Description

Diffuse cap to improve the illuminance of the lamp {REFLECTION CAP FOR IMPROVING ILLUMINATION OF ELECTRIC LAMP}

The present invention relates to a diffusion cap that improves the illuminance of a light, and more particularly, to insert a light to improve the light intensity of the light, as well as a diffusion that can solve a problem such as a decrease in durability of the light generated in a humid environment. It is about a cap.

Lamps, including fluorescent lamps, are installed in not only ordinary households, but also in large-scale sales facilities such as food refrigerators, crop house-growing plastic houses, department stores and discount stores, as well as enhancing the merchandise by making products on display look fresh. Role. These lamps vary in capacity (thickness or length), but are widely used at 60 cm. There are fluorescent lamps such as 90Cm and 120Cm, and recently, a device that can be used by mounting an LED to an existing fluorescent lamp socket is also used.

In the case of such fluorescent lamps, the amount of illuminance to be emitted is determined, and the number of fluorescent lamps to be installed is determined according to the area of the space to be installed. When the fluorescent lamps are installed in a large space, a plurality of fluorescent lamps are required. This is consumed. In addition, when installed in a food refrigerator in a humid environment in order to stimulate the consumer's desire to make the food look fresh, or when used in a plastic house where water is sprayed for crop cultivation, durability may be reduced due to moisture or a short circuit. It can also cause safety problems.

In order to solve this problem, techniques have been developed to improve the illuminance emitted from one fluorescent lamp to reduce the number of fluorescent lamps installed in a predetermined space or to obtain higher illuminance even if the same number of fluorescent lamps are installed. .

For example, "Fluorescent lamp reflector" is disclosed in Korean Utility Model Publication No. 20-0156365 (registered June 12, 1999).

The present invention relates to a fluorescent lamp reflector which improves the reflection efficiency of light emitted from a fluorescent lamp through the configuration of the first reflector and the second reflector, thereby improving the brightness of the fluorescent lamp.

However, this technology can improve the brightness of the light to some extent by reflecting the light emitted in the opposite direction of the light through the reflector, but in terms of efficiency of improving the light through the reflector The problem is that there are limitations.

In addition, Korean Utility Model Publication No. 20-0179621 (registered on February 11, 2000) discloses a high efficiency lamp reflector.

This relates to a high efficiency lamp reflector which has a large radius curved surface extending from the vicinity of the lamp to the outside to increase the reflection efficiency and to maintain brighter illumination by preventing the lights of the two lamps from colliding with each other.

However, this technology can be expected to improve the illuminance to some extent to improve the illuminance by reflecting the light emitted from the light through the reflector, but this also has a problem that can not be expected to greatly improve the illuminance of the light through the reflector.

In case of the above-mentioned prior art, there is a problem in that the light emitted from the light is reflected through the inclined surface of the reflector to limit the illuminance. Therefore, a technology capable of improving the illuminance of the light through the reflector is higher. Developed.

For example, Korean Unexamined Patent Publication No. 10-2008-0065951 (published on July 15, 2008) discloses a light fixture having improved reflection efficiency by expanding a reflecting surface.

This is to form the entire surface or part of the reflecting surface of the light fixture main body in the form of zigzag irregularities, but to form a large number of intaglio or embossed embossing on each uneven surface to increase the diffuse reflectance, and also to reflect the reflection surface inside the light fixture body The present invention relates to a light fixture having an improved reflection efficiency by installing a reflection shade in the form of zigzag irregularities, and forming a plurality of intaglio or embossings on each of the irregularities of each reflection shade to increase diffuse reflectance.

However, in the case of this technique, by forming a plurality of intaglio or embossing on each uneven surface of the reflection shade, it is possible to expect the light intensity of the electric light to be improved to some extent compared to the above-described prior art, but only by reflecting the light There is still a problem with its limitations.

All of the prior art techniques for improving the illuminance of electric light using the reflection shade mentioned above have their limitations in improving the illuminance of the electric light through only the reflection shade.

In addition, the reflection shade for improving the illuminance of the light has a structure that is integrally formed with the light fixture main body, and different light fixture main body (for example, the body such as hanging, the body of the wall, etc.) There is a problem that cannot be used.

In addition to improving the illuminance of the lamp, it can be easily installed in various kinds of lamps (hanging lights, wall lights, landfill lamps, etc.) and used safely in a humid environment. In addition to preventing skin aging of people working in this installed environment, the development of economical reflectors that can prevent discoloration or deterioration of food and display products is required.

Therefore, an object of the present invention is to use a diffusion cap that can be used for a variety of existing fluorescent lamps or LED lights regardless of the type of the lamp shade, the presence or absence of the lamp shade connected to the building wall, desk, etc. to improve the illuminance of the lamp To provide.

In order to achieve the above object of the present invention, the present invention is provided between the first seat portion fitted to the lamp lamp to improve the illuminance of the lamp, and between the first seat portion and the lamp lamp to emit light from the lamp lamp. Provided is a diffusion cap for improving the illuminance of a light including a second sheet portion reflecting the reflected light.

The diffusion cap may further include a pair of finishing portions covering both side surfaces of the lamp lamp inserted into the first seat portion and having a through groove formed therein so that the lamp lamp terminal pins penetrate therein.

Diffusion cap to improve the illuminance of the light according to the present invention is simple and robust to general lighting, lighting of food refrigerators used to make food look fresh, lighting used for lighting such as plastic house used for crop cultivation. By installing and reflecting and diffusing the light lost to the back of the lamp, improved illumination can be expected. In addition, the diffusion cap can block the water flowing into the lamp to prevent a short circuit occurring in a humid environment such as a vinyl house.

As such, it is possible to expect the improvement of illuminance, thereby reducing the use of lighting fixtures per unit area, thereby reducing power consumption, contributing to the prevention of global warming, and providing individual users with the energy savings. The carbon mileage will be paid and used. In addition, the position of the reflection sheet for the reflection of light can be adjusted to adjust the direction of light irradiation and various illumination outputs are possible.

In addition, the diffusion cap does not inhibit the appearance of the discoloration, such as yellowing phenomenon even long-term use, it can prevent the occurrence of glare caused by the lamp. In particular, a light-emitting lamp equipped with a recently spotlighted LED lamp has a straightness to cause glare, it is possible to solve the occurrence of glare through the diffusion cap of the present invention. In addition, it not only blocks dust or foreign matter attached to the surface of the lamp but also prevents dust from adhering to the diffusion cap itself, thereby preventing inconvenience caused by light deterioration and cleaning.

In addition, by changing the near-ultraviolet rays of 340 to 350nm, the wavelength of light emitted from the electric light to the wavelength of light that insects dislike, the phenomenon of insect gathering and discoloration of clothing, books, photos, pictures, etc. It prevents discoloration and deterioration and makes the food look fresh. Furthermore, the diffusion cap can prevent the skin aging, skin disease, eye fatigue of the user by blocking the near-ultraviolet rays generated from the lights, thereby improving the working environment of people working in places where the lights are used a lot. Can be.

In addition, unlike the diffusion cover formed of glass, since it uses only recyclable materials such as PET, it is inexpensive and is made of recyclable material without using harmful chemicals, thereby reducing environmental pollution. In addition, the diffusion cap does not need a separate screw or piece coupling device can be fastened only by inserting, the shape is not fixed can be used for various types of lamps, unlike the diffusion cover formed of glass Using materials that do not break even if they fall can prevent the user from being injured.
