Detailed Implementation

[0023] like Figures 1 to 9 As shown, a projection lamp housing includes a light source box 10, which comprises a mounting bracket 11, a light source cover 12, and a light source module 13. The light source module 13 is mounted on the inner surface of the mounting bracket 11. The light source cover 12 is detachably snapped onto the mounting bracket 11. A first waterproof plug 14 is snapped onto one end of the mounting bracket 11, and a second waterproof plug 15 is snapped onto the other end, thus assembling the light source box 10. In use, the light source module 13 is powered on and emits light, which is evenly diffused through the light source cover 12 and projected onto an external target area, achieving a projection lighting effect. The first waterproof plug 14 and the second waterproof plug 15 respectively seal both ends of the mounting bracket 11, preventing external moisture and dust from entering the interior of the light source box 10, improving overall protection performance and extending the service life of the light source module 13. The detachable snap-on structure of the light source cover 12 facilitates daily maintenance, cover replacement, or cleaning of internal components, improving ease of use and maintainability. The entire light source box has a compact structure and is easy to install, making it suitable for projection lamp applications in various indoor and outdoor environments.

[0024] In practical implementation, this utility model also includes a projection lamp housing 20, which serves as the external support structure for the entire device, used to install and fix the light source box 10. The outer side of the projection lamp housing 20 is provided with several mounting slots 21. Symmetrically recessed inner sides of each mounting slot 21 are provided with mating grooves 211, and symmetrically protruding outer sides of the mounting bracket 11 are provided with mating strips 111. Two mating strips 111 correspond to two mating grooves 211. During installation, the light source box 10 can be slidably inserted along the mounting slot 21, allowing the mating strips 111 to slide into their corresponding mating grooves 211, thereby achieving a detachable sliding connection between the light source box 10 and the projection lamp housing 20. This sliding connection structure not only simplifies the assembly and disassembly process of the light source box 10 but also facilitates subsequent maintenance, cleaning, and replacement of the light source module or lampshade components, improving ease of use and overall modularity. In use, the light source box 10 is securely fixed to the side of the projection lamp housing 20. The light emitted by the light source module 13 is diffused by the light source lampshade 12, projecting a clear and uniform lighting or pattern effect. The projection lamp is suitable for various applications such as outdoor advertising, night scene lighting, and scene atmosphere creation.

[0025] In practical implementation, the mounting bracket 11 has symmetrically protruding fixing strips 112 on its upper inner side, and the light source cover 12 has symmetrically provided fixing buckles 121 on its lower sides. The fixing buckles 121 correspond to the fixing strips 112. During installation, the light source cover 12 is embedded in the upper inner part of the mounting bracket 11, and the fixing buckles 121 and the fixing strips 112 are correspondingly fastened and fixed, so that the light source cover 12 can be detachably fastened to the mounting bracket 11. During use, the fastening structure ensures that the light source cover 12 is not easy to fall off. At the same time, when it is necessary to replace the cover or clean the light source module, only appropriate external force needs to be applied to release the fastening, and it can be easily disassembled, which improves the maintainability and ease of use of the overall structure.

[0026] In practical implementation, the upper end of the first waterproof plug 14 is provided with a first positioning buckle 141, the upper end of the second waterproof plug 15 is provided with a second positioning buckle 151, one end of the light source lampshade 12 is provided with a first positioning protrusion 122, and the other end of the light source lampshade 12 is provided with a second positioning protrusion 123. When the light source lampshade 12 is embedded in the mounting bracket 11, the first positioning protrusion 122 is positioned and connected in the first positioning buckle 141, and the second positioning protrusion 123 is positioned and connected in the second positioning buckle 151, thereby realizing the double-end positioning connection of the light source lampshade 12 in the length direction. This positioning structure can effectively limit the axial movement of the light source lampshade 12, prevent loosening or displacement caused by vibration or gravity during use, and further improve the stability and safety of the installation of the light source lampshade 12.

[0027] In specific implementation, the lower end of the first waterproof plug 14 is provided with a first module protrusion 142, and the lower end of the second waterproof plug 15 is provided with a second module protrusion 152. The first module protrusion 142 and the second module protrusion 152 are respectively abutted against the two ends of the light source module 13, which not only plays a limiting and positioning role to prevent the light source module 13 from sliding axially within the mounting bracket 11, but also improves the seismic stability of the overall structure and ensures that the light source module 13 does not shift or loosen during long-term operation.

[0028] In practical implementation, the bottom of the first waterproof plug 14 is recessed with a wire through hole 143, through which the power cord of the light source module 13 extends to the outside of the light source box 10 so as to connect with the external power supply system.

[0029] In summary, the light source module 13 is mounted on the inner surface of the mounting bracket 11, the light source cover 12 is detachably snapped onto the mounting bracket 11, one end of the mounting bracket 11 is snapped with a first waterproof plug 14, and the other end of the mounting bracket 11 is snapped with a second waterproof plug 15, thereby assembling the light source box 10. The outer side of the projection lamp housing 20 is provided with several mounting slots 21, and the inner sides of the mounting slots 21 are symmetrically recessed with docking grooves 211. The outer sides of the mounting bracket 11 are symmetrically protruded with docking strips 111. The light source box 10 slides into the mounting slots 21, so that the docking strips 111 slide into the corresponding docking grooves 211, thereby realizing the detachable sliding connection between the light source box 10 and the projection lamp housing 20. The structural design of the projection lamp housing of this utility model makes the light source box easy to install and disassemble quickly, improves the modularity of the overall assembly and maintenance efficiency, and is especially suitable for indoor and outdoor projection lamp application scenarios that require frequent replacement or cleaning of light source components.
