Description

Technical Field

[0001] The utility model belongs to the technical field of lamps, and particularly relates to a spliced lamp housing. Background Art

[0002] In the field of lighting technology, as an important device for providing light, the structural design and manufacturing cost of a lamp are directly related to the market competitiveness of the product. In traditional lamp designs, the lamp housing, as a key component for supporting and protecting the internal light source components and electrical components, usually adopts an integrated design, in which a light source cavity and an electrical cavity are respectively arranged along the head end to the tail end direction of the lamp housing. The light source cavity is mainly used for installing optical components such as a PCB board and a lens to realize the generation and regulation of light; while the electrical cavity is used to accommodate electrical components such as a power supply and a control circuit, which are responsible for the conversion and control of electrical energy.

[0003] However, with the increasing diversification of the lighting market and the diversification of user needs, the limitations of this fixed-structure lamp housing gradually emerge. Specifically, different users and application scenarios have different requirements for the brightness, light distribution of the light source, and electrical configuration, which often requires adjusting the size and layout of the light source cavity or the electrical cavity. For example, high-brightness lighting requirements may need a larger light source cavity to accommodate a higher-power LED array, while some special installation environments may require the electrical cavity to have a higher level of waterproof and dustproof or additional heat dissipation design.

[0004] In the face of these changes, the traditional approach is usually to redesign and mold a new lamp housing for each new requirement, which not only leads to an extended R & D cycle but also significantly increases the manufacturing cost, and is not conducive to the rapid iteration of products and market response. In addition, a large number of customized molds also increase the difficulty of inventory management and maintenance, further increasing the operating cost of the enterprise.
