The present invention relates to a street lamp reflector, and more particularly to a street lamp reflector for improving the illuminance of the street light illumination light, and a street lamp device having the same.

Incandescent lamps, such as fluorescent lamps are widely used in lighting lamps, such as street lamps, and in recent years, the use of high-brightness LED as a light emitter is gradually expanding.

In the case of the lamp for the street lamp as described above, since the direction of emitted light is not constant, in order to intensively illuminate a desired area, a reflection shade is generally installed on one side of the lamp. The reflector is used to recover the lost light (backward illumination) when it is not used and to direct the light where it is needed.

Therefore, the reflection shade needs to increase the reflectance of the backward light and to concentrate the rearward light to increase the illuminance, and the light diffusion is required to reach a sufficient amount of light in a certain area.

However, the conventional reflector has a configuration in which the reflective surface reflecting the light of the lamp is smoothly coated or formed of a smooth metal material to reflect the light. In the case of having a reflection shade has a limit to brighten the light from the lamp where necessary, there was a limit to increase the reflection efficiency.

1A to 5, the reflector 10 for a street lamp according to the exemplary embodiment of the present invention is mounted to the reflector mounting unit 120 of the apparatus main body 110 of the street light device 100. Here, the reflection shade mounting portion 120 has a structure in which the reflection shade 10 is accommodated therein and mounted in a predetermined depth from the lower side of the apparatus main body 110. The lamp 130 is mounted inside the reflection shade mounting unit 120, and the lamp 130 is coupled to be exposed to the outside of the reflection shade 10.

The reflection shade 10 includes a first reflecting member 20 and a pair of second reflecting members 30 symmetrically coupled to both sides of the first reflecting member 20.

The first reflecting member 20 includes first and second main reflecting surfaces 22 and 23 asymmetrically provided at both sides with respect to the bent portion 21 bent at a predetermined angle, and the first and second main surfaces. The first and second edge portions 24 and 25 are bent and extended at both ends of the reflective surfaces 22 and 23, respectively. The first main reflecting surface 22 is formed to have a larger area than the second main reflecting surface 23, and thus the first main reflecting surface 22 is formed longer than the second main reflecting surface 23. Each of the first and second main reflecting surfaces 22 and 23 is formed to gradually expand its width toward each of the first and second edge portions 24 and 25 with respect to the bent portion 21.

The first main reflector 22 is formed with a lamp coupling hole 22a for coupling the illumination lamp 130, and the second main reflector 23 has a reflector 10 at the main body of the lighting apparatus 100. A fastening hole 23a through which a fastening member such as a screw to be coupled to is formed. In addition, a plurality of coupling holes 26 for coupling with the second reflection member 30 are formed at the side edges in the width direction of the first reflection member 20. The coupling hole 26 is formed in a slit shape, it is preferably arranged at regular intervals.

The pair of second reflecting members 30 are symmetrically coupled to both sides of the first reflecting member 20, and have a triangular shape in planar shape, an auxiliary reflecting surface 31, and a third edge portion. And a coupling rib 33. Sides 31a and 31b of the auxiliary reflecting surface 31 corresponding to the first reflecting member 20 have different lengths, and coupling ribs 33 protrude from the sides 31a and 31b. It is formed at a position corresponding to the coupling hole 26.

Therefore, the first reflecting member 20 is bent at a predetermined angle with respect to the bent portion 21, that is, the first reflecting member 20 is bent by the angle θ between the sides 31a and 31b. In this state, the coupling ribs 33 of the second reflection member 30 are inserted into the coupling holes 26 of the first reflection member 20, and then, as shown in FIG. 2C, the coupling ribs 33 are formed. By bending the) and fixed so as not to fall out of the coupling hole 26, it is possible to combine the first and second reflecting members (20, 30).

Also preferably, as shown in FIG. 2D, the heights of the embossed embossed portions 20a and 30a are processed to a height h less than or equal to the thickness t of each of the first and second reflecting members 20 and 30. It is good to be processed. By forming the embossed portions 20a and 30a embossed at such a low height to the entire first and second reflecting members 20 and 30, the light emitted from the lamp 130 is effectively scattered to actually light the lamp 130. Since the amount of light can be increased so as to exceed the amount of light emitted from), even if the lamp 130 having a small capacity of the lamp 130 is employed, illumination light beyond the design can be obtained, thereby obtaining an economical advantage.

In addition, the first reflecting member 20 is formed to have the first and second main reflecting surfaces 22 and 23 asymmetrically on both sides with respect to the bent portion 21, thereby directly behind the lamp 130. The corresponding first reflecting surface 22 may be configured to be wider to more effectively reflect the light emitted toward the rear of the lamp 130 toward the front side.

In addition, the first and second main reflecting surfaces 22 and 23 and the pair of second reflecting members 30 are formed to be inclined with respect to the bent portion 21 and disposed to face each other, thereby providing a lamp 130. By condensing the light from) to the desired area to the desired area, it is possible to increase the efficiency of the street light.
