LEDs (Light Emitting Diodes) have longer lifespans than conventional light sources, and because electrical energy is directly converted into light energy, they consume less power, emit high brightness with high energy efficiency, and have high-speed response characteristics. Luminaires using light sources have been developed in various ways from general home use to vehicle use and outdoor use.

In general, a street lamp, which is one of outdoor lighting fixtures, is usually provided with an outer casing on a support having at least one arm in the form of a memory or a T, and a lamp is installed in the outer casing.

The outer casing 3 of the street lamp is provided with a threaded socket 3a and forms an inner space for protecting the lamp from wind and rain (see FIGS. 2 and 4).

The size of can be arbitrarily extended.

That is, in the outdoor LED lamp in which the prefabricated heat dissipation fins 33 are not assembled, the size of the heat dissipation fins is achieved by rotating coupling of the outer casing 3 to the threaded socket 3a regardless of the size of the prefabricated heat dissipation fins 33. It can be freely formed free from the space constraints of the outer casing of the street lamp, so that the heat radiation performance can be arbitrarily increased.

In addition, the prefabricated heat dissipation fin 33 is formed of a wire coil type heat dissipation fin 331, so that the heat dissipation surface area to prevent air congestion is significantly widened, and the wire coil type heat dissipation fin is radiated from the light source by being exposed to a space where natural ventilation occurs.

In addition, after the outdoor LED lamp is coupled to the outer casing screw-type socket (3a), the LED lamp irradiation direction should be adjusted, but the holder 60 of the spline key coupling structure for the casing coupling member 50 is for this time.

That is, the rotation of the holder 60 is prevented by coupling the spline keys 531 and 631 to the casing coupling member 50 so that the lamp irradiation direction is fixed, and the irradiation direction of the lamp is adjusted from the casing coupling member 50. When pulling out the holder 60, the spline key 631 of the holder comes out of the spline key 531 on the casing coupling member side, and the holder is free to rotate, so adjust the irradiation direction and leave the holder 60 as it is after adjusting the direction. The key is coupled again by the return force of the main surface elastic member 1 (71) so that the irradiation direction of the lamp is very simply adjusted and fixed.

In addition, the configuration including the clutch portion 64 and the variable clutch portion 314 (see FIGS. 13 to 15) is configured such that the spline key is replaced by a clutch type key shape, and the main bolt 67 at the angle adjustment. When the part is released, the variable clutch portion 314 of the heat dissipation means body 31 side withdraws itself from the clutch portion 64 of the holder 60 by the elasticity of the elastic member 2 (72). Since the main bolt 67 is re-fastened as it is possible after the adjustment, the angle adjustment is made more convenient than the spline key structure.
