Description
Technical Field
[0001] This utility model relates to the field of stage lighting, and more specifically, to an optical module and a light-emitting device. Background Technology
[0002] In the field of optical lighting, the performance of light source modules needs to be adapted to different illumination scenarios to meet varying requirements. For example, in low-beam scenarios, i.e., large-area uniform illumination at close range, high uniformity of light distribution is required to avoid visual discomfort or manufacturing defects caused by localized over-brightness or under-brightness. In high-beam scenarios, i.e., focused illumination at a distance, high light density is more relied upon to achieve sufficient illumination intensity, and the requirement for uniformity is relatively lower. To solve the problem of low-beam uniformity, existing technologies generally require homogenization of the original light field emitted by the light source to make the light distribution more uniform when illuminating a large area at low beams, significantly improving the lighting effect in low-beam scenarios. This solution has become the mainstream technical approach for improving low-beam uniformity.
[0003] However, existing technologies relying on optical integrating components have significant limitations. On the one hand, homogenization is achieved through multiple superpositions of the light field, essentially dispersing the original light energy over a larger area to reduce local intensity differences. This incurs a "homogenization cost," resulting in reduced light energy, and the deficiencies caused by this homogenization become more pronounced when switching to high-beam scenarios. When the high-beam beam is homogenized, the light energy that originally needed to be highly concentrated is dispersed, ultimately resulting in a significant reduction in light density during high-beam illumination, failing to meet the lighting requirements for long distances or high energy demands, such as deep illumination and long-distance projection. On the other hand, the high-beam beam itself has a naturally high concentration and is far less sensitive to homogenization than in near-beam scenarios. Therefore, the "forced homogenization" of the beam not only fails to improve performance in high-beam mode but also reduces overall efficiency due to light energy loss. Existing homogenization-dependent solutions make it difficult for the light source module to simultaneously meet the dual requirements of near-beam homogenization and high light density in high-beam scenarios. Utility Model Content
[0004] The present invention aims to overcome at least one of the defects of the prior art and provide an optical module to solve the problem that the overall light efficiency of the existing light source module is reduced after light homogenization processing, and the high beam illumination effect cannot be achieved.
[0005] The technical solution adopted in this utility model is an optical module, including a housing and a component disposed within the housing: A light source assembly, comprising multiple light sources arranged in an array; Optical integrating components; Concentrating light components; The light beam generated by the light source component passes sequentially through the optical integrating component and the focusing component; The optical integrating component includes an optical integrating region and a beam adjustment region. When the light beam passes through the optical integrating component, part of it passes through the optical integrating region and the other part passes through the beam adjustment region. The luminous flux passing through the beam adjustment region is greater than the luminous flux passing through the optical integration region.
[0006] The light source component is used to emit a light beam, the optical integrating component is used to homogenize the light, and the focusing component is used to focus the light beam. Among them, the optical integrating region of the optical integrating component is used to homogenize the light, and the beam adjustment region is used to form a second functional region different from the optical integrating region. This allows the same light beam to undergo different processing when passing through the optical integrating region, with only a portion undergoing optical integration. The limitation of light flux makes the portion passing through the beam adjustment region more efficient, eliminating the problems caused by the traditional optical integrating component's forced homogenization of the entire beam.
[0007] To save costs, the beam adjustment area is located in the middle of the optical integrating assembly, and the optical integrating area surrounds the beam adjustment area; The shape of the beam adjustment area matches the shape of the optical integrating component, and forms an optical channel connecting the light source component and the focusing component in the optical integrating component.
[0008] Matching the shape of the beam adjustment area with the shape of the optical integrating component means that the beam adjustment area and the optical integrating component can be set on the same optical element, saving manufacturing costs.
[0009] In order to simultaneously meet the requirements for uniformity of near beam and optical density of far beam, the optical integrating component includes a substrate and an opening penetrating the substrate; The substrate includes: a functional surface and a base plane; The functional surface is provided with a first compound eye array; The substrate forms the optical integration region; The opening forms the beam adjustment area.
[0010] The first compound eye array on the substrate is used to homogenize the light; the opening allows the beam to pass through unobstructed, preserving the characteristics of high beam.
[0011] To improve the stability of the structure, a second optical element is also provided on the optical channel; The second optical element is a compound eye lens, which includes a second compound eye array; The focal length of the microlens unit in the second compound eye array is greater than the focal length of the microlens unit in the first compound eye array.
[0012] The combination of the second optical element and the first optical element makes the substrate more stable and less prone to breakage due to uneven stress, thus improving the service life of the optical components.
[0013] To improve the stability of the structure, a third optical element is also provided on the optical channel; The third optical element is a lens, and / or a frosted lens, and / or a diffuser lens.
[0014] The third optical element is used to transmit light through the beam adjustment zone.
[0015] The combination of the third optical element and the first optical element makes the substrate more stable and less prone to breakage due to uneven stress, thus improving the service life of the optical components.
[0016] To ensure the stability of the integrating element structure, the optical integrating assembly includes: a support, and at least two integrating elements spaced apart on the support; The two adjacent integrating elements are arranged opposite each other.
[0017] The bracket is used to fix the integrating element and ensure the stability of the integrating element structure.
[0018] To improve the uniformity of light, at least one integrating element has a through-hole beam adjustment region; At least one beam adjustment zone of the integrating element located between the opening and the focusing assembly is a compound eye lens.
[0019] Compound eye lenses are used to homogenize light.
[0020] In order to collimate the light, the light source assembly also includes a light-emitting circuit board, a first collimation component, and a second collimation component; The light source is disposed on the light-emitting circuit board; The second collimation assembly includes: a main body and a second collimation lens unit disposed on the main body; The first collimation component is disposed between the second collimation component and the light-emitting circuit board, and includes a plurality of first collimation lens units spaced apart. The number and position of the first collimating lens unit and the second collimating lens unit are matched one-to-one with the light source.
[0021] The first and second collimators are used to collimate the light rays.
[0022] To achieve optical zoom, a light-emitting device includes: a controller, a fixed lens assembly, a zoom lens assembly, and a focusing lens assembly, wherein the zoom lens assembly is movably disposed between the fixed lens assembly and the focusing lens assembly. It also includes the aforementioned optical module for a lamp; the optical module is connected to the controller, and the optical module emits a light beam that passes sequentially through a focusing lens assembly, a zoom lens assembly, and a fixed lens assembly.
[0023] Fixed lens assembly is used to provide a stable focal length and field of view; zoom lens assembly is used to change the focal length and field of view to achieve optical zoom; focusing lens assembly is used for focusing and imaging.
[0024] To reduce losses, the light source assembly includes a first light-emitting area located in the center and a second light-emitting area surrounding the first light-emitting area; When the distance between the zoom lens assembly and the fixed lens assembly reaches its minimum value, the second light-emitting area is turned off by the controller.
[0025] Both the first and second light-emitting areas are controlled by the controller to selectively emit light, which can reduce losses.
[0026] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting an optical integration region and a beam adjustment region on the optical integrating component, the optical integration region is used to homogenize the light. The design of the beam adjustment region enables targeted local homogenization of the beam after optical integration, which satisfies the homogenization requirements of the near beam and preserves the optimal beam path in the high beam state. This allows the beam in the high beam state to reduce or avoid optical integration, thereby improving the adaptability to both near and high beams. The beam adjustment region is used to enhance the power of the high beam.
[0027] Furthermore, by setting a first compound eye array in the optical integrating region and a second compound eye array or a third optical element in the beam adjustment region, a uniform effect for near beam and an increase in power for far beam are ensured; the two oppositely arranged integrating elements are fixed by a bracket to ensure a uniform light effect; finally, the converged light is zoomed through a light-emitting device to optimize the effect of near and far beams.

Detailed Implementation
[0044] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.
[0045] Example 1 like Figure 1-3 As shown, this embodiment is an optical module, serving as a stage light, including a housing 100, and a module disposed within the housing 100: The light source assembly 200 includes multiple light sources 210 arranged in an array; Optical Integrator 300; Concentrator module 400; The light beam generated by the light source assembly 200 passes sequentially through the optical integrating assembly 300 and the focusing assembly 400; The optical integrating component 300 includes an optical integrating region and a beam adjustment region. When the light beam passes through the optical integrating component 300, part of it passes through the optical integrating region and the other part passes through the beam adjustment region. The luminous flux passing through the beam adjustment region is greater than the luminous flux passing through the optical integration region.
[0046] By arraying the light source 210, the light intensity is enhanced, and the uniformity of light is improved to a certain extent. An optical integration area is set on the optical integration component 300 to homogenize the beam passing through the area, ensuring the uniformity of near light. A beam adjustment area is set to ensure the overall luminous flux, retain the characteristics of far light, and improve the efficiency of the light source component 200.
[0047] The beam adjustment area is located in the middle of the optical integrating component 300, and the optical integrating area surrounds the beam adjustment area; The shape of the beam adjustment area matches the shape of the optical integrating component 300, and an optical channel connecting the light source component 200 and the focusing component 400 is formed in the optical integrating component 300.
[0048] By setting the beam adjustment area in the middle of the optical integrating component 300, the concentration and utilization of the beam are ensured.
[0049] like Figure 8 and 10 As shown in Figure 11, the optical integrating component 300 includes a substrate 310 and an opening 320 penetrating the substrate 310; The substrate 310 includes: a functional surface 311 and a base plane 312; The functional surface 311 is provided with a first compound eye array 3111; The substrate 310 forms the optical integration region; The opening 320 forms the beam adjustment area.
[0050] By setting a first compound eye array 3111 on the functional surface 311 of the substrate 310, an optical integration region is formed to achieve light homogenization operation for near light; a beam adjustment region is formed in the opening 320, and the beam passes directly through the opening and converges at a distance to ensure the concentration of light in the far light stage; and the combination of the compound eye array and the opening 320 maximizes the light flux.
[0051] like Figure 8 and 11 As shown in Figure 12, a second optical element 321 is also provided on the optical channel; The second optical element 321 is a compound eye lens, which includes a second compound eye array; The focal length of the microlens unit of the second compound eye array is greater than the focal length of the microlens unit of the first compound eye array 3111.
[0052] By setting a second compound eye array on the optical integrating component 300 with a focal length greater than that of the microlens unit of the first compound eye array 3111, the first compound eye array 3111 can homogenize the light at closer distances, and the second compound eye array can homogenize the light at farther distances. This achieves homogenization of light beams at different distances to a certain extent. Furthermore, the light beam passing through the second compound eye array will be farther than the light beam passing through the first compound eye array 3111. Within a certain distance range, this ensures both the uniformity of light and the preservation of light characteristics.
[0053] like Figure 8 and 13 As shown, a third optical element 322 is also provided on the optical channel; The third optical element 322 is a lens, and / or a frosted lens, and / or a diffuser lens.
[0054] By setting a lens, or a frosted lens, or a diffuser lens as a third optical component at the opening 320 of the substrate 310, the light transmittance of the beam adjustment area is guaranteed while ensuring the stability of the structural substrate 310.
[0055] like Figure 9 As shown, the optical integrating assembly 300 includes: a support 330, and at least two integrating elements spaced apart on the support 330; The two adjacent integrating elements are arranged opposite each other.
[0056] The integrating element of the optical integrating assembly 300 is fixed by the bracket 330 to ensure the structural stability of the integrating element. At the same time, under the action of the bracket 330, the two adjacent integrating elements are arranged opposite each other, which improves the uniformity of light.
[0057] Used in the structure of optical integrating component 300 to improve uniformity.
[0058] like Figure 2 and 8 As shown, the beam adjustment area of at least one integrating element is a through opening 320; At least one beam adjustment area of the integrating element located between the opening 320 and the focusing assembly 400 is a compound eye lens.
[0059] The characteristics of high beam are preserved by setting the opening 320; the compound eye lens is used to homogenize the light, and together with the first compound eye lens, it improves the uniformity of the light.
[0060] like Figure 4 , 6 As shown in Figures 7 and 8, the light source assembly 200 further includes a light-emitting circuit board 220, a first collimation assembly 230, and a second collimation assembly 240. The light source 210 is disposed on the light-emitting circuit board 220; The second collimation assembly 240 includes: a main body 242 and a second collimation lens unit 241 disposed on the main body 242; The first collimation component 230 is disposed between the second collimation component 240 and the light-emitting circuit board 220, and includes a plurality of first collimation lens units 231 arranged at intervals; The number and position of the first collimating lens unit 231 and the second collimating lens unit 241 are matched one-to-one with the light source 210.
[0061] The first collimator 230 collimates the emitted light, making the light with an emission angle become parallel light or making the light rays tend to be parallel; the second collimator 240 is paired with the first collimator 230 to collimate the light rays transmitted through the first collimator 230 again, making the light rays become parallel light.
[0062] like Figure 15 As shown, a light-emitting device 500 includes: a controller, a fixed lens assembly 510, a zoom lens assembly 520, and a focusing lens assembly 530, wherein the zoom lens assembly 520 is movably disposed between the fixed lens assembly 510 and the focusing lens assembly 530. It also includes the aforementioned optical module for a lamp; the optical module is connected to the controller, and the optical module emits a light beam that passes sequentially through the focusing lens assembly 530, the zoom lens assembly 520, and the fixed lens assembly 510.
[0063] The light-emitting device 500 is composed of a fixed lens assembly 510, a zoom lens assembly 520, and a focusing lens assembly 530, which optimizes the effects of both near and far light.
[0064] like Figure 5 and 15 As shown, the light source assembly 200 includes a first light-emitting area 211 located in the center, and a second light-emitting area 212 disposed around the first light-emitting area 211; When the distance between the zoom lens assembly 520 and the fixed lens assembly 510 reaches its minimum value, the second light-emitting area 212 is turned off by the controller.
[0065] By setting a first light-emitting area 211 and a second light-emitting area 212 on the light source assembly 200, the light sources 210 located in different areas are separated, so that they can meet different needs, while also ensuring optical efficiency and reducing losses.
[0066] Example 2 like Figure 1-2 As shown, an optical module, serving as a stage light, includes a housing 100, a light source assembly 200, an optical integrating assembly 300, and a focusing assembly 400. The light source assembly 200, the optical integrating assembly 300, and the focusing assembly 400 are disposed within the housing 100. The light beam emitted by the light source 210 module passes sequentially through the optical integrating assembly 300 and the focusing assembly 400. The optical integrating assembly 300 forms an optical channel connecting the light source assembly 200 and the focusing assembly 400.
[0067] like Figure 3-5As shown, the light source assembly 200 includes a light source 210, a light-emitting circuit board 220, a first collimator 230, and a second collimator 240. The light source 210 is arranged in an array on the light-emitting circuit board 220. The light source 210 can be selected from LED beads 213. The light source 210 can be divided into multiple light-emitting areas. Taking two light-emitting areas as an example, it is divided into a first light-emitting area 211 and a second light-emitting area 212. The first light-emitting area 211 is located in the middle, and the second light-emitting area 212 surrounds the first light-emitting area 211. When low beam is needed, the controller controls the LED beads 213 in the first light-emitting area 211 and the second light-emitting area 212 to light up. During operation, as the driving current increases, the LED beads 213 become brighter and their temperature rises, especially the beads 213 in the middle. This causes a temperature difference between the outer light source 210 and the inner light source 210, which often reaches a temperature difference of 10-30 degrees Celsius. Excessive temperature can damage the lifespan of the LED beads 213. To avoid this situation, the light-emitting circuit board 220 reduces the driving current of the first light-emitting area 211, so that the temperature of the outer LED beads 213 is similar to that of the inner LED beads 213. This method effectively solves the problem of low luminous efficiency and wasted cost caused by reducing the driving current of all LED beads 213.
[0068] like Figure 6-7 As shown, the first collimation component 230 has multiple first collimation lens units 231, each corresponding to a lamp bead 213. The second collimation component 240 includes a main body 242 and second collimation lens units 241 matching the number of the first collimation lens units 231. Through the first collimation component 230 and the second collimation component 240, the emitted light is converted into parallel light or tends to be parallel light.
[0069] like Figure 5 , 8As shown in Figures 10-11, the optical integrating component 300 includes a substrate 310 and an opening 320 penetrating the substrate 310. The substrate 310 includes a functional surface 311 and a base plane 312. A first compound eye array 3111 is provided on the functional surface 311. The substrate 310 forms an optical integrating region, and the opening 320 forms a beam adjustment region. The light flux passing through the beam adjustment region is greater than the light flux of the optical integrating region. The shape of the beam adjustment region matches the shape of the optical integrating component 300. The optical integrating region can be a regular polygon, a circle, a hexagon, etc. Similarly, the beam adjustment region can be a regular polygon, a circle, a hexagon, etc., and its size accounts for one-tenth to one-half of the entire optical integrating component 300. When the light source assembly 200 emits low beam, the controller controls the second light-emitting area 212 to emit light, reduces the driving current of the first light-emitting area 211, and the beam of the second light-emitting area 212 is equalized through the optical integration area. The first light-emitting area 211 passes through the beam adjustment area, and the final low beam has high uniformity. When the light source assembly 200 emits high beam, the controller controls the second light-emitting area 212 to turn off, increases the driving current of the first light-emitting area 211, enhances the beam energy of the first light-emitting area 211, and the beam passes through the beam adjustment area, is not affected by the components, and maintains the original light effect.
[0070] In addition, to improve the equalization effect of the beam, such as Figure 5 and 11 As shown in Figure -12, a second optical element 321 can also be provided at the opening 320. The second optical element 321 is a compound eye lens, which includes a second compound eye array. The focal length of the microlens unit of the second compound eye array, i.e., the focal length of the central region, is greater than the focal length of the microlens unit of the first compound eye array 3111. When emitting near light, the weaker light emitted by the first light-emitting area 211 is equalized by passing through the second optical element 321 and converged with the equalized beam of the second light-emitting area 212, further improving the beam uniformity. Moreover, providing a compound eye lens at the opening 320 can maintain the stability of the entire optical integrating component 300 and solve the problem of uneven stress on the optical integrating component 300 caused by the opening 320, which makes it prone to breakage.
[0071] like Figure 2 and 8 As shown in Figure 9, the bracket 330 is used to fix two or more integrating elements. The integrating elements are spaced apart on the bracket 330, with adjacent integrating elements facing each other. When the integrating element is a compound eye lens, adjacent integrating elements form opposing double compound eye lenses, resulting in better beam uniformity. At least one integrating element has a beam adjustment area of opening 320, and at least one integrating element disposed between opening 320 and focusing assembly 400 has a beam adjustment area of compound eye lens. Opening 320 is used for light transmission and can reduce light loss, while compound eye lens is used to eliminate the edge perception of the beam and equalize the beam.
[0072] Example 3 like Figure 1-2 As shown, an optical module, serving as a stage light, includes a housing 100, a light source assembly 200, an optical integrating assembly 300, and a focusing assembly 400. The light source assembly 200, the optical integrating assembly 300, and the focusing assembly 400 are disposed within the housing 100. The light beam emitted by the light source 210 module passes sequentially through the optical integrating assembly 300 and the focusing assembly 400. The optical integrating assembly 300 forms an optical channel connecting the light source assembly 200 and the focusing assembly 400.
[0073] like Figure 3-5 As shown, the light source assembly 200 includes a light source 210, a light-emitting circuit board 220, a first collimator 230, and a second collimator 240. The light source 210 is arranged in an array on the light-emitting circuit board 220. The light source 210 can be selected from LED beads 213. The light source 210 can be divided into multiple light-emitting areas. Taking two light-emitting areas as an example, it is divided into a first light-emitting area 211 and a second light-emitting area 212. The first light-emitting area 211 is located in the middle, and the second light-emitting area 212 surrounds the first light-emitting area 211. When low beam is needed, the controller controls the LED beads 213 in the first light-emitting area 211 and the second light-emitting area 212 to light up. During operation, as the driving current increases, the LED beads 213 become brighter and their temperature rises, especially the beads 213 in the middle. This causes a temperature difference between the outer light source 210 and the inner light source 210, which often reaches a temperature difference of 10-30 degrees Celsius. Excessive temperature can damage the lifespan of the LED beads 213. To avoid this situation, the light-emitting circuit board 220 reduces the driving current of the first light-emitting area 211, so that the temperature of the outer LED beads 213 is similar to that of the inner LED beads 213. This method effectively solves the problem of low luminous efficiency and wasted cost caused by reducing the driving current of all LED beads 213.
[0074] like Figure 6-7 As shown, the first collimation component 230 includes a main body 242 and a first collimation lens unit 231, with each first collimation lens unit 231 corresponding to a lamp bead 213. The second collimation component 240 includes a second collimation lens unit 241 that matches the number of the first collimation lens units 231. Through the first collimation component 230 and the second collimation component 240, the emitted light is converted into parallel light or tends to be parallel light.
[0075] like Figure 5 , 8As shown in Figures 10-11, the optical integrating component 300 includes a substrate 310 and an opening 320 penetrating the substrate 310. The substrate 310 includes a functional surface 311 and a base plane 312. A first compound eye array 3111 is provided on the functional surface 311. The substrate 310 forms an optical integrating region, and the opening 320 forms a beam adjustment region. The light flux passing through the beam adjustment region is greater than the light flux of the optical integrating region. The shape of the beam adjustment region matches the shape of the optical integrating component 300. The optical integrating region can be a regular polygon, a circle, a hexagon, etc. Similarly, the beam adjustment region can be a regular polygon, a circle, a hexagon, etc., and its size accounts for one-tenth to one-half of the entire optical integrating component 300. When the light source assembly 200 emits low beam, the controller controls the second light-emitting area 212 to emit light, reduces the driving current of the first light-emitting area 211, and the beam of the second light-emitting area 212 is equalized through the optical integration area. The first light-emitting area 211 passes through the beam adjustment area, and the final low beam has high uniformity. When the light source assembly 200 emits high beam, the controller controls the second light-emitting area 212 to turn off, increases the driving current of the first light-emitting area 211, enhances the beam energy of the first light-emitting area 211, and the beam passes through the beam adjustment area, is not affected by the components, and maintains the original light effect.
[0076] In addition, to improve the equalization effect of the beam, such as Figure 5 and 11 As shown in Figure -13, a third optical element 322 can also be provided at the opening 320. The third optical element 322 can be a lens, a frosted lens, or a diffuser lens. The luminous transmittance of the light beam is ensured by the third optical element 322. In addition, providing the third optical element 322 at the opening 320 can maintain the stability of the entire optical integrating assembly 300 and solve the problem of uneven stress on the optical integrating assembly 300 caused by the opening 320, which makes it prone to breakage.
[0077] like Figure 2 and 8 As shown in Figure 9, the bracket 330 is used to fix two or more integrating elements. The integrating elements are spaced apart on the bracket 330, with adjacent integrating elements facing each other. When the integrating element is a compound eye lens, adjacent integrating elements form opposing double compound eye lenses, resulting in better beam uniformity. At least one integrating element has a beam adjustment area of opening 320, and at least one integrating element disposed between opening 320 and focusing assembly 400 has a beam adjustment area of compound eye lens. Opening 320 is used for light transmission and can reduce light loss, while compound eye lens is used to eliminate the edge perception of the beam and equalize the beam.
[0078] Example 4 like Figure 5 and 14As shown in Figure 15, a light-emitting device 500 includes an optical module as described in Embodiment 2 or 3, and further includes a controller, a fixed lens assembly 510, a zoom lens assembly 520, and a focusing lens assembly 530. The zoom lens assembly 520 is disposed between the fixed lens assembly 510 and the focusing lens assembly 530, and the zoom lens assembly 520 is movable. The optical module is connected to the controller, and the optical module emits a light beam that passes sequentially through the focusing lens assembly 530, the zoom lens assembly 520, and the fixed lens assembly 510. When the distance between the zoom lens assembly 520 and the fixed lens assembly 510 and the focusing lens assembly 530 is changed, the emitted light angle of the light-emitting device 500 also changes accordingly. As the zoom lens assembly 520 gets closer to the focusing lens assembly 530, the emitted light gradually becomes near beam. At this time, the controller controls the driving current of the first light-emitting area 211 to decrease and controls the second light-emitting area 212 to emit a beam, achieving the effect of balancing the near beam. As the zoom lens assembly 520 gets closer to the fixed lens assembly 510, the emitted light gradually becomes far beam. When the emitted light is far beam, the controller controls the second light-emitting area 212 to turn off, while slowly increasing the driving current of the first light-emitting area 211 to ensure the light density of the far beam.
