[Prior Art] Since the light-emitting diode has the advantages of power saving, environmental protection, high brightness, and long service life, it has gradually replaced the traditional illumination source. In the field of outdoor lighting, such as street lamps, applications using light-emitting diodes as light sources have also been proposed. Referring to FIG. 1 , a street lamp generally using a light-emitting diode as a light source mainly includes an upper casing 91 , a light-transmitting cover 92 , and a chamber 93 formed by the upper casing 91 and the cover 92 . Light emitting diode array 94. Although the light-emitting diode has the above advantages, a large amount of heat energy is generated when the light-emitting diode emits light, especially a high-power light-emitting diode, and it is more necessary to improve the heat dissipation performance of the lamp to avoid excessive heat energy accumulation and cause the light-emitting diode. The luminous efficiency and service life of the body are reduced. Moreover, because the street light is set outdoors, it is exposed to sunlight during the daytime, and the space inside the lamp housing and the lamp housing also stores thermal energy, which affects the luminous efficiency of the light-emitting diode. [New content] Therefore, the object of the present invention is to provide a lamp housing device for an outdoor light-emitting diode lamp which can reduce the heat energy storage generated by sunlight irradiation and can increase the flow of hot air with high heat dissipation.

The sun visor is disposed on an outer surface of the upper casing, and includes a plate body and a plurality of fixing members connected between the plate body and the upper casing, and the plate body and the upper casing The body has a separation distance. The sun visor shields the sunlight from direct sunlight to the upper casing, and reduces thermal energy stored in the upper casing and the chamber. Moreover, the sun visor cooperates with the upper body to accelerate the flow of hot air and greatly increase the heat dissipation rate. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments of the drawings. Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals.

The upper body 4 includes a casing portion 41 and a plurality of heat radiating fins 42 formed on the outer surface of the casing portion 41. The cover 5 cooperates with the housing portion 41 to form a chamber 21 for accommodating the light-emitting diode lamp set 3.

The plate body 61 is preferably made of a material having a heat insulating effect, and may be a single material, or a plate having a temperature-insulating layer (not shown) may be used. The temperature-insulating layer may be, for example, foam, styrofoam or the like. The sandwich is made to add the effect of shading and heat insulation. The fixing member 62 is connected between the plate body and the casing portion 41, and the plate body 61 is fixed to the casing portion 41, and the plate body 61 is spaced apart from the top end of the heat dissipation fins 42. The area of the plate body 61 is larger than the maximum cross-sectional area of the upper casing 4, and the upper casing 4 is located within the orthographic projection range of the plate body 61. The plate body 61 is fixed to the casing portion and the full blockage is 70. The sunlight is irradiated to the upper casing 4' to lower the temperature of the ^^.- to 21, which can also reduce the temperature of the light-emitting diode lamp set 3 = daytime, and can reduce the heat energy stored in the upper shell. The luminous efficacy of the body 4 and the inner and outer ringing light-emitting diodes 31. When the hair is used at night: the body 31 is illuminated, the heat generated by the light-emitting diode 31 can be conducted by the body 41 and the heat-dissipating fins 42, and is located in the heat-dissipating manner, and can be absorbed and transmitted to the heat-dissipating fins 42. The heat energy is heated to be formed so as to be interposed between the plate body and the heat dissipating fins 42. The area between the eight cloths and the heat dissipating fins 42 is relatively easy to form a uniform f> The heart "Γ' can quickly attract cold air to flow, and in addition, the two are arranged in parallel, and the cold air can enter the hot air region along the fine σ to convect with the hot air. 7 M323576 That is, the heat dissipating fins 42 cooperate with the plate body 61 to form a plurality of air ducts 7, and the cold and hot air convect in the air duct 7, thereby accelerating the flow of the hot air and greatly increasing the heat dissipation rate. The LED array 3 includes an array of LEDs 3 1 and a circuit board 32. The assembly of the LED unit 2 can be accomplished by using the existing technology of assembling the LEDs, and the LEDs 3 are It is better to have high power. The light-emitting diode lamp of the present invention is suitable for being combined with a light pole (not shown), and can be externally connected with a power source for providing outdoor illumination. Moreover, the technology of combining the light-emitting diode lamp 1 with the lamp pole is not the present invention. The focus can be achieved by referring to existing technologies', and will not be described in detail here. Referring to FIG. 4 and FIG. 5, a second preferred embodiment of the present invention relates to a lamp housing device for an outdoor light-emitting diode lamp having high heat dissipation and a light-emitting diode lamp having the lamp housing device. The second preferred embodiment is substantially the same as the first preferred embodiment. However, the upper housing 4 of the second preferred embodiment has no heat dissipation fins and is coated with high thermal conductivity on the inner and outer surfaces of the upper housing 4'. The coating is applied to increase the heat dissipation rate of the upper casing 4'. Moreover, the plate body 61 of the sun visor 6 has a distance from the upper casing 4', so that the area between the plate body 61 and the upper casing 4 is relatively easy to form a uniformly distributed hot air, and can quickly attract cold air. The inflow "forms the convection of cold and hot air, so it can accelerate the flow of hot air, which can greatly increase the heat dissipation rate. Referring to Figures 6 and 7', a second embodiment of a light-emitting diode device having a high-heat-dissipating outdoor light-emitting diode lamp is used. The third preferred embodiment is substantially identical to the resident member of the second preferred embodiment. The plate 61 of the sun visor 6 has a circumference of M323576 1 and a plurality of intermediate portions of the plate 61' are formed. In the gate hole 611, there is a diagonal slab 612 in the middle of the B 611 so that sunlight cannot be directly transmitted to the upper casing 4", but hot air formed between the plate body 61 and the upper casing 4 can be diffused through the gate hole 611. That is, between the plate body 61 and the upper casing 4", hot air rolling can be formed, which can quickly attract cold air to flow in, and squeeze the hot air to rise, and then pass through the grid hole. 6丨丨 diffuses into the atmosphere to accelerate the diffusion of hot air. • The above-mentioned lamp housing device can shield the sunlight from the upper housing by the sun visor to reduce the ambient temperature of the light-emitting diode lamp group during the daytime, and can prevent thermal energy from being stored in the upper casing and the chamber. In the middle, it affects the luminous efficiency of the light-emitting diode. Moreover, the sun visor cooperates with the upper casing to accelerate the flow of hot air and greatly increase the heat dissipation rate. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent change and modification made by the novel patent application scope and the novel description content, All are still within the scope of this new patent.
