Description

Technical Field

[0001] This utility model relates to a lamp structure, and in particular to a high heat dissipation lamp that is easy to maintain. Background Technology

[0002] A luminaire is a device or apparatus used to produce light, typically for illumination. The design and function of luminaires have continuously improved with technological advancements, resulting in an increasing variety of types and functions.

[0003] For some high-power lamps, there are usually two parts: a power supply box and a lamp body. Both the power supply box and the lamp body generate a lot of heat during operation. In order to ensure that the power supply box and the lamp body can work properly, some manufacturers in traditional lamps adopt a design that sets heat dissipation structures on both the power supply box and the lamp body. However, this increases the complexity of the power supply box and the lamp body structure, thereby increasing the cost of the product and increasing the economic burden on users.

[0004] In addition, during the maintenance of the power box of the lamp, one of the casings on the power box will be opened. If the lamp is being repaired at a height, there is a risk that the upper casing may fall if the operation is not done properly after the casing is opened. Utility Model Content

The lamp body 20 and the power box 30 share the heat sink 10, and the heat sink 10 dissipates heat from both the lamp body 20 and the power box 30.

[0028] The radiator 10 includes a main plate 11, two auxiliary plates 12 connected to the front and rear sides of the main plate 11 respectively, and a functional strip 13 connected to the top surface of the main plate 11 near the center. The extension direction of the auxiliary plates 12 is consistent with the extension direction of the main plate 11, and the extension direction of the functional strip 13 is consistent with the extension direction of the main plate 11. The two auxiliary plates 12 are symmetrically arranged and are curved downward and outward. The upper surfaces of the entire main plate 11 and the auxiliary plates 12 are exposed to the air to increase the heat dissipation area. By setting the functional strip 13, the overall bending rigidity of the radiator 10 can be increased. The main plate 11 and the two auxiliary plates 12 enclose an inner space 14 to accommodate the lamp body 20. While the radiator 10 dissipates heat from the lamp body 20, it can also enhance the waterproof and dustproof effect of the lamp body 20.

[0029] The lamp body 20 includes a lamp plate 22, a light-transmitting plate 21, a first sealing strip 23, a plurality of first fixing members 24 and a plurality of second fixing members 25. The upper end face of the light-transmitting plate 21 is concave in the middle and has an upward-facing elongated inner cavity 211. The inner wall of the inner cavity 211 has an arc-shaped transition in the cross section perpendicular to the main axis of the light-transmitting plate 21. The upper end face of the light-transmitting plate 21 has a sealing part 212. The sealing part 212 surrounds the outside of the opening of the inner cavity 211. The lamp has a sealing groove 213 on the sealing part 212. The sealing groove 213 is distributed around the entire sealing part 212. The first sealing strip 23 is installed on the sealing groove 213 and extends out from the sealing groove 213.

[0030] During assembly, the lamp panel 22 is mounted on the bottom surface of the panel body 11 by the first fixing member 24, and the light-transmitting panel 21 is mounted on the bottom surface of the panel body 11 by the second fixing member 25. During installation, the second fixing member 25 passes through the connecting edge portion of the light-transmitting panel 21 and is mounted on the panel body 11. The first sealing strip 23 is clamped between the light-transmitting panel 21 and the panel body 11, and the first sealing strip 23 surrounds the periphery of the lamp panel 22.

[0031] The power supply box 30 includes a box body 31, a cover plate 32, a positioning member 33 connecting the box body 31 and the cover plate 32, a plurality of first locking members 34 fixing the cover plate 32 to the box body 31, and a plurality of second locking members fixing the box body 31 to the heat sink 10. The box body 31 includes a main body portion 311, a connecting edge 312 connected to one side of the main body portion 311, a plurality of heat-conducting pillars 314 and fixing pillars 313 connected to the bottom of the main body portion 311, and a receiving groove provided on the main body portion 311. 317, the opening of the receiving groove 317 faces outward in a horizontal direction, the connecting edge 312 surrounds the outside of the opening of the receiving groove 317, and the box body 31 is also provided with a plurality of first latches 315. One end of the first latch 315 is connected to the bottom of the main body 311, and the end of the first latch 315 away from the main body 311 extends into the lower front side of the opening of the receiving groove 317. The end of the first latch 315 away from the main body 311 is provided with a positioning hole 316, and the wall of the positioning hole 316 is provided with internal threads. The heat-conducting column 314 and the fixing column 313 are both vertically connected to the bottom surface of the main body 311, and the bottom surfaces of the heat-conducting column 314 and the fixing column 313 are flush.

[0032] The cover plate 32 includes a cover plate body 323 and a plurality of second buckles 321 connected to the cover plate body 323.

When the cover plate 32 can be flipped upward and covered on the connecting edge 312 of the box body 31, the first locking member 34 further passes through the cover plate 32 and is installed on the connecting edge 312, thereby limiting the cover plate 32 and keeping the cover plate 32 in a state of being covered on the box body 31.

[0034] When the power supply box 30 is fixed to the heat sink 10, the bottom surfaces of the heat conduction column 314 and the fixing column 313 are in contact with the upper end surface of the plate body 11 of the heat sink 10. The second locking member passes through the fixing column 313 from the inside of the receiving groove 317 and is installed on the plate body 11 of the heat sink 10. The heat conduction column 314 can conduct the heat generated by the power supply box 30 when it is working to the heat sink 10.

[0035] The advantages of this utility model's easy-to-maintain, high-heat-dissipation lamp are as follows: By setting a main body 11 and two auxiliary plates 12 connected to the front and rear sides of the main body 11 on the heat sink 10, and setting heat-conducting columns 314 and fixing columns 313 on the power box 30, the bottom surfaces of the heat-conducting columns 314 and fixing columns 313 are in contact with the upper end surface of the main body 11. The main body 311 of the box body 31 is separated from the upper end surface of the main body 11 by a certain distance. The lamp plate 22 of the lamp body 20 is installed on the bottom surface of the main body 11. The heat sink 10 simultaneously dissipates heat from the lamp body 20 and the power box 30, effectively simplifying the heat dissipation structure of the lamp and reducing product costs. In addition, the box body 31 and the cover plate 32 of the power box 30 are connected into a whole by positioning parts 33, which effectively prevents the cover plate 32 from falling off during maintenance, reducing risks.

[0036] 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.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
