Description

Technical Field

[0001] This utility model relates to lighting devices, and more particularly to LED space lights. Background Technology

[0002] Space-age light panels are widely used lighting fixtures in large venues such as schools, office buildings, shopping malls, and hospitals. In existing technology, the installation and fixing structure of the various components within the light panel generally uses an intermediate transition piece. One end of the transition piece is locked to the first light panel assembly with a screw, and the other end is locked to the second light panel assembly with a screw, thus forming a connection between the first and second light panel assemblies. However, the aforementioned connection structure is aesthetically unappealing due to the exposed intermediate transition piece, and disassembly and assembly are inconvenient. During use, frequent disassembly is required for replacing lamps, maintenance, or other malfunctions. Currently, the commonly used methods are direct fixing or using spring clips or spring plates for clamping. The direct fixing method is very time-consuming and cumbersome during installation and removal.

[0003] Therefore, improving the ease of installation and disassembly of space light panels, as well as their safety and reliability after installation, are technical problems that need to be solved by those skilled in the art. Utility Model Content

[0029] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0030] Example 1, Reference Figures 1-11 This embodiment provides a space lamp, including a chassis 1, a diffuser 2, and a power supply box 3.

[0031] The diffuser hood 2 is mounted on the lower surface of the chassis 1. The lower surface of the chassis 1 is recessed inward in the direction away from the diffuser hood 2 to form a cavity 11. The two side walls of the cavity 11 along the width direction are mounting walls 12 connected to the diffuser hood 2.

[0032] The mounting wall 12 is provided with a plurality of inwardly recessed protrusions 121 and a screw hole at intervals along the length direction; the two sides of the diffuser hood 2 are placed in the cavity 11, and the two sides of the diffuser hood 2 are recessed in a direction that approaches each other to form a groove 21.

[0033] When the two sides of the diffuser hood 2 are placed in the recess 11, the protrusion 121 is placed in the groove 21 and is limited to the groove 21 in the direction of the diffuser hood 2 falling off. The bolt 122 passes through the screw hole and is limited to the groove 21 in the direction of the diffuser hood 2 falling off.

[0034] This allows the diffuser hood 2 to be fixedly connected to the chassis 1 on both sides by only one bolt 122. The function of the protrusion 121 is to pre-install and fix the diffuser hood 2 before connecting the screws, which facilitates the subsequent installation of the screws.

[0035] In this embodiment, an LED light source is provided at the bottom of the cavity 11, and the light emitted by the LED light source can be diffused out after passing through the diffuser 2. In order to achieve the diffusion effect, the diffuser 2 has a wavy protrusion on the side facing the LED light source.

[0036] In the above structure, the diffuser hood 2 is fixed to the chassis 1 from both sides along its width. To further increase the installation stability of the diffuser hood 2, end caps 13 are respectively provided at both ends of the cavity 11 along its length, and the two ends of the diffuser hood 2 along its length are placed in the end caps 13. In this way, the two ends of the diffuser hood 2 along its length are also fixed by the end caps 13, thus forming a stable connection.

[0037] To secure the end cap 13 to the chassis 1, in this embodiment, the outer wall of the end cap 13 is provided with an arc that fits against the two side walls of the recess 11, and the outer wall of the end cap 13 and the two side walls of the recess 11 are fixed together by a snap fastener. Specifically, the snap fastener 131 is provided on the outer wall of the end cap 13, and the two side walls of the recess 11 are provided with latches 111 that cooperate with the snap fastener 131.

[0038] To further secure the end cap 13, a mounting hole is provided at the bottom of the end cap 13, and a clearance opening is provided on the chassis 1 at the position corresponding to the mounting hole. The bolt 131 passes through the clearance opening and is fixedly connected to the mounting hole.

[0039] Furthermore, a space for accommodating the power supply box 3 is formed between the side wall of the chassis 1 and the side wall of the cavity 11; the side wall 31 of the power supply box 3 is connected to the side wall of the chassis 1 by a sliding connector, and an overlapping piece 32 extends horizontally outward from the top of the power supply box 3, overlapping the top of the cavity 11, and the overlapping piece 32 is fixed to the cavity 11 by bolts. The sliding connector includes a reinforcing rib 14 provided on the side wall of the chassis 1 and a socket 31 provided on the side wall of the power supply box 3. The connection between the chassis 1 and the power supply box 3 can be achieved by sliding.

[0040] In this embodiment, the chassis 1 is bent upward along both sides of the length direction to form the aforementioned sidewalls, and the inner surface of the sidewalls is fixedly connected to the shock-absorbing hooks 4.

[0041] The inner surface of the sidewall protrudes inward to form a channel 15 through which the pin portion 41 of the shockproof hook 4 passes. The inner surface of the sidewall is also provided with a wedge 16 that engages with the pin portion 41. The wedge 16 is located downstream of the channel 15 along the insertion direction of the pin portion.

[0042] The pin portion 41 is provided with a locking slot 411 for engaging with the wedge block 16. The wedge block 16 has an inclined surface.

[0043] When the stop pin passes through the channel 15 and interferes with the wedge 16, the inclined surface of the wedge 16 will cause the pin 41 to tilt upward and pass through the wedge 16. When the stop moves to the position of the bayonet 411 corresponding to the position of the wedge 16, the pin 41 and the wedge 16 are released from interference. The pin 41 is reset so that the wedge 16 is placed after the bayonet 411 to form a limiting fit.

[0044] Example 2

[0045] refer to Figure 12-13 The difference between this embodiment and Embodiment 1 is that the wedge 16 in Embodiment 1 is placed on the pin portion, and the portion of the pin portion 41 outside the channel 15 also forms a limiting surface 43. The limiting surface 43 is engaged with the other side wall of the channel 15 along the direction of insertion of the pin portion. The rest is the same as in Embodiment 1.

[0046] Example 3

[0047] refer to Figure 14-15 The difference between this embodiment and Embodiment 1 is that the wedge block is removed. Instead, a bent opening 42 is provided on the pin portion 41. After the pin portion 41 passes through the channel 15, it bends along the bent opening 42 and engages with one side wall of the channel 15 in a limiting engagement against the direction of pin insertion. The portion of the pin portion 41 outside the channel 15 also forms a limiting surface 43, which engages with the other side wall of the channel 15 in a limiting engagement along the direction of pin insertion.

[0048] In this embodiment, the bending opening 42 is a square opening. The shape of the bending opening is not limited to square; it can be any other shape as long as it can reduce the strength of the pin portion and allow it to be bent.

[0049] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
