One embodiment of the present invention relates to an LED lamp used for indoor and outdoor lighting, and more particularly, it is possible to easily assemble and separate the lens cover and the body, so that the assembly and maintenance work can be made easily. It relates to an LED lamp.

In general, the lamp is equipped with a lamp, such as an incandescent lamp, a fluorescent lamp, a mercury lamp, a halogen lamp, a sodium lamp as a light source, so that the adjacent area where the lamp is installed can be identified above a certain level of illuminance.

However, lamps having such a light source consume a lot of electricity and have a short service life, in particular, have high maintenance costs and pollute the environment.

Therefore, recently, in order to improve illuminance and save energy, LEDs having low power consumption and semi-permanent life characteristics have been applied as a light source of a luminaire. In addition, the lamp using the LED has the advantages of easy installation, low maintenance cost and excellent stability.

Usually, the LED lamp is a heat sink made of a metal having excellent thermal conductivity, an LED substrate mounted on one end of the heat sink and mounted with a plurality of LEDs, and a lens cover fixed to one side of the heat sink while covering the LED substrate.

On the other side of the heat sink, a plastic body including a screw base and the like is fixed. The body has a screw thread formed on its outer circumferential surface, and is fastened and fixed to a thread formed on the inner circumferential surface of the heat sink. An adhesive is applied between the inner circumferential surface of the sieve and the outer circumferential surface of the body so as to be adhesively fixed.

However, when assembling the lens cover and the main body to the heat dissipating method by screwing, there was a problem in that the assembly process takes a lot of time and productivity is lowered. In addition, in order to process the thread, there is a problem in that a molding process for this is added or a mold having a very complicated structure is required, thereby increasing the manufacturing cost. In addition, even if the process is not added or the complicated mold is used, if the threads are not matched, the lens cover or the main body may not be fastened to the heat sink and rotate freely. there was.

In the case of using an adhesive to solve this problem, there is a problem that it is practically impossible for the operator to separate these components from the heat sink without damaging the lens cover or the body when maintenance of the LED lamp is required.

One embodiment of the present invention is to provide an LED lamp that can be easily assembled and separated, such as the lens cover and the main body without the use of adhesives to facilitate the assembly and maintenance work. .

In order to achieve the above object, the LED lamp according to an embodiment of the present invention, a cylindrical radiator made of metal and formed with one or more fins on the outer circumferential surface, mounted on one end of the radiator and multiple LED board mounted with the LED, the lens cover is fixed to one side of the heat sink by the locking means while covering the LED board, the power substrate spaced apart from the LED board and installed in the heat sink, and the heat sink Coupled to the other side by the insertion means characterized in that it comprises a main body installed with a screw base.

As described above, according to an embodiment of the present invention, the lens cover having the locking means and the main body having the insertion means are fixed to the radiator, so that the assembling operation is simplified and the components are separated without maintenance during maintenance. There is an effect that the maintenance work can be done easily.
