[0028] See also Figure 1 and Figure 2 The embodiment of the present application provides a lamp 100. In this embodiment, the lamp 100 is used to provide lighting. The lamp 100 can be a wall washer or an atmosphere lamp. Specifically, it can be used for ceiling lighting, wall lighting, stage decoration lighting, etc.

[0029] See also Figure 2In one embodiment provided in the present application, a lamp 100 includes a first light-transmitting cover 10, a second light-transmitting cover 40, and a light source module 20. The first light-transmitting cover 10 is provided with a first accommodating cavity 11 and a first opening 12, and the first opening 12 is located at one end of the first light-transmitting cover 10 and communicates with the first accommodating cavity 11. The second light-transmitting cover 40 is arranged on a side of the first light-transmitting cover 10 away from the first accommodating cavity 11, and the second light-transmitting cover 40 is provided with a second accommodating cavity 41. The light source module 20 is arranged in the first accommodating cavity 11, and part of the emitted light generated by the light source module 20 directly transmits the first light-transmitting cover 10 and the second light-transmitting cover 40. Among them, the light generated by the light source module 20 can be directly emitted through the first light-transmitting cover 10 to illuminate the corresponding area or serve as decoration. Part of the light generated by the light source module 20 can be transmitted to the second light-transmitting cover 40 for emission. On the one hand, the number of light source modules 20 to be set can be reduced, and the number of installed parts can be reduced, thereby reducing the space volume of the lamp 100 and reducing the production cost; on the other hand, one light source module 20 can provide lighting for two areas or form decorative light for two areas, which can improve the lighting range and lighting effect of the lamp 100. Furthermore, part of the light generated by the light source module 20 that cannot be emitted through the first light-transmitting cover 10 can be emitted through the second light-transmitting cover 40 and emitted to the area corresponding to the second light-transmitting cover 40, which can improve the light utilization rate and form a linked light emission effect, thereby improving the user's visual experience.

[0030] Next, each component of the lamp 100 and the specific structure of each component will be introduced one by one.

[0031] See also Figures 2 to 4 In this embodiment, the light source module 20 is arranged in the first accommodating cavity 11 formed by the first light-transmitting cover 10, and the light source module 20 is used to generate light and emit light to the illumination area. In this embodiment, the light source module 20 includes a plurality of light-emitting units 21 and a support column 22, and the light-emitting unit 21 is detachably mounted on the support column 22, so as to facilitate the maintenance and replacement of the light source module 20. Specifically, the support column 22 serves as a mounting carrier of the light-emitting unit 21, which is arranged in the first accommodating cavity 11 and is spaced apart from the inner surface of the first light-transmitting cover 10. A plurality of first supporting connectors 221 are arranged inside the support column 22, and the first supporting connector 221 can be a docking pin or a docking groove, and the docking pin or the docking groove is detachably fastened to the connectors of other components. By adopting the plug-in connection method, the stability of the connection of the light-emitting module of the lamp 100 during use can be ensured, and at the same time, the connection method is simple and fast, which is convenient for disassembly and assembly and maintenance management, and improves assembly efficiency.

[0032] In this embodiment, a plurality of light-emitting units 21 are arranged at intervals on the outer wall surface of the support column 22. Therefore, the light source module 20 can emit light at all angles, and the light generated by the light source module 20 can cover the area where the first light-transmitting cover 10 is located, and can maximize the light output and improve the lighting brightness. In this embodiment, the light-emitting unit 21 is an incoherent light source, and the light-emitting unit 21 can be a high-pressure gas light source such as a halogen light bulb, UHP (ultra-high pressure mercury bulb), UHE (ultra-high pressure mercury bulb) or an LED light source, etc. In this embodiment, the light-emitting unit 21 is an LED light source, which can be a single-color LED lamp bead or a three-color LED lamp bead. On the one hand, it can improve the efficiency of converting electrical energy into light energy, thereby reducing energy waste, and at the same time, the heat generated by the LED light source during illumination is less, which plays a role in energy saving and environmental protection; on the other hand, the LED light source has a long service life, which reduces the frequency of light source replacement and thus reduces the cost of use. At the same time, LED can avoid damage to human eyes and improve safety of use. As an example, a plurality of light-emitting units 21 are arranged at intervals on a flexible circuit board 23, and the flexible circuit board 23 is mounted on the outer wall surface of the support column 22. The flexible circuit board 23 has the characteristics of high wiring density, light weight, thin thickness and good bending performance. It can be used as a wire to connect all the light-emitting units 21 into a string. At the same time, it can be bent up and down or left and right at will, which is convenient for installation.

[0033] In this embodiment, the first light-transmitting cover 10 forms a first light-emitting area 101. The first light-emitting area 101 extends from the outer wall of the first light-transmitting cover 10, and most of the emitted light generated by the light source module 20 is emitted through the first light-transmitting cover 10, forming a corresponding light effect on the first light-emitting area 101. The first light-transmitting cover 10 is provided with a first accommodating cavity 11 and a first opening 12, the first opening 12 is located at one end of the first light-transmitting cover 10 and communicates with the first accommodating cavity 11, and the interior of the first accommodating cavity 11 is used to install the light source module 20 and other parts. The material of the first light-transmitting cover 10 may include ABS plastic, PC plastic or other hard plastic, which can not only reduce the weight of the first light-transmitting cover 10 to achieve lightweight, but also enable the light-transmitting cover to have a certain stability, thereby effectively protecting the parts inside the first accommodating cavity 11. On the other hand, the plastic material has the characteristics of low cost, good plasticity, easy processing, and not easy to break, which can reduce the production cost of the first light-transmitting cover 10 and thus reduce the production cost of the lamp 100. It should be noted that the material of the first light-transmitting cover 10 can also be a light-transmitting material such as light-transmitting glass, acrylic plate, etc., and the outer contour of the first light-transmitting cover 10 can be cylindrical, cubic, spherical or umbrella-shaped, etc., and this embodiment does not limit this. As an example, the first light-transmitting cover 10 is a cylindrical light-transmitting cover. The light generated by the light source module 20 forms a cylindrical rod light effect on the outer wall of the first light-transmitting cover 10, visually forming a large light-emitting body, which can improve the brightness and lighting effect of the lighting. At the same time, a rounded structure 14 is provided on the side of the first light-transmitting cover 10 away from the first opening 12. The light generated by the light source module 20 can be reflected to different parts of the first light-emitting area 101 through the rounded structure 14, which can avoid the light from gathering at the corner and reduce the light from being emitted to the non-lighting area or non-decorative area, which can improve the light utilization rate and further increase the lighting range or decorative area.

[0034] In the present embodiment, the second light-transmitting cover 40 forms a second light-emitting area 401. Specifically, the second light-transmitting cover 40 is a cylindrical light-transmitting cover, and the light generated by the light source module 20 forms a cylindrical rod light effect on the outer wall of the second light-transmitting cover 40, and forms a linkage light-emitting lighting effect and a decorative effect with the first light-transmitting cover 10. In the length direction (for example, the axis direction of the above-mentioned cylindrical shape), the length of the second light-transmitting cover 40 is much smaller than the length of the first head light 10, so that the light effects formed by the first light-emitting area 101 and the second light-emitting area 401 are obviously different, and the light effects are more flexible and rich. The second light-transmitting cover 40 and the first light-transmitting cover 10 are basically stacked, for example, they can be stacked with an intermediate connecting member (such as a light guide 30) in between. In the present embodiment, the second light-transmitting cover 40 is arranged on the side of the first light-transmitting cover 10 away from the first accommodating cavity 11. The second light emitting area 401 extends from the outer wall of the second light-transmitting cover 40, and the second light emitting area 401 and the second light emitting area 401 are connected along the projection of the specified direction O1, forming a lighting effect without dark areas and linked light emission. The "specified direction O1" mentioned above can be understood as the direction of the length of the light source module 20. Part of the emitted light generated by the light source module 20 is transmitted to the inner wall of the first light-transmitting cover 10 for reflection and then emitted to the second light emitting area 401 through the second light-transmitting cover 40; or part of the emitted light generated by the light source module 20 that deviates from the first light-transmitting cover 10 can be directly transmitted to the second light-transmitting cover 40, which can improve the lighting brightness and the utilization rate of light on the one hand; on the other hand, a single light source module 20 can be used to achieve the light effect of emitting light in two areas, enrich the lighting effect and improve the user's visual experience. At the same time, it can reduce the number of light source modules 20, reduce the number of installed parts, and reduce the space volume of the lamp 100, thereby reducing the production cost.

[0035] Specifically, when the lamp 100 is installed and used, it is only necessary to set the light source module 20 in the first light-transmitting cover 10 to provide lighting for the first light-emitting area 101 and the second light-emitting area 401 at the same time or form decorative light for the two areas, which can improve the lighting range of the lamp 100. The first light-transmitting cover 10 is also provided with a second accommodating cavity 41. The interior of the second accommodating cavity 41 is used to install parts, and the parts can specifically be a support, a heat sink, a reflector 50, etc. The material of the second light-transmitting cover 40 can include ABS plastic, PC plastic or other hard plastics, which can not only reduce the weight of the second light-transmitting cover 40 to achieve lightweight, but also enable the light-transmitting cover to have a certain stability, thereby effectively protecting the parts inside the first accommodating cavity 11. On the other hand, the plastic material has the characteristics of low cost, good plasticity, easy processing, and not easy to break, which can reduce the production cost of the first light-transmitting cover 10 and thus reduce the production cost of the lamp 100. It should be noted that the material of the second light-transmitting cover 40 can also be a light-transmitting material such as light-transmitting glass and acrylic board, which is not limited in this embodiment.

[0036] As an example, the material color selected for the second light-transmitting cover 40 and the material color selected for the first light-transmitting cover 10 may be different, for example, the color of the second light-transmitting cover 40 is blue, and the color of the first light-transmitting cover 10 is red. When the light generated by the light source module 20 is emitted through the first light-transmitting cover 10 and the second light-transmitting cover 40 at the same time, two different colors of light effects can be achieved, which can form a variety of light effect lighting and improve the user's visual experience. It should be noted that the number of second light-transmitting covers 40 can be multiple. When installed and used, multiple second light-transmitting covers 40 are stacked and form a second light-transmitting area 401. Different numbers of second light-transmitting covers 40 can be superimposed according to the size of the area of ​​the lighting area or the decorative area. The material colors of different numbers of second light-transmitting covers 40 may also be different, thereby forming a colorful light-emitting light effect and improving the user's visual experience.

[0037] As another example, the material of the second light-transmitting cover 40 is different from that of the first light-transmitting cover 10. Specifically, the first light-transmitting cover 10 may be hard plastic, the second light-transmitting cover 40 may be transparent glass, or the outer surface pattern of the first light-transmitting cover 10 may be inconsistent with the outer surface pattern of the second light-transmitting cover 40, etc., which can form different light-emitting effects and form different pattern light effects in the lighting area or the decorative area, which can improve the user's visual experience. Similarly, the number of the second light-transmitting cover 40 can be multiple. When installed and used, multiple second light-transmitting covers 40 are stacked and formed to form a second light-transmitting area 401, and different numbers of second light-transmitting covers 40 can be stacked according to the size of the area of ​​the lighting area or the decorative area. The materials and patterns of different numbers of second light-transmitting covers 40 may also be different, thereby forming a variety of light effect patterns to improve the user's visual experience. The above examples can all achieve multiple light effects and provide lighting or decorative light effects for two areas when only one light source module 20 is set, which can reduce the installation of parts, thereby reducing the space volume of the lamp 100 and reducing production costs.

[0038] In order to further improve the transmission efficiency of light to the second light-transmitting cover 40 and improve the uniformity of light, the lamp 100 can be additionally provided with a light guide 30 for guiding light. The light guide 30 is generally plate-shaped and is suitable for matching the size of the second light-transmitting cover 40, and can receive the outgoing light from different directions generated by the light source module 20. The outgoing light is transmitted to the second light-transmitting cover 40 through the light guide 30 and is emitted to the second light-emitting area 401. It can be understood that the lamp 100 may not be provided with a light guide 30. The purpose of adding a light guide 30 is to improve the transmission efficiency of the outgoing light and the uniformity of light guiding. The light guide 30 can be installed or not installed according to actual needs. The number of light guides 30 installed and the connection method between adjacent light guides 30 are not limited in this embodiment.

[0039] See also Figures 3 to 5In this embodiment, the light guide 30 is disposed between the first light-transmitting cover 10 and the second light-transmitting cover 40. Specifically, the light guide 30 is located at the first opening 12 and separates the outer surfaces of the first light-transmitting cover 10 and the second light-transmitting cover 40 to form a first light-emitting area 101 and a second light-emitting area 401, and the first light-emitting area 101 and the second light-emitting area 401 are arranged at intervals. The light guide 30 transmits the light generated by the light source module 20 located in the first light-transmitting cover 10 to the second light-transmitting cover 40. Specifically, part of the emitted light generated by the light source module 20 deviates from the first light-emitting area 101, and the part of the emitted light can be transmitted to the second light-transmitting cover 40 through the light guide 30 and emitted to the second light-emitting area 401, thereby improving the light utilization rate. In addition, one light source module 20 provides lighting for two areas at the same time, which can reduce the number of light source modules 20 while increasing the lighting range, thereby achieving the purpose of reducing the number of installed parts, reducing the spatial volume of the lamp 100, and thus reducing the production cost. The light guide 30 also has an outer peripheral wall, and the outer peripheral wall, the outer surface of the first light-transmitting cover 10, and the outer surface of the second light-transmitting cover 40 are smoothly connected along a specified direction. When the outgoing light generated by the light source module 20 is transmitted to the connection between the first light-transmitting cover 10, the second light-transmitting cover 40, and the light guide 30, there will be no light leakage, and the outgoing light generated by the light source module 20 can be concentrated in the lamp 100, thereby improving the utilization rate of light and the brightness of lighting.

[0040] In other embodiments, the light guide 30 is made of a light-transmitting material, so the outer peripheral wall of the light guide 30 can also be used for light transmission, so that the light generated by the light source module 20 is emitted through the outer peripheral wall to form a third light-transmitting area 301, and the third light-transmitting area 301 extends outward from the outer peripheral wall. The first light-transmitting area 101, the second light-transmitting area 401 and the third light-transmitting area 301 are linked to emit light, and are connected at the outer peripheral wall, the outer surface of the first light-transmitting cover 10 and the outer surface of the second light-transmitting cover 40, so that the outer contour of the lamp 100 is a light-emitting surface in the length direction, thereby increasing the utilization area of ​​the lamp 100. At the same time, there is no dark area at the outer contour of the lamp 100, and the light is evenly emitted at each connection, and a smooth and continuous light effect is formed, thereby improving the visual experience of the user. As an example, at least one of the materials of the outer peripheral wall, the outer surface of the first light-transmitting cover 10, and the outer surface of the second light-transmitting cover 40 is different from the materials of the other two. Specifically, it can be light-transmitting glass, transparent plastic, acrylic plate, etc., which is not limited in this embodiment. Alternatively, the same material with different light transmittances can be selected. Light passing through materials with different light transmittances can form different light effects in the lighting area, thereby increasing the three-dimensionality of the lighting area or the atmosphere area. As another example, at least one of the colors of the outer wall, the outer surface of the first light-transmitting cover 10, and the outer surface of the second light-transmitting cover 40 is different from the colors of the other two. The light source module 20 emits light through areas of different colors to form a colorful illumination effect, which can form a variety of light effects and enhance the user's visual experience. Please refer to Figure 6 The light guide 30 has a first surface 32 and a second surface 33, and the first surface 32 faces the first accommodating cavity 11. The second surface 33 faces the second accommodating cavity 41. The light guide 30 also has a first docking portion 31, and the first docking portion 31 is used to be fastened to the first light-transmitting cover 10 and the second light-transmitting cover 40. Specifically, the first docking portion 31 is arranged at the junction of the first light-transmitting cover 10, the second light-transmitting cover 40 and the light guide 30. The first docking portion 31 has a first docking end 311 and a second docking end 312, and the first docking end 311 and the second docking end 312 are opposite to each other, and the first docking end 311 is arranged on the first surface 32, and the second docking end 312 is arranged on the second surface 33. The first docking end 311 and the second docking end 312 can be docking grooves or docking protrusions. The first light-transmitting cover 10 has a second docking portion 13, and the second light-transmitting cover 40 has a third docking portion 42, and the second docking portion 13 and the third docking portion 42 can be docking grooves or docking protrusions. As an example, the first docking portion 31 is a docking groove, that is, the two docking ends 311 are docking grooves. The second docking portion 13 and the third docking portion 42 are both docking protrusions, and the opening directions of the docking grooves are respectively toward the second docking portion 13 and the third docking portion 42, and the docking protrusions protrude into the corresponding docking grooves. Through the plug-in connection, on the one hand, a fastening connection between the first light-transmitting cover 10, the second light-transmitting cover 40 and the light guide 30 can be achieved, thereby ensuring the stability of the lamp 100 during use. On the other hand, the detachable docking connection is simple and convenient, easy to install and disassemble, and can improve the production efficiency during the production process.

[0041] In some embodiments, the light guide 30 also has a plurality of first surface microstructures 34. The first surface microstructure 34 is at least arranged on one of the first surface 32 or the surface. The first surface microstructure 34 may be a honeycomb structure, a scale-like structure, a beaded structure, etc. As an example, the first surface microstructure 34 of the light guide 30 is a beaded structure, which is roughly a regular hexagon. A plurality of first surface microstructures 34 are arranged on the first surface 32. When the outgoing light generated by the light source module 20 passes through the first surface 32, it is fully mixed under the action of the first surface microstructure 34 to achieve a uniform light output effect, and avoid the phenomenon of color difference or stratification of the outgoing light spot, thereby achieving a good light output effect. At the same time, the beaded structure can change the reflection path, and transmit the outgoing light emitted through the light guide 30 to different positions of the second light output area 401, which can increase the illumination range and improve the illumination effect. It should be noted that the first surface microstructure 34 can also be arranged on the second surface 33, or the first surface microstructure 34 can be arranged on both the first surface 32 and the second surface 33. The first surface microstructure 34 may be distributed over at least one of the first surface 32 or the second surface 33 , or may be distributed at different positions on at least one of the first surface 32 or the second surface 33 .

[0042] See also Figure 3 and Figure 7In this embodiment, the lamp 100 further includes a reflector 50. The reflector 50 is used to reflect part of the outgoing light generated by the light source module 20 and entering the second light-transmitting cover 40 to the second light-emitting area 401. The reflector 50 is disposed in the second accommodating cavity 41, and the light source module 20 and the reflector 50 are stacked. The reflector 50 has a first connecting surface 51 and a second connecting surface 52. The first connecting surface 51 and the second connecting surface 52 are arranged at intervals and are respectively located at both ends of the reflector 50. The first connecting surface 51 and the second connecting surface 52 are connected by a reflecting surface 53. The first connecting surface 51, the second connecting surface 52 and the reflecting surface 53 form the outer contour of the reflector 50. Specifically, the inner diameter of the first connecting surface 51 is smaller than the inner diameter of the second connecting surface 52, so that the reflector 50 forms a frustum structure and plays a certain supporting role. During installation and use, the first connection surface 51 is arranged in contact with the light guide 30 and a plurality of second supporting connectors 512 are arranged on the side of the first connection surface 51 facing away from the light guide 30. The plurality of second supporting connectors 512 are used to be plugged and connected detachably with a plurality of connectors (not shown in the figure) in the light source module 20. As an example, the connector (not shown in the figure) is a connecting boss, and the second supporting connector 512 is a connecting groove. The connecting boss and the connecting groove are plugged and connected to realize the fastening connection between the light source module 20 and the reflector 50. It can be understood that at least one connector (not shown in the figure) and one second supporting connector 512 can be provided to be matched and connected, or a plurality of connectors and a plurality of second supporting connectors 512 can be provided to be matched and connected. The purpose of providing the matching connection between the connector (not shown in the figure) and the second supporting connector 512 is to ensure a firm connection between the light source module 20 and the reflector 50. Different numbers of first supporting connectors 221 and second supporting connectors 512 can be provided according to the installation requirements. The number of the first supporting connectors 221 and the second supporting connectors 512 is not limited in this embodiment.

[0043] In the present embodiment, the reflector 50 further has a first connection end 511 and a second connection end 521. The first connection end 511 is disposed on the first connection surface 51, and is connected to the light guide 30 and is spaced apart from the second light transmissive cover 40. The second connection end 521 is disposed on the second connection surface 52, and is connected to the second light transmissive cover 40. The reflector 50, the light guide 30 and the second light transmissive cover 40 jointly define a light guide cavity 54, and the reflective surface 53 is disposed on the side of the reflector 50 facing the light guide cavity 54. Part of the emitted light generated by the light source module 20 is transmitted into the light guide cavity 54 via the light guide 30, and is reflected by the inner wall surface of the light guide cavity 54 to the second light exit area 401, which can improve the light utilization rate. Further, the second connection end 521 is connected to the reflector, and the light entering the light guide cavity 54 can be reflected to the second light transmissive cover 40 and emitted to different positions of the second light exit area 401, thereby expanding the lighting range of the lamp 100.

[0044] In this embodiment, the reflective surface 53 is the area where the reflective member 50 is used to reflect light, and the reflective surface 53 is arranged on the optical path of part of the light generated by the light source module 20. The reflective surface 53 defines the inner wall surface of the light guide cavity 54, and the light entering the light guide cavity 54 can be reflected to the light exit area via the reflective surface 53. As an example, part of the light generated by the light source module 20 is emitted to the surface of the first light-transmitting cover 10 for reflection, and the reflected light is transmitted to the reflective surface 53 via the light guide 30 and then reflected to the second light-transmitting cover 40. On the one hand, the number of light source modules 20 to be set can be reduced, and the number of installed parts can be reduced, thereby reducing the space volume of the lamp 100 and reducing the production cost; on the other hand, one light source module 20 can provide lighting for two areas, which can increase the lighting range of the lamp 100. Furthermore, part of the light generated by the light source module 20 that deviates from the first light-transmitting cover 10 can be transmitted to the second light-transmitting cover 40 via the light guide 30, and emitted to the area corresponding to the second light-transmitting cover 40, which can improve the light utilization rate. At the same time, the two areas can form a linked lighting effect to enhance the user's visual experience.

[0045] In the present embodiment, the reflective surface 53 is a revolving surface. The revolving surface is formed by rotating an optically designed curve 360 ​​degrees relative to the central axis, and can receive light from the light source module 20 entering the light guide cavity 54 from various angles. Specifically, the central axis of the light source module 20 coincides with the central axis of the reflector 50, so that the outgoing light from the light source module 20 that partially enters the second light-transmitting cover 40 can be emitted to the second light-emitting area 401 after being reflected once by the reflective surface 53, which can reduce the energy loss of the outgoing light caused by multiple reflections, improve the light energy utilization rate of the lamp 100, and thus improve the light utilization rate. In the present embodiment, the revolving surface is a curved surface structure, and the curved surface is basically concave in the direction of the central axis, that is, the reflective surface 53 is a concave surface that forms the outer contour of the reflector 50. The curved surface can be a spherical surface, a spherical surface, an ellipsoidal surface, a free-form surface, or other non-spherical surface, which is not limited in the present embodiment. The provision of the curved surface enables the multiple beams of emitted light generated by the light source module 20 to be reflected to different positions of the second light emitting area 401 through different areas of the reflective surface 53, thereby increasing the illumination range of the lamp 100, or facilitating the realization of an illumination spot of a specific shape by utilizing the light gathering or light diffusion effect of the curved surface / curved surface. In addition, the curved surface can make the light emission more uniform.

[0046] In some embodiments, the revolving surface can also be composed of multiple arc surface segments connected end to end. Specifically, each arc surface segment has multiple small arc surfaces in the radial direction of the reflector 50, which can further increase the surface area of ​​the reflective surface 53, so that it has a certain light dispersion effect, and can make the light spot more uniform. At the same time, the arc surface segments at different positions have different angles relative to the emitted light, so that the surface segments at different positions can receive light emitted at different angles from the light source module 20, increase the lighting range, and ensure the reflection reliability of the reflective surface 53.

[0047] In other embodiments, the reflecting surface 53 may also be a plane. The reflecting surface 53 is tilted relative to the second light-transmitting cover 40, so that part of the emitted light generated by the light source module 20 can be reflected to the second light-emitting area 401 via the reflecting surface 53, thereby increasing the illumination range and illumination brightness of the lamp 100. Specifically, the second light-emitting area 401 is the outer surface of the second light-transmitting cover 40, one end of the reflecting surface 53 is connected to the second light-transmitting cover 40, and the angle between the reflecting surface 53 and the plane where the second light-transmitting cover 40 is located is an acute angle. The above arrangement can reflect part of the emitted light generated by the light source module 20 to the second light-emitting area 401 via the reflecting surface 53. At the same time, part of the emitted light generated by the light source module 20 can be reflected to different positions of the second light-emitting area 401 via different areas of the reflecting surface 53, thereby increasing the illumination range of the light source module 20. As an example, the angle between the reflective surface 53 and the plane where the second light-transmitting cover 40 is located has a value range of 15° to 60° (including the endpoints), for example, the value of the angle between the reflective surface 53 and the plane where the second light-transmitting cover 40 is located can be 15°, 30°, 45°, 60°, etc. It should be noted that the value range of the angle between the light-emitting surface and the plane where the second light-transmitting cover 40 is located can also be other angles, which can be set according to actual application requirements to obtain a specific lighting angle, and this is not limited in this embodiment.

[0048] In other embodiments, the reflective surface 53 may include multiple plane segments. The multiple plane segments are connected in sequence along the light emitting direction. Two adjacent plane segments among the multiple plane segments are arranged at an angle (the angle between the two is less than 180°), so that the plane segments at different positions can receive the outgoing light of the light source module 20 at different angles, thereby increasing the illumination range. At the same time, the outgoing light incident on the plane segment can be reflected to ensure the reflection reliability of the reflective surface 53.

[0049] See also Figure 7In other embodiments, a plurality of closely arranged second surface microstructures 531 are also provided on the reflective surface 53. The second surface microstructures 531 can make the light reflect in different directions when passing through, change the light travel path, achieve sufficient scattering of the light, and achieve a softer and more uniform illumination effect. Among them, the second surface microstructures 531 may include a convex structure or a groove structure, or a rough surface with polygonal convexities or concavities, or a combination of one or more scale patterns or orange peel patterns, etc. The second surface microstructures 531 may also be evenly arranged on the reflective surface 53, or may be arranged at intervals, so as to form a reflective surface 53 that is partially provided with second surface microstructures 531 and partially smooth. As an example, the reflective surface 53 is evenly provided with second surface microstructures 531, and the second surface microstructures 531 are convex structures, each of which is extended along the direction from the first connection end 511 to the second connection end 521, and a plurality of 531 are arranged on the reflective surface 53 in sequence along the circumference of the reflector 50. The light generated by the light source module 20 is transmitted through the light guide 30 into the second light-transmitting cover 40 and emitted from the reflective surface 53. Since the reflective surface 53 has a second surface microstructure 531, the reflected light is reflected in all directions when projected onto the second surface microstructure 531, i.e., diffuse reflection occurs. Diffuse reflection can change the propagation path of the reflected light, so that it is reflected to the second light emitting area 401 along various different directions when it reaches the second surface microstructure 531. Specifically, a part of the reflected light is directly emitted after being reflected by the second surface microstructure 531 of the reflective surface 53; another part of the reflected light reaches another part of the second surface microstructure 531 of the reflective surface 53, continues to be diffusely reflected, and continuously reflects through the second surface microstructure 531 until it is emitted, thereby forming different light emitting effects in the light emitting area.

[0050] In summary, the embodiment of the present application provides a lamp 100, which includes a first light-transmitting cover 10, a second light-transmitting cover 40, and a light source module 20. The first light-transmitting cover 10 is provided with a first accommodating cavity 11 and a first opening 12, and the light source module 20 is arranged in the first accommodating cavity 11. The light generated by the light source module 20 can be directly emitted through the first light-transmitting cover 10 to illuminate the corresponding area. Furthermore, part of the light generated by the light source module 20 can be transmitted to the second light-transmitting cover 40 through the light guide 30. On the one hand, the number of light source modules 20 to be set can be reduced, and the number of installed parts can be reduced, thereby reducing the space volume of the lamp 100 and reducing the production cost; on the other hand, one light source module 20 can provide lighting for two areas, which can increase the lighting range of the lamp 100. At the same time, part of the light generated by the light source module 20 that cannot be emitted through the first light-transmitting cover can be emitted through the second light-transmitting cover and emitted to the area corresponding to the second light-transmitting cover 40, which can improve the light utilization rate and form a linked light-emitting effect in the two areas, further improving the user's visual experience.
