In order to solve the above problems, we have developed a lamp with multi-lens composite prism refraction and uniform light output. Utility Model Content

[0003] The technical problem to be solved by the purpose of the utility model is to provide a lamp with multi-lens composite prism refraction and uniform light output, which is output after multiple light oscillations and refractions through different lens plates, and multiple lens light beams are divided into multiple fine light beams for illumination. The slight unevenness within the range of each fine light beam is compensated due to the mutual superposition of fine light beams in symmetrical positions, so that the light energy in the entire aperture is effectively and evenly utilized. Each small lens of the compound eye lens overlaps the small lens corresponding to the first compound eye lens to form an image on the lighting surface, further ensuring the uniform distribution of light. The more partitions of the compound eye lens, the higher the uniformity of the light, and the more delicate the picture.

Through the fly's eye lens, the microscope can magnify small objects, so that the human eye can see finer details. The tiny unevenness within the range of each fine beam is compensated by the mutual superposition of the fine beams in symmetrical positions, so that the light energy in the entire aperture is effectively and evenly utilized. Each small lens of the compound eye lens overlaps the small lens corresponding to the first compound eye lens and forms an image on the illumination surface, further ensuring the uniform distribution of light.

The light emitted by the lamp body is refracted multiple times through the fly-eye lens surface 2, the compound-eye lens surface 3, the Hartmann microlens array 4 and the prism surface 5 to make the light uniform and anti-glare and brighten the output.

[0020] The lamp body 1 includes a tube lamp housing 11, an LED lamp board 12, a bottom reflector 13 and a side ring reflector 14; the bottom reflector 13 is provided with a hole 131 corresponding to the position of the lamp beads on the LED lamp board 12. The fly eye lens surface 2 and the compound eye lens surface 3 are provided on the same or different lenses. As shown in Figures 1 and 2, the fly eye lens surface 2 is located on the bottom surface, and the compound eye lens surface 3 is located on the top surface. The shape of the lamp body 11 can be circular, elliptical or polygonal.

[0021] The Hartmann microlens array 4 and the prism surface 5 are respectively arranged on different lenses, and the lens of the Hartmann microlens array 4 is between the fly-eye lens surface 3 and the prism surface 5. The fly-eye lens surface 2, the fly-eye lens surface 3, the Hartmann microlens array 4 and the prism surface 5 are formed on a lens made of a transparent plastic lens, a transparent soft gel lens, a transparent glass lens or the like.

[0022] A variation that requires further explanation: In different implementations, the fly-eye lens surface 2, the compound-eye lens surface 3, the Hartmann microlens array 4 and the prism surface 5 are formed on the first lens (on the same lens); for example, in a specific implementation, the Hartmann microlens array 4 and the prism surface 5 can be arranged on the upper surface of the first lens; the fly-eye lens surface 2, the compound-eye lens surface 3, the Hartmann microlens array 4 and the prism surface 5 are arranged on the lower surface of the first lens.

Through the fly-eye lens, the microscope can magnify small objects, so that the human eye can see more subtle details. The tiny unevenness within the range of each fine beam is compensated by the mutual superposition of the fine beams in the symmetrical position, so that the light energy in the entire aperture is effectively and evenly utilized. Each small lens of the compound eye lens overlaps the small lens corresponding to the first compound eye lens and forms an image on the illumination surface, further ensuring the uniform distribution of light. The more partitions of the compound eye lens, the higher the uniformity of the light, and the more delicate the picture.

This feature makes microlenses widely used in laser systems, optical communications, optical sensing and other fields. In laser systems, microlenses can be used to control the shape and size of the laser beam, thereby achieving efficient focusing and output of the laser, which will also affect the uniform light effect of the compound eye lens, the characteristics of uniform light brightening and anti-glare, and simple structure, quick installation, low production cost, anti-glare and anti-glare, giving users a good visual experience.
