Description

Technical Field

[0001] This utility model relates to a lamp with a transparent double-layer Fresnel fly-eye optical lens. Background Technology

[0002] According to patent searches and market research, existing lamps have light-emitting surfaces directly on the tube body or its surface, resulting in poor light uniformity and low light utilization. Furthermore, direct illumination from the light-emitting surface can cause glare and discomfort. Existing lamp structures are also complex, costly, and inconvenient to install. Therefore, we have developed a lamp with a transparent double-layer Fresnel fly-eye optical lens. Utility Model Content

[0003] The technical problem this invention aims to solve is to provide a lamp with a transparent double-layer Fresnel fly-eye optical lens. The lamp outputs light after multiple light oscillations and refractions through the double-layer Fresnel fly-eye optical lens. Multiple lens beams are divided into multiple fine beams for illumination. The slight non-uniformity within each fine beam is compensated for by the superposition of the symmetrically positioned fine beams, thus ensuring effective and uniform utilization of light energy throughout the aperture. Each small lens of the compound eye lens superimposes the image of the corresponding small lens of the first compound eye lens onto the illumination surface, further ensuring uniform light distribution. The more partitions the prism compound eye lens has, the higher the uniformity of light, and the more delicate the image. It features uniform light distribution, enhanced brightness, and anti-glare properties. Furthermore, it has a simple structure, quick installation, low manufacturing cost, and provides a good visual experience by preventing glare and strong light. It also features quick installation, good heat dissipation, good structural stability, and safety and reliability.

This embodiment provides a strip light with a double-layer Fresnel fly-eye optical lens, characterized in that it includes a lamp mounting profile 1, which provides a bottom groove 11 for placing the lamp strip 2 and a placement groove 12 for a reflective light guide 3; the placement groove 12 communicates with the bottom groove 11 and is located above the bottom groove 11, covering the reflective light guide. The first layer of Fresnel fly-eye optical lens 4 is located above the mouth 31, and the second layer of Fresnel fly-eye optical lens 5 is located above the first layer of Fresnel fly-eye optical lens 4. There is a light oscillation zone space between the first layer of transparent Fresnel fly-eye optical lens and the second layer of transparent Fresnel fly-eye optical lens. The light emitted by the light strip 2 is redirected and superimposed by the reflective light guide part 3 and then oscillates in the light oscillation zone space after passing through the first layer of Fresnel fly-eye optical lens 4. The light is then refracted multiple times by the second layer of Fresnel fly-eye optical lens surface 5 to make the light uniform and anti-glare and brighten the output.

[0024] The mounting profile 1 provides a first inner slot 13 and a second inner slot 14 symmetrical to the first inner slot 13 for inserting the side of the first Fresnel fly-eye optical lens 4.

[0025] The reflective light guide 3 has a trapezoidal light cup cavity 32 that is narrow at the bottom and wide at the opening. The light cup cavity 31 has an outwardly opening and gradually widening inclined wall to collect light and output it to the first layer of Fresnel fly-eye optical lens 4.

[0026] To facilitate installation, the mounting profile 1 provides a first inner slot 13 and a second inner slot 14 symmetrical to the first inner slot 13 for inserting into the side of the first Fresnel fly-eye optical lens 4.

[0027] The mounting profile 1 is used to insert the inner hook 52 of the second Fresnel fly-eye optical lens 5 to provide a first outer slot 16 and a second outer slot 17 symmetrical to the first outer slot 16.

[0028] The outer surface of the second Fresnel fly-eye optical lens 5 forms a prism compound eye output surface 51.

[0029] The mounting profile 1 is long and narrow, with a tubular electrical contact 6 at one end. The tubular electrical contact 6 is electrically connected to the power conversion module 7. The power conversion module 7 is an AC to DC power supply. The lamp board 2 is connected to the power conversion module 7.

[0030] The mounting profile 1 can be integrally formed from metal or non-metal materials. The base plate of the reflective light guide 3 provides corresponding through holes 33 for each light-emitting body 21 on the light strip. The mounting profile 1 forms multiple heat dissipation grooves 15, which correspond to the lower position of the bottom groove 11 to facilitate the heat dissipation of the light-emitting body 21.

[0031] See Figure 3 , Figure 4 As shown, in other embodiments, the first layer of transparent Fresnel fly-eye optical lens can be a prismatic transparent optical lamp bead cover 22, and the shape of the second layer of Fresnel fly-eye optical lens above the first layer of Fresnel fly-eye optical lens can be circular, elliptical or polygonal according to the design requirements of the lamp, and is not limited to a long strip; the prismatic transparent optical lamp bead cover can also play the role of increasing light intensity, preventing glare and being aesthetically pleasing.

[0032] In summary and in conjunction with all the accompanying drawings, in this embodiment, when the strip lamp with the double-layer Fresnel fly-eye optical lens is used, the tubular electrical contact 6 is connected to the mains power, which is converted to low-voltage DC by the power conversion module 7 and then connected to the lamp strip 2. The light-emitting body 21 on the lamp strip 2 can be an LED bulb. When the light-emitting body 21 is powered on, it emits light, causing the light to be refracted and superimposed from the trapezoidal light cup cavity 32 and then redirected and superimposed to the first layer Fresnel fly-eye optical lens 4. The light oscillates in the light oscillation zone and is then refracted multiple times onto the surface 5 of the second layer Fresnel fly-eye optical lens to achieve uniform light distribution and anti-glare brightening. In this way, after multiple light oscillations and refractions by the multi-layer Fresnel fly-eye optical lenses, the output light is divided into multiple fine beams for illumination. The slight non-uniformity within each fine beam is compensated by the superposition of the fine beams in symmetrical positions, thereby effectively and uniformly utilizing the light energy within the entire aperture. Each small lens of the compound eye lens superimposes the image of the corresponding small lens of the first compound eye lens onto the illumination surface, further ensuring the uniform distribution of light. The more zones a prism compound eye lens has, the higher the uniformity of light, and the more delicate the image. It features uniform light distribution, enhanced brightness, and anti-glare properties. Furthermore, its simple structure, quick installation, low manufacturing cost, and protection against glare and strong light provide a superior visual experience. It also boasts advantages such as quick installation, good heat dissipation, structural stability, and reliability. Therefore, it exhibits superior performance in terms of technology, practicality, and economy.
