Abstract
Description
BACKGROUND OF THE
Light emitting diodes (LEDs) produce a small number of carriers (electrons or holes) injected using semiconductor pn junction structures, and emit light by recombination of them. It is widely used, and the range of its use is expanding, such as being used as a lighting fixture in recent years.
In general, lighting fixtures using light emitting diodes consume less energy than conventional mercury or sodium lamps, resulting in low energy consumption, low voltage, low risk of short circuit and electric shock, and excellent brightness, long distance, and long lifespan. Although it is widely used for high efficiency lighting because of its low cost, the light emitting diode has a limitation in that it can be used as a light that needs to be illuminated in a wide space because the light emitting diode has a strong straightness.
The present invention is to solve the above problems to diffuse the light from the light emitting diode to the diffusion lens in order to brighten the space widely, and to reflect the first diffused light in the concave reflector and the second reflected light back to the second reflector It is an object of the present invention to reflect a large area like a conventional lighting fixture by reflecting.
In order to achieve the above object, a plurality of high brightness light emitting diodes are attached to a body to which a fixed printed circuit board is attached, and both ends are attached to the upper part of the body and are convex and hemispherical. Diffusion lens for diffusing light generated from a plurality of high-brightness light emitting diodes from the upper side, and is located on the upper side of the diffusing lens, one side of the transmission window of transparent or opaque acrylic is attached to both sides and the light transmitted through the diffusing lens A concave reflector for first reflecting the light, a concave reflector attached to the center of one side, the other side of which is opened downward and is coupled to the upper part of the other side of the reflecting plate, and a transmission window for transmitting light reflected from the reflecting plate; One side is attached and the other side is open upward and concave It is a feature of the present invention that it is composed of a reflecting plate for secondaryly reflecting the light reflected by the reflector.
As described above, the present invention diffuses the light from the high-brightness light emitting diode in the diffusing lens, firstly reflects it in the concave reflector, and secondly reflects it again in the reflecting plate to obtain diffused light of high brightness. It is effective to make it light.

Hereinafter, the preferred configuration according to the present invention will be described in detail with reference to the drawings.
The light
The
The plurality of high brightness light emitting diodes 4 are fixed in a state of being arranged in a line on the printed circuit board 3 so as to exhibit high brightness and to adjust the intensity of light according to the number arranged on the printed circuit board 3. It is.
The diffusion lens 5 has a thin and transparent hemispherical shape, and both ends thereof are attached to both sides of the upper part of the
The concave reflector 6 is installed at a predetermined interval at an upper center of the diffuser lens 5 and primarily reflects the light transmitted through the diffuser lens 5 to the lower reflector plates 7a and 7b. One side of the transmission windows 8a and 8b made of transparent or opaque acrylic is integrally attached to both the left and right sides.
The transmissive windows 8a and 8b have a concave reflector 6 attached to the center of one side thereof, and the other side thereof is spread downward to be coupled to the upper part of the other side of the reflector plates 7a and 7b. It is intended to transmit light reflected from the
The reflecting plates 7a and 7b are gently concave in shape, and one end is integrally coupled to the upper left and right sides of the
Another embodiment of the reflector plates 7a and 7b is described below with reference to FIG. 4.
The reflection plate (7a) (7b) is one side is integrally installed on the upper left and right side of the body (2) and the other side is in contact with the lower side of the other side of the transmission window (8a) (8b) and the light angle control plate (10a) at the end ( 10b) is provided so as to control the degree of diffusion of light by changing the bending angles of the reflecting plates 7a and 7b.
Hereinafter will be described the operation according to the present invention.
