Description

Technical Field

[0001] This application relates to the field of lighting fixtures, and more particularly to a lamp. Background Technology

[0002] With the continuous progress and development of the modern lighting industry, spatial lighting has become an indispensable part, and consumers and designers have diversified requirements for the light distribution of lighting fixtures. When existing lighting fixtures use optical lenses to emit light, the light usually comes out from one side of the optical lens, resulting in a small light-emitting area and a single light emission effect. Utility Model Content

[0003] In view of this, this application provides a lamp to solve the above-mentioned technical problems.

[0004] In this embodiment, the lamp includes a housing, a light-blocking member, and an optical lens. The housing has a receiving space and an opening communicating with the receiving space, and the light-blocking member is disposed in the opening. The light-blocking member has a light-transmitting hole communicating with the opening, and at least a portion of the structure of the light-blocking member is spaced apart from the housing to form a light-transmitting slit, which communicates with the opening and / or the receiving space. The optical lens is disposed inside the housing and includes a light-incident portion, a first light-exiting portion, and a second light-exiting portion, which are sequentially arranged along the extension direction of the optical axis of the lens. The first light-exiting portion has a first light-exiting surface that covers at least a portion of the light-transmitting hole, and the optical axis passes through the first light-exiting surface. A second light-exiting portion is connected to the first light-exiting portion and has a second light-exiting surface that is arranged along the extension direction of the optical axis and spaced apart from the optical axis. Light emitted through the second light-exiting portion passes through the second light-exiting surface and is exposed to the outside through the light-transmitting slit.

[0005] In some embodiments, a light-blocking member is disposed at the opening of the housing, a light-transmitting slit is formed between the opening of the housing and the light-blocking member, a second light-emitting part is disposed around the outer periphery of the first light-emitting part, and the second light-emitting surface and the light-transmitting slit are disposed opposite to each other.

[0006] In some embodiments, the luminaire further includes a light guide connected to a light-blocking member and disposed between the second light-emitting part and the light-transmitting gap.

[0007] In some embodiments, the light guide includes an annular portion and a protruding portion connected to each other. The annular portion surrounds the outer periphery of the second light-emitting portion, and the protruding portion is disposed on the side of the annular portion opposite to the second light-emitting surface, and is embedded in the light-transmitting gap and exposed to the outside.

[0008] In some embodiments, the light guide is detachably connected to the light blocker.

[0009] In some embodiments, the light guide and the light block are integrally formed.

[0010] In some embodiments, the light-blocking component is provided with a mounting groove, the opening of which faces the interior of the receiving space, and the light guide component is embedded in the mounting groove.

[0011] In some embodiments, the second light-emitting portion includes a main body and a protrusion. The main body surrounds the outer periphery of the first light-emitting portion and protrudes radially relative to the first light-emitting portion of the lens. The protrusion is located on the side of the main body opposite to the first light-emitting portion, so as to be embedded in the light-transmitting slit. The second light-emitting surface is located on the side of the protrusion opposite to the main body.

[0012] In some embodiments, the first light-emitting surface is the end face of an optical lens facing away from the light-incident portion. The radial dimension of the first light-emitting portion is smaller than the radial dimension of the second light-emitting portion to form a stepped portion. The stepped portion is disposed between the first light-emitting portion and the second light-emitting portion, and the light-blocking member abuts against the stepped portion.

[0013] In some embodiments, the second light-emitting surface is parallel to and spaced from the optical axis, the first light-emitting surface intersects the optical axis, and the first light-emitting surface is provided with multiple optical microstructures.

[0014] In some embodiments, the luminaire further includes a mounting bracket disposed within the receiving space and connected to the housing. An optical lens is detachably connected to the mounting bracket. The luminaire also includes a light-emitting module comprising a circuit board and light-emitting units interconnected with each other. The optical lens is disposed on the circuit board, the light-incident portion is a light-incident cavity, and the light-emitting units are disposed within the light-incident cavity.

[0015] In some embodiments, the optical lens has a connecting part on the side facing the mounting frame, the mounting frame has a mating part, the connecting part and the mating part are connected together, the connecting part is either a protrusion or a groove, and the mating part is either a protrusion or a groove.

[0016] Compared to existing technologies, this application provides a lamp fixture including a housing, a light-blocking component, and an optical lens. The light-blocking component is disposed at an opening in the housing. The light-blocking component has a light-transmitting hole communicating with the opening, and at least a portion of its structure is spaced apart from the housing to form a light-transmitting slit. The optical lens has a first light-emitting section and a second light-emitting section. Light can exit from the first light-emitting surface of the first light-emitting section to outside the light-transmitting hole and through the second light-emitting surface of the second light-emitting section to outside the light-transmitting slit, thereby expanding the light emission range of the lamp fixture. Furthermore, the light-incident section and the first light-emitting section of the optical lens are arranged sequentially along the extension direction of the optical axis of the optical lens, and the second light-emitting surface of the second light-emitting section is arranged opposite to the optical axis. Thus, the lamp fixture only needs to have one light-incident section to receive light from a single light source, achieving light emission in two different directions. On the one hand, this reduces the number of light sources and installation components, thereby reducing the overall size of the lamp fixture and reducing production costs; on the other hand, it improves the utilization rate of light and forms a coordinated light emission effect at the light-transmitting hole and the light-transmitting slit, improving the light emission effect and the user's visual experience.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] Please see Figure 1 This application provides a luminaire 100 for providing illumination or decorative light to a light-emitting area. The light-emitting area can be understood as some illuminated areas on a light-receiving surface, or as a spatial range. In this embodiment, the luminaire 100 can be a lighting lamp or an ambient lamp, and the light-receiving surface can include any one or more of the following, such as a ceiling, wall, or floor, etc., which are not specifically limited in this embodiment.

[0029] As an example, the luminaire 100 can be a wall washer light. The luminaire 100 is mounted on the wall by hinges or brackets, so that the luminaire 100 as a whole can rotate relative to the wall, that is, the orientation of the luminaire 100 can be freely adjusted, which can form a larger lighting range and adapt to adjustable multi-angle lighting, thereby improving the ease of use of the luminaire 100.

[0030] Please see Figure 1 and Figure 2In this embodiment, the lamp 100 may include a housing 10, a light-blocking member 20, and an optical lens 30. The housing 10 has a receiving space 11 and an opening 12 communicating with the receiving space 11. The light-blocking member 20 is disposed in the opening 12 and has a light-transmitting hole 201 communicating with the opening 12. At least a portion of the structure of the light-blocking member 20 is spaced apart from the housing 10 to form a light-transmitting slit 202, which communicates with the opening 12 or the receiving space 11. The optical lens 30 is disposed inside the housing 10 and includes a light-incident portion 31, a first light-exiting portion 32, and a second light-exiting portion 33. The light-incident portion 31 and the first light-exiting portion 32 are arranged sequentially along the extending direction of the optical axis O1 of the optical lens 30. The first light-exiting portion 32 has a first light-exiting surface 321, which covers at least a portion of the light-transmitting hole 201. The optical axis O1 passes through the first light-exiting surface 321. The second light-emitting part 33 is connected to the first light-emitting part 32. The second light-emitting part 33 has a second light-emitting surface 331 that is opposite to the optical axis O1. The second light-emitting surface 331 is arranged along the extension direction of the optical axis O1 and spaced apart from the optical axis O1. The light emitted by the second light-emitting part 33 passes through the second light-emitting surface 331 and is exposed to the outside through the light-transmitting slit 202.

[0031] It should be noted that the second light-emitting surface 331 does not necessarily have to be strictly aligned with the extension direction of the optical axis O1. For example, the second light-emitting surface 331 can be parallel to the optical axis O1, or it can be inclined relative to the optical axis O1 so that there is an angle between the extension plane of the second light-emitting surface 331 and the optical axis O1. Similarly, the first light-emitting surface 321 can be perpendicular to the optical axis O1 or intersect with the optical axis O1. This embodiment does not impose specific limitations on this.

[0032] By configuring the lamp 100 as described above, light can be emitted from the first light-emitting surface 321 of the first light-emitting part 32 to outside the light-transmitting hole 201 and from the second light-emitting surface 331 of the second light-emitting part 33 to outside the light-transmitting slit 202, thereby expanding the light-emitting range of the lamp 100. Furthermore, the light-incident part 31 and the first light-emitting part 32 of the optical lens 30 are arranged sequentially along the extension direction of the optical axis O1 of the optical lens 30, while the second light-emitting surface 331 of the second light-emitting part 33 is arranged away from the optical axis O1. Thus, the lamp 100 can achieve light emission in two different directions with only one light-incident part 31. This reduces the number of light sources and installation components, thereby reducing the overall size of the lamp 100 and lowering production costs. On the other hand, it improves light utilization and creates a coordinated light emission effect at the light-transmitting hole 201 and the light-transmitting slit 202, improving the light emission effect and the user's visual experience.

[0033] The specific components and structure of the lamp 100 will be introduced one by one in the following sections.

[0034] Please see Figure 1 and Figure 2In this embodiment, the lamp 100 includes a housing 10, which is generally cylindrical in shape and has an opening 12 and a receiving space 11. The opening 12 can be located at one end of the receiving space 11 and connect the receiving space 11 to the outside, so as to allow emitted light to be emitted from the housing 10. At the same time, the opening 12 is also used to install a light-blocking component 20 or other devices, which is not limited in this embodiment. The receiving space 11 is used to accommodate and protect the mounting components. The mounting components may include a light-blocking component 20, an optical lens 30, a mounting bracket 13, a light-emitting module 14, etc., which are not specifically limited in this embodiment.

[0035] Please see Figure 2 and Figure 3 For example, the mounting component may include a mounting bracket 13, which is disposed within the receiving space 11 and connected to the housing 10. The mounting bracket 13 is used to mount the optical lens 30 to fix the optical lens 30 within the housing 10, thereby providing a stable light output effect. This embodiment does not limit the connection method between the mounting bracket 13 and the housing 10, or the connection method between the mounting bracket 13 and the optical lens 30. For example, the mounting bracket 13 may be integrally formed with the housing 10, or it may be detachably connected to the housing 10. The optical lens 30 may be plugged into the mounting bracket 13, snapped into the mounting bracket 13, or fastened to the mounting bracket 13, depending on the actual usage requirements. As an example, the optical lens 30 has a connecting portion 35 on the side facing the mounting bracket 13, and the mounting bracket 13 has a mating portion 132. The connecting portion 35 may be a protruding structure, and the mating portion 132 may be a groove. The protruding portion has a groove and connects with the groove. The protruding structure may also be provided with a locking structure, such as a protrusion or a locking block, to improve the connection between the protruding portion and the groove.

[0036] The mounting components may further include a light-emitting module 14, which emits light and is disposed in the receiving space 11 and connected to an optical lens 30. The optical lens 30 is disposed in the light path formed by the light-emitting module 14. The light-emitting module 14 may include a light-emitting unit 141 and a circuit board 142. The circuit board 142 is electrically connected to the light-emitting unit 141 and provides power to the light-emitting unit 141. In this embodiment, the optical lens 30 is connected to the circuit board 142 and covers the light-emitting unit 141, so that the light emitted by the light-emitting unit 141 can be directly transmitted through the optical lens 30, thereby reducing light loss. The circuit board 142 is elongated, and the light-emitting unit 141 is detachably mounted on the circuit board 142. This embodiment does not limit the specific number or type of the light-emitting unit 141. For example, the number of light-emitting units 141 can be one or more, and the colors of the light emitted by multiple light-emitting units 141 can be the same or different.

[0037] The circuit board 142 can be a printed circuit board or a flexible circuit board. The light-emitting unit 141 can be an incoherent light source or a coherent light source. It should be noted that when the light-emitting unit 141 is a laser light source, a diffusion structure needs to be set between the optical lens 30 or the optical lens 30 and the light-emitting unit 141 to disperse the collimated light and form scattered light. As an example, the light-emitting unit 141 is an incoherent light source. For example, the light-emitting unit 141 can be an LED light source. On the one hand, it can improve the efficiency of converting electrical energy into light energy, thereby reducing energy waste. On the other hand, LED light sources generate less heat when illuminating, which plays a role in energy saving and environmental protection. Furthermore, LED light sources have a long service life and are safe, which can reduce damage to human eyes and reduce the frequency of light source replacement, thereby reducing the cost of use.

[0038] In this embodiment, an optical lens 30 is disposed within the housing 10 and is used to configure light. The optical lens 30 can be a total internal reflection (TIR) ​​lens, which can precisely control the propagation direction of light, allowing the light to be distributed according to a designed shape and angle. The optical lens 30 has an optical axis O1 and an entrance portion 31, a first exit portion 32, and a second exit portion 33 connected to each other. The entrance portion 31 and the first exit portion 32 are arranged sequentially along the extension direction of the optical axis O1. The optical axis O1 passes through the entrance portion 31 and the first exit portion 32, and the light-emitting surface of the second exit portion 33 is opposite to the optical axis O1 and spaced apart from the optical axis O1. In this embodiment, the entrance portion 31 is provided with an entrance cavity 3101, which is used to introduce and converge light. The light-emitting unit 141 can be specifically disposed within the entrance cavity so that most of the light can enter the optical lens 30 to improve the utilization rate of light. Both the first light-emitting part 32 and the second light-emitting part 33 are arranged in the light path of the light introduced through the light-inlet part 31. Thus, the lamp 100 only needs to be provided with one light-inlet part 31 and one corresponding light source to achieve light emission in two different directions. On the one hand, it can reduce the number of light sources to reduce the number of installation parts, thereby reducing the overall size of the lamp 100 and reducing the production cost; on the other hand, it can improve the light emission range and light emission brightness of the lamp 100.

[0039] Furthermore, the first light-emitting section 32 and the second light-emitting section 33 can form a coordinated light-emitting effect. Since both the first light-emitting section 32 and the second light-emitting section 33 are located on the propagation path of light, the light rays, after being converged by the light-incident section 31, will simultaneously propagate to the first light-emitting section 32 and the second light-emitting section 33 for emission. Part of the light rays are emitted through the first light-emitting section 32 along the direction of the optical axis O1 to form the first light-emitting area, and part of the light rays are emitted through the second light-emitting section 33 along a direction deviating from the optical axis O1 to form the second light-emitting area. The first light-emitting area and the second light-emitting area have different orientations, so the second light-emitting area and the first light-emitting area are superimposed to form the light-emitting area of ​​the lamp 100, which can improve the light-emitting effect of the lamp 100 and the user's visual experience.

[0040] This embodiment does not limit the specific shape of the first light-incident portion 31 and the second light-emitting portion 33. For example, the first light-emitting portion 32 can be arranged perpendicular to the optical axis O1 or intersect with the optical axis O1, and the first light-emitting portion 32 can be a curved part or a flat part; the second light-emitting portion 33 can be arranged parallel to the optical axis O1 or have an angle with the optical axis O1, and the second light-emitting portion 33 can be a flat part or a curved part. As an example only, in this embodiment, the first light-emitting portion 32 is arranged approximately perpendicular to the optical axis O1, and the second light-emitting portion 33 is arranged approximately parallel to the optical axis O1.

[0041] Specifically, the first light-emitting portion 32 is a planar portion disposed opposite to the light-incident portion 31, and is formed as the end of the optical lens 30. The first light-emitting portion 32 has a first light-emitting surface 321, which intersects with the optical axis O1, and is used to allow light emitted through the first light-emitting portion 32 to be emitted to the outside to form a first light-emitting area. In this embodiment, the distribution of the first light-emitting surface 321 in the first light-emitting portion 32 is not limited. For example, the first light-emitting surface 321 may be disposed on a portion of the first light-emitting portion 32 or may completely cover the surface of the first light-emitting portion 32, and can be configured according to actual usage requirements.

[0042] In some embodiments, to improve the light emission effect of the lamp 100, the first light-emitting surface 321 may also be provided with a plurality of optical microstructures 3211. The optical microstructures 3211 are used to improve the uniformity of the emitted light. This embodiment does not limit the specific type of the optical microstructures 3211 or their arrangement on the first light-emitting surface 321. For example, the optical microstructures 3211 may include at least any one of the following structures: bead structure, protrusion structure, groove, stripe structure, etc. The optical microstructures 3211 may be disposed on a portion of the first light-emitting surface 321 or may be distributed all over the first light-emitting surface 321 to form a specific light effect, and can be configured according to actual usage requirements.

[0043] The second light-emitting portion 33 is a curved surface connecting the light-incident portion 31 and the first light-emitting portion 32. It protrudes relative to the first light-emitting portion 32 and surrounds its outer periphery, thus the second light-emitting portion 33 and the first light-emitting portion 32 are arranged approximately perpendicularly. It should be noted that the curvature of the second light-emitting portion can be uniform throughout, forming a cylindrical surface with a planar cross-section. The curvature of the second light-emitting portion can also be non-uniform; this embodiment does not impose specific limitations on this and can be configured according to actual usage requirements. The second light-emitting portion 33 has a second light-emitting surface 331 facing away from the optical axis O1, parallel to and spaced from the optical axis O1. The second light-emitting surface 331 forms the outer peripheral wall of the second light-emitting portion 33, allowing light emitted through the second light-emitting portion 33 to exit to the outside and form a second light-emitting area.

[0044] Similarly, multiple light-uniforming microstructures (not shown in the figure) can also be provided on the second light-emitting surface 331 to improve the light emission uniformity of the second light-emitting surface 331. The light-uniforming microstructures can include at least one of the following structures: bead structure, protrusion structure, groove, stripe structure, etc. The light-uniforming microstructures can be disposed on a local part of the second light-emitting surface 331 or can be distributed all over the second light-emitting surface 331 to form a specific light effect. This embodiment does not impose specific limitations on this and can be set according to actual usage requirements.

[0045] It should be noted that in this embodiment, the second light-emitting area and the first light-emitting area have different orientations, and there is at least a partial non-overlapping area between them. That is, the light can be emitted from two different directions through the optical lens 30, thereby forming two different light emission effects. As a specific example, when the lamp 100 is installed on the wall, the first light-emitting part 32 can be set towards the ceiling, and the second light-emitting part 33 can extend along the wall, so that the lamp 100 can project light onto both the ceiling and the wall at the same time, which can improve the light emission range and the light emission brightness. It is understood that the orientation of the first light-emitting part 32 is not limited to the ceiling in this application; it can also be set perpendicular to the wall or towards the ground, etc., and can be set according to actual usage requirements.

[0046] Since the second light-emitting portion 33 is substantially perpendicular to the first light-emitting portion 32 and surrounds the outer periphery of the first light-emitting portion 32, the light emitted through the second light-emitting surface 331 can form a ring-shaped light effect. That is, the second illumination area surrounds the outer periphery of the first illumination area, further increasing the light emission range of the luminaire 100. It should be noted that the second light-emitting surface 331 can be a closed toroidal surface as mentioned above, or it can be an open surface segment. For example, the second light-emitting surface 331 can be multiple spaced-apart surface segments arranged circumferentially along the second light-emitting portion 33. Of course, the second light-emitting surface 331 can also be a single surface segment; this embodiment does not impose specific limitations on this.

[0047] Please see Figure 3 In some embodiments, the second light-emitting portion 33 serves as a connector for the optical lens 30 to be detachably connected to the mounting bracket 13. Specifically, the second light-emitting portion 33 extends to the mounting bracket 13 in a direction away from the first light-emitting portion 32. The mounting bracket 13 is provided with a corresponding snap-fit ​​groove 131 for the second light-emitting portion 33. One end of the second light-emitting portion 33 connected to the mounting bracket 13 is provided with a snap-fit ​​portion 332 corresponding to the snap-fit ​​groove. The snap-fit ​​portion 332 snaps into the snap-fit ​​groove 131 to achieve a fixed connection between the optical lens 30 and the mounting bracket 13. By extending the second light-emitting portion 33, the light output brightness and light output efficiency of the second light-emitting portion 33 can be improved. On the other hand, it eliminates the need for additional connectors for connecting to the mounting bracket 13, thereby reducing the number of mounting parts, reducing the overall size of the lamp 100, and lowering production costs.

[0048] In this embodiment, since the light emitted by the light-emitting module 14 can be emitted from the first light-emitting surface 321 and the second light-emitting surface 331 of the optical lens 30, in order to have a clear dividing line between the light emitted through the first light-emitting surface 321 and the light emitted through the second light-emitting surface 331 to improve the sense of layering of the light emission effect, the light-blocking member 20 can be disposed between the first light-emitting part 32 and the second light-emitting part 33, and located in the light emission direction of the first light-emitting part 32 and the second light-emitting part 33. That is, by providing the light-blocking member 20, a clear dividing line can be made between the first light-emitting area and the second light-emitting area. In addition, the light-blocking member 20 can also be used as a mounting component to improve the overall appearance of the lamp 100.

[0049] Please see Figures 2 to 4 Specifically, the light-blocking member 20 is disposed at the end of the housing 10, that is, the light-blocking member 20 is located at the opening 12, and is at least partially connected to the optical lens 30 to prevent the light-blocking member 20 from moving during the movement of the lamp 100, thereby ensuring the stability of the light output effect. This embodiment does not limit the way the light-blocking member 20 is connected to the optical lens 30. For example, the light-blocking member 20 can be attached to the optical lens 30 by adhesive or by a connector. In this embodiment, a stepped portion 34 for mounting the light-blocking member 20 is formed on the optical lens 30. Specifically, the second light-emitting portion 33 protrudes relative to the first light-emitting portion 32 and surrounds the outer periphery of the first light-emitting portion 32, that is, the radial dimension of the first light-emitting portion 32 is smaller than the radial dimension of the second light-emitting portion 33 to form the stepped portion 34. The stepped portion 34 is disposed between the first light-emitting portion 32 and the second light-emitting portion 33, and the light-blocking member 20 is stacked and pressed onto the stepped portion 34 to achieve a fixed connection with the optical lens 30.

[0050] Please see Figures 3 to 5In this embodiment, the outer contour of the light-blocking member 20 is generally annular to match the opening 12 and the optical lens 30. The light-blocking member 20 may include a light-blocking portion 21 and a light-transmitting portion 22, with the light-blocking portion 21 surrounding the outer periphery of the light-transmitting portion 22. Specifically, the light-transmitting portion 22 is opposite to the first light-emitting surface 321 and is located in the light path of the first light-emitting portion 32 so that light can be emitted from the first light-emitting surface 321. In this embodiment, the light-transmitting portion 22 may be a light-transmitting hole 201 communicating with the opening 12. Figure 1 The first light-emitting surface 321 covers at least a portion of the light-transmitting hole 201 so that the first light-emitting surface 321 can be exposed to the outside through the light-transmitting hole 201, forming a first light-emitting area. In other embodiments, the light-transmitting part 22 may also be a light-transmitting solid, such as light-transmitting glass, light-transmitting plastic, etc., and this embodiment does not impose specific limitations on it.

[0051] In this embodiment, the light-blocking part 21 is arranged in a ring shape. The light-blocking part 21 is connected to the optical lens 30 and located at the junction of the first light-emitting part 32 and the second light-emitting part 33, separating the first light-emitting region and the second light-emitting region. This embodiment does not limit the specific form of the light-blocking part 21. For example, as an example, the light-blocking part 21 can be a ring-shaped light-blocking paper or a cured light-blocking ink layer, with the light-blocking paper and light-blocking ink layer attached to the surface of the optical lens 30 and separating the first light-emitting part 32 and the second light-emitting part 33. In this embodiment, the light-blocking part can be a light-blocking ring, making the light-blocking part 20 a ring-shaped light-blocking cover with a light-transmitting hole 201, which is detachably connected to the optical lens 30 for easy maintenance and management of the lamp 100.

[0052] In this embodiment, to facilitate light emission from the second light-emitting section 33, at least a portion of the structure of the light-blocking member 20 (i.e., at least a portion of the structure of the light-blocking member 21) extends along the axial direction of the housing 10 and forms a light-transmitting slit 202 spaced apart from the end of the housing 10. This allows light emitted through the second light-emitting section 33 to pass through the second light-emitting surface 331 and be exposed to the outside through the light-transmitting slit 202, forming a second light-emitting area. Specifically, the light-transmitting slit 202 is formed between the opening 12 of the housing 10 and the light-blocking member 20. The light-transmitting slit 202 communicates with the opening 12 and / or the receiving space 11 and is disposed opposite to the second light-emitting section 33. "Opposite" can be understood as the plane containing the light-transmitting slit 202 intersecting with the second light-emitting section 33. In this embodiment, by providing a light-transmitting hole 201 and at least a portion of the structure of the light-blocking member 20 and the light-transmitting slit 202 formed by the spaced intervals between them and the housing 10, it is possible to ensure that light can be emitted from the optical lens 30 to the outside to form a light effect of coordinated light emission from the first light-emitting area and the second light-emitting area, thereby improving the light emission effect and the user's visual experience. In addition, it also enables the first light-emitting area and the second light-emitting area to have a clear dividing line, which can improve the sense of layering of the light emission effect.

[0053] It should be noted that in this embodiment, the light-transmitting slit 202 is arranged around the light source to ensure that the light emitted through the second light-emitting part 33 forms a ring-shaped light effect similar to a strip-shaped light ring on the outer surface of the lamp 100. The second light-emitting part 33 can be spaced apart from the light-transmitting slit 202, or it can protrude into the light-transmitting slit 202 and be directly exposed to the outside. This embodiment does not impose specific limitations on this.

[0054] Please see Figures 3 to 5 As an example, the second light-emitting section 33 and the light-transmitting slit 202 are spaced apart, and the second light-emitting surface 331 faces the light-transmitting slit 202 and is disposed opposite to the light-transmitting slit 202, so that the light emitted through the second light-emitting section 33 passes through the second light-emitting surface 331 and is exposed to the outside through the light-transmitting slit 202. Since the second light-emitting section 33 and the light-transmitting slit 202 are spaced apart, in order to ensure light emission efficiency and light emission effect, the lamp 100 may also include a light guide 40. The light guide 40 is disposed between the light-blocking member 20 and the light-transmitting slit 202, and the light guide 40 is transparent so as to conduct light to the outside of the light-transmitting slit 202.

[0055] Specifically, the light guide 40 is connected to the light blocker 20 and disposed between the second light emitting portion 33 and the light-transmitting gap 202. The light guide 40 may include an annular portion 41 and a protruding portion 42. The annular portion 41 surrounds the outer periphery of the second light emitting portion 33 and faces the light-transmitting gap 202. It is understood that the annular portion 41 may be disposed close to the second light emitting portion 33 or spaced apart from it. When the annular portion 41 and the second light emitting portion 33 are spaced apart, the distance between them should be as small as possible so that the light emitted through the second light emitting portion 33 can be transmitted to the light guide 40 through a shorter path, thereby reducing light loss. In this embodiment, at least a portion of the structure of the annular portion 41 is also used to connect the light blocker 20 to fix the light guide 40 and the light blocker 20. Specifically, the light blocker 20 is provided with a mounting groove 23, which may be a groove structure formed by a recess in the inner peripheral wall of the light blocker 21. The mounting groove 23 is used to install the light guide 40. The opening of the mounting groove 23 faces the interior of the receiving space 11. The annular part 41 is embedded in the mounting groove 23 to achieve a fixed connection between the light guide 40 and the light blocker 20.

[0056] In this embodiment, the protruding portion 42 is connected to the annular portion 41 and protrudes into the light-transmitting slit 202. Specifically, the protruding portion 42 is disposed on the side of the annular portion 41 opposite to the second light-emitting surface 331, embedded in the light-transmitting slit 202, and exposed to the outside. Thus, the light emitted through the second light-emitting portion 33 passes through the second light-emitting surface 331, enters the annular portion 41, is conducted to the protruding portion 42, and finally exits to the outside to form the second light-emitting area. In addition, the protruding portion 42 embedded in the light-transmitting slit 202 can also improve the connection stability of the light guide 40, prevent the light guide 40 from moving, and form a stable and reliable light emission effect.

[0057] It should be noted that the light guide 40 can be detachably connected to the light blocker 20, or it can be integrally formed with the light blocker 20. This embodiment does not impose specific limitations on this. For example, the light guide 40 and the light blocker 20 can be integrally formed using a two-color injection molding process to ensure the connection stability of the light blocker 20 and the light guide 40 and to improve the aesthetics of the lamp 100.

[0058] Please see Figure 6 and Figure 7 As another example, the second light-emitting part 33 can also protrude into the light-transmitting slit 202 to be directly exposed to the outside. That is, the first light-emitting surface 321 is formed on the surface of the second light-emitting part 33 that is exposed outside the light-transmitting slit 202, so that the light emitted through the second light-emitting part 33 is always transmitted inside the optical lens 30, forming a stable light-emitting effect.

[0059] Specifically, the second light-emitting portion 33 may include a main body portion 333 and a protrusion portion 334. The main body portion 333 is used to conduct light and surrounds the outer periphery of the first light-emitting portion 32 to form a ring-shaped light effect. The main body portion 333 is also used to connect between the light-blocking member 20 and the mounting bracket 13 to fix the optical lens 30 within the housing 10. As a specific example, the main body portion 333 protrudes radially relative to the first light-emitting portion 32 along the optical lens 30 to form the aforementioned stepped portion 34 for mounting the light-blocking member 20. At least a portion of the structure of the end of the main body portion 333 facing away from the stepped portion 34 protrudes to the mounting bracket 13 to form the aforementioned connecting member.

[0060] The protrusion 334 is used to transmit light transmitted through the main body 333 to the outside. It is located on the side of the main body 333 away from the first light-emitting part 32 and is embedded in the light-transmitting slit 202. That is, the second light-emitting surface 331 is located on the side of the protrusion 334 away from the main body 333 so as to directly contact the outside. Since the second light-emitting surface 331 is displayed to the outside through the protrusion 334, the second light-emitting surface 331 also serves a decorative function to improve the aesthetics of the lamp 100. For example, the second light-emitting surface 331 can be configured as a textured surface or a patterned surface, etc., and this embodiment does not impose specific limitations on this. By setting the above-mentioned second light-emitting part 33, it is possible to ensure that the light transmitted to the second light-emitting part 33 has good light-emitting efficiency and light-emitting effect without the need for the light guide 40, and the assembly steps and complexity of the lamp 100 are reduced, thereby improving production efficiency.

[0061] In summary, the luminaire 100 includes a housing 10, a light-blocking member 20, and an optical lens 30. The light-blocking member 20 is disposed at the opening of the housing 10. The light-blocking member has a light-transmitting hole 201 communicating with the opening, and at least a portion of its structure is spaced apart from the housing 10 to form a light-transmitting slit 202. The optical lens 30 has a first light-emitting portion 32 and a second light-emitting portion 33. Light can be emitted from the first light-emitting surface 321 of the first light-emitting portion 32 to outside the light-transmitting hole 201 and from the second light-emitting surface 331 of the second light-emitting portion 33 to outside the light-transmitting slit 202, thereby expanding the light emission range of the luminaire 100. Furthermore, the light-incident portion 31 and the first light-emitting portion 32 of the optical lens 30 are arranged sequentially along the extension direction of the optical axis O1 of the optical lens 30, and the second light-emitting surface 331 of the second light-emitting portion 33 is arranged away from the optical axis O1. Thus, the lamp 100 can achieve light emission in two different directions with only one light-incident portion 31. On the one hand, it can reduce the number of light sources and installation parts, thereby reducing the overall size of the lamp 100 and reducing production costs. On the other hand, it can improve the utilization rate of light and form a linkage light emission effect at the light-transmitting hole 201 and the light-transmitting slit 202, thereby improving the light emission effect and the user's visual experience.
