[0027] Example 1

[0028] Combination Figures 1 to 4 As shown, the lamp body structure of the utility model is schematically shown, including a housing 10. The housing 10 is provided with a first mounting portion 20 and a second mounting portion 30, and the first mounting portion 20 and the second mounting portion 30 are respectively located on two opposite sides of the housing 10. The first mounting portion 20 is used to install the power supply device, and the second mounting portion 30 is used to install the light-emitting component 40, wherein the first mounting portion 20 is used to install the power supply device and can also transfer the heat of the power supply device to the housing 10, and similarly, the second mounting portion 30 is used to install the light-emitting component 40 and can also transfer the heat generated by the light-emitting component 40 when emitting light to the housing 10. The projections of part of the first mounting portion 20 and part of the second mounting portion 30 on the housing 10 overlap, and the first mounting portion 20, the second mounting portion 30 and the housing 10 are an integrally formed structure, so the heat generated by the light-emitting component 40 can be transferred from the first mounting portion 20 to the second mounting portion 30 via the housing 10, so that the heat of the first mounting portion 20, the second mounting portion 30 and the housing 10 is more evenly distributed, thereby improving the heat dissipation efficiency.

[0029] The first mounting portion 20, the second mounting portion 30 and the housing 10 can be formed by metal integral die casting or plastic integral injection molding, which is conducive to heat transfer between the first mounting portion 20, the second mounting portion 30 and the housing 10. Of course, in order to improve the heat conduction efficiency, the first mounting portion 20, the second mounting portion 30 and the housing 10 are preferably made of metal material, such as the existing aluminum alloy.

[0030] Specifically, combined Figure 2 and Figure 3 The shell 10 has a front and a back, the first mounting portion 20 is located on the back of the shell 10, and the second mounting portion 30 is located on the front of the shell 10. The projections of the end of the first mounting portion 20 and the end of the second mounting portion 30 on the shell 10 overlap each other, which is also conducive to the first mounting portion 20 directly transferring heat to the second mounting portion 30. When the shell 10 is set on the lamp post, the front of the shell 10 faces the ground, so that the light-emitting component 40 in the second mounting portion 30 can emit light and irradiate the ground. The light-emitting component 40 facing the ground can not only illuminate the ground in a larger range, but also facilitate the installation and maintenance personnel to perform daily maintenance and replacement of the light-emitting component 40. The first mounting portion 20 is set away from the ground. The maintenance cycle of the power supply device installed in the first mounting portion 20 is longer than that of the light-emitting component 40, so it is more appropriate to set it in the first mounting portion 20 away from the ground.

[0031] like Figure 3 The back of the housing 10 is provided with a heat dissipation groove 12 connected to the second mounting portion 30, that is, the heat dissipation groove 12 and the second mounting portion 30 are arranged opposite to each other. Further, the back of the housing 10 is provided with a plurality of mutually parallel heat dissipation fins 11, and the heat dissipation groove 12 is provided between two adjacent heat dissipation fins 11. The heat dissipation fins 11 (and the heat dissipation groove 12) can increase the heat dissipation area, which is conducive to efficient heat dissipation of the second mounting portion 30. Based on the above structure, the back of the housing 10 is divided into two adjacent areas by the first mounting portion 20 and the heat dissipation groove 12, which makes the arrangement of various structures / components on the housing 10 more compact and maximizes the use of the limited space on the housing 10.

[0032] Furthermore, the first mounting portion 20 is provided with a first cavity 21 for accommodating the power supply device, and a plurality of first mounting holes 211 are provided in the first cavity 21. The power supply device can be connected to the first mounting holes 211 by existing fasteners such as screws and bolts; the second mounting portion 30 is provided with a second cavity 31 for accommodating the light-emitting component 40, and a plurality of second mounting holes 311 are provided in the second cavity 31. The light-emitting component 40 can be connected to the second mounting holes 311 by existing fasteners such as screws and bolts. Figure 3 As shown, the end of the second mounting portion 30 forms a raised overlapping area 32 in the first cavity 21 .

[0033] like Figure 2 The housing 10 is provided with a first wire hole 13, which is opened on the heat conducting block 32. The first cavity 21 is connected to the second cavity 31 through the first wire hole 13, that is, one end of the first wire hole 13 is connected to the inner wall of the first cavity 21, and the other end of the first wire hole 13 is connected to the inner wall surface of the second cavity 31. In this embodiment, a part of the second cavity 31 extends to the back of the first cavity 21, so a part of the second cavity 31 is arranged opposite to the first cavity 21, which can be combined with Figure 3 As shown, the extension structure of the part of the second cavity 31 extending to the back of the first cavity 21 in the first cavity 21 is the overlap area 32, and the first wire hole 13 is located at the overlap of the first mounting portion and the second mounting portion on the shell (i.e., the overlap area 32). Such a structure facilitates the processing of the first wire hole 13. On the part of the second cavity 31 extending to the back of the first cavity 21, the first wire hole 13 and the wire groove 34 are provided on the bottom wall of the part of the second cavity 31, one end of the wire groove 34 is connected to one side of the first wire hole 13, and the other end of the wire groove 34 extends to the part of the second cavity 31 that is not arranged opposite to the first cavity 21. Therefore, power lines, control lines and other wiring harnesses can pass through the first wire hole 13 to connect the power supply device and the light-emitting component 40.

[0034] like Figure 3 A plurality of reinforcing ribs 212 are provided on the inner wall surface of the first concave cavity 21. Specifically, the first concave cavity 21 has an inner side wall and an inner bottom surface, and a plurality of inner side walls are provided around the inner bottom surface. The reinforcing ribs 212 are respectively connected to the inner side wall and the inner bottom surface of the first concave cavity 21, thereby improving the structural strength of the first mounting portion.

[0035] like Figure 4 , a plurality of heat dissipation ribs 33 are provided in the second cavity 31. When the number of heat dissipation ribs 33 is multiple, a portion of the heat dissipation ribs 33 and another portion of the heat dissipation ribs 33 are perpendicular to each other, so as to divide the second cavity 31 into a plurality of sub-chambers 312. The light emitting assembly 40 located in the second cavity 31 is connected to the end of the heat dissipation rib 33. Some / all of the second mounting holes 311 in the second cavity 31 are provided on the heat dissipation rib 33. The heat dissipation rib 33 is not only used to transfer the heat of the light emitting assembly 40 to the second mounting portion 30, but also used to install and fix the light emitting assembly 40. In order to arrange the wiring harness in the second cavity 31, some / all of the heat dissipation ribs 33 are provided with a wire groove 331, and the wiring harness can pass through the heat dissipation rib 33 through the wire groove 331. The light emitting assembly 40 includes a control circuit board and a plurality of lamp beads arranged on the control circuit board. The control circuit board is installed in the second mounting hole 311 through a fastener. The control circuit board is perpendicular to the heat dissipation rib 33, and the control circuit board is attached to the heat dissipation rib 33.

[0036] In this embodiment, there are multiple second concave cavities 31, and each second concave cavity 31 can be provided with a light emitting assembly 40. The housing 10 is provided with a second wire hole 14, and two adjacent second concave cavities 31 are connected through the second wire hole 14, so that the wire harness can pass through the multiple second concave cavities 31.

[0039] To summarize, the shell 10 is provided with a first mounting portion 20 and a second mounting portion 30, the first mounting portion 20 is used to install a power supply device, and the second mounting portion 30 is used to install a light-emitting component 40, and the projections of part of the first mounting portion 20 and part of the second mounting portion 30 on the shell 10 overlap, and the first mounting portion 20, the second mounting portion 30 and the shell 10 are an integrally formed structure, and the heat generated by the light-emitting component 40 can be transferred from the first mounting portion 20 to the second mounting portion 30 via the shell 10, so that the heat of the first mounting portion 20, the second mounting portion 30 and the shell 10 is more evenly distributed, thereby improving the heat dissipation efficiency.
