The present invention relates to a light emitting device, and more particularly, to a light emitting device having a structure that is easy to assemble and easy to use for interior lighting.
Recently, as the light emitting diode (LED) is known to have a structure that emits white light by applying a phosphor, its application range has been extended to a lighting field that can replace a conventional light lamp in addition to a simple light emitting display function. . In addition, research on high power light emitting diodes suitable for lighting has been continuously conducted.
The light emitting diode, which is one of the semiconductor devices, decreases its lifespan and decreases the luminous efficiency when the temperature rises above the rated operating temperature. Therefore, in order to increase the output of the light emitting diodes, the light emitting diodes effectively emit heat generated from the light emitting diodes. Heat dissipation structure is required.
However, the conventional light emitting diode has a structure in which a lead pin on which a light emitting diode chip is mounted is molded with a plastic material. The light emitting diode having such a structure is difficult to be applied to a high output light emitting diode because the heat dissipation is low because the heat is radiated through the lead pins.
In order to improve such a problem, various packages having a structure capable of mounting a high output light emitting diode chip and improving heat dissipation efficiency have been proposed.
On the other hand, halogen lamps are widely used for indoor and outdoor interiors. By the way, halogen lamps have a rated power consumption of about 50 watts, resulting in high power consumption and high heat generation. In addition, the halogen lamp has a disadvantage that the range of use is limited because the merchandise is deteriorated by the heat generated when installed as a showcase lighting. In addition, the halogen lamp has a short lifespan of about 5,000 to 6,000 hours, so there are frequent disadvantages of replacement, and since the illumination light is a single color, there is a problem in that it cannot be used for lighting effects of various colors.
In order to improve such a problem, an interior light emitting device using a high power light emitting diode has been disclosed in Korean Laid-Open Patent No. 2004-0037523.
However, the light emitting device has a structure in which the light emitting diode assembly can be mounted on the upper part of the opening of the aluminum shade which is open at the top, and the process of drawing out the wire along the inner flow path that is to be extended to the lower portion of the aluminum shade is cumbersome, It is not a structure that can directly transfer heat from the diode to the aluminum shade has a disadvantage in that the heat dissipation efficiency is low.
The present invention has been made to improve the above problems, and an object of the present invention is to provide a light emitting device that is easy to assemble and disassemble a light emitting diode and to increase heat dissipation efficiency.
In order to achieve the above object, the light emitting device according to the present invention has a body portion having an upper receiving groove formed therein, and a lower portion of the body portion having ribs protruding outward from the body portion to extend the heat dissipation material.

Preferably, the main heat dissipation body has a plurality of inlet grooves drawn along the outer circumferential surface of the main heat dissipation body to be spaced apart from each other in the vertical direction.
In addition, the first internal flow path of the main heat dissipation body is formed below a predetermined distance from the top of the main heat dissipation body, the inclined surface inclined to gradually narrow the inner diameter from the top of the main heat dissipation body to the first internal flow path It is further provided.
More preferably, a third screw line is formed in the second internal flow path of the sub heat dissipation body.
