BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting apparatus, and more particularly, to a lighting apparatus using a light emitting diode (LED) or an organic light emitting diode (OLED) as a light source.

In general, incandescent lamps or fluorescent lamps are widely used as indoor or outdoor lighting lamps. In addition, street lamps installed on the road are installed such that sodium lamps or ordinary metal lamps are regularly arranged at intervals of approximately 30M to 50M along the road. The incandescent lamp used as a light source of the illumination is less efficient by heating the filament to generate light, and the fluorescent lamp generates light by emitting a phosphor, which has less power consumption than the incandescent lamp, but has a phosphor inside. Hazardous mercury (Ag) is used. In addition, sodium and metal used as a light source of the street light also has the disadvantage of high power consumption and short life.

In recent years, lighting apparatuses using LEDs or OLEDs as light sources have been developed. In the above, LED or OLED has a long life and low power consumption. In particular, the lifespan is more than three times longer than general fluorescent lamps and has excellent performance as a lighting material because it has brightness equivalent to fluorescent lamps in brightness.

However, a light source using an LED or an OLED has excellent brightness but a small viewing angle, and there is a problem in that the light source is extremely limited due to the heat generation problem of the light source.

Therefore, the necessity of the development of a lighting device that solves the small viewing angle and the heat generation problem of the light source by using LED or OLED as a light source is increasing.

Combined by doing. Rotating end 75 is the tooth is formed to correspond to the surface in contact with the one surface is formed in the secondary chatter teeth of the hinge shaft (39). Therefore, it is possible to adjust the degree of rotation when the plurality of optical module 63 is rotated about the hinge axis (39).

Surface where the teeth of the hinge shaft 39 is formed when the optical module 63 is rotated by an elastic body (not shown) formed of a rubber ring, a silicon ring, a coil spring, or a leaf spring installed on the hinge shaft 39. While increasing the contact force of the toothed surface of the rotating end 75 and the predetermined angle allows to maintain the angle after rotation. In addition, when rotating, the optical module 63 is easily rotated by the elastic body.

In addition, each of the plurality of optical modules 63 has a plurality of light emitting elements 67, preferably 1 to 24 light emitting elements 67 on the printed circuit board 65 is formed long in a narrow width 1 ~ It is formed to be mounted in two rows. The plurality of light emitting elements 67 may be configured as LED or OLED. Since each of the light source units 61 is formed of a plurality of optical modules 63, only the broken ones can be replaced during repair, thereby reducing maintenance costs.

In the light source unit 61, a plurality of optical modules 63 are hinged to each of the plurality of holders 33, whereby the number of optical modules 63 is increased by the number of times of the plurality of holders 33. The amount of light can be increased. In addition, the light source unit 61 may adjust the irradiation direction of light in a unit hinged to each of the plurality of holders 33, so that the plurality of optical modules 63 may be evenly illuminated.

In the above, one or more light sources 61, preferably a plurality of optical modules 63 hinged to the outer circumference of each of the two to three holders 33 are rotated by the capping unit 31. It may be installed so as not to overlap. As a result, the light generated by the plurality of optical modules 63 installed in the upper part is blocked by the plurality of optical modules 63 installed in the lower part, thereby preventing the light efficiency from being lowered.

In the plurality of light emitting elements 67 constituting the plurality of optical modules 63, any one of the elements generating light of red (R), green (G), blue (B) and white (W) Is selected. In addition, the plurality of light emitting elements 67 constituting the plurality of optical modules 63 is a printed circuit board with the same elements that generate light of red (R), green (G), blue (B) and white (W) It may be mounted on 65.

Each of the plurality of light emitting elements 67 constituting the plurality of optical modules 63 is sealed by the lens 69. Each of the lenses 69 is formed of a hemisphere or an ellipse made of a transparent synthetic resin by diffusing or focusing light emitted from the plurality of light emitting elements 67. In addition, each of the lenses 69 may be formed of a translucent synthetic resin to prevent glare from light emitted from the plurality of light emitting elements 67.

The lens 69 is formed to have a smaller radius of curvature from one side of the plurality of optical modules 63 to the other side so that light emitted from each light emitting element 67 is far away. As a result, the lighting apparatus according to the present invention can further improve the uniformity of light at a portion bordering with an adjacent lighting apparatus when used in a street lamp or the like.

In addition, each of the plurality of optical modules 63 is sealed by a cover 71. The cover 71 is formed in a semi-cylindrical shape of a transparent synthetic resin.

Although the plurality of optical modules 63 includes a lens 69 and a respective cover 71 covering each light emitting element 67, the lens and the cover may be formed as one body in the present invention.

Each of the heat sinks 73 is formed of copper, aluminum, magnesium, ceramics, or an alloy thereof having excellent heat transfer characteristics, and the lower portion of each printed circuit board 65 on which the light emitting element 67 is mounted. Abuts. Therefore, each of the heat sinks 73 can effectively radiate heat generated during the operation of each light emitting element 67 to the outside.

The closing cap portion 81 prevents one or more capping portions 31 fitted through the tube 23 from being removed from the tube 23. The closing cap 81 is formed in the shape of a disc having a larger diameter than the tube 23 is screwed to one end of the tube (23).

The lighting device according to the present invention having the above-described configuration has a capping part 31 composed of one or more, preferably two or three, in which a plurality of optical modules 63 are hinged to the outer circumference of each holder 33. ) Is inserted through the tube 23 and the closing cap 81 is screwed to one end of the tube 23. The capping part 31 is fitted to the tube 23 so that the guide protrusion 43 of the liner 41 coincides with the guide gap 25. In the state where the stop protrusion 45 of the liner 41 is accommodated in any one of the plurality of stop grooves 29 and no force is applied, the capping part 31 slides between both ends of the tube 23. To prevent it from being moved.

And, by applying a force to the capping portion 31 by sliding the outside of the tube 23, the separated one side of the liner 41, the stop projection 45 is formed is deformed by elasticity. That is, when the stop protrusion 45 formed on the separated side of the liner 41 is out of the stop groove 29 of the tube 23, the separated side of the liner 41 is deformed by the stop protrusion 45 so that the capping part is formed. The 31 can slide easily on the outer side of the tube 23. At this time, the capping part 31 is moved by sliding the outside of the tube 23 in a state in which the guide protrusion 43 is fitted in the guide gap 25 is not moved to the left and right.

In addition, when the capping part 31 is rotated in a left or right direction about the tube 23, a plurality of optical modules 63 connected to each of the plurality of capping parts 31 are extended to different capping parts 31. The light efficiency may be increased by preventing the plurality of connected optical modules 63 from overlapping each other. At this time, since the fixing ring 47 has elasticity, the capping part 31 is easily rotated because it is easily tensioned.

In the light source unit 61, since the plurality of optical modules 63 are hinged to each of the plurality of holders 33, the number of the optical modules 63 increases by a multiple of the plurality of holders 33, thereby increasing the amount of light. have.
