LED Lighting Lamp {LED Illumination Lamp}

The present invention relates to an LED lamp that can enhance the aesthetics by directly illuminating the light directed to a variety of objects such as bridges, buildings, etc. More specifically, excellent directing effect of the light emitted from each LED, natural convection And it is possible to achieve an excellent heat dissipation effect by the ventilation method, to save power, and to a compact LED lighting lamp with a compact appearance.

In general, various types of lamps are used to provide light or illuminate an object at night or indoors. Such lamps are powered by converting electrical energy into light energy to provide light or irradiate an object, and generally use an incandescent lamp or a fluorescent lamp.

Recently, a lamp using LED (Light Emitting Diode) has been proposed and widely used due to the advantages of low power consumption and various color outputs despite being expensive. However, such an LED lamp has a problem that its efficiency decreases due to heat generation when used for a certain time, and in the long term use, the amount of heat is eventually increased to shorten its lifespan.

On the other hand, techniques for preventing the shortening of the life due to such long-term use and excessive heat is proposed, as one example there is a Utility Model Registration No. 20-0336197.

In particular, the heat released through the lower portion of the cover 30 is formed in the lower portion of the cover 30 and the outside air is circulated to the air passage 34 communicating with the space between the respective heat radiation fins 14 to effectively release the heat. In addition, the heat discharged through the main body 10 is not only a heat dissipation action of each of the heat dissipation fins 14, but also the outside air is introduced into the circulation through the vent 16 formed on the side of the support piece 13 to circulate It can effectively release heat.

Of course, the overall height or thickness of the lamp can be installed in a variety of ways in a variety of locations, by using a relatively low power LED can reduce the electricity bill. In particular, it is possible to significantly reduce the power consumption by eliminating the separate electric drive heat radiation means.

In addition, the translucent color output unit 31 of the cover 30 can perform a variety of color output by harmonizing light when the LED 22 emits light, while the LED 22 is turned off when the LED 22 is turned off The image is not exposed to the outside, so you can maintain a clean aesthetic.

As described above, according to the LED lamp according to the present invention, through the translucent color emitting portion of the cover can harmonize the emission color of the LED to provide a variety of color output, the natural circulation method heat without installing a separate cooling means Can extend the lifespan, and the LED and the internal components are not exposed to the outside through the cover to keep the appearance clean, and do not use a separate heat dissipation means can save power, The overall appearance has a compact effect.
