[0002] LED lighting, or light-emitting diode lighting, is a type of semiconductor solid-state light-emitting device. It uses a solid semiconductor chip as the light-emitting material. In the semiconductor, excess energy is released through the recombination of charge carriers, causing photon emission and directly emitting red, yellow, blue, and green light. Building upon this, by adding phosphors based on the three primary color principle, any color of light can be emitted. Lighting fixtures made using LEDs as the light source are called LED lamps.

[0019] Example 1

[0020] like Figures 1-3 As shown, the modular LED lens combination lighting device proposed in this embodiment includes a lamp housing 1, a first annular housing 51 and a second annular housing 52.

[0021] A circuit board 2 and a lamp bead mounting plate 3 are installed on the inner side of the lamp housing 1. Multiple LED beads 4 are installed on the lamp bead mounting plate 3, and the LED beads 4 are electrically connected to the circuit board 2. A silver coating is provided on the side of the lamp bead mounting plate 3 adjacent to the LED beads 4. The silver coating has a good reflective effect and can prevent light from being absorbed by the lamp bead mounting plate 3, thereby further improving the utilization rate of the light source. A first reflective arc surface 1001 is provided on the inner wall of the lamp housing 1 adjacent to the LED beads 4.

[0022] The lamp housing 1 has multiple heat dissipation holes, and dustproof mesh 9 is installed on the inside of each heat dissipation hole.

[0023] The first annular housing 51 and the second annular housing 52 are detachably installed at both ends of the lamp housing 1. A threaded ring 8 is connected to the side of the first annular housing 51 and the second annular housing 52 adjacent to the lamp housing 1. Annular grooves 101 are provided at both ends of the lamp housing 1. A threaded portion adapted to the threaded ring 8 is provided inside the annular groove 101. The threaded ring 8 is aligned with the annular groove 101 and rotated. The threaded portion allows the first annular housing 51 and the second annular housing 52 to be threadedly connected to the lamp housing 1, facilitating disassembly. A direct-projection lens 71 and a diffuser lens 72 are respectively installed inside the first annular housing 51 and the second annular housing 52. A second reflective arc surface 501 is provided on the inner wall of both the first annular housing 51 and the second annular housing 52. Tempered glass mirrors 6 are installed on the outer sides of both the first annular housing 51 and the second annular housing 52. The tempered glass mirrors 6 prevent scratches on the lens surface.

[0024] Specifically, this technical solution involves detachably installing a first annular housing 51 and a second annular housing 52 on both sides of the lamp housing 1. A convex lens 71 and a concave lens 72 are installed on the inner sides of the first annular housing 51 and the second annular housing 52, respectively, allowing for switching between the convex lens 71 and the concave lens 72 to change the degree of light scattering and meet the needs of different environmental scenarios. Furthermore, this technical solution maximizes the size of the emitted light source while allowing for lens switching, thus meeting the requirements of high-intensity illumination. When the LED bead 4 emits light, the light source is emitted outward through the convex lens 71 and the concave lens 72. The first reflective arc surface 1001 concentrates the optical fiber reflected onto the inner wall of the lamp housing 1, resulting in concentrated light emission. The second reflective arc surface 501 also aims to converge the light refracted outward through the lens inward, avoiding excessive light scattering and improving light utilization.

[0025] Example 2

[0026] like Figure 1 As shown, this embodiment of the modular LED lens combination lighting device, compared with the first embodiment, further includes an installation component. The installation component includes a wall-mounted support 12, a spherical cover 13, a connecting elbow 10, and a sphere 11. The connecting elbow 10 is connected to the lamp housing 1, the sphere 11 is connected to the end of the connecting elbow 10, and the spherical cover 13 is mounted on the wall-mounted support 12. The wall-mounted support 12 is fixed to the cavity or other mounting surface by expansion screws. The sphere 11 and the spherical cover 13 are connected by a movable structure. Damping rubber is installed on the inner wall of the spherical cover 13, and the damping rubber tightly covers the outer surface of the sphere 11. Specifically, the sphere 11 is snapped into the inner side of the spherical cover 13 and can be rotatably connected to the spherical cover 13, so that the lighting device can be adjusted at multiple angles to meet its different illumination needs, making it highly adaptable.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
