Description

Technical Field

[0001] This utility model relates to the field of musical instrument lighting technology, and in particular to a piano ambient light and a piano. Background Technology

[0002] A piano ambient light is a lighting fixture designed specifically for pianos. Its core function is to provide uniform light, ensuring that sheet music is clearly readable and fully covers the key area.

[0003] To enhance the premium feel and visual appeal of their products, some existing piano ambient lights employ a design that integrates multiple types of LED chips. These chips can create rich light and shadow effects by alternating their illumination or changing their emission modes. However, this multi-chip configuration not only significantly increases the production cost of the lighting fixture (due to the material cost of the LED chips themselves), but also requires additional control circuitry to realize the lighting effect switching functionality. This not only increases the structural complexity of the piano ambient lights but also further drives up the overall production cost. Utility Model Content

[0004] The main purpose of this invention is to propose a piano ambient light and a piano, aiming to solve the problem of high production costs of existing piano ambient lights.

[0005] To achieve the above objectives, the present invention provides a piano ambient light, comprising:

[0006] The lamp housing includes a housing body and a light-transmitting cover plate. The housing body forms a mounting cavity with an opening on one side, and the light-transmitting cover plate covers the opening.

[0007] A first reflector is attached to the cavity wall of the mounting cavity;

[0008] A drive assembly, comprising a drive component and a rotating shaft, wherein the rotating shaft is disposed within the mounting cavity;

[0009] A second reflector is mounted on the rotating shaft;

[0010] A light panel is installed in the mounting cavity. The light panel has a plurality of LED beads spaced apart along its extension direction. The light source emitted by the LED beads is used to project onto the first reflector. The first reflector reflects the light source to the second reflector. The driving member is used to drive the rotating shaft to rotate, thereby driving the second reflector to rotate and reflecting the light source onto the light-transmitting cover plate.

[0011] In one embodiment, the cross-section of the cavity wall of the mounting cavity is arc-shaped, the first reflective element is reflective paper, and the first reflective element is attached to the cavity wall of the mounting cavity.

[0012] In one embodiment, the second reflector is a reflective sheet, and the second reflector has a plurality of mounting openings spaced apart along its length, with the rotating shaft passing through a portion of the mounting openings.

[0013] In one embodiment, the piano ambient light further includes multiple support frames and multiple limiting frames. The multiple support frames and multiple limiting frames are spaced apart in the mounting cavity along the length direction of the shell body. The support frames are located near the opening of the mounting cavity. The multiple limiting frames and multiple support frames cooperate to form a clamping space, and the multiple limiting frames and multiple support frames clamp the light panel in the clamping space.

[0014] In one embodiment, the support frame forms an inclined surface on one side facing the mounting cavity, and the lamp panel is inclined and fits against the inclined surface.

[0015] In one embodiment, the angle between the lamp panel and the horizontal plane is 35 to 45 degrees.

[0016] In one embodiment, the driving element is an electric motor disposed within the mounting cavity.

[0017] In one embodiment, the light-transmitting cover plate has multiple light-transmitting openings, which are evenly spaced and arranged on the light-transmitting cover plate.

[0018] In one embodiment, the piano ambient light further includes a non-woven fabric disposed on the side of the light-transmitting cover facing the mounting cavity.

[0019] In addition, this utility model also discloses a piano that includes the aforementioned piano ambient light.

[0020] In this invention, the light emitted by the LED beads first illuminates the first reflector on the arc-shaped cavity wall, and then reflects onto the second reflector. A driving component rotates the shaft, causing the second reflector mounted on the shaft to rotate as well, continuously changing the light reflection angle. The rotating second reflector performs a secondary reflection of the light beam from the first reflector onto the light-transmitting cover, thus achieving a light and shadow effect. This eliminates the need for a control circuit to control the on / off state of different LED beads, reducing the structural complexity of the piano ambient light and lowering production costs.

[0033] In existing technologies, piano lighting fixtures generally employ a control method that alternately illuminates multiple types of LEDs to achieve light and shadow effects. This design requires the configuration of various light-emitting elements and corresponding control circuits, leading to a complex internal structure of the fixture. When a smoke-like light effect is desired, the number and arrangement density of LEDs are typically increased, which not only raises material costs but also increases the load on the circuit control module.

[0034] To address the aforementioned issues, researchers noticed the potential of dynamic optical elements to alter the shape of the light path. Through numerous experiments, they discovered that by using a rotatable reflective surface in conjunction with a fixed reflective surface, light from a single light source could be reflected along multiple paths. This physical reflection mechanism replaces the traditional electronic control method of alternating light emission from multiple LEDs, effectively reducing circuit complexity. While ensuring uniform light distribution, the dynamic reflection effect produced by the rotating reflective surface can simulate a visual effect similar to smoke diffusion.

[0035] This utility model proposes a piano ambient light.

[0036] Please see Figures 1 to 3In one embodiment of this utility model, the piano ambient light 100 includes a lamp housing 3, a first reflector 1, a driving assembly 4, a second reflector 2, and a lamp panel 5. The lamp housing 3 includes a housing body 31 and a light-transmitting cover 32. The housing body 31 forms a mounting cavity 311 with an opening on one side, and the light-transmitting cover 32 covers the opening. The first reflector 1 is attached to the cavity wall of the mounting cavity 311. The driving assembly 4 includes a driving member 41 and a rotating shaft 42, and the rotating shaft 42 is disposed in the mounting cavity 311. The second reflector 2 is mounted on the rotating shaft 42. The lamp panel 5 is mounted in the mounting cavity 311. The lamp panel 5 has multiple LED beads spaced apart along its extension direction. The light source emitted by the LED beads is projected onto the first reflector 1. The first reflector 1 reflects the light source to the second reflector 2. The driving member 41 drives the rotating shaft 42 to rotate, thereby driving the second reflector 2 to rotate and reflecting the light source to the light-transmitting cover 32.

[0037] In this embodiment, the mounting cavity 311 extends in the left-right direction, and both the lamp panel 5 and the rotating shaft 42 extend in the left-right direction and are disposed within the mounting cavity 311. Specifically, after the piano ambient light 100 in this embodiment is activated, the LED beads on the lamp panel 5 light up. The light emitted by the LED beads first illuminates the first reflector 1 on the arc-shaped cavity wall, and after reflection, forms a diffused beam, which is then reflected onto the second reflector 2. The driving member 41 drives the rotating shaft 42 to rotate, and the second reflector 2 mounted on the rotating shaft 42 rotates under the drive of the rotating shaft 42, causing the second reflector 2 to continuously change the light reflection angle. The rotating second reflector 2 performs a secondary reflection of the reflected beam from the first reflector 1 and reflects it onto the light-transmitting cover plate 32, thereby achieving the illusion of light and shadow.

[0038] Compared to existing technologies, traditional solutions rely on multiple sets of LEDs emitting light alternately to create dynamic effects, requiring complex control circuits and heat dissipation structures. This solution uses a single type of LED in conjunction with a mechanical reflection system, reducing the number of LEDs used while maintaining the same luminous efficacy. Furthermore, it eliminates the need for control circuits to control the on / off state of different LEDs, thus reducing the structural complexity of the piano ambient light 100 and lowering production costs.

[0039] In one embodiment, the cross-section of the cavity wall of the mounting cavity 311 is arc-shaped, and the first reflective element 1 is reflective paper, which is attached to the cavity wall of the mounting cavity 311. The arc-shaped cross-section of the cavity wall of the mounting cavity 311 means that the cross-sectional shape of the mounting cavity 311 in the front-back direction is arc-shaped, allowing the first reflective element 1 to be arranged in an arc shape after being attached to the cavity wall of the mounting cavity 311, thereby enabling the first reflective element 1 to achieve uniform light coverage.

[0040] Specifically, the light emitted by the light source is projected onto the surface of the arc-shaped cavity wall by the LED beads, and then scattered by the reflection of the first reflector 1, resulting in a uniform distribution of light within the cavity. The geometric characteristics of the arc-shaped cavity wall allow the light to diffuse naturally during reflection, avoiding excessively high or low local light intensity; the high reflectivity of the first reflector 1 reduces energy loss of light within the cavity, thus achieving uniform illumination coverage while reducing the number of LED beads.

[0041] Compared to existing technologies, traditional piano ambient lights 100 require multiple LEDs to be lit alternately or complex optical lens systems to achieve uniform illumination, resulting in complex structures and high costs. In contrast, this solution, through the synergistic effect of the curved cavity wall and the first reflector 1, requires only a small number of LEDs and achieves equivalent lighting effects through optimized reflection path design, without the need for additional control circuits or precision optical components.

[0042] Through the above technical solution, this application significantly reduces the number of LED beads required while ensuring the uniformity of illumination in the piano key area and sheet music. At the same time, it simplifies the internal structure of the lamp and avoids the problems of circuit complexity and increased material costs caused by multiple LED bead configurations.

[0043] In one embodiment, please refer to Figure 4 and Figure 5 The second reflector 2 is a reflective sheet, and it has multiple mounting openings 21 spaced apart along its length. The rotating shaft 42 passes through some of these mounting openings 21. The reflective sheet is a thin, sheet-like optical element made of a highly reflective material, specifically a PET film or metal foil with an aluminum-coated surface. It is flexible and bendable, adapting to angular changes during the rotation of the rotating shaft 42. The mounting openings 21 are through-hole structures regularly distributed along the left-right direction, formed by stamping or laser cutting. Specifically, by designing the reflective sheet with multiple mounting openings 21, the rotating shaft 42 can selectively pass through specific mounting openings 21 to fix the reflective sheet. When the driving component 41 drives the rotating shaft 42 to rotate, the reflective sheet rotates synchronously around the axis of the rotating shaft 42, and the path of the light reflected from its surface changes accordingly. Meanwhile, the highly reflective surface of the reflector can efficiently reflect the light emitted by the lamp panel 5 to the light-transmitting cover 32. By adjusting the position of the rotating shaft 42, the installation angle of the reflector can be changed, thereby controlling the area covered by the reflected light.

[0044] Through the above technical solution, this application achieves uniform light distribution while reducing the number of LEDs and the complexity of the control circuit. The high reflectivity and adjustable installation angle of the reflector allow a single light source to cover the piano keys and sheet music area without relying on multiple types of LEDs working alternately. The partial through-hole installation method of the mounting port 21 ensures a stable connection between the reflector and the rotating shaft 42 while allowing the unfixed area to deform freely, avoiding distortion of the reflective surface due to material rigidity during rotation, thereby ensuring precise control of the light projection direction.

[0045] In one embodiment, please refer to Figure 1 and Figure 2 The piano ambient light 100 also includes multiple support frames 6 and multiple limiting frames 7. The support frames 6 and limiting frames 7 are spaced apart along the length of the housing body 31 within the mounting cavity 311. The support frames 6 are positioned near the opening of the mounting cavity 311. The multiple limiting frames 7 and multiple support frames 6 cooperate to form a clamping space 8, which clamps the light panel 5 within the clamping space 8. The light panel 5 is doubly fixed by the multi-point inclined surface support and the limiting frames 7, achieving stable positioning without the need for screws or other fasteners. The placement of the support frames 6 near the opening allows the tilt angle of the light panel 5 to be closer to the light-transmitting cover plate 32, optimizing the transmission efficiency of the light source reflection path.

[0046] Through the above technical solution, this application achieves non-destructive and rapid installation of the lamp panel 5, reducing the number of parts such as fixing screws, and lowering material costs and assembly time. The cooperative structure of the support frame 6 and the limiting frame 7 ensures a uniform force distribution on the lamp panel 5, avoiding localized squeezing damage caused by traditional fixing methods. This installation method ensures the positioning accuracy of the optical components while making the disassembly and maintenance of the lamp panel 5 more convenient, significantly improving product maintainability.

[0047] In one embodiment, the support frame 6 forms an inclined surface on the side facing the mounting cavity 311, and the lamp plate 5 is inclined and fits against the inclined surface. Specifically, the support frame 6 forms surface contact with the lamp plate 5 through the inclined surface, and the lamp plate 5 naturally fits against the inclined surface under the action of gravity. There is no need to adjust the angle of the lamp plate 5 during installation. The geometric constraints of the inclined surface directly limit the installation posture of the lamp plate 5, ensuring that the light from multiple lamps is projected onto the first reflector 1 at a uniform angle. The contact surface between the support frame 6 and the lamp plate 5 is fixed by friction, eliminating the need for additional parts required for traditional bolt locking or clip fixing.

[0048] In one embodiment, the angle between the lamp plate 5 and the horizontal plane is 35 to 45 degrees. This angle refers to the tilt angle of the lamp plate 5 relative to the horizontal reference plane during installation. Specifically, this can be achieved by using the tilted surface of the support frame 6 in conjunction with the limiting frame 7 for fixation and adjustment. This angle range has been verified through optical path simulation, ensuring that the LED light source is projected onto the surface of the first reflector 1 at the optimal incident angle. Specifically, when the lamp plate 5 is installed at this angle range, the light emitted by the multiple LEDs on its surface is projected onto the first reflector 1 at a specific incident angle, and after reflection, forms a stable light path to the second reflector 2. This angle range keeps the incident angle of light on the surface of the first reflector 1 within the range of highest reflection efficiency, avoiding light attenuation due to excessively long reflection paths caused by excessively small angles, while also preventing light scattering caused by excessively large angles. Therefore, even with a reduced number of LEDs, uniform light distribution on the second reflector 2 can still be achieved by precisely controlling the reflection path, ultimately allowing the rotating second reflector 2 to effectively cover the piano key area. In this embodiment, the tilt angle of the lamp panel 5 is preferably 40 degrees.

[0049] In one embodiment, the drive element 41 is an electric motor disposed within the mounting cavity 311. Specifically, the output shaft of the electric motor is directly connected to the rotating shaft 42, and the motor speed is adjusted by an electronic control signal to precisely control the rotation angle of the second reflector 2. Because the electric motor itself has high integration and a standardized interface, there is no need for additional reduction gear sets or transmission linkages, thus simplifying the overall structure of the drive assembly 4. In other embodiments, the drive element 41 can also drive a motor; this embodiment is not limited to this.

[0050] In one embodiment, the light-transmitting cover plate 32 has multiple light-transmitting openings, which are evenly spaced and arranged on the light-transmitting cover plate 32. In this embodiment, the light-transmitting cover plate 32 can be made of black iron mesh, and the multiple light-transmitting openings on the light-transmitting cover plate 32 facilitate the transmission of light.

[0051] In one embodiment, the piano ambient light 100 further includes non-woven fabric 9, which is disposed on the side of the light-transmitting cover 32 facing the mounting cavity 311. The non-woven fabric 9 refers to a non-woven material formed by oriented or randomly arranged fibers through friction, cohesion, or bonding. Specifically, it can be made of polypropylene or polyester fibers, and its surface has a porous structure, enabling it to scatter and diffuse light. In this technical solution, the non-woven fabric 9 is arranged between the light-transmitting cover 32 and the mounting cavity 311 to eliminate local light spots formed by direct light from the LED beads and to diffuse the reflected light secondaryly. Specifically, the light emitted by the LED beads is reflected by the first reflector 1 to the second reflector 2, and the second reflector 2 projects the light towards the light-transmitting cover 32 during rotation. The non-woven fabric 9 is located at the end of the light propagation path, and through the gaps between the fibers, it refracts and scatters the light multiple times, uniformly covering the light-dark boundary areas that might have been caused by the interleaved arrangement of the LED beads. Because the non-woven fabric 9 itself has soft light properties, it can achieve light uniformity without relying on multiple LEDs to be lit alternately or complex control circuits, thereby reducing the number of LEDs and simplifying the circuit layout.

[0052] In addition, this utility model also discloses a piano, which includes the aforementioned piano ambient light 100. Since this piano adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here.
