Description

Multifunctional light source system Technical Field

[0001] This invention relates to the field of optical technology, and more specifically, to a multifunctional light source system. Background Technology

[0002] Stage lighting, cultural and tourism landscape lighting, architectural art lighting, and searchlights are currently the main application areas for high-power LED light sources. For stage lighting, the core light source system of existing high-power stage lighting sources on the market basically includes an LED array light source, a collimation / collection structure, a homogenizing lens structure, and a converging lens structure. Each light source in the LED array light source emits a beam of light. The collimation / collection structure collimates the beam emitted by each light source, converting the originally Lambertian beam into parallel or near-parallel light. The homogenizing lens structure homogenizes the beam after the collimation / collection structure, making the light more uniform. The converging lens focuses the homogenized light onto a predetermined focal plane to obtain a very uniform light spot. This light source system can produce a very strong beam of light and has a long illumination distance, and can also be applied to other lighting fields, such as landscape lighting, architectural lighting, searchlights, and drone lighting.

[0003] However, most high-power stage lighting systems are currently single-mode, meaning the LEDs in the LED array are all the same, and each system can only emit one type of light spot through a converging lens, as seen in patents CN207486478U and CN207486718U. In recent years, a small number of dual-mode stage lighting systems have been introduced to the market. The difference between these and traditional high-power stage lighting systems lies in: 1) the LED array includes two different types of light emitters; 2) the collimation / collection structure is movable relative to the LED array, allowing the lens unit on the collimation / collection structure to be aligned with either of the two light emitters. For example, when the lens unit of the collimation / collection structure is aligned with the first light emitter, a high color rendering index (CRI) is achieved; when aligned with the second light emitter, a high brightness is achieved. However, the aforementioned dual-mode stage lighting sources can only achieve two different lighting effects, still failing to meet the needs of a wider range of lighting effects and lacking sufficient functionality. This is because if an LED array light source uses three or more LED emitters, the maximum distance the collimation / collecting structure can move is relatively large. When the collimation / collecting structure is aligned with the optical center of the outermost LED emitter, the lens unit on the collimation / collecting structure will experience a significant offset relative to the homogenizing and converging lens structures, resulting in severe optical axis deflection. This causes beam unevenness and loss of optical spread, affecting luminous efficiency. The more types of LED emitters there are, the more severe the deflection phenomenon and the greater the loss of optical spread. Therefore, current stage lighting systems cannot simultaneously achieve both diverse lighting effects and superior optical performance. This is a problem inherent in most high-power light sources with a strong beam projection. Thus, there is a need to find a light source system that possesses extremely strong beam projection, a long illumination distance, more diverse lighting effects, and excellent optical performance. Summary of the Invention

[0004] This invention aims to overcome at least one of the shortcomings of the prior art and provide a multifunctional light source system to solve the problem that existing high-power light source systems with beam-like characteristics cannot simultaneously achieve diverse luminous effects and excellent optical performance. The technical solution adopted by this invention is as follows:

[0005] A multifunctional light source system, comprising:

[0006] The light source assembly includes a light source substrate and a first light-emitting body group and a second light-emitting body group located on the light source substrate. The first light-emitting body group and the second light-emitting body group each include a unit substrate and a first light-emitting body and a second light-emitting body disposed on the unit substrate. The first light-emitting body and the second light-emitting body have different luminous efficacy. At least the second light-emitting body is a two-in-one lamp bead or a multi-color lamp bead. The second light-emitting body in the second light-emitting body group is angularly rotated relative to its own luminous center, so that the second light-emitting body in the second light-emitting body group is angularly rotated relative to the second light-emitting body in the first light-emitting body group.

[0007] A collimating lens assembly is disposed in the light emission direction of the light source assembly and is used to converge and / or collimate the light emitted by the light source assembly. The collimating lens assembly includes a collimating lens bracket and a lens unit disposed on the collimating lens bracket.

[0008] An adjustment component is used to adjust the displacement of the collimating lens assembly so that the lens unit is aligned with the first light emitter or the second light emitter; a uniform light lens assembly is disposed behind the collimating lens assembly along the light emission direction of the light source assembly, and is used to uniformly light the light passing through the collimating lens assembly; the uniform light lens assembly includes a compound eye lens holder, and a first compound eye lens and a second compound eye lens respectively disposed on two opposite sides of the compound eye lens holder; both the first compound eye lens and the second compound eye lens are provided with a raised edge, and both sides of the compound eye lens holder are provided with mounting grooves that match the raised edges one by one, and a plurality of mounting grooves are staggered on the two opposite sides of the compound eye lens holder;

[0009] A converging lens assembly is positioned behind the homogenizing lens assembly along the light emission direction of the light source assembly, and is used to converge and emit the homogenized light.

[0010] In one embodiment, the light source assembly includes N groups of light emitters, where N = {3, 4, ..., n-1, n}; the second light emitter in the Nth group of light emitters is rotated relative to its own light emission center, such that the second light emitter in the Nth group of light emitters is rotated at an angle to the second light emitters in other groups of light emitters, where n is a positive integer.

[0011] In one embodiment, the rotation angle of the second light-emitting body in the second light-emitting body group to the rotation angle of the second light-emitting body in the Nth light-emitting body group follows an arithmetic progression.

[0012] In one embodiment, two or N groups of light emitters are arranged in a concentric circular or polygonal circular array on the light source substrate. The first group of light emitters and the second group of light emitters, or the first group of light emitters, the second group of light emitters, ... the nth group of light emitters are sequentially interspersed in each ring of the circular or polygonal circular array in the same order.

[0013] In one embodiment, the light source assembly includes a third light-emitting element group, wherein the second light-emitting element in the second light-emitting element group rotates at an angle of 120° relative to its own light-emitting center, and the second light-emitting element in the third light-emitting element group rotates at an angle of 240° relative to its own light-emitting center.

[0014] In one embodiment, the distance between the light-emitting center of the first light-emitting body and the light-emitting center of the second light-emitting body in the same group of light-emitting bodies is 2mm-5mm.

[0015] In one embodiment, the second light source is an m-in-1 multicolor LED bead, where m ≥ 4, and the second light source includes at least red LED beads, green LED beads, and blue LED beads. The second light source also includes any one or more of lemon green LED beads, amber LED beads, white LED beads, and cyan LED beads.

[0016] In one embodiment, the lens unit includes a first lens unit and a second lens unit. The first lens unit includes a plurality of first lenses, and the collimating lens support has a plurality of through holes arranged in an array for accommodating the first lenses. The second lens unit is an integrally molded lens array structure, which includes a plurality of second lenses. The lens array structure is mounted on the collimating lens support, and the second lenses are arranged in a one-to-one correspondence with the first lenses. In one embodiment, the adjustment assembly includes a sliding member connected to the collimating lens assembly, a guide structure for guiding the displacement of the sliding member, and a driving member for providing driving force for the displacement of the sliding member.

[0017] In one embodiment, the sliding member is detachably connected to the collimating lens assembly, or the sliding member is integrally formed with the collimating lens assembly.

[0018] In one embodiment, the guide structure includes a linear optical axis that slides with the sliding member, and an optical axis bracket for mounting the linear optical axis.

[0019] In one embodiment, the drive unit includes two oppositely arranged solenoid valves, the core extension and retraction states of the two oppositely arranged solenoid valves being opposite; or, the drive unit includes two oppositely arranged stepper motors.

[0020] In one embodiment, the number of adjustment components is two sets, and the two sets of adjustment components are located on opposite sides of the collimating lens assembly.

[0021] In one embodiment, the distance between the planes containing the mounting slots on two opposite sides of the compound eye lens holder is in the range of 0.3mm-0.7mm.

[0022] In one embodiment, the convex edge includes one or more of a quadrilateral convex edge, a triangular convex edge, and / or an arcuate convex edge. In one embodiment, the first compound eye lens and the second compound eye lens have the same shape and parameters, with the lens unit surface of the first compound eye lens facing the collimating lens assembly, and the lens unit surface of the second compound eye lens facing the converging lens assembly.

[0023] In one embodiment, the distance between the lens unit surface of the first compound eye lens and the focal plane of the second compound eye lens is 0 to 0.2 mm, and the distance between the lens unit surface of the second compound eye lens and the focal plane of the first compound eye lens is 0 to 0.2 mm.

[0024] In one embodiment, both the first and second compound eye lenses are composed of integrally formed compound eye lens units arranged in an array, and the distance between the vertices of two adjacent compound eye lens units ranges from 1.5 mm to 2.4 mm.

[0025] Compared with the prior art, the beneficial effects of the present invention include at least:

[0026] The multifunctional light source system of this technical solution sets at least two groups of light-emitting bodies, and each group of light-emitting bodies includes a first light-emitting body and a second light-emitting body that can emit different light effects. At least the second light-emitting body is a two-in-one lamp bead or a multi-color lamp bead that combines multiple functions. By adjusting the collimating lens assembly with the adjustment component to align with different light-emitting bodies, the light emission mode of the multifunctional light source system can be switched, thereby achieving a variety of light effects. Since the second light source is a two-in-one LED or a multi-color LED, to avoid the situation where not all the LEDs in the second light source are lit and the same LED in each group of second light sources is lit, the light spot only illuminates at the same position of the lens unit of the collimating lens assembly, or to avoid the same LEDs in the second light source being imaged at the same position on the focal plane when they are lit simultaneously, this technical solution rotates the second light source in the second light source group relative to its own light-emitting center. This allows the same LEDs to illuminate at different positions on the lens unit of the collimating lens assembly when not all the LEDs in the second light source are lit and the same LEDs in each group are lit. When all the LEDs in the second light source are lit, the same LEDs are imaged at different positions on the focal plane. This results in different imaging positions and angles of the lit LEDs on the preset plane, thus achieving the effect of homogenizing the light spot. Furthermore, since at least the second light source is a two-in-one LED or a multi-color LED, the second light source can be selected to light up individually or several of them at the same time. Moreover, the power of each LED can be different, and various light mixing effects can be created by arranging and combining them, thereby achieving more light-emitting effects.

[0027] Furthermore, the homogenizing lens assembly in this technical solution consists of a pair of parallel compound eye lenses. Compared to a single compound eye lens, this technical solution, by using a pair of compound eye lenses, can achieve better homogenization of the collimated beam. Moreover, given the overall size of the homogenizing lens assembly, the more compound eye lens units in the first and second compound eye lenses, the better the beam segmentation effect after passing through the collimating lens assembly, resulting in a more uniform emitted light spot and better light output. However, with an increased number of compound eye lens units, the size of a single compound eye lens unit will decrease while maintaining the overall size of the homogenizing lens assembly. Simultaneously, the focal length of each compound eye lens unit must also decrease. To further homogenize the incident parallel or near-parallel light before emitting parallel light, the spacing between the first and second compound eye lenses needs to be reduced. However, this would result in an excessively thin compound eye lens support, making it difficult to guarantee the strength of the support. Therefore, this technical solution improves the overall shape of the first compound eye lens, the second compound eye lens, and the compound eye lens holder. Both the outer contours of the first and second compound eye lenses are provided with raised edges, and the compound eye lens holder has multiple mounting slots on both sides that mate with the raised edges. These mounting slots are staggered on opposite sides of the compound eye lens holder. That is, in the optical axis direction parallel to either the first or second compound eye lens, the compound eye lens holder only needs to have a mounting slot on one side at the same optical axis position. This avoids the problem of excessively thin compound eye lens holders caused by symmetrically opposite mounting slots on both sides. This technical solution can ensure the thickness and strength of the compound eye lens holder while allowing the first and second compound eye lenses to be closer together. The number of compound eye lens units on the compound eye lenses can be set sufficiently to further ensure beam homogenization, thereby ensuring the light output effect of the light source system. In addition, compared with traditional compound eye lens pairs, the first and second compound eye lenses in this technical solution need to correspond to staggered mounting slots. Therefore, the convex edges are not continuously arranged around the outer contour of the compound eye lens, but are arranged in the form of multiple convex edges on the outer contour. Thus, it is lighter than traditional compound eye lens pairs, reducing the overall weight of the multifunctional light source system.

[0028] Therefore, this technical solution not only achieves diverse luminous effects but also ensures excellent light output, resulting in a more uniform light spot and a fuller beam. When applied to stage lighting, landscape lighting, drone lighting, and other fields, the emitted light not only has a strong beam effect but also diverse light output effects, meeting the needs of large-scale performances or festival celebrations and enhancing public participation and happiness. When applied to searchlighting, it provides support for search and rescue operations at night or in inclement weather, and the light color can be adjusted according to the climate. For example, in rainy or foggy weather, the light can be adjusted to a more penetrating yellow light to meet work requirements. Attached Figure Description

Detailed Implementation

[0042] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the invention. To better illustrate the following embodiments, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions; it is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0043] A multifunctional light source system, as shown in Figures 1-7, includes:

[0044] The light source assembly 100 includes a light source substrate and a first light-emitting body group 120 and a second light-emitting body group 130 located on the light source substrate. The first light-emitting body group 120 and the second light-emitting body group 130 each include a unit substrate 121 and a first light-emitting body 122 and a second light-emitting body 123 disposed on the unit substrate 121. At least the second light-emitting body 123 is a two-in-one lamp bead or a multi-color lamp bead. The second light-emitting body 123 in the second light-emitting body group 130 is angularly rotated relative to its own light-emitting center, so that the second light-emitting body 123 in the second light-emitting body group 130 is angularly rotated with the second light-emitting body 123 in the first light-emitting body group 120.

[0045] A collimating lens assembly 200 is disposed in the light emission direction of the light source assembly 100 and is used to converge and / or collimate the light emitted by the light source assembly 100. The collimating lens assembly 200 includes a collimating lens bracket 210 and a lens unit disposed on the collimating lens bracket 210.

[0046] The adjustment component 300 is used to adjust the displacement of the collimating lens assembly 200 so that the lens unit is aligned with the first light-emitting body 122 or the second light-emitting body 123.

[0047] A homogenizing lens assembly 400 is disposed behind the collimating lens assembly 200 along the light emission direction of the light source assembly 100, and is used to homogenize the light rays passing through the collimating lens assembly 200. The homogenizing lens assembly 400 includes a compound eye lens holder 410, and a first compound eye lens 420 and a second compound eye lens 430 respectively disposed on two opposite sides of the compound eye lens holder 410. Both the first compound eye lens 420 and the second compound eye lens 430 are provided with a protruding edge 401, and both sides of the compound eye lens holder 410 are provided with mounting grooves 411 that match the protruding edge 401 one by one. A plurality of mounting grooves 411 are staggered on the two opposite sides of the compound eye lens holder 410.

[0048] A converging lens assembly 500 is disposed behind the homogenizing lens assembly 400 along the light emission direction of the light source assembly 100, and is used to converge and emit the homogenized light.

[0049] The multifunctional light source system of this embodiment sets at least two groups of light emitters, and each group of light emitters includes a first light emitter 122 and a second light emitter 123 that can emit different light effects (different light effects can be different color temperatures, different color rendering indexes, different colors, different spot sizes, different spot shapes, different spot sizes, or different beam effects, etc. As long as the optical parameters or optical effects of the light emitted by the light emitter are any different, they can be considered as different light effects). At least the second light emitter 123 is a two-in-one lamp bead or a multi-color lamp bead that combines multiple functions. The collimating lens assembly 200 is adjusted by the adjustment component 300 to be aligned with different light emitters to switch the light effects, thereby achieving a variety of light effects. Since the second light emitter 123 is a two-in-one LED or a multi-color LED, in order to avoid the situation where not all the LEDs in the second light emitter 123 are lit and the same LEDs in each group of second light emitters 123 are lit, the light spot only lights up at the same position of the lens unit of the collimating lens assembly 200, or to avoid the poor light mixing effect when the LEDs in the second light emitter are lit up at the same time, this embodiment rotates the second light emitter 123 in the second light emitter group 130 relative to its own light emission center. So when not all the LEDs in the second light emitter 123 are lit and the same LEDs in each group of second light emitters 123 are lit, the LEDs can light up at different positions of the lens unit of the collimating lens assembly 200, or when all the LEDs in the second light emitter are lit, the same LEDs are imaged at different positions of the focal plane. This results in the imaged positions and angles of the lit LEDs on the preset plane being different, and the superposition of multiple light spots with different imaged positions and angles achieves the effect of homogenizing the light spot. Furthermore, since at least the second light-emitting element 123 is a two-in-one LED or a multi-color LED, the second light-emitting element 123 can be selected to light up individually or several of them simultaneously. Each LED can also have a different power, allowing for various light mixing effects and thus achieving more light-emitting effects, greatly enriching the variety of light effects. Additionally, the light-diffusing lens assembly 400 in this embodiment is a pair of parallel compound eye lenses. Compared to a single compound eye lens, this embodiment, by setting a pair of compound eye lenses, can better uniformize the collimated beam. Moreover, the more compound eye lens units in the first compound eye lens 420 and the second compound eye lens 430, the better the beam segmentation effect after passing through the collimating lens assembly 200, resulting in a more uniform light spot and better light output. However, with the increase in the number of compound eye lens units, the size of the compound eye lens unit will decrease if the overall size of the homogenizing lens assembly 400 is the same. At the same time, the focal length of the compound eye lens unit will also decrease. In order for the homogenizing lens assembly 400 to further homogenize the incident parallel or near-parallel light and then emit parallel light, the distance between the first compound eye lens 420 and the second compound eye lens 430 needs to be reduced. However, this will result in the compound eye lens support 410 being too thin, making it difficult to guarantee the strength of the compound eye lens support 410.Therefore, this embodiment improves the overall shape of the first compound eye lens 420, the second compound eye lens 430, and the compound eye lens support 410. Both the outer contours of the first compound eye lens 420 and the second compound eye lens 430 are provided with protruding edges 401, and both sides of the compound eye lens support 410 are provided with multiple mounting grooves 411 that mate with the protruding edges 401. These mounting grooves 411 are staggered on opposite sides of the compound eye lens support 410. That is, in the optical axis direction parallel to either the first or second compound eye lens 420, the compound eye lens support 410 only needs to have a mounting groove 411 on one side at the same optical axis position. This avoids the problem of the compound eye lens support 410 being too thin due to the symmetrical arrangement of mounting grooves 411 on both sides in the optical axis direction parallel to either the first or second compound eye lens 420. This embodiment allows the first compound eye lens 420 and the second compound eye lens 430 to be placed closer together while ensuring the thickness and strength of the compound eye lens holder 410. The number of compound eye lens units on the compound eye lens can be set sufficiently to further ensure beam homogenization, thereby guaranteeing the light output performance of the multifunctional light source system. Furthermore, compared to traditional compound eye lens pairs, the first compound eye lens 420 and the second compound eye lens 430 in this technical solution need to correspond to staggered mounting slots. Therefore, their convex edges are not continuously arranged around the outer contour of the compound eye lens, but rather arranged as multiple convex edges. This results in a lighter weight compared to traditional compound eye lens pairs, reducing the overall weight of the multifunctional light source system.

[0050] Therefore, this implementation not only achieves diverse luminous effects but also ensures excellent light output, resulting in a more uniform light spot and a fuller beam. When applied to stage lighting, landscape lighting, drone lighting, and other fields, the emitted light not only has a strong beam effect but also diverse light output effects, meeting the needs of large-scale celebrations and enhancing public participation and well-being. When applied to searchlighting, it provides support for search and rescue operations at night or in inclement weather, and the light color can be adjusted according to the climate. For example, in rainy or foggy weather, the light can be adjusted to a more penetrating yellow light to meet work requirements.

[0051] In this embodiment, the unit substrate 121 is a ceramic substrate. Ceramic has strong heat resistance and good thermal conductivity, which enables the heat generated by the first light emitter and the second light emitter to be quickly conducted to the light source substrate 110, and then transferred to the outside or to the heat dissipation component for heat dissipation through the light source substrate 110.

[0052] As shown in Figures 3 and 4 in conjunction with Figure 8, the light source assembly 100 of this embodiment includes N groups of light emitters, where N = {3, 4, ..., n-1, n}. The second light emitter 123 in the Nth group of light emitters is rotated relative to its own light emission center, such that the second light emitter 123 in the Nth group of light emitters is rotated at an angle to the second light emitter 123 in other groups of light emitters, where n is a positive integer. For example, in this embodiment, taking N = 3 as an example, the light source assembly 100 includes 3 groups of light emitters. The second light emitter 123 in the third group of light emitters 140 is rotated relative to its own light emission center, such that the second light emitter 123 in the third group of light emitters 140 is rotated at an angle to the second light emitter 123 in the first group of light emitters 120, and also to the second light emitter 123 in the second group of light emitters 130. In other embodiments, to further make the light spot on the focal plane more uniform and full, N can be any other positive integer greater than 3.

[0053] In this embodiment, the rotation angle of the second light-emitting element 123 in the second light-emitting element group 130 and the rotation angle of the second light-emitting element 123 in the Nth light-emitting element group follow an arithmetic progression. Taking N=3 in this embodiment as an example, the rotation angle of the second light-emitting element 123 in the second light-emitting element group 130 and the rotation angle of the second light-emitting element 123 in the third light-emitting element group 140 follow an arithmetic progression. In other embodiments, when N=4, the rotation angles of the second light-emitting body 123 in the second light-emitting body group 130, the second light-emitting body 123 in the third light-emitting body group 140, and the second light-emitting body 123 in the fourth light-emitting body group follow an arithmetic progression; when N=5, the rotation angles of the second light-emitting body 123 in the second light-emitting body group 130, the second light-emitting body 123 in the third light-emitting body group 140, the second light-emitting body 123 in the fourth light-emitting body group, and the second light-emitting body 123 in the fifth light-emitting body group follow an arithmetic progression... and so on when N>5.

[0054] Since this embodiment includes three different light-emitting body groups, in order to make the light more uniform, the rotation angle of the second light-emitting body 123 in each light-emitting body group relative to its own light-emitting center can be divided by 360°, and when the common difference of the arithmetic sequence is 360° / N, the light emitted by the light source assembly 100 is more uniform. That is, when N=3, the rotation angle of the second light-emitting body 123 on the second light-emitting body group 130 relative to its own light-emitting center is 120°, and the rotation angle of the second light-emitting body on the third light-emitting body group 140 relative to its own light-emitting center is 240°; when N=4, the rotation angles of the second light-emitting bodies in different light-emitting body groups are 90°, 180°, and 270°, respectively; when N=5, the rotation angles are 72°, 144°, 216°, and 288°, respectively; and so on. As shown in Figures 9 and 10 (Figure 10 simplifies the illustration of different light-emitting groups to make the arrangement pattern of the light-emitting groups clearer), in this embodiment, two or N groups of light-emitting groups are arranged in a concentric circular or polygonal circular array on the light source substrate. The first light-emitting group 120 and the second light-emitting group 130, or the first light-emitting group 120, the second light-emitting group 130 and the third light-emitting group 140, or the first light-emitting group 120, the second light-emitting group 130... the nth light-emitting group are sequentially interspersed in the same order in each ring of the circular or polygonal circular array. Specifically, in this embodiment, three groups of light-emitting groups are arranged in a concentric polygonal circular array on the light source substrate. The first light-emitting group 120, the second light-emitting group 130 and the third light-emitting group 140 are sequentially interspersed in the same order in each ring of the polygonal circular array, and the number of the first light-emitting group 120, the second light-emitting group 130 and the third light-emitting group 140 in the same ring is the same to ensure the light emission efficiency.

[0055] In this embodiment, the polygonal ring is a hexagonal ring; in other embodiments, it can be configured as other polygonal ring arrays. Alternatively, in other embodiments, it can be configured as a series of light-emitting groups arranged concentrically in a ring on the light source substrate, with the first light-emitting group 120, the second light-emitting group 130...the nth light-emitting group interspersed in each ring of the ring array.

[0056] In this embodiment, the distance between the light-emitting centers of the first light-emitting element 122 and the second light-emitting element 123 in the same group of light-emitting elements is 2mm-5mm. Specifically, in this embodiment, the distance between the light-emitting centers of the first light-emitting element 122 and the second light-emitting element 123 in the same group of light-emitting elements is 3mm, that is, the moving distance of the collimating lens assembly 200 is 3mm. This ensures that the moving distance of the collimating lens assembly 200 is not too large, the optical expansion is almost zero, and the operability of the chip package in the light-emitting elements is also guaranteed.

[0057] In this embodiment, the second light-emitting element 123 is an m-in-1 multi-color LED bead, where m ≥ 4. The second light-emitting element 123 includes at least red, green, and blue LED beads, and also includes any one or more of lemon green, amber, white, and cyan LED beads. Specifically, the second light-emitting element 123 in this embodiment is an RGBL four-in-1 LED bead (denoted as red, green, blue, and lemon green four-in-1 LED bead). The luminous effect of the RGBL four-in-1 LED bead can meet most lighting needs, and when RGBL lights are lit simultaneously, their superimposed effect is close to full-spectrum white light, with good spectral continuity, high color rendering index, and greater energy efficiency and environmental friendliness. In other embodiments, the second light-emitting element can be an RGBA four-in-1 LED bead or other multi-in-1 LED beads.

[0058] In this embodiment, the first light-emitting element 122 is a single white light bulb. In other embodiments, the first light-emitting element may also be a two-in-one or multi-in-one white light bulb. The specific design can be adjusted according to actual needs.

[0059] Since the first light-emitting element 122 in this embodiment uses a white light LED and the second light-emitting element 123 uses an RGBL four-in-one LED, the collimating lens assembly 200 can be moved relative to the light source assembly 100 by adjusting the adjustment component 300, and the lens unit of the collimating lens assembly 200 can be aligned with the optical center of the white light LED or the RGBL four-in-one LED respectively, so that the switching between single white light mode and multi-color mode can be realized.

[0060] In this embodiment, the white LED uses a single circular chip. The RGBL LED chip has a 1mm x 1mm square emitting surface, with a chip spacing of 0.1mm, resulting in a total emitting surface of approximately 2.1mm x 2.1mm. The white LED chip has a 2.3mm emitting surface, and the two groups of LEDs are spaced 3mm apart. To achieve different effects, the collimating lens assembly 200 is aligned with different LEDs. For example, to achieve a white LED effect, the collimating lens assembly 200 is aligned with the optical center of the white LED. To achieve a red, green, blue, or lemon-green effect, the collimating lens assembly 200 is aligned with the optical center of the RGBL four-in-one chip, and one color of LED is illuminated. Furthermore, besides individual RGBL illumination, two, three, or all four RGBL LEDs can be illuminated simultaneously. The power of each RGBL chip can also be different. Combining RGBLs with different powers can achieve a wide variety of light mixing effects, thus enabling various different lighting effects. Figure 12 shows the optical simulation diagram of the light source system on the focal plane when the collimating lens assembly 200 is aligned with the second light source 123 and the second light source is an RGBL LED bead lit at full power. As can be seen from the figure, for RGBL four-color LED beads, by rotating the second light source relative to its own light-emitting center and using a specially designed compound eye lens assembly to homogenize the light, the imaging uniformity on the focal plane is particularly good, indicating that the light mixing effect of RGBL four-color LED beads is very good.

[0061] The lens unit described in this embodiment includes a first lens unit 221 and a second lens unit 222. The first lens unit 221 includes a plurality of first lenses, and the collimating lens support 210 is provided with a plurality of through holes arranged in an array for accommodating the first lenses. The second lens unit 222 is an integrally molded lens array structure, which includes a plurality of second lenses. The lens array structure is mounted on the collimating lens support 210, and the second lenses are arranged in a one-to-one correspondence with the first lenses. By setting the first and second lenses, the light collection and collimation effect of the collimating lens assembly 200 is improved, resulting in nearly parallel or parallel light rays.

[0062] The adjustment assembly 300 of this embodiment includes a sliding member 310 connected to the collimating lens assembly 200, a guide structure for guiding the displacement of the sliding member 310, and a driving member 330 for providing driving force for the displacement of the sliding member 310. The driving member 330 drives the sliding member 310 to move along the guide direction of the guide structure, thereby causing the collimating lens assembly 200 connected to the sliding member 310 to move as well, so that the lens unit on the collimating lens assembly 200 can be aligned with the first light emitter or the second light emitter. Specifically, the driving direction of the driving member 330 is perpendicular to the principal optical axis of the collimating lens assembly 200, that is, the guide direction of the guide structure is perpendicular to the principal optical axis of the collimating lens assembly 200.

[0063] In this embodiment, the sliding member 310 and the collimating lens assembly 200 are detachably connected by bolts, facilitating maintenance and replacement and reducing subsequent maintenance costs. In other embodiments, other detachable connection methods can be used, such as snap-fit, or the sliding member 310 and the collimating lens assembly 200 can be integrally formed to simplify the assembly process. As shown in Figure 11 in conjunction with Figure 1, the guide structure in this embodiment includes a linear optical axis 321 that slides with the sliding member 310, and an optical axis bracket 322 for mounting the linear optical axis 321. Furthermore, the sliding member 310 is also provided with a bearing 311 that cooperates with the linear optical axis 321, so that the sliding member 310 can not only move stably along the linear optical axis 321, but also avoids the sliding member 310 jumping in the direction perpendicular to the linear optical axis 321, which would affect the collimating and light-receiving function of the collimating lens assembly 200.

[0064] The optical axis support 322 of this embodiment includes a first support and a second support. The first support and the second support are respectively disposed at both ends of the linear optical axis 321. This not only ensures the stable installation of the linear optical axis 321, but also serves as a limiting function. That is, when the sliding member 310 moves to the point where the lens unit is aligned with the first light-emitting body, it just abuts against the first support, so that the sliding member 310 can be stabilized in the current position and ensure the light emission effect. Similarly, when the sliding member 310 moves to the point where the lens unit is aligned with the second light-emitting body, it just abuts against the second support, so that the sliding member 310 can be stabilized in the current position and ensure the light emission effect.

[0065] Furthermore, for ease of assembly and disassembly, both the first and second brackets in this embodiment are engaged with the linear optical axis 321 via grooves. Specifically, the grooves are located at the top of the first and second brackets. After both ends of the linear optical axis 321 are engaged with their corresponding grooves, a pressure plate is used to press the linear optical axis 321 firmly. In addition, the groove design facilitates the installation of the linear optical axis, making installation quick and convenient.

[0066] In this embodiment, the first bracket and the second bracket are integrally formed, which is convenient for disassembly and assembly. In other embodiments, the first bracket and the second bracket can also be set as separate structures, so that the interval between the first bracket and the second bracket can be adjusted according to the moving distance of the sliding member 310 or the size of the sliding member 310.

[0067] The driving component 330 described in this embodiment includes two opposing solenoid valves with opposite core extension / retraction states. That is, when it is necessary to align the lens unit of the collimating lens assembly 200 with the first light-emitting body, the core of one of the solenoid valves retracts, pulling the sliding member 310 to slide until the lens unit is aligned with the first light-emitting body, and the core of the opposing solenoid valve is extended. When it is necessary to align the lens unit of the collimating lens assembly 200 with the second light-emitting body, the core of the other solenoid valve retracts, pulling the sliding member 310 to slide until the lens unit is aligned with the second light-emitting body, and the core of the opposing solenoid valve is extended.

[0068] In addition, to facilitate the installation and connection of the sliding member 310, the sliding member 310 is provided with a protrusion that connects to the iron core, that is, each sliding member 310 is equipped with two protrusions, which are respectively connected to two iron cores arranged opposite to each other.

[0069] In other embodiments, the drive unit 330 may be configured to include two stepper motors arranged opposite each other.

[0070] In this embodiment, there are two sets of adjustment components 300. The two sets of adjustment components 300 are arranged symmetrically on opposite sides of the collimating lens assembly 200. The driving component 330 drives synchronously, thereby making the driving force more balanced, the movement of the collimating lens assembly 200 more stable, and the stability of maintaining the state when the collimating lens assembly 200 is aligned with one of the light-emitting bodies is better.

[0071] In this embodiment, the distance T between the planes containing the mounting grooves 411 on two opposite sides of the compound eye lens holder 410 is in the range of 0.3mm-0.7mm. That is, the distance T between the first compound eye lens 420 and the second compound eye lens 430 is 0.3mm-0.7mm. Specifically, in this embodiment, the distance T between the planes containing the mounting grooves 411 on two opposite sides of the compound eye lens holder 410 is 0.5mm. In other embodiments, it can be adjusted according to the actual situation.

[0072] Since the first light-emitting element group 120, the second light-emitting element group 130, and the third light-emitting element group 140 in the light source assembly 100 of this embodiment are arranged in a hexagonal ring array, in order to improve space utilization, the outer contours of the first compound eye lens 420 and the second compound eye lens 430 in this embodiment are also hexagonal structures, and the hexagonal structure matches the overall outer contour of the hexagonal ring array. A protruding edge 401 is provided on the hexagonal outer contour to serve as a mounting part for mounting to the compound eye lens bracket 410. In this embodiment, there are multiple protruding edges 401; in other embodiments, there may be two.

[0073] In this embodiment, the protruding edge 401 is a quadrilateral protruding edge 401, and the shape of each protruding edge 401 can be adjusted according to the actual situation, that is, each quadrilateral protruding edge 401 can be set to a uniform shape or different shapes. The shape of each mounting groove 411 is also adapted to the shape of the protruding edge 401.

[0074] In other embodiments, the convex edge 401 may be triangular, arc-shaped, or a combination of several convex edge shapes. To simplify the manufacturing process, in this embodiment, the first compound eye lens 420 and the second compound eye lens 430 have the same shape and parameters. The lens unit surface of the first compound eye lens 420 faces the collimating lens assembly 200, and the lens unit surface of the second compound eye lens 430 faces the converging lens assembly 500. The lens unit surface is the surface where the apex of the compound eye lens unit protrusion is located.

[0075] In this embodiment, the lens unit surface of the first compound eye lens 420 is located near the focal plane of the second compound eye lens 430, and the lens unit surface of the second compound eye lens 430 is located near the focal plane of the first compound eye lens 420, so that each group of opposing lens units forms an image at the focal point of the converging lens assembly 500. For example, when the lens unit is hexagonal, each group of hexagonal units forms a hexagonal image at the focal point of the converging lens assembly 500.

[0076] In one embodiment, both the first compound eye lens 420 and the second compound eye lens 430 are composed of an array of integrally formed compound eye lens units. The distance between the vertices of two adjacent compound eye lens units ranges from 1.5mm to 2.4mm, and the distance between the focal plane of the first compound eye lens 420 and the lens unit surface of the second compound eye lens 430 is 0-0.2mm. That is, the error of the lens unit surface of the second compound eye lens 430 being located on the focal plane of the first compound eye lens 420 is allowed to be within 0.2mm. Similarly, the distance between the focal plane of the second compound eye lens 430 and the lens unit surface of the first compound eye lens 420 is 0-0.2mm, and the error of the lens unit surface of the first compound eye lens 420 being located on the focal plane of the second compound eye lens 430 is allowed to be within 0.2mm. This embodiment also includes a housing 600, which encapsulates the aforementioned light source assembly 100, collimating lens assembly 200, adjustment assembly 300, uniform light lens assembly 400, and converging lens assembly 500.

[0077] Furthermore, the converging lens assembly includes a converging lens 510 and a lens retaining ring 520 for fixing the converging lens. Clearly, the above embodiments of the present invention are merely examples for clearly illustrating the technical solution of the present invention, and are not intended to limit the specific implementation of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the claims of the present invention should be included within the protection scope of the claims of the present invention.
