Abstract
Description
Technical Field
[0001] This utility model relates to the field of stage lighting, and in particular to a zone-dimming lighting fixture. Background Technology
[0002] In recent years, "smart glass" that can adjust the light transmittance according to demand has appeared more and more in people's production and life; for example, it is used in building and car windows to adjust the amount of visible light transmitted according to demand; and even "smart glass" is made opaque to protect personal privacy.
[0003] However, current smart glass products on the market use a single-section adjustment of the fogging effect to achieve dimming. These methods only allow for overall clarity or fogging, offering limited variation and low light utilization. Alternatively, angled diffusers can be used to change the angle and shape of the light, but changing the light angle requires disassembling and reassembling parts, which is cumbersome. Both of these methods offer limited light variation effects and cannot adapt to changing fogging effects as needed, making them unsuitable for stage performances. Utility Model Content
[0004] The purpose of this invention is to propose a zone-dimming lighting fixture to solve the problem that existing dimming glass cannot change its fogging effect in a timely manner as needed, making it difficult to match the performance effect on stage.
[0005] To achieve this objective, the present invention adopts the following technical solution:
[0006] This utility model provides a zoned dimming lamp, including a light source, a control board and a dimming glass, wherein the dimming glass includes a light-transmitting substrate and several dimming films;
[0007] Several dimming films are disposed on a light-transmitting substrate; each dimming film has a positive electrode and a negative electrode, which are electrically connected to a control main board via circuits; the control main board is connected to an external power supply to control the voltage input to the dimming films; the light source is disposed on one side of the light-transmitting substrate.
[0008] In the aforementioned zoned dimming lamp, the dimming film is rectangular, and the dimming films are arranged side by side on the light-transmitting substrate along the width direction of the light-transmitting substrate.
[0009] In the zoned dimming lamp, the dimming film is annular, with one dimming film covering the outer periphery of the next dimming film.
[0010] In the aforementioned zoned dimming lamp, the dimming film is square, and two or more dimming films are arranged side by side to form a dimming film array. The dimming film array is arranged side by side to form a dimming film matrix, and the dimming film matrix is disposed on a light-transmitting substrate.
[0011] In the aforementioned zoned dimming lamp, the dimming glass further includes a bottom electrode, which is electrically connected to the negative electrode.
[0012] In the zoned dimming lighting fixture, the light source includes a reflector and an LED panel. The size and shape of the light outlet of the reflector are adapted to the size and shape of the dimming glass, and the LED panel is disposed at the light inlet of the reflector.
[0013] In the aforementioned zoned dimming lamp, several dimming films are located between the light source and the light-transmitting substrate.
[0014] In the aforementioned zone-dimming lighting fixture, the light-transmitting substrate is made of glass or plastic.
[0015] One of the technical solutions of this utility model can have the following beneficial effects:
[0016] The zone-dimming lighting fixture controls the atomization level of each dimming film by controlling the AC voltage of the main board. By changing the light transmittance of the dimming film, the light source passes through the light-transmitting substrate, which can shape the shape of multiple light zones, making the light output effect versatile. It can achieve stepless adjustment of clear and atomized effects, and can emit clear beams and blurred diffusion effects, thereby enhancing the stage effect. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0028] Please refer to Figures 1-6 This utility model provides a zoned dimming lamp, including a light source 1, a control board 2 and a dimming glass 3, wherein the dimming glass 3 includes a light-transmitting substrate 31 and a plurality of dimming films 32;
[0029] Several dimming films 32 are disposed on a light-transmitting substrate 31; each dimming film 32 is provided with a positive electrode 321 and a negative electrode 322, and the positive electrode 321 and the negative electrode 322 are electrically connected to the control main board 2 through circuits; the control main board 2 is connected to an external power supply and is used to control the voltage input to the dimming film 32; the light source 1 is disposed on one side of the light-transmitting substrate 31.
[0030] The zone-dimming lighting fixture controls the atomization degree of each dimming film 32 by controlling the AC voltage of the main board 2. By changing the light transmittance of the dimming film 32, the light source 1 can pass through the light-transmitting substrate 31, which can shape the shape of multiple light zones, making the light output effect varied and achieving stepless adjustment of the clear and atomized effects. It can emit clear beams and blurred diffusion effects, thereby enhancing the stage effect.
[0031] Light source 1 emits light, and control board 2 controls the voltage by sending a PWM signal, thereby changing the light transmittance of dimming film 32 to create a clear or hazy light beam effect. Furthermore, control board 2 can apply continuous voltage to change the beam diffusion angle of the lamp, allowing light emitted from adjacent dimming zones to interfere with each other, achieving complex hazy and halo effects. The shape of dimming film 32 can be selected according to actual needs, forming dimming zones of corresponding shapes. The shape of the dimming zones, combined with different beam diffusion angles, can create a bright, beautiful, and dreamlike effect. Transparent substrate 31 serves to fix dimming film 32 and allow light to pass through.
[0032] In one specific embodiment of this utility model, the control motherboard 2 controls the voltage by emitting a PWM signal to adjust the atomization degree of the dimming film 32. After the light source 1 passes through the light-transmitting substrate 31, the light emission angle of the lamp can be changed. The voltage adjustment range of the control motherboard 2 is 0-60V. The lower the voltage, the larger the light emission angle and the more atomized the effect; the higher the voltage, the smaller the light emission angle and the clearer the effect.
[0033] In one specific embodiment of this utility model, the dimming film 32 is rectangular, and the dimming film 32 is arranged side by side on the light-transmitting substrate 31 along the width direction of the light-transmitting substrate 31.
[0034] In the above embodiment, four rectangular dimming films 32 of the same size are included. Using this structure, each dimming film 32 can have its internal liquid crystal molecules rearranged by adjusting the voltage of the main board 2, thereby changing the light transmittance of adjacent dimming films 32. The four rectangular dimming films 32 divide the light-transmitting substrate 31 into four dimming regions. Adjacent dimming regions can influence each other, resulting in uneven light emission and creating layered light variations.
[0035] In one specific embodiment of this utility model, the dimming film 32 is annular, and the previous dimming film 32 is sleeved on the outer periphery of the next dimming film 32.
[0036] In the above embodiment, three annular dimming films 32 of different sizes are included, with the previous dimming film 32 fitted around the outer periphery of the next dimming film 32. The innermost dimming film 32 has a through hole, through which some light can be directly emitted from the light-transmitting substrate 31. Similarly, using the above structure, each dimming film 32 can have its internal liquid crystal molecules rearranged by adjusting the voltage of the main board 2, thereby changing the light transmittance of adjacent dimming films 32. The three annular dimming films 32 are concentrically arranged to form three annular dimming areas. In use, they can affect the light emitted from the through hole, and adjacent dimming films 32 will also be affected, producing a halo effect.
[0037] In one specific embodiment of this utility model, the dimming film 32 is square, two or more dimming films 32 are arranged side by side to form a dimming film array, the dimming film array is arranged side by side to form a dimming film matrix, and the dimming film matrix is disposed on the light-transmitting substrate 31.
[0038] Specifically, four dimming films 32 are arranged side by side to form a dimming film array, and then two dimming film arrays are arranged side by side to form a 4×2 dimming film matrix.
[0039] Similarly, using the above structure, each dimming film 32 can adjust the voltage by controlling the main board 2, causing the liquid crystal molecules inside the dimming film 32 to change their arrangement and combination, thereby changing the light transmittance of adjacent dimming films 32. This results in different angles and brightness of the light emitted by adjacent dimming films 32, thus causing the light from adjacent dimming films 32 to affect each other. Since the eight dimming films 32 are combined to form a 4×2 dimming film matrix, forming eight square dimming areas, during use, stepless adjustment and multi-level adjustment of clear and fogged effects can be achieved, eliminating the uneven light emitted by the light-transmitting substrate 31.
[0040] Specifically, the dimming glass 3 further includes a bottom electrode 33, which is electrically connected to the negative electrode 322.
[0041] In one specific embodiment of this utility model, the negative electrode 322 is electrically connected to the control motherboard 2 through the bottom electrode 33, making the circuit layout more reasonable and clear, and facilitating subsequent inspection and maintenance by maintenance personnel.
[0042] Specifically, the light source 1 includes a reflector 11 and an LED light panel 12. The size and shape of the light outlet of the reflector 11 are adapted to the size and shape of the dimming glass 3, and the LED light panel 12 is disposed at the light inlet of the reflector 11.
[0043] The reflector 11 can refer to existing light source reflectors. The reflector 11 adopts a parabolic curved surface design to reflect and guide the light emitted by the LED light panel 12 to the dimming glass 3, which can more effectively reduce light loss. The LED light panel 12 is connected to an external power supply and can emit light. The light passes through the reflector 11 and enters the dimming glass 3. The transmittance of the dimming film 32 is controlled by voltage to adjust the fogging effect of the light. The fogging effect can be changed in time as needed.
[0044] Specifically, several dimming films 32 are located between the light source 1 and the light-transmitting substrate 31.
[0045] By using the above structure, the dimming film 32 is placed between the light source 1 and the light-transmitting substrate 31, which enables dimming at the light source end, reduces excessive light entering the light-transmitting substrate 31, and improves brightness uniformity.
[0046] Optionally, the light-transmitting substrate 31 may be made of glass or plastic.
[0047] The dimming film 32 is attached to the surface of glass or plastic. Due to the high transparency of glass and plastic, it achieves high light transmittance, allowing most light to pass through. Furthermore, it possesses good hardness and chemical stability, resulting in a long service life and meeting the requirements of dimming lighting fixtures.
[0048] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
