Generally, a security light fixture (or a street light fixture) is installed at regular intervals along a roadway, a square, a park, a housing complex, a factory complex, or the like, and illuminates the surrounding area at night. In recent years, And durability of the LEDs are also disclosed. That is, LEDs have been applied in various industrial fields. Particularly, a luminaire with a high-brightness LED is advantageous in that the lifetime is semi-permanent and the power consumption is very low. In recent years, a variety of LED lighting devices (lighting devices) have been developed to be used in various environments in various environments and are applied to various places. In particular, in a field requiring a high luminance light source for a long time such as a security lamp, a street lamp, Demand is also increasing.

However, since the conventional LED lamp that requires a high-brightness light source for a long time as described above is a structure in which a circuit board on which a high-brightness LED is mounted through a housing having a certain shape is applied, the use of an LED lamp in an environment requiring a high light source There is a drawback in that a heat dissipation housing having various sizes must be separately manufactured in accordance with an LED circuit board which adds a plurality of LED circuit boards or provides a predetermined light source.
