Description

Technical Field

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

[0002] Existing high-power stage lighting systems typically include a light source assembly, a collimating lens assembly, a homogenizing lens assembly, and a converging lens assembly. The light source assembly consists of an array of LED emitters. The collimating lens assembly comprises a lens holder and an array of small lens units mounted on the lens holder, with each small lens unit aligned with a single LED emitter. The homogenizing lens assembly consists of compound eye lens pairs used to homogenize the light. The converging lens assembly consists of a large lens and a lens retainer ring used to collect the homogenized light and converge it to the focal plane. However, existing high-power stage lighting systems generally have a limited range of light emission modes, typically only one. While a few dual-mode high-power stage lighting systems have been introduced in the past two years, they still only support two light emission modes and cannot meet the diverse needs of stage lighting systems. Summary of the Invention

[0003] The present invention aims to overcome at least one of the defects of the prior art and provide a light source system to solve the problem of limited light emission modes of high-power stage lighting light source systems. The light emission modes include at least four types, and the light source system has high light emission efficiency and good optical effect.

[0004] The technical solution adopted in this invention is as follows:

[0005] A light source system includes: a light-emitting component and a collimating lens assembly for converging and / or collimating light rays, a homogenizing lens assembly for homogenizing light rays, and a converging lens assembly for focusing light rays, arranged sequentially along the light emission direction of the light-emitting component. The collimating lens assembly includes a collimating lens support and a lens unit disposed on the collimating lens support.

[0006] The light-emitting component includes a substrate and an array of light-emitting elements arranged on the substrate. The light-emitting elements include at least a first light-emitting element group and a second light-emitting element group. The light-emitting elements include at least a first light-emitting element and a second light-emitting element. At least the second light-emitting element is an N-in-one LED bead, where N≥2. The second light-emitting elements in the first light-emitting element group and the second light-emitting elements in the second light-emitting element group are placed at different angles. When the second light-emitting element in the second light-emitting element group rotates around its center point, it can be placed at the same angle as the second light-emitting element in the first light-emitting element group.

[0007] The uniform light lens assembly includes a first compound eye lens and a second compound eye lens that are parallel to each other and have their lens array surfaces facing away from each other. The gap between the first compound eye lens and the second compound eye lens is 0 to 0.7 mm.

[0008] The light source system further includes an off-axis rotation mechanism, a support frame assembly, and a drive assembly. The support frame assembly is used to support the collimating lens assembly and is rotatably connected to the collimating lens support via the off-axis rotation mechanism. The drive assembly is used to drive the off-axis rotation mechanism to cause the collimating lens assembly to rotate relative to the light-emitting assembly.

[0009] Preferably, the uniform light lens assembly further includes a compound eye lens bracket, with the first compound eye lens and the second compound eye lens mounted on opposite sides of the compound eye lens bracket and the gap between them being 0.3 to 0.7 mm. Both the edge of the first compound eye lens and the edge of the second compound eye lens are provided with protruding edges, and the projections of the protruding edges of the first compound eye lens and the second compound eye lens on the lens array surface of the first compound eye lens are misaligned. Both sides of the compound eye lens bracket are provided with a plurality of mounting grooves that mate with the protruding edges.

[0010] Preferably, the off-axis rotation mechanism includes a first deflection connector, which includes a first rotating shaft and a second rotating shaft arranged parallel but not coaxially. The first rotating shaft is rotatably connected to the collimating lens bracket, and the second rotating shaft is rotatably connected to the support frame assembly.

[0011] Preferably, the deflection axis rotation mechanism further includes a second deflection connector, which includes a third rotating shaft and a fourth rotating shaft arranged parallel but not coaxially. The third rotating shaft is rotatably connected to the collimating lens bracket, and the fourth rotating shaft is rotatably connected to the support frame assembly.

[0012] Preferably, the support frame assembly includes a first support frame with a first through hole and a second support frame with a second through hole, a second rotating shaft inserted into the first through hole, and a fourth rotating shaft inserted into the second through hole.

[0013] Preferably, the first and second through holes are further provided with bearings, and the second and fourth rotating shafts are both inserted into the bearings.

[0014] Preferably, the drive assembly includes a drive member and a transmission member connected to the output end of the drive member, and the first deflection connector is connected to the transmission member.

[0015] Preferably, the transmission component is a worm gear, and the second shaft of the first deflection connector is located at the center of the turbine, and the turbine shaft coincides with the second shaft.

[0016] Preferably, the light source system further includes a limiting component for limiting the rotation of the alignment lens assembly.

[0017] Preferably, the light-emitting component includes M groups of light-emitting bodies. The second light-emitting body in each group has a different placement angle than the second light-emitting body in other groups. When the second light-emitting body in each group rotates around its center point, it can be placed at the same angle as the second light-emitting body in other groups. The placement angles of the second light-emitting bodies in different groups follow an arithmetic sequence pattern, M≥3, and M is a positive integer.

[0018] Preferably, the three groups of light emitters are arranged on the substrate in a concentric polygonal ring array or a concentric circular ring array, and the first group of light emitters, the second group of light emitters, and the third group of light emitters are arranged sequentially in the same order in each ring.

[0019] Preferably, the light-emitting body group further includes a third light-emitting body, and the first light-emitting body, the second light-emitting body, and the third light-emitting body are arranged in a circular arc, and the distance between the first rotating shaft and the second rotating shaft is equal to the radius of the circular arc.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: The light-emitting component of the present invention is provided with an array of light-emitting body groups, each light-emitting body group including at least a first light-emitting body and a second light-emitting body, and is provided with an off-axis rotation mechanism, a support frame assembly, and a drive assembly. The support frame assembly is used to support the collimating lens assembly and is rotatably connected to the collimating lens support through the off-axis rotation mechanism. The drive assembly enables the collimating lens assembly to rotate relative to the light-emitting component, thereby enabling the collimating lens assembly to align with different light-emitting bodies in the light-emitting component, achieving the convergence and / or collimation of light from different light-emitting bodies, resulting in high light-gathering efficiency. Furthermore, since at least the second light-emitting body is an N-in-one LED bead, N≥2, the light-emitting body group includes at least a first light-emitting body group and a second light-emitting body group. The second light-emitting body in the first light-emitting body group and the second light-emitting body in the second light-emitting body group are positioned at different angles, and when the second light-emitting body in the second light-emitting body group rotates around its center point, it can be aligned with the second light-emitting body in the first light-emitting body group. When the collimating lens assembly is aligned with the second light source and not all the LEDs in the second light source are lit, but the same LEDs in each group of the second light source are lit, the light spots emitted by the collimating lens assembly and converging lens assembly will also have different placement angles due to the different placement angles of the second light source. The light spots at different placement angles will overlap, which can better avoid the problem of light spot deflection. Alternatively, when the LEDs in the second light source are lit simultaneously, the same LEDs will be imaged at different positions on the preset plane, so that the angle and position of the lit LEDs on the preset plane are different, which can achieve the effect of homogenizing the light spot on the preset plane. Furthermore, since the gap between the first compound eye lens and the second compound eye lens in the homogenizing lens assembly of this technical solution is 0-0.7mm, this small gap of compound eye lens has a better homogenization effect on light, thus achieving a more uniform light spot. This technical solution uses an eccentric deflection method, resulting in a small light source system with good stability. Attached Figure Description

Detailed Implementation

[0034] 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. Example 1

[0035] like Figures 1 to 3 As shown, this embodiment discloses a light source system, including: a light-emitting component 100 and a collimating lens assembly 200 for gathering and / or collimating light rays, a homogenizing lens assembly 300 for homogenizing light rays, and a converging lens assembly 400 for converging light rays, arranged sequentially along the light emission direction of the light-emitting component 100. The collimating lens assembly 200 includes a collimating lens support 210 and a lens unit disposed on the collimating lens support 210.

[0036] like Figure 4 , Figure 5As shown, the light-emitting component 100 includes a substrate 110 and an array of light-emitting elements 120 disposed on the substrate 110. The light-emitting element group 120 includes at least a first light-emitting element group 121 and a second light-emitting element group 122. The light-emitting element group 120 includes at least a first light-emitting element 101 and a second light-emitting element 102. At least the second light-emitting element 102 is an N-in-one LED, where N≥2. The second light-emitting element 102 in the first light-emitting element group 121 and the second light-emitting element 102 in the second light-emitting element group 122 are placed at different angles. When the second light-emitting element 102 in the second light-emitting element group 122 rotates around its center point, it can be placed at the same angle as the second light-emitting element 102 in the first light-emitting element group 121. Specifically, in this embodiment, the light-emitting body group 120 includes a first light-emitting body group 121, a second light-emitting body group 122, and a second light-emitting body group 123. The light-emitting body group includes a first light-emitting body 101, a second light-emitting body 102, and a third light-emitting body 103. The second light-emitting body 102 includes a four-in-one LED bead. In other embodiments, the number of light-emitting body groups 120 can be two, four, or more, and the number of light-emitting bodies can also be two, four, or more. The number of LED beads in the second light-emitting body can also be two, three, five, or more. More specifically, in this embodiment, the placement angle of the second light-emitting body 102 in each group of light-emitting bodies is different from that in other groups of light-emitting bodies, and the placement angle of the second light-emitting body 102 in each group of light-emitting bodies 120 is consistent with that in other groups of light-emitting bodies 120 when the second light-emitting body 102 in each group of light-emitting bodies 120 rotates around its center point.

[0037] The uniform light lens assembly 300 includes a first compound eye lens 310 and a second compound eye lens 320 that are parallel to each other and have their lens array surfaces facing away from each other. The gap between the first compound eye lens 310 and the second compound eye lens 320 is 0 to 0.7 mm.

[0038] The light source system further includes an off-axis rotation mechanism 500, a support frame assembly 600, and a drive assembly 700 disposed on the substrate 110. The support frame assembly 600 is used to support the collimating lens assembly 200 and is rotatably connected to the collimating lens support 210 through the off-axis rotation mechanism 500. The drive assembly 700 is used to drive the off-axis rotation mechanism 500 to move the collimating lens assembly 200 relative to the light-emitting assembly 100.

[0039] The light-emitting component 100 of the present invention includes a light-emitting element group 120 comprising a first light-emitting element 101, a second light-emitting element 102, and a third light-emitting element 103, and is provided with an off-axis rotation mechanism 500, a support frame assembly 600, and a drive assembly 700. The support frame assembly 600 is used to support the collimating lens assembly 200 and is rotatably connected to the collimating lens bracket 210 through the off-axis rotation mechanism 500. The drive assembly 700 enables the collimating lens assembly 200 to move relative to the light-emitting component 100, thereby enabling the collimating lens assembly 200 to be aligned with different light-emitting elements in the light-emitting component 100, achieving the convergence and / or collimation of light from different light-emitting elements, resulting in high light-gathering efficiency. Since the second light-emitting element 102 is a 4-in-1 LED, when the collimating lens assembly 200 is aligned with the second light-emitting element 102, the lens unit on the collimating lens assembly 200 is aligned with the center of the entire second light-emitting element 102. No single LED in the second light-emitting element 102 is aligned with the center of the lens unit on the collimating lens assembly 200. If the light passes directly through the converging lens assembly 400, the shape of the emitted light spot will be the same as the shape of the LED and a certain degree of eccentricity will occur. To avoid this eccentricity, this technical solution sets the light-emitting element group 120 to include a first light-emitting element group 121, a second light-emitting element group 122, and a third reflector group 123. 23. Furthermore, the second light source 102 in each group of light sources 120 has a different placement angle than the second light source 102 in other groups of light sources 120. When the second light source 102 in each group of light sources 120 rotates around its center point, it can be placed at the same angle as the second light source 102 in other groups of light sources 120. Therefore, the light spots emitted by the lamp beads in the second light source 102 with different placement angles through the converging lens assembly 400 are also eccentric light spots with different rotation angles. These light spots will be superimposed on the focal plane, thereby improving the problem of light spot eccentricity and the problem of the image being the same as the shape of the lamp bead, thus achieving the effect of uniform light spot. Furthermore, this technical solution incorporates a compound eye lens assembly 300 capable of homogenizing light. The compound eye lens assembly 300 further homogenizes parallel or near-parallel light to obtain more uniform parallel light. By setting the gap between the first compound eye lens 310 and the second compound eye lens 320 to 0-0.7 mm, this technical solution can further enhance the light homogenization effect of the compound eye lens assembly 300. This is because, for the first compound eye lens 310 and the second compound eye lens 320, which are parallel to each other and have their lens array surfaces facing away from each other, to achieve a uniform light effect, the smaller the gap between the first compound eye lens 310 and the second compound eye lens 320, and the smaller the small lens units (i.e., compound eye lens units) on the compound eye lenses, the better the uniform light effect. The lens array surface mentioned in this application refers only to the plane where the apex of the protrusion of the compound eye lens is located. In addition, this technical solution adopts an eccentric rotation method, which allows for a smaller spacing between each light-emitting element, resulting in a smaller overall volume of the light source system and good stability during movement.

[0040] Furthermore, such as Figure 10-12 As shown, the homogenizing lens assembly 300 further includes a compound eye lens holder 330. A first compound eye lens 310 and a second compound eye lens 320 are mounted on opposite sides of the compound eye lens holder 330 with a gap of 0.3–0.7 mm between them. Both the edges of the first compound eye lens 310 and the second compound eye lens 320 have protruding edges 301. The projections of the protruding edges 301 of the first compound eye lens 310 and the second compound eye lens 320 on the lens array surface of the first compound eye lens 310 are misaligned. The compound eye lens holder 330 has multiple mounting grooves 331 on both sides that mate with the protruding edges 301. Regarding the movement of the collimating lens assembly relative to the light-emitting assembly, this technical solution employs an eccentric rotation method, resulting in a small light source system size and good stability. Furthermore, when the number of light emitters in the light emitter group 120 exceeds two types, this eccentric rotation method can make the maximum spacing between the light emitters smaller, thereby reducing the maximum offset of the optical axis of the collimating lens assembly 200 relative to the optical axis of the converging lens assembly 400.

[0041] This embodiment improves the structure and shape of the compound eye lens holder 330, the first compound eye lens 310, and the second compound eye lens 320. A raised edge 301 is provided on the edge of both the first and second compound eye lenses 310. The projections of the raised edges 301 of the first and second compound eye lenses 320 onto the array surface of the first compound eye lens 310 are misaligned. Multiple mounting grooves 331 that mate with the raised edges 301 are provided on both sides of the compound eye lens holder 330. This allows the mounting grooves 331 on both sides of the compound eye lens holder 330 to be misaligned. Compared to a design with symmetrically arranged mounting grooves 331 on both sides, this misalignment design reduces the distance between the two compound eye lenses while ensuring that the overall thickness of the compound eye lens holder 330 is not significantly affected. In other words, this embodiment can ensure the strength and thickness of the compound eye lens support 330 on the one hand, and reduce the distance between the first compound eye lens 310 and the second compound eye lens 320 on the other hand, so that the number of compound eye lens units on the first compound eye lens 310 and the second compound eye lens 320 can be set to a sufficient number to ensure the beam homogenization effect, thereby ensuring the light output effect of the light source system.

[0042] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 7As shown, the off-axis rotation mechanism 500 includes a first deflection connector 510 and a second deflection connector 520. The first deflection connector 510 includes a first rotating shaft 501 and a second rotating shaft 502 arranged parallel but not coaxially. The first rotating shaft 501 is rotatably connected to the collimating lens bracket 210, and the second rotating shaft 502 is rotatably connected to the support frame assembly 600. The second deflection connector 520 includes a third rotating shaft 503 and a fourth rotating shaft 504 arranged parallel but not coaxially. The third rotating shaft 503 is rotatably connected to the collimating lens bracket 210, and the fourth rotating shaft 504 is rotatably connected to the support frame assembly 600. Since the first rotating shaft 501 is rotatably connected to the collimating lens bracket 210, and the second rotating shaft 502 is rotatably connected to the support frame assembly 600, and the first rotating shaft 501 and the second rotating shaft 502 are not coaxial, when the second rotating shaft 502 rotates, it will drive the first rotating shaft 502 to rotate, thereby causing the collimating lens assembly 200 to rotate eccentrically relative to the second rotating shaft 502, thus realizing the rotational movement of the collimating lens assembly 200. The second deflection connector can make the rotational movement of the collimating lens assembly 200 smoother. Further, in this embodiment, there are two second deflection connectors 520. In other embodiments, there may be one, three, or more second deflection connectors 520. In particular, in this embodiment, the light-emitting body group 120 includes three types of light-emitting bodies, namely, a first light-emitting body 101, a second light-emitting body 102, and a third light-emitting body 103. The three types of light-emitting bodies are arranged in a circular arc, and the distance between the first rotating shaft 501 and the second rotating shaft 502 is equal to the radius of the arc. More specifically, in this embodiment, the three light emitters are arranged in an equilateral triangle, that is, the three light emitters are evenly distributed on a circle. If the three light emitters are arranged in a straight line, and the distance between the center points of two adjacent light emitters is d1, and the collimating lens assembly moves in a straight line, with the initial position aligned with the middle light emitter, then when the collimating lens assembly needs to align with the light emitters on both sides, the distance the collimating lens assembly needs to move relative to the initial position is d1. Using the technical solution of this embodiment, if the distance between the center points of two adjacent light emitters is also d1, and the initial position of the collimating lens assembly is aligned with the center of the circle containing the three light emitters, then relative to the initial position, when the collimating lens assembly needs to align with any one light emitter, the distance the collimating lens assembly needs to move is approximately 0.577d1. It can be seen that the maximum distance of the collimating lens assembly's offset relative to the initial position is smaller. Therefore, compared with the straight-line arrangement, the maximum offset of the optical axis of the collimating lens assembly relative to the optical axis of the converging lens assembly is smaller, resulting in less optical expansion loss and higher light extraction efficiency of the light source system.

[0043] Furthermore, if Figure 2 , Figure 3 , Figure 6 , Figure 7As shown, the support frame assembly 600 includes a first support frame 610 with a first through hole 611 and a second support frame 620 with a second through hole 621. A second rotating shaft 502 is inserted into the first through hole 611, and a fourth rotating shaft 504 is inserted into the second through hole 621. In this embodiment, the first support frame 610 and the second support frame 620 are independent structures. In other embodiments, the first support frame 610 and the second support frame 620 can also be integrally formed, for example, the first support frame 610 and the second support frame 620 are both part of a larger support frame. The support frame assembly 600 is disposed on the substrate 110.

[0044] Preferably, bearings are also provided in the first through hole 611 and the second through hole 621, and the second rotating shaft 502 and the fourth rotating shaft 504 are both inserted into the bearings. The bearing design enables smoother rotational movement.

[0045] Furthermore, the drive assembly 700 includes a drive member 710 and a transmission member 720 connected to the output end of the drive member 710, and the first deflection connector 510 is connected to the transmission member 720. More specifically, in this embodiment, the output end is a worm gear.

[0046] Furthermore, the transmission component 720 is a worm gear, and the second shaft 502 of the first deflection connector 510 is located at the center of the worm gear, with the worm gear shaft coinciding with the second shaft 502. When the worm gear rotates, it drives the worm gear to rotate, which in turn causes the second shaft 502 to rotate, thereby driving the first shaft 501 to rotate, thus realizing the rotational movement of the collimating lens bracket 210.

[0047] Furthermore, in this embodiment, a mounting bracket 730 is also provided for supporting and installing the drive component 710.

[0048] Furthermore, a locking interface 721 is provided at the center of the worm gear, and the first off-axis connector 510 includes a locking post 5021 that matches the locking interface 721. When the worm gear rotates, the locking post 5021 rotates accordingly. More specifically, in this embodiment, the locking post 5021 is part of the second rotating shaft 502 and is located at the end away from the first rotating shaft 501. When the worm gear drives the locking post 5021 to rotate, it will drive the first off-axis connector 510 to rotate, thereby driving the collimating lens bracket 210 to rotate. More specifically, in this embodiment, the locking interface 721 is set as a chamfered through hole or a chamfered slot, and correspondingly, the cross-section of the locking post 5021 is a chamfer that matches the locking interface 721.

[0049] Furthermore, such as Figures 1 to 3 , Figure 9As shown, the light source system further includes a limiting component 800 for limiting the rotation of the collimating lens assembly 200. Further, in this embodiment, the limiting component 800 includes three ball-head plungers 810 disposed on the support frame assembly 600 and positioning holes 820 on the collimating lens bracket 210 that match the ball-head plungers 810; the number of ball-head plungers 810 is the same as the number of light-emitting elements in the same group of light-emitting elements, and the positioning holes 820 are located on the movement trajectory of the ball-head plungers 810. When the ball-head plungers 810 are respectively engaged in different positioning holes 820, the lens units on the collimating lens assembly 200 are respectively aligned with different light-emitting elements. In other embodiments, the ball-head plungers 810 may be disposed on the collimating lens bracket 210, and the positioning holes 820 may be disposed on the support frame assembly 600. The ball-head plungers can be commercially available conventional structures, which will not be described in detail here.

[0050] Furthermore, if Figure 8 As shown, the collimating lens holder 210 has a plurality of small through holes arranged in an array. The lens unit includes a first lens unit 221 and a second lens unit 222. The first lens unit 221 is composed of a plurality of first microlenses arranged in an array, and the first microlenses are disposed in the small through holes. The second lens unit 222 is a lens array composed of a plurality of second microlenses, which can be obtained by integral molding. The first microlenses and the second microlenses are arranged in a one-to-one correspondence.

[0051] Furthermore, in this embodiment, the placement angles of the second light-emitting elements in different light-emitting element groups follow an arithmetic progression. For example... Figure 4 , Figure 5 As shown, in this embodiment, the second light-emitting element 102 of the second light-emitting element group 122 rotates by an angle of 120° relative to the second light-emitting element 102 of the first light-emitting element group 121, and the second light-emitting element 102 of the third light-emitting element group 103 rotates by an angle of 240° relative to the second light-emitting element 102 of the first light-emitting element group 121. In other embodiments, if there are four types of light-emitting element groups, the second light-emitting element in the second light-emitting element group rotates by an angle of 90° relative to the second light-emitting element in the first light-emitting element group, the second light-emitting element in the third light-emitting element group rotates by an angle of 180° relative to the second light-emitting element in the first light-emitting element group, the second light-emitting element in the fourth light-emitting element group rotates by an angle of 270° relative to the second light-emitting element in the first light-emitting element group, and so on.

[0052] Furthermore, if Figure 4As shown, in this embodiment, three groups of light emitters 120 are arranged on the substrate in a concentric polygonal ring array or a concentric circular ring array. The first light emitter group 121, the second light emitter group 122, and the third light emitter group 123 are sequentially interspersed in each ring in the same order. This design can make the uniformity of the final emitted light spot on the focal plane better.

[0053] Furthermore, in this embodiment, the second light-emitting element 102 includes green LEDs, red LEDs, blue LEDs, and lemon-green LEDs. In other embodiments, the second light-emitting element 102 may also be other multi-color LEDs or LEDs with different optical parameters.

[0054] Furthermore, in this embodiment, the first light-emitting element 101 and the third light-emitting element 103 can be either high color rendering index (CRI) LEDs or high brightness LEDs. In other embodiments, the first light-emitting element 101 and the third light-emitting element 103 can also be LEDs with different optical parameters.
