3 to 6, the lighting apparatus of the present invention includes a main body housing 120 and a receptacle connecting device detachably connected to the main body housing 120.

In the body housing 120, the length in the x- and y-axis directions is much longer than the thickness in the z-axis direction. Therefore, the body housing 120 has a relatively thin and wide structure.

The body housing 120 is made of an insulating material such as plastic. Metal plates on which a plurality of LEDs 100 used as light sources are mounted on the front surface of the main body housing 120 are assembled. Heat dissipation holes are formed on the side and rear of the main body housing 120. The metal plates 30 are low-cost metals that do not include a resin layer therein, such as a metal printed circuit board (PCB) as described below. The LEDs 100 are soldered directly to a metal plate or glued through Ag epoxy.

An insulating sheet having a circuit pattern is bonded to the surface of each of the metal plates 30, and the LEDs 100 are exposed through openings formed in the insulating sheet. Due to the high heat dissipation characteristics of the metal plates 30, the metal PCB, a motor fan, a heat sink, and the like, which are generally used for heat dissipating LEDs, do not need to be separately installed in the body housing 120. . Therefore, the lighting device of the present invention can effectively heat dissipate the LEDs 100 without expensive components, so that the lighting device can be made smaller and lighter than conventional LED lighting devices, and can significantly reduce the cost. The heat dissipation structure through direct bonding of the LED and the metal plate is described in detail in Korean Patent Application No. 10-2010-0025801 (2010. 03. 23) and Korean Patent Application No. 10-2011-0016927 (2011. 02. 25) filed by the present applicant. Since it is described, a description of the structure will be omitted.

Each of the metal plates 30 is assembled to the body housing 120 at different angles so that light emitted from the LEDs 100 can be irradiated at a wide angle. Bosses protruding toward the front side are formed on the rear surface of the main body housing 120, and the metal plates 30 are fixed to the front side of the main body housing 120 by screws fitted to the bosses. .
