[0028] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of this application

[0029] Please refer to Figure 1 , an embodiment of this application provides a lamp 100. The lamp 100 is used for an illumination application environment or for creating an atmosphere. The lamp 100 may include a lighting lamp, a wall washer lamp, a neon lamp, etc. Classified according to the type of light source, the lamp 100 may include an LED lamp and an incandescent lamp, etc. Classified according to the color of the illumination beam, the lamp 100 may include a natural light lamp, a yellow light lamp, a dazzling light lamp, etc. Classified according to the light intensity of the illumination beam, the lamp 100 may include a strong light lamp and a soft light lamp, etc

[0030] Please refer to Figure 2 and Figure 3, in this embodiment, the lamp 100 includes a housing 11, a light source module 12, and a lampshade 20. The housing 11 has a cavity structure, and the housing 11 is provided with a light-transmitting opening 111 to communicate the interior of the housing 11 with the outside. The light source module 12 is disposed inside the housing 11. The light source module 12 is used to emit a lighting beam, and the lighting beam is conducted out of the housing 11 through the light-transmitting opening 111. The lampshade 20 is connected to the housing 11 and covers the light-transmitting opening 111. The lighting beam is conducted to the lampshade 20 and transmitted through the lampshade 20 to be conducted to the application environment. The lampshade 20 has a softening effect on the lighting beam, so that the light emitted from the lampshade 20 is relatively soft. The lampshade 20 also has a certain scattering effect on the lighting beam to expand the lighting range of the lamp 100. In this embodiment, the lampshade 20 is detachably connected to the housing 11, so that the housing 11 can be separated from the current lampshade 20 and assembled with other different lampshades 20. Specifically, the lamp 100 can be configured with a plurality of lampshades 20, and any one of the plurality of lampshades 20 can be selected and installed on the housing 11. The outer contour of each lampshade 20 is different, so that each lampshade 20 can form a different lighting effect, so that the lamp 100 has more lighting effects.

[0031] Please refer to Figure 2 and Figure 4 , the lamp 100 of this embodiment further includes a light homogenizing member 15. The light homogenizing member 15 is connected to the housing 11 and is located on the side of the light source module 12 facing the light-transmitting opening 111. Before the lighting beam emitted by the light source module 12 is conducted to the outside of the housing 11, it is first conducted to the light homogenizing member 15. The light homogenizing member 15 has a light mixing effect, which can make the lighting beam uniformly diffuse on the light homogenizing member 15, so that the lighting beam transmitted through the light homogenizing member 15 and subjected to the light mixing effect is relatively uniform. In the state where the light homogenizing member 15 and the lampshade 20 are installed on the housing 11, the light homogenizing member 15 is located between the light source module 12 and the lampshade 20. The lighting beam emitted by the light source module 12 is subjected to the light mixing process of the light homogenizing member 15 and then conducted to the lampshade 20, so that the lampshade 20 is uniformly irradiated everywhere, so that the light emitted by the lampshade 20 in the application environment is relatively uniform, reducing the obvious degree of the alternation of light and dark of the lighting effect of the lamp 100 and improving the lighting effect and visual effect of the lamp 100.

[0032] In summary, the lamp 100 provided in this embodiment includes a housing 11, a light source module 12, a light homogenizing member 15, and a lamp cover 20. The housing 11 is provided with a light-transmitting opening 111 to communicate the inside and the outside of the housing 11. The light source module 12 is disposed inside the housing 11. The housing 11 is detachably connected to the lamp cover 20. When the lamp cover 20 and the housing 11 are in a connected state, the lamp cover 20 covers the light-transmitting opening 111, and the illumination beam emitted by the light source module 12 can be conducted to the lamp cover 20. In this embodiment, the housing 11 may be configured with a plurality of lamp covers 20, and the outer contour shapes of the plurality of lamp covers 20 are different from each other. Any one of the lamp covers 20 can be detachably connected to the housing 11. Each lamp cover 20 with a different outer contour shape can form different lighting effects in the application environment under the illumination of the illumination beam, so that the lamp 100 has a variety of lighting effects and improves the application range of the lamp 100.

[0033] In this embodiment, the light homogenizing member 15 is disposed on the housing 11 and is located near the light-transmitting opening 111. The light homogenizing member 15 is located between the light source module 12 and the lamp cover 20. Therefore, in this embodiment, the light homogenizing member 15 is located on the light path of the light source module 12. The illumination beam emitted by the light source module 12 is first conducted to the light homogenizing member 15 before being conducted to the lamp cover 20. The light homogenizing member 15 has a light mixing effect on the illumination beam. The light formed after the illumination beam passes through the light homogenizing member 15 is relatively uniform. The relatively uniform light is conducted to the lamp cover 20 through the light-transmitting opening 111 so that the lamp cover 20 is uniformly illuminated everywhere, enabling the lamp to emit relatively uniform light in the application environment even when different outer contour-shaped lamp covers 20 are used, reducing the relatively bright or relatively dim areas in the lighting effect, and improving the illumination effect and visual effect of the lamp 100.

[0034] Please refer to Figure 5 and Figure 6, in this embodiment, the light homogenizing member 15 is fixedly connected to the housing 11, for example, by welding, connection with fixing members (such as screws, pins, etc.) or gluing. When the light homogenizing member 15 is installed on the housing 11, the light homogenizing member 15 is spaced apart from the light transmissive opening 111 to reserve space for installing the lamp shade 20. In this embodiment, a first mounting groove 112 is provided along the circumferential direction of the inner wall of the housing 11. The first mounting groove 112 is an annular groove body, and the first mounting groove 112 and the light transmissive opening 111 are spaced apart from each other. In this embodiment, the light homogenizing member 15 is generally in a sheet-like structure, including a plastic light homogenizing sheet or a silicone light homogenizing sheet, etc., so that the light homogenizing member 15 is a structure with elastic deformation ability. During the process of assembling the light homogenizing member 15 and the housing 11, a certain external force can be applied to the light homogenizing member 15 to cause it to undergo a small deformation, so that the peripheral structure of the light homogenizing member 15 is embedded in the annular first mounting groove 112. When the light homogenizing member 15 is embedded in the first mounting groove 112, the maximum outer contour of the first mounting groove 112 is arranged around the outer periphery of the outer contour of the light homogenizing member 15 and is spaced apart, that is, the size of the light homogenizing member 15 is smaller than the size of the shape defined by the maximum outer contour of the first mounting groove 112, so as to reduce the difficulty of installing the light homogenizing member 15.

[0035] In this embodiment, the lamp 100 further includes an adhesive colloid (not shown in the figure), and the adhesive colloid is used to bond the light homogenizing member 15 to the housing. Specifically, when the light homogenizing member 15 is in a state of being embedded in the first mounting groove 112, the adhesive colloid is filled at the peripheral structure of the light homogenizing member 15. The adhesive colloid is connected between the peripheral structure of the light homogenizing member 15 and the housing 11 (i.e., the structure near the first mounting groove 112), so that the adhesive colloid is filled at the intersection position between the light homogenizing member 15 and the inner wall of the housing 11 to fixedly connect the light homogenizing member 15 and the housing 11 and improve the structural stability of the light homogenizing member 15.

[0036] In this embodiment, the peripheral structure of the light homogenizing member 15 is embedded in the first mounting groove 112 on the inner wall of the housing 11, so that in the projected image of the lamp 100 along a specified direction (the straight line in the specified direction is perpendicular to the surface of the light homogenizing member 15), the projected contour of the light source module 12 is basically located within the projected contour of the light homogenizing member 15, and the light homogenizing member 15 and the light source module 12 are fully opposite to each other, so that most of the illumination light beams emitted by the light source module 12 are conducted to the light homogenizing member 15 for light mixing processing. And the peripheral structure of the light homogenizing member 15 intersects with the surface where the inner wall of the housing 11 is located, so that the light homogenizing member 15 can better separate the spaces on both sides of the light homogenizing member 15 in the specified direction and prevent the illumination light beam from leaking to the side of the light homogenizing member 15 away from the light source module 12 through the gap between the light homogenizing member 15 and the inner wall surface of the housing 11.

[0037] In this embodiment, the lamp 100 also includes a thermally conductive cup 14, which is arranged inside the shell 11, and the light source module 12 is arranged inside the thermally conductive cup 14. The opening of the thermally conductive cup 14 is oriented in the same direction as the light-transmitting opening 111, so that the illumination light beam emitted by the light source module 12 can be conducted out of the thermally conductive cup 14 and conducted to the light-distributing member 15 mentioned above. In an actual application scenario, the light source module 12 emits an illumination light beam, and the light source module 12 generates heat, which is transferred to the thermally conductive cup 14, and the thermally conductive cup 14 then transfers the heat to the shell 11 so that the heat contacts the air in the application environment, so that the heat is dissipated. Therefore, the thermally conductive cup 14 in this embodiment is fitted with the shell 11, that is, the outer peripheral side wall of the thermally conductive cup 14 is fitted with at least part of the inner wall of the shell 11, so as to improve the heat transfer efficiency between the thermally conductive cup 14 and the shell 11 and promote the dissipation of heat. In this embodiment, the material of the heat-conducting cup 14 may include metal materials with good heat-conducting effect such as aluminum, aluminum alloy, copper, copper alloy, etc. to promote heat dissipation; polymer materials with small mass and high temperature resistance, such as polyether ketone, polyether ketone ketone, high-temperature nylon, etc., may also be selected to reduce the weight of the lamp 100. In this embodiment, the opening of the heat-conducting cup 14 is spaced from the light-transmitting opening 111, so that the inner wall of the housing 11 between the opening of the heat-conducting cup 14 and the light-transmitting opening 111 is exposed, so as to reserve space for installing the light-distributing member 15 and the lampshade 20, and can reduce the material used for the heat-conducting cup 14, thereby reducing the production cost.

[0038] See also Figure 3 and Figure 5 In this embodiment, the light source module 12 includes a light emitting member 121, which is connected to the thermal cup 14, and the light emitting member 121 of the light emitting member 121 faces the light homogenizing member 15. In this embodiment, the light emitting member 121 is located at the opening of the thermal cup 14, so that the heat generated by the light emitting member 121 can be transferred to the housing 11 through the thermal cup 14, and the distance between the light emitting side of the light emitting member 121 and the light homogenizing member 15 can be made smaller, so as to reduce the loss of the illumination light beam during the propagation process to improve the brightness of the lamp 100. In this embodiment, the light source module 12 also includes a control mainboard 122 and an antenna 16, the control mainboard 122 is arranged inside the thermal cup 14, the control mainboard 122 is located on the side of the light emitting member 121 away from the light homogenizing member 15, the control mainboard 122 is electrically connected to the light emitting member 121, and electrical components such as resistors, capacitors, chips, etc. can be welded or plugged on the control mainboard 122 to jointly form a control circuit.

[0039] In this embodiment, the antenna 16 may include an FPC patch antenna. The FPC patch antenna includes an FPC substrate and a radiator. The FPC substrate is attached to the control main board 122 and electrically connected to the control main board 122. The radiator has a fine rod or fine whisker-like structure. The radiator is connected to the FPC substrate and extends out of the heat conduction cup 14 through the opening of the heat conduction cup 14. In this embodiment, the material of the heat conduction cup 14 is a metal with good thermal conductivity. Therefore, the radiator of the antenna 16 needs to extend outside the heat conduction cup 14. The radiator is located between the opening of the heat conduction cup 14 and the light-transmitting opening 111, so as to effectively receive the light effect signals transmitted from the outside (such as remote control, wireless Bluetooth, etc.). And the antenna 16 is spaced from the metal heat conduction cup 14 to prevent the metal heat conduction cup 14 from contacting the antenna 16 and thus affecting the signal transmission of the antenna 16. In this embodiment, the radiator does not penetrate the light homogenizing member 15 to avoid the antenna 16 interfering too much with the propagation of the illumination beam.

[0040] In an actual application scenario, the antenna 16 receives various light effect signals from the outside and transmits the light effect signals to the control main board 122. A control look-up table may be stored in the control main board 122. The control look-up table records multiple light effect signals and multiple light-emitting modes, and the multiple light effect signals and multiple light-emitting modes correspond to each other one by one. The control main board 122 selects the corresponding light-emitting mode according to the light effect signal transmitted by the antenna 16 and the control look-up table, and controls the light-emitting member 121 to emit light in this light-emitting mode.

[0041] Please refer to Figure 3 , in this embodiment, the light-emitting member 121 includes a light source circuit board 1211 and a plurality of lamp beads 1212. The light source circuit board 1211 is embedded at the opening of the heat conduction cup 14. The antenna 16 mentioned above penetrates the light source circuit board 1211 so as to extend outside the heat conduction cup 14. The plurality of lamp beads 1212 are arranged on the side of the light source circuit board 1211 facing the light homogenizing member 15, so that the light source circuit board 1211 is in contact with the heat conduction cup 14 and can conduct heat transfer, and the distance between the lamp beads 1212 and the light homogenizing member 15 is small. In this embodiment, the lamp beads 1212 include LED lamp beads. The LED lamp beads have low energy consumption, generate less heat, and have high luminous efficiency.

[0042] In this embodiment, the lamp 100 further includes a thermal conductive colloid (not shown in the figure), such as silicone thermal conductive adhesive, epoxy resin AB adhesive, polyurethane adhesive, and polyurethane thermal conductive and conductive adhesive. The thermal conductive colloid is disposed inside the thermal conductive cup 14. In an actual application scenario, the thermal conductive colloid fills the inside of the thermal conductive cup 14, so that the control main board 122 is immersed in the thermal conductive colloid, and a part of the structure of the antenna 16 is immersed in the thermal conductive colloid. The thermal transfer efficiency of the thermal conductive colloid is relatively high, and it can effectively transfer the heat generated by the control main board 122 to the housing 11, so that the temperature of the control main board 122 and its nearby structures is relatively low, avoiding damage to the control main board 122 and extending the service life of the control main board 122 and the lamp 100. The light source circuit board 1211 is disposed at the opening of the thermal conductive cup 14, and the side of the light source circuit board 1211 facing away from the light homogenizing plate is attached to the thermal conductive colloid, so that the light source circuit board 1211 is stably connected to the thermal conductive cup 14, and the heat on the light source circuit board 1211 can be quickly absorbed by the thermal conductive colloid and transferred to the housing 11 to timely reduce the heat of the light source circuit board 1211. In some embodiments, the side of the light source circuit board 1211 where the lamp beads 1212 are provided is also filled with the thermal conductive colloid to further improve the structural stability of the light emitting member 121 and reduce the temperature at the light emitting member 121. The thermal conductive colloid in this embodiment is in a solid state and has a certain elasticity after solidification, and can buffer the external impact on the housing 11 and the lamp 100 to protect the components inside the housing 11. In this embodiment, the thermal conductive colloid is an insulating colloid to avoid abnormal electrical connection between the control main board 122, the light emitting member 121, and the metal thermal conductive cup 14, and avoid short circuit of the control main board 122, so that the lamp 100 can work normally.

[0043] Please refer to Figure 1 , in this embodiment, the lamp 100 further includes an electrical connector 13. The electrical connector 13 has a columnar structure, and a thread is provided on the outer periphery of the electrical connector 13. The electrical connector 13 is connected to the side of the housing 11 facing away from the light transmitting opening 111, and the electrical connector 13 is electrically connected to the control main board 122 to form a circuit. In an actual application scenario, an electrical connection socket for power connection is provided in the application environment of the lamp 100. The electrical connection socket includes a metal groove body, and a thread is provided in the groove body. The electrical connector 13 is threadedly connected to the metal groove body to achieve electrical connection, so as to connect the lamp 100 to the power supply.

[0044] Next, the cooperation relationship between the lamp cover 20 and the lamp 100 will be introduced.

[0045] Please refer to Figure 5, in this embodiment, the housing 11 is provided with a mating portion 113, and the mating portion 113 is used for detachably mating and connecting with the lamp cover 20, so that the lamp cover 20 is detachably connected to the housing 11. When the lamp cover 20 is connected to the housing 11, the light homogenizing member 15 is located between the lamp cover 20 and the light source module 12. The illumination beam emitted by the light source module 12 becomes relatively uniform after being mixed by the light homogenizing member 15, and then is conducted to the lamp cover 20 and then to the application environment, so that the brightness of each area of the lighting effect is relatively uniform, reducing the brightness difference between different areas of the lighting effect, reducing the relatively bright or relatively dim areas in the lighting effect, and improving the lighting effect and visual effect of the lamp 100.

[0046] Please refer to Figure 5 , Figure 6 and Figure 7 , in this embodiment, the lamp 100 can be configured with multiple lamp covers 20, and any one of the lamp covers 20 can be selected and installed on the housing 11 to present different lighting effects. In this embodiment, the structural components of the multiple lamp covers 20 are substantially the same, so that each lamp cover 20 can be adapted to the housing 11 and detachably connected. Specifically, each of the multiple lamp covers 20 includes a cover body 22 and a mounting portion 21. In this embodiment, the outer contour of each cover body 22 of the multiple lamp covers 20 is different. For example, the outer contour of the cover body 22 can be in the shape of a water droplet, a sphere, a column, a polyhedron, a frustum of a cone, etc. The lighting effects presented by the cover bodies 22 with different outer contours are different. For example, the propagation direction of light, the brightness of the light spot, the shape of the light spot, etc. The outer contour of the cover body 22 itself affects the lighting effect it presents.

[0047] In some other embodiments, the patterns on the cover bodies 22 with different outer contours can be different (words, images, etc.), or the colors of the cover bodies 22 with different outer contours can be different (red, green, color, etc.), etc., so that each lamp cover 20 has a different lighting effect.

[0048] In this embodiment, the mating portion 113 is disposed on the inner wall of the housing 11. As can be seen from the foregoing, the space reserved between the light homogenizing member 15 and the light transmissive opening 111 is for installing the lamp shade 20. Therefore, the mating portion 113 is located between the first installation groove 112 and the light transmissive opening 111. The installation portion 21 of the lamp shade 20 is connected to the side of the cover body 22 facing the housing 11. During the assembly process, the installation portion 21 extends into the interior of the housing 11 through the light transmissive opening 111 and is detachably connected to the mating portion 113. In the assembled state, at least a part of the structure of the installation portion 21 is accommodated inside the housing 11 and is detachably connected to the mating portion 113. The side of the cover body 22 facing the housing 11 abuts against the edge structure of the light transmissive opening 111, so that the lamp shade 20 and the housing 11 are closely fitted and the connection effect is better. In this embodiment, the outer surface of the cover body 22 and the outer surface of the housing 11 are smoothly continuous, so that there is a smooth transition between the lamp shade 20 and the housing 11, improving the integration degree between the lamp shade 20 and the housing 11, avoiding the abrupt structure of the lamp 100, and making the lamp 100 more beautiful.

[0049] Please refer to Figure 5 、 Figure 6 and Figure 8 In this embodiment, the mating portion 113 includes a second installation groove 1131, and the second installation groove 1131 is located between the first installation groove 112 and the light transmissive opening 111. Correspondingly, the installation portion 21 includes a connecting tube body 211 and an embedded convex block 212. The connecting tube body 211 has a tubular structure. The connecting tube body 211 is connected to the cover body 22 and is in communication with the interior of the cover body 22. The embedded convex block 212 is disposed on the outer periphery of the connecting tube body 211 and protrudes relative to the connecting tube body 211. The extending direction of the embedded convex block 212 is substantially the same as the radial direction of the connecting tube body 211. In this embodiment, the size of the installation portion 21 (the embedded convex block 212 and the connecting tube body 211) is larger than the size of the light transmissive opening 111. The connecting tube body 211 is a structure with elastic deformation ability. During the process of assembling the lamp shade 20 and the housing 11, the connecting tube body 211 can be deformed by an external force, so that both the connecting tube body 211 and the embedded convex block 212 can extend into the interior of the housing 11 through the light transmissive opening 111. When the embedded convex block 212 moves to a position where the embedded convex block 212 is aligned with the second installation groove 1131, the connecting tube body 211 releases the elastic force and pushes the embedded convex block 212 to extend into the second installation groove 1131 to complete the mating connection between the installation portion 21 and the mating portion 113. In the state where the lamp shade 20 and the housing 11 are assembled, the connecting tube body 211 is accommodated inside the housing 11, and the embedded convex block 212 is embedded in the second installation groove 1131 to realize the detachable connection between the lamp shade 20 and the housing 11. In this embodiment, the outer periphery of the connecting tube body 211 is closely attached to the inner periphery of the light transmissive opening 111 to prevent light from leaking through the gap between the connecting tube body 211 and the housing 11.

[0050] In this embodiment, the second installation groove 1131 is an annular groove body. The opening of the annular groove body is relatively simple, which can simplify the production steps of the housing 11. In this embodiment, the connecting pipe body 211, the embedded convex block 212 and the cover body 22 included in the lamp cover 20 are of an integrally formed structure. The material of the lamp cover 20 can be plastic, polyethylene, etc. In other embodiments, the installation part 21 (the connecting pipe body 211 and the embedded convex block 212) and the cover body 22 can be two separate structures. The installation part 21 and the cover body 22 are connected by means such as bonding, snap - fit connection with a snap - groove, and screw - fixed connection. In such embodiments, the material of the installation part 21 is a structure with elastic deformation ability, and the material of the cover body 22 is not limited. As an example, the cover body 22 can be glass, so that when the lamp 100 is in the lighting state, the cover body 22 sparkles crystal - clearly, improving the visual effect of the lamp 100. As another example, the cover body 22 can include a wooden frame and a thin and light fabric. The fabric adheres to the hollow part of the wooden frame, and patterns such as figures, landscapes, flowers, birds, fish and insects are drawn on the fabric, so that the lamp 100 has a traditional Chinese style, making the lamp 100 and the lighting effect of the lamp 100 have high ornamental value.

[0051] Please refer to Figure 6 、 Figure 8 and Figure 9 , in this embodiment, the number of the embedded convex blocks 212 is multiple. The multiple embedded convex blocks 212 are arranged in a circumferential manner at intervals in sequence on the outer periphery of the connecting pipe body 211. The multiple embedded convex blocks 212 are all used for being embedded in the second installation groove 1131, so that the matching relationship between the installation part 21 and the second installation groove 1131 is more stable. Multiple fitting grooves 1133 are concavely provided at multiple places on the inner peripheral edge of the light - transmitting opening 111. The multiple fitting grooves 1133 are arranged in one - to - one correspondence with the multiple embedded convex blocks 212. Each fitting groove 1133 communicates with the second installation groove 1131, and each fitting groove 1133 communicates with the end face of the housing 11 facing the lamp cover 20. In this embodiment, the maximum outer diameter of the fitting groove 1133 is smaller than the maximum outer diameter of the second installation groove 1131. The outer diameter of the embedded convex block 212 is larger than the maximum outer diameter of the fitting groove 1133 and smaller than the maximum outer diameter of the second installation groove 1131. During the assembly process of the installation part 21 and the housing 11, the connecting pipe body 211 is slightly deformed by an external force and then extends into the interior of the housing 11. Each embedded convex block 212 first extends into a corresponding fitting groove 1133 and then continues to move to be embedded in the second installation groove 1131 to complete the assembly of the lamp cover 20 and the housing 11. In this embodiment, by providing the fitting grooves 1133 in the light - transmitting opening 111 and meeting the above - mentioned dimensions, the degree of deformation of the connecting pipe body 211 can be reduced, and the assembly difficulty can be lowered. After the assembly is completed, at least part of the structure of each embedded convex block 212 is embedded in the second installation groove 1131 to ensure the stability of the connection relationship between the lamp cover 20 and the housing 11.

[0052] In this embodiment, a positioning projection 1132 is provided on the inner wall of the second installation groove 1131, and the positioning projection 1132 is exposed through one of the fitting grooves 1133. Correspondingly, a positioning groove is provided on the fitting projection 212 corresponding to the fitting groove 1133. In the state where the lamp cover 20 and the housing 11 are assembled, the positioning groove on the fitting projection 212 is fitted and engaged with the positioning projection 1132 to limit the rotation of the lamp cover 20 relative to the housing 11 around the axis of the connecting pipe body 211, and maintain the stable relative position state of the lamp cover 20 and the housing 11. In this embodiment, at least one positioning projection 1132 is provided, and correspondingly, at least one fitting projection 212 is provided with a positioning groove. In the embodiment where multiple positioning projections 1132 are provided, the positioning grooves on the multiple fitting projections 212 correspond to and are fitted and engaged with the multiple positioning projections 1132 one by one to improve the limiting effect and reduce the wear of the positioning projections 1132 and the positioning grooves.

[0053] In some other embodiments, the lamp cover 20 and the housing 11 can be in threaded engagement. Specifically, the fitting portion 113 includes an internal thread provided on the inner wall of the housing 11, and the internal thread is located between the first installation groove 112 and the light-transmitting opening 111. Correspondingly, an external thread is provided on the outer periphery of the installation portion 21, that is, an external thread is provided on the outer periphery of the connecting pipe body 211. During the assembly of the lamp cover 20 and the housing 11, the housing 11 rotates around the axis of the connecting pipe body 211 to screw the external thread and the internal thread together to install the lamp cover 20 on the housing 11. During the disassembly of the lamp cover 20, the lamp cover 20 can be rotated in the reverse direction to unscrew the external thread and the internal thread until they are separated to disassemble the lamp cover 20 and the housing 11, thereby realizing the detachable connection between the lamp cover 20 and the housing 11.

[0054] This embodiment provides a lighting fixture 100, which includes a housing 11, a light source module 12, a light homogenizing member 15, and a lamp shade 20. The housing 11 is provided with a light-transmitting opening 111 to communicate the inside and outside of the housing 11. The light source module 12 is disposed inside the housing 11. The housing 11 is detachably connected to the lamp shade 20. When the lamp shade 20 is in a connected state with the housing 11, the lamp shade 20 covers the light-transmitting opening 111, and the illumination beam emitted by the light source module 12 can be conducted to the lamp shade 20. In this embodiment, the housing 11 may be configured with multiple lamp shades 20, and the outer contour shapes of the multiple lamp shades 20 are different from each other. Any one of the lamp shades 20 can be detachably connected to the housing 11. Each lamp shade 20 with a different outer contour shape can form different lighting effects in the application environment under the irradiation of the illumination beam, so that the lighting fixture 100 has multiple lighting effects and improves the application range of the lighting fixture 100. In this embodiment, the light homogenizing member 15 is disposed on the housing 11 and is located near the light-transmitting opening 111. The light homogenizing member 15 is located between the light source module 12 and the lamp shade 20. Therefore, in this embodiment, the light homogenizing member 15 is located on the light path of the light source module 12. The illumination beam emitted by the light source module 12 is first conducted to the light homogenizing member 15 before being conducted to the lamp shade 20. The light homogenizing member 15 has a function of mixing light. The light formed after the illumination beam passes through the light homogenizing member 15 is relatively uniform. The relatively uniform light is conducted to the lamp shade 20 through the light-transmitting opening 111 so that the lamp shade 20 is evenly irradiated everywhere, enabling the lighting fixture to emit relatively uniform light in the application environment even when different outer contour-shaped lamp shades 20 are used, reducing the relatively bright or relatively dim areas in the lighting effect, and improving the lighting effect and visual effect of the lighting fixture 100.
