[0021] like Figure 1 、 Figure 2 and Figure 3 As shown, the present invention discloses a multi-module spliced ​​lamp 10 that can adjust the heat dissipation wind direction, including: a plurality of lighting modules 100, a spliced ​​main rod 200, and two sets of wind direction adjustment components 300.

[0022] like Figure 1 、 Figure 2 and Figure 3 As shown, several lighting modules 100 are arranged in a straight line, adjacent to each other, and spliced ​​onto a spliced ​​main pole 200. Two sets of wind direction adjustment assemblies 300 are respectively provided at either end of the spliced ​​main pole 200, with the several lighting modules 100 positioned between the two sets of wind direction adjustment assemblies 300. In this embodiment, there are three sets of lighting modules 100, each with a power of 300W. The length of the spliced ​​main pole 200 can be selected based on the number of lighting modules 100 to be spliced. The spliced ​​main pole 200 and the several lighting modules 100 are interlocked to achieve a stable assembly.

[0023] like Figure 4 As shown, the lighting module 100 includes: a light board 110, a light source 120 (such as Figure 1 ), heat dissipation fins 130 are provided on the back of the light board 110. In this embodiment, the light source 120 is an LED light board. The light source 120 is used to emit bright light outward, and the heat dissipation fins 130 are used to achieve heat dissipation.

[0024] like Figure 4 As shown, the back of the light board 110 is provided with a splicing structure 140, and the light board 110 is spliced ​​on the splicing main rod 200 through the splicing structure 140 on its back, and a through ventilation chamber 400 is formed between the splicing structures 140 and the splicing main rod 200 (as shown in FIG. Figure 5 The ventilation chamber 400 cooperates with the wind direction adjustment component 300 to dissipate heat for the lamp and adjust the wind direction to meet the needs of use.

[0025] like Figure 6As shown, the wind direction adjustment component 300 includes an end cover 310 and a heat dissipation fan 320 provided on the end cover 310. The heat dissipation fan 320 is located at the end of the ventilation chamber 400. A vertical ventilation hole 311 is opened on the end cover 310; a lateral ventilation hole 101 is formed between two adjacent lighting modules 100 (such as Figure 2 shown).

[0026] One set of cooling fans 320 blows air into the ventilation chamber 400, while the other set of cooling fans 320 exhausts air into the ventilation chamber 400. External air enters the ventilation chamber 400 through the vertical ventilation holes 311 of one set of end covers 310, and then exits through the vertical ventilation holes 311 of the other set of end covers 310. Alternatively, the two sets of cooling fans 320 blow air into the ventilation chamber 400 at the same time, and the outside air enters the ventilation chamber 400 through the vertical ventilation holes 311 of the two sets of end covers 310 and then comes out through the lateral ventilation holes 101.

[0027] In this embodiment, the number of the splicing structures 140 is two groups (eg Figure 4 As shown), the two sets of splicing structures 140 are respectively located on both sides of the heat dissipation fins 130; Figure 4 As shown, the heat dissipation fin 130 has a plurality of fin monomers 131 arranged in sequence, a heat dissipation gap 132 is formed between two adjacent fin monomers 131, and the heat dissipation gap 132 is connected to the ventilation chamber 400; the number of the splicing main rods 200 is two.

[0028] like Figure 3 and Figure 4 As shown, the splicing structure 140 further includes: a fixing plate 141 disposed near the heat dissipating fins 130, and a limiting plate 142 disposed away from the heat dissipating fins 130; the fixing plate 141 is provided with heat dissipating holes 143; and a ventilation slot chamber 144 is formed between the fixing plate 141 and the limiting plate 142 (a plurality of ventilation slot chambers 144 are spliced ​​together and cooperate with the splicing main rod 200, thereby forming a ventilation chamber 400). The fixing plate 141 is fastened to the splicing main rod 200 via a fastener 145; the limiting plate 142 is provided with a limiting groove 142a, and the splicing main rod 200 has a limiting rib 201 that cooperates with the limiting groove 142a. Preferably, the fastener 145 is a fastening bolt.

[0029] Next, the assembly process of the multi-module spliced ​​lamp 10 with adjustable heat dissipation direction of the above structure is described: Arrange several lighting modules 100 in a straight line and closely together on the splicing main rod 200. Specifically, each lighting module 100 slides into the limiting rib 201 of the splicing main rod 200 through the limiting groove 142a on its limiting plate 142. The limiting rib 201 is used to limit the limiting groove 142a to prevent the lighting module 100 from falling off the splicing main rod 200. After all lighting modules 100 are spliced ​​to the splicing main rod 200, the fixing plate 141 and the splicing main rod 200 are fastened together using fasteners 145. Thus, all lighting modules 100 and the splicing main rod 200 form a stable assembly structure, and a continuous ventilation chamber 400 is formed between the splicing structures 140 and the splicing main rod 200. Fix the two sets of wind direction adjustment components 300 to the two ends of the spliced ​​main rod 200 respectively, and align the cooling fan 320 thereon with the ventilation chamber 400. At this point, a complete lamp structure is assembled. like Figure 7 As shown, the assembled lamp can be hidden in the installation groove of the ceiling, the heat dissipation fins 130 on the back of the lamp board 110 are accommodated in the installation groove, and the light source 120 on the front of the lamp board 110 is located outside the installation groove to achieve the purpose of lighting.

[0030] The working principle and usage of the multi-module spliced ​​lamp 10 with adjustable heat dissipation direction are described below: Install the assembled lamp in a concealed manner in the installation groove of the ceiling; Powering the light source 120 so that the light source 120 emits light and illuminates the surrounding environment; When the light source 120 emits light, heat is generated. This heat is transferred to the heat dissipation fins 130 on the back of the light board 110. However, the heat dissipation fins 130 are hidden in the mounting slot and cannot effectively dissipate heat. In this case, the wind direction adjustment component 300 is required to dissipate heat from the heat dissipation fins 130. At the same time, the heat generated by the heat dissipation fins 130 is used to provide warm air of different wind directions to the environment. For example, one group of cooling fans 320 blows air into the ventilation chamber 400, while the other group of cooling fans 320 draws air into the ventilation chamber 400. As a result, outside air enters the ventilation chamber 400 through the vertical ventilation holes 311 of one group of end covers 310, and then exits through the vertical ventilation holes 311 of the other group of end covers 310. In the process of air passing through the ventilation chamber 400, the heat generated by the heat dissipating fins 130 enters the ventilation chamber 400 through the heat dissipating holes 143 on the fixing plate 141, thereby achieving heat dissipation. In this process, the hot air exiting the vertical ventilation holes 311 of the other group of end covers 310 will flow downward and directly blow onto the surface of an object, thereby meeting the user's specific wind direction requirements. It should be noted here that outside air will also be sucked into the ventilation chamber 400 through the side ventilation holes 101, but this does not affect the heat dissipation function and will not change the wind direction of the hot air exiting the vertical ventilation holes 311. For another example, the two sets of cooling fans 320 simultaneously blow air into the ventilation chamber 400. External air enters the ventilation chamber 400 through the vertical ventilation holes 311 of the two sets of end covers 310. Since the two sets of cooling fans 320 blow air in opposite directions, most of the air in the ventilation chamber 400 will be discharged through the side ventilation holes 101, thereby achieving heat dissipation. In this process, the hot air from the side ventilation holes 101 is discharged horizontally and does not blow directly downward toward objects, thereby meeting the user's specific wind direction requirements. It can be seen that in the process of adjusting the wind direction, it is only necessary to control the forward and reverse rotation of the two groups of cooling fans 320, and at the same time cooperate with the vertical ventilation holes 311 and the side ventilation holes 101 to achieve wind direction control without setting a one-way valve or controller at the vertical ventilation holes 311 or the side ventilation holes 101.

[0031] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
