[0002] At present, the optical structure of the light source of high-power stage lights mainly includes an LED array, a collimating lens, a homogenizing lens, and a converging lens arranged in sequence in the light emitting direction of the LED array. The collimating lens is used to collimate the light emitted by the LED light source with a Lambertian distribution into nearly parallel light, and the homogenizing lens homogenizes the nearly parallel light to obtain a more homogenized light. The converging lens converges the homogenized light to a preset plane to form the desired light spot.

[0044] Example 1

[0045] like Figure 1 , Figure 2 As shown, a multifunctional light source system comprises a light source substrate 1, a plurality of LED light emitters 2 arranged in an array and emitting light, arranged in sequence along the light emitting direction of the LED light emitter group 2, a collimating lens assembly 3 for gathering and / or collimating the light, a light homogenizing assembly 4 for homogenizing the light, and a converging lens assembly 5 for converging the light to a preset plane to form a light spot, wherein the collimating lens assembly 3 is provided with a plurality of lens units, the LED light emitter group 2 comprises at least two different first LED light emitters 211 and second LED light emitters 221, and the plurality of first LED light emitters 211 and the plurality of second LED light emitters 221 respectively constitute a first LED light array 21 and a second LED light array 22;

[0046] The light homogenizing component 4 at least includes a first light homogenizing element and a second light homogenizing element, wherein the first light homogenizing element is used to make the illumination of the light spot present a Gaussian-like distribution, and the second light homogenizing element is used to make the illumination of the light spot uniform;

[0047] The multifunctional light source system also includes a first adjustment component and a second adjustment component, wherein the first adjustment component is used to adjust the collimating lens component 3 so that the lens unit can be optionally aligned with the first LED light array 21 or the second LED light array 22, and the second adjustment component is used to adjust the light homogenizing component 4 so that the first light homogenizing component or the second light homogenizing component can be selectively aligned with the area where the LED light-emitting body group is located.

[0048] The light source substrate 1 of the present application is used to install a plurality of LED light-emitting body groups 2 arranged in an array, wherein the LED light-emitting body group 2 includes at least two different first LED light-emitting bodies 211 and second LED light-emitting bodies 221, wherein the plurality of first LED light-emitting bodies 211 and the plurality of second LED light-emitting bodies 221 respectively constitute a first LED light-emitting array 21 and a second LED light-emitting array 22, wherein the first adjustment component adjusts the collimating lens component 3 so that the lens unit can be optionally aligned with the first LED light-emitting array 21 or the second LED light-emitting array 22, and then the collimating lens component 3 can gather and / or collimate the light of at least two LED light-emitting bodies to obtain at least two light with different light effects, and the light-homogenizing component 4 includes at least a first light-homogenizing member and a second light-homogenizing member, wherein the first light-homogenizing member enables the light of at least two LED light-emitting bodies to be converged by the converging lens component 4. After the component 5 acts, the illumination of the light spot formed on the preset plane presents a quasi-Gaussian distribution, the second light homogenizing component makes the illumination of the light spot on the preset plane uniform (the illumination uniformity mentioned in this application refers to the illumination presenting a quasi-flat-top distribution), the second adjustment component adjusts the light homogenizing component 4 so that the first light homogenizing component or the second light homogenizing component can be selectively aligned with the first LED light-emitting array 21 or the second LED light-emitting array 22, then the light of the first LED light-emitting array 21 can be further homogenized into two light rays with different effects, and the light of the second LED light-emitting array 22 can also be homogenized into two light rays with different effects, so that at least four different light spots can be emitted through the converging lens component 5. The technical solution of this embodiment can achieve at least four different light-emitting effects through a light source substrate 1, which greatly enriches the function of the light source system.

[0049] Furthermore, the first adjustment assembly includes a first driving member for driving the collimating lens assembly 3 to move, a first guiding structure for guiding the movement of the collimating lens assembly 3, and a sliding member connected to the collimating lens assembly 3 and slidably connected to the first guiding structure. Figure 1 , Figure 3 , 4As shown, in this embodiment, the first guiding structure includes a first linear optical axis 62 and a second linear optical axis 63 arranged on two opposite sides of the collimating lens assembly 3, a first supporting member 661 and a second supporting member 662 for supporting the first linear optical axis 62 and the second linear optical axis 63, respectively, and the sliding member includes a first sliding member and a second sliding member respectively connected to the first linear optical axis 62 and the second linear optical axis 63 in a sliding manner.

[0050] Furthermore, if Figure 1 , Figure 5 , Figure 6 As shown, the collimating lens assembly 3 includes a collimating lens bracket 32 ​​for mounting the plurality of lens units, one side of the collimating lens bracket 32 ​​is provided with a first mounting boss 651 and a second mounting boss 652 for mounting the two ends of the first linear optical axis 62, respectively, and the other side of the collimating lens bracket 32 ​​is provided with a third mounting boss 653 and a fourth mounting boss 654 for mounting the two ends of the second linear optical axis 63, respectively, and the first mounting boss 651, the second mounting boss 652, the third mounting boss 653, and the fourth mounting boss 654 are respectively provided with a first collimating lens bracket 32. The first sliding member comprises a first sleeve 641 and a second sleeve 642 fixedly arranged in the first and second accommodating grooves 6511 and 6521, respectively, and the second sliding member comprises a third sleeve 643 and a fourth sleeve 644 fixedly arranged in the third and fourth accommodating grooves 6531 and 6541, respectively. The first linear optical axis 62 is passed through the first sleeve 641 and the second sleeve 642, and the second linear optical axis 63 is passed through the third sleeve 643 and the fourth sleeve 644. In this embodiment, the first mounting boss 651, the second mounting boss 652, the third mounting boss 653, the fourth mounting boss 654 and the collimating lens bracket 32 ​​are integrally formed. In other embodiments, each mounting boss may also be a separate structure fixed to the collimating lens bracket 32 ​​by screws or other means. Since each sleeve is fixedly arranged in the receiving groove of each mounting boss, each sleeve is slidably connected to the optical axis, and the directional movement of the collimating lens bracket on the optical axis can be achieved by sliding the sleeve on the optical axis.

[0051] In this embodiment, the lens unit includes a first lens unit 311 and a second lens unit 312. The first lens unit 311 is composed of a plurality of first small lenses arranged in an array. The collimating lens holder 32 is provided with a plurality of through holes for mounting the first small lenses, and the first small lenses are mounted in the through holes. The second lens unit 312 is composed of a plurality of second small lenses, and the plurality of second small lenses are integrally formed into an array lens. The optical centers of the first small lenses and the second small lenses correspond one to one.

[0052] Furthermore, if Figure 7 , Figure 8 As shown, the first support member 661 and the second support member 662 are metal members provided with a linear mounting groove 6611, and the linear mounting groove 6611 matches the first linear optical axis 62 and the second linear optical axis 63, and the first support member 661 and the second support member 662 are respectively arranged in the middle of the first linear optical axis 62 and the second linear optical axis 63. In this embodiment, the first support member 661 and the second support member 662 have the same structure and are symmetrically arranged on both sides of the collimating lens bracket 32. The design of the linear mounting groove 6611 can, on the one hand, provide good support for the linear optical axis, and on the other hand, can ensure that the linear optical axis is not easily deflected, thereby better ensuring the adjustment accuracy of the first adjustment component. The first support member 661 and the second support member 662 are arranged in the middle of the optical axis, which can better ensure the balance of the collimating lens component 3 and improve the adjustment accuracy. Furthermore, a first fastener for fastening the first linear optical axis 62 and the first support 661 is provided above the first linear optical axis 62, and a second fastener for fastening the second linear optical axis 63 and the second support 662 is provided above the second linear optical axis 63. Specifically, the first fastener and the second fastener are both screws 663, and the first support 661 and the second support 662 are provided with screw holes 6612 for installing the screws 663.

[0053] Further, in the present embodiment, the maximum strokes of the first mounting boss 651 and the second mounting boss 652 relative to the first support member 661, and the maximum strokes of the third mounting boss 653 and the fourth mounting boss 654 relative to the second support member 662, are equal to the distance between the optical centers of the first LED light emitter 211 and the second LED light emitter 221. The distance between the optical centers of the first LED light emitter 211 and the second LED light emitter 221 mentioned here refers to the distance from the center point of the first LED light emitter 211 to the center point of the second LED light emitter 221. Specifically, the positioning of the moving positions of the first mounting boss 651, the second mounting boss 652, the third mounting boss 653, and the fourth mounting boss 654 is achieved by the first support member 661 and the second support member 662. In order to facilitate a clearer understanding of the working process of movement and positioning, the movement of one side of the collimating lens assembly 3 is taken as an example for explanation: as shown in 6, Fig. 9As shown, the first support member 661 is arranged in the middle of the first linear optical axis 62 and is fixed relative to the first linear optical axis 62. The two ends of the first linear optical axis 62 are slidably connected with the first sleeve 641 and the second sleeve 642. The first sleeve 641 and the second sleeve 642 are arranged in the first mounting groove 6511 and the second mounting groove 6521 of the first mounting boss 651 and the second mounting boss 652. When the first driving member drives the collimating lens bracket 32 ​​to move in the direction B, the first sleeve 641 and the second sleeve 642 move along the first linear optical axis 62 to the direction B. When the first mounting boss 651 collides with the first support 661, the sleeve can no longer move, that is, the collimating lens bracket 32 ​​has reached the preset position and is aligned with the desired light-emitting body array; when the first driving mechanism drives the collimating lens bracket 32 ​​to move in the A direction, the first sleeve 641 and the second sleeve 642 move in the A direction along the first linear optical axis 62, and when the second mounting boss 652 collides with the first support 661, the sleeve can no longer move, that is, the collimating lens bracket 32 ​​has reached the preset position and is aligned with another light-emitting body array. Similarly, the movement of the other side of the collimating lens assembly 3 is the same, thereby realizing the directional movement and movement limit of the collimating lens assembly 3.

[0054] Furthermore, the first driving member is two solenoid valves 61 arranged on two opposite sides of the collimating lens assembly 3. More specifically, the two solenoid valves 61 are symmetrically arranged along the collimating lens assembly 3. Such a design can make the driving force on the collimating lens assembly 3 more balanced. Furthermore, the two ends of the collimating lens bracket 32 ​​close to the two solenoid valves 61 are provided with connecting parts 321 matching the iron core 611 of the solenoid valves, and the connecting parts 321 are clamped on the iron core 611. In this embodiment, the connecting part 321 is a part of the collimating lens bracket 32, that is, the collimating lens bracket 32 ​​and the connecting part 321 are integrally formed.

[0055] The specific working principle of the adjustment performed by the first adjustment component is as follows: when the solenoid valve 61 on one side of the collimating lens bracket 32 ​​is energized, the iron core of the solenoid valve 61 retracts to pull the collimating lens bracket 32. Since the first sleeve 641, the second sleeve 642, the third sleeve 643, and the fourth sleeve 644 are fixedly arranged in four grooves on both sides of the collimating lens bracket, and the first straight optical axis 62 is penetrated in the first sleeve 641 and the second sleeve 642, and the second straight optical axis 63 is penetrated in the third sleeve 643 and the fourth sleeve 644, when the solenoid valve 61 pulls the collimating lens bracket 3, the collimating lens bracket 32 ​​can slide along the first straight optical axis 62 and the second straight optical axis 63. Compared with the design in which only one sleeve is arranged on each side, the design in which two sleeves are arranged on both sides and the sleeves are located at the two ends of the straight optical axis can make the movement of the collimating lens bracket 32 ​​more accurate, the collimating lens bracket 32 ​​is not easy to deflect, and the sleeve is low in price, which can reduce costs. When the first mounting boss 651 of the collimating lens bracket 32 ​​collides with the first support member 661 and the third mounting boss 653 collides with the second support member 662, the collimating lens assembly 3 is aligned with one of the LED light-emitting arrays; when the second mounting boss 652 of the collimating lens bracket 32 ​​collides with the first support member 661 and the fourth mounting boss 654 collides with the second support member 662, the collimating lens assembly 3 is aligned with another LED light-emitting array.

[0056] Furthermore, the light homogenizing component 4 further includes a light homogenizing bracket 43, the first light homogenizing member is a light homogenizing diffuser 41, the second light homogenizing member is a fly-eye lens pair 42, and the light homogenizing diffuser 41 and the fly-eye lens pair 42 are both arranged on the light homogenizing bracket 43. In this embodiment, the fly-eye lens pair 42 is a double-piece fly-eye lens, and in other embodiments, the fly-eye lens pair 42 may also be a single-piece structure with the same structure on both sides.

[0057] Furthermore, the second adjustment component includes a main adjustment mechanism located on one side of the light homogenizing component 4, and the main adjustment mechanism includes a second driving member for driving the light homogenizing component 4 to move, a second guide structure for guiding the moving direction of the light homogenizing component 4, and a first connecting member 713 connected to the light homogenizing bracket and the second driving member and movably connected to the second guide structure.

[0058] Furthermore, if Figure 3 , Figure 4 as well as Figure 10-15As shown, the second guide structure includes a fixed seat and a third linear optical axis 711 disposed on the fixed seat, the third linear optical axis 711 passes through the first connecting member 713 and is slidably connected to the first connecting member 713, and the second driving member is a screw motor 712, the screw of the screw motor 712 passes through the first connecting member 713 and is threadedly connected to the first connecting member 713. Further, the number of the third linear optical axes 711 is two, and the two third linear optical axes 711 are symmetrically arranged relative to the screw motor 712. More specifically, as Fig.15 As shown, the main adjustment mechanism is a motor slide group 71.

[0059] Furthermore, the second adjustment component also includes an auxiliary adjustment mechanism 72 located on the other side of the light homogenizing component, the auxiliary adjustment mechanism 72 includes a third guide structure and a second connecting member 722 slidably connected to the third guide structure, and the third guide structure includes a fourth linear optical axis 721. In this embodiment, the auxiliary adjustment mechanism 72 located on the other side of the light homogenizing component 4 is configured to be different from the main adjustment mechanism, which can save costs on the one hand, and on the other hand, if both sides are configured to be motor slide groups 71, if the motor slide groups 71 are not completely synchronized, it will cause unsmooth movement.

[0060] Furthermore, the multifunctional light source system is further provided with a housing 9, the first connecting member 713 and the third guiding structure (i.e., the fourth linear optical axis 721) are fixedly connected to the light homogenizing bracket 43, and the second guiding structure and the second connecting member 722 are fixedly connected to the housing 9. Figure 4 As shown, the fourth linear optical axis 721 is disposed through the second connecting member 722, the second connecting member 722 is provided with a through hole, a bearing 723 is further disposed in the through hole, and the fourth linear optical axis 721 is disposed through the bearing 723. Fig.14As shown, the second connecting member 722 is a metal block with a through hole. Compared with the method of fixing the fourth linear optical axis 721 on the housing 9 and setting the second connecting member 722 to be fixedly connected to the light homogenizing bracket 43, in this embodiment, the fourth linear optical axis 721 is set to be fixedly connected to the light homogenizing bracket 43, and the second connecting member 722 is set to be fixed on the housing 9. On the one hand, the driving load of the screw motor 713 of the motor slide group 71 can be reduced, because the fourth linear optical axis 721 is lighter than the bearing 723 and the second connecting member 722, which can make the structure of the components to be driven by the motor slide group 71 lighter; on the other hand, it can save material costs and installation man-hours, and the cost is lower; on the other hand, since the relative positions of the first connecting member 713 and the second connecting member 722 are changed during the movement of the light homogenizing component 4, the connecting line between the two is not perpendicular to the moving direction of the first connecting member 713, which can ensure that the light homogenizing bracket 43 basically does not deflect up and down in the vertical direction, and only a very small amount of left and right deflection may occur in the same horizontal plane, and the accuracy is higher.

[0061] Furthermore, if Fig.15 , Fig.16 , Fig.17 As shown, the second adjustment component 7 also includes a micro switch 8 for limiting the extreme movement position of the light homogenizing component 4. More specifically, the micro switch 8 includes a first micro switch 81 and a second micro switch 82, which have the same structure and are arranged at both ends of the auxiliary adjustment mechanism 72. Furthermore, the first microswitch 81, the second microswitch 82, and the lead screw motor 712 are all connected to the external driving board. When the light homogenizing bracket 43 touches the first microswitch 81, the first microswitch 81 is switched from a high level mode to a low level mode, and the signal is immediately sent to the driving board.

Specifically, the light source substrate 1 and the outer shell 9 are locked to the mounting bracket 10 by screws, thereby realizing a fixed connection between the outer shell 9 and the light source substrate 1.

[0064] In this embodiment, the LED light-emitting body group 2 on the light source substrate 1 is provided with two kinds of LED light-emitting bodies as an example, and the LED light-emitting body group 2 is composed of a first LED light-emitting body 211 and a second LED light-emitting body 221. A plurality of first LED light-emitting bodies 211 constitute a first LED light-emitting array 21, and a plurality of second LED light-emitting bodies 221 constitute a second LED light-emitting array 22.

At this time, the lens unit is aligned with the first LED light emitter 211, and the fly-eye lens pair 42 on the light homogenizing assembly is aligned with the first LED light array 21 through the second adjustment assembly. Fig.18 As shown, when the light effect of the first LED light array 21 is desired and a light spot with a Gaussian-like illumination distribution is obtained (recorded as the second functional mode), only the first LED light emitter 211 is lit, and the collimating lens assembly 3 is aligned with the first LED light array 21 through the first adjustment assembly, and the uniform light diffuser 41 on the uniform light assembly is aligned with the first LED light array 21 through the second adjustment assembly. Fig.19 As shown, when the light effect of the second LED light array 22 is desired and a light spot with uniform illumination is obtained (recorded as the third functional mode), only the second LED light emitter 221 is lit, and the collimating lens assembly 3 is aligned with the second LED light array 22 through the first adjustment assembly. At this time, the lens unit is aligned with the second LED light emitter 221, and the fly-eye lens pair 42 on the light homogenizing assembly is aligned with the second LED light array 22 through the second adjustment assembly. Fig. 20 As shown, when the light effect of the second LED light array 22 is desired and a light spot with a Gaussian-like illumination distribution is obtained (recorded as the fourth functional mode), only the second LED light emitter 221 is lit, and the collimating lens assembly 3 is aligned with the second LED light array 22 through the first adjustment component, and the uniform light diffuser 41 on the uniform light assembly is aligned with the second LED light array 22 through the second adjustment component, thereby achieving switching between different functions. In order to more intuitively see the relative positions of the collimating lens assembly 3, the uniform light assembly 4 and the LED array, the fourth functional mode is shown in FIG. Figure 17-Figure 18The light homogenizing assembly only shows the light homogenizing lens bracket 43, but does not show the light homogenizing diffuser 41 and the fly-eye lens pair 42. In other embodiments, the LED light emitting body group 2 may further include more types of LED light emitting bodies, and the light homogenizing assembly 4 may further include more types of light homogenizing members or part of the structure of the light homogenizing assembly 4 may be a hollow design, thereby achieving more abundant functions.
