Description

Technical Field

[0001] This invention relates to the field of lighting technology, and more particularly to a shadowless lamp. Background Technology

[0002] A shadowless lamp is a type of lighting fixture designed to reduce or eliminate projected shadows. Existing shadowless lamps typically consist of multiple connecting rods and the lamp itself, with the connecting rods rotatably connected to the lamp. These connecting rods can rotate relative to each other. During use, the user can move the lamp's position using the connecting rods to avoid the angle that produces shadows, thus achieving a "shadowless" effect. However, this effect only shifts the shadow, not truly eliminates it, and the lamp still casts structural shadows on the connecting rods and other structural components. Furthermore, for lamps used to create ambient lighting or requiring multi-angle illumination where the position is fixed, the light emitted from these lamps often casts shadows on the connecting structures. These shadows cannot be eliminated, thus ruining the ambient effect or weakening the lighting effect, making them unsuitable for use. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a shadowless lamp that can reduce or eliminate shadows, thereby creating an atmosphere and lighting effect.

[0004] To solve the above-mentioned technical problems, the present invention provides a shadowless lamp, including a cover, a suspension component, a light-emitting component, and a light source component. The top of the cover is provided with a top surface. The two ends of the suspension component are a connecting end and a hanging end, respectively. The connecting end is connected to the top surface, and the hanging end is connected to the suspension body. The light-emitting component and the light source component are disposed on the top surface.

[0005] The light-emitting element is provided with a reflective part or a transmissive part, which surrounds the light source element and the connecting end. The connecting end is located at the central axis of the reflective part or the transmissive part.

[0006] The reflective part can generate reflected light rays parallel to the length direction of the suspension member.

[0007] Alternatively, the transmissive portion can generate scattered light rays that scatter outwards toward the outside of the suspension member.

[0008] As an improvement to the above solution, the light-emitting component includes a reflecting end and a fixed end. The fixed end is located at the bottom of the light-emitting component and fixed to the top surface. The reflecting end is located at the top of the light-emitting component. The reflecting part includes a concave arc-shaped reflecting surface. The reflecting surface extends from the inside of the fixed end to the inside of the reflecting end. The projected area of ​​the reflecting end on the top surface is smaller than the projected area of ​​the fixed end on the top surface.

[0009] As an improvement to the above solution, the light-emitting component is provided with a reflective groove, the opening of the reflective groove is parallel to the length direction of the suspension component, the reflective surface is arranged in a continuous annular shape and can surround the reflective groove, the reflective surface is a concave arc-shaped surface, and the curvature of the reflective surface gradually increases from the top surface toward the direction away from the top surface.

[0010] As an improvement to the above solution, the number of light sources is multiple and they are evenly arranged around the connection end, and both the light sources and the connection end are located within the reflective groove.

[0011] As an improvement to the above solution, the suspension body is located on the side of the shadowless lamp, the suspension member is inclinedly connected to the top surface, and the light-emitting member includes a lower light-emitting surface and an upper light-emitting surface that form the reflective groove. The lower light-emitting surface is located in the reflective groove on the side close to the suspension body, and the upper light-emitting surface is located in the reflective groove on the side away from the suspension body. The curvature of the lower light-emitting surface and the upper light-emitting surface gradually increases from the top surface toward the direction away from the top surface, and the curvature of the lower light-emitting surface is greater than that of the upper light-emitting surface.

[0012] As an improvement to the above solution, the transmissive part includes a transmissive surface, which is disposed on the side of the light-emitting part away from the top surface, and the transmissive surface gradually bulges outward from both sides toward the center to form an outwardly convex arc-shaped surface.

[0013] As an improvement to the above scheme, the transmission surface is arranged in a continuous annular shape. The transmission surface includes an inner light-transmitting surface and an outer light-transmitting surface that are smoothly connected. The inner light-transmitting surface is located inside the transmission surface, and the outer light-transmitting surface is located outside the transmission surface. The curvature of the inner light-transmitting surface gradually decreases from the inside to the outside, and the curvature of the outer light-transmitting surface gradually decreases from the outside to the inside.

[0014] As an improvement to the above solution, the light-emitting element includes a receiving groove, which is disposed on the side of the light-emitting element near the top surface. The light source element is disposed in the receiving groove. The receiving groove includes symmetrically arranged incident surfaces, and the curvature of the incident surfaces gradually increases and then gradually decreases from the end near the top surface to the end away from the top surface.

[0015] As an improvement to the above solution, the shadowless lamp also includes a baffle, which is disposed on the side of the light-emitting element, and the height of the baffle is greater than the height of the light-emitting element.

[0016] Implementing this invention has the following beneficial effects:

[0017] This invention relates to a shadowless lamp fixture comprising a cover, a suspension component, a light-emitting component, and a light source. The suspension component is connected to the top surface of the cover, and the light-emitting component is also located on the top surface of the cover. The light-emitting component illuminates the space above the top surface to create an atmospheric effect or enhance the illumination range. Because the light-emitting component has a reflective or transmissive portion, the reflective portion generates reflected light parallel to the length direction of the suspension component, thus preventing shadows from being cast on the sides of the suspension component. The transmissive portion generates scattered light that scatters outwards towards the outside of the suspension component, thereby reducing the light scattered to the sides of the suspension component and thus softening shadows. Therefore, this invention can reduce or eliminate cast shadows, which is beneficial for creating atmospheric and lighting effects. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0025] See Figures 1-3This invention discloses a shadowless lamp, including a cover 1, a suspension member 2, a light-emitting member 3, and a light source member 4. The top of the cover 1 is provided with a top surface 11. The two ends of the suspension member 2 are a connecting end 21 and a hanging end 22, respectively. The connecting end 21 is connected to the top surface 11, and the hanging end 22 is connected to a hanging body 6. The cover 1 is suspended from the hanging body 6 by the suspension member 2. The hanging body 6 can be a horizontally placed ceiling or a vertically erected wall. When connected to a horizontal surface such as a ceiling, the cover 1 remains horizontal. When connected to a vertical surface such as a wall, the cover 1 is tilted. The light-emitting element 3 and the light source element 4 are disposed on the top surface 11. The light source element 4 can illuminate the space above the top surface 11 to meet the user's needs for atmosphere creation or enhanced lighting. Without the light-emitting element 3, during illumination, the side light from the light source element 4 will illuminate the side of the hanging element 2, causing the hanging element 2 to cast a shadow on the hanging body 6. The light-emitting element 3 avoids this situation. The light-emitting element 3 has a reflective part 31 or a transmissive part 34, which surrounds the light source element 4 and the connecting end 21. The light emitted by the light source element 4 passes through the reflective part 31 or the transmissive part 34. Located at the central axis of the reflective part 31 or the transmissive part 34, after being processed by the light-emitting member 3, when the light emitted by the light source member 4 passes through the reflective part 31, the reflective part 31 can form reflected light parallel to the length direction of the suspension member 2. Since the light parallel to the length direction of the suspension member 2 will not be projected onto the side of the suspension member 2, the suspension member 2 will not be shadowed. When the light emitted by the light source member 4 passes through the transmissive part 34, the transmissive part 34 can form scattered light that scatters outward toward the outside of the suspension member 2. Since the light scatters outward, the light density illuminating the side of the suspension member 2 is reduced, thereby weakening the shadow formed by the suspension member 2 on the suspension body 6.

[0026] The beneficial effects of the embodiments of the present invention are as follows:

[0027] This invention provides a shadowless lamp fixture comprising a cover 1, a suspension member 2, a light-emitting member 3, and a light source 4. The suspension member 2 is connected to the top surface 11 of the cover 1, and the light-emitting member 3 is also located on the top surface 11 of the cover 1. The light-emitting member 3 illuminates the space above the top surface 11 to create an atmospheric effect or enhance the illumination range. Since the light-emitting member 3 has a reflective part 31 or a transmissive part 34, the reflective part 31 can generate reflected light parallel to the length direction of the suspension member 2, thus preventing shadows from being cast on the sides of the suspension member 2. The transmissive part 34 can generate scattered light scattering towards the outer side of the suspension member 2, thereby reducing the light scattered to the sides of the suspension member 2 and thus softening the shadows. Therefore, this invention can reduce or eliminate projected shadows, which is beneficial for creating atmospheric and lighting effects.

[0028] The first embodiment of the present invention discloses an implementation when the light-emitting element 3 is provided with a reflective part 31. Specifically, the light-emitting element 3 includes a reflective end 35 and a fixed end 36. The fixed end 36 is disposed at the bottom of the light-emitting element 3 and fixed to the top surface 11. The fixed end 36 is used for fixation. The reflective end 35 is disposed at the top of the light-emitting element 3. The reflective part 31 includes a concave arc-shaped reflective surface 311. The reflective surface 311 extends from the inner side of the fixed end 36 to the inner side of the reflective end 35, and can surround the light source element 4. Since the reflective surface 311 is a concave arc-shaped surface, in order to ensure that the side light emitted by the light source element 4 can be reflected by the reflective surface 311 into light parallel to the length direction of the suspension element 2, the projected area of ​​the reflective end 35 on the top surface 11 is smaller than the projected area of ​​the fixed end 36 on the top surface 11. The reflective surface 311 has a concave shape that is narrower at the top and wider at the bottom.

[0029] The light-emitting element 3 is a rotating body, and it has a reflective groove 32. The opening of the reflective groove 32 is parallel to the length direction of the suspension element 2. The bottom of the reflective groove 32 may or may not be through. In this embodiment, the bottom of the reflective groove 32 is through and fixed to the top surface 11, and the top surface 11 forms the bottom of the reflective groove 32. The connecting end 21 is located at the central axis of the reflective groove 32. The reflective surface 311 is arranged in a continuous annular shape and can surround the reflective groove 32. The reflective groove 32 can be formed by rotating the longitudinal section of the reflective surface 311 around the connecting end 21 by 360°. The reflective groove 32 can reflect the light generated by the light source element 4 in 360°. On the cross-section of the reflective surface 311, the curvature of the reflective surface 311 gradually increases from the top surface 11 toward the direction away from the top surface 11. Curvature reflects the degree of curvature of a curve at a certain point. Near the top surface 11, due to the small angle of incidence, the reflected light will deviate too much inward from the parallel line of the suspension member 2. Therefore, the curvature of the reflective surface 311 is small near the top surface 11. As it gets farther away from the top surface 11, the angle of incidence becomes larger. If the curvature is not changed, the reflected light will deviate too much outward from the parallel line of the suspension member 2. Therefore, in order to ensure that the reflected light is parallel to the length direction of the suspension member 2, the curvature needs to be increased. Thus, the curvature of the reflective surface 311 gradually increases from the top surface 11 toward the direction away from the top surface 11 to ensure that the reflected light is parallel to the length direction of the suspension member 2. The number of light source elements 4 is multiple and they are evenly arranged around the connection end 21. The light source element 4 is an illumination component that can emit light, such as an LED lamp bead. The light source element 4 and the connection end 21 are both located in the reflective groove 32. The light source element 4 is symmetrically arranged around the center of the connection end 21. Therefore, the light source element 4 can emit light evenly at all angles, avoiding biased reflected light.

[0030] See Figure 4The second embodiment of the present invention discloses an implementation method when the shadowless lamp is suspended at an angle. Specifically, the suspension body 6 is located on the side of the shadowless lamp, and the suspension member 2 is inclinedly connected to the top surface 11. At this time, the suspension member 2 and the top surface 11 form an inclined angle. Under this condition, reflected light will irradiate the side of the suspension member 2, thereby producing a shadow in the suspension body 6. To avoid this situation, the light emitting member 3 is adjusted as follows: the light emitting member 3 includes a lower light emitting surface 321 and an upper light emitting surface 322 that surround the reflective groove 32. The lower light emitting surface 321 is located in the reflective groove 32 on the side close to the suspension body 6, and the upper light emitting surface 322 is located in the reflective groove 32 on the side away from the suspension body 6. The curvature of the lower light emitting surface 321 and the upper light emitting surface 322 gradually increases from the top surface 11 toward the direction away from the top surface 11. Reflected light rays from the side closer to the suspension body 6 will deviate inward from the parallel line of the suspension member 2 and pass through the suspension member 2, while reflected light rays from the side farther from the suspension body 6 will deviate outward from the parallel line of the suspension member 2. At this time, the overall curvature of the lower light-emitting surface 321 is increased, and the overall curvature of the upper light-emitting surface 322 is decreased. The curvature of the lower light-emitting surface is greater than that of the upper light-emitting surface. The lower light-emitting surface 321 can correct the reflected light rays that deviate outward from the parallel line of the suspension member 2 to a position parallel to the suspension member 2, and the upper light-emitting surface 322 can correct the reflected light rays that deviate inward from the parallel line of the suspension member 2 to a position parallel to the suspension member 2, thereby achieving the effect of eliminating shadows.

[0031] See Figure 5 and Figure 6 The third embodiment of the present invention discloses an implementation when the light-emitting member 3 is provided with a transmission part 34. Specifically, the transmission part 34 includes a transmission surface 341, which is disposed on the side of the light-emitting member 31 away from the top surface 11. When the hanging member 2 is suspended on a horizontal surface such as the ceiling, the transmission surface 341 is located above the top surface 11. The transmission surface 341 gradually bulges outward from both sides towards the center to form an outwardly convex arc surface. The outwardly convex arc surface helps to form a convex lens so as to transmit the transmitted light at a scattering angle. The light-emitting member 3 is a rotating body, the connecting end 21 is disposed at the central axis of the light-emitting member 3, and the transmission surface 341 is arranged in a continuous annular shape.

[0032] The transmissive surface 341 includes a smoothly connected inner transmissive surface 3411 and an outer transmissive surface 3412. The inner transmissive surface 3411 is located inside the transmissive surface 341, and the outer transmissive surface 3412 is located outside the transmissive surface 341. The inner transmissive surface 3411 is close to the suspension member 2, and the outer transmissive surface 3412 is away from the suspension member 2. Because the arcuate surface of the transmissive surface 341 is formed by gradually convexing from both sides towards the center, light rays passing through the inner transmissive surface 3411 and the outer transmissive surface 3412 will diffuse in directions away from the transmissive surface 341. The light rays transmitted from the outer transmissive surface 3412 will not contact the suspension member 2; only the light rays transmitted from the inner transmissive surface 3411 will contact the side of the suspension member 2. However, due to the diffusion of the light rays transmitted from the inner transmissive surface 3411, the illumination intensity is weakened, and the distance between the light source 4 and the suspension member 2 is relatively narrow, thus reducing the projected shadow. The curvature of the inner transmissive surface 3411 gradually decreases from the inside to the outside, and the curvature of the outer transmissive surface 3412 gradually decreases from the outside to the inside. After the light source 4 emits light, the light passing through the inner light-transmitting surface 3411 has a greater curvature than the light source 2. Therefore, the refracted light has a better scattering effect, which disperses the light near the suspension member 2 as much as possible, reducing the shadow effect. Conversely, the light farther away from the suspension member 2 is weaker, so even with a smaller curvature, the projection effect on the suspension member 2 is smaller. Similarly, for the outer light-transmitting surface 3412, the light transmitted from it may reach adjacent suspension members 2, causing them to project their shadows. The closer to the adjacent suspension member 2, the greater its curvature, thus dispersing the refracted light as much as possible, reducing the projection effect on the adjacent suspension member 2.

[0033] The light-emitting element 3 includes a receiving groove 33, which is located on the side of the light-emitting element 3 near the top surface 11. The light source element 4 is disposed in the receiving groove 33, which is an annular groove. The light source element 4 is disposed within the receiving groove 33 and is centrally symmetrical with the light-emitting element 3. The receiving groove 33 includes symmetrically arranged incident surfaces 331. The light emitted by the light source element 4 enters from the symmetrical incident surfaces 331 on both sides and is refracted out from the inner light-transmitting surface 3411 and the outer light-transmitting surface 3412 respectively, forming a scattering effect. The curvature of the incident surface 331 gradually increases and then gradually decreases from the end near the top surface 11 to the end away from the top surface 11. The light emitted from the light source 4 is first refracted in the incident surface 331. The greater the curvature, the stronger the refraction effect. In order to further reduce the light projected onto the suspension member 2 or adjacent suspension member 2, the curvature of the surface located in the middle of the incident surface 331 is the largest, so it has a strong scattering effect. This causes the light to be weakened before it is refracted out from the inner light-transmitting surface 3411 and the outer light-transmitting surface 3412, thus avoiding excessive light density and reducing the projection produced by the suspension member 2.

[0034] The suspension member 2 is usually multiple. During the illumination of the light source 4, the light source 4 may cast lateral shadows on the adjacent suspension members 2. In the third embodiment, in order to further reduce the shadows on the adjacent suspension members 2, the shadowless lamp also includes a baffle 5. The baffle 5 is disposed on the side of the light emitting member 3. As needed, the baffle 5 can be disposed on one side of the light emitting member 3 or on multiple sides of the light emitting member 3. The height of the baffle 5 is greater than the height of the light emitting member 3 but less than the length of the suspension member 2. When the light transmitted from the inner light-transmitting surface 3411 shines out, the baffle 5 can block part of the light, thereby reducing the light illuminating the adjacent suspension members 2. Moreover, under the diffusion effect of the transmission surface 341, the illumination intensity of the light illuminating the adjacent suspension members 2 is weakened, thereby weakening or even eliminating the shadows generated by the adjacent suspension members 2.

[0035] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
