Description

Technical Field

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

[0002] There is a kind of Figure 1 , Figure 2 The outdoor street LED street light housing shown is an elliptical shell structure, including a first top cover 1 and a first bottom cover 2. The top of the first top cover 1 is a flat structure with heat dissipation holes. The first bottom cover 2 is equipped with a first heat sink 3, which is an integral structure. The first heat sink 3 is matched with the bottom size of the first bottom cover 2. Several first lamp groups 4 are provided on the first heat sink 3. The first lamp groups 4 are used for outdoor lighting. The first top cover 1 and the first bottom cover 2 are fastened with threads after being fastened together. The following problems were found during long-term use: 1. Because the first heat sink 3 is a single piece, when the first lamp assembly 4 needs maintenance, the first top cover 1 must be removed from the first bottom shell 2, and then the first heat sink 3 must be disassembled and reassembled as a whole. This is inconvenient for maintenance. Moreover, there is no place to put the first top cover 1 for work at heights, requiring two people to work together or to find a temporary place. This results in long maintenance time and low efficiency. 2. Because the top of the first top cover 1 is a flat structure, dead branches and leaves fall onto it and also fall into the first bottom shell 2 through the heat dissipation holes. Over time, this accumulation will affect the lifespan of the lamp. During the rainy season, rainwater enters the lamp housing through the heat dissipation holes. The large amount of water cannot be drained in time, and the evaporation of water takes a long time, which can easily cause circuit abnormalities and affect the lifespan of the lamp.

Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and objectives that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0022] like Figures 3-5 As shown, a lamp housing includes a second top cover 5 and a second bottom cover 6. The second top cover 5 and the second bottom cover 6 are elliptical structures. Flip hinges 12 are provided at the ends of the second top cover 5 and the second bottom cover 6, allowing them to flip and snap together. The bottom wall of the second bottom cover 6 is planar, and a mounting plate 7 is provided on the bottom wall. Several second heat sinks 8 are located at the center of the mounting plate 7, and each second heat sink 8 is matched with a set of second lamp groups 10. When a particular second lamp group 10 needs maintenance, only the corresponding second heat sink 8 needs to be removed and installed. Third heat dissipation holes 701 are provided on both sides of the mounting plate 7 to dissipate heat generated inside the housing. The third heat dissipation holes 701 are located on both sides of the second heat sinks 8. An arc-shaped sidewall is formed between the sidewall and the bottom wall of the second bottom cover 6. Figure 5, Figure 6 As shown, several through-holes 601 are provided on the arc-shaped sidewall. The second heat dissipation holes 601 are used to dissipate the heat generated inside the shell. A water collection trough 602 is provided at the junction of the arc-shaped sidewall and the bottom wall. The second heat dissipation holes 601 and the water collection trough 602 are connected, and the connected part forms the drain outlet of the water collection trough 602. When rainwater enters the second bottom shell 6, the rainwater is collected in the water collection trough 602 along the arc-shaped sidewall, and the rainwater in the water collection trough 602 flows out through the drain outlet. The top outer wall of the second top cover 5 is entirely arc-shaped to facilitate the sliding off of fallen branches and leaves. Several through-holes 501 are provided on both sides of the second top cover 5. The first heat dissipation holes 501 are used to dissipate the heat generated inside the shell. Figure 5 As shown, a support frame assembly 9 is provided on the inner cavity top wall of the second top cover 5 to support the second top cover 5. During maintenance, the support frame assembly 9 supports and opens the second top cover 5 for easy maintenance.

[0023] like Figure 5 As shown, the support frame assembly 9 includes a rotating shaft 901, a support plate 902, and a fixing seat 903. The rotating shaft 901 is fixedly installed at the center line of the inner cavity top wall of the second top cover 5. The rotating shaft 901 is close to the flip hinge 12. The support plate 902 is fixedly installed on the rotating shaft 901 and can rotate around the rotating shaft 901. The other end of the support plate 902 is provided with a fixing seat 903, which is fixedly installed on the inner cavity top wall of the second top cover 5. The other end of the support plate 902 is provided with a locking rod 9021, and the fixing seat 903 is provided with a locking groove 9031, in which the locking rod 9021 is locked. When the second lamp assembly 10 needs maintenance, open the second top cover 5, remove the end lever 9021 of the support plate 902 from the slot 9031, open the second top cover 5 to the required opening and closing state, rotate the support plate 902, and the end of the support plate 902 abuts against the second bottom shell 6 to keep the second top cover 5 in the open state, so that maintenance personnel can easily perform maintenance on the second lamp assembly 10.

[0024] like Figure 3 As shown, the positions of the first heat dissipation hole 501 and the third heat dissipation hole 701 are corresponding vertically. On the one hand, the heat generated inside the lamp housing can be quickly discharged outside the housing through air circulation, achieving a good heat dissipation effect. On the other hand, the corresponding vertical arrangement of the first heat dissipation hole 501 and the third heat dissipation hole 701 can also quickly discharge rainwater that has entered the housing during the rainy season, accelerating water vapor evaporation.

[0025] like Figure 3As shown, the top of the outer side wall of the second top cover 5 is provided with a plurality of first connecting holes 502, and the top of the outer side wall of the second bottom shell 6 is provided with a plurality of second connecting screw holes 603. The first connecting holes 502 and the second connecting screw holes 603 are matched and matched accordingly. After the second top cover 5 and the second bottom shell 6 are assembled, the second top cover 5 and the second bottom shell 6 are fastened together, and the first connecting holes 502 and the second connecting screw holes 603 are tightened with screws to ensure that the second top cover 5 and the second bottom shell 6 are fastened securely.

[0026] like Figure 3 As shown, the second bottom shell 6 also contains an electrical control box 11 for circuit integration and connection.

[0027] In this embodiment, three sets of the second heat sink 8 and the second lamp group 10 are provided. The number of the second heat sink 8 and the second lamp group 10 can be set according to the actual application scenario.

[0028] In this embodiment, a lamp housing is provided, wherein the ends of the second bottom shell 6 and the second top cover 5 are connected by a hinge 12. A mounting plate 7 is installed inside the second bottom shell 6, and second heat sinks 8 are arranged on the mounting plate 7. A second lamp assembly 10 is correspondingly arranged on the second heat sinks 8. The wiring of the second lamp assembly 10 is integrated into the electrical control box 11, and the support frame assembly 9 is fixed inside the second top cover 5. After installation, the second top cover 5 and the second bottom shell 6 are fastened together, and the first connecting hole 502 and the second connecting screw hole 603 are tightened with screws. Finally, the lamp housing can be fixedly installed on the street light pole. When the second lamp assembly 10 needs maintenance, unscrew the screws of the second top cover 5 and the second bottom shell 6, open the second top cover 5, remove the end lever 9021 of the support plate 902 from the slot 9031, open the second top cover 5 to the required opening and closing state, rotate the support plate 902, and the end of the support plate 902 abuts against the second bottom shell 6 to keep the second top cover 5 in the open state, so that maintenance personnel can easily perform maintenance on the second lamp assembly 10.
