Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a floodlight. Background Technology

[0002] LEDs have advantages such as small size, energy saving, and environmental friendliness, and are widely used, especially in floodlights, where they illuminate and beautify landscapes at night. Common floodlights typically consist of a housing, heat dissipation module, light source module, lens module, and support module. Conventional heat dissipation modules are usually made of finned profiles molded in one piece, and the dimensions of these profiles are generally determined by the mold size. This method is only suitable for mass production of floodlights of the same specification and cannot be adjusted for floodlights of different sizes. Furthermore, the assembly of the lens module and housing generally requires screws for installation and fixation, resulting in slow assembly efficiency.

[0003] Therefore, there is a need for a floodlight that is simple in structure, easy to assemble, and can be used with heat dissipation modules of different sizes. Utility Model Content

The housing includes a recessed base. The heat dissipation module and the LED light panel are disposed within the recessed base. The top of the heat dissipation module abuts against the inner wall of the recessed base. The light-transmitting module abuts against the LED light panel and closes the recessed base.

[0006] The heat dissipation module includes multiple heat dissipation units assembled together. The number of heat dissipation units can be increased or decreased. Each heat dissipation unit includes a heat dissipation substrate. The upper and lower ends of the heat dissipation substrate are provided with a first connecting piece and a second connecting piece perpendicular to the heat dissipation substrate. The first connecting piece and the second connecting piece have the same orientation and the same length. The connection between the first connecting piece and the heat dissipation substrate is provided with multiple first slots. The end of the first connecting piece is provided with multiple first clips. The number of first clips is not greater than the number of first slots. The connection between the second connecting piece and the heat dissipation substrate is provided with a second slot. The end of the second connecting piece is provided with a second clip. The number of second clips is not greater than the number of second slots. When two adjacent heat dissipation units are assembled, the first clip of the later heat dissipation unit is inserted into the first slot of the earlier heat dissipation unit, and the second clip of the later heat dissipation unit is inserted into the second slot of the earlier heat dissipation unit.

[0007] In one embodiment, the heat sink substrate has multiple heat dissipation through holes.

[0008] In one embodiment, the heat dissipation hole is an elongated hole, with its longest end close to the first connecting piece and the second connecting piece.

[0009] In one embodiment, the first limiting members on both sides of the first connecting piece extend in a direction perpendicular to the heat dissipation substrate. When two adjacent heat dissipation units are assembled, the first limiting member of the latter heat dissipation unit abuts against the heat dissipation substrate of the former heat dissipation unit.

[0010] In one embodiment, the end of the second connecting piece is provided with a plurality of second limiting members, the extension direction of the second limiting members being parallel to the heat dissipation substrate, and when two adjacent heat dissipation units are assembled, the second limiting member of the latter heat dissipation unit abuts against the heat dissipation substrate of the former heat dissipation unit.

[0011] In one embodiment, the edge of the grooved substrate extends outward to have a first mounting frame and a plurality of insertion holes provided on the first mounting frame; the light-transmitting module includes a lens substrate and a second mounting frame provided on the edge of the lens substrate, the second mounting frame being provided with a plurality of plug-in buckles and a plurality of limiting members; the plug-in buckles are inserted into the insertion holes, and the limiting members abut against the first mounting frame.

[0012] In one embodiment, a plurality of the plug-in buckles and a plurality of the limiting members are arranged intersectingly on the second mounting frame.

[0013] In one embodiment, the lens substrate has a sealing groove inside the second mounting frame, and a sealing element is provided between the sealing groove and the LED light board.

[0014] In one embodiment, the grooved base has two mounting members on its outer side, and the two ends of the bracket are mounted on the mounting members, and the bracket is rotatable relative to the mounting members.

[0015] The advantages of this invention are as follows: the heat dissipation module can be quickly assembled using multiple heat dissipation units, and different numbers of heat dissipation units can be selected according to the size of the housing to meet the needs of floodlights of different sizes and power; the plug-in buckle inserts into the socket and abuts against the upper end of the first mounting frame, while the limiting member abuts against the lower end of the first mounting frame to achieve positioning.

The upper and lower ends of the heat dissipation substrate 211 are provided with a first connecting piece 212 and a second connecting piece 213 perpendicular to the heat dissipation substrate 211. The first connecting piece 212 and the second connecting piece 213 have the same orientation and length. The connection point between the first connecting piece 212 and the heat dissipation substrate 211 is provided with multiple first slots 214. The end of the first connecting piece 212 is provided with multiple first clips 215, the number of first clips 215 not exceeding the number of first slots 214.

The end of the second connecting piece 213 is provided with a second clip 217, the number of second clips 217 not exceeding the number of second slots 216. When two adjacent heat dissipation units 21 are assembled, the first clip 215 of the later heat dissipation unit 21 is inserted into the first slot 214 of the previous heat dissipation unit 21, and the second clip 217 of the later heat dissipation unit 21 is inserted into the second slot 216 of the previous heat dissipation unit 21.

[0034] Preferably, to improve the heat dissipation effect of the heat dissipation unit 21, the heat dissipation substrate 211 is provided with a plurality of heat dissipation through holes 210. Adjacent heat dissipation units 21 can achieve lateral ventilation and heat dissipation not only through the gap between them, but also through the heat dissipation through holes 210 between them.

[0038] The heat dissipation module 2 of this utility model can be quickly assembled through multiple heat dissipation units 21, and different numbers of heat dissipation units 21 can be selected according to the size of the outer shell 1 to meet the needs of floodlights 100 of different specifications; the plug buckle 43 is inserted into the plug hole 13 and abuts against the upper end of the first mounting frame 12, and the limiting member 44 abuts against the lower end of the first mounting frame 12 to achieve limitation. The combination of the plug buckle 43 and the limiting member 44 fixes the module, replacing the traditional screw fixing installation, which makes the assembly quick and efficient.

[0039] For more details, please refer to Figure 6 and Figure 7 The lens substrate 41 has a sealing groove 45 inside the second mounting frame 42, and a sealing element (not shown) is provided between the sealing groove 45 and the LED light board 3.

[0040] For more details, please refer to Figure 1 , Figure 3 and Figure 6 The recessed base 11 has two mounting members 14 on its outer side. The two ends of the bracket 5 are mounted on the mounting members 14, and the bracket 5 is rotatable relative to the mounting members 14. The recessed base 11 has multiple heat dissipation ventilation holes 111, which can promptly remove the heat from the heat dissipation module 2 outside the floodlight 100. Preferably, the heat dissipation ventilation holes 111 are distributed on five surfaces of the recessed base 11: front, back, left, right, and top.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
