Description

Technical Field

[0001] This utility model relates to the field of lens technology, specifically to an integrated lens system for PAR lamps. Background Technology

[0002] The integrated lens of a PAR lamp refers to an optical component that integrates the lens and the light source to achieve the integration of high and low beams. The switching between high and low beams is achieved through an internal light shield or reflective structure, and only one light source is needed to complete the two lighting modes.

[0003] The existing problems with lenses include low light efficiency, uneven color mixing, unstable structure, poor heat resistance, and inconvenient beam angle adjustment. The reason for this problem is that traditional PAR lamps use a separate lamp cup and lens design, which has low optical path efficiency, poor light spot uniformity, and is prone to central bright spots or blurred edges. In addition, the existing optical system does not support the mixing of multi-color light sources such as RGBW, the mixing distance is long, the color transition is unnatural, and it affects the stage lighting effect. At the same time, PAR lamps generate a lot of heat during long-term operation, and ordinary lens materials have poor heat resistance and are prone to deformation, which leads to a decline in optical performance. The separate structure is complicated to assemble, has poor shock resistance, and is prone to misalignment during transportation or use, affecting the alignment of the optical axis and the consistency of light output. The existing system has a fixed beam angle, which is difficult to flexibly adapt to the needs of different application scenarios. Therefore, we propose an integrated lens system for PAR lamps.

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.

[0015] This application provides an integrated lens system for PAR lamps, which solves the existing problems of low lens luminous efficiency, uneven color mixing, unstable structure, poor heat resistance, and inconvenient beam angle adjustment.

[0016] 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.

[0017] According to the appendix Figure 1 - Figure 5 As shown, the lamp includes a lamp cup body 1, and a lens mechanism is provided on the outside of the lamp cup body 1. The lens mechanism includes a lens body 2, which is located inside the lamp cup body 1. The lens body 2 improves the light source mixing effect through a curved surface design. A heat sink body 201 is located on the outside of the lens body 2, and the heat sink body 201 increases the heat dissipation effect of the lens body 2.

[0018] The lamp cup body 1 is provided with an outer frame 203, which is used to support the entire lamp cup body 1. A connector 202 is installed on the back of the lens body 2, which is used to connect the lens body 2 to other structures. The heat dissipation body 201 is provided on the back of the lens body 2.

[0019] By adopting an integrated design of the lamp cup body 1 and the lens body 2, the optical path structure is simplified, improving light efficiency and beam uniformity. The lens body 2 features an optimized curved surface design, supporting rapid mixing of multi-color light sources such as RGBW, shortening the mixing distance, and improving color consistency. The lamp cup body 1 has a compact structure between its external and internal parts, good shock resistance, and is easy to assemble, making it suitable for stage lighting fixtures used at high frequencies. The lamp cup body 1, lens body 2, heat sink body 201, connector 202, and frame are all made of high heat-resistant optical materials. Combined with the heat dissipation structure design, they effectively resist thermal deformation. The modular design supports multiple beam angle options, allowing users to quickly replace them to adapt to different lighting needs.

[0020] To address the requirements of PAR lamps for luminous efficacy, color mixing, heat dissipation, and structural stability, an integrated optical system combining a lamp cup body 1 and a lens body 2 is designed to achieve high luminous efficacy, high uniformity, and high reliability lighting effects. The optical system structure adopts an integrated design of the lamp cup body 1 and the lens body 2, reducing optical path interface losses and improving luminous efficacy. The curved surface of the lens body 2 is optimized by optical software to achieve a light spot uniformity of more than 90% within the working distance. It has a built-in mixing area to promote uniform mixing of multi-color light sources. The material used is high-temperature resistant PMMA, which can withstand the high temperatures generated by LEDs during long-term operation. A heat sink body 201 is set on the back of the lens body 2 to enhance heat dissipation capacity. The modular design can provide multiple beam angle modules such as 15°, 25°, and 50°, supporting quick replacement. The module interface is standardized to ensure the optical axis alignment accuracy after replacement. Taking RGBW color mixing as an example, the four-color LED light enters the integrated lens system, undergoes preliminary collimation and mixing through the built-in reflector cup and refractive surface, and finally forms a uniform and well-mixed light spot from the light-emitting surface.

[0021] In summary, compared with existing technologies, it has the following beneficial effects: By adopting an integrated design of the lamp cup body 1 and the lens body 2, the optical path structure is simplified, improving light efficiency and beam uniformity. The lens body 2 features an optimized curved surface design, supporting rapid mixing of multi-color light sources such as RGBW, shortening the mixing distance, and improving color consistency. The lamp cup body 1 has a compact external and internal structure, good shock resistance, and is easy to assemble, making it suitable for stage lighting fixtures used at high frequencies. The lamp cup body 1, lens body 2, heat sink body 201, connector 202, and frame are all made of high heat-resistant optical materials. Combined with the heat dissipation structure design, it effectively resists thermal deformation. The modular design supports multiple beam angle options, allowing users to quickly replace them to adapt to different lighting needs. Through the integrated design of the lamp cup body 1 and the lens body 2, as well as the curved surface design of the lens body 2, problems such as low light efficiency, uneven color mixing, structural instability, poor heat resistance, and inconvenient beam angle adjustment are solved, improving the optical performance, reliability, and applicability of the lighting fixture.
