Description

Technical Field

[0001] This disclosure relates to the technical field of lighting fixtures, and in particular to a modular lighting fixture. Background Technology

[0002] Downlights are installed on the ceiling to provide indoor lighting. Existing downlights generally adopt a structure that integrates the lamp body, light source module, and driver circuit into one unit to achieve a high degree of integration.

[0003] When a single component of a downlight malfunctions, the entire downlight needs to be disassembled and maintained, which is cumbersome and costly. When users need to adjust the lighting effect according to a specific spatial atmosphere or function, adjusting the downlight's lighting effect requires replacing the entire downlight, which cannot meet the need for quick adaptation of the lighting effect to different lighting scenarios.

[0004] For example, the integrated ceiling downlight disclosed in prior art document CN201721116021.5 includes a downlight lens, a downlight light source, a plastic housing, a spring clip, a spotlight lens, a spotlight light source, and a cold-forged heat sink. The plastic housing includes an outer ring and an inner ring. The spotlight lens is embedded in the bottom of the inner ring of the plastic housing, and the spotlight light source is attached to the center of the small port of the spotlight lens. The plastic housing, spotlight lens, and spotlight light source are fixed to the cold-forged heat sink. The downlight light source is placed in the middle of the outer and inner rings of the plastic housing, and then the annular downlight lens is placed on top. This ceiling downlight solution has an integrated structure. When the light source fails, the entire ceiling downlight needs to be removed, which is troublesome to maintain. In addition, the light source illumination effect is monotonous and cannot flexibly adapt to diverse scene requirements. Utility Model Content

[0029] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0030] like Figures 1 to 3 As shown, this is a modular lighting fixture 10 according to an embodiment of the present disclosure, including a base module structure 100 and a lamp body module structure 200. Please refer to 4 as well. The base module structure 100 includes a base shell assembly 110 and a conductive sheet assembly 120. The base shell assembly 110 has a receiving cavity 1101. The conductive sheet assembly 120 is installed in the receiving cavity 1101. One end of the base shell assembly 110 has a circular conductive groove 1102 communicating with the receiving cavity 1101. The conductive connection end of the conductive sheet assembly 120 is disposed in the circular conductive groove 1102. The base shell assembly 110 has two swivel grooves 1103 symmetrically arranged along the axis of the circular conductive groove 1102.

[0031] Furthermore, the lamp body module structure 200 includes a lamp housing assembly 210, a light source assembly 220, and a power supply board assembly 230. The lamp housing assembly 210 includes a mounting groove 2101. The light source assembly 220 is installed in the mounting groove 2101. For example, the light source assembly 220 is detachably connected to the inner wall of the mounting groove 2101. The power supply board assembly 230 is partially disposed in the mounting groove 2101. One end of the power supply board assembly 230 is electrically connected to the light source assembly 220, and the other end of the power supply board assembly 230 is embedded in the circular conductive groove 1102 and electrically connected to the conductive sheet assembly 120. The lamp housing assembly 210 has two inverted fasteners 211 protruding from one end adjacent to the base housing assembly 110, which are symmetrically arranged along the axis of the power supply board assembly 230. Each inverted fastener 211 is fastened to the corresponding rotating groove 1103.

[0032] In this embodiment, the base housing assembly 110 fixes the conductive sheet assembly 120 through the receiving cavity 1101. The conductive connection end of the conductive sheet assembly 120 is set in the circular conductive groove 1102 to form a standardized electrical interface. Two inverted fasteners 211 arranged symmetrically on the lamp housing assembly 210 rotate and fasten along the screw fastening groove 1103 to complete the quick locking and installation of the base module structure 100 and the lamp body module structure 200. One end of the power board assembly 230 on the lamp housing assembly 210 is electrically connected to the light source assembly 220, and the other end is embedded in the circular conductive groove 1102 of the base module to form an electrical path with the conductive sheet assembly 120. The control signal received and transmitted by the power board assembly 230 drives the light source assembly 220 to emit light of different color temperatures. The emitted light is refracted and reflected after passing through the lamp housing assembly 210, so that the controlled light obtains a specific light illumination effect after passing through the lamp housing assembly 210. By adjusting the source assembly 220 and the lamp housing assembly 210, the lamp body module structure 200 can obtain different illumination effects.

[0033] The aforementioned modular lighting fixture 10 can be mechanically fixed by rotating the buckle 211 and the swivel groove 1103, without the need for additional screws or complex wiring operations. This improves the speed of disassembly and assembly of the base module structure 100 and the lamp body module structure 200 and increases installation efficiency, ensuring reliable electrical connection between the power pin and the conductive plate in the circular conductive groove 1102. The modular lighting fixture 10 consists of a base module structure 100 and a lamp body module structure 200. The base module structure 100 does not need to be changed after it is fixedly installed, making it convenient to replace and maintain the lamp body module structure 200. The base module structure 100 is compatible with the installation of lamp body module structures 200 with different illumination effects, thereby adapting to the needs of diverse scene illumination effects.

[0034] like Figure 3 and Figure 4As shown, in one embodiment, the base housing assembly 110 includes an inner base housing 111, an insulating support 112, and an outer base housing 113. The outer base housing 113 is fitted onto the inner base housing 111. The insulating support 112 is disposed between the inner base housing 111 and the outer base housing 113. The insulating support 112 has a support through hole 1104. The outer base housing 113 also has a power-conducting hole 1105. The inner base housing 111 has a terminal mounting slot 1106. The support through hole 1104 is connected to both the power-conducting hole 1105 and the terminal mounting slot 1106. In this embodiment, the layered structure of the inner base housing 111, the insulating support 112, and the outer base housing 113 isolates the internal conductive sheet assembly 120. The wiring channel formed by the power-conducting hole 1105, the support through hole 1104, and the terminal mounting slot 1106 standardizes the wiring of electrical circuits, thereby reducing potential safety hazards in the circuit.

[0035] like Figure 3 and Figure 4 As shown, in one embodiment, the base housing assembly 110 further includes a terminal block 114. The bottom of the bracket through-hole 1104 is beveled, and the terminal mounting groove 1106 communicates with the side wall of the bracket through-hole 1104. The terminal block 114 is installed in the terminal mounting groove 1106 and is electrically connected to the conductive sheet assembly 120. In this embodiment, the support bracket is embedded between the inner base housing 111 and the outer base housing 113. The bottom of the bracket through-hole 1104 is designed with a beveled structure, and the terminal block 114 is installed in the terminal mounting groove 1106 through the side wall. This facilitates terminal block installation, optimizes space layout, and improves space utilization.

[0036] like Figure 4 As shown, in one embodiment, the conductive sheet assembly 120 includes a drive plate 121, a first conductive sheet 122, and a second conductive sheet 123. The drive plate 121 is clamped between the insulating bracket 112 and the base housing 113.

In this embodiment, the first conductive sheet 122 and the second conductive sheet 123 are installed independently and can carry positive and negative currents respectively. The first conductive sheet 122 and the second conductive sheet 123 are fixed by a preset slot or screw in the insulating bracket 112 so that the contact ends of the first conductive sheet 122 and the second conductive sheet 123 are disposed in the circular conductive groove 1102.

[0037] like Figure 4As shown, in one embodiment, the inner shell 111 of the base has a conductive hole 1107 and an annular conductive groove 1108. The conductive hole 1107 is disposed within the annular conductive groove 1108. The contact end of the first conductive piece 122 is disposed in the conductive hole 1107, and the contact end of the second conductive piece 123 is disposed in the annular conductive groove 1108. In this embodiment, the circular conductive groove 1102 of the outer shell 113 of the base is divided into a conductive hole 1107 and an annular conductive groove 1108. The conductive hole 1107 is located at the center of the annular conductive groove 1108, forming a concentric circle structure. The contact end of the first conductive piece 122 is embedded in the conductive hole 1107, and the contact end of the second conductive piece 123 is embedded in the annular conductive groove 1108, thereby achieving electrical isolation and independent conduction.

[0038] like Figure 3 and Figure 5 As shown, in one embodiment, the lamp housing assembly 210 includes a connecting panel 212, a connecting housing 213, and a lampshade component 214. A buckle 211 protrudes from one side of the connecting panel 212, and the lampshade component 214 is connected to the side of the connecting housing 213 opposite to the buckle 211. The connecting panel 212 and the lampshade component 214 form the mounting groove 2101, and the connecting housing 213 is disposed within the mounting groove 2101 and connected to the connecting panel 212. In this embodiment, the connecting panel 212, the connecting housing 213, and the lampshade component 214 form a rigid structure through a layered nesting design, enhancing the deformation resistance of the lamp housing assembly 210. The lampshade component 214 is connected to the connecting housing 213 via snap-fit ​​or threaded connections, ensuring stable connection after long-term use. The lampshade component 214 can be made of a light-transmitting material, frosted glass, or a reflective surface structure to achieve uniform light, focused light, or anti-glare effects, adapting to different lighting scenarios.

[0039] like Figure 3 As shown, in one embodiment, the power board assembly 230 includes a conductive pin 231 and a circuit board 232. A limiting groove 2102 is formed between the connecting panel 212 and the connecting housing 213. The circuit board 232 is mounted in the limiting groove 2102. The connecting panel 212 has a power connection hole 2103, and the conductive pin 231 passes through the power connection hole 2103 to be electrically connected to the circuit board 232. In this embodiment, the conductive pin 231 includes a positive pin and an annular negative pin. The power connection hole 2103 is located at the center of the connecting panel 212. The conductive pin 231 passes through the power connection hole 2103. The positive pin and the annular negative pin are respectively aligned with the conductive hole 1107 and the annular conductive groove 1108 of the base module for electrical connection. During the rotation and fastening process, the contact pressure between the conductive pin 231 and the conductive sheet assembly 120 gradually increases to ensure reliable electrical conduction.

[0040] like Figure 3 As shown, in one embodiment, the light source assembly 220 includes a light source 221 and a lens 222. The light source 221 is fixed to the side of the connecting housing 213 opposite to the connecting panel 212. The lampshade 214 has a lens groove 2104, and the lens 222 is installed in the lens groove 2104. The lens 222 is located in the light emission direction of the light source 221. In this embodiment, the light source assembly 220 emits light after being powered by the conductive pin 231 and the circuit board 232. After being refracted or reflected by the lens 222, the light is directionally projected onto a designated area through the light-transmitting area of ​​the lampshade 214. Different light sources 221 and different lenses 222 can form lamp modules with different power, color temperature, or beam angle to meet the needs of different lighting effects in different scenarios.

[0041] like Figure 5 As shown, in one embodiment, the lampshade 214 is fastened to the connecting panel 212, and the side of the lampshade 214 facing away from the connecting panel 212 forms a conical arc surface. In this embodiment, the conical arc surface formed on the side of the lampshade 214 facing away from the connecting panel 212 can soften the light and improve visual comfort; at the same time, the conical arc surface can serve as a decorative surface, enhancing the aesthetics of the product.

[0042] like Figure 4 As shown, in one embodiment, the base housing assembly 110 has two symmetrically arranged mounting through holes 1109. In this embodiment, the two symmetrically designed mounting through holes 1109 allow the base module assembly 100 to be quickly fixed to the mounting surface through two-point positioning, reducing installation deviation.

[0043] Compared with the prior art, this disclosure has at least the following advantages:

[0044] The aforementioned modular lighting fixture 10 can be mechanically fixed by rotating the buckle 211 and the swivel groove 1103, without the need for additional screws or complex wiring operations. This improves the speed of disassembly and assembly of the base module structure 100 and the lamp body module structure 200 and increases installation efficiency, ensuring reliable electrical connection between the power pin and the conductive plate in the circular conductive groove 1102. The modular lighting fixture 10 consists of a base module structure 100 and a lamp body module structure 200. The base module structure 100 does not need to be changed after it is fixedly installed, making it convenient to replace and maintain the lamp body module structure 200.
