Description

Technical Field

[0001] This utility model relates to the field of light source technology, and in particular to a multi-color combined light source. Background Technology

[0002] In current light source applications, single-color light sources are no longer sufficient to meet diverse needs, and multi-color combination light sources are gaining increasing use due to their ability to achieve rich color variations. However, existing multi-color combination light sources have several shortcomings in practical use:

[0003] 1) Most multi-color combination light sources have poor light focusing effect. It is difficult for different colors of light to be accurately focused into a uniform bright spot, resulting in uneven color distribution and scattered light spot in the output light, which affects the use effect.

[0004] 2) Although some multi-color combination light sources can achieve multi-color mixing, they have limitations in color purity, color rendering, and brightness adjustment. For example, when only red, green, and blue (RGB) light sources are used for mixing, insufficient color purity and poor color rendering in some color areas are likely to occur. Furthermore, it is difficult to flexibly adjust the use mode of single color or multi-color combination according to actual needs.

[0005] 3) The existing multi-color combined light source has an unreasonable structural design, poor connection stability between components, and is inconvenient to assemble and debug, which is not conducive to mass production and practical application.

[0006] In view of the problems existing in the above-mentioned technologies, there is an urgent need for a multi-color combination light source that can achieve high-purity color output, improve color rendering and brightness, and has a stable structure and flexible use. Summary of the Invention

[0007] The purpose of this invention is to provide a multi-color combination light source that, through optimized overall structural design and in conjunction with a specific light source combination and focusing module, achieves high-purity color output, improves color rendering and brightness, while also having flexible color adjustment and usage modes, and is structurally stable, easy to assemble and use, thereby solving the aforementioned technical problems.

[0008] To achieve the above technical solution, the technical solution of this utility model is as follows: A multi-color combined light source, comprising a light source for generating light of different colors, the multi-color combined light source further comprising:

[0009] A focusing module is adjustable and positioned on the light path transmitted by the light source, used to combine and focus the light output from the light source.

[0010] Wherein: the focusing module is an aspherical lens, and the various lights transmitted by the light source are converged into a bright spot for output through the aspherical lens.

[0011] Furthermore, the focusing module also includes a peripheral ring and a retaining ring; the aspherical lens is coaxially disposed inside the peripheral ring and fixed by the retaining ring.

[0012] Furthermore, the circumference is a hollow ring; one end of the circumference is provided with an internal thread, and the other end is provided with a through locking hole along the radial direction; the circumference is provided with an inwardly recessed annular groove along the axis.

[0013] Furthermore, a hollow sleeve is screwed onto the internal thread.

[0014] Furthermore, the area of ​​the light source is much smaller than the area of ​​the incident surface of the aspherical lens.

[0015] Furthermore, the light source includes a four-color light source circuit board; the four-color light source circuit board is fixedly connected to the base by fasteners; the four-color light source circuit board is electrically connected to a four-way light source line.

[0016] Furthermore, the four colors on the four-color light source circuit board are red, green, blue and white LED beads; one end of the base extends outward symmetrically with a circuit board mounting part; a four-color light source line is arranged between adjacent circuit board mounting parts; the other end of the base is provided with a second annular groove arrayed along the axis.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1) Through the overall structural design, this utility model, combined with the mixed imaging of four LED light sources (red, green, blue, and white), uses an aspherical lens to accurately converge the four colors of light into a uniform bright spot, avoiding light dispersion or uneven color, significantly improving color purity, and ensuring that the output light is full and accurate in color.

[0019] 2) This utility model uses a one-to-four light source line to independently control four types of LED beads, which can flexibly adjust the proportion of red, green, blue and white light according to actual needs. It can not only achieve rich color mixing effects, but also accurately adjust the brightness of the overall light source to meet the diverse needs for color and brightness in different scenarios.

[0020] 3) By adding white LED beads, this utility model effectively makes up for the shortcomings in color rendering and brightness when mixing traditional RGB three-color light sources. On the one hand, it makes the mixed color closer to the natural color, improves the color rendering effect, and is suitable for scenarios with high requirements for color reproduction. On the other hand, it also significantly improves the overall brightness of the light source and expands the application range of the light source.

[0021] 4) This utility model can be used in single color or multi-color combination according to actual needs. For example, in a scenario where only a single color of light is needed, the corresponding color of LED can be turned on individually; in a scenario where multiple colors of light are needed, multiple colors of LED can be turned on and their proportions can be adjusted, making it extremely flexible to use.

[0022] 5) The coordination between the peripheral ring, pressure ring and aspherical lens in the focusing module of this utility model, as well as the fixed connection between the four-color light source circuit board and the base in the light source, ensure the stability of the overall structure; at the same time, the connection between the components is simple and reliable, which facilitates assembly, disassembly and maintenance, and is conducive to mass production and practical application.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Please see the appendix Figures 1 to 2 As shown: A multi-color combined light source includes a light source 1 for generating light of different colors, and the multi-color combined light source further includes:

[0029] The focusing module 2 is adjustablely positioned on the light path transmitted by the light source 1, and is used to combine and focus the light output from the light source 1 to produce concentrated light rays.

[0030] Wherein: the focusing module 2 is an aspherical lens 21, and the various lights transmitted by the light source 1 are converged into a bright spot output through the aspherical lens 21.

[0031] Based on the above embodiment, the focusing module 2 further includes a peripheral ring 22 and a retaining ring 23; the aspherical lens 21 is coaxially disposed inside the peripheral ring 22 and fixed by the retaining ring 23. The cooperation between the peripheral ring 22 and the retaining ring 23 ensures the positional stability of the aspherical lens 21 during use, preventing lens displacement due to vibration or other factors, thus avoiding impact on the light focusing effect. It also facilitates the installation, disassembly, and replacement of the aspherical lens 21, improving the module's maintenance convenience.

[0032] Based on the above embodiments, the circumference 22 is a hollow ring; one end of the circumference 22 is provided with an internal thread 221, and the other end is provided with a through locking hole 222 along the radial direction; the circumference 22 is provided with an inwardly recessed annular groove 223 along the axis. The hollow annular structure of the periphery 22 provides a channel for light transmission, ensuring that the light output from the light source 1 can smoothly enter the aspherical lens 21. The internal thread 221 facilitates the connection of the periphery 22 with other components, enabling the adjustment and fixation of the focusing module 2 in the overall light source structure. The locking hole 222 can be used with locking components such as set screws. When the periphery 22 is connected with other components, the locking component passes through the locking hole 222 and presses against the corresponding component, further enhancing the stability of the connection and preventing the periphery 22 from rotating or shifting during use. The annular groove 223 can be used to accommodate sealing or positioning components. On the one hand, it can improve the sealing between the periphery 22 and adjacent components, preventing dust, moisture and other impurities from entering the interior and affecting the performance of the light source. On the other hand, it can also assist in the coaxial positioning of the aspherical lens 21, ensuring the accuracy of lens installation.

[0033] Based on the above embodiment, a hollow sleeve 3 is screwed onto the internal thread 221. The sleeve 3 extends the light transmission path, facilitating adjustment of the distance between the light source 1 and the aspherical lens 21 according to actual needs, thereby optimizing the light focusing effect and allowing adjustment of the spot size and focusing accuracy. Furthermore, the hollow sleeve 3 provides some protection for the light, reducing interference from the external environment, and also provides installation space for the light source 1, facilitating the overall structure layout and assembly.

[0034] Based on the above embodiments, the area of ​​the light source 1 is much smaller than the area of ​​the light incident surface of the aspherical lens 21. This design ensures that all the light emitted from the light source 1 can be incident on the aspherical lens 21 as much as possible, avoiding light loss due to insufficient incident surface, improving light utilization, and also facilitating the aspherical lens 21 to fully converge the light, ensuring that multiple colors of light can be accurately converged into a uniform and bright spot, improving color purity and the quality of the output light.

[0035] Based on the above embodiments, the light source 1 includes a four-color light source circuit board 11; the four-color light source circuit board 11 is fixedly connected to the base 12 by fasteners; the four-color light source circuit board 11 is electrically connected to a four-color light source line 13. As the core component of the light source 1, the four-color light source circuit board 11 is used to install and fix the light-emitting elements. The fixed connection between the four-color light source circuit board 11 and the base 12 by fasteners ensures the stability of the four-color light source circuit board 11 during use, preventing the circuit board from shifting or being damaged due to vibration or other factors. The four-color light source line 13 enables independent power supply and control of the four colors of light on the four-color light source circuit board 11, laying the foundation for subsequent independent adjustment of the four colors of light, and facilitating flexible adjustment of the brightness and proportion of each color of light according to actual needs.

[0036] Based on the above embodiments, the four colors on the four-color light source circuit board 11 are four types of LED beads: red, green, blue, and white; one end of the base 12 extends outward symmetrically and is provided with a circuit board mounting part; a four-color light source line 13 is arranged between adjacent circuit board mounting parts; the other end of the base 12 is provided with a second annular groove arrayed along the axis. Red, green, and blue (RGB) LEDs are the foundation for color mixing. By adjusting the brightness ratio of these three types, multiple colors can be mixed and output. The addition of white LEDs effectively supplements the shortcomings of RGB mixing. On the one hand, it improves the overall color rendering of the light source, making the mixed colors closer to natural colors and avoiding color deviation or distortion. On the other hand, it significantly increases the overall brightness of the light source, meeting the needs of high-brightness scenarios. The symmetrically arranged circuit board mounting section provides a stable support structure for the installation of the four-color light source circuit board 11, ensuring the flatness and accuracy of the circuit board installation. At the same time, the space between adjacent circuit board mounting sections facilitates the arrangement of the four-light source lines 13, preventing the light source lines from being squeezed or damaged due to messy arrangement, and ensuring the stability of the circuit connection. The second annular groove at the other end of the base 12 can be used to cooperate with other components such as the sleeve 3 or external mounting structures. By setting a sealing or positioning component in the second annular groove, the sealing and stability of the connection between the base 12 and other components can be improved. It also facilitates the installation and fixation of the overall light source in different devices or scenarios, enhancing the versatility of the light source.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art should be able to make equivalent embodiments by making some changes or modifications to the above-disclosed technical content without departing from the scope of the present invention.
