Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stage lamps, and more particularly to a lamp that utilizes edge light to generate light effects. Background Art
[0002] Stage lighting is a very important component of performing arts. It not only enhances the stage effect, but also helps the audience better understand the plot and the emotions of the characters. In the process of using stage lights, the center part of the light beam is generally used for spot imaging because it is highly parallel and not easy to diverge. The edge part of the light beam is constrained as much as possible to avoid scattering, which affects the spot imaging effect, such as forming a halo or causing the edge of the light spot to produce mixed colors. However, this operation is more difficult. Some lamps even directly block the edge of the light beam to prevent it from emitting from the lamp, but this will reduce the utilization rate of light and cause serious heating inside the lamp. Utility Model Content
[0003] In order to overcome at least one of the defects of the above-mentioned prior art, the present invention provides a lamp that uses edge light to produce light effects. The edge part of the light beam is used in another form, which neither affects the imaging of the light spot nor causes serious heating inside the lamp, and can also produce special light effects.
[0004] To solve the above technical problems, the technical solution adopted by the present invention is as follows: a lamp that uses edge light to generate a light effect is provided, comprising a lamp base with a projection hole, and a first reflector cup, a second reflector cup, a first lens, a second lens, and a light-emitting assembly located inside the lamp base. The first reflector cup is externally sleeved with the second reflector cup, and the central axes of the first reflector cup and the second reflector cup coincide with each other and their open light outlets face the same direction. The bottoms of the first reflector cup and the second reflector cup are both opened to form a light inlet. The first lens is disposed at the light inlet of the second reflector cup. Light emitted by the light-emitting assembly enters the first reflector cup through the light inlet of the first reflector cup, and a central portion of the light beam passes through the first lens and the light outlet of the second reflector cup in sequence, and is then projected out through the second lens at the projection hole. An edge portion of the light beam is reflected between the outer wall of the second reflector cup and the inner wall of the first reflector cup, and is then projected toward the transparent cover through the gap between the projection hole and the second lens.
[0005] The lamp that uses edge light to generate light effects produces an interactive effect on the stage by projecting the center portion of the light beam through the first lens and the second lens in sequence to form a light spot, while the edge portion of the light beam is reflected between the outer wall of the second reflector cup and the inner wall of the first reflector cup and then projected toward the transparent cover to light it up, so that the lamp itself can also generate light effects, which looks very cool. In this way, the light from the edge portion of the light beam is effectively utilized to avoid affecting the imaging of the light spot and causing internal heating of the lamp.
[0006] Furthermore, the light-emitting assembly includes a light source for emitting light and a light guide for mixing light. Light emitted by the light source is mixed by the light guide before entering the light inlet of the first reflective cup. The light guide can fully mix the light emitted by the light source, ensuring that the mixed light has a high degree of color or brightness uniformity on the output surface of the light guide.
[0007] Furthermore, the light emitting assembly further includes a light homogenizer for mixing light, and the light emitted by the light guide passes through the light homogenizer and then enters the light inlet of the first reflective cup. The light homogenizer can further improve the uniformity of the light emitted from the output surface of the light guide.
[0008] Furthermore, the first lens and the second lens form a positive focal length, so that the center portion of the light beam is narrowed after passing through the first lens and the second lens, producing a focusing effect.
[0009] Furthermore, a driving mechanism is included to drive the second reflector and the first lens to move along the central axis. The movement of the second reflector and the first lens can achieve the function of continuously changing the focal length, thereby realizing the zooming of the light spot imaging in the center of the light beam.
[0010] Furthermore, the second reflector is fixed to the inner wall of the first reflector, and the driving mechanism drives the first reflector to move the second reflector and the first lens. By directly driving the first reflector to move, the second reflector and the first lens can be moved, which makes driving more convenient and the structure simpler.
[0011] Furthermore, a ring-shaped LED light board is installed around the second lens on the side of the transparent cover close to the light-emitting assembly. The LED light board can achieve a dynamic lighting effect, and when the light source assembly is not working and the transparent cover is illuminated by the LED light board, the transparent cover can be seen to emit light alone.
[0012] Furthermore, a transparent cover covers the entire projection aperture, and a second lens is located on the side of the transparent cover closest to the light-emitting assembly. The transparent cover protects the lens from external factors such as dust, moisture, and impact. Furthermore, when the light source assembly is not operating and the transparent cover is illuminated by the LED light panel, the transparent cover's luminous area is larger, making it appear as if the entire projection aperture is luminous.
[0013] Furthermore, the portion of the transparent cover corresponding to the light passing through the second lens is a smooth and flat surface. The smooth and flat surface of the transparent cover has little effect on the transmission of light, can maintain high optical transmission efficiency, reduce light loss and glare, and improve imaging quality.
[0014] Furthermore, the second lens is fixed to the transparent cover. The transparent cover provides a mounting position for the second lens, that is, the transparent cover and the second lens can be disassembled and assembled as a whole, and no additional bracket is required inside the lamp head for installation, thereby simplifying the internal structure and facilitating maintenance.
[0015] Furthermore, the device further comprises a support frame for supporting the lamp head to rotate about a first axis and a base for supporting the support frame to rotate about a second axis. The support frame for supporting the rotation of the lamp head can rotate the lamp head left and right, and the base for supporting the rotation of the support frame can rotate the lamp head up and down, thereby achieving the movement of the light spot up, down, left and right.

To better illustrate the embodiments, some components in the drawings may be omitted, enlarged, or reduced in size, and do not represent actual product dimensions. Those skilled in the art will understand that some well-known structures and their descriptions may be omitted from the drawings.

[0023] like Figures 1 to 3The present invention provides a lamp that uses edge light to produce light effects, including a lamp head 100 with a projection hole 190, and a first reflector cup 110, a second reflector cup 120, a first lens 130, a second lens 140 and a light-emitting component 150 located in the lamp head 100. The first reflector cup 110 is externally mounted on the second reflector cup 120, and the central axes of the two coincide with each other and the open light outlets 112 face the same direction. The bottoms of the first reflector cup 110 and the second reflector cup 120 are both opened to form a light inlet 111. The first lens 130 is placed on the first reflector cup 110. At the light inlet 111 of the second reflector 120, light emitted by the light-emitting assembly 150 enters the first reflector 110 through the light inlet 111 of the first reflector 110. The central portion of the light beam passes through the first lens 130 and the light outlet 112 of the second reflector 120 in sequence, and is then projected out through the second lens 140 at the projection hole 190. The edge portion of the light beam is reflected between the outer wall of the second reflector 120 and the inner wall of the first reflector 110, and then is projected toward the transparent cover 160 through the gap between the projection hole 190 and the second lens 140.
[0024] The lamp that uses edge light to generate light effects produces an interactive effect on the stage by projecting the center portion of the light beam through the first lens 130 and the second lens 140 in sequence to form a light spot, while the edge portion of the light beam is reflected between the outer wall of the second reflector cup 120 and the inner wall of the first reflector cup 110 and then projected toward the transparent cover 160 to illuminate it, so that the lamp itself can also generate light effects, which looks very cool. In this way, the light from the edge portion of the light beam is effectively utilized to prevent it from affecting the imaging of the light spot and causing internal heating of the lamp.
[0025] It should be noted that the edge portion of the light beam is reflected between the outer wall of the second reflective cup 120 and the inner wall of the first reflective cup 110 and then projected toward the transparent cover 160 means that most of the light emitted from the gap between the projection hole 190 and the second lens 140 is projected toward the transparent cover 160, but not all of it, because some of the light will deviate from the second lens 140 due to the angle.
[0026] Preferably, the combined focus of the first lens 130 and the second lens 140 coincides with the combined focus of the first reflective cup 110 and the second reflective cup 120 , and the light-emitting surface of the light-emitting assembly 150 is located near the combined focus.
[0027] Preferably, the first lens 130 is mounted on the light inlet 111 of the second reflective cup 120 by means of a rotating buckle.
[0028] Preferably, the outer wall of the second reflective cup 120 and the inner wall of the first reflective cup 110 are provided with a reflective coating.
[0029] In a preferred embodiment of the present invention, the light-emitting assembly 150 includes a light source 151 for emitting light and a light guide 152 for mixing light. Light emitted by the light source 151 is mixed by the light guide 152 before entering the light inlet of the first reflective cup 110. The light guide 152 thoroughly mixes the light emitted by the light source 151, ensuring that the mixed light has a high degree of color or brightness uniformity on the output surface of the light guide 152. In this embodiment, the light guide 152 is secured by a bracket, with its lower end abutting the light source 151.
[0030] In a preferred embodiment of the present invention, the light-emitting assembly 150 further includes a light-mixing plate 153. Light emitted from the light guide 152 passes through the light-mixing plate 153 before entering the light inlet of the first reflective cup 110. The light-mixing plate 153 further improves the uniformity of light emitted from the output surface of the light guide 152. In this embodiment, the light-mixing plate 153 is secured by a cover connected to the bracket, abutting the output surface of the light guide 152.
[0031] In a preferred embodiment of the present invention, the first lens 130 and the second lens 140 form a positive focal length, so that the center portion of the light beam is narrowed after passing through the first lens 130 and the second lens 140, producing a focusing effect.
[0032] In a preferred embodiment of the present invention, a drive mechanism 170 is further included to drive the second reflector 120 and the first lens 130 to move along the central axis. The movement of the second reflector 120 and the first lens 130 can achieve the function of continuously changing the focal length, thereby achieving zooming in and out of the imaging spot at the center of the light beam.
[0033] In this embodiment, after the first lens 130 moves, the combined focus of the first lens 130 and the second lens 140 is within 5CM, preferably within 3CM, from the light emitting surface of the light emitting component 150 .
[0034] In a preferred embodiment of the present invention, the second reflector 120 is fixed to the inner wall of the first reflector 110, and the driving mechanism 170 drives the first reflector 110 to move the second reflector 120 and the first lens 130. Directly driving the first reflector 110 to move can achieve movement of the second reflector 120 and the first lens 130, making driving more convenient and the structure simpler.
[0035] In this embodiment, a connecting rod extends from the light outlet 112 of the second reflective cup 120 , and the connecting rod is fixed to the connecting post inside the first reflective cup 110 by three screws.
[0036] In this embodiment, the driving mechanism 170 is a screw motor, and a threaded sleeve cooperating with the screw is provided on the outside of the first reflective cup 110 .
[0037] In a preferred embodiment of the present invention, a ring-shaped LED light board 180 is further installed on one side of the light-emitting assembly 150 around the second lens 140. The LED light board 180 can achieve a dynamic lighting effect, and when the light source 151 assembly is not working and the transparent cover 160 is illuminated by the LED light board 180, the effect of the transparent cover 160 emitting light alone can be seen.
[0038] In this embodiment, the control of the LED light board 180 and the light emitting assembly 150 are independent of each other, and the LED light board 180 can be point-controlled, serially controlled, or overall controlled to achieve various effects.
[0039] In this embodiment, the LED light board 180 is fixed to the transparent cover 160 .
[0040] In this embodiment, each LED lamp bead on the LED lamp board 180 is a colored lamp bead or the LED lamp board 180 is provided with at least two LED lamp beads of different colors.
[0041] Optionally, the portion of the transparent cover 160 corresponding to the light emitted by the LED light board 180 is frosted to increase the brightness of this portion and provide a more obvious lighting effect.
[0042] In a preferred embodiment of the present invention, a transparent cover 160 covers the entire projection aperture 190, and the second lens 140 is located on the side of the transparent cover 160 closest to the light-emitting assembly 150. The transparent cover 160 protects the lens from external factors such as dust, moisture, and impact. Furthermore, when the light source 151 assembly is not operating and the transparent cover 160 is illuminated by the LED light panel 180, the luminous area of the transparent cover 160 is larger, making it appear as if the entire projection aperture 190 is emitting light.
[0043] In a preferred embodiment of the present invention, the portion of transparent cover 160 corresponding to the light passing through second lens 140 is a smooth, flat surface. The smooth, flat surface of transparent cover 160 has minimal impact on light transmission, maintaining high optical transmission efficiency, reducing light loss and glare, and improving imaging quality.
[0044] Optionally, the portion of the transparent cover 160 corresponding to the light projected from the gap between the projection hole 190 and the second lens 140 is frosted to increase the brightness of this portion and provide a more obvious lighting effect.
[0045] In a preferred embodiment of the present invention, the second lens 140 is fixed to the transparent cover 160. The transparent cover 160 provides a mounting position for the second lens 140, that is, the transparent cover 160 and the second lens 140 can be removed and installed as a whole, and no additional bracket is required inside the lamp head 100 for installation, which simplifies the internal structure and facilitates maintenance.
[0046] In this embodiment, the second lens 140 is fixed to the transparent cover 160 by three screws.
[0047] like Figure 4 In a preferred embodiment of the present invention, the lamp head 100 further includes a support frame 200 for supporting the lamp head 100 to rotate about a first axis 210, and a base 300 for supporting the support frame 200 to rotate about a second axis 310. The support frame 200 supporting the rotation of the lamp head 100 can cause the lamp head 100 to rotate left and right, and the base 300 supporting the rotation of the support frame 200 can cause the lamp head 100 to rotate up and down, thereby achieving vertical and horizontal movement of the light spot.
[0048] The support frame 200 is annular, the lamp head 100 is pivotally connected to the front and rear inner sides of the support frame 200 , and the base 300 extends with two support arms pivotally connected to the left and right outer sides of the support frame 200 .
[0049] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
