[0019] The present invention will be further described below with reference to the embodiments.
[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.
[0021] Please see Figure 1-4This utility model provides a uniformly illuminating LED lighting source, including a mounting housing 1. An LED lamp 2 is fixedly installed inside the mounting housing 1. An adjustment component 3 adapted to the LED lamp 2 is provided inside the mounting housing 1. The adjustment component 3 includes a connecting ring 301, an adjustment groove 302, a mounting ring frame 303, a plano-convex lens 304, a limiting slide groove 305, a limiting slider 306, a toggle post 307, a rotating ring 308, a pushing ring 309, and an arc-shaped groove 3010. The connecting ring 301 is threaded into the inside of the mounting housing 1, and the adjustment groove 302 is formed in the connecting ring 301. The inner wall of the inner ring is supported by a mounting ring frame 303 movably mounted inside an adjusting groove 302. A plano-convex lens 304 is fixedly mounted inside the mounting ring frame 303. A limiting slide groove 305 is formed on the inner wall of the adjusting groove 302. A limiting slider 306 is fixedly connected to the outer ring side surface of the mounting ring frame 303. A toggle post 307 is fixedly connected to the side of the limiting slider 306 away from the mounting ring frame 303. A rotating ring 308 is threadedly connected to the outer surface of the mounting housing 1. A pushing ring 309 is fixedly connected to one end of the rotating ring 308. An arc-shaped groove 3010 is formed on the inner wall of the inner ring of the pushing ring 309. This component is provided with overall support and protection by the mounting housing 1, and an internally fixed LED light 2 serves as the light source. The connecting ring 301 in the adjustment assembly 3 is securely connected to the mounting housing 1 via a threaded connection, facilitating disassembly and maintenance. The adjustment groove 302 provides movement space for the mounting ring frame 303. The plano-convex lens 304 can refract and adjust the light emitted by the LED lamp 2, improving the uniformity of illumination. The cooperation between the limiting slide groove 305 and the limiting slider 306 ensures that the mounting ring frame 303 moves smoothly and does not derail. The cooperation between the actuating column 307 and the arc groove 3010 allows the pushing ring 309 to drive the actuating column 307 through the arc groove 3010 when the rotating ring 308 rotates, thereby driving the mounting ring frame 303 to move within the adjustment groove 302, realizing the adjustment of the distance between the plano-convex lens 304 and the LED lamp 2 to adapt to different illumination requirements.
[0022] In this invention, when used in different rooms, the reflector cup 4 first concentrates the light from the LED lamp 2 onto the surface of the plano-convex lens 304, and then the adjustment component 3 changes the refraction angle of the plano-convex lens 304 on the light, effectively eliminating blind spots and differences in brightness, achieving a uniform lighting effect. Without replacing the lamps, it can meet the lighting needs of various rooms, greatly improving the convenience and flexibility of use, and providing high-quality and suitable lighting conditions for different spaces.
[0023] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, a reflector cup 4 is fixedly installed on the outside of the LED light 2. A threaded groove 5 is provided on the inner wall of the reflector cup 4 in front of it and inside the mounting housing 1. A threaded groove 7 is provided on the outer surface of the mounting housing 1.
[0024] The outer surface of the connecting ring 301 has a threaded groove 2 6, and the inner wall of the inner ring of the rotating ring 308 has a threaded groove 4 8. The reflector cup 4 reflects and focuses the light emitted by the LED lamp 2 to enhance the lighting effect; the threaded groove 1 5 on the inner wall of the mounting housing 1 is adapted to the threaded groove 2 6 on the outer side of the connecting ring 301 to achieve a stable and detachable connection; the threaded groove 3 7 on the outer side of the mounting housing 1 is adapted to the threaded groove 4 8 on the inner wall of the rotating ring 308 to allow the rotating ring 308 to rotate smoothly, providing a power transmission structure for the adjustment component 3, and together ensuring the stable installation and adjustment function of the light source.
[0025] Specifically, such as Figure 1 and Figure 2 As shown, an anti-slip strip 9 is fixedly connected to the outer surface of the rotating ring 308, and a transparent glass 10 is fixedly installed inside the opening of the connecting ring 301. The anti-slip strip 9 increases the friction on the outer side of the rotating ring 308, making it easier for operators to operate with less effort; the transparent glass 10 protects the internal components from contamination and damage, while ensuring that light can pass through smoothly without affecting the lighting effect.
[0026] Specifically, such as Figure 2 and Figure 3 As shown, the shapes of thread groove 1 5 and thread groove 2 6 are adapted to each other, and the shapes of thread groove 3 7 and thread groove 4 8 are adapted to each other. The adapted design of thread groove 1 5 and thread groove 2 6, and thread groove 3 7 and thread groove 4 8 respectively ensures the stability of the connection between the connecting ring 301 and the mounting housing 1 and the rotating ring 308 and the mounting housing 1, and provides a guarantee for the reliability of the overall structure of the light source.
[0027] The end of the actuating post 307 away from the limiting slider 306 is located inside the arc-shaped groove 3010. The plano-convex lens 304 has a convex surface on the side closer to the LED lamp 2 and a flat surface on the side away from the LED lamp 2. The movement of the actuating post 307 within the arc-shaped groove 3010 realizes the power transmission for the rotating ring 308 to rotate to the position adjustment of the plano-convex lens 304. The structural design of the plano-convex lens 304 with its convex surface facing the LED lamp 2 makes the light distribution more uniform after refraction, effectively reducing the dark corners and differences in brightness, and significantly improving the uniformity of illumination.
[0028] Working principle and usage process of this utility model:
[0029] When the staff needs to adjust the uniformity of the light of LED light 2, they first apply rotational force through the anti-slip strip 9 on the outside of the rotating ring 308. Since the threaded groove 4 8 on the inner wall of the rotating ring 308 cooperates with the threaded groove 3 7 on the outside of the mounting housing 1, the rotational force is converted into axial displacement and drives the push ring 309 to rotate synchronously.
[0030] At this time, the arc groove 3010 of the inner ring of the push ring 309 and the actuating column 307 generate relative movement. Since the actuating column 307 is fixed on the limiting slider 306, and the limiting slider 306 can only slide linearly in the limiting slide groove 305 on the inner wall of the adjusting groove 302, the curved trajectory of the arc groove 3010 forces the actuating column 307 to drive the mounting ring 303 to move axially, thereby changing the distance between the plano-convex lens 304 and the LED lamp 2.
[0031] As the position of the plano-convex lens 304 changes, the refraction angle of the light emitted from the LED lamp 2 changes when it passes through the plano-convex lens 304: when the plano-convex lens 304 is closer to the LED lamp 2, the refraction angle increases and the light field distribution range widens; when the plano-convex lens 304 is farther away from the LED lamp 2, the refraction angle decreases and the light field distribution tends to be concentrated. At the same time, the reflector cup 4 on the outside of the LED lamp 2 reflects and focuses the lateral light, which works synergistically with the refraction effect of the plano-convex lens 304 to optimize the light intensity distribution.
[0032] Ultimately, the light output through the transparent glass 10 creates a uniform and adjustable lighting effect in the target area. Throughout the process, the connecting ring 301 is fixed to the threaded groove 5 on the inner wall of the mounting housing 1 via the threaded groove 2 6, providing stable support for the adjustment mechanism and ensuring the reliability of the adjustment process.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
