Description

Technical Field

[0001] This utility model relates to a lamp, and more particularly to a lamp that can simulate natural dynamic lighting. Background Technology

[0002] Currently, there is a type of lighting fixture on the market that can simulate the lighting effects of natural sky and sunlight through Rayleigh scattering. Its core technology involves placing a Rayleigh scattering light-transmitting panel at the light outlet of the fixture, allowing light to undergo Rayleigh scattering as it passes through. When white light passes through the Rayleigh scattering panel, short-wavelength blue-violet light is scattered, giving the surface of the fixture a realistic blue sky effect, while the light projected downwards remains natural white light, thus simulating the effect of outdoor natural lighting.

[0003] However, the light sources inside these types of lamps are fixed, so they can only simulate static natural light and shadow at the light outlet, and cannot simulate the dynamic effects of sunlight moving and changing light.

[0004] Therefore, how to overcome the shortcomings of the above-mentioned lamps in simulating dynamic light and shadow effects has become an important issue that needs to be addressed by those skilled in the art. Utility Model Content

[0005] This invention overcomes the shortcomings of the above-mentioned technologies and provides a lamp that can simulate natural dynamic lighting.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lamp that can simulate natural dynamic lighting includes a lamp housing 1, wherein the lamp housing 1 has a downward-facing light-emitting hole 11, and a Rayleigh scattering light-transmitting plate 2 is covered at the light-emitting hole 11. A reflector 3 is provided inside the lamp housing 1 above the light-emitting hole 11. A light source 4 is also provided inside the lamp housing 1. The light source 4 is located to the side of the light-emitting hole 11, and the light emitted by the light source 4 is obliquely directed toward the reflector 3. A translation drive component 5 is also connected between the light source 4 and the lamp housing 1. The translation drive component 5 is used to drive the light source 4 to approach / move away from the light-emitting hole 11.

[0008] Preferably, the translation drive assembly 5 includes guide rails 51 disposed on both sides of the lamp housing 1. A drive shaft 52 is connected between the ends of the guide rails 51 away from the light emission hole 11. A drive motor 53 is fixed to one end of the guide rail 51 away from the light emission hole 11. The drive motor 53 is used to drive the drive shaft 52 to rotate. Both ends of the drive shaft 52 are provided with synchronous pulleys. Each guide rail 51 is provided with a synchronous belt sleeved on the synchronous pulley and driven by the synchronous pulley. Each synchronous belt is fixed with a slider 54 that can move forward and backward along the guide rail 51. The light source 4 is fixed between the sliders 54 on both sides.

[0009] Preferably, the reflector 3 is arranged parallel to the Rayleigh scattering light-transmitting plate 2; or the reflector 3 is not arranged parallel to the Rayleigh scattering light-transmitting plate 2; or the lamp housing 1 is provided with two reflectors 3, one of which is arranged parallel to the Rayleigh scattering light-transmitting plate 2 and the other is not arranged parallel to the Rayleigh scattering light-transmitting plate 2.

[0010] Preferably, the reflector 3 is connected to the lamp housing 1 by an electric adjustment bracket, which is used to change the angle between the reflector 3 and the Rayleigh scattering light-transmitting plate 2.

[0011] Preferably, the light source 4 is a long strip LED light or a circular LED light.

[0012] Preferably, when the light source 4 is a circular LED, the center line of the light source 4 is aligned with the center line of the Rayleigh scattering light-transmitting plate 2, or the light source 4 is offset on one of the left or right sides of the Rayleigh scattering light-transmitting plate 2.

[0013] Preferably, a rotating mechanism is also connected between the slider 54 and the light source 4, and the rotating mechanism is used to drive the light source 4 to rotate and change the angle of light emission.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This lighting fixture utilizes a reflector to emit light through a single reflection, effectively reducing the overall height of the lamp housing while maintaining a sense of depth in the light, thus significantly reducing the overall size of the fixture and lowering the installation threshold. In addition, a translation drive component is installed between the lamp housing and the light source. By dynamically adjusting the position of the light source through this component, the emitted light can be dynamically changed, simulating the dynamic changes of natural light and achieving a more realistic dynamic sky lighting effect.

Detailed Implementation

[0021] The following examples provide a more detailed description of the features and other related characteristics of this utility model, to facilitate understanding by those skilled in the art:

[0022] like Figures 1 to 5 As shown, a lamp that can simulate natural dynamic lighting includes a lamp housing 1, the lamp housing 1 having a downward-facing light-emitting hole 11, the light-emitting hole 11 being covered by a Rayleigh scattering light-transmitting plate 2, a reflector 3 located above the light-emitting hole 11 inside the lamp housing 1, a light source 4 also being located inside the lamp housing 1, the light source 4 being located to the side of the light-emitting hole 11, the light emitted by the light source 4 being obliquely directed toward the reflector 3, and a translation drive component 5 being connected between the light source 4 and the lamp housing 1, the translation drive component 5 being used to drive the light source 4 to approach / move away from the light-emitting hole 11.

[0023] The lamp in this design features a Rayleigh scattering light-transmitting plate 2 covering the light outlet 11, allowing light from inside the lamp housing 1 to be emitted through the light outlet 11 and achieve a natural light effect similar to conventional solutions. Additionally, a reflector 3 is installed above the light outlet 11, while the light source 4 is positioned to the side of the light outlet 11, angled towards the reflector 3. This allows the light to be reflected once by the reflector 3 before being emitted, effectively reducing the overall height of the lamp housing 1 while maintaining a sense of depth. Furthermore, a translation drive component 5 connects the lamp housing 1 and the light source 4. This component allows the light source 4 to move closer to or further away from the light outlet 11. As the light emitted by the light source 4 is reflected by the reflector 3 and then emitted back to the light outlet 11, the actual light emitted from the light outlet 11 changes accordingly with the position of the light source 4, thus simulating the dynamic effect of changing sunlight.

[0024] As described above, the lighting fixture in this case utilizes the reflector 3 to emit light through a single reflection, effectively reducing the overall height of the lamp housing 1 while maintaining the sense of depth in the light, thereby significantly reducing the overall size of the lighting fixture and lowering the installation threshold. In addition, this case also includes a translation drive component 5 between the lamp housing 1 and the light source 4. By dynamically adjusting the position of the light source 4 through the translation drive component 5, the light emitted by the lighting fixture can be dynamically changed, thereby simulating the effect of dynamic changes in natural light and achieving a more realistic dynamic sky lighting effect.

[0025] like Figures 2 to 5As shown, preferably, the translation drive assembly 5 includes guide rails 51 disposed on both sides of the lamp housing 1. A drive shaft 52 is connected between the ends of the guide rails 51 away from the light emission hole 11. A drive motor 53 is fixed to one end of the guide rail 51 away from the light emission hole 11. The drive motor 53 is used to drive the drive shaft 52 to rotate. Both ends of the drive shaft 52 are provided with synchronous pulleys. Each guide rail 51 is provided with a synchronous belt sleeved on the synchronous pulley and driven by the synchronous pulley. Each synchronous belt is fixed with a slider 54 that can move forward and backward along the guide rail 51. The light source 4 is fixed between the sliders 54 on both sides.

[0026] As described above, the translation drive assembly 5 of this invention includes guide rails 51 on both sides. Each guide rail 51 contains a slider 54 and a synchronous belt for moving the slider 54. A transmission shaft 52, driven by a drive motor 53, is connected between the two guide rails 51 to synchronously rotate the synchronous belts within the guide rails 51. The light source 4 is fixed between the two sliders 54. Thus, when the drive motor 53 operates, it can drive the sliders 54 on both sides to move synchronously via the transmission shaft 52 and the synchronous belt, thereby driving the light source 4 to move. The synchronous movement of the synchronous belts on both sides via the dual guide rails 51 and the transmission shaft 52 ensures that the light source 4 remains stable during movement, thereby improving the smoothness of dynamic lighting.

[0027] like Figures 2 to 5 As shown, preferably, the reflector 3 is arranged parallel to the Rayleigh scattering light-transmitting plate 2; or the reflector 3 is not arranged parallel to the Rayleigh scattering light-transmitting plate 2; or the lamp housing 1 is provided with two reflectors 3, one of which is arranged parallel to the Rayleigh scattering light-transmitting plate 2, and the other is not arranged parallel to the Rayleigh scattering light-transmitting plate 2.

[0028] As described above, the reflector 3 in this design can be set parallel to the Rayleigh scattering light-transmitting plate 2. This way, the light emitted by the light source 4, after being reflected by the reflector 3, will be obliquely incident on the Rayleigh scattering light-transmitting plate 2, thus simulating the effect of oblique light at dawn and dusk. Alternatively, the reflector 3 can be set non-parallel to the Rayleigh scattering light-transmitting plate 2. By tilting the reflector 3 at a certain angle, the light emitted by the light source 4 can be reflected by the reflector 3 and then perpendicularly incident on the Rayleigh scattering light-transmitting plate 2, thus simulating the effect of direct midday light. Of course, the lamp housing 1 can also be equipped with two reflectors 3 simultaneously: one parallel to the Rayleigh scattering light-transmitting plate 2 and the other tilted at a certain angle. This, combined with the movement of the light source 4, allows the light emitted by the lamp to possess both direct and oblique characteristics, thereby further enhancing the dynamic effect.

[0029] Preferably, the reflector 3 and the lamp housing 1 can also be connected by an electric adjustment bracket. The electric adjustment bracket is used to change the angle between the reflector 3 and the Rayleigh scattering light-transmitting plate 2. In this way, when only one reflector 3 is set, the tilt angle of the reflector 3 can be changed by the electric adjustment bracket. Combined with the translation drive component 5 to move the light source 4, the light emitted by the lamp can be more varied and achieve a more realistic dynamic effect.

[0030] Specifically, the electrically adjustable bracket uses a commercially available prefabricated bracket, and its specific structure will not be described in detail here.

[0031] like Figures 2 to 5 As shown, preferably, the light source 4 is a long strip of LED light or a circular LED light.

[0032] As mentioned above, the light source 4 of this lamp can be a long strip of LED light, which can achieve a more uniform illumination effect. Alternatively, the light source 4 can also be a circular LED light, which can make the light at the light outlet 11 form a blurred bright spot, thereby simulating the shape of the sun.

[0033] Specifically, the circular LED light is a COB LED light.

[0034] Preferably, when the light source 4 is a circular LED light, the center line of the light source 4 is aligned with the center line of the Rayleigh scattering light-transmitting plate 2, or the light source 4 is offset to one side of the Rayleigh scattering light-transmitting plate 2. In this way, setting the circular LED light in the center or offset to one side can better simulate the specific position of the sun and make the natural light effect more realistic.

[0035] Preferably, a rotating mechanism is also connected between the slider 54 and the light source 4. The rotating mechanism is used to drive the light source 4 to rotate and change the light emission angle. In this way, by dynamically adjusting the light emission angle of the light source 4 through the rotating mechanism, the dynamic effect of the light can be further increased, and the lamp can simulate a more realistic natural dynamic light effect.

[0036] Specifically, the rotating mechanism is a commercially available finished product, and its specific structure will not be described in detail here.

[0037] As stated above, this case protects a lighting fixture that can simulate natural dynamic lighting, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
