Description

An indirectness lighting lamp which uses the led}

The present invention relates to an indirect lighting, and more particularly, to improve the structure of the lighting lamp to perform the light emitting function from the direct lighting method using the existing LED to the indirect lighting method using the light diffusing unit and at the same time transparent installation arrangement of the light diffusing unit Designed to be suitable for lighting lamps in the tube, the use of LEDs for light emission can be minimized to prevent overheating of the lighting lamp due to LED heating in the transparent tube and to prevent damage and malfunction of the lighting lamp. It relates to an indirect lighting lamp using the LED.

In general, lighting fixtures are widely used not only in living spaces such as houses and buildings, but also in workspaces such as workplaces, shops, and showcases.

Lamps applied to the luminaire are generally used fluorescent lamps or incandescent lamps. However, such a fluorescent lamp or an incandescent lamp consumes a lot of power and has a problem in that a large number of lamps need to be installed to illuminate a large place because the light is also weak.

Accordingly, the development of lighting fixtures using LEDs (Light Emitting Diodes) with high luminous efficiency is minimized, and the power consumption is minimized.

Compared with conventional light sources, these LEDs are not only compact and have a long lifespan, but also have low power consumption due to the direct conversion of electrical energy into light energy, resulting in high energy efficiency and high-speed response characteristics. Will be.

However, LEDs are very glare because of the straightness of light from one point, so it is very difficult to use them as general lighting fixtures. there was.

In order to solve this problem, luminaires that allow LEDs to be indirectly irradiated without emitting light are being released.

It is configured to include.

Accordingly, when power is applied to the circuit board 70 from the power supply device 80, the LED lamp 20 emits light, and the emitted light is emitted to the outside through the light reflecting plate 30.

However, the conventional indirect lighting equipment using the LED structure having such a structure has a great difficulty to popularize at the present time.

In other words, the lamps that are currently used are mainly made of fluorescent lamps, so from the user's point of view, replacing them with LED lighting devices using energy efficiency only requires high construction costs in a short period of time rather than gains from improving energy efficiency. The burden was higher.
