Description

Technical Field

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

[0002] Ceiling lights are a type of lighting fixture. As the name suggests, they are called ceiling lights because the top of the fixture is relatively flat and the bottom is completely flush with the ceiling during installation. Light sources include ordinary incandescent bulbs, fluorescent lamps, high-intensity discharge lamps, halogen lamps, and LEDs. LED ceiling lights are the most popular on the market and are frequently chosen for homes, offices, entertainment venues, and various other places. Ceiling lights are generally installed and fixed to the interior wall and ceiling using multiple screws. This installation method is relatively time-consuming and labor-intensive, requiring tools for each installation and removal, making subsequent maintenance inconvenient. For example, utility model patent application number 2021221961998 discloses a ceiling light lampshade fixing structure and a ceiling light. By compressing two spring clips, the connecting plate drives the locking post to retract. When the locking post is aligned with the corresponding annular groove, the compression force of the spring clips is released, the spring clips return to their original position, and the locking post is fitted into the annular groove. However, this installation method is convenient for installation, but when disassembling, the spring clips need to be compressed again. Generally, auxiliary tools or pre-designed structures are used, making disassembly difficult and requiring operating space. Another installation method uses bolts, which requires tightening multiple screws and is cumbersome to operate. Utility Model Content

[0034] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] Reference Figures 1 to 3 The ceiling light of this utility model embodiment includes a lamp housing structure and an LED chip, with the LED chip built into the lamp housing structure. Specifically, refer to... Figures 3 to 7 The lamp housing structure includes a bottom shell 100, a snap-fit ​​portion 200, and a top shell 300. The bottom shell 100 is rectangular. The snap-fit ​​portion 200 is located at the four corners of the bottom shell 100 and includes a connecting post 210 and a hook portion 220. The hook portion 220 is fixed to the end of the connecting post 210. The four corners of the top shell 300 are provided with snap-fit ​​holes 310, and the snap-fit ​​holes 310 have abutment portions 311 inside. The snap-fit ​​portion 200 can be inserted into the snap-fit ​​holes 310. The connecting post 210 is deformable so that the hook portion 220 and the abutment portion are snap-fitted and fixed, or so that the hook portion 220 and the abutment portion are separated. The bottom shell 100 is provided with a mounting position 130, and the top shell 300 is provided with a light-transmitting portion 330. The lamp bead is fixedly installed in the mounting position 130, and the lamp bead and the light-transmitting portion 330 are positioned correspondingly.

[0036] During installation of the ceiling light according to this embodiment, after fixing the base shell 100 to the ceiling, align the snap-fit ​​hole 310 of the front shell 300, press the snap-fit ​​part 200 to insert it into the hole. The connecting column 210 deforms outward due to external force, and the hook part 220 rebounds after passing the abutment part 311, locking with the abutment surface 3112, thus completing the fixation of the front shell 300 and the base shell 100. During disassembly, press the snap-fit ​​part 200 outward to deform it, and the hook part 220 disengages from the abutment surface 3112 and can be released from the snap-fit ​​hole 310, thus separating the front shell 300 from the base shell 100. In summary, after the base shell 100 is installed on the ceiling, the entire ceiling light can be quickly installed and removed by using the deformable snap-fit ​​part 200 in conjunction with the snap-fit ​​hole 310. In practical use, the faceplate 300 can be quickly disassembled and assembled without tools, which is convenient for lamp maintenance or lamp bead replacement. The elasticity of the connecting post 210 itself can provide a stable mechanical connection for the engagement of the snap-fit ​​part 200 and the snap-fit ​​hole 310, preventing loosening.

[0037] In some embodiments, the hook portion 220 is disposed toward the interior of the bottom shell 100, the abutment portion 311 is located on the side of the snap-fit ​​hole 310 near the interior of the top shell 300, the side of the abutment portion 311 away from the center of the top shell 300 is the limiting surface 3111, and the upper surface of the abutment portion 311 is the abutment surface 3112. When the snap-fit ​​portion 200 is inserted into the snap-fit ​​hole 310, the hook portion 220 and the limiting surface 3111 cooperate to deform the connecting post 210 toward the direction away from the center of the bottom shell 100; when the lower surface of the hook portion 220 abuts against the abutment surface 3112, the hook portion 220 and the abutment portion 311 are engaged. Specifically, when the snap-fit ​​part 200 is inserted, the hook part 220 contacts the inclined surface of the limiting surface 3111. The inclined surface guides the connecting post 210 to change shape, and the hook part 220 slides into the snap-fit ​​hole 310. After the hook part 220 is fully inserted, the connecting post 210 springs back, and the lower surface of the hook part 220 fits against the abutment surface 3112. The limiting surface 3111 cooperates with the connecting post 210 in the spring-back state to prevent the hook part 220 from falling out in the opposite direction.

[0038] Preferably, refer to Figure 4 The limiting surface 3111 is inclined, and along the insertion direction of the snap-fit ​​part 200, the limiting surface 3111 is inclined in a direction away from the center of the shell 300. The inclined limiting surface 3111 provides a smooth insertion path, avoids hard collision between the hook part 220 and the hole wall, and at the same time the deformation direction is controllable, ensuring the accuracy of the reset direction of the entire snap-fit ​​part 200.

[0039] In some embodiments, the bottom shell 100 is provided with a first mounting cylinder 110, and the top shell 300 is provided with a second mounting cylinder 320. A snap-fit ​​portion 200 is housed within the first mounting cylinder 110, and a snap-fit ​​hole 310 penetrates the second mounting cylinder 320. When the bottom shell 100 and the top shell 300 are assembled, the second mounting cylinder 320 is embedded within the first mounting cylinder 110. Specifically, after the top shell 300 is aligned with the bottom shell 100, the second mounting cylinder 320 is inserted into the first mounting cylinder 110, and the snap-fit ​​portion 200 extends into the snap-fit ​​hole 310 of the second mounting cylinder 320, causing the hook portion 220 and the abutment portion 311 to engage. Accordingly, the nesting of the first mounting cylinder 110 and the second mounting cylinder 320 provides radial positioning, ensuring precise alignment of the snap-fit ​​portion 200 with the snap-fit ​​hole 310.

[0040] In some embodiments, refer to Figure 4 The abutment surface 3112 is provided with at least one slot 3113, and the hook portion 220 is provided with at least one protrusion 221 on the side where it abuts the abutment surface 3112. When the abutment surface 3112 and the hook portion 220 abut, the protrusion 221 is embedded in the slot 3113, and they correspond one-to-one. In this embodiment, the interlocking structure of the protrusion 221 and the slot 3113 achieves anti-slip fixation through geometric shape matching. Preferably, in some embodiments, the slot 3113 is a concave spherical surface, and the shape of the protrusion 221 matches the shape of the slot 3113.

[0041] In some embodiments, refer to Figure 4 The edge of the faceplate 300 is provided with a mounting groove 340, and the edge of the bottom shell 100 is embedded in the mounting groove 340. Preferably, the edge of the bottom shell 100 is provided with a sealing groove 120, which is built into the mounting groove 340, and a waterproof silicone ring 121 is embedded in the sealing groove 120. The silicone ring seals to prevent moisture or dust from entering the lamp body.

[0042] In some embodiments, refer to Figure 5 The inner side of the faceplate 300 is provided with multiple heat dissipation ribs 140, and a heat dissipation gap 141 is provided between two adjacent heat dissipation ribs 140. The heat generated when the LED is working is conducted to the heat dissipation ribs 140 through the bottom shell 100, and the air flows in the gap to carry away the heat.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
