TECHNICAL FIELD
[0001] The present application relates to the technical field of stage light, more particularly, to a light path deflectable lamp. BACKGROUND
[0002] Due to the straight propagation characteristics of light, in order to ensure the precise controllability of light efficiency, a light axis is generally preset for the stage light, all the optical lens axes inside are coincident with the light axis, and the light emitted by the light source is always shot along the light axis to the light collecting mirror located at the light outlet of the lamp. Various effect components arranged on the light path only interfere with the rendering or cutting / shading of the fixed light beam, although the light efficiency is precisely controllable, it is difficult to lack of creativity and the dynamic change effect is limited. SUMMARY
[0003] The present application provides a light path deflectable lamp to overcome at least one of the above-mentioned defects of the prior art, which deflects the light away from the original light path by a light guide element to generate a special light effect.
[0004] To solve the above technical problems, the technical solution adopted by the present application is as follows: a light path deflectable lamp, comprising a lamp head, a light source located in the lamp head, a light guide element located on the light path of the light source, and a light collecting mirror located at the light outlet of the lamp head, further comprising a movement driver for driving the light guide element to cut into / cut out the light path of the light source, when the light guide element is located outside the light path, the light source emits a first light beam to irradiate a first position of the light collecting mirror, the central axis of the first light beam is perpendicular to the plane where the light collecting mirror is located, when the light guide element is located in the light path, the first light beam irradiates the light-in end of the light guide element, the light guide element emits a second light beam from the light-out end and irradiates a second position of the light collecting mirror.
[0005] The light path deflectable lamp, when the light guide element is located outside the light path, the first light beam emitted by the light source irradiates the first position of the light collecting mirror, and a predetermined light spot is projected at a predetermined position on the projection surface; when the light guide element is located in the light path, the light guide element deflects the irradiation of the first light beam, then emits a second light beam from the light-out end and irradiates the second position of the light collecting mirror, and is emitted from the light outlet, so that a deflected light spot is projected at a deflected position on the projection surface, finally, the light spot position is moved even the light spot shape is deformed (the curvature is different at different distances from the optical axis of the light collecting mirror), and the effect is more rich.
[0006] Further, a light receiving element is further included for receiving light from the light source, and the light receiving element directly guides the light from the light source to the light receiving mirror or to the light receiving mirror through the light guide element. The light receiving element can converge the light from the light source to avoid divergence and improve the light utilization rate of the light source.
[0007] Further, the light receiving element is a light guide body. The light guide body receives light from the light source and mixes the light from the light source to improve the uniformity of the first light beam and guide the first light beam to the corresponding optical element.
[0008] Further, the light-in end of the light guide element is adjacent to the light-out surface of the light receiving element to better receive the light emitted by the light receiving element and avoid light overflow and energy waste.
[0009] Further, the light guide element is a light guide body. The light guide body generally uses a solid glass rod for total internal reflection or a hollow cylinder with a mirror surface on the inner wall for light guiding. The light guiding efficiency is high, and the problems of aberration and dispersion can be avoided. Moreover, the length direction of the light guide element is directly used to control the direction of the second light beam to the second position on the light receiving mirror, and the direction control is accurate.
[0010] Further, the end surfaces of the light-in end and the light-out end of the light guide element are parallel. Thus, the second light beam is parallel to the first light beam, which means that the first light beam is only shifted without rotation, reducing the distortion of the deflected light spot.
[0011] Further, the light guide element is a slanting prism. The side walls of the prism can mix the internal light, and the side walls are parallel to each other, which is easy to process.
[0012] Further, the light guide element is elongated from the light-in end to the light-out end, and the angle between the optical axis and the first light beam is greater than 0 degrees and less than 90 degrees. This allows the first light beam to smoothly enter the light guide element with less light loss.
[0013] Further, the first position is the optical axis of the light receiving mirror. The first light beam is irradiated to the optical axis of the light receiving mirror, and the light spot shape is not easily distorted, thereby forming a predetermined light spot.
[0014] Further, a rotation drive is further included for driving the rotation of the light guide element. When the light guide element rotates in the light path, the light-in end of the light guide element always receives the first light beam. That is, the light-out end of the light guide element always emits the second light beam, and the deflected light spot does not suddenly disappear.
[0015] Further, the second light beam is directed to different positions of the same light receiving mirror when the light guide element rotates in the light path. Thus, the deflected light spot can move continuously, and even continuously deform (when the curvatures of different positions are different), and the light effect is more abundant.
[0016] Further, the first position is the optical center of the light receiving mirror, and the second light beam is directed to a circular ring with the optical center of the light receiving mirror as the center when the light guide element rotates in the light path. Thus, the deflected light spot can move in a circular motion around the position of the preset light spot on the projection surface.
[0017] Further, the light source is a plurality of light sources, each corresponding to a light receiving mirror, and at least one of the light sources is provided with a light guide element that cuts in and out of the light path. Multiple light sources can work together to produce light effects, or some of the light sources can be configured with the light guide element to deflect their light paths and produce special light effects.
[0018] Further, multiple light sources are provided with light guide elements that cut in and out of the light path, and each light guide element is provided with a rotation drive to drive its rotation. The movement drive and / or the rotation drive are independent of each other. Each movement drive is independent of each other, so that the light guide element can be selected according to the needs of which light source to configure. Each rotation drive is independent of each other, so that the light guide element can be rotated according to the needs of which light source to configure. The degree of freedom is high, and the light effect is complex.
[0019] Further, only the light sources located at the outermost periphery are provided with light guide elements that cut in and out of the light path. By utilizing the peripheral space to set the light guide elements that cut in and out of the light path, the function of light path deflection can be added without changing the existing lamp as much as possible.
[0020] Further, it also includes a focusing drive to drive the light receiving mirror. By driving the light receiving mirror to move closer to or farther away from the light source, the light spot can be zoomed. In combination with the deflection of the light path by the light guide element and the deformation of the light spot, a variety of effects can be achieved. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION
[0028] The drawings are only used for illustrative description and cannot be understood as a limitation of the present application; in order to better illustrate the present embodiment, some components in the drawings are omitted, enlarged or reduced and do not represent the actual product size; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings can be omitted. The positional relationship described in the drawings is only used for illustrative description and cannot be understood as a limitation of the present application.
[0029] As Figures 1 to 3 , the present application provides a light path deflectable lamp, comprising a lamp holder 100, a light source 200 located in the lamp holder 100, a light guide element 300 located in the light path of the light source 200, and a light collecting mirror 400 located at the light outlet 110 of the lamp holder 100, further comprising a movement drive 500 for driving the light guide element 300 to cut into / out of the light path of the light source 200, when the light guide element 300 is located outside the light path, the light source 200 emits a first light beam 210 to irradiate a first position of the light collecting mirror 400, the central axis of the first light beam 210 is perpendicular to the plane where the light collecting mirror 400 is located, when the light guide element 300 is located in the light path, the first light beam 210 irradiates to the light inlet end 310 of the light guide element 300, the light guide element 300 emits a second light beam 220 from the light outlet end 320 and irradiates to a second position of the light collecting mirror 400.
[0030] The light path of the lamp can be deflected. When the light guide element 300 is located outside the light path, the first light beam 210 emitted by the light source 200 is irradiated to the first position of the light receiving mirror 400, and a predetermined light spot is projected on the predetermined position of the projection surface. When the light guide element 300 is located in the light path, the light guide element 300 deflects the irradiation of the first light beam 210, and then the second light beam 220 is emitted from the light emitting end 320 and irradiated to the second position of the light receiving mirror 400, and is emitted from the light emitting port 110, so that a deflected light spot is projected on the deflected position of the projection surface. Finally, the light spot position is moved, and even the light spot shape can be deformed (the light receiving mirror 400 has different curvatures at different distances from the optical axis 410), and the effect is more rich. The central axis of the first light beam 210 is perpendicular to the plane in which the light receiving mirror 400 is located. When the light guide element 300 is located outside the light path, the light receiving mirror 400 can reduce the reflection of the first light beam 210.
[0031] It should be noted that the light guide element 300 guides the first light beam 210 to be irradiated to the first position of the light receiving mirror 400, and is deflected to the second light beam 220 and irradiated to the second position of the light receiving mirror 400, which means that the first light beam 210 is deflected as a whole, and the central axis of the light path is deflected. It is not ordinary light splitting in which the central axis of the light path remains unchanged.
[0032] The second light beam 220 can be obtained by offsetting (the light beams are parallel before and after offsetting) the first light beam 210 through the light guide element 300, or can be obtained by rotating (the light beams form an angle before and after rotating) the first light beam 210 through the light guide element 300. The light emitting direction of the second light beam 220 is always perpendicular to the end face of the light emitting end 320 of the light guide element 300. By adjusting the direction of the end face of the light emitting end 320 of the light guide element 300, the light emitting direction of the second light beam 220 can be changed.
[0033] Preferably, the middle part of the light receiving mirror 400 except the edge position is rotationally symmetric about the optical axis 410 thereof.
[0034] In the preferred embodiment of the application, the light receiving element 230 for receiving light of the light source 200 is further included. The light receiving element 230 directly guides the light of the light source 200 to the light receiving mirror 400 or guides the light of the light source 200 to the light receiving mirror 400 through the light guide element 300. The light receiving element 230 can converge the light rays of the light source 200 to avoid divergence and improve the light utilization rate of the light source 200.
[0035] The light receiving element 230 can be a reflecting cup, a condenser, a TIR lens, or a light guide body.
[0036] In the preferred embodiment of the present application, the light collecting element 230 is a light guide. The light guide generally uses a solid glass rod total internal reflection or hollow tube with internal wall mirror to guide light. The light guide collects light from the light source 200 and mixes the light from the light source 200 to improve the uniformity of the first light beam 210, and guides the first light beam 210 to the corresponding optical element.
[0037] Preferably, the light exit surface of the light guide is provided with a light uniformization element (such as a diffuser sheet, compound eye), or the light exit surface is directly frosted or microstructured.
[0038] In the preferred embodiment of the present application, the light entrance end 310 of the light guide element 300 is immediately adjacent to the light exit surface of the light collecting element 230. This better receives the light emitted by the light collecting element 230 and avoids light overflow and energy waste.
[0039] Preferably, the gap between the light entrance end 310 of the light guide element 300 and the light exit surface of the light collecting element 230 is less than 1 mm, and is as close as possible.
[0040] In this embodiment, the light entrance end 310 of the light guide element 300 is larger than the light exit surface of the light collecting element 230 and completely covers the light exit surface of the light collecting element 230 to reduce light leakage.
[0041] In the preferred embodiment of the present application, the light guide element 300 is a light guide. The light guide generally uses a solid glass rod total internal reflection or hollow tube with internal wall mirror to guide light, which has high light guide efficiency and can avoid aberration and dispersion problems. Moreover, the length direction of the light guide element 300 is directly used to control the direction of the second light beam 220 to the second position on the light collecting mirror 400, which is accurate.
[0042] The cross-sectional shape of the second light beam 220 can also be controlled by controlling the shape of the light exit end 320 of the light guide element 300 to change the basic shape of the deflected light spot. In this embodiment, the light exit end 320 of the light guide element 300 is rectangular.
[0043] In the preferred embodiment of the present application, the end faces of the light entrance end 310 and the light exit end 320 of the light guide element 300 are parallel. This makes the second light beam 220 parallel to the first light beam 210, i.e. the first light beam 210 is only shifted without being rotated, which reduces the distortion of the deflected light spot.
[0044] Preferably, the end surface of the light-in end 310 and the light-out end 320 are both perpendicular to the central axis of the first light beam 210, i.e. parallel to the plane where the light-receiving mirror 400 is located, which can ensure that the light-in end 310 receives more first light beams 210 into the light guide element 300 and reduce the reflection of the second light beam 220 by the light-receiving mirror 400.
[0045] In the preferred embodiment of the present application, the light guide element 300 is a prismatic oblique prism. The side walls of the prism can mix the internal light, and the side walls are parallel to each other, which is easy to process.
[0046] Preferably, the light guide element 300 is a prismatic oblique prism with four parallel side walls of the same width. In other embodiments, the prismatic oblique prism can have more parallel side walls, and the widths of the side walls can be different from each other to change the light mixing effect.
[0047] In the preferred embodiment of the present application, the light guide element 300 is elongated from the light-in end 310 to the light-out end 320, and the angle between the optical axis 330 and the first light beam 210 is greater than 0 degrees and less than 90 degrees. The optical axis 330 of the elongated light guide element 300 is consistent with the length direction of the light guide element 300, and the angle between the optical axis 330 of the light guide element 300 and the first light beam 210 is an acute angle, which can reduce the loss and leakage of light in the light guide element 300.
[0048] Preferably, the light guide element 300 is elongated from the light-in end 310 to the light-out end 320, and the angle between the optical axis 330 and the first light beam 210 is greater than 15 degrees and less than 75 degrees; more preferably, the light guide element 300 is elongated from the light-in end 310 to the light-out end 320, and the angle between the optical axis 330 and the first light beam 210 is greater than 30 degrees and less than 60 degrees.
[0049] In the preferred embodiment of the present application, the first position is the optical axis center 410 of the light-receiving mirror 400. The first light beam 210 irradiates to the optical axis center 410 of the light-receiving mirror 400, and the spot shape is not easy to distort, thereby hitting a predetermined spot.
[0050] When the central axis of the first light beam 210 is perpendicular to the plane where the light-receiving mirror 400 is located, the optical axis of the optical lens coincides with the central axis of the first light beam 210.
[0051] In the preferred embodiment of the present application, a rotation drive 600 is further included to drive the rotation of the light guide element 300. When the light guide element 300 rotates in the light path, the light-in end 310 of the light guide element 300 always receives the first light beam 210. That is, the light-out end 320 of the light guide element 300 always has the second light beam 220 emitted, and the deflected spot will not suddenly disappear.
[0052] Preferably, when the light guide element 300 rotates in the optical path, the center position of the light-incident end 310 of the light guide element 300 remains unchanged, and it always receives all of the first light beam 210. That is, the light guide element 300 achieves rotation by fixing the light-incident end 310 to the rotating seat 640.
[0053] In other embodiments, other parts of the light guide element 300 can be fixed to the rotating base 640 to achieve rotation. When the middle part of the light guide element 300 is fixed to the rotating base 640, the positions of the light-incident end 310 and the light-exit end 320 of the light guide element 300 will change with its own rotation. When the light-exit end 320 of the light guide element 300 is fixed to the rotating base 640, only the position of the light-incident end 310 of the light guide element 300 will change with its own rotation.
[0054] In a preferred embodiment of the present invention, when the light guide element 300 rotates in the optical path, the second light beam 220 is directed towards different positions of the same light receiving mirror 400. This allows the deflected light spot to move continuously, and even deform continuously (when the curvature is different at different positions), resulting in richer light effects.
[0055] That is, when the light guide element 300 rotates in the optical path, the second beam 220 will not illuminate a position outside the corresponding light receiving mirror 400, thus avoiding stray light or sudden disappearance of the deflected light spot, resulting in a more natural light effect.
[0056] When the light guide element 300 rotates in the optical path, and the second beam 220 illuminates different positions of curvature on the light receiving mirror 400, the deflected light spot that is finally projected will continuously produce different deformations, resulting in a rich dynamic effect.
[0057] In a preferred embodiment of the present invention, the first position is the optical axis 410 of the light-collecting mirror 400. When the light guide element 300 rotates in the optical path, the second light beam 220 illuminates the ring of the light-collecting mirror 400 with its own optical axis 410 as the center. This enables the deflected light spot to move in a circle around the preset light spot at the position on the projection surface.
[0058] In addition, generally speaking, the central portion of the light-collecting mirror 400, excluding the edge position, is rotationally symmetrical about its own optical axis 410. When the second beam 220 is irradiated onto the ring of the light-collecting mirror 400 with its own optical axis 410 as the center, the deflected light spot will move in a circle around the projection of the optical axis 410 of the light-collecting mirror 400 onto the projection surface, and the shape of the deflected light spot will not change, but will rotate as a whole (not rotate on its own axis).
[0059] likeFigures 3 to 5 In the preferred embodiment of the present application, the light source 200 is multiple, each of the light source 200 corresponds to a light receiving mirror 400, at least one of the light source 200 corresponds to the light guide element 300 provided with the cut-in / cut-out light path. Multiple light sources 200 can work together to produce light effects, or some of the light sources 200 can be configured with the light guide element 300, so as to realize the deflection of its light path and produce special light effects.
[0060] Preferably, one or more of the plurality of light sources 200 is arranged in the middle, and the remaining light sources 200 are arranged as a circular ring with the middle as the center.
[0061] In this embodiment, four light sources 200 are arranged in the middle, and the remaining light sources 200 are arranged with the center of the rectangle as the center. Specifically, the number of the remaining light sources 200 is 10.
[0062] Preferably, all the light receiving mirrors 400 are spliced (the splicing place can be provided with a grid), and the whole formed by all the light receiving mirrors 400 is circular.
[0063] As Figure 1 And Figure 5 In the preferred embodiment of the present application, multiple light sources 200 are provided with light guide elements 300 that cut in / cut out the light path, and each light guide element 300 is provided with a rotation drive 600 that drives its rotation. The movement drive 500 and / or the rotation drive 600 are independent of each other. Each of the movement drives 500 is independent of each other, so that the light guide elements 300 can be selected according to the needs of the light sources 200, and each of the rotation drives 600 is independent of each other, so that the light guide elements 300 can be rotated according to the needs of the light sources 200, with high degree of freedom and complex light effects.
[0064] In other embodiments, the movement drive 500 and / or the rotation drive 600 corresponding to the light guide element 300 can also be synchronized with each other, simultaneously cutting in / cutting out the light path and / or rotating simultaneously.
[0065] Preferably, at least four light sources 200 are provided with light guide elements 300 that cut in / cut out the light path.
[0066] Preferably, the light sources 200 corresponding to the light guide elements 300 that cut in / cut out the light path are arranged in a row, a cross, a radial, a circle or a rectangle, etc. Regular shape.
[0067] In the embodiment, the moving driver 500 comprises a moving driver 500 motor and a swing arm 520 connected with the rotating shaft of the moving driver 500 motor, the light guide element 300 is arranged on the swing arm 520, the swing arm 520 is provided with a light transmission hole 530 corresponding to the light guide element 300; the rotating driver 600 comprises a rotating motor 610, a driving wheel 620 connected with the rotating shaft of the rotating motor 610, a transition wheel 630 pivoted on the swing arm 520 and coaxial with the rotating shaft of the driving motor, and a rotating seat 640 pivoted on the swing arm 520, the light guide element 300 is fixed on the rotating seat 640, and the driving wheel 620 and the transition wheel 630 and the transition wheel 630 and the rotating seat 640 are connected by a synchronous belt 650 respectively.
[0068] In the preferred embodiment of the present application, only the light source 200 located at the outermost periphery is provided with the light guide element 300 with cut-in / cut-out light path. The light guide element 300 with cut-in / cut-out light path arranged in the peripheral space can add the function of light path deflection without changing the existing lamp as much as possible.
[0069] Preferably, the light source 200 located at the outermost periphery is arranged in a circle.
[0070] In the preferred embodiment of the present application, a focusing drive for driving the light collecting mirror 400 is further included. By driving the light collecting mirror 400 to approach or move away from the light source 200, the zooming of the light spot can be realized, which is combined with the deflection of the light path and the deformation of the light spot by the light guide element 300, so that rich effects can be realized.
[0071] In the embodiment, the lamp holder 100 is supported and rotated by the arm 700, and the arm 700 is supported and rotated by the machine box 800.
[0072] As shown in Figure 6 , when the 10 light sources 200 provided with the light guide element 300 with cut-in / cut-out light path are arranged in a circle, the deflected light spot changes (from left to right) when the light collecting mirror 400 gradually approaches the light source 200. It should be noted that the light guide element 300 does not rotate at this time.
