  The present invention relates to an outdoor light-emitting diode illuminator and its shell apparatus, and more particularly to an outdoor light-emitting diode illuminator having high heat dissipation and a shell apparatus thereof.

  Light emitting diodes have advantages such as power saving, environmental protection, high brightness, and long service life, and are already replacing conventional illumination light sources. Applications using light-emitting diodes as light sources have also been proposed in the field of outdoor lighting equipment such as street lamps.

Therefore, it is necessary to further improve the heat dissipation function of the lighting device so as not to lower the brightness. In addition, since the streetlight is installed outdoors and receives sunlight during the daytime, thermal energy is accumulated in the shell and the space inside the shell, which affects the light emission efficiency of the light emitting diode.

The light emitting diode lamp set 3 is installed on the inner surface of the shell portion 41, and the heat energy generated by the light emitting diode lamp set 3 is conducted to the outside of the accommodation space 21 by the shell portion 41 and the heat radiating fins 42, thereby improving the heat radiation speed. can do.

  The light shielding plate 6 is installed on the shell body portion 41 and includes a plate body 61 and a plurality of fixing members 62. The plate body 61 is best made of a material having a heat insulating effect, and may be a single material or may be a plate material provided with a heat insulating layer (not shown). The heat insulating layer is made of, for example, sponge or polystyrene foam. A sandwiching layer made of a material can be used to enhance the light shielding and heat insulating effect. The fixing member 62 is connected between the plate body 61 and the shell body portion 41, and can fix the plate body 61 on the shell body portion 41, and is fixed to the upper ends of the plate body 61 and the equal heat radiation fins 42. Keep the distance of.

  The area of the plate body 61 is larger than the maximum cross-sectional area of the upper shell body 4, and the upper shell body 4 is located within the normal projection range of the plate body 61, and when the plate body 61 is fixed to the shell body portion 41, The sunlight directly hitting the upper shell 4 can be completely shielded, the temperature of the housing space 21 is lowered, and the ambient temperature of the light-emitting diode lamp set 3 is lowered to reduce the temperature of the upper shell 4 and the housing space. The influence on the light emitting function of the light emitting diode 31 due to the thermal energy stored in 21 can be reduced.

The heat energy is absorbed and heated to form hot air, and since the plate body 61 is located above the radiation fins 42, it is uniformly distributed in the area interposed between the plate body 61 and the radiation fins 42. The formed hot air is easily formed, and the cooled air can be sucked and quickly flowed in. Further, the radiating fins 42 are arranged in parallel, and the cooled air can enter the hot air area along the arrangement direction of the radiating fins 42 and generate convection with the hot air. That is, the radiating fins 42 and the plate bodies 61 are combined with each other to form a plurality of air passages 7, and the cooled air and the hot air are convected in the air passage 7 to accelerate the flow of the hot air to release the heat.
