However, the front end portion 2 of the lid body is designed to have a flat shape as shown in Fig. 5b or a sloped shape as shown in Fig. 5c, depending on the specific needs. The fan 4 is mounted in the accommodating groove 41 _ in the heat dissipation path 2 、 and is sandwiched between the cover 21 and the base 22 in a fixed manner. However, it is not limited thereto, and 'can also be locked to the air outlet 25 (as shown in Fig. 3) of the cover body 21 or the air outlet bracket by a connecting member 42 (e.g., a bolt) as shown in Fig. 6. Of course, the 201120369 fan can also be replaced by a chilled chestnut. The power supply 7 can be built in the heat dissipation passage 20 or can be installed in different installation forms and positions so as not to impede the heat dissipation of the LED light source element 3. However, it is not limited thereto, and it is also possible to separate the power supply 7 from the LED light source element 3. Referring to Figures 4 and 7, the LED light source element 3 includes a metal heat sink substrate 31 and a plurality of LED light emitting elements 32. The metal heat dissipation substrate 31 has an arc shape. The LED light emitting element 32 is mounted on and electrically connected to the metal heat sink substrate 31. The metal heat dissipating substrate 31 may be a flexible sheet made of a highly thermally conductive metal such as aluminum or copper, and a plurality of through holes 311 are disposed on the metal heat dissipating substrate 31. The thermal conductivity of the metal heat sink substrate is greater than 40 watts/meter* absolute temperature unit (W/MK). Since the curved bottom wall of the front end portion of the base 22 has a mounting portion 241 having an area corresponding to the area of the metal heat dissipation substrate 31, the metal heat dissipation substrate 31 is fixed to the mounting portion 241 of the base 22 by a buckle or a fastening member, and is covered with ventilation. The port 23 is simultaneously shaped and positioned by the curved strip 24 of the base 22 described above. The metal heat sink substrate 31 may have a bending radius of 10 mm to 100 mm. In addition, the LED light-emitting element 32 can be mounted in a structure as shown in FIG. 8 : a plurality of LED brackets 33 are used, and each LED bracket is respectively provided with a plurality of thermoelectric separation type LED light-emitting elements 32, and the LED bracket 33 is welded. Alternatively, it is fixed on the light source substrate 31 by gluing, and the LED light-emitting elements on the LED holder 33 are arranged to be staggered with the through holes 311 on the substrate 31. The LED holder 33 can also be soldered to the metal heat sink substrate 31 in a chip or plug type. The front surface, the reverse side, and the side thick portion of the metal heat dissipating substrate 31 form a 201120369 heat dissipation layer to ensure rapid elimination of heat generated by the LED light emitting element 32. Of course, the mounting of the LED light-emitting element 32 is not limited to the configuration shown in Fig. 8, and the LED light-emitting element 32 can also be directly molded out of the metal heat-dissipating substrate 31. Further, a metal heat dissipation layer or an alloy heat dissipation layer may be coated on the back surface of the metal heat dissipation substrate 31 to enhance the heat dissipation effect. Further, a heat sink, a heat pipe or a semiconductor cooling chip can be mounted in the heat dissipation channel 20 to achieve better heat dissipation. Further, referring to FIG. 3, the LED light source module may include an external power source lamp cap 5 and a lamp holder 6. The external power supply head 5 is mounted on the rear end wall of the frame body 2, and the external power supply head 5 is provided with an electrical connection terminal (not shown) electrically connected to the power supply 7. The socket 6 has a receiving cavity for accommodating the external power supply lamp cap 5 and the rear end portion of the frame body 2, and the lamp holder 6 correspondingly defines an opening 61 extending through the cover body air outlet 25. The lamp holder 6 can be electrically connected to an external power source. Of course, the LED light source module may not be provided with an external power supply lamp holder or a lamp holder, but adopts a structure as shown in FIG. 9 to directly connect the connection terminal 62 from the LED light source module to the external power supply. Referring to Figures 1 to 4, the enclosed outdoor lighting fixture is assembled by arranging the LED light source component 3, the fan 4, and the external power supply lamp head 5 on the frame 2 composed of the cover body 21 and the base 22 (see 3 and 4), the frame 2 is placed in the mounting hole 121 of the reflector 12 (see FIGS. 1 and 2), and the air outlet 25 at the rear end of the rear frame 2 is mounted. The outer chamber 14 and the LED light source element 3 are partially located in the inner chamber 15 between the reflector 12 and the light-transmitting cover 13. Then, the lamp holder 6 is sleeved on the rear end of the frame body 2, and the lamp holder 6, the frame body 2, and the reflector 12 are fixed together by the fastener, and then the lamp housing 11 is inserted from the lamp housing opening portion 110, and finally The light-transmitting lamp cover 13 is sealed in the lamp housing opening portion 110 and constitutes a sealing structure. Next, the air in the sealed hollow casing is taken out and filled with a pressure inert gas or dry air. After the assembly is completed, the lamp can be operated normally by connecting the two power terminals of the external power supply lamp head 5 and the lamp holder 6 to the municipal power supply. When the luminaire is working, the LED illuminating component 32 directly emits light through the translucent lampshade a, and the unique design of the structure and optical processing of the LED light source module helps to improve the illuminance, illumination uniformity and illumination angle of the luminaire. Can fully meet outdoor lighting. Referring to Figure 1 'closed outdoor lighting fixture φ heat dissipation principle in the above embodiment is as follows: when the fan 4 forcibly extracts air in the heat dissipation passage 20 at the air outlet 25 of the frame body 2, the air in the outer chamber 14 at this time The air hole 122 of the reflector 12 enters the inner chamber 15 and fills the entire inner chamber 15, cools the metal heat sink substrate 31 mounted on the frame body 2, and the air of the inner chamber 15 penetrates the metal heat sink substrate 31. The through hole 311 enters the heat dissipation channel 2 in the frame body 2 through the vent 23 to completely cool the heat on the front side, the side surface and the back side of the metal heat dissipation substrate 31, and the hot air in the heat dissipation channel 20 is forcibly extracted by the fan 4 The air outlet 25 is discharged and blown toward the inner wall of the lamp housing 11 to achieve a sufficient heat exchange by the inner wall of the lamp housing 11 to the outside air with a relatively low temperature. In this way, the heat generated by the LED light-emitting element 313 can be quickly and completely dissipated through the metal heat-dissipating substrate 31, thereby achieving the excellent effect of all-dimensional heat dissipation. Fig. 10 is a structural schematic view of another embodiment of a closed outdoor lighting fixture of a led light source module using a built-in power supply provided by the present invention. Based on the frame body 2 of the above embodiment and the reflector 12, in another embodiment, the cover body 21 is further provided with an opening 213, and the opening 213 is disposed at a position approximately in the middle of the top surface of the cover body 21. The reflector 12 further includes a fan chamber 123, 12 201120369. The fan 4 is placed in the fan chamber 123 and is connected to the opening 213 to form an air flow passage connecting the inner chamber 15 and the outer chamber 14. In order to comply with another embodiment, specifically, one end of the cover body 21 facing the air hole 122 is provided with an opening port 214, and the opening port 214 is connected to the air hole 122, so that the empty space of the outer chamber 14 can pass through the opening port 214 and The air hole 122 is connected to the inner chamber 15. Referring to FIG. 10, the heat dissipation principle of the closed outdoor lighting fixture in another embodiment is as follows: when the fan 4 forcibly extracts air in the heat dissipation passage 20 through the opening 213 in the fan chamber 123, at this time in the outer chamber 14 On the one hand, the air enters the inner chamber 15 through the air holes 122 and the opening 214 of the reflector 12, and on the other hand, enters the inner chamber 15 through the air outlet 25, so that the air fills the entire inner chamber 15 bidirectionally, and is cooled and installed. The metal heat dissipating substrate 31 on the frame body 2, while the air of the inner chamber 15 penetrates the through hole 311 in the metal heat dissipating substrate 31, enters the heat dissipating channel 20 in the frame body 2 through the vent 23, and completely cools the metal heat dissipating substrate 31. The heat on the front side, the side surface, and the back side, the hot air in the heat dissipation passage 20 is forcibly extracted by the fan 4, returned to the opening 213 through the fan chamber 123 to the outer chamber 14, and blown toward the inner wall of the lamp housing 11, so that The temperature is lowered by sufficient heat exchange between the inner wall of the lamp housing 11 and the outside air at a lower temperature. Such a double loop flow can accelerate the rapid and complete dissipation of the heat generated by the LED light-emitting element 313, and achieve the excellent effect of all-dimensional heat dissipation.
