[0036] Embodiment One
[0037] Referring to Figure 1 The first embodiment of the present application discloses a light mixing structure 1 which can be used in a lamp.
[0038] Referring to Figure 1 and Figure 2 The light mixing structure 1 comprises a housing 11, a light source module 12, a convex lens 13 and a light diffusion plate 14. The light source module 12 is arranged inside the housing 11. The convex lens 13 is arranged inside the housing 11 and in front of the light source module 12. The light diffusion plate 14 is arranged in the housing 11 and in front of the convex lens 13. The front direction is the front direction of the irradiation direction of the light source module 12.
[0039] Specifically, the light source module 12 is arranged inside the housing 11 to emit original light. The convex lens 13 is arranged in front of the light source module 12 to converge the original light to enhance the light intensity in the center. The diffusion plate is arranged in front of the convex lens 13 to evenly spread the converged light.
[0040] In the embodiment of the present application, the convex lens 13 can converge the original light to enhance the light intensity in the center. The diffusion plate can evenly spread the converged light to achieve the effect of expanding the illumination range and uniform light. Finally, not only the light intensity in the center is enhanced, but also the illumination range is expanded and the uniform light effect is achieved. Therefore, the light mixing structure 1 provided by the present application effectively solves the problem that the lamp in the prior art cannot simultaneously satisfy the high light intensity in the center and the wide illumination range.
[0041] Optionally, the cross-sectional shape of the housing 11, the convex lens 13 and the diffusion plate is simultaneously any one of a polygon, a rectangle, a circle and an ellipse.
[0042] For the convenience of understanding, the present application will be described in detail with the cross-sectional shape of the housing 11, the convex lens 13 and the light diffusion plate 14 being a circle as an example, but the present application should not be limited thereto.
[0043] Further, referring to Figure 2 and Figure 3 The light source module 12 comprises at least one light emitter 121. The light emitter 121 is arranged at the geometric center of one end of the housing 11. The light emitted by the light emitter 121 is irradiated towards the other end of the housing 11.
[0044] Further, the shell 11 is a cylindrical structure, the light source module 12 and the light diffusion plate 14 are arranged at two ends of the shell 11, and the convex lens 13 is located between the light source module 12 and the light diffusion plate 14, and the middle of the convex lens 13 is convex towards the direction where the light diffusion plate 14 is located.
[0045] Specifically, the shell 11 is a circular cylindrical structure, and more specifically, an open-ended cylindrical structure. It can be understood that the light source module 12 and the light diffusion plate 14 are arranged at both ends of the open-ended cylindrical structure shell 11, and the convex lens 13 is arranged in the cylindrical structure shell 11 and located between the light source module 12 and the light diffusion plate 14.
[0046] Further, please refer to Figure 4 and Figure 5 It is shown that the inner wall of one end of the shell 11 forms a first clamping groove 111, the edge of the light diffusion plate 14 matches and connects with the first clamping groove 111, and the light source module 12 is arranged at the other end of the shell 11.
[0047] Further, the inner wall of the shell 11 forms a second clamping groove 112 at a predetermined distance from the first clamping groove 111, and the edge of the convex lens 13 matches and connects with the second clamping groove 112.
[0048] Specifically, the second clamping groove 112 is formed on the inner wall of the shell 11 at a predetermined distance from the first clamping groove 111, and the edge of the convex lens 13 matches and connects with the second clamping groove 112. More specifically, the predetermined distance position can be understood as any position between the light source module 12 and the light diffusion plate 14, as long as the convex lens 13 is arranged between the light source module 12 and the light diffusion plate 14, the convex lens 13 can converge the light emitted by the light source module 12 and then diffuse the converged light by the diffusion plate.
[0049] Specifically, by forming the first clamping groove 111 and the second clamping groove 112 on the inner wall of the shell 11, the light mixing structure 1 can be designed as a modular structure, which facilitates users to replace or upgrade the light source module 12 and the convex lens 13 according to actual needs, and improves the maintainability and expandability of the light mixing structure 1.
[0050] Further, the focal length of the convex lens 13 is a predetermined focal length, and the curvature of the convex lens 13 is a predetermined curvature.
[0051] Specifically, the focal length of the convex lens 13 determines the position of the focus point of the light rays after passing through the lens. In different lamps, the convex lens 13 is determined according to its application site and design requirements, and the focal length varies with factors such as lamp type, light source type, and required spot size, and cannot be given a unified range. Therefore, the utility model does not make specific limitation on the preset focal length here, as long as the convex lens 13 meets the function of converging the original light rays to enhance the illumination intensity of the center.
[0052] Specifically, the curvature of the convex lens 13 represents the degree of surface bending of the convex lens 13, and the curvature of the convex lens 13 has a direct impact on the degree of refraction of the light rays, and can determine the focusing effect of the light rays. Since in different lamp designs, factors such as light source type, focusing effect, required spot size, and light ray angle need to be considered to select the appropriate convex lens 13 curvature, a unified range cannot be given. Therefore, the utility model does not make specific limitation on the preset curvature here, as long as the convex lens 13 meets the function of converging the original light rays to enhance the illumination intensity of the center.
[0053] Optionally, the material of the convex lens 13 is any one of glass, plastic, and crystal.
[0054] Specifically, in different lamps, the material of the convex lens 13 needs to consider factors such as optical performance, durability, processing difficulty, and cost to meet the specific design requirements of the corresponding lamp. Therefore, the utility model does not make specific limitation on the material of the convex lens 13 here, as long as the convex lens 13 meets the function of converging the original light rays to enhance the illumination intensity of the center.
[0055] Further, the surface of the convex lens 13 is polished.
[0056] Specifically, the surface of the convex lens 13 is polished, first, it can make the surface smoother, reduce light scattering and irregular reflection, thereby improving the light transmittance of the lens and making the lamp brighter; second, it can remove the defects on the surface of the lens, improve the clarity of the image, and meet the needs of high-quality lighting occasions; third, the polished lens surface is harder and can resist scratches and wear, thereby prolonging the service life of the lens and the lamp.
[0057] Specifically, the convex lens 13 surface is coated with an anti-reflection coating, which can significantly reduce the reflection of light on the surface of the convex lens 13, thereby reducing the loss of light. In addition, by reducing reflection, the light transmittance of the lens can be increased, more light can pass through the lens, the lighting efficiency of the lamp can be improved, and the light transmittance and utilization efficiency can be improved.
[0058] Optionally, the light diffusion plate 14 is a multi-color diffusion plate, and the material of the light diffusion plate 14 is any one of polycarbonate, acrylic, polystyrene, and polyethylene terephthalate.
[0059] Specifically, the light diffusion plate 14 is a multi-color diffusion plate, and the material of the light diffusion plate 14 has its unique optical and weather-resistant properties, and is suitable for different environments and use scenarios. Since the diffusion plate needs to be selected according to the specific requirements and application scenarios, the material and size of the light diffusion plate 14 are not specifically limited in the utility model, as long as the light diffusion plate 14 can meet the requirement of uniformly spreading the converged light.
