covered with high polished synthetic resin. The reflecting plates vary according to at least one of the factors, whereby the plates become inter-changeable, such as the number or size of the projecting parts, the forming angle and the space between each projecting part.

In accordance with the present invention, the United Reflection Lights with LED enhances the efficiency of lighting and minimizes the energy consumption because all the rays, originally in forms of dots, are asymmetrically reflected on the reflecting plate and combined to emit in a formation of a plane light. The United Reflection Lights with LED can be adapted to indoor lamps such as fluorescent lamps and to all the outdoor lamps such as street lamps because it needs only a few LEDs whereby its structure can be simple and the cost decreases and also because its indirect lighting method minimizes the radiance. It can enhance the diffuse-ability of rays to the arrangement or longitudinal direction of a projecting part of the reflecting plate by controlling the angle of LED arrangement or forming the projecting part. Also it prevents the LEDs from the damage caused from heat by cooling the rising temperature of the circuit board with the reflecting plate functioning as a radiator.

Claims

1. A united reflection lights with LED, comprising;

a housing;

a number of LED light sources which are installed with an inclination angle to the opposite inside wall of the housing and emit rays in forms of dots to the inside of the housing;

a reflecting plate which, placed in the bottom of the housing, reflect asymmetrically the incident rays originated from the above LED light sources with a number of triangle-shaped projecting parts and act as an indirect lighting device as it lets each of the above mentioned asymmetrically reflected rays combine and go to an intended direction in the form of a plane light source, wherein the surface of the reflecting plate is covered with high polished synthetic resin, and the reflecting plates vary according to at least one of the factors, whereby the plates become inter-changeable, such as the number or size of the projecting parts, the forming angle and the space between each projecting parts.

2. The united reflection lights as claimed in claim 1, wherein both ends, from the projecting part formed in the central area on the reflecting plate as a base point, form flat.

3. The united reflection lights as claimed in claim 1, wherein the LED light sources, which installed at both ends of walls from the projecting part as the base point, are placed on a slant to the centre of the projecting parts.

4. The united reflection lights as claimed in claim 1, wherein the surface of the reflecting plate is compositely plated with at least one or more of two materials among the following:
