Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reflector for a lighting fixture,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reflector for a lighting fixture and a lighting apparatus having the same, and more particularly, to a reflector installed inside a lighting apparatus to provide a high contrast and a lighting apparatus having the same.

A general lighting apparatus is a mechanism for efficiently irradiating light generated by a light source such as a bulb. The lighting fixtures are installed in the indoor as well as outdoor areas and brighten the desired areas.

Most conventional lighting apparatuses include a frame, a light source, and a light source. A light source is fixed to the frame, and a light source, which is also called a reflection gutter, is provided around the light source. The back light guides light more effectively by guiding the direction of light appropriately.

The lighting device is mainly provided on the upper side of a room such as a ceiling. Since a part requiring illumination is a space on the lower side of the room, it has a lamp for collecting and radiating light emitted from the light source in all directions. So that the illuminance can be further increased.

The better the structure of the lamp, the higher the illuminance can be obtained even if the same light source is used. In general, the efficiency of the lighting apparatus varies greatly depending on the reflection efficiency of the light bulb.

In the conventional lighting apparatus, the light emitted from the light source located in the back light is directly reflected to the outside or is reflected to the outside. In this case, since the illuminance of the light directly irradiated from the light source and the light reflected by the light source is considerably different from each other, the degree of glare is considerable, and the light directed toward the side is small.

In addition, since the light emitted from the light source is multiply reflected from the light source, significant light loss occurs, and since the light source itself interferes with the light path, the absolute illumination amount per each position is low.

Korean Registered Patent No. 10-984254 (on-site simple attachment type high-intensity reflector and method of selling the same) discloses a reflector used as a supplementary light source in combination with a conventional lighting apparatus.

In Fig. 1, the reflector 200 disclosed in the aforementioned patent is illustrated before being assembled. When each of the two protrusions 202 is fitted into the two insertion holes 204, a truncated cone-shaped reflector having upper and lower openings is formed.

The reflector 200 is inserted into the interior of the lamp of a conventional lighting apparatus and then attached to the lighting apparatus using an adhesive tape 206 provided at the lower portion of the reflector 200.

However, in the above-described conventional patent, since the reflector 200 is attached to the lighting apparatus using an adhesive tape, the adhesive tape is melted by the heat generated from the light source, and the reflector is detached from the lighting apparatus .

In addition, in the above-mentioned conventional patent, a person is directly raised to the lighting apparatus installed on the ceiling, and then the lamp is removed from the lamp, and then the auxiliary lamp is connected to the lamp by using a fixing member. There was a problem that it was uncomfortable.
