[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with specific embodiments.

[0034] Embodiment 1

[0035] The cabinet lamp of this embodiment includes a bracket 2, a lamp controller 1 and a plug-in light bar 3, wherein the bracket is formed with a mounting groove and at least two wires are arranged on the inner side of the mounting groove, and the wires are arranged at intervals and extend along the mounting direction of the mounting groove, i.e., the length direction; the lamp controller 1 includes a cavity housing, such as a rectangular cavity housing 11, which can be matched and inserted into the mounting groove, a control circuit board fixedly arranged inside the cavity housing, a control switch 12 electrically connected to the control circuit board, and a controller sliding contact 13 arranged on the control circuit board and electrically connected to the drive output of the control circuit, wherein the controller sliding contact extends from the slot 16 on the cavity housing and is arranged corresponding to the wires. The plug-in light bar 3 includes a long cavity light bar housing 31 which can be matched and inserted into the mounting groove, a lamp body arranged in the light bar housing for energizing and illuminating, and a light bar sliding contact 34 which protrudes relative to the outer surface of the light bar housing and is electrically connected to the lamp body, and the light bar sliding contact is arranged corresponding to the wires to achieve respective conduction. The controller sliding contact and the light bar sliding contact are elastic electrode sheets, such as arc-shaped, or plate-shaped structures with arc-shaped ends, which are made of elastic metal and have the characteristics of conduction and elastic deformation.

[0036] The cabinet lamp, light strip and lamp controller of the present invention all adopt a plug-in structure, and after plug-in, conduction is achieved by contact between the wire and the controller sliding contact or the lamp body sliding contact, realizing a one-step operation of installation and conduction, thereby improving its disassembly and assembly, and enabling the individual sale of parts and components. It can be easily disassembled and assembled without the need for professionals, thereby improving the convenience of free assembly, reducing welding points, achieving on-demand assembly, reducing specification and model settings, and being more conducive to market expansion and meeting consumer needs.

[0037] Preferably, the lamp body is an LED lamp body, which can be a plurality of strips arranged in the housing of the light bar, each of which is connected to a corresponding sliding contact of the light bar, and is connected to the corresponding sliding contact of the controller and the output of the controller through a wire. Through different conduction and control, different colors or combinations can be achieved to improve the lighting effect. That is, to achieve the diversity of control, the wires are arranged at intervals of at least two, preferably three or more, and the controller contacts and the light bar contacts are arranged correspondingly. Multiple contacts can achieve parallel output to ensure the stability of subsequent control output. At the same time, different control outputs can also be achieved, such as driving two different groups of light bars to achieve display effects or display states of different colors.

[0038] When the bracket is made of insulating material, the wire can be directly fixed and set. If the bracket is a conductor, necessary insulation treatment is required. The wire, such as the FPCB wire, can be attached to the installation groove by double-sided adhesive or the like. It can be set in a section or along the entire length of the bracket according to the situation. The installation groove is provided with an opening corresponding to the control switch to realize its switch function when necessary.

[0039] The lamp controller 1 further includes a power supply interface 14 formed on one side of the housing and electrically connected to the control circuit board to realize external power supply. The control switch 12 is a toggle switch, a human body sensing switch or a radar sensing switch. The plug-in design of the power supply interface, the multi-category supply of the control switch, and the simple output connection facilitate subsequent replacement and on-demand assembly. The control switch can be set on the side or bottom of the cavity housing to meet different usage requirements.

[0040] Furthermore, a through groove 31 is correspondingly provided on the light bar shell, and the sliding contact of the lamp extends from the inner end of the through groove and is electrically connected to the lamp body. Wherein, the two ends of the cavity light bar shell are open, and the through groove is formed at the end of the cavity light bar shell, that is, the through groove is a U-shaped opening design. The end opening design can effectively avoid excessive extrusion of the sliding contact during substrate assembly, thereby ensuring its good design form. A plug-in end plug is provided at the opening. Preferably, the sliding contact is provided at both ends of the light bar shell. Through the symmetrical design at both ends, one or two groups of different lamp bodies can be arranged in the light bar shell. For one group of lamp bodies, both ends can be connected to avoid disability caused by sliding contact failure, and two groups of different designs can realize lamp bodies of different colors or designed brightness. Each group of sliding contacts corresponds to a lighting state, which can expand its practical scope, and is particularly suitable for use scenarios with high requirements for color change. Wherein, the cavity light bar shell is co-extruded by a material with at least a bottom having a light diffusion effect or light guiding or transparent.

[0041] Embodiment 2

[0042] On the basis of the above embodiment, specifically, in order to improve the convenience of assembly, the installation groove is a U-shaped groove, the wire is arranged on the inner top plate of the installation groove, the cavity shell is formed by buckling and welding the lower shell and the upper shell, and the slot is arranged on the top plate of the upper shell. The light bar sliding contact is correspondingly arranged on the upper top plate of the light bar shell, that is, the light bar shell is correspondingly provided with a through groove, the light bar sliding contact extends from the through groove, and the electrical conduction structure arranged on the top is in line with the usage habits.

[0043] Furthermore, the lamp body and the light bar sliding contact are both arranged on a long strip substrate (PCB board), and an inner positioning groove corresponding to the long strip substrate is arranged in the light bar housing. The inner positioning groove type light bar assembly is convenient for assembly, and the substrate type lamp body can be sold as an independent accessory. Generally, the applicable user can easily replace the lamp body, reduce the use cost, and the simple lamp body replacement reduces the replacement of the light bar housing, prolongs its service life, and effectively achieves energy saving and emission reduction.

[0044] The controller sliding contact is an arc-shaped sliding contact ring with both ends fixedly connected to the control circuit board, and the light bar sliding contact is an arc-shaped sliding contact ring with both ends fixedly connected to the control circuit board. The sliding contact ring is also made of elastic metal and can be made of the socket sleeve material. The arc-shaped sliding contact ring has stable contact connection, strong deformation recovery force, and can maintain stable plug-in and electrical connection.

[0045] Among them, the inner side surface of the installation groove is provided with a groove or ridge corresponding to the side surface of the cavity shell and the lamp body shell for guiding and positioning. A guide ridge 23 is formed on the inner side surface of the installation groove, and the left and right side surfaces of the cavity shell and the light bar cavity are provided with a controller groove 15 and a lamp body groove 33. The use of grooves or ridges for guidance can achieve insertion and positioning, reduce assembly costs, and facilitate later replacement. The lamp controller and the light bar are interference fit with the bracket, which is simple and convenient to assemble.

[0046] Embodiment 3

[0047] As a specific application of cabinet lights, the bracket can be fixed in a magnetic way, or connected by screws, bonded, or in a way that matches the cabinet. Specifically, Figure 2 and Figure 5 As shown, the bracket is formed with a connecting strip perpendicular to the side of the installation slot in its length direction. The use of the connecting strip can conveniently position the bracket in the prefabricated slot of the cabinet to achieve quick integrated installation. The bracket is a co-extruded aluminum profile, which includes a mounting slot 21. The light bar 3 and the lamp controller 1 are correspondingly embedded in the mounting slot 21. At the same time, in order to improve the overall aesthetics, the bracket also includes a closed or open wiring slot 24, which is arranged at the top or one side of the mounting slot. The wiring slot cross-section is rectangular. The wiring slot 24 is a channel-like space arranged in one of the mounting slots for laying power lines.

[0048] like Figure 6 As shown, the bracket 5 is a co-extruded aluminum profile, and wiring grooves are formed on the top and outside of the installation groove 21 respectively. The bottom surface 51 of the outer wiring groove is designed in an arc shape. The arc surface design of the wiring groove adjacent to the installation groove can improve the light output angle and illumination range.

[0049] like Figure 7 As shown, the bracket 6 is a co-extruded aluminum profile, and triangular wiring grooves are formed on the top and outside of the installation groove respectively. At the same time, a clamping wing 61 is provided on the inner side of the installation groove at an acute angle to the side of the installation groove. The elastic clamping wing 61 can be used to clamp and position it in the open groove to achieve positioning installation to meet customer usage requirements.

[0050] like Figure 8 As shown, in order to improve the lighting effect, multiple devices, such as two installation slots 21, can be provided on the bracket 7, two groups of controllers 1 and light strips 3 can be provided on one bracket, or two groups of light strips in different installation slots can share one controller, thus realizing multi-directional and multi-form lighting, greatly expanding the needs of different users.

[0051] The lamp of the present invention realizes quick installation and positioning by using the connection strip and the cabinet fixing groove. At the same time, positioning edges are formed on the upper and lower parts of the connection strip to ensure effective transition between the bracket and the cabinet, etc., and realize visual seamless connection effect while ensuring the connection. At the same time, the wiring groove formed on one side further ensures the overall aesthetic effect.

[0052] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "on" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0053] The present invention is described above by way of example. It should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacement that can be made by those skilled in the art without inventive effort falls within the protection scope of the present invention.
