The present invention relates to a diffusion cover for a downlight, and more particularly, to be easily fastened to the downlight, to prevent glare from being generated by the light emitted from the downlight, to improve illuminance, and to block ultraviolet rays. The present invention relates to a diffusion cover for downlights.

Down light, one of lighting devices, is a lighting method that drills a small hole in a ceiling and embeds a light source therein, and is the most widely used method of architectural lighting that integrates lighting and buildings. This type of downlight is buried, so there is almost no exposure of the lighting fixtures. In addition, the ceiling is dark, which makes it an ideal way to create an atmosphere of indoor space.

In general, the down light is installed on the ceiling or wall surface of the room to illuminate the room, but in recent years, as the concept of the light is changed in various ways, it is installed in the room to decorate the room in addition to its original purpose to illuminate the darkness. It is considered as a field of interior for enhancing effect and aesthetics, and is being developed and constructed in a suitable form.

In particular, the downlight, which is constructed for interior purposes in addition to the lighting, is widely used as a downlight tube having a reflection shade main body to create a unique indoor atmosphere.

Looking at an example of a conventional general configuration of such a downlight, as shown in Figure 1 of the accompanying drawings.

The down light 100 is provided with an upper and lower light fallopian fallopian tube-shaped reflector 150 which is narrow in the upper part and gradually opens in the lower part of the cylindrical case 110 in which the lower part is opened. The socket 160 is fastened to an inner upper end of the case 110 by a separate bolt, and the lamp 180 is detachably coupled to the socket 160 to be positioned in the reflection shade 150. At this time, the reflection shade 150 is supported by the elastic piece 130 protruding inside the ring-shaped frame 120. In addition, the ring-shaped cover 140 is provided at the lower portion of the ring-shaped frame 120 to prevent foreign substances from flowing between the ring-shaped frame 120 and the reflection shade 150.

In addition, the ballast 170 is fastened by bolts on the upper surface of the case 110, and at one side of the ballast 170, related parts such as terminals are fixedly installed.

Therefore, the down light 100 is coupled to the reflection shade 150 from the lower portion of the case 110 in the state in which the case 110 is embedded to be embedded in the ceiling 200, the socket 160 There is to install and use the bulb lamp 180 combined.

However, these downlights open the front part of the reflector, which is an essential part, and when the light emitted from the lamp is directly irradiated on the user, the user can not see for a moment by glare and blindness and can identify the object of caution properly. There is a problem that there is no. In addition, dust or foreign matter on the floor is attached to the reflector and lamp surface of the down light on the ceiling to contaminate the reflector and the lamp, reducing the lighting and interior effects, and also reduces the amount of light irradiated to the object. There is a problem that reduces the sense of beauty. In addition, as the front portion of the reflector is opened, there is a problem that the lamp is damaged when the user carelessly. And when the lamp is broken, there is a problem that a person located below the down light may be injured by the fragments of the lamp.

Proposed to solve this problem to some extent, Korean Unexamined Patent Publication No. 2002-0063416 (published on August 3, 2002) discloses a ceiling-mounted luminaire.

This is done by combining the reflector with the front opening of the reflector and dispersing the light emitted from the lamp located inside the lamp to protect the view caused by indirect lighting and to block the inflow of foreign substances. It is configured to do so.

However, such a ceiling-mounted luminaire has a problem that the reflector body and the reflector are integrally formed so that the existing reflector cannot be used.

Therefore, there is a demand for the development of an economical protection mechanism that can be used for the reflection shade body, which is used previously, and can be easily installed on an existing down light without a separate fastening device to prevent glare.

Therefore, an object of the present invention can be connected to the downlight without a separate fastening device, such as screws, can be used for various types of downlight irrespective of the type of the downlight, by spreading the light emitted from the lamp of the downlight It is to provide a diffusion cover that can provide a soft light to the user.

Another object of the present invention is not only to block ultraviolet rays emitted from the downlight, to improve illumination, to prevent dust from adhering, but also to prevent insects from gathering by generating a wavelength of light that insects dislike. To provide a cover.

In order to achieve the above object of the present invention, the present invention is a circular main body in contact with the front opening of the downlight is inserted into the lamp to diffuse the light emitted from the lamp to generate a glare phenomenon by the light; And a fastening means formed of a vertical portion protruding upward from an outer circumferential surface of the main body and a bent portion bent in the direction of the down light at the distal end of the vertical portion.

The use of the diffusion cover according to the present invention not only blocks dust or foreign matter flowing through the front opening of the downlight reflector, but also prevents dust from adhering to the diffusion cover itself, thereby preventing inconvenience due to light deterioration and cleaning of the lamp. can do.

In addition, unlike the diffusion cover formed of glass, it uses only recyclable materials such as PET, which is inexpensive, and does not require a separate screw or piece coupling device, so it can be tightened by inserting only. It can be used for various types of downlights. In addition, the diffusion cover does not hinder aesthetics caused by discoloration such as yellowing even after long-term use, and prevents a user from being injured by using a material that does not break even if it falls, unlike a diffusion cover formed of glass.

In addition, the diffusion cover is easily and firmly installed on the already installed down light to diffuse the light, thereby preventing the occurrence of glare caused by the down light. In particular, the recently spotlighted LED has a glare because it is straight, but can solve the occurrence of glare through the diffusion cover of the present invention.

In addition, the diffusion cover may improve the illuminance of the light to reduce the amount of light used per unit area. In this case, the illuminance is improved by about 15% on average, thereby saving the use of the overall energy.

In addition, the diffusion cover may block about 99% or more of ultraviolet rays emitted from the lamp of the down light. Furthermore, the diffusion cover may prevent the insects from gathering in the diffusion cover by changing the wavelength of the light emitted from the lamp to the wavelength of the light that the insect dislikes.
