Description

A laser system for creating patterns with a wide field of view Technical Field

[0001] This invention belongs to the field of semiconductor laser application technology, and particularly relates to a laser system for pattern effects with a large field of view. Background Technology

[0002] In the field of semiconductor laser application technology, traditional laser systems using FB4 controllers and galvanometers to achieve pattern effects have many limitations. From a cost perspective, the FB4 controller and galvanometer components are expensive, increasing initial equipment purchase costs and leading to high maintenance costs due to their complex system structure, making it difficult to meet the needs of large-scale applications. Regarding pattern effects, traditional systems can only display outlines and cannot fill in the internal details, greatly limiting pattern expressiveness; furthermore, outdated spot homogenization technology results in uneven output spot brightness, affecting visual effects. When applied to large field-of-view scenarios (such as large stage projections and outdoor advertising displays), due to limitations in galvanometer scanning angle and accuracy, pattern edges are prone to stretching, distortion, and other distortions, severely reducing image quality. As the market's demands for precision, flexibility, and cost-effectiveness in laser pattern display continue to increase, innovative technologies are urgently needed to solve these problems and achieve high-performance, high-quality large field-of-view pattern output at a cost-effective price. Summary of the Invention

[0003] To address the problems existing in the prior art, this utility model provides a laser system for pattern effects with a large field of view. It has the advantages of reducing costs, high uniformity of output spot, high brightness, guaranteed pattern output quality, customizable pattern shape and color, and improved production efficiency. It solves the problems of high cost, inability to fill patterns, low spot uniformity, and obvious pattern distortion under a large field of view in the prior art.

[0004] This invention is implemented as follows: a laser system for creating a large field-of-view pattern effect includes a laser light source system, a lens system, an optical fiber connector, a collimating lens, a pattern piece, a wide-angle lens, a 200μm optical fiber, a first pressure ring, a second pressure ring, and a waterproof connector. The front panel of the laser light source system is fixed with a waterproof connector for locking the 200μm optical fiber. The rear panel of the lens system is fixed with an optical fiber connector, through which the 200μm optical fiber is connected to the lens system. The lens system contains a collimating lens, a pattern piece, and a wide-angle lens. The 200μm optical fiber exits and enters the collimating lens. The pattern piece is fixed by the first and second pressure rings. The lens system has fixing holes at its top for fixing the first and second pressure rings, and threaded holes on its front panel for fixing the wide-angle lens.

[0005] The light source module can be made into red, green, and blue light source modules respectively. The number of laser diodes in the laser light source system is matched with the power of the corresponding light source module. The light source used in this device is a laser fiber coupled light source, and the light source selection supports direct laser free space output and LED light source. The positions of the pattern piece and the wide-angle lens can be positioned by the first and second pressure rings, which makes it easy to adjust the distance between the pattern piece and the wide-angle lens, thereby adjusting the light spot to a suitable size.

[0006] As a preferred embodiment of this invention, the collimating lens, pattern sheet, wide-angle lens, first retaining ring, and second retaining ring are all optically designed to ensure that the optical axes are on the same horizontal line.

[0007] This setup ensures that the laser beam maintains a precise path during transmission, reducing issues such as beam divergence, energy loss, and pattern distortion caused by optical axis misalignment. Coaxial mounting of all optical components allows the laser, after being collimated by the collimating lens, to be fully projected onto the pattern sheet to form a clear pattern. Furthermore, the wide-angle lens uniformly and without distortion expands the field of view, thereby achieving high-brightness, high-uniformity, and large-field-of-view pattern output, improving the overall display effect and system stability.

[0008] As a preferred embodiment of this invention, the laser light source system, lens system, fiber optic connector, collimating lens, wide-angle lens, first pressure ring, second pressure ring, and waterproof connector are all made of aluminum alloy.

[0009] This design ensures durability and guarantees the flatness of the system.

[0010] As a preferred embodiment of this invention, the patterned sheet is made of high-temperature resistant sapphire material.

[0011] Through this setup, the patterned sheets also employ high-temperature stable coating technology and high-temperature sintering manufacturing process to ensure that the patterns are both colorful and heat-resistant. Furthermore, the shape and color of the patterns can be customized to achieve different pattern effects.

[0012] As a preferred embodiment of this invention, each corner connection of the laser light source system and the lens system is coated with a black silicone rubber layer.

[0013] This setting prevents light leakage and ensures optimal light output.

[0014] As a preferred embodiment of this invention, the outer surface of the 200μm optical fiber is fixedly covered with a yellow armor cladding.

[0015] This setting helps protect the optical fiber, prevents dust from entering, avoids damage caused by excessive bending, improves the efficiency of the optical fiber, and extends its service life.

[0016] As a preferred embodiment of this utility model, the collimating lens, pattern sheet, wide-angle lens, first pressure ring, and second pressure ring are all connected and fixed by mechanical structure, and are further reinforced by UV adhesive.

[0017] This setting helps reduce errors caused by structural deformation, thereby improving the quality and accuracy of pattern display.

[0018] As a preferred embodiment of this invention, the laser light source system is powered by 220V, and a 220V power interface is reserved on the rear panel of the laser light source system.

[0019] This setting makes it easy to control the on / off state of the laser output, and it is convenient to use.

[0020] As a preferred embodiment of this invention, the mounting connections of the laser light source system and the lens system are both coated with silicone rubber.

[0021] This feature provides waterproof and dustproof protection, preventing water from entering the equipment and achieving IP65 waterproof rating.

[0022] Compared with existing technologies, the beneficial effects of this utility model are as follows: it effectively ensures precise laser transmission, eliminates spot divergence and pattern distortion, improves spot uniformity and display accuracy, emits a large field of view spot, and can customize patterns of different colors and shapes according to customer needs. It can also replace wide-angle lenses with different divergence angles to change the pattern size, flexibly adjust the pattern size and field of view, and achieve high brightness, large field of view, and personalized laser pattern output at low cost, fully meeting diverse application needs.

[0028] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0029] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] Referring to Figures 1 to 4, an embodiment of this utility model provides a laser system for creating a large field of view pattern effect, including a laser light source system 1, a lens system 2, an optical fiber connector 3, a collimating lens 4, a pattern piece 5, a wide-angle lens 6, a 200μm optical fiber 7, a first retaining ring 8, a second retaining ring 9, and a waterproof connector 10. The front panel of the laser light source system 1 is fixed with the waterproof connector 10, which is used to lock the 200μm optical fiber 7. The rear panel of the lens system 2 is fixed with the optical fiber connector 3, and the 200μm optical fiber 7 is connected to the lens system 2 through the optical fiber connector 3. The collimating lens 4, the pattern piece 5, and the wide-angle lens 6 are fixed inside the lens system 2. The 200μm optical fiber 7 exits and enters the collimating lens 4. The pattern piece 5 is fixed by the first retaining ring 8 and the second retaining ring 9. The lens system 2 has a fixing hole on its upper part for fixing the first retaining ring 8 and the second retaining ring 9, and the front panel of the lens system 2 has a threaded hole for fixing the wide-angle lens 6.

[0031] The light source module can be made into red, green and blue light source modules respectively. The number of laser diodes in the laser light source system 1 is matched with the power of the corresponding light source module. The light source used in this device is a laser fiber coupled light source, and the light source can be selected to support direct laser free space output or LED light source. The positions of the pattern piece 5 and the wide-angle lens 6 can be positioned by the first pressure ring 8 and the second pressure ring 9, so as to facilitate the adjustment of the distance between the pattern piece 5 and the wide-angle lens 6, thereby adjusting the light spot to a suitable size.

[0032] Specifically, the collimating lens 4, pattern sheet 5, wide-angle lens 6, first retaining ring 8 and second retaining ring 9 are all optically designed to ensure that the optical axes are on the same horizontal line.

[0033] The above scheme ensures that the laser beam maintains a precise path during transmission, reducing issues such as beam divergence, energy loss, and pattern distortion caused by optical axis offset. The coaxial installation of each optical element allows the laser to be fully projected onto the pattern sheet 5 after being calibrated by the collimating lens 4, forming a clear pattern. The wide-angle lens 6 then uniformly and without distortion expands the field of view, thereby achieving high-brightness, high-uniformity, and large-field-of-view pattern output, improving the overall display effect and system stability.

[0034] Specifically, the laser light source system 1, lens system 2, fiber optic connector 3, collimating lens 4, wide-angle lens 6, first pressure ring 8, second pressure ring 9, and waterproof connector 10 are all made of aluminum alloy.

[0035] The above solution is robust and durable, ensuring the flatness of the system.

[0036] Specifically, the patterned piece 5 is made of high-temperature resistant sapphire material.

[0037] Using the above solution, pattern piece 5 also employs high-temperature stable coating technology and high-temperature sintering manufacturing process to ensure that the pattern is both colorful and heat-resistant, and that the shape and color of the pattern can be customized to achieve different pattern effects.

[0038] Specifically, each corner of the laser light source system 1 and the lens system 2 is coated with a black silicone rubber layer.

[0039] By adopting the above solution, light leakage is avoided and the light output effect is guaranteed.

[0040] Specifically, the outer surface of the 200μm optical fiber 7 is fixedly covered with a yellow armor cladding.

[0041] The above solution helps protect optical fibers, prevents dust from entering them, avoids damage caused by excessive bending, improves the efficiency of optical fiber use, and extends their service life.

[0042] Specifically, the collimating lens 4, patterned sheet 5, wide-angle lens 6, first retaining ring 8, and second retaining ring 9 are all connected and fixed using mechanical structures, and are further reinforced with UV adhesive.

[0043] The above approach helps to reduce errors caused by structural deformation and improve the quality and accuracy of pattern display.

[0044] Specifically, the laser light source system 1 is powered by 220V, and a 220V power interface is reserved on the rear panel of the laser light source system 1.

[0045] The above scheme facilitates the control of laser output switching and is easy to use.

[0046] Specifically, the mounting joints of the laser light source system 1 and the lens system 2 are coated with silicone rubber.

[0047] The above solution provides waterproof and dustproof protection, preventing water from entering the equipment and achieving IP65 waterproof rating.

[0048] The working principle of this utility model:

[0049] In use, the lens system 2 is assembled, including the fiber optic connector 3, collimating lens 4, patterned plate 5, wide-angle lens 6, and retaining rings. First, the 200μm fiber 7 is connected to the fiber optic connector 3, and then connected to the collimating lens 4 through the fiber optic connector 3. The collimating lens 4 and patterned plate 5 are fixed inside the lens system 2. The patterned plate 5 is fixed between the first retaining ring 8 and the second retaining ring 9. There are fixing holes on the top of the lens system 2 to fix the positions of the first retaining ring 8 and the second retaining ring 9. The front panel of the lens system 2 has threaded holes, and the wide-angle lens 6 is fixed by the threads. The beam emitted from the collimating lens 4 hits the patterned plate 5, and then the wide-angle lens 6 expands the beam for imaging. The wide-angle lens 6 with different divergence angles can be replaced according to different field of view requirements to achieve different field of view pattern effects, thus achieving the desired light spot.

[0050] The laser source system 1 outputs laser light through a 200μm optical fiber 7. The first retaining ring 8 and the second retaining ring 9 can position the pattern piece 5 and the wide-angle lens 6, facilitating the adjustment of the distance between the pattern piece 5 and the wide-angle lens 6, thereby adjusting the light spot to a suitable size. The lens system 2 ultimately outputs a light spot with high uniformity, high brightness, and a large field of view. The pattern shape can be customized, and different colors and shapes can be customized according to customer needs. The size of the wide-angle lens 6 can also be customized with different divergence angles. When installing the lens system 2, attention should be paid to the angle of light emission to ensure that the light output height of the optical fiber and collimating lens 4 is on the same horizontal line as the pattern piece 5. After all assembly is completed, the light output is tested and adjusted, and the positions of the first retaining ring 8 and the second retaining ring 9 are fixed. The installation is then complete.
