Description

LED Floodlight {SEARCH LIGHT USING LED}

The present invention relates to a light emitting device using an LED, and more particularly, it is possible to make the illuminance of light irradiated from a plurality of light emitting diodes uniform, to improve the reflection efficiency, and to excellently extend the life of the LED due to excellent heat dissipation characteristics. The present invention relates to a light-emitting transmitter using an LED which can fundamentally prevent the inflow of moisture to electrical and electronic components, thereby greatly reducing power demand and greatly extending the life.

In general, a light emitter is a lighting device for irradiating light of a desired brightness to a relatively large place indoors or outdoors, and is installed outside of them so as to illuminate an architectural structure, a memorial structure, and various stadiums.

Such a light emitter is relatively expensive because it has a structure capable of irradiating light of high brightness, and the structure is relatively complicated, so it is inappropriate to be applied to a small memorial structure or landscape lighting.

In view of this point, a light emitter using an LED (light emitting diode) has been proposed to be easily applied to a relatively small structure, landscape lighting, signboard, and the like.

Since the LED-based light emitter uses high brightness LEDs, a difference in luminance is generated between the LEDs and the LEDs, and thus, it is difficult to expect an effect such that light generated from each LED is irradiated with one light. There was a problem.

In view of these problems, Korean Patent Publication No. 2006-00217789 and Patent Publication No. 2005-0002714 have disclosed a lighting apparatus using a light splitting floodlight plate.

In addition, Utility Model Registration No. 0393988 discloses a light emitter having an improved heat dissipation effect.

However, since the above-described conventional light emitter uses a plurality of light emitting diodes, a core portion of light irradiated from each light emitting diode is dispersed, so that light of uniform illuminance cannot be irradiated.

In addition, when the LED used as a lamp of the floodlight is for high brightness, more heat is generated, but when it is not sufficiently cooled, the LED deteriorates and the life is greatly shortened.

The present invention is to solve the above problems, it is possible to uniformize the illuminance of the light irradiated from the plurality of light emitting diodes, improve the reflection efficiency, excellent heat dissipation characteristics, greatly extend the life of the LED, and The intention is to provide a floodlight using LEDs that can fundamentally prevent the inflow of moisture to electronic components, greatly reducing the power demand and extending the lifespan.
