The diffuse cover for an illumination lamp provided with the reflector of the present invention is coupled to an LED illumination light installed on a ceiling as shown in FIG. 1 to reflect and diffuse the illumination downward.

The LED lighting lamp to which the diffusion cover 100 is coupled is provided with a main body 10 in which an upper side is embedded or coupled to a ceiling and an upper plate 20 is coupled to the inside of the main body 10, A plurality of LED modules 21 are spaced from each other.

The diffusion cover 100 of the present invention is coupled to the LED module 21 to reflect and diffuse light of the LED. The LED module 21 is provided with a plurality of spacing gaps 22 are formed on the surface of the diffusion cover 100, so that the diffusion cover 100 can be easily fixed.

After assembling the diffusion cover 100, the louver 30 is assembled to complete the assembly of the illumination lamp.

In the present invention, the LED illumination lamp is shown as an embodiment, but the present invention is not limited thereto, but may be applied to an illumination lamp using various other light sources such as fluorescent lamps, incandescent lamps, and halogen lamps.

The conventional diffusion cover has a problem that the light distribution curve is narrow due to the straightness of light emitted from the LED, the area illuminated by the light is narrow, and the light too strong is projected only in a specific area. The reflection member 40 and the diffusion member 50 are integrally injection molded so that the reflection plate 42 provided on the reflection member 40 is inclined at a predetermined angle and the reflection member 40 There is a technical difference in that a joining portion 41 for fixing to the upper plate is formed at the end.

Hereinafter, the detailed description will be described in detail.

2 and 3, the diffusion cover 100 is composed of a reflection member 40 and a diffusion member 50. The reflection member 40 and the diffusion member 50 are made of synthetic resin And are integrally joined by double injection.

At this time, the diffusion member 50 is made of synthetic resin of translucent material, diffuses the illumination of the LED, and projects the light to the outside. The reflection member 40 is made of an opaque synthetic resin, Reflects the reflected light again, and re-projects it to the outside again through the diffusion member (50).

The reflecting member 40 has a coupling portion 41 for fixing the coupling member to the coupling ring 22 formed on the upper plate 20 at one side in the longitudinal direction and has a constant And a reflection plate 42 is formed to be inclined.

The diffusion cover for an illumination lamp including the reflector of the present invention having the above-described structure is formed by molding the reflective member 40 and the diffusion member 50 into separate molds and then integrally joined by double injection as shown in FIG. 4 , Which is advantageous for mass production.

Further, by coupling the reflecting member 40 to the upper side of the diffusion member 50, the illumination can be reflected downward as much as possible, and the efficiency of the illumination lamp can be increased.

In an embodiment of the present invention, the coupling portion 41 is bent in the longitudinal direction so that the diffusion cover 100 can be closely fixed to the upper plate 20, .

The pair of reflection members 40 are symmetrical to each other and are coupled to the diffusion member 50 and the LED module 21 is positioned in a space formed between the two reflection members 40, Is inclined so that the light reflected at the inner side of the diffusion member 50 can be reflected back downward and the both ends thereof are lowered so that the bottom surface of the reflection plate 42 is coated with a coating layer 42a are further added.

In addition, since the reflection plate 42 needs to reflect the light reflected from the inner surface of the diffusion member 50 again and project it to the outside, it should be formed at a predetermined angle.

In one embodiment of the present invention, the inclination angle? Is preferably within 15 to 30 degrees. If the inclination angle is too small, light reflected at the center of the diffusion member 50 can not be incident on the reflection plate 42. If the inclination angle is too large, the reflected light from the reflection plate 42 can not be projected to the outside There is a problem.

At this time, since the inclination angle varies depending on the reflectance and the refractive index of the material constituting the diffusion member 50, it is determined in the manufacturing step.

5, a separate inner layer diffusion member 51 is disposed inside the diffusion member 50 so as to be adjacent to the LED module 21 as a single body by double injection molding. Can be additionally formed.

The inner diffusion member 51 serves to more effectively scatter the straightness light emitted from the LED module 21.

6, a separate concave diffusion member 52 is formed on the inner side of the diffusion member 50 so as to be adjacent to the LED module 21 by double injection molding. As shown in FIG.
