Description

Technical Field

[0001] This utility model relates to the field of lens technology, specifically to an optical lens system for the LM120S mini plastic moving head color dyeing lamp. Background Technology

[0002] Optical lenses alter the path of light through refraction, thereby adjusting the shape of the light spot and the distribution of brightness. They are commonly used in scenes that require illumination.

[0003] Existing optical lens systems suffer from problems such as low light efficiency, uneven color mixing, poor optical stability, insufficient heat resistance, and limited beam angle adjustment, which raise the issue of improving the optical performance and reliability of luminaires. The reason for this problem is that traditional lenses have low light efficiency and poor beam uniformity, which can easily lead to excessive brightness in the center or insufficient brightness at the edges. At the same time, existing lens systems do not support multi-color mixing such as RGBW well, have long mixing distances, and unsatisfactory color uniformity. When moving head lights are in operation, they move frequently, and ordinary lens fixing methods are prone to displacement or loosening, affecting optical consistency. Plastic housing lamps have limited heat dissipation capacity, and lenses are prone to deformation when heated for a long time, affecting optical performance. Existing lens systems cannot simultaneously meet the dual requirements of variable beam angle and high beam quality. Therefore, we propose an optical lens system for the LM120Smini plastic moving head color-changing light. Utility Model Content

[0006] Preferably, the lens body has a fixing groove on its exterior, which is used to connect the lens body to other structures.

[0007] The beneficial effects of this utility model are: The technical solution of this utility model significantly improves the light efficiency and beam uniformity by using a multi-free-form surface composite optical design for the hybrid lens. It supports efficient mixing of multi-color light sources such as RGBW, shortens the mixing distance, and improves color consistency. The external structure of the lens body is compatible with plastic shells, providing good shock resistance and motion stability.

Through the multi-free-form surface composite optical design of the hybrid lens and the micro-fins of the heat dissipation fins, it solves problems such as low light efficiency, uneven color mixing, poor optical stability, insufficient heat resistance, and limited beam angle adjustment, thereby improving the optical performance and reliability of the lamp.

[0011] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0012] This application provides an optical lens system for the LM120S mini plastic moving head color-changing light, which solves the problems of low light efficiency, uneven color mixing, poor optical stability, insufficient heat resistance and limited beam angle adjustment in existing optical lens systems, thereby improving the optical performance and reliability of the light fixture.

[0013] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0014] According to the appendix Figure 1 - Figure 5 As shown, the lens body 1 is provided with a light transmission mechanism on the outside of the lens body 1. The light transmission mechanism includes a hybrid lens 2, which is provided on the outside of the lens body 1. The hybrid lens 2 adopts an integrated lens structure design combining a collimating lens and a hybrid lens, which is used for preliminary convergence of light to optimize the light spot and color mixing effect. The heat dissipation fins 202 are provided on the front of the hybrid lens 2. The heat dissipation fins 202 increase the heat dissipation area through micro fins.

[0015] The lens body 1 has a fixing groove 201 on its exterior, which is used to connect the lens body 1 to other structures.

[0016] By employing a multi-freeform surface composite optical design, the hybrid lens 2 significantly improves light efficiency and beam uniformity, supports efficient mixing of multi-color light sources such as RGBW, shortens the mixing distance, and improves color consistency. The external structure of the lens body 1 is compatible with a plastic shell, providing good shock resistance and motion stability. The structure uses high-temperature resistant optical materials to enhance the lens's resistance to deformation under limited heat dissipation conditions. The modular design supports quick replacement of different optical modules, enabling multiple beam angle outputs. Through the multi-freeform surface composite optical design of the hybrid lens 2 and the micro-fins of the heat dissipation fins 202, problems such as low light efficiency, uneven color mixing, poor optical stability, insufficient heat resistance, and limited beam angle adjustment are solved, thereby improving the optical performance and reliability of the luminaire.

[0017] The hybrid lens 2 is designed by combining a collimating lens and a hybrid lens 2. The collimating lens initially converges the light emitted by the LED, while the hybrid lens 2 further optimizes the light spot and color mixing effect. The lens surface is optimized by optical software to achieve a light spot uniformity of more than 90% within the working distance. The material selected is high-temperature resistant PMMA material, which can withstand the heat generated by the LED light source during long-term operation. The front of the lens is designed with heat dissipation fins 202. The heat dissipation fins 202 are micro fins to increase the heat dissipation area and delay material aging. The modular design can provide lens modules with various beam angles such as 15°, 25°, and 40°, which users can quickly replace as needed. At the same time, the module interface design is uniform to ensure the optical axis alignment accuracy after replacement. Taking RGBW color mixing as an example, the four-color LED light rays are initially collimated by the collimating lens, and the light enters the area of ​​the hybrid lens 2 for spatial color mixing. Finally, it is led out by the light-emitting surface to form a uniformly mixed color light spot.

[0018] In summary, compared with existing technologies, it has the following beneficial effects: By employing a multi-freeform surface composite optical design, the hybrid lens 2 significantly improves light efficiency and beam uniformity, supports efficient mixing of multi-color light sources such as RGBW, shortens the mixing distance, and improves color consistency. The external structure of the lens body 1 is compatible with a plastic shell, providing good shock resistance and motion stability. The structure uses high-temperature resistant optical materials to enhance the lens's resistance to deformation under limited heat dissipation conditions. The modular design supports quick replacement of different optical modules, enabling multiple beam angle outputs. Through the multi-freeform surface composite optical design of the hybrid lens 2 and the micro-fins of the heat dissipation fins 202, problems such as low light efficiency, uneven color mixing, poor optical stability, insufficient heat resistance, and limited beam angle adjustment are solved, thereby improving the optical performance and reliability of the luminaire.
