A modular quick-release LED lighting fixture

Abstract

This utility model discloses a modular quick-release LED lighting fixture, including a lighting mechanism and a disassembly mechanism. The lighting mechanism includes a base plate, a bulb screwed onto the base plate, and a lampshade attached to the top of the base plate. The bulb is located inside the lampshade. The disassembly mechanism includes multiple plates installed on both sides of the lampshade, a U-shaped sleeve plate rotatably installed between two adjacent plates, a cross-shaped insert plate inserted into the U-shaped sleeve plate, and two limiting blocks fixed inside the U-shaped sleeve plate and engaging with the cross-shaped insert plate. In this utility model, when the bulb is damaged and needs to be replaced, the maintenance personnel push the U-shaped sleeve plate outward. After the limiting blocks separate from the cross-shaped insert plate, the cross-shaped insert plate naturally falls down. The lampshade, losing the support of the U-shaped sleeve plate and the cross-shaped insert plate, then contracts inward at the opening, reducing its volume and thus detaching from the base plate. This structure is simple and easy to disassemble.

Description

Technical Field

[0001] This utility model relates to the field of LED lighting fixture technology, specifically a modular quick-release LED lighting fixture. Background Technology

[0002] Lighting fixtures are devices that transmit, distribute, and alter the light distribution of a light source. This includes all components necessary for fixing and protecting the light source, excluding the light source itself, as well as the necessary wiring accessories for connection to a power source. Lighting fixtures can be classified according to their design, such as chandeliers, ceiling lights, floor lamps, wall lamps, table lamps, and decorative candles.

[0003] To ensure lighting effects and user comfort, most light fixtures are installed on the ceiling. To prevent accidents caused by falling, the installation of light fixtures must be secure and reliable. However, this also makes it difficult to quickly disassemble and reassemble the light fixtures, which hinders later maintenance and repair. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A modular quick-release LED lighting fixture includes a lighting mechanism and a spreading mechanism. The lighting mechanism includes a base plate, a bulb screwed to the base plate, and a lampshade attached to the top of the base plate. The bulb is disposed inside the lampshade. The spreading mechanism includes multiple plates installed on both sides of the lampshade, a U-shaped sleeve plate rotatably installed between two adjacent plates, a cross-shaped insert plate inserted into the U-shaped sleeve plate, and two limiting blocks fixed inside the U-shaped sleeve plate and engaging with the cross-shaped insert plate. The outer end of the cross-shaped insert plate is rotatably installed between two adjacent plates.

[0007] By adopting the above technical solution, when the bulb is damaged and needs to be replaced, the maintenance personnel push the U-shaped sleeve outward. After the limiting block separates from the cross plate, the cross plate hangs down naturally. The lampshade, which loses the support of the U-shaped sleeve and the cross plate, then shrinks inward at the opening, becomes smaller, and then separates from the base plate. The structure is simple and easy to disassemble.

[0008] In a preferred embodiment, the present invention can be further configured such that the lampshade consists of a protective shell and two edges, the two edges being fixed to both sides of the protective shell respectively.

[0009] In a preferred embodiment, the present invention can be further configured such that: openings are provided on both sides of the protective shell, and the openings are located between the two edges.

[0010] In a preferred embodiment, the present invention can be further configured as follows: multiple plates are arranged in pairs, forming four groups, and the four groups of plates are respectively fixed to the inner side walls of the two openings.

[0011] In a preferred embodiment, the present invention can be further configured such that the U-shaped sleeve is made of shape memory metal material and the cross insert is made of alloy material.

[0012] In a preferred embodiment, the present invention can be further configured such that two limiting blocks fixed inside the U-shaped sleeve are vertically symmetrical about the cross insert, and the limiting blocks are rectangular.

[0013] In a preferred embodiment, the present invention can be further configured such that: a plurality of threaded holes are formed on the substrate, and the plurality of threaded holes are arranged in pairs, forming four groups, with the four groups of threaded holes located at the four corners of the substrate respectively.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0015] 1. In this utility model, when the bulb is damaged and needs to be replaced, the repairman moves the U-shaped sleeve outward. After the limiting block separates from the cross plate, the cross plate hangs down naturally. The lampshade, which loses the support of the U-shaped sleeve and the cross plate, then shrinks inward at the opening, becomes smaller, and then separates from the base plate. This structure is simple and easy to disassemble.

[0016] 2. In this utility model, a U-shaped sleeve plate is made of shape memory metal material to ensure that the U-shaped sleeve plate can restore its shape after being opened. Then, the cross plate made of alloy material has high hardness and can stably support the inner wall of the opening, thereby increasing the reusability of the opening mechanism and reducing the cost of using the lampshade.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0027] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0028] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a modular quick-release LED lighting fixture.

[0029] Example 1:

[0030] Combination Figure 1-5 As shown, the present invention provides a modular quick-release LED lighting fixture, including a lighting mechanism 100 and a support mechanism 200. The lighting mechanism 100 includes a substrate 110, a bulb 120 screwed to the substrate 110, and a lampshade 130 attached to the top of the substrate 110. The bulb 120 is disposed inside the lampshade 130.

[0031] The opening mechanism 200 includes multiple plates 210 installed on both sides of the lampshade 130, a U-shaped sleeve plate 220 rotatably installed between two adjacent plates 210, a cross-shaped insert plate 230 inserted into the U-shaped sleeve plate 220, and two limiting blocks 240 fixed inside the U-shaped sleeve plate 220 and engaged with the cross-shaped insert plate 230. The outer end of the cross-shaped insert plate 230 is rotatably installed between two adjacent plates 210.

[0032] Furthermore, the lampshade 130 is composed of a protective shell 131 and two edges 132, with the two edges 132 respectively fixed to both sides of the protective shell 131. The shape design of the lampshade 130 provides conditions for snapping with the substrate 110.

[0033] Furthermore, the protective shell 131 has openings 133 on both sides, and the openings 133 are located between the two edges 132. The openings 133 provide conditions for the installation of the support mechanism 200, ensuring that the protective shell 131 can increase its volume under the support of the U-shaped sleeve plate 220 and the cross insert plate 230, and then be snapped into the base plate 110.

[0034] Furthermore, the multiple plates 210 are arranged in pairs, forming four groups. The four groups of plates 210 are respectively fixed to the inner side walls of the two openings 133. The layout design of the plates 210 ensures that the U-shaped sleeve plate 220 and the cross insert plate 230 can be smoothly inserted.

[0035] Furthermore, the two limiting blocks 240 fixed inside the U-shaped sleeve 220 are vertically symmetrical about the cross insert 230. The limiting blocks 240 are rectangular. The shape design of the limiting blocks 240 ensures that the cross insert 230 will not rotate upward or downward after it is connected to the U-shaped sleeve 220.

[0036] Example 2:

[0037] Combination Figure 1 , 4 and Figure 5 As shown, based on Embodiment 1, the U-shaped sleeve 220 is made of shape memory metal material and the cross insert 230 is made of alloy material. Using shape memory metal material to make the U-shaped sleeve 220 ensures that the U-shaped sleeve 220 can restore its shape after being opened, realizing the reuse of the U-shaped sleeve 220. Then, the cross insert 230 made of alloy material has high hardness and can stably support the inner wall of the opening 133.

[0038] Example 3:

[0039] Combination Figure 1-2 As shown, in the above embodiment, the substrate 110 is provided with a plurality of threaded holes 300, which are arranged in pairs to form four groups. The four groups of threaded holes 300 are located at the four corners of the substrate 110 respectively. The threaded holes 300 provide conditions for the substrate 110 to be firmly connected to the ceiling.

[0040] The working principle and usage process of this utility model are as follows: In the initial state, the cross plate 230 and the U-shaped sleeve plate 220 are inserted into each other, and the upward / downward rotation is restricted by the limiting block 240. At this time, the cross plate 230 and the U-shaped sleeve plate 220 cooperate to open the lamp cover 130, so that the edge 132 of the lamp cover 130 is engaged with the top of the substrate 110. When the bulb 120 is damaged and needs to be replaced, the maintenance personnel push the U-shaped sleeve plate 220 outward. After the limiting block 240 separates from the cross plate 230, the cross plate 230 hangs down naturally. The lamp cover 130, which loses the support of the U-shaped sleeve plate 220 and the cross plate 230, then shrinks inward at the opening 133, becomes smaller, and then separates from the substrate 110. This structure is simple and easy to disassemble.

[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
