Description

Technical Field

[0001] This application relates to the field of lighting, specifically to a lighting device. Background Technology

[0002] With the development of society, people are paying more and more attention to the packaging of various products in their lives, and wine bottles are no exception. The shapes of wine bottles are becoming more and more exquisite, and their beauty gives them the feel of works of art. However, after drinking the wine, most people still throw the wine bottles away directly. This not only wastes resources, but may also break during the garbage transportation and disposal process, thus causing personal injury. Therefore, it is necessary to make beautiful empty wine bottles reusable.

[0003] For lamps, especially table lamps, such as those on dining tables or sideboards in restaurants (usually in addition to or as a substitute for candles) or lamps in private settings, there are high requirements in terms of design, light quality, color temperature, and glare prevention. Utility Model Content

[0015] The ratio L0 of the shortest distance between the connection point of the light diffuser and the top of the lampshade and the first lighting component and 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.

[0016] Furthermore, the axis of the light diffuser coincides with the axis of the lampshade.

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

[0020] Furthermore, a portion of the connecting assembly extends into the opening of the light diffuser along its axial direction, and the portion of the connecting assembly not extending into the light diffuser 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 lampshade near the guide component is less than or equal to 1, preferably (1-15):15, more preferably (7-15):15.

[0022] Furthermore, the second lighting component is located at the center of the end of the connecting component away from the top of the lampshade; or

[0033] The following description provides exemplary embodiments of this application, including various details to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0034] like Figure 1 As shown, this application provides a lighting device, which includes a lampshade 1, a diffuser 2, a connecting component, and a guiding component 6.

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

[0036] The light diffuser 2 is disposed inside the lampshade 1, and the light diffuser 2 and the top of the lampshade 1 form a receiving space, and the first lighting component 5 is located in the receiving space;

[0037] One end of the connecting component is connected to the light distribution mask 2, and the other end is detachably connected to the guiding component 6.

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

[0039] The lighting device described in this application, since the first lighting component 5 is disposed within the receiving space formed by the light diffuser 2 and the lampshade 1, the light emitted by the first lighting component 5 is uniformly transmitted through the light diffuser 2 and the lampshade 1, thereby reducing the glare effect. Moreover, the light emitted by the second lighting component is uniformly transmitted along the axial direction of the guide component 6. The light emitted by the first lighting component 5 through the light diffuser 2 and the lampshade 1 and the light transmitted 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 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 diffuser 2 and the lampshade 1.

[0040] In this application, the light diffuser 2 has a structure with openings at both ends. From the opening at the end that connects to the top of the lampshade 1 to the opening at the end that connects to the connecting assembly, the radial dimension of the light diffuser 2 gradually decreases.

[0041] The diffuser 2 is used to shield the first lighting component 5 and its related circuits, while also serving to diffuse and even out the light, thus enhancing the lighting effect of the entire lampshade 1.

[0042] Specifically, the outer contour of the light distribution mask 2 can be conical, frustum-shaped, or hemispherical.

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

[0044] In some embodiments, the equivalent diameter of the first opening of the diffuser 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 diffuser 2 is smaller than the equivalent diameter of the top of the lampshade 1.

[0046] Specifically, the angle θ between the shortest connecting line at both ends of the light-diffusing cover 2 and the axis of the light-diffusing 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. This design ensures that the light emitted by the first lighting component 5 is transmitted evenly, reducing glare.

[0047] Specifically, the ratio of the height of the light distribution mask 2 to the height of the lampshade 1 is less than 1. Preferably, the ratio of the height of the light distribution mask to the height of the lampshade is 1:(2-4), such as 1:2, 1:2.5, 1:3, 1:3.5, 1:4, etc.

[0048] In this document, the height of the light diffuser 2 is the length of the light diffuser 2 along its axial direction, and the height of the lampshade 1 is the length of its axial direction.

[0049] The height of the light distribution mask 2 is 10-80mm, preferably 20-50mm, for example, it can be 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, etc.

[0050] The height of the lampshade 1 is 55-200mm, preferably 80-150mm, and can be, for example, 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 point of the light diffuser 2 and the top of the lampshade 1 and the first lighting component 5 is greater than or equal to 2mm, preferably greater than or equal to 5mm, and more preferably 5-30mm. That is, the shortest distance L from the edge of the first opening of the light diffuser 2 to the first lighting component 5 is greater than or equal to 5mm, preferably 5-30mm. For example, it can be 2mm, 3mm, 4mm, 5mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 24mm, 26mm, 28mm, 30mm, etc. When L is too large, it will cause the positions of the multiple first lighting components 5 to be too close together, and the multiple first lighting components 5 cannot evenly 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 will easily 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 point of the light diffuser and the top of the lampshade and the first lighting component 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. For example, it can be 5:50, 8:50, 10:50, 12:50, 14:50, 16:50, 18:50, 20:50, 22:50, 24:50, 26:50, 28:50, 30:50, etc.

[0053] Specifically, the axis of the light diffuser 2 coincides with the axis of the lampshade 1.

[0054] In this application, the first lighting component 5 is located at the center of the top of the lampshade 1, or the first lighting component 5 surrounds the center of the top of the lampshade 1 in a discrete or continuous manner.

[0055] The number of the first lighting components 5 can be one or more, for example, one, two, three, four, five, six, seven, etc. The specific number can be determined according to actual needs. When there are multiple first lighting components 5, the multiple first lighting components 5 can be of the same type of lamp or different types of lamp.

[0056] The first lighting component 5 can be an LED light bead.

[0057] In some embodiments, the number of the first lighting components 5 is 6, and the 6 equally spaced first lighting components 5 are arranged around the center of the top of the lampshade 1.

[0058] In some embodiments, the number of the first lighting components 5 is one, and the first lighting component 5 is located at the center of the top of the lampshade 1.

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

[0060] If the light transmittance of the light diffuser 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 all the internal components of the lampshade 1 will be visible. The location of the first lighting component 5 and the light emitted by the first lighting component 5 will be clearly visible, thus losing the product's functional lighting effect and aesthetic appeal.

[0061] If the light transmittance of the lampshade 1 is too low, the light displayed 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 all the internal components of the lampshade 1 will be visible. The location of the light diffuser 2, the location of the first lighting component 5, and the light emitted by the first lighting component 5 will all be clearly visible, thus losing the product's functional lighting effect and aesthetic appeal.

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

[0063] The transmittance of the light-diffusing mask 2 can be 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, etc.

[0064] In this document, transmittance is the percentage of luminous flux passing through a transparent or translucent body relative to its incident luminous flux. It is measured using a spectrophotometer, transmittance meter, haze meter, or illuminance meter.

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

[0066] In some embodiments, the lampshade 1 can be a multi-layered structure, which can be prepared by 3D printing technology or injection molding process.

[0067] In some embodiments, the surface of the light diffuser 2 can be a frosted surface, so that the light emitted by the first illumination component can be transmitted evenly.

[0068] In some embodiments, the light-diffusing mask 2 can be a multi-layered structure, which can be prepared by 3D printing technology or injection molding process.

[0069] Specifically, the device further includes a first circuit board, on which the first lighting component 5 is disposed and electrically connected, and the first circuit board is disposed at the center of the top of the lampshade 1.

[0070] In this application, the connecting component includes a first connecting part 3 and a second connecting part 4. The first connecting part 3 is connected to the first connecting part 4. The first connecting part 3 has a first end A and a second end A along its axial direction. The second connecting part 4 has a first end B and a second end B along its axial direction. The second end A of the first connecting part 3 is connected to the first end B of the second connecting part 4.

[0071] The outer contour of the first connecting part 3 is cylindrical, prismatic, frustum-shaped or frustum-shaped.

[0072] The outer contour of the second connecting part 4 is cylindrical, prismatic, frustum-shaped or prismatic.

[0073] The outer contour of the first connecting part 3 and the outer contour of the second connecting part 4 may be the same or different.

[0074] The equivalent diameter of the second end A of the first connecting part 3 is less than or equal to the equivalent diameter of the first end B of the second connecting part 4.

[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 enough space in the second connecting portion 4 to accommodate functional components such as the battery module and the second circuit board; at the same time, the smaller equivalent diameter of the first connecting portion 3 also helps to allow the light emitted by the first lighting component 5 to have adequate space to diffuse.

[0076] In some embodiments, the outer contour of the first connecting part 3 is cylindrical with a diameter of R1, and the outer contour of the second connecting part 4 is cylindrical with a diameter of R2, where R2 is greater than R1.

That is, the connecting component extends into the opening of the light diffuser 2 along its axial direction, and the portion of the connecting component that does not extend into the light diffuser 2 extends along the axis of the lampshade 1 toward the direction away from the top of the lampshade 1.

[0081] In some embodiments, the second end B of the second connecting part 4 is located inside the lampshade 1, and the height difference between the second end B of the second connecting part 4 and the end of the lampshade 1 away from the first lighting component 5 is h1, where h1 is greater than 0.

[0082] In some embodiments, the second end B of the second connecting portion 4 is flush with the end of the lampshade 1 away from the first lighting component 5.

[0083] In some embodiments, the second end B of the second connecting part 4 extends out of the lampshade 1, and the length of the portion of the second end B of the second connecting part 4 extending out of the lampshade 1 can be determined according to actual needs.

[0084] Specifically, the ratio of the equivalent diameter of the second end B of the second connecting portion 4 to the equivalent diameter of the end of the lampshade 1 furthest from the first lighting component 5 is less than or equal to 1, preferably (1-15):15, more preferably (7-15):15, that is, the ratio of the equivalent diameter of the end of the connecting component furthest from the first lighting component 5 to the equivalent diameter of the end of the lampshade 1 closest to the guide component 6 is less than or equal to 1, preferably (1-15):15, more preferably The ratio is (7-15):15, for example, it can be 1:15, 2:15, 3:15, 4:15, 5:15, 6:15, 7:15, 7.5:15, 8:15, 8.5:15, 9:15, 9.5:15, 10:15, 10.5:15, 11:15, 11.5:15, 12:15, 12.5:15, 13:15, 13.5:15, 14:15, 14.5:15, 15:15, etc.

[0085] Specifically, the second lighting component is located at the center of the second end B of the second connecting portion 4; or the second lighting component surrounds the center of the second end B of the second connecting portion 4 in a discrete or continuous manner; that is, the second lighting component is located at the center of the end of the connecting component away from the top of the lampshade 1; or the second lighting component surrounds the center of the end of the connecting component away from the top of the lampshade 1 in a discrete or continuous manner.

[0086] The number of the second lighting components can be one or more, for example, one, two, three, four, five, six, seven, etc., and the specific number can be determined according to actual needs. When there are multiple second lighting components, the multiple second lighting components can be of the same type of lamp or different types of lamps.

[0088] In some embodiments, the number of the second lighting components is six, and the six equally spaced second lighting components surround the center of the second end B of the second connecting portion 4.

[0089] In some embodiments, the number of the second lighting components is one, and the second lighting component is located at the center of the second end B of the second connecting portion 4.

[0090] Specifically, the connecting component also has a connection port surrounding the second lighting component, that is, the second end B of the second connecting part 4 has a connection port surrounding the second lighting component and protruding from the surface where the second lighting component is located. The guiding component 6 extends into the connection port and connects with the connecting component. This design is intended to guide the light from the second lighting component out through the guiding component 6.

[0091] The connection port also has an annular groove, in which the second lighting component is located. The height of the annular groove is slightly higher than the end of the second lighting component that is closer 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 efficiency of the second lighting component.

[0092] The inner contour of the connection port is adapted to the shape of the guide component 6, and the equivalent diameter of the inner contour of the connection port is slightly larger than the equivalent outer diameter of the guide component 6, so that the guide component 6 can be tightly inserted into the connection port.

[0094] In some embodiments, the inner contour of the connection port is cylindrical, the guide component 6 is cylindrical, and the inner diameter of the inner contour of the connection port is slightly larger than the outer diameter of the guide component 6.

Further, the second circuit board is electrically connected to the battery module via a first wire, and the second wire passes through the first connecting portion 3 and is electrically connected to the first circuit board.

[0098] In some embodiments, the battery module includes a battery compartment in which a removable and replaceable battery can be disposed.

[0099] In some embodiments, the battery module is fixed within the first connecting portion 3, and the battery module has a recyclable battery.

[0100] Specifically, in the battery-free version, the first connecting part 3 does not have a battery module, while the second connecting part 4 is provided with a connecting module. The connecting module is connected to an external power source via wires, and the connecting module is connected to the first circuit board and the second circuit board via wires.

[0101] Specifically, the device also includes a switch, which is disposed on the top of the lampshade 1 and is electrically connected to the battery module / connection module, the first lighting component 5 and the second lighting component.

[0102] Specifically, the outer wall of the guide component 6 has a frosted structure, and the light transmittance of the outer wall of the guide component 6 is 30% to 60%, for example, it can be 30%, 35%, 40%, 45%, 50%, 55%, 60%, etc.

[0103] The light transmittance of the guide component 6, both inside and at both ends of the axis, is 60%-90%. For example, it can be 60%, 65%, 70%, 75%, 80%, 85%, 90%, etc.

[0105] The guide component 6 can be made of PMMA acrylic, PC, PP plastic, glass, etc. Its length can be any value from 2cm to 50cm, for example, 2cm, 3cm, 4cm, 5cm, 6cm, 7cm, 8cm, 9cm, 10cm, 15cm, 20cm, 25cm, 30cm, 35cm, 45cm, 50cm, etc., including but not limited to these. The length of the guide component 6 can be any value, which can be specifically determined according to actual needs.

[0106] The material of the lampshade 1 can be PMMA acrylic, PC, PP plastic, glass, etc.

[0107] The material of the light-diffusing mask 2 can be PMMA acrylic, PC, PP plastic, glass, etc.

[0108] Specifically, the device further includes a locking component, and the guide component 6 is connected to the connection component via the locking component.

[0109] The locking component is fitted around the outer periphery of the guide component 6.

[0110] The locking components are elastic fittings, snap fasteners, magnetic components, and / or threaded fittings.

[0111] In some embodiments, the locking component is an elastic sleeve, which may be a rubber ring made of rubber material, with a portion of its area fitted around the outer periphery of the portion of the guide component 6 that extends into the connection port, thereby allowing one end of the guide component 6 to be securely inserted into the connection port.

[0112] In some embodiments, the locking component is a threaded pipe fitting, which is a plastic threaded pipe with external threads. A portion of the threaded pipe fitting is sleeved around the outer periphery of the portion of the guide component 6 that extends into the connection port, thereby allowing one end of the guide component 6 to be securely inserted into the connection port.

[0113] In some embodiments, the locking component is a snap-fit ​​element, which includes a fixing element and a locking element. The locking element is disposed on the guide component 6, and the fixing element is disposed on the second connecting part 4. When a portion of the guide component 6 is inserted into the connecting port, the locking element is fastened to the fixing element.

[0114] In some embodiments, when the locking component is a hollow tubular structure, it has a blocking portion around the end near the second lighting component and extending toward the center of the tubular structure. The equivalent inner diameter of the blocking portion is smaller than the equivalent inner diameter of the tubular structure. This design makes it difficult for the guide component 6 to extend out of the locking component, thereby protecting the second lighting component from damage caused by contact with the guide component 6.

[0115] Example

[0116] Unless otherwise specified, the experimental methods used in the following examples are conventional methods.

[0117] Unless otherwise specified, all materials and reagents used in the following examples are commercially available.

[0125] The lighting devices of Examples 7-11 differ from those of Example 1 in that the shortest distance L between the edge of the first opening of the diffuser 2 and the first lighting component 5 is different. All other parameters are the same. The parameters of this example are shown in Table 1.

[0126] The lighting devices in Examples 12-15 differ from those in Example 1 in that the light transmittance of the lampshade is different, while all other parameters are the same. The parameters of this example are shown in Table 1.

[0128] The UGR value was calculated using the CIE method for evaluating direct glare.

[0129] The calculation formula is Where L b Background brightness, unit cd / m² 2 L represents the luminance of the light-emitting part of the lamp in the direction of the observer's eyes, also measured in cd / m². 2 ω is the solid angle subtended by the luminous part of the lamp to the observer's eye; P is the position index of the lamp. The lower the UGR value, the less glare and the higher the visual comfort. UGR less than 16 is good visual comfort, UGR ≤ 19 is relatively ideal, and UGR > 19 is considered to have obvious glare.

[0130] Lighting Effect: Simulating a dimly lit bar environment at night, the lighting effect was tested with 100 people. The test results are shown in Table 2. The standard for "Excellent" is: the light emitted from the entire lampshade is very uniform, comfortable to the eye, neither glaring nor dim, and without any dark spots or bright spots. The standard for "Good" is: the light emitted from the entire lampshade is relatively uniform, with slightly lower brightness, comfortable to the eye, neither glaring nor dim, and without any dark spots or bright spots. The standard for "Poor" is: the light is clearly uneven to the naked eye, with obvious differences between bright and dim areas, and noticeable bright spots in the LEDs.

[0131] Ambient light is created by the light emitted by the first lighting component through the diffuser and lampshade, and the light transmitted by the second lighting component through the guide component, forming a special atmosphere. The quality of ambient light is determined by the light emitted by the first lighting component through the diffuser and lampshade and the light transmitted by the second lighting component through the guide component.

[0132] In this embodiment, the transmittance is measured using an illuminance meter.
