Furthermore, the complex structural design of decorative lighting fixtures also presents challenges for assembly and disassembly.

[0004] In view of this, it is indeed necessary to improve the existing decorative lighting fixtures to solve the above problems. Utility Model Content

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Please see Figure 1 As shown, this utility model discloses a lamp 100, preferably a floor lamp. It includes a main lighting module 10, an auxiliary lighting module 20, and a base module 30. The lamp 100 of this utility model can not only achieve 360° uniform light output from the main lighting module 10, but also facilitates assembly and disassembly through its modular design.

[0039] The main lighting module 10 is capable of circumferential light emission. The auxiliary lighting module 20 is mounted on the first end of the main lighting module 10, i.e. Figure 1 The top of the luminaire 100 is capable of axial light emission. When the luminaire 100 is used in an indoor environment, the auxiliary lighting module 20 can project light onto the mounting base such as the indoor ceiling or suspended ceiling to form a light spot, thereby enhancing the decorative atmosphere of the environment. The base module 30 is assembled at the second end of the main lighting module 10, i.e. Figure 1 The bottom of the luminaire 100 is used to fix and support the main lighting module 10.

[0040] like Figure 6 As shown, the main lighting module 10 includes a main light source assembly. The main light source assembly includes a light source element 11, a light mixing element 12 surrounding the light source element 11, and a diffuser element 13 surrounding the light mixing element 12. The light mixing element 12 and the diffuser element 13 can mix the light emitted from the light source element 11 twice, thereby forming a uniform light emission effect on the outer peripheral wall of the diffuser element 13.

[0041] like Figure 7 As shown, the light source component 11 includes a mounting post 111 and an LED light source flexible board 112 mounted on the mounting post 111. In this embodiment, the light source component 11 is a four-sided prism structure. That is, the mounting post 111 is a quadrangular prism with four mounting surfaces 113 located on different planes, and the LED light source flexible board 112 surrounds the outside of the four mounting surfaces 113. The LED light source flexible board 112 is preferably fixed to the mounting post 111 by adhesive backing so that the heat of the LED light source flexible board 112 can be transferred to the mounting post 111 for heat dissipation.

[0042] The LED light source flexible circuit board 112 is preferably an FPC flexible circuit board, and a plurality of LED light sources 114 are arranged along the extension direction of each mounting surface 113 on the LED light source flexible circuit board 112. After the LED light source flexible circuit board 112 is fixed, it becomes a tetrahedral light column. This arrangement allows the main light source assembly to form a 360° surrounding cylindrical light source for circumferential light emission. Of course, in other optional embodiments, the light source component 11 can also be set as a triangular prism, cylinder, or other cylindrical structure, and there is no limitation on this.

[0043] like Figure 6 As shown, the light mixing element 12 has a light source cavity (not labeled) formed by at least two light-emitting portions 121 and a connecting portion 122 connecting each adjacent pair of light-emitting portions 121. The light source element 11 is housed in the light source cavity, which can achieve a uniform light emission effect of the main light source assembly in a relatively small size. The light mixing element 12 is arranged correspondingly to the light source element 11. The light source element 11 has four light-emitting surfaces located on different planes, and each light-emitting surface is correspondingly arranged with a light-emitting portion 121. That is, a light-emitting portion 121 faces a row of LED light sources 114 on the mounting post 111, so that each light-emitting surface of the LED light source 114 has a light-emitting portion 121 corresponding to it. The connecting portion 122 is arranged between two adjacent rows of LED light sources 114, that is, the connecting portion 122 is located at the corner of the LED light source flexible board 112. The light emitted from the light source 11 is deflected by the light-emitting part 121 and the connecting part 122 before being emitted, and the light emitted through the connecting part 122 converges on the outside of the connecting part 122.

[0044] Specifically, the light-mixing element 12 is integrally formed from a transparent material doped with diffusion particles. The light-emitting portion 121 and the connecting portion 122 are smoothly connected, both protruding towards the side opposite to the light source cavity. In this embodiment, the light-emitting portion 121 protrudes relative to the light source element 11 at a first distance along the optical axis, and the connecting portion 122 protrudes between two adjacent light-emitting portions 121 at a second distance, with the first distance being greater than the second distance, so that one end face of the light-mixing element 12 is formed into a four-petaled flower-shaped structure symmetrical about the center. Of course, in other optional embodiments, the first distance can also be equal to the second distance to meet specific light distribution requirements.

[0045] It is understood that the light mixing element 12 has a central axis perpendicular to the optical axis. The distance from the vertex of the light emitting portion 121 to the central axis is greater than the distance from the vertex of the connecting portion 122 to the central axis. The light mixing element 12 is formed by stretching along the central axis direction, and the stretching length is adjusted according to the length of the light source element 11. In this embodiment, the wall thickness of the light emitting portion 121 and the connecting portion 122 is the same, which is beneficial to reduce the manufacturing difficulty of the light mixing element 12 while ensuring its accuracy.

[0046] Preferably, the projections of the first light-incident surface 1211 and the first light-emitting surface 1212 of any light-emitting portion 121 onto the direction perpendicular to the optical axis are two equidistant parabolic segments. This arrangement results in the light source cavity including a cavity 1213 enclosed by the first light-incident surface 1211. The emitting surface of the LED light source 114 faces the opening of the cavity 1213, and the LED light source 114 is precisely accommodated at the opening of the cavity 1213. In other words, the light-emitting portion 121 covers the emitting surface of the LED light source 114. The projections of the second light-incident surface 1221 and the second light-emitting surface 1222 of the connecting portion 122 onto the direction perpendicular to the optical axis are two equidistant circular rings, the ends of which extend to form gradually flattening straight lines. These rings are directly opposite the corner of the mounting post 111, and are preferably 1 / 4 of a ring.

[0047] This configuration ensures that over 90% of the light emitted by the LED light source 114 is incident on the first light-incident surface 1211, deflected, and emitted from the first light-emitting surface 1212 towards both sides of the corresponding light-emitting portion 121, thereby reducing the energy intensity of the LED light source 114 in the optical axis direction. Of this portion of light, the smaller-angle, higher-energy portion is deflected at a larger angle to both sides of the light-emitting portion 121, while the larger-angle, lower-energy portion is deflected at a smaller angle to both sides of the light-emitting portion 121. The remaining light emitted by the LED light source 114 is incident on the second light-incident surface 1221, deflected, and emitted from the second light-emitting surface 1222 towards the center of the corresponding connecting portion 122, where the connecting portion 122 provides a slight converging effect.

[0048] A light mixing cavity 131 is formed between the diffuser element 13 and the light mixing element 12. Preferably, in this embodiment, the diffuser element 13 can be disposed on the circumferential outer side of the light mixing element 12 in a non-contact manner. In other alternative embodiments, the diffuser element 13 can also be disposed on the circumferential outer side of the light mixing element 12 in contact with the light emitting part 121.

[0049] Furthermore, the distance between the diffuser element 13 and the light mixing element 12 can be adjusted according to specific circumstances, and there are no restrictions on this. A diffusion layer (not shown) is provided on the inner peripheral wall of the diffuser element 13, which is used to diffuse the light emitted through the light mixing element 12. The light emitted from the light source 11 enters the light mixing cavity 131 through the light mixing element 12 and exits from the diffuser element 13. The arrangement of the diffuser element 13 makes the 360° light output formed by the light source 11 more uniform, and the brightness uniformity of the surface of the diffuser element 13 can reach over 98%, with no obvious difference between light and dark areas.

[0050] Specifically, the diffusion element 13 is preferably an annular cylindrical glass tube with a transparent substrate. The diffusion layer is preferably a milky white paint sprayed on the inner surface of the glass tube. The outer surface of the glass tube is not treated, and the milky white paint plays a diffusion role.

[0051] This invention utilizes a light-mixing element 12 to perform a primary light mixing, deflecting the light rays along the optical axis of the LED light source 114 to both sides, thus supplementing the energy at the junction of two adjacent rows of LED light sources 114. A secondary light mixing is then performed using a diffusion element 13, resulting in a more uniform 360° light output from the light source 11. Ultimately, this forms a uniform, continuous cylindrical surface light source without significant brightness abrupt changes on the glass tube wall. Compared to current cylindrical multi-faceted light source boards, this reduces the number of light source boards and installation costs.

[0052] like Figures 2-5 as well as Figure 8 As shown, the main lighting module 10 also includes a first housing 14 surrounding the diffuser element 13, and an upper cover 15 and a lower cover 16 located at both ends of the first housing 14. The upper cover 15 and the lower cover 16 are fixedly connected to the light source element 11 by fasteners such as screws, and the light mixing element 12 and the diffuser element 13 are confined between the upper cover 15 and the lower cover 16. The first housing 14 is preferably a transparent annular cylindrical glass tube, which can make the overall light output quality of the main lighting module 10 stronger. Both the upper cover 15 and the lower cover 16 are disc structures, and the fasteners pass through the end face of the mounting post 111 and enter the mounting post 111 to realize the fixed connection between the upper cover 15 and the lower cover 16 and the mounting post 111.

[0053] The main lighting module 10 also includes a mounting base 17 fixedly connected to the lower cover 16. The mounting base 17 is connected to the side of the lower cover 16 opposite to the upper cover 15 by fasteners such as screws passing through it. In this embodiment, the first housing 14 is positioned between the upper cover 15 and the mounting base 17. That is, the edge of the upper cover 15 extends to the outside of the first housing 14, and one end of both the diffuser element 13 and the first housing 14 abuts against the upper cover 15. The lower cover 16 extends to the outside of the diffuser element 13 and abuts against the other end of the diffuser element 13, while the other end of the first housing 14 abuts against the mounting base 17. Preferably, both ends of the diffuser element 13 and the first housing 14 are respectively provided with buffer rings 18, which are located between the diffuser element 13 and the first housing 14 and the upper cover 15, the lower cover 16, and the mounting base 17. Optionally, the buffer rings 18 are made of silicone rubber to prevent the glass components from contacting and pressing against each other, which could cause the glass to break.

[0054] The fixing base 17 has a frustum-shaped structure, and two concentric annular protrusions 171 with different radii are provided on the side of the fixing base 17 facing the lower cover 16. These protrusions support the lower cover 16 and limit the ends of the diffusion element 13 and the first housing 14 between the two annular protrusions 171 by the buffer ring 18, thereby fixing the diffusion element 13 and the first housing 14.

[0055] The main lighting module 10 also includes multiple adapter plates for power supply. Specifically, the main lighting module 10 includes a first adapter plate 191 located between the upper cover 15 and the light source 11, a fourth adapter plate 192 located between the lower cover 16 and the light source 11, and a second adapter plate 193 located on the side of the mounting base 17 opposite to the lower cover 16. The second adapter plate 193 is used to obtain power from the base module 30 and is also connected to the fourth adapter plate 192 via a wire. The two ends of the LED light source flexible circuit board 112 are respectively welded to the first adapter plate 191 and the fourth adapter plate 192 to achieve power supply. Preferably, the first adapter plate 191 and the fourth adapter plate 192 are provided with through holes for fasteners to pass through, so as to fix the first adapter plate 191 and the fourth adapter plate 192 after the upper cover 15 and the lower cover 16 are fixed. The two ends of the light mixing element 12 abut against the first adapter plate 191 and the fourth adapter plate 192 respectively.

[0056] In one optional embodiment, multiple LED light source flexible circuit boards 112 can be sequentially arranged around the mounting post 111. Each LED light source flexible circuit board 112 has a control chip and electronic components on its back, enabling control of each LED light source flexible circuit board 112 and electrical connection of multiple LED light source flexible circuit boards 112. Heat dissipation and insulation between the control chip and electronic components and the mounting post 111 can be achieved by using a thermal pad. After the lamp 100 is powered on, it can be controlled via mobile phone software to switch the color temperature of multiple LED light source flexible circuit boards 112 between 1800K and 12000K, and to achieve effects such as gradation and flow. This enhances the human-computer interaction, enables flexible color control, and allows the lamp 100 to be integrated into the home environment more harmoniously and practically.

[0057] Preferably, multiple lampshades 141 can be fitted onto the outside of the first housing 14, with each lampshade 141 corresponding to a one-to-one LED light source flexible board 112, enriching the visual experience. The lampshades 141 are preferably made of transparent glass, and the multiple lampshades 141 are connected by buffer rings 142 to prevent the glass from breaking under pressure. Of course, in other optional embodiments, the lampshades 141 can also be made of other transparent materials, and there is no limitation on this. The lampshades 141 at both ends abut against the buffer rings 18 of the first housing 14, and are limited in position by the upper cover 15 and the fixing seat 17.

[0058] It is important to emphasize that this main lighting module 10 is not limited to existing floor lamps; it can also be applied to other types of lighting fixtures such as table lamps, ceiling lights, and pendant lights. Furthermore, the control method is not limited to current mobile phone software control; it can also be combined with various sensors such as gravity sensors, touch sensors, and TOF sensors to achieve lighting control.

[0059] like Figures 8-10As shown, the auxiliary lighting module 20 is connected to the upper cover 15. The auxiliary lighting module 20 includes an auxiliary light source assembly and a second housing 21 that houses the auxiliary light source assembly. The second housing 21 is a cylindrical structure with one open end and a stepped structure on its outer peripheral wall. The center of the upper cover 15 protrudes towards the light source 11, thereby forming a receiving groove 151 on the side of the upper cover 15 facing the second housing 21. The second housing 21 is partially housed in the receiving groove 151, and its stepped structure abuts against the upper cover 15. The upper cover 15 has a protruding latching part 152 on the side facing the second housing 21, and the second housing 21 has a corresponding mating part 211 adapted to the latching part 152. The mating part 211 and the latching part 152 are configured to rotatably connect the second housing 21 and the upper cover 15.

[0060] In this embodiment, the latching part 152 is a hook fixed to the bottom of the receiving groove 151, and the mating part 211 is a slot formed at the bottom of the second housing 21. The hook can extend into the slot, and by rotating the second housing 21 clockwise, the hook slides along the slot until it is fixed in place, thus securing the hook in the slot and fixing the second housing 21 to the upper cover 15. Preferably, two sets of hooks and slots are provided to ensure a stable connection. In other optional embodiments, the latching part 152 can be a slot provided on the upper cover 15, and the corresponding mating part 211 can be a hook provided on the second housing 21; this is not limited.

[0061] The auxiliary light source assembly includes a light source plate 22, a reflector 23 located in the light emission direction of the light source plate 22, and a diffuser plate 24 located between the light source plate 22 and the reflector 23. The light source plate 22 is fixedly connected to the bottom of the second housing 21. The diffuser plate 24 is supported inside the second housing 21 and located in the light emission direction of the light source plate 22. The reflector 23 is snapped into the opening of the second housing 21. Thus, the diffuser plate 24 and the reflector 23 achieve axial ambient lighting of the auxiliary light source assembly. The light source plate 22 is provided with a spring pin 221 protruding towards the first adapter plate 191. The spring pin 221 extends out of the second housing 21, and the first adapter plate 191 is partially exposed to the top cover 15. The spring pin 221 is configured to pass through the second housing 21 and the top cover 15 and elastically abut against the first adapter plate 191 to provide power to the light source plate 22. It is understandable that while the second housing 21 is fixedly connected to the upper cover 15, the spring pin 221 abuts against the first adapter plate 191, that is, the auxiliary lighting module 20 is simultaneously connected mechanically and electrically.

[0062] like Figure 11As shown, the base module 30 is connected to the fixing seat 17. The base module 30 includes a third housing 31 and a third adapter plate 32 located within the third housing 31. The fixing seat 17 is connected to the third housing 31 and supplies power to the main lighting module through the third adapter plate 32. A fixing groove 311 is provided at the center of the third housing 31. The third adapter plate 32 has a pin protruding towards the second adapter plate 193. The pin extends into the fixing groove 311 and is partially exposed within it. When the fixing seat 17 is installed in the fixing groove, the second adapter plate 193 abuts against the pin. The second adapter plate 193 and the third adapter plate 32 are electrically connected to supply power to the main lighting module 10 and the auxiliary lighting module 20. The third housing 31 also contains a counterweight and a control box to ensure the stability of the entire lamp and to control the switching of the main lighting module 10 and the auxiliary lighting module 20.

[0063] In summary, the lamp 100 of this utility model, by comprising a main lighting module 10, an auxiliary lighting module 20, and a base module 30, achieves a modular design, facilitating assembly and disassembly. Furthermore, by housing the light source 11 of the main lighting module 10 within the light source cavity of the light mixing element 12, which is formed by connecting a light-emitting portion 121 and a connecting portion 122 of equal wall thickness, with both the light-emitting portion 121 and the connecting portion 122 protruding towards the side opposite to the light source cavity, the light emitted from the light source 11 can be deflected by the light-emitting portion 121 and the connecting portion 122 before being emitted, achieving 360° uniform light emission from the main lighting module 10 and a decorative effect without blind spots.

[0064] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
