Technical Field

[0001] The present application relates to the field of lighting, and in particular to a lighting device. Background Art

[0002] With the development of society, people pay more and more attention to the outer packaging of various products in their lives, and the same is true for wine bottles. The shapes of wine bottles are becoming more and more exquisite, and the beauty gives wine bottles a sense of art. However, after drinking, most people still directly discard the wine bottles. This not only wastes resources, but also may break during the process of garbage transportation and disposal, thereby injuring people. Therefore, it is necessary to reuse the exquisite empty wine bottles.

[0003] For lamps, especially table lamps, for example lamps on tables or dining tables in restaurants (often in addition to or instead of candles) or lamps in the private sector, high demands are made with regard to design, light quality, light color and glare freedom. Summary of the invention

[0013] Furthermore, the ratio of the height of the light-distributing cover to the height of the lampshade is less than 1, and preferably, the ratio of the height of the light-distributing cover to the height of the lampshade is 1:(2-4).

[0016] Furthermore, the axis of the light-distributing cover coincides with the axis of the lampshade.

[0017] Further, the first lighting assembly is located at the center of the top of the lampshade; or

[0019] Furthermore, the light transmittance of the lampshade is 50%-90%; the light transmittance of the light-distributing cover is 50%-90%.

[0020] Furthermore, the connecting component extends into the opening of the light-distributing cover along a partial axial area thereof, and the portion of the connecting component that does not extend into the light-distributing cover extends along the axis of the lampshade in a direction away from the top of the lampshade.

[0021] The ratio of the equivalent diameter of the end of the connecting component away from the first lighting component to the equivalent diameter of the end of the lampshade close to the guide component is less than or equal to 1, preferably (1-15):15, and more preferably (7-15):15.

[0033] The following is a description of the exemplary embodiments of the present application, including various details of the embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0034] like Figure 1 As shown, the present application provides a lighting device, which includes a lampshade 1, a light-distributing cover 2, a connecting component and a guiding component 6.

[0035] A first lighting assembly 5 is arranged inside the lampshade 1 and on the top of the lampshade 1;

[0036] The light-distributing cover 2 is disposed in the lampshade 1, and the light-distributing cover 2 and the top of the lampshade 1 form a receiving space, and the first lighting assembly 5 is located in the receiving space;

[0037] One end of the connecting component is connected to the light-homogenizing cover 2 , and the other end thereof is detachably connected to the guiding component 6 .

[0038] A second lighting assembly is provided at one end of the connecting assembly facing the guiding assembly 6 .

[0039] In the lighting device described in the present application, since the first lighting component 5 is arranged in the accommodating space formed by the light-distributing cover 2 and the lampshade 1, the light emitted by the first lighting component 5 is evenly transmitted through the light-distributing cover 2 and the lampshade 1, thereby reducing the glare effect, and the light emitted by the second lighting component is evenly transmitted along the axial direction of the guide component 6. The light emitted by the first lighting component 5 through the light-distributing cover 2 and the lampshade 1 and the light emitted by the second lighting component through the guide component 6 form a special atmosphere. For example, when the end of the guide component 6 away from the second lighting component is inserted into the bottle mouth of a wine bottle, the light of the second lighting component is transmitted into the wine bottle through the guide component 6, thereby forming a special atmosphere with the light emitted by the first lighting component 5 through the light-distributing cover 2 and the lampshade 1.

[0040] In the present application, the light-distributing cover 2 is a structure with openings at both ends, and the radial size of the light-distributing cover 2 gradually decreases from the opening at one end connected to the top of the lampshade 1 to the opening at the other end connected to the connecting component.

[0041] The light-uniform cover 2 is used to shield the first lighting assembly 5 and its related circuits, and at the same time plays the role of diffusing and evenly distributing the light, thereby beautifying the lighting effect of the entire lampshade 1 .

[0042] Specifically, the outer contour of the light-homogenizing cover 2 may be conical, conical or hemispherical.

[0043] The axis of the light-distributing cover 2 passes through openings at both ends, and the openings at both ends are respectively a first opening and a second opening, the first opening is an opening at one end connected to the top of the lampshade 1, and the second opening is an opening at one end connected to the connecting assembly. The radial dimension of the light-distributing cover 2 gradually decreases from the first opening to the second opening.

[0044] In some embodiments, the equivalent diameter of the first opening of the light-evening cover 2 is equal to the equivalent diameter of the top of the lampshade 1 .

[0045] In some embodiments, the equivalent diameter of the first opening of the light-evening cover 2 is smaller than the equivalent diameter of the top of the lampshade 1 .

[0046] Specifically, the angle θ between the shortest connecting line on the openings at both ends of the light-distributing cover 2 and the axis of the light-distributing cover 2 is 10°-80°, preferably 15°-60°. For example, it can be 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, etc. Such a design is adopted to make the light emitted by the first lighting assembly 5 evenly transmitted, reducing the glare effect.

[0047] Specifically, the ratio of the height of the light-distributing cover 2 to the height of the lampshade 1 is less than 1, and preferably the ratio of the height of the light-distributing cover to the height of the lampshade is 1:(2-4), for example, it can be 1:2, 1:2.5, 1:3, 1:3.5, 1:4, etc.

[0048] Herein, the height of the light-distributing cover 2 is the length of the light-distributing cover 2 along its axial direction, and the height of the lampshade 1 is the length of the lampshade 1 along its axial direction.

[0049] The height of the light homogenizing cover 2 is 10-80 mm, preferably 20-50 mm, for example, 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, etc.

[0050] The height of the lampshade 1 is 55-200mm, preferably 80-150mm, for example, it can be 55mm, 60mm, 65mm, 70mm, 80mm, 90mm, 100mm, 110mm, 112mm, 115mm, 120mm, 125mm, 130mm, 135mm, 140mm, 145mm, 150mm, 160mm, 170mm, 180mm, 190mm, 200mm, etc.

[0051] Specifically, the shortest distance L between the connection between the light-distributing cover 2 and the top of the lampshade 1 and the first lighting component 5 is greater than or equal to 2 mm, preferably greater than or equal to 5 mm, and further preferably 5-30 mm, that is, the shortest distance L from the edge of the first opening of the light-distributing cover 2 to the first lighting component 5 is greater than or equal to 5 mm, preferably 5-30 mm, for example, it can be 2 mm, 3 mm, 4 mm, 5 mm, 8 mm, 10 mm, 12 mm, 14 mm, 16 mm, 18 mm, 20 mm, 22 mm, 24 mm, 26 mm, 28 mm, 30 mm, etc. When L is too large, the positions of the multiple first lighting components 5 will be too close together, and the multiple first lighting components 5 cannot evenly distribute and illuminate the lampshade 1. When L is too small, the multiple first lighting components 5 will be infinitely close to the outer wall of the lampshade 1, which is easy to produce high-brightness light spots on the outer wall of the lampshade 1, thereby affecting the lighting effect.

[0052] Specifically, the ratio L0 of the shortest distance between the connection between the light-evening cover and the top of the lampshade and the first lighting assembly to the equivalent radius of the top of the lampshade is less than 1, preferably L0 is greater than or equal to 1:10, and more preferably (5-30):50.

[0059] Specifically, the light transmittance of the lampshade 1 and the light-distributing cover 2 is 50%-90%, preferably 60%-80%; the light transmittance of the light-distributing cover 2 may be the same as or different from the light transmittance of the lampshade 1 .

[0060] If the light transmittance of the light-evening cover 2 is too low, the light emitted by the first lighting component 5 will be very dim. If it is too high, it will be close to the transparency of glass, and the components inside the lampshade 1 can be seen, and the position of the first lighting component 5 and the light emitted by the first lighting component 5 can be clearly seen, which will lose the functional light effect and beauty of the product.

[0061] If the light transmittance of the lampshade 1 is too low, the light emitted by the first lighting component 5 will be very dim. If it is too high, it will be close to the transparency of glass, and the components inside the lampshade 1 can be seen. The position of the light emitting cover 2, the position of the first lighting component 5, and the light emitted by the first lighting component 5 can all be clearly seen, which will lose the functional light effect and beauty of the product.

[0062] The light transmittance of the lampshade 1 can be 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90% and the like.

[0063] The light transmittance of the light homogenizing cover 2 can be 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90% and the like.

[0064] Herein, the light transmittance is the percentage of the light flux passing through a transparent or translucent body to the incident light flux thereof, which is measured by a spectrophotometer, a light transmittance meter, a haze meter or an illuminometer.

[0065] In some embodiments, the surface of the lampshade 1 may be a frosted surface, so that the light emitted by the first lighting assembly can be transmitted evenly.

[0075] In some embodiments, the equivalent diameter of the second end A of the first connecting portion 3 is smaller than the equivalent diameter of the first end B of the second connecting portion 4, so that there is sufficient space in the second connecting portion 4 for arranging functional components such as a battery module and a second circuit board; at the same time, the smaller equivalent diameter of the first connecting portion 3 is also beneficial for the light emitted by the first lighting component 5 to have appropriate space for diffusion.

[0091] There is also an annular groove in the connecting port, and the second lighting component is located in the annular groove. The height of the annular groove is slightly higher than the end of the second lighting component close to the guide component 6, so that the guide component 6 does not directly contact the second lighting component, thereby reducing damage to the second lighting component and the impact on the light effect of the second lighting component.

[0109] The locking assembly is sleeved on the outer circumference of the guiding assembly 6 .

[0110] The locking component is an elastic kit, a snap-fit ​​component, a magnetic component and / or a threaded pipe fitting.

[0111] In some embodiments, the locking assembly is an elastic kit, which can be a rubber ring made of rubber material, a partial area of ​​which is sleeved on the outer circumference of the portion of the guide assembly 6 extending into the connecting port, so that one end of the guide assembly 6 can be firmly inserted into the connecting port.

The locking component is arranged on the guide component 6, and the fixing component is arranged on the second connecting portion 4. When a partial area of ​​the guide component 6 is inserted into the connecting port, the locking component is snapped onto the fixing component.

[0114] In some embodiments, when the locking assembly is a hollow tubular structure, its end close to the second lighting assembly has a blocking portion that surrounds the end and extends toward the center of the tubular structure, and the equivalent inner diameter of the blocking portion is smaller than the equivalent inner diameter of the tubular structure. Such a design makes it difficult for the guide assembly 6 to extend out of the locking assembly, thereby protecting the second lighting assembly and reducing damage caused by contact with the guide assembly 6.
