[0028] The present application is described below through specific embodiments.

[0029] Embodiment 1:

[0030] like Figures 1 to 5 As shown, in one embodiment of the present application, a lamp is provided, comprising: a bracket 1, a lamp body assembly 2 and a power supply assembly 3. The bracket 1 has a mounting cavity 101, and a lamp body mounting portion 13 is located at one side of the mounting cavity 101. The lamp body assembly 2 comprises a lamp body 21 for lighting, the lamp body assembly 2 is mounted on the lamp body mounting portion 13, and is located at one end of the bracket 1, and the lamp body assembly 2 is used to emit light for lighting. The power supply assembly 3 comprises a power supply 32, the power supply assembly 3 is mounted in the mounting cavity 101, the power supply assembly 3 is electrically connected to the lamp body assembly 2 to supply power to the lamp body assembly 2, and there is a gap between the power supply assembly 3 and the lamp body assembly 2, the power supply 32 can be a battery, or a power supply circuit, or other components that can realize the function of supplying power to the lamp body assembly 2.

[0031] Since the lamp body component 2 and the power supply component 3 are installed completely separately, the power supply component 3 can exchange heat with the air to the maximum extent, reduce the temperature of the power supply component 3, and increase the life of the lamp. There is no need to increase the lamp body component 2 and reduce the power to meet the lighting needs and control the temperature. The lamp utilization rate is high and the cost is saved. In this embodiment, the power of the lamp is 400-500W.

[0032] The mounting cavity 101 on the bracket 1 is a semi-open structure. The bracket 1 has a bottom wall 11 and a side wall 12. The side wall 12 is vertically mounted on the bottom wall 11. At least one bottom wall 11 and at least one side wall 12 enclose a semi-open mounting cavity 101. The mounting cavity 101 has at least one opening for placing the power supply component 3 into or taking it out of the mounting cavity 101. A power supply component mounting portion can be provided in the mounting cavity 101 for installing the power supply component 3, or the power supply component 3 can be directly installed on the side wall 12 or the bottom wall 11. The lamp body mounting portion 13 is provided on the outside of the mounting cavity 101. After the lamp body component 2 is installed on the lamp body mounting portion 13, it does not interfere with the installation of the power supply component 3. The accommodating space of the mounting cavity 101 enclosed by the bottom wall 11 and the side wall 12 is larger than the outer contour volume of the power supply component 3, so that there can be a gap between the lamp body mounting portion 13 and the power supply component 3, so that the lamp body component 2 and the power supply component 3 can be installed separately, thereby ensuring the heat exchange efficiency of the power supply component 3.

[0033] In one embodiment, the bracket 1 has two bottom walls 11 and three side walls 12, the two bottom walls 11 are arranged opposite to each other, and the three side walls 12 are arranged between the two bottom walls 11. The two bottom walls 11 and the three side walls 12 enclose an installation cavity 101 with an opening, and the power supply component 3 can be placed in or taken out of the installation cavity 101 through the opening. One of the two bottom walls 11 is used to set the hanging structure, and the lamp body mounting part 13 can be set on the outside of the other bottom wall 11, and can also be set on the outside of a side wall 12, both of which can realize the separate installation of the lamp body component 2 and the power supply component 3.

[0034] In one embodiment, the bracket 1 has two opposite side walls 12, and a mounting cavity 101 is formed between the two side walls 12. The openings on both sides of the two opposite side walls 12 can be used to put in or take out the power supply assembly 3. The bracket 1 has a low directional requirement when installed, which reduces the difficulty of installation, and the relatively arranged openings can increase the air circulation in the mounting cavity 101, so that the heat exchange efficiency between the power supply assembly 3 and the air is higher.

[0035] In one embodiment, the bracket 1 is a U-shaped bracket, and the bracket 1 includes a bottom wall 11, two side walls 12 are relatively arranged on both sides of the bottom wall 11, and the opposite side of the bottom wall 11 is a lamp body mounting portion 13. A bottom wall 11 and two side walls 12 are enclosed to form a U-shaped bracket, and a mounting cavity 101 is formed between the two side walls 12. The power supply component 3 is installed in the mounting cavity 101, and the lamp body mounting portion 13 is arranged on the opposite side of the bottom wall 11 for mounting the lamp assembly 2, which can make the lamp as a whole present a symmetrical structure, and the overall force balance performance is better, avoiding damage to the structural parts, and increasing the life of the lamp.

[0036] When the lamp is working, the power supply assembly 3 is fixedly installed in the installation cavity 101. When the power supply assembly 3 is abnormal or needs to be repaired, the power supply assembly 3 needs to be taken out of the installation cavity 101, so the power supply assembly 3 and the bracket 1 are detachably connected.

[0037] In one embodiment, a male buckle or a female buckle is provided in the installation cavity 101 and on the power supply assembly 3, and the installation cavity 101 is snap-connected with the power supply assembly 3. When the power supply assembly 3 needs to be taken out, the power supply assembly 3 is pried to disengage the male buckle and the female buckle. When the power supply assembly 3 needs to be inserted, the power supply assembly 3 is pressed to snap-connect the male buckle and the female buckle, thereby realizing a detachable connection between the power supply assembly 3 and the bracket 1.

[0038] In one embodiment, the power supply assembly 3 and the bracket 1 are connected by threads, which can also achieve a detachable connection between the power supply assembly 3 and the bracket 1.

[0039] The lamp in this embodiment is usually installed at a higher position from the ground and generally works outdoors in a relatively harsh working environment. Therefore, the connection method between the power supply assembly 3 and the bracket 1 in this embodiment is a threaded connection with higher reliability in harsh environments. In some embodiments, when the working environment of the lamp is relatively good, a detachable connection method such as a snap connection can also be selected to connect the power supply assembly 3 and the bracket 1.

[0040] In one embodiment, the bracket 1 has a guide rail, and the power supply assembly 3 is slidably connected to the guide rail so that the power supply assembly 3 can slide into or out of the installation cavity 101. According to the guide rail structure, when the power supply assembly 3 needs to be removed, the power supply assembly 3 is loosened from the bracket 1, and then the power supply assembly 3 is pulled out of the installation cavity 101 along the guide rail, and the power supply assembly 3 can be removed; when the power supply assembly 3 needs to be installed, the power supply assembly 3 is pushed into the installation cavity 101 to the installation position along the guide rail, and then the power supply assembly 3 is fixed on the bracket 1, and the installation of the power supply assembly 3 is completed; when the power supply assembly 3 is disassembled or installed, it can be pulled out or pushed into the installation cavity 101 like a drawer, which is easy to operate and reduces labor costs.

[0041] In one embodiment, the bracket 1 is provided with a guide groove, and the power supply assembly 3 is provided with a guide protrusion. The guide protrusion is inserted into the guide groove, so that the power supply assembly 3 can be taken in a drawer-like manner. In some embodiments, the guide groove is provided on the power supply assembly 3, and the guide protrusion is provided on the bracket 1, so that the power supply assembly 3 can be taken in a drawer-like manner, and the guide protrusion can extend out of the bracket 1, so as to facilitate the alignment of the guide groove and the guide protrusion.

[0042] In one embodiment, a guide plate 121 is provided on the side wall 12, and the power supply assembly 3 is slidably connected to the guide plate 121. In this embodiment, the guide plate 121 is made by folding a section of the side wall 12 inward, and the processing is simple. The guide plate 121 is set near the lamp mounting portion 13. When the guide plate 121 is set here, the guide plate 121 can support the power supply assembly 3, and no additional operation is required to align the guide plate 121 when the power supply assembly 3 is installed. When the power supply assembly 3 is placed on the guide plate 121, the power supply assembly 3 and the guide plate 121 can be aligned due to gravity. The power supply assembly 3 can be pushed and pulled, and the power supply assembly 3 can slide on the guide plate 121, and the drawer-style placement of the power supply assembly 3 can also be achieved. In order to make it more convenient to take and put the power assembly 3, in one embodiment, a limiting plate 122 is further provided on the side wall 12, and the limiting plate 122 is provided on one side of the guide plate 121. When the power assembly 3 needs to be taken out, the power assembly 3 is first loosened from the bracket 1, and then the power assembly 3 is pulled out from the installation cavity 101 along the guide plate 121, and the power assembly 3 can be taken out; when the power assembly 3 needs to be installed, the power assembly 3 is pushed into the installation cavity 101 along the guide plate 121, and the installation positioning is completed when the power assembly 3 hits the limiting plate 122, and then the power assembly 3 is fixed on the bracket 1, and the installation of the power assembly 3 is completed. Through the cooperation of the guide plate 121 and the limiting plate 122, when the power assembly 3 is disassembled or installed, it can be pulled out or pushed into the installation cavity 101 like a drawer, which is convenient for operation. Considering that the lamp in this embodiment is often installed at a high position from the ground, the labor cost of replacing the power assembly 3 can be greatly reduced. In this embodiment, two guide plates 121 are relatively arranged near the lamp mounting portion 13, the guide plates 121 are arranged parallel to the bottom wall 11, and the limit plate 122 is arranged at a suitable position on the inner side of the side wall 12 according to the size of the bracket 1 and the power supply assembly 3, so as to realize the installation positioning of the power supply assembly 3.
