The present invention relates to a reflector device of a street lamp, and more particularly, a plurality of reflectors for reflecting light generated from a lamp (Lamp), which is a light source, at different angles on an inner surface of a reflector applied to a street lamp. By forming an anti-section, the light generated from the lamp can be irradiated to a predetermined irradiated area vertically downward, irradiated over a wide range from side to side, and induces diffuse reflection of light to illuminate The present invention relates to a lampshade device of a street lamp, which enables to improve remarkably and to save energy by increasing light reflection efficiency.

In general, a street lamp is a high level lamp installed at a road, a sidewalk or an apartment complex at night so that a driver or a pedestrian may have sufficient visibility to prevent traffic accidents and crimes.

In such a street light, various types of reflection shades are applied to increase the reflection efficiency of light generated from a lamp as a light source.

The reflection shade of such a street lamp is usually formed in a shape and size determined according to the size or shape of a lamp, and is formed in a shape of an enclosure in which an opening is formed at the bottom of the lamp and the interior thereof is empty, and from the outside to the inside of the reflection shade. Various types of lamps are configured to be fitted.

However, in the reflection shade of such a street lamp, most of the light generated from the lamp at the time of lighting is reflected from the inner surface of the reflection shade and then irradiated to the outside through the opening of the bottom surface. When the majority of the light emitted from the lamp is reflected on the inner surface of the reflector many times and then irradiated outward through the opening of the bottom surface, a considerable amount of the irradiated light is not concentrated in the predetermined irradiation area. Since it is irradiated to the vicinity of the irradiation area, there is a problem in that desired illuminance cannot be obtained in a predetermined irradiation area.

In addition, in the reflection shade of the conventional street lamp, since the light emitted from the lamp is often out of the predetermined area through the opening of the bottom of the reflection shade as described above, the reflection efficiency of the light is lowered, and the light is lost. There is a problem that energy is wasted as much as possible.

The present invention is to solve such a conventional problem, the object is a plurality of reflections to reflect the light generated from the lamp (Lamp), which is a light source (light source) on the inner surface of the reflection shade applied to the street light at different angles By forming a negative side, the light generated from the lamp can be irradiated to a predetermined irradiated area vertically downward, and a reflection lamp device of a new street lamp can be irradiated over a wide range from side to side.

It includes a third reflecting portion to be diffused irradiated to the outside of the left and right ends of the formed opening wide.

In the present invention, " ∨ " which causes the light irradiated upwardly along the longitudinal center line of the first reflecting portion to coincide with the mounting direction of the lamp to be reflected back at a narrower reflecting angle than the reflecting angle of the light at the third reflecting portion. It has the characteristic that the auxiliary reflection part of the type | mold was formed.

In the present invention, the second reflecting portion is formed to be inclined outward from the front end and the rear end of the first reflecting portion, and the third reflecting portion is formed to be curved at a predetermined curvature radius toward the outside.

According to the present invention, a part of the light generated from the lamp when the street lamp is turned on is irradiated to the predetermined irradiation area through the opening of the bottom, as well as a part of the light emitted from the lamp and the diffusely reflected light from the first reflector By reflecting back and down vertically by the reflecting jaw of the two reflectors, the illuminance of the predetermined irradiation area is remarkably improved.

In addition, a part of the light reflected from the first reflecting portion on the reflector body and the light emitted from the lamp is reflected back at the third reflecting portion forming a flat surface and then diffused and irradiated while maintaining a wide angle to the outside of the left and right ends of the opening. At the same time, a part of the light that is diffusely reflected from the first reflecting part and the light irradiated vertically upward of the lamp is reflected by the "∨" type auxiliary reflecting part and is then irradiated to overlap with the light reflected from the third reflecting part. There is an effect that the roughness of the peripheral portion of the predetermined irradiation area of greatly improves.

As a result, while the reflection efficiency in the reflection shade is greatly improved, the loss of light is minimized, thereby saving energy.
