DETAILED DESCRIPTION OF THE EMBODIMENTS

[0063] The present disclosure will be described in detail hereinafter with reference to the drawings.

Embodiment 1

[0064] A preferred embodiment of a bracket for a modular luminaire of the present disclosure is shown in FIGS. 1-9, 11 and 12.

[0065] The specific technical solution of the bracket for modular luminaires of the present embodiment is as follows:

[0066] The bracket 1 for modular luminaires includes the polyhedral module 100 and the connector 200 connected to the polyhedral module 100. The polyhedral module 100 is detachably connected to the connector 200 by a snap-fit connection structure. The plurality of polyhedral modules 100 are interconnected by the connectors 200 as needed to form the bracket for modular luminaires.

[0067] In the present disclosure, the polyhedral module 100 may be an irregular tetrahedron, an irregular hexahedron, an irregular octahedron, etc., or may be a regular tetrahedron, a cuboid, a regular hexahedron, or a regular octahedron, etc.

[0068] The present embodiment will be described in detail below with an example showing that the polyhedral module 100 is a regular hexahedron.

[0069] As shown in FIG. 3, the polyhedral module 100 is a regular hexahedron provided with the cavity 110 therein, and each surface of the hexahedron is provided with the stepped through-hole 120 connected to the cavity 110, thereby forming the first annular protrusion 130 at a junction of the stepped through-hole 120 and the cavity 110. Preferably, the polyhedral module 100 is made of plastic.

[0070] Further, the first through-hole 140 connected to the cavity 110 is provided on each surface of the polyhedral module 100; and two of the first through-holes 140 located on opposite surfaces of the polyhedral module 100 correspond to each other.

[0071] Because the stepped through-hole 120 and first through-hole 140 intercommunicate and are provided on the polyhedral module 100, and the connector body 211 is provided with the through-hole 211 along the axial direction, the reinforcing strip 400 can be inserted into the plurality of the interconnected polyhedral module 100 for reinforcing, fixing and supporting the bracket for modular luminaires; or a wire can be inserted into the plurality of interconnected polyhedral modules 100 for forming an electrical connection in the bracket for modular luminaires.

[0072] The connector 200 may be made of a soft resin material or a hard resin material, which also has different lengths and types.

[0073] As shown in FIG. 4, the connector 200 includes the connector body 210 having a cylindrical shape; and the connector body 210 is provided with the through-hole 211 along an axial direction. On an outer periphery of the connector body 210, the second annular protrusion 212, the third annular protrusion 213, the fourth annular protrusion 214, and the fifth annular protrusion 215 protrude outwards in a radial direction and are formed successively from a left end portion to a right end portion of the connector body 210.

[0074] The second annular protrusion 212, the third annular protrusion 213, the fourth annular protrusion 214 and the fifth annular protrusion 215 are spaced apart.

[0075] As shown in FIGS. 6, 7 and 8, a left end of the connector 200 is inserted into the stepped through-hole 120 of the polyhedral module 100, and the first annular protrusion 130 is engaged between the second annular protrusion 212 and the third annular protrusion 213, so that the connector 200 is detachably connected to the polyhedral module 100.

[0076] Any two polyhedral modules 100 are connected by the connector 200, and a plurality of the polyhedron modules 100 are connected in series to form a strip structure. The plurality of strip structures can also be interconnected through the corresponding stepped through-holes 120 on the polyhedral module 100 and the connector 200, so that the plurality of polyhedral modules 100 are interconnected via the connector 200 as needed, thereby forming the bracket for modular luminaires as shown in the FIGS. 1 and 2.

[0077] In the prior art, the luminaire bracket is usually made in the manner of molding and handcrafting, but the molding is expensive and the handcrafting is inefficient. Therefore, the bracket for LED luminaires has poor adaptability, and usually only one bracket corresponds to one luminaire, which causes a poor commonality. In order to solve this technical problem, the present disclosure provides a structural design of a bracket for modular luminaires based on long-term research. The polyhedral modules can be arbitrarily connected in a plug-in manner, bent, discolored, and fixed. Then wires can be connected inside the polyhedron module to form a low-cost, structurally common, simple, variable-shaped frame/bracket structure for luminaires.

[0078] Specifically, by the arrangement of the stepped through-hole 120 and the first annular protrusion 130 on the polyhedral module, and the arrangement of the second annular protrusion 212, the third annular protrusion 213, the fourth annular protrusion 214 and the fifth annular protrusion 215 on the connector 200. The polyhedral module and the connector 200 is connected together in an snap-fit manner that can easily be detached; and a plurality of the polyhedral modules 100 are interconnected via the connector 200 as needed to form the bracket for modular luminaires, thereby solving the problem of “one bracket only corresponds to one luminaire” in the prior art.

[0079] Preferably, a portion between the third annular protrusion 213 and the fourth annular protrusion 214 of the connector body 210 is wavy, zigzag, or threaded, so that the portion between the third annular protrusion 213 and the fourth annular protrusion 214 of the connector body 210 forms a retractable structure, as shown in FIG. 5.

[0080] By the arrangement of a retractable structure in the middle position of the connector body 210, a connection portion between two polyhedral modules 100 can be bent to change or adjust the connection angle.

[0081] Further, in the present embodiment, the cover sheet 300 is included. As shown in FIG. 9, the cover sheet 300 includes the sheet body 310 and the snap-fit portion 320 connected to the sheet body 310.

[0082] The sheet body 310 is a decorative sheet having a size matching the surface of the polyhedral module 100 on an outer surface of the bracket for modular luminaires. The snap-fit portion 320 includes the first cylindrical platform 321 provided on the sheet body 310 and the second cylindrical platform 322 coaxially provided on the first cylindrical platform 321. Moreover, a diameter of the second cylindrical platform 322 is smaller than that of the first cylindrical platform 321, so the snap-fit portion 320 forms into a stepped platform matching the stepped through-hole 120.

[0083] Through the matching of the snap-fit portion 320 with the stepped through-hole 120, the cover sheet 300 is connected to the polyhedral module 100 to form an interference fit, as shown in FIG. 11.

[0084] A decorative surface of the cover sheet 300 can be provided with different colors, textures or patterns to play the role of decorating the luminaire. Moreover, the cover sheet 300 and the polyhedral module 100 are detachably connected by the interference fit, which can be conveniently replaced at any time, thereby satisfying the preferences of different groups of people.

[0085] Further, as shown in FIG. 12, the second through-hole 330 is provided on the cover sheet 300. The cover sheet provided with the second through-hole 330 is installed at a position where a power supply port is mounted on the bracket for modular luminaires, so that the power supply port is exposed to facilitate the plugging in of the power supply.

[0086] Further, in the present embodiment, the reinforcing strip 400 is included. The reinforcing strip 400 is preferably a metal strip or hard plastic strip.

[0087] As shown in FIG. 14, the reinforcing strip passes through the stepped through-hole 120 of the plurality of polyhedral modules 100 and the through-hole 211 in the connector body 210, or passes through the first through-hole 140, which is used for reinforcing, fixing and supporting the bracket for modular luminaires. Consequently, the bracket for modular luminaires form an overall structure with a strong bearing capacity.

[0088] Further, in the present embodiment, the wire 500 is included. The wire 500 passes through the stepped through-hole 120 of the plurality of polyhedral modules 100 and the through-hole 211 in the connector body 210, or passes through the first through-holes 140 forming an electrical connection in the bracket for modular luminaires.

[0089] The brackets for modular luminaires shown in FIG. 1 and FIG. 2 of the present disclosure are merely exemplary, and beyond that, they may be connected and combined to form into different shapes according to actual needs.

Embodiment 2

[0090] The main difference between the present embodiment and Embodiment 1 is that the structure of the cover sheet 300 is different.

[0091] As shown in FIG. 10, the cover sheet 300 includes the sheet body 310 and the snap-fit portion 320 connected to the sheet body 310.

[0092] The sheet body is a decorative sheet having a size matching the surface of the polyhedral module 100 on an outer surface of the bracket for modular luminaires.

[0093] The snap-fit portion 320 includes the cylinder 323 provided on the sheet body 310, and the sixth annular protrusion 324 and the seventh annular protrusion 325 are formed radially outward on an outer periphery of the cylinder 323. The sixth annular protrusion 324 is spaced apart from the seventh annular protrusion 325.

[0094] The snap-fit portion 320 is inserted into the stepped through-hole 120 on the polyhedral module 100, and the first annular protrusion 130 is engaged between the sixth annular protrusion 324 and the seventh annular protrusion 325, making the cover sheet 300 connect to the polyhedral module 100 in a snap-fit manner.

[0095] The other structures in the present embodiment are the same as those in Embodiment 1.

Embodiment 3

[0096] The present embodiment discloses the modular luminaire 2. The specific technical solution is as follows:

[0097] As shown in FIG. 13, the modular luminaire 2 includes the bracket 1 for modular luminaires as described in Embodiment 1 or 2 and the light source module 600 mounted on bracket 1 for modular luminaires.

[0098] The power supply port 700 and the control switch 800 are provided on the bracket 1 for modular luminaires. The power supply port 700 and the control switch 800 are interconnected via a wire. The control switch 800 and the light source module 600 are also interconnected via a wire.

[0099] According to the modular luminaire of the present embodiment, the bracket for modular luminaires is provided with the stepped through-hole and the first annular protrusion on the polyhedral module, and with the second annular protrusion, the third annular protrusion, the fourth annular protrusion and the fifth annular protrusion on the connector. Consequently, the polyhedral module and the connector can be detachably connected together in an snap-fit manner; and a plurality of the polyhedral modules are interconnected via the connectors as needed to form the bracket for modular luminaires, thereby solving the problem of “one bracket only corresponds to one luminaire” in the prior art.

[0100] It should be noted that all features disclosed in the specification, or the steps of all methods or processes disclosed, may be combined in any manner other than mutually exclusive features and/or steps.

[0101] In addition, the above-mentioned specific embodiments are exemplary, and a person skilled in the art can be inspired by the disclosure of the present disclosure to devise various solutions, and these solutions also belong to the disclosed scope of the present disclosure and fall within the protective scope of the present disclosure. It should be understood by a person skilled in the art that the specification and the drawings of the present disclosure are illustrative rather than forming a limitation on claims. The protective scope of the present disclosure is defined by the claims and their equivalents.
