DETAILED DESCRIPTION

[0031] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] A preferred embodiment of the light emitting module of the present invention is shown in FIG. Figures 1 to 3 As shown, the light emitting module 100 includes: a hollow connecting rod 1, a light guide 2, a first end 3, a second end 4 and a light source module 5. The hollow connecting rod 1 is a connecting rod with two ends connected. The hollow connecting rod 1 is preferably a round tube, but is not limited to a round tube, and can also be a polygonal structure. The light guide 2 is made of a transparent or translucent material, such as acrylic. The light guide 2 is a round tube or a polygonal tube. In this embodiment, the light guide 2 is a round structure. The inner diameter of the light guide 2 is greater than the maximum diameter of the hollow connecting rod 1, and the light guide 2 is sleeved on the outside of the hollow connecting rod 1. The first end 3 and the second end 4 are respectively connected to the two ends of the hollow connecting rod 1, so that the light guide 2 is clamped between the first end 3 and the second end 4. The light source module 5 is arranged at one end of the light guide 2 and is located between the first end 3 and the hollow connecting rod 1, so that the light emitted by the light source module 5 is emitted from the end of the light guide 2. In other embodiments, the light source module 5 can also be arranged between the second end 4 and the hollow connecting rod 1. In this embodiment, a connecting plug 31 extending outward from the surface of the first end 3 is provided on a side away from the hollow connecting rod 1, and a first joint 32 is provided in the connecting plug 31. A connecting hole seat 41 extending outward from the surface of the second end 4 and inserted into the hollow connecting rod 1 is provided on a side close to the hollow connecting rod 1. The connecting hole seat 41 is provided with a connecting through hole 411 matching the connecting plug 31, and a second joint 42 matching the first joint 32 is provided in the connecting through hole 411. The first joint 32 is electrically connected to the light source module 5 and the second joint 42 respectively through a wire, and the light source module 5 is arranged in parallel with the second joint 42. The first joint 32 is electrically connected to the second joint 42 and the light-emitting module 5 respectively through a wire (not shown in the figure), and the wire extends from one end to the other end along the middle cavity of the hollow connecting rod 1, and connects the first joint 41 and the second joint 42 respectively.

[0033] When using, Figure 6 As shown, the connecting plug 31 of the first end portion 3 of a light-emitting module 100 is inserted into the module base 210 provided on the lamp holder 200, and the first connector 32 of the light-emitting module 100 is electrically connected with the second connector (not shown) in the module base 210 on the lamp holder 100. A wire is provided inside the lamp holder 200 to connect the second connector in the module base 210 with an external power supply, and the external power supply supplies power to the light source module 100 through the second connector and the first connector 32 in sequence. When the switch is turned on, the light source module 5 is connected to the external power supply, the light source on the light source module 5 emits light, and the light is emitted into the light guide tube 2 from the end of the light guide tube 2, and then emitted into the air from the side wall of the light guide tube 2. Figure 4 ,5 As shown in FIG. 6 , a structural diagram of two sections of light-emitting modules connected is shown. For example, the right side of the figure is the first section of the light-emitting module 100, and the left side is the second section of the light-emitting module 100. The connecting plug 31 of the first end 3 of the second section of the light-emitting module 100 is inserted into the connecting hole seat 41 of the first section of the light-emitting module 100. The second connector 42 of the first section of the light-emitting module 100 is electrically connected to the first connector 32 of the second section of the light-emitting module 100. The second connector 42 and the light-emitting module 5 in the first section of the light-emitting module 100 are electrically connected to the first connector 32 in the first section of the light-emitting module 100 through a wire, respectively. The light source module 5 of the second section of the light-emitting module 100 is arranged in parallel with the light source module 5 of the first section of the light-emitting module 100, and the first section and the second section of the light-emitting module 100 are both lit. The light-emitting module of the present invention has a simple structure and is easy to install. When the two sections of the light-emitting modules are connected, they can be quickly installed to realize the rapid selection of the lamp power. The light source modules between the light-emitting modules are connected in parallel to realize multi-level connection.

[0034] In order to achieve the connection and fixation of two adjacent light-emitting components, a buckle component or a threaded component can be provided between the connecting plug 31 and the connecting hole seat 41 to achieve the connection. Figure 2 As shown, the outer surface of the connecting plug 31 is provided with a connecting external thread 311 , and the connecting through hole 411 is provided with a connecting internal thread 413 . The connecting plug 31 and the connecting seat hole 41 are matingly connected through the connecting external thread 311 and the connecting internal thread 413 .

[0035] The light source module 5 includes a circuit board 51, a driving component 52 and a light source 53. The driving component 52 and the light source 53 are respectively arranged on the circuit board 51, and the driving component 52 and the light source 53 are electrically connected through a circuit arranged on the circuit board 51. The light source 53 is annularly arranged on the circuit board 51 in a manner corresponding to the light guide 2. In other embodiments, the driving component 52 can also be arranged in a lamp holder. The light source module 5 also includes a main control circuit (not shown in the figure), which is connected to the driving component 52 and is used to control the light source 53 to emit light. Each light-emitting module 100 is provided with a main control circuit to control the driving component 52 to control the light emission of the light source, so as to adjust the light color and light brightness of a single light-emitting module.

[0036] In this embodiment, Figure 2 and 3As shown, the light source module 5 is arranged between the first end 3 and the hollow connecting rod 1, and the light emitting module also includes a base 6, the light source module 5 is installed on one side of the base 6, and the first end 3 is installed on the other side of the base 6, and the first end 3, the base 6, the light source module 5 and the hollow connecting rod 1 are connected by screws. The base 6 is provided with a decorative ring 61, which is connected to the edge of the base 6 and extends from the edge to the direction perpendicular to the two surfaces of the base 6 to form a receiving groove for respectively accommodating the light source module 5 and the first end 3, that is, a light source receiving groove for accommodating the light source module and a connector receiving groove for accommodating the first end are formed, and the two receiving grooves allow the light source module and the first end to be embedded therein, and the first end 3 and the light source module 5 are hidden in the receiving grooves, so that the aesthetics of the light emitting module is improved.

[0037] The hollow connecting rod 1 is detachably connected to the first end portion 3 and the second end portion 4. The hollow connecting rod 1 and at least one of the first end portion 3 and the second end portion 4 adopt a detachable connection structure. Figure 2 As shown, in this embodiment, the connection hole seat 41 is provided with a first fixing thread 412, and the end of the hollow connecting rod 1 close to the second end 4 is provided with a second fixing thread 11, and the hollow connecting rod 1 and the second end 4 are connected through the first fixing thread 412 and the second fixing thread 11. The end of the hollow connecting rod 1 close to the first end 3 is provided with a screw hole (not shown in the figure), and the hollow connecting rod 1 and the first end 3 are connected through the screw and the screw hole. In this embodiment, the first fixing thread 412 is an external thread, and the second fixing thread 11 is an internal thread, which cooperate with each other to form a connection. It should be noted that the first fixing thread 412 can be an internal thread, and the corresponding second fixing thread 11 can be an external thread.

[0038] Further, such as Figure 2 and 3 As shown, a sealing gasket 7 is provided between the second end portion 4 and the hollow connecting rod 1. The sealing gasket 7 can not only seal the second end portion 4 and the hollow connecting rod 1 and the light guide tube 2, but also play a buffering role.

[0039] Further, such as Figure 2 and 3 As shown, the light-emitting module further includes a glass cover 8, which is arranged on the outside of the light guide 2 to prevent the surface of the light guide 2 from being worn, and to play a role in light uniformity and light distribution compensation. Generally, the light guide 2 is made of acrylic material, and the surface is easily scratched and worn, which not only makes the lamp unsightly, but also affects the emission of light. The hardness of the glass cover is greater than that of the light guide, and the surface is not easy to wear, thereby ensuring the emission effect of light.

[0040] Further, the light-emitting module also includes a reflective component 9, which is arranged at the end of the light guide 2 and is used to concentrate the light emitted by the light source 53 into the light guide 2. The reflective component 9 includes an outer annular wall 91, an inner annular wall 92 and a bottom wall 93 arranged in parallel, the inner annular wall 92 and the outer annular wall 91 are arranged at intervals, and the bottom wall 93 connects the inner annular wall 92 and the outer annular wall 91 to form a reflective cavity (not shown in the figure), and the bottom wall 93 is provided with a light source through hole 94, the end of the light guide 2 is embedded in the light guide cavity, the bottom wall 94 is attached to the end face of the light guide 2, and the light source 53 is arranged corresponding to the light source through hole 94. The end of the light guide 2 is embedded in the light guide cavity, and the light emitted by the light source 53 enters the light guide cavity through the light source through hole 94, enters the end of the light guide 2, and is partially reflected by the reflective component 9, which can make the light better concentrated and enter the light guide 2, improve the light efficiency, avoid the waste of stray light, and form a uniform light emission.

[0041] In order to make the light guide tube 2 better guide light, light guide particles are added inside the light guide tube 2, and the light guide particles are selected according to the light guide requirements. In addition, the outer surface of the light guide tube 2 can be sun-textured or etched to guide the light that is totally reflected inside to scatter and emit from the outer surface.

[0042] It should be noted that in other embodiments, the light source module 5 can also be arranged between the second end 4 and the hollow connecting rod 1. Since the second end 4 is provided with a connecting hole seat 41, if the light source module 5 is arranged between the second end 4 and the hollow connecting rod 1, the circuit board 51 should be arranged in a ring shape, and the setting position of the driving component 52 will be difficult, and it will also be difficult to achieve electrical connection between the connecting plug 31 and the light source module 5. Therefore, compared with the above-mentioned embodiments, this embodiment is not a better embodiment. In addition, the light-emitting module 100 can also simultaneously set the light source module 5 at both ends of the light guide 2, and inject light from both ends of the light guide 2. This embodiment is only to add a light source module 5 on the basis of the technical content of the present invention, so it falls within the protection scope of the present invention.

[0043] The light emitting module 100 can also be used as a light source alone. Figure 7 As shown, the light emitting module 100 is used as a light source. Figure 6 As shown, the light emitting module 100 can be connected in multiple sections.

[0044] The present invention also discloses a lamp, such as Figures 7 to 8 As shown, a preferred embodiment of the lamp of the present invention is shown, the lamp comprises a base 400, a lamp connecting rod 300 extending from the base 400, a lamp holder 200 formed at the end of the lamp connecting rod 300, and a module base 210 extending from the peripheral side of the lamp holder 200, each module base 210 is connected to a light-emitting module 100 described in the above embodiment, and the base 400, the lamp connecting rod 300 and the lamp holder 200 are all hollow structures. Figure 8 As shown, the lamp holder 200 is provided with a hollow threaded joint 230, and the lamp connecting rod 300 is connected to the hollow threaded joint 230. The power supply wire (not shown in the figure) passes through the hollow lamp connecting rod 300 and the lamp holder 200 from the base 400 and is electrically connected to the module base 210 for supplying power to the light-emitting module 100. A plurality of module bases 210 are arranged in parallel. The connecting plug 31 of the light-emitting module 100 is cooperatively connected with the module base 210. The structural principle of the module base 210 is the same as the structural principle of the connecting hole seat 41 of the light source module 100 of the aforementioned embodiment. There is only a difference in appearance, which can be understood by those skilled in the art and will not be repeated here. The lamp holder 200 is preferably a polygon. In the present embodiment, the lamp holder 200 is a quadrilateral, and the module base 210 extends from the vertex 220 of the lamp holder 200. A plurality of module bases 210 are arranged at each vertex 220, such as Figure 8 As shown, each vertex 220 is provided with three module bases 210, and the three module bases are distributed in different directions to form a better three-dimensional light emission. In this embodiment, the base 400 is used to be installed on the ceiling. The base 400 is not limited to being installed on the ceiling, but can also be installed on other buildings. Figure 6 As shown, the lamp frame 200 is provided with 12 module bases 210, each module base 210 is connected to two sections of light-emitting modules 100, and the lamp is installed with a total of 24 sections of light-emitting modules 100, forming a three-dimensional light-emitting structure with beautiful shape and uniform brightness.

[0045] It should be noted that the embodiments of the present invention have better practicability and do not impose any form of limitation on the present invention. Any technician familiar with the field may use the technical content disclosed above to change or modify it into an equivalent effective embodiment. However, any modification or equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
