Generally, LED (Light Emitting Diode) has a high luminous efficiency and a long life span as compared with conventional light sources, and is currently rapidly replacing existing light sources.

However, since the LED used as the light source of the LED luminaire is a semiconductor device, it is necessary to maintain the junction temperature inside the device at a certain temperature, that is, below 85 deg. It is important to make a heat dissipation structure capable of maintaining the luminous efficiency and lifetime of the LED by sufficiently dissipating the heat generated during the operation of the LED to the outside, because it is possible to maintain the long lifetime of the LED (about 50,000 hours) Do.

However, in view of the fact that HID (High Intensity Discharge) lamps and sodium lamps, which are conventionally used as high-cost light sources, are mainly used for high ceiling lamps used in warehouses and factories, introduction of LED lamps having improved heat- Is necessary.

Meanwhile, in a conventional LED lamp with a built-in converter, the heat of the LEDs transferred to the LED substrate is brought into surface contact with the heat-conducting tape or the heat-dissipating adhesive tape to transfer the heat to the heat-radiating structure formed of an aluminum die- And the heat is radiated to the atmosphere through the heat radiation surface exposed to the heat radiation surface.

As a related art related to this, Korean Registered Utility Model No. 20-0470636 (Dec. 24, 2013) discloses "LED lamp with built-in converter for high ceiling lighting ".

However, the LED lamp with built-in converter for high ceiling lighting according to the related art is incompatible with the converter case 5, which requires additional cost in installation.

When the LED is used in a high ceiling of 5M or more, the height of the LED lamp can not be adjusted and the LED lamp can not be used efficiently. Therefore, an additional LED lamp must be installed in order to adjust the illuminance.

In addition, the heat dissipating fin 6 of the LED lamp according to the related art has a problem in that when the number of LEDs constituting the LED module is increased, the size increases according to the number of LEDs and the weight becomes heavy, .
