[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] See Figures 1 to 3 As shown, a novel snap-on wardrobe cabinet light structure includes a heat sink 1, a lamp housing 2, and a light source plate 3. The lamp housing has a recessed cavity 4 with an opening on the top surface, and an illumination channel 5 communicating with the recessed cavity is provided on the bottom wall of the lamp housing. The lamp housing is a plastic structural component. In this embodiment, the heat sink is a conventional structure of the prior art, simply applied. The width and length of the illumination channel are smaller than the length and width of the recessed cavity, and the light source plate is also a conventional structure of the prior art, therefore not described in detail.

[0026] In this embodiment, the light source board includes a substrate 31, two parallel conductive contact pieces 32 arranged on the top surface of the substrate, and a plurality of lamp beads 33 welded and fixed on the bottom surface of the substrate, with the lamp beads connected in parallel between the two conductive contact pieces; the light source board is located in a concave cavity and fixed to the top surface of the bottom wall of the concave cavity by screws; in actual application, the lamp beads are connected in parallel, which can improve the stability of use.

[0027] Furthermore, the top surface of the heat sink is fixed with a conductive terminal 6 for connecting to a low-voltage power supply, and the bottom surface of the heat sink is fixed with a positive contact 7 and a negative contact 8 connected to the conductive terminal. A snap-fit ​​groove 9 is provided on the symmetrical inner wall of the cavity, and a snap-fit ​​protrusion 10 is integrally formed on the edge of the heat sink. During assembly, the heat sink is placed inside the cavity, the snap-fit ​​protrusion is engaged in the snap-fit ​​groove, and the positive and negative contacts are electrically connected by abutting against the two conductive contacts. In use, when the heat sink is inserted into the lamp housing, it will slightly deform the lamp housing under external force. After the snap-fit ​​protrusion is engaged in the snap-fit ​​groove, the lamp housing returns to its original position, thus ensuring the stability and reliability of the connection between the lamp housing and the heat sink. It also ensures that the positive and negative contacts abut against the conductive contacts, guaranteeing effective power supply.

[0028] In this embodiment, a lens panel 11 is provided at the illumination channel; the light from the light source plate is emitted outward through the lens panel. The lens panel is an acrylic material structure or a glass structure. During installation, the edge of the lens panel is attached to the top surface of the bottom wall of the cavity, and is positioned by clamping the light source plate with the bottom wall of the cavity.

[0029] In this embodiment, an insulating layer 12 is provided at the connection between the positive electrode contact and the heat sink, and at the connection between the negative electrode contact and the heat sink. This can improve the insulation layer at the connection between the heat sink and the positive electrode contact, and between the heat sink and the negative electrode contact.

[0030] In practical applications, the shape of the heat sink matches the shape of the cavity, and the size of the heat sink matches the size of the cavity. The positive electrode contact, negative electrode contact, and conductive contact are all copper components.

[0031] An isolation layer 13 is provided between the edge of the substrate and the inner wall of the cavity. The isolation layer can improve the sealing between the substrate and the inner wall of the cavity, which helps to prevent light leakage.

[0032] This utility model has positive effects: The structure of this utility model is reasonable. It has conductive terminals on the heat sink plate, which are equipped with positive and negative contacts and conductive contacts on the top surface of the substrate. During assembly, the positive and negative contacts are electrically connected by abutting against the two conductive contacts, which improves the convenience of connection and the effectiveness of power supply. It also helps to reduce the overall size of the lamp, which helps to meet the needs of different situations. It is stable and reliable in use and has strong applicability.

[0033] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0034] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
