[0002] In daily life, as people's requirements for the quality of surrounding lighting environments continue to increase, lighting devices that can simulate the effects of natural sunlight are gradually gaining attention. Natural sunlight not only has the characteristics of high central brightness and concentrated light, but also is accompanied by a soft peripheral halo. This unique lighting effect can create a warm and comfortable visual experience, making sun lamps widely used in various scenarios such as indoor lighting, photography fill light, stage lighting, and psychological healing lighting.

[0003] Currently, commercially available lighting devices that simulate the sun typically use a single light source combined with simple lenses or reflective structures to converge and diffuse light. However, traditional sun simulation structures generally suffer from the following shortcomings: for example, insufficient light uniformity, difficulty in simultaneously achieving both concentrated central light and soft peripheral halo, resulting in a harsh, unlayered sun simulation effect. Furthermore, existing sun simulation devices are complex in structure, have high manufacturing and maintenance costs, and are prone to damage. Utility Model Content

[0038] See Figures 1 to 3 This utility model provides a sunlight simulation device 1, which is used to simulate the effect of sunlight, producing uniform sunlight with a halo, and can then be applied to the simulation effect of sunlight in fluorescent lamps and toys in daily life.

[0039] Furthermore, the sunlight simulation device 1 includes a lighting assembly 10 and a light guide plate 20. The lighting assembly 10 includes a first light source 11 and multiple second light sources 12, which are spaced apart circumferentially. The first light source 11 is located at the center of the multiple second light sources 12. The light guide plate 20 is attached to the lighting assembly 10, and a focusing tube 21 is fixedly mounted on the light guide plate 20. The axial extension direction of the focusing tube 21 is the same as the illumination direction of the first light source 11. The focusing tube 21 has light guide holes 211 extending through both ends along its axial direction. The first light source 11 is located at one end of the focusing tube 21, and the light from the first light source 11 is emitted outward along the light guide hole 211, so that the focusing tube 21 reflects and concentrates the light from the first light source 11 to form a bright spot at the center. The sunlight simulation device 1 also includes a light homogenizing assembly 30, which is disposed on one side of the lighting assembly 10 and homogenizes and softens the light, forming a halo around the central bright spot, thereby improving the simulation effect of sunlight and increasing the sense of layering. The sunlight simulation device 1 uses a focusing tube 21 to concentrate the light from the first light source 11, and uses a light-diffusing component 30 to diffuse the light from the surrounding second light source 12 and form a halo, thereby simulating the effect of sunlight. Furthermore, the sunlight simulation device 1 has a simple structure, which greatly reduces the cost.

[0040] The first light source 11 and the second light source 12 are used to simulate the central ray and the surrounding halo of sunlight, respectively. Multiple second light sources 12 surround to form an approximately circular structure, with the first light source 11 located at the center of the circular structure. The first ray is focused by the focusing tube 21 to form a bright spot, simulating the central bright spot of sunlight. The second light source 12 is homogenized by the light homogenizing component 30, thereby producing the effect of light gradually diverging from the center to the outside, so that the central ray bright spot combines with the surrounding soft light to form a layered effect, realizing the simulation effect of sunlight illumination.

[0041] Furthermore, the inner wall of the light guide hole 211 is provided with a smooth reflective surface to concentrate the reflected light. In this embodiment, the shape of the light guide hole 211 is the same as that of the focusing tube 21, both being cylindrical structures. The light guide hole 211 is located at the center of the focusing tube 21, and the axial direction of the light guide hole 211 is the same as that of the focusing tube 21. Since the propagation of light is divergent, a single light source will diffuse evenly along the hemisphere, mixing with the surrounding light and failing to form a bright core. This will result in an unclear outline of the sun in the simulation of sunlight. In this application, the focusing tube 21 is aligned with the first light source 11, and the light from the first light source 11 is located at one end of the light guide hole 211. The focusing tube 21 restricts the diffusion of the light from the first light source 11, allowing the light to only exit through the other end of the light guide hole 211, thereby forming a relatively clear and bright circular light spot at the exit end, achieving the effect of simulating the sun. Specifically, a reflective surface is provided on the inner wall of the light guide hole 211. The reflective surface is coated with a high reflectivity coating, such as a diffuse reflection coating of barium sulfate or magnesium oxide. The light entering the light guide hole 211 will undergo multiple diffuse reflections through the reflective surface. After multiple diffuse reflections, the light will be fully mixed in the focusing tube 21 to eliminate the problem of uneven brightness in the first light source 11 itself. This prevents glare from occurring at the light output end of the light guide hole 211 and ensures that the light is emitted along the axis of the light guide hole 211 without interfering with the surrounding light.

[0042] Furthermore, a light-shielding wall 22 protrudes from the side of the light guide plate 20 where the focusing tube 21 is located. The light-shielding wall 22 extends circumferentially along the edge of the light guide plate 20 and connects end to end. The light-shielding wall 22 is used to block the light from the second light source 12 from escaping outward along the edge of the light guide plate 20. The light-shielding wall 22 extends and closes along the edge of the light guide plate 20 to form an annular barrier. When the light from the second light source 12 shines, the light diffuses in all directions. When the light diffuses to the edge of the light guide plate 20, it is blocked by the light-shielding wall 22, resulting in multiple reflections. This allows the light to propagate only in front of the light guide plate 20, forming a uniform and soft halo, avoiding uneven brightness caused by external structural interference, and improving the purity of the halo.

[0043] Furthermore, the light guide plate 20 has multiple light-passing holes 23, which are aligned with the second light source 12 and are located within the enclosure of the light-shielding wall 22. In this embodiment, the second light source 12 is located on the side of the light guide plate 20 facing away from the focusing tube 21. The light-passing holes 23 penetrate the light guide plate 20 so that the light from the second light source 12 can pass through the light-passing holes 23 for illumination. The number of light-passing holes 23 is the same as the number of second light sources 12, and the light-passing holes 23 are arranged circumferentially around the focusing tube 21. All the light-passing holes 23 are located within the enclosure of the light-shielding wall 22, so that the light from the multiple second light sources 12 is all within the shielding range of the light-shielding wall 22. It can be understood that when the second light source 12 is located on the side of the light guide plate 20 where the focusing tube 21 is located, the light-passing holes 23 may not be provided.

[0044] Furthermore, the light guide plate 20 has a circular structure, and the focusing tube 21 is located at the center of the light guide plate 20. In this embodiment, the light guide plate 20 is circular to reflect a circular aperture, and multiple second light sources 12 are distributed circumferentially along the edge of the circular light guide plate 20. The focusing tube 21 is located at the center of the circular light guide plate 20 so that when the first light source 11 is directly opposite the end of the focusing tube 21, it is exactly at the center of the entire circular aperture, thereby ensuring that the simulated sun is located at the center of the simulated halo.

[0045] Furthermore, four second light sources 12 are provided, and the four second light sources 12 are arranged at equal intervals along the circumference of the light guide plate 20. In this embodiment, the second light sources 12 are evenly distributed along the circular light guide plate 20, so that the amount of light distributed in the same area is equal, thereby forming a uniform light illumination effect, making the formed halo complete and uniform. It can be understood that other numbers of second light sources 12 can also be provided, as long as each light source is equally distributed to ensure uniform light illumination.

[0046] Furthermore, the light-diffusing assembly 30 includes a light-diffusing sheet 31 that is attached to the light guide plate 20. The light-diffusing sheet 31 has a clearance hole 311 to avoid the light-concentrating tube 21. The light-diffusing sheet 31 covers the front of the plurality of second light sources 12 to form a halo. In this embodiment, the light-diffusing sheet 31 is a semi-transparent sheet of light-transmitting paper. The light-diffusing sheet 31 is disposed on the side of the light guide plate 20 where the light-concentrating tube 21 is located, and the light-diffusing sheet 31 covers the upper edge of the circumferentially enclosing light-shielding wall 22, so that the light-diffusing sheet 31 and the light guide plate 20 cover each other to form a light-diffusing space. The light homogenizer 31 completely covers the second light source 12. The light homogenizer 31 has a clearance hole 311 to avoid the focusing tube 21. The clearance hole 311 has the same cross-sectional shape as the focusing tube 21. One end of the focusing tube 21 passes through the clearance hole 311 so that the light from the first light source 11 is not blocked by the light homogenizer 31, thereby making the first light source 11 form a central bright spot. The light from the second light source 12 is scattered and homogenized after passing through the light homogenizer 31, mixing multiple spaced and discrete light spots into a uniform and soft circular halo. At the same time, the bright spot formed by the first light source 11 is located at the center of the circular halo, thus forming a halo around the bright spot of the first light source 11, so that the bright spot represents the sun and the surrounding circular halo represents the halo around the sun, thereby creating the effect of simulating sunlight.

[0047] Furthermore, the light-diffusing assembly 30 also includes a light-transmitting plate 32, which is disposed in front of the light guide plate 20 and located in the illumination path of the first light source 11 and the second light source 12. Along the light illumination direction, the light-transmitting plate 32 is located behind the light guide plate 20 and the light-diffusing plate 31. Light passes sequentially through the light guide plate 20, the light-diffusing plate 31, and the light-transmitting plate 32, allowing the light from the first light source 11 and the second light source 12 to pass through the light-transmitting plate 32 and illuminate the external environment. In this embodiment, the surface of the light-transmitting plate 32 is micro-frosted to scatter strong light, eliminate glare, and thus improve the comfort of the human eye when directly exposed to light. The light-transmitting plate 32 also serves a protective function to prevent external debris from damaging the lighting assembly 10.

[0048] Furthermore, the lighting assembly 10 also includes a control board 13, and the first light source 11 and the second light source 12 are LED beads embedded in the control board 13. In this embodiment, the control board 13 is connected to a power supply, so that the first light source 11 and the second light source 12 are powered through the control board 13. This power supply can be battery-powered or directly connected via a plug. The first light source 11 and the second light source 12 are LED beads, and the control board 13 adjusts the brightness of the first light source 11 and the second light source 12 to simulate the real-time dynamic changes in the light effect of sunlight to meet the needs of different scenarios. It can be understood that the control board 13 is a PCB board, and the first light source 11 and the second light source 12 are embedded in the control board 13 according to a preset arrangement, thereby simplifying the internal wiring, making the overall structure more compact, and saving space. It should be noted that the first light source 11 can be a high-brightness, high-color-temperature LED bead to simulate the bright core of the sun, and the second light source 12 can be an LED bead with a different color temperature than the first light source 11 to enhance the sense of layering of the light source effect.

[0049] refer to Figure 4 and Figure 5 This application discloses a liftable fluorescent lamp, which includes the aforementioned sunlight simulation device 1, lifting device 4, driving component 5, and housing 6. The sunlight simulation device 1 is mounted on the lifting device 4, and the driving component 5 drives the lifting device 4 to move, thereby moving the sunlight simulation device 1 up and down to simulate the rising and setting of the sun. The housing 6 is disposed outside the sunlight simulation device 1, the lifting device 4, and the driving component 5.

[0050] Specifically, the lifting device 4 includes a slide rail 41, a slider 42, and a sliding plate 43. The slide rail 41 extends vertically and has a sliding groove 411 for the slider 42 to slide. The sliding groove 411 extends vertically and the slider 42 slides vertically along the sliding groove 411. The sunlight simulation device 1 is fixedly installed on the slider 42 to drive the sunlight simulation device 1 to rise and fall.

[0051] Furthermore, the inner wall of the sliding groove 411 protrudes towards the center, so that the edge of the inner wall of the sliding groove 411 is clamped between the slider 42 and the sunlight simulation device 1, to prevent the slider 42 and the sunlight simulation device 1 from disengaging from the slide rail 41 during sliding. One end of the sliding plate 43 is connected to the slider 42, and when the sliding plate 43 moves up and down, it drives the slider 42 to slide up and down along the sliding groove 411.

[0052] The driving component 5 includes a drive motor 51 and gears. The gears are positioned between the drive motor 5 and the slide plate 43. The drive motor 5 drives the gears to rotate, thereby moving the slide plate 43. Specifically, in this embodiment, three gears are provided: a first gear 52, a second gear 53, and a third gear 54, for speed regulation. The drive end of the drive motor 51 is connected to the first gear 52 and drives it to rotate. The second gear 53 meshes with both the first gear 52 and the third gear 54, and the third gear 54 drives the slide plate 43 to move. The slide plate 43 has a laterally extending drive groove 431. The side of the third gear 54 has a drive post 541 that inserts into the drive groove 431, and the drive post 541 can move relative to the drive groove 431.

[0053] When the drive motor 51 starts, the first gear 52 drives the third gear 54 to rotate. At this time, the rotation path of the drive column 541 can be decomposed into horizontal movement and vertical movement. The drive column 541 moves horizontally within the drive groove 431. The vertical movement of the drive column 541 drives the vertical movement of the slide plate 43. In turn, the slide plate 43 drives the slider 42 to move vertically along the sliding groove 411, thereby realizing the lifting and lowering of the sunlight simulation device 1. Specifically, the user can control the drive motor 51 through the button.

[0054] The rising fluorescent lamp also includes an auxiliary light plate 7, which is located on the light-incident side of the light-transmitting plate 32. The light from the auxiliary light plate 7 passes through the light-transmitting plate 32, and the direction of the light from the auxiliary light plate 7 is consistent with the direction of the light from the sunlight simulation device 1, so as to simulate the brightness of the sky.

[0055] The housing 6 also contains an environmental component 61 located in the direction of sunlight simulation device 1 and used to simulate land and sea surfaces, so as to make the projected light effect more realistic.

[0056] The rising fluorescent lamp also includes a sound source component 8, which is used to emit different music and environmental simulation sounds to coordinate with the activation and rising and falling of the sunlight simulation device 1.

[0057] The rising fluorescent light also includes a control component 9, which is electrically connected to the sunlight simulation device 1 and the drive component 5. The control component 9 is used to control the brightness of the sunlight simulation device 1, the start of the drive motor 51, and the playback of the sound source component 8. In this embodiment, the control component 9 consists of multiple buttons and a circuit board. The circuit board is electrically connected to the above components. The multiple buttons correspond to multiple control modules on the circuit board. Users can switch between different functions by pressing the buttons.

[0058] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
