The lamp 100 can be a lighting lamp or an atmosphere lamp. Specifically, it can be used for ceiling lighting, wall lighting, stage decoration lighting, etc.

[0030] See also Figure 2 and Figure 3In one embodiment provided by the present application, the lamp 100 includes a first light-transmitting cover 10, a base 20 and a connector 30. The first light-transmitting cover 10 includes a cover body 11 and a mounting portion 12. The cover body 11 is provided with a receiving cavity 111 and an opening 112. The opening 112 is located at one end of the cover body 11 and communicates with the receiving cavity 111. The mounting portion 12 is disposed at one end of the cover body 11 and surrounds the outer periphery of the opening 112. The mounting portion 12 is provided with a locking groove 121 and a first positioning portion 122. The locking groove 121 is extended along the circumferential direction of the mounting portion 12, and the first positioning portion 122 is disposed in the locking groove 121. The "circumferential direction" mentioned above can be understood as the circumferential direction of the first light-transmitting cover 10, that is, the direction surrounding the opening 112. Specifically, the number of the locking grooves 121 can be multiple, and the multiple locking grooves 121 are arranged at intervals and distributed on the outer peripheral wall of the mounting portion 12, and are recessed from the surface of the mounting portion 12. The base 20 covers the opening 112, and the connecting member 30 is connected to the side of the base 20 facing the opening 112. The connecting member 30 is provided with a fixing portion 31 and a second positioning portion 32, and the fixing portion 31 is accommodated in the locking groove 121 and can move along the extension direction of the locking groove 121, so that the second positioning portion 32 and the first positioning portion 122 are embedded and matched. "Extension direction" can be understood as the direction of the length formed by the locking groove. Among them, the fixing portion 31 can move in the locking groove 121 and be embedded in the locking groove 121, so that the first light-transmitting cover 10 and the base 20 can be fixedly connected. At the same time, the locking groove 121 is extended along the circumferential direction of the mounting portion 12, and the fixing portion 31 can be locked during the movement process, without the need for the user to press or buckle, thereby simplifying the installation steps. The extension setting of the locking groove 121 also plays a certain limiting role, limiting the moving direction of the fixing portion 31, and can prevent the fixing portion 31 from escaping from the locking groove 121 or deviating from the moving direction during the movement. At the same time, the nested cooperation of the fixing portion 31 and the locking groove 121 can realize quick disassembly and assembly without destroying the first light-transmitting cover 10 or the base 20, which can save the use cost and improve the efficiency of disassembly and assembly maintenance. Furthermore, a first positioning portion 122 is also provided in the locking groove 121, and a second positioning portion 32 is provided on the connecting member 30, and the first positioning portion 122 and the second positioning portion 32 are embedded and matched. On the one hand, the provision of the first positioning portion 122 and the second positioning portion 32 can further improve the connection stability between the first light-transmitting cover 10 and the base 20 and reduce the occurrence of the tripping phenomenon; on the other hand, it can play a role in positioning. When the fixing portion 31 moves to a certain position in the locking groove 121, the first positioning portion 122 and the second positioning portion 32 are embedded and feedback tactile information to the user, thereby improving the user's feel.

[0031] Next, each component of the optical device and the specific structure of each component will be introduced one by one.

[0032] See also Figure 2 and Figure 3In this embodiment, the first light-transmitting cover 10 forms a first light-emitting area. The first light-emitting area extends from the outer wall of the first light-transmitting cover 10. The first light-transmitting cover 10 includes a cover body 11, and the cover body 11 is provided with a receiving cavity 111 and an opening 112. The opening 112 is located at one end of the cover body 11 and communicates with the receiving cavity 111. The interior of the receiving cavity 111 is used to install components, and the components may be a light source, a heat sink, and the like. The material of the first light-transmitting cover 10 may include ABS plastic, PC plastic, or other hard plastics, which can not only reduce the weight of the first light-transmitting cover 10 to achieve lightweight, but also enable the first light-transmitting cover 10 to have a certain stability, thereby effectively protecting the components inside the receiving cavity 111. 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 1010 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 first light-transmitting cover 10 can be provided with a light source module 40, and the light generated by the light source module 40 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, the first light-transmitting cover 10 is provided with a rounded structure 113 on the side facing away from the outlet 112, and the light can be reflected to different parts of the first light-emitting area through the rounded structure 113, which can avoid the light from gathering at the corner and reduce the light from being emitted to the non-illuminated area or non-decorative area, which can improve the light utilization rate and further increase the lighting range or decorative area.

[0033] In this embodiment, the light source module 40 is arranged in the accommodating cavity 111 formed by the first light-transmitting cover 10, and the light source module 40 is used to generate light and emit light to the illumination area. In this embodiment, the light source module 40 includes a plurality of light-emitting units 41 and a support column 42, and the light-emitting unit 41 is detachably mounted on the support column 42, which is convenient for the maintenance and replacement of the light source module 40. Specifically, the support column 42 is used as a mounting carrier of the light-emitting unit 41, which is arranged in the accommodating cavity 111 and is spaced apart from the inner surface of the first light-transmitting cover 10. When the lamp 100 is placed in normal use, the support column 42 has a bottom end and a top end that are separated from each other, the bottom end is connected to the base 20, and the top end extends to the side of the first light-transmitting cover 10 away from the opening 112. The light-emitting unit 41 can cover the outer surface of the support column 42, which is convenient for expanding the light-emitting area and improving the uniformity of light output. The light source module 40 also includes a plurality of first connecting parts 421, which are arranged on the inner surface of the support column 42 and are located at one end of the support column 42 away from the opening 112. As an example, the first connecting portion 421 is a connecting groove, and a plurality of connecting through holes 114 are further provided at one end of the first light-transmitting cover 10 facing away from the opening 112, and the plurality of connecting through holes 114 are arranged in a one-to-one correspondence with the plurality of connecting grooves. The lamp 100 also includes a first fastener 115, and the first fastener 115 can be a screw or a bolt. The first fastener 115 passes through the connecting through hole 114 and is connected to the connecting groove, thereby fixing the first light-transmitting cover 10 and the light source module 40, not only serving as a fixed component, but also serving as a structural reinforcement rib to stabilize the overall structural strength of the support column 42. In addition, the first connecting portion 421 is arranged on the inner surface of the support column 42, so as not to occupy the light-emitting position of the light-emitting unit 41, thereby improving the lighting brightness and achieving a more linear light-emitting effect, thereby improving the user's visual experience.

[0034] In this embodiment, a plurality of light-emitting units 41 are arranged at intervals on the outer wall surface of the support column 42. Therefore, the light source module 40 can emit light at all angles, and the light generated by the light source module 40 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 41 is an incoherent light source, and the light-emitting unit 41 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 41 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 41 are arranged at intervals on a flexible circuit board, and the flexible circuit board is mounted on the outer wall surface of the support column 42. The flexible circuit board 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 41 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.

[0035] See also Figures 3 to 5 In this embodiment, the base 20 and the first light-transmitting cover 10 are basically stacked. Specifically, the base 20 covers the opening 112, which is used to support the mounting surface and provide support to the lamp 100 to keep the overall position of the lamp 100 stable. The mounting surface may be the ground, a desktop or other supporting platform. In order to further enhance the stability of the lamp 100, in some embodiments, the base 20 is also provided with a stabilizing member, which may be a counterweight or a bolt fixing. As an example, the counterweight may add weight to the base 20 to prevent the lamp 100 from tipping over during use. The counterweight may be disposed inside the base 20 or outside the base 20, and this embodiment does not limit this.

[0036] In the present embodiment, the base 20 may further include a second light-transmitting cover 21, and the second light-transmitting cover 21 can form a second light-emitting area. As an example, the second light-transmitting cover 21 is a cylindrical light-transmitting cover, and the light generated by the light source module 40 forms a cylindrical rod light effect on the outer wall of the second light-transmitting cover 21, 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 21 is much smaller than the length of the first head light, so that the light effect formed by the first light-emitting area and the second light-emitting area has a significant difference, and the light effect is more flexible and rich. In the present embodiment, the second light-transmitting cover 21 and the first light-transmitting cover 10 are basically stacked, for example, the intermediate connecting member 30 can be used to achieve stacking. In the present embodiment, the second light-transmitting cover 21 is arranged on the side of the first light-transmitting cover 10 where the opening 112 is provided. The second light-emitting area extends from the outer wall of the second light-transmitting cover 21, and the first light-emitting area and the second light-emitting area are connected along the projection of the specified direction, forming a lighting effect without dark areas and linkage light-emitting. The "specified direction" mentioned above can be understood as the direction of the length of the light source module 40. Part of the emitted light generated by the light source module 40 is transmitted to the inner wall of the first light-transmitting cover 10 for reflection and then emitted to the second light-emitting area through the second light-transmitting cover 21. On the one hand, it can improve the lighting brightness and the utilization rate of light; on the other hand, a single light source module 40 can be used to achieve the light effect of 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 40 and the number of installed parts, thereby reducing the space volume of the lamp 100 and reducing the production cost.

[0037] The material of the second light-transmitting cover 21 may include ABS plastic, PC plastic or other hard plastic, which can not only reduce the weight of the base 20 to achieve lightweight, but also improve the stability of the base 20, thereby effectively protecting the components inside the base 20. 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 21 can also be a light-transmitting material such as light-transmitting glass and acrylic board, which is not limited in this embodiment.

[0038] In order to improve the light emitting effect of the first light emitting area and the second light emitting area, the materials and colors selected for the second light transparent cover 21 and the first light transparent cover 10 may be different. For example, the color of the second light transparent cover 21 is blue, and the color of the first light transparent cover 10 is red. When the light generated by the light source module 40 is emitted through the first light transparent cover 10 and the second light transparent cover 21 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 transparent covers 21 can be multiple. When installed and used, multiple second light transparent covers 21 are stacked and formed to form a second light transparent area 401. Different numbers of second light transparent covers 21 can be superimposed according to the size of the area of ​​the lighting area or the decorative area. The material color of different numbers of second light transparent covers 21 may also be different, thereby forming a colorful light emitting effect and improving the user's visual experience.

[0039] As another example, the material of the second light-transmitting cover 21 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 21 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 21, 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 second light-transmitting covers 21 may be multiple. When installed and used, multiple second light-transmitting covers 21 are stacked and formed to form a second light-transmitting area, and different numbers of second light-transmitting covers 21 may 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 21 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 40 is set, which can reduce the installation of parts, thereby reducing the space volume of the lamp 100 and reducing production costs.

[0040] See also Figure 6 and Figure 7In this embodiment, in order to make the connection between the first light-transmitting cover 10 and the base 20 tight and easy to disassemble and install, and at the same time form a good light-emitting effect, the first light-transmitting cover 10 also includes a mounting portion 12, and the mounting portion 12 and the connecting member 30 are embedded and matched. Specifically, the mounting portion 12 is arranged at one end of the cover body 11 and surrounds the outer periphery of the opening 112. The mounting portion 12 and the cover body 11 are integrally formed, which can reduce the assembly steps and improve production efficiency. In this embodiment, the connecting member 30 is connected to one end of the base 20 facing the opening 112, and is specifically arranged between the base 20 and the first light-transmitting cover 10. The connecting member 30 is used to achieve a tight connection between the base 20 and the first light-transmitting cover 10. Specifically, the connecting member 30 is roughly cylindrical and is suitable for matching the size of the base 20 or the first light-transmitting cover 10. The connecting member 30 is provided with a fixing portion 31, and the mounting portion 12 is provided with a locking groove 121. The fixing portion 31 can be accommodated in the locking groove 121 and move along the extension direction of the locking groove 121. When the fixing portion 31 moves to the extreme position of the locking groove 121, the fixing portion 31 is fastened in the locking groove 121 to achieve a fastened connection between the first light-transmitting cover 10 and the base 20.

[0041] See also Figure 8 Specifically, the connecting member 30 includes an inner peripheral wall 301 facing the mounting portion 12, and the fixing portion 31 is disposed on the inner peripheral wall 301 and protrudes relative to the inner peripheral wall 301. The locking groove 121 is extended along the circumference of the mounting portion 12, and the locking groove 121 includes a first groove portion 1211 and a second groove portion 1212, and the second groove portion 1212 is connected to one end of the first groove portion 1211. The first groove portion 1211 is used for the fixing portion 31 to be inserted into the locking groove 121. Specifically, the first groove portion 1211 penetrates the side of the mounting portion 12 facing the base 20 and forms a notch. When installed and used, the connecting member 30 surrounds the mounting portion 12, and the fixing portion 31 protrudes toward the locking groove 121, and moves between the first groove portion 1211 and the second groove portion 1212 after entering the first groove portion 1211 through the notch. When the fixing portion 31 moves to a certain position, the fixing portion 31 is embedded in the second groove 1212 , thereby achieving the fixation of the first light-transmitting cover 10 and the base 20 .

[0042] In order to further improve the connection and fastening between the first light-transmitting cover 10 and the base 20, the width of the second groove 1212 gradually decreases in the direction away from the first groove 1211. Specifically, the second groove 1212 has a first side wall 1213 and a second side wall 1214 that are spaced apart from each other. The first side wall 1213 and the second side wall 1214 are spaced apart from each other. The first side wall 1213 can be extended along the circumference of the mounting portion 12, and the second side wall 1214 can be extended along the radial direction of the mounting portion 12. The first side wall 1213 can be an inclined surface, and the inclined surface can be a plane inclined relative to the plane where the cross section of the base 20 is located. For example, the angle between the inclined plane and the plane where the cross section of the base 20 is located is less than 90 degrees; the second side wall 1214 can be a straight surface, which can be vertically arranged relative to the plane where the cross section of the base 20 is located, and the angle between the plane where the first side wall 1213 is located and the plane where the second side wall 1214 is located is an acute angle. The first side wall 1213 is used for interference fit with the fixing part 31, and the side wall of the fixing part 31 moves in contact with the first side wall 1213. Since the first side wall 1213 has a certain inclination angle, the fixing part 31 is gradually clamped during the movement until it abuts against the second side wall 1214 or is fixed in the second groove 1212, thereby further improving the connection tightness between the first light-transmitting cover 10 and the base 20. As an example, the acute angle between the plane where the first side wall 1213 is located and the plane where the second side wall 1214 is located is in the range of 3° to 20° (including the endpoints), for example, the acute angle can be 3°, 5°, 10°, 20°, etc. It should be noted that the angle between the plane where the first side wall 1213 is located and the plane where the second side wall 1214 is located can also be in the range of other angles, which is not limited in this embodiment.

[0043] See also Figure 8In this embodiment, the first light-transmitting cover 10 is further provided with a first positioning portion 122, and the connecting member 30 is further provided with a second positioning portion 32, and the first positioning portion 122 and the second positioning portion 32 are embedded and matched. Specifically, the first positioning portion 122 is arranged on the mounting portion 12 and is located at the second groove portion 1212, and the second positioning portion 32 is arranged on the fixing portion 31. When the fixing portion 31 moves to a certain position in the locking groove 121, the second positioning portion 32 and the first positioning portion 122 are abutted against each other. As an example, the first positioning portion 122 can be arranged on the first side wall 1213 or on the second side wall 1214, and the second positioning portion 32 can be located at a corresponding position of the fixing portion 31. One of the first positioning portion 122 and the second positioning portion 32 can be a groove structure, and the other can be a protrusion structure. The nested cooperation of the groove structure and the protrusion structure can further improve the connection stability of the first light-transmitting cover 10 and the base 20, and reduce the occurrence of the tripping phenomenon. At the same time, the first positioning portion 122 and the second positioning portion 32 can play a positioning role. When the fixing portion 31 moves to a certain position in the locking groove 121, the first positioning portion 122 and the second positioning portion 32 are embedded and feedback the touch to the user, thereby improving the user's use feel.

[0044] See also Fig. 9 In order to improve the stability of the lamp 100, the connector 30 is also provided with a plurality of countersunk through holes 33. The plurality of countersunk through holes 33 penetrate the connector 30 and the base 20 at the same time, and the light source module 40 is also provided with a plurality of second connecting parts 116, which are arranged on the inner surface of the support column 42 and along the extension direction of the support column. As an example, when the lamp 100 is in normal use, the support column 42 has a top end and a bottom end that are separated from each other, and the bottom end is mounted on the mounting portion 12. The distance between the top end and the bottom end defines the height of the support column 42, and the second connecting part 116 extends from the top end to the bottom end along the height direction of the support column 42. The second connecting part 116 can be a connecting column, and the plurality of connecting columns and the plurality of countersunk through holes 33 are arranged one by one. The lamp 100 also includes a second fastener 117, which can be a screw or a bolt. The second fastener 117 passes through the countersunk through hole 33 and is connected to the connecting column, thereby fixing the light source module 40, the connecting member 30 and the base 20, and can play the role of fixing parts, and also serve as a structural reinforcement rib to stabilize the overall structural strength of the support column 42. In addition, the second connecting portion 116 is arranged on the inner surface of the support column 42, and can not occupy the light-emitting position of the light-emitting unit 41, thereby improving the lighting brightness and achieving a more uniform light-emitting effect, thereby improving the user's visual experience.

[0045] Please refer again Figure 3In some embodiments, the connector 30 may be made of a light-transmitting material, so the peripheral wall 302 of the connector 30 may also be used for light transmission, so that the light generated by the light source module 40 is emitted through the peripheral wall 33 to form a third light-transmitting area. The peripheral wall 302 is away from the mounting portion 12 and is located between the base 20 and the cover body 11. The peripheral wall 302, the outer surface of the base 20, and the outer surface of the cover body 11 are successively connected flush, 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. And form a light effect of the first light-transmitting area, the second light-transmitting area, and the third light-transmitting area emitting light in conjunction. At the same time, there is no dark area at the outer contour of the lamp 100, and the uniform light emission at each connection, and the formation of a smooth and continuous light effect, can improve the user's visual experience. In order to further enrich the light-emitting effect, the materials and colors of the connector 30, the first light-transmitting cover 10, and the second light-transmitting cover 21 can be different.

[0046] As an example, at least one of the materials of the peripheral wall 302, the outer surface of the first light-transmitting cover 10, and the outer surface of the second light-transmitting cover 21 is different from the materials of the other two. Specifically, it can be translucent glass, transparent plastic, acrylic plate, etc., which is not limited in this embodiment. It is also possible to select the same material with different light transmittances, and the light passing through the materials with different light transmittances can form light effects with different brightness 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 peripheral wall 302, the outer surface of the first light-transmitting cover 10, and the outer surface of the second light-transmitting cover 21 is different from the colors of the other two. The light source module 4020 emits through areas of different colors to form a colorful illumination effect, which can form a variety of light effect lighting and improve the user's visual experience.

Thereby, a fixed connection between the first light-transmitting cover 10 and the base 20 can be achieved. At the same time, the locking groove 121 is extended along the circumferential direction of the mounting portion 12, and the fixing portion 31 can be locked during the movement process, without the need for the user to press or buckle, thereby simplifying the installation steps. The extended setting of the locking groove 121 also plays a certain limiting role, limiting the moving direction of the fixing portion 31, and can prevent the fixing portion 31 from escaping from the locking groove 121 or deviating from the moving direction during the movement. At the same time, the nested cooperation of the fixing portion 31 and the locking groove 121 can realize quick disassembly and assembly without destroying the first light-transmitting cover 10 or the base 20, which can save the use cost and improve the efficiency of disassembly and assembly maintenance. Furthermore, a first positioning portion 122 is also provided in the locking groove 121, and a second positioning portion 32 is provided on the connecting member 30, and the first positioning portion 122 and the second positioning portion 32 are embedded and matched.
