Description

Technical Field

[0001] This application relates to the field of lighting device technology, and in particular to a lamp. Background Technology

[0002] Traditional lighting fixtures mostly employ a single-sided light-emitting design, where light radiates directionally through only a single emitting surface. This design has significant limitations in certain scenarios: unidirectional light emission leads to uneven light distribution within the space, requiring multiple fixtures to be stacked to achieve uniform illumination, increasing installation costs and energy consumption. While some double-sided light-emitting fixture solutions exist in existing technologies, their implementation often relies on the back-to-back assembly of two independent light source modules, resulting in a significant increase in fixture thickness, structural redundancy, and low heat dissipation efficiency. Utility Model Content

[0003] This application provides a lighting fixture.

[0004] This application provides a lamp fixture, which includes a housing, a light source module, and a first light guide. The housing includes a main body, a first lampshade, and a second lampshade, which are respectively connected to opposite sides of the main body. The light source module is disposed within the housing and includes a first light-emitting element, a second light-emitting element, and a first controller. The first controller is electrically connected to the first and second light-emitting elements and is used to simultaneously control the operation of the first and second light-emitting elements. The first lampshade is opposite to the first light-emitting element to conduct light emitted by the first light-emitting element to the outside of the housing, and the second lampshade is opposite to the second light-emitting element to conduct light emitted by the second light-emitting element to the outside of the housing. The first light guide is disposed between the second lampshade and the second light-emitting element.

[0005] In some alternative examples, the first light guide includes a first light guide portion and a second light guide portion. The first light guide portion is disposed between the second lampshade and the second light-emitting element. The first light guide portion covers the light-emitting surface of the second light-emitting element. The second light guide portion is connected to the side of the first light guide portion away from the second light-emitting element and protrudes relative to the first light guide portion. The side of the second light guide portion away from the first light guide portion is exposed to the outside through the second lampshade.

[0006] In some alternative examples, the surface of the first light guide facing the second lampshade is covered with a first light-transmitting layer, the light transmittance of the first light-transmitting layer being less than the light transmittance of the first light guide.

[0007] In some alternative examples, the second lampshade is provided with a relief groove, and the side of the second light guide that is away from the first light guide protrudes to the outside through the relief groove. The side of the second light guide that protrudes to the outside is covered with a second light-transmitting layer, and the light transmittance of the second light-transmitting layer is less than the light transmittance of the second light guide.

[0008] In some alternative examples, the luminaire also includes a patterned diaphragm covering the second lampshade. The patterned diaphragm has a first light-emitting pattern area, and a portion of the light emitted from the second light-emitting element is emitted sequentially through the first light guide, the second lampshade, and the first light-emitting pattern area.

[0009] In some alternative examples, the first light guide portion has a light guide groove on the side facing the second light-emitting element, and the light guide groove is recessed relative to the surface of the first light guide portion.

[0010] In some optional examples, the light source module also includes a circuit board, a third light-emitting element, and a second controller. The first and second light-emitting elements are respectively connected to opposite sides of the circuit board, the third light-emitting element is connected to the side of the circuit board facing the second light-emitting element, and the second controller is electrically connected to the third light-emitting element to control the operation of the third light-emitting element. The housing also includes a third lampshade, which is opposite to the third light-emitting element to conduct light emitted by the third light-emitting element to the outside of the housing.

[0011] In some alternative examples, a third lampshade is inserted through the second lampshade and connected to the circuit board. The third lampshade has an inner cavity and covers the third light-emitting element through the inner cavity. The luminaire also includes a second light guide, which is disposed in the inner cavity and is disposed opposite to the third light-emitting element.

[0012] In some alternative examples, the third lampshade has a body with a second light-emitting pattern area opposite to the second light guide, the light transmittance of the second light-emitting pattern area being greater than that of the body, and the light emitted by the third light-emitting element is emitted sequentially through the second light guide and the second light-emitting pattern area.

[0013] In some alternative examples, the second light-emitting pattern area is a through hole connecting the inner cavity and the outside, and one end of the second light guide is inserted through the through hole and exposed to the outside.

[0014] In some alternative examples, the third lampshade is provided with a limiting part that is spaced apart from the circuit board; the luminaire also includes a light shield that is disposed between the limiting part and the circuit board and surrounds the third light-emitting element.

[0015] Compared to existing technologies, the lamp provided in this application, when in use, involves a first controller simultaneously controlling the operation of both the first and second light-emitting elements. Light emitted from the first light-emitting element is conducted from the first lampshade to the outside of the housing, while light emitted from the second light-emitting element is conducted via the first light guide to the second lampshade and then to the outside. The lamp provided in this application achieves bi-directional light emission using a single light source module controlled by the same controller. This single light source module avoids the structural redundancy and significant increase in lamp thickness caused by using two independent light sources, thus promoting lightweight design. Furthermore, the first and second lampshades are integrated on both sides of the light source module, resulting in a compact structure and high luminous efficiency. Attached Figure Description

Detailed Implementation

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0025] If certain terms are used in the specification and claims to refer to specific components, those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. The specification and claims do not distinguish components based on differences in name, but rather on differences in function. For example, the term "comprising" used throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to"; "generally" means that those skilled in the art can solve the technical problem and basically achieve the technical effect within a certain margin of error.

[0026] Please see Figure 1 This application provides a lamp 100, which can be installed in a building to provide lighting or decoration. For example, the lamp 100 can be used in living rooms, dining rooms, bedrooms and other places as decorative lighting to enhance the style of the space.

[0027] Please also refer to Figure 2 and Figure 3 In this embodiment, the lamp 100 may include a housing 10, a light source module 30, and a first light guide 50. The housing 10 may include a housing body 12, a first lampshade 14, and a second lampshade 16, with the first lampshade 14 and the second lampshade 16 respectively connected to opposite sides of the housing body 12. The light source module 30 is disposed inside the housing body 12 and may include a first light-emitting element 32, a second light-emitting element 34, and a first controller 36 (not shown in the figure). The first controller 36 is electrically connected to the first light-emitting element 32 and the second light-emitting element 34, and is used to simultaneously control the operation of the first light-emitting element 32 and the second light-emitting element 34. The first lampshade 14 is opposite to the first light-emitting element 32 to conduct light emitted by the first light-emitting element 32 to the outside of the housing 10, and the second lampshade 16 is opposite to the second light-emitting element 34 to conduct light emitted by the second light-emitting element 34 to the outside of the housing 10. The first light guide 50 is disposed between the second lampshade 16 and the second light-emitting element 34.

[0028] In use, the first controller 36 simultaneously controls the operation of the first light-emitting element 34 and the second light-emitting element 36. The light emitted by the first light-emitting element 34 is conducted from the first lampshade 14 to the outside of the housing 10, and the light emitted by the second light-emitting element 36 is conducted through the first light guide 50 to the second lampshade 16, and then through the second lampshade 16 to the outside. The lamp 100 provided in this application uses a single light source module 36 controlled by the same controller to achieve bi-sided light emission. The single light source module 36 avoids the structural redundancy and significant increase in the thickness of the lamp 100 caused by using two independent light sources, thus promoting the lightweighting of the lamp. Furthermore, the first lampshade 14 and the second lampshade 16 are integrated on both sides of the light source module 36, resulting in a compact structure and high luminous efficiency.

[0029] In this application, unless otherwise expressly specified or limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or merely surface contact. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] In this embodiment, the housing body 12 is used to install other structures of the lamp 10. This specification does not limit the specific shape of the housing body 12; the shape of the housing body 12 can be adaptively adjusted according to the required shape of the lamp 100. In this embodiment, the housing body 12 has a mounting cavity 121 that extends through both sides of the housing body 12 along its thickness direction. The light source module 30 is disposed within the mounting cavity 121. The first lampshade 14 and the second lampshade 16 are respectively connected to opposite sides of the housing body 12 to shield the mounting cavity 121.

[0031] In the description of this application, it should be understood that the terms "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "inside", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the purpose of simplifying the description of this application and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0032] The light source module 30 may further include a circuit board 31, which is mounted within the mounting cavity 121. The first light-emitting element 32 and the second light-emitting element 34 are respectively disposed on opposite sides of the circuit board 31 and are both electrically connected to the circuit board. This specification does not limit the specific types of the first light-emitting element 32 and the second light-emitting element 34. For example, the first light-emitting element 32 and the second light-emitting element 34 may include at least one of the following light sources: LED beads, lasers. As an example, the first light-emitting element 32 may include a plurality of LED beads spaced apart along the length of the circuit board 31 on one side of the circuit board 31, and the second light-emitting element 34 may include a plurality of LED beads spaced apart along the length of the circuit board 31 on the other side of the circuit board 31. A first controller 36 is disposed on the circuit board 31 and electrically connected to the circuit board 31, and simultaneously controls the operation of the first light-emitting element 32 and the second light-emitting element 34 through the circuit board 31.

[0033] The first lampshade 14 is connected to one side of the main housing 12 and is spaced apart from the first light-emitting element 32. For example, the first lampshade 14 can be snap-fitted into the main housing 12. The first lampshade 14 is made of a light-transmitting material, such as glass, plastic, polyester, or composite materials. The first lampshade 14 can be a transparent lampshade with high light transmittance or a semi-transparent lampshade with low light transmittance. In this embodiment, the first lampshade 14 is a milky white semi-transparent lampshade. For example, the first lampshade 14 can be made of milky white glass or milky white plastic; or the surface of the first lampshade 14 can be formed into a milky white semi-transparent effect by frosting, coating, or other methods. The milky white semi-transparent first lampshade 14 can soften the light, provide uniform illumination, and avoid glare. In some embodiments, the first lampshade 14 can be configured as an arc-shaped lampshade, which can effectively scatter light, reduce glare, and provide more uniform illumination.

[0034] In this embodiment, a first light guide 50 is disposed between the second lampshade 16 and the second light-emitting element 34, and is used to conduct the light emitted by the second light-emitting element 34 to the second lampshade 16. The first light guide 50 may include a first light guide portion 52 and a second light guide portion 54. The first light guide portion 52 is disposed between the second lampshade 16 and the second light-emitting element 34, and covers the light-emitting surface of the second light-emitting element 34. The second light guide portion 54 is connected to the side of the first light guide portion 52 away from the second light-emitting element 34 and protrudes relative to the first light guide portion 52. The side of the second light guide portion 54 facing away from the first light guide portion 52 is exposed to the outside through the second lampshade 16. The first light guide portion 52 and the second light guide portion 54 respectively conduct the light emitted by the second light-emitting element 34, forming two light-emitting areas, further enriching the light emission effect of the lamp 100.

[0035] In this application specification, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] The first light guide portion 52 is generally elongated and plate-shaped. It is connected to the main housing 12, for example, by snapping it against the inner wall of the main housing 12. The first light guide portion 52 may have a surrounding structure for snapping against the inner wall of the main housing 12. The circuit board 31 can be fixedly connected to the first light guide portion 52 by bolts. The first light guide portion 52 is stacked between the circuit board 31 and the second lampshade 34. The first light guide portion 52 and the circuit board 31 can be spaced apart to provide accommodating space for the second light-emitting element 34. Part of the light emitted by the second light-emitting element 34 can be conducted through the first light guide portion 52 to the second lampshade 34 and then diffused to the outside.

[0037] This specification does not limit the specific material of the first light guide 52. The first light guide 52 can be made of a light guide material with high transparency or a light guide material with low light transmittance. In this embodiment, the first light guide 52 is made of a transparent material with high light transmittance to facilitate the conduction of light to the second light guide 52. The surface of the first light guide 52 facing the second lampshade 34 is covered with a first light-transmitting layer 521, and the light transmittance of the first light-transmitting layer 521 is lower than that of the first light guide 52. The light emitted by the second light-emitting element 34 passes through the first light guide 52 and the first light-transmitting layer 521 and is emitted to the second lampshade 34. The first light-transmitting layer 521 improves the uniformity of the light emitted through the second lampshade 34. At the same time, the first light-transmitting layer 521 with low light transmittance can also block the second light-emitting element 34 inside the main housing 12, improving the overall aesthetics of the lamp 100. In this embodiment, the first light-transmitting layer 521 can be a semi-transparent coating applied to the surface of the first light guide portion 52, such as milky white paint or special coating. In other embodiments, the first light-transmitting layer 521 can also be milky white glass, milky white plastic, etc., stacked on the surface of the first light guide portion 52; or, the first light-transmitting layer 521 can also be a microstructure formed on the surface of the first light guide portion 52.

[0038] In this embodiment, the second light guide portion 54 is connected to the side of the second light guide portion 52 facing away from the circuit board 31. The second light guide portion 54 is also generally elongated, and is generally perpendicular to the first light guide portion 52. This specification does not limit the specific connection method between the first light guide portion 52 and the second light guide portion 54. For example, the first light guide portion 52 can be connected to the second light guide portion 54 by adhesive, or the second light guide portion 54 can be integrally formed with the first light guide portion 52 (e.g., injection molding). The first light-transmitting layer 521 surrounds the second light guide portion 54, and the connection between the first light guide portion 52 and the second light guide portion 54 is not covered by the first light-transmitting layer 521, thereby improving the light guiding efficiency between the first light guide portion 52 and the second light guide portion 54.

[0039] Please also refer to Figure 3 and Figure 4 The second lampshade 16 is connected to the side of the main housing 12 opposite to the first lampshade 14. The second lampshade 16 is generally plate-shaped and is embedded in the main housing 12. In this embodiment, the second lampshade 16 is made of a transparent material with high light transmittance, such as glass or plastic. In this embodiment, the diameter of the side of the main housing 12 connected to the second lampshade 16 is smaller than the diameter of the side connected to the first lampshade 14, so that the first lampshade 14, which is the main light-emitting side of the lamp 100, has a larger light-emitting area. The second lampshade 16 is provided with a relief groove 161, which extends along the length direction of the second lampshade 16 and penetrates the second lampshade 16 along the thickness direction. The side of the second light guide 54 opposite to the first light guide 52 protrudes to the outside through the relief groove 161. The side of the second light guide 54 protruding to the outside is covered with a second light-transmitting layer 541, the light transmittance of the second light-transmitting layer 541 being less than the light transmittance of the second light guide 54. In this embodiment, the second light guide 54 can also be made of a transparent material with high light transmittance. The second light guide 54 protrudes to the outside so that the lamp 100 achieves a bright and three-dimensional light-emitting effect when viewed from the side. The second light-transmitting layer 541, together with the first light-transmitting layer 521, makes the second lampshade 16 of the lamp 100 achieve a uniform light output effect from the front.

[0040] In other embodiments, the side of the second light guide 54 facing away from the first light guide 52 may be embedded in the relief groove 161 and not protrude to the outside, or may be completely housed in the mounting cavity 121, and the light transmitted by the second light guide 54 may be transmitted to the outside through the relief groove 161.

[0041] In this embodiment, the lamp 100 further includes a patterned film 70, which covers the side of the second lampshade 16 opposite to the first light guide portion 52. The patterned film 70 also has a recessed groove for the second light guide portion 54 to pass through. The patterned film 70 has a first light-emitting pattern area 72. A portion of the light emitted from the second light-emitting element 34 passes sequentially through the first light guide portion 52, the second lampshade 16, and the first light-emitting pattern area 72 (not shown in the figure). The outline of the first light-emitting pattern area 72 is set according to a preset pattern, and the area surrounded by its outline is for light transmission. The patterned film 70 makes the light emitted from the second lampshade 16 by the lamp 100 have a richer luminous effect. The patterned film 70 can be made of a material with high light transmittance. As an example, the patterned film 70 is a transparent polycarbonate film (PC film). An opaque area is formed by screen printing black ink on the patterned film 70, while the unscreened portion remains transparent to form the light-transmitting first light-emitting pattern area 72.

[0042] A light guide groove 523 is provided on the side of the first light guide portion 52 facing the second light-emitting element 34, and the light guide groove 523 is recessed relative to the surface of the first light guide portion 52. The arrangement of the light guide groove 523 is more conducive to the light emitted by the second light-emitting element 34 reaching the first light-emitting pattern area 72 (not shown in the figure) on the pattern film 70. The light guide groove 523 is located in the middle of the first light guide portion 52 and corresponds to the position of the second light guide portion 54. The light guide groove 523 is a trapezoidal groove, which has a better light-gathering effect.

[0043] In this embodiment, the light source module 100 may further include a third light-emitting element 38 and a second controller 39 (not shown in the figure). The third light-emitting element 38 is connected to the side of the circuit board 31 facing the second light-emitting element 34, and the second controller 39 is disposed on the circuit board 31 and electrically connected to the third light-emitting element 38 for controlling the operation of the third light-emitting element 38. The housing 10 may further include a third lampshade 18, which is opposite to the third light-emitting element 34 for conducting the light emitted by the third light-emitting element 34 to the outside of the housing 10. The second controller 39 can control the operation of the third light-emitting element 38, and the light emitted by the third light-emitting element 38 is conducted to the outside through the third lampshade 18, further enriching the light output effect of the lamp 100.

[0044] The third light-emitting element 38 can also be an LED bead. The number of third light-emitting elements 38 can be multiple or a single element. In this embodiment, there is one third light-emitting element 38, which can be located in the middle of the circuit board 31, between the two second light-emitting elements 36. The second controller 39 is also located on the circuit board 31 and electrically connected to the third light-emitting element 38 via the circuit board.

[0045] 39 can control the third light-emitting element 38 to work independently, making it independent of the first light-emitting element 32 and the second light-emitting element 36, so as to achieve the effect of single-lamp single-control and distinguish it from other lighting effects.

[0046] Please also refer to Figure 5 and Figure 6 The third lampshade 18 passes through the second lampshade 16 and is connected to the circuit board 31. The third lampshade 18 has an inner cavity 181 and covers the third light-emitting element 38 through the inner cavity 181. The lamp 100 may also include a second light guide 80, which is disposed in the inner cavity 181 and opposite to the third light-emitting element 38. The second light guide 80 is used to conduct the light emitted by the third light-emitting element 38 to the third lampshade 18. The third lampshade 18 has an inner cavity 181, and one open end of the third lampshade 18 is connected to the circuit board 31. Here, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or only surface contact. In this embodiment, one open end of the third lampshade 18 abuts against the circuit board 31.

[0047] The end of the third lampshade 18 furthest from the circuit board 31 is sequentially inserted through the first light guide 52, the second light guide 54, the second lampshade 16, and the area film 70. Correspondingly, the first light guide 52, the second light guide 54, the second lampshade 16, and the area film 70 are all provided with clearance grooves for the third lampshade 18 to pass through. The third lampshade 18 may include a body 182 and a limiting part 183. The limiting part 183 is connected to the end of the body 182 near the circuit board 31 and abuts against the circuit board 31. The outer diameter of the limiting part 183 is larger than the outer diameter of the body 182, and the limiting part 183 is located between the first light guide 52 and the circuit board 31. During installation, the third lampshade 18 is first inserted through the first light guide 50, and then the circuit board 31 is fixed to the first light guide 52 so that it and the first light guide 52 together clamp the limiting part 183, thereby achieving the effect of fixing the third lampshade 18.

[0048] The third light-emitting element 38 is located within the inner cavity 181. In this embodiment, the light source module 30 may further include a light-shielding element 90. The inner diameter of the limiting part 183 is also larger than the inner diameter of the body 182. The limiting part 183 may include a peripheral wall and a bottom wall, wherein the peripheral wall surrounds the third light-emitting element 38, and the bottom wall is spaced apart from the circuit board 31. The light-shielding element 90 is disposed between the limiting part 183 and the circuit board 31 and surrounds the third light-emitting element 38. The light-shielding element 90 may include at least one of the following structures: light-shielding foam, light-shielding rubber, light-shielding silicone, etc. In this embodiment, the light-shielding element 90 is light-shielding foam. The light-shielding foam can be elastically clamped between the bottom wall of the limiting part 83 and the circuit board 31. The arrangement of the light-shielding foam effectively blocks the leakage of light emitted by the third light-emitting element 38 and the second light-emitting element 36, achieving an independent lighting effect for the third light-emitting element 38.

[0049] In this embodiment, the body 182 has a second light-emitting pattern area 1821 opposite to the second light guide 80. The light transmittance of the second light-emitting pattern area 1821 is greater than that of the body 182. The light emitted by the third light-emitting element 18 passes through the second light guide 80 and the second light-emitting pattern area 1821 in sequence. The second light-emitting pattern area 1821 is disposed on the end face of the body 182 away from the circuit board 31. The outline of the second light-emitting pattern area 1821 is set according to a preset pattern, and the area surrounded by its outline is used for light transmission. The second light-emitting pattern area 1821 makes the light emitted by the lamp 100 from the third lampshade 18 have richer light effects. In order to ensure that the light effect of the third light-emitting element 38 is independent, in this embodiment, the body 182 is made of an opaque material, such as opaque plastic. The second light-emitting pattern area 182 can be disposed in a hollow part of the body 182 or can be a transparent structure connected to the body 182.

[0050] As an example, the second light-emitting pattern area 1821 is a through hole 1822 connecting the inner cavity 181 and the outside. One end of the second light guide 80 passes through the through hole 1822 and is exposed to the outside. The second light guide 80 can be snapped onto the body 182. One end of the second light guide 80 has a protrusion that matches the contour of the through hole 1822, and the protruding end of the second light guide 80 is embedded in the through hole 1822. The light emitted by the third light-emitting element 38 is transmitted to the outside through the second light guide 80. The second light-emitting pattern area 1821 can be adaptively adjusted according to the light effect seat required for actual application.

[0051] When the lamp 100 provided in this application is in use, the first controller 36 simultaneously controls the operation of the first light-emitting element 34 and the second light-emitting element 36. The light emitted by the first light-emitting element 34 is conducted from the first lampshade 14 to the outside of the housing 10, and the light emitted by the second light-emitting element 36 is conducted through the first light guide 50 to the second lampshade 16, and then conducted to the outside through the second lampshade 16. The lamp 100 provided in this application uses a single light source module 36 controlled by the same controller to achieve bi-sided light emission. The single light source module 36 avoids the structural redundancy and significant increase in the thickness of the lamp 100 caused by using two independent light sources, thus promoting the lightweighting of the lamp. In addition, the first lampshade 14 and the second lampshade 16 are integrated on both sides of the light source module 36, resulting in a compact structure and high luminous efficiency.
