[0011] Furthermore, to further optimize the reflection effect, the angle between the inner surface and the incident light direction is 40-50°.
[0012] Furthermore, in order to increase reflectivity and concentrate light, the reflective base surface of the mirror is a parabolic surface.
[0013] Furthermore, to optimize the reflection effect, the inner surface of the reflector is plated with aluminum.
[0014] Furthermore, in order to diffuse the light and make the illumination more uniform, the inner surface has a light distribution pattern or a light distribution texture.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0028] Example 1, such as Figure 1 As shown, an optical structure includes: a light source 1, a light-incident end 2, and a reflector 3.
[0029] Specifically, light source 1 is an LED, corresponding one-to-one with each lens, and light source 1 is located at the top. Light incident end 2 is located below light source 1, receiving light and refracting and focusing it before emission. Reflector 3 is located below light incident end 2, at an angle to the incident light, reflecting the light emitted from light incident end 2 before emission. For example... Figure 2 As shown, light enters from the light-inlet end 2, is refracted and focused by the light-inlet end 2, and then shines on the reflector 3 below. After being reflected by the reflector 3, it is emitted out.
[0030] Specifically, the light-incident end 2 includes multiple lenses connected in sequence, positioned above the reflecting mirror 3. In this example, the lenses are cup-shaped lenses to converge the light.
[0031] Preferably, in practical applications, the light-incident end 2 has a diffusion pattern structure or a diffusion texture structure, and the shape of the diffusion pattern structure or diffusion texture structure can be reasonably selected.
[0032] Specifically, the inner surface of the reflector 3 is plated with aluminum. The inner surface of the reflector 3 is beveled to increase reflectivity and change the direction of light propagation. Preferably, the angle between the inner surface and the incident light direction is 40-50°.
[0033] Preferably, in practical applications, the inner surface has a light-distributing pattern or light-distributing texture, which can diffuse the light and make the illumination more uniform. The shape of the light-distributing pattern or light-distributing texture can be reasonably selected.
[0034] Example 2 differs from Example 1 in that the inner surface of the reflector 3 is curved. The reflecting base surface of the reflector 3 is parabolic. Light rays incident on the reflector 3 are reflected by the reflector 3 and then emitted in parallel.
[0035] The backward extensions of the light rays received by reflector 3 converge at focal point F, which is the virtual focal point of the system. The relative relationship between the focal point of the LED and the virtual focal point of reflector 3 is designed according to actual requirements.
[0036] Example 3 differs from Example 1 in that the light-incident end 2 is a flat lens or a hyperbolic lens.
[0037] In Example 4, based on Example 1, a lampshade 4 is provided directly in front of the reflector 3. The lampshade 4 can be made of PMMA / PC or similar materials, and the color can be selected as needed. The surface of the lampshade 4 can be designed with light distribution patterns or textures.
[0038] In summary, the optical structure of this utility model, through the cooperation of the light-incident end and the reflector, refracts and focuses the light before horizontal reflection and emission, resulting in high light efficiency and uniform illumination.
[0039] The above description is based on the preferred embodiments of this utility model. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
