[0031] The present application discloses a structure of a projection lamp, which is mainly used to solve the problem that the end of the heat dissipation body of the existing projection lamp with a sunflower structure is easy to scratch the staff.

[0032] Referring to Figure 1 , 2 , the structure of the projection lamp comprises a light-emitting module 1, a power module 2 and a heat dissipation module 3. The heat dissipation module 3 comprises a lamp housing 4 and a plurality of heat dissipation fins 5 fixed circumferentially on the lamp housing 4. The lamp housing 4 is provided with a light source cavity for mounting the light-emitting module 1. When the light-emitting module 1 is mounted, it is embedded in the light source cavity and fixedly connected with the lamp housing 4 through bolts and other fixing members, so as to ensure that the light-emitting module 1 is stable and not loose during work.

[0033] Referring to Figure 2 , 3A protective cover 6 is mounted on the outer periphery of the heat dissipation fins 5, which is annular, the inner diameter is matched with the distribution of the outer periphery of the heat dissipation fins 5, and the end of the heat dissipation fins 5 is entirely covered. The protective cover 6 can be made of engineering plastic material with certain strength and toughness, which can not only ensure the protection of the end of the heat dissipation fins 5, but also will not significantly affect the heat dissipation effect.

[0034] Referring to Figure 4 , 5 The protective cover 6 is composed of a plurality of spliced segments 7, each spliced segment 7 is arc-shaped, and the inner side of both ends of the spliced segment 7 is fixed with a clasp 8. Correspondingly, the outer side of the lamp shell 4 is fixedly connected with a connecting fin 9, and the end of the connecting fin 9 away from the lamp shell 4 is provided with a clamping groove 10 for clamping and fixing the clasp 8. When installing the protective cover 6, the clasp 8 of the spliced segment 7 is inserted into and clamped in the clamping groove 10, and the installation of the protective cover 6 is completed. In addition, the number of clamping grooves 10 of each connecting fin 9 is two, so that one end of the adjacent two spliced segments 7 can be clamped on one connecting fin 9, thereby saving space.

[0035] A reinforcing rib 11 is fixed between the clasp 8 and the spliced segment 7, the reinforcing rib 11 is made of the same material as the spliced segment 7, and is connected with the spliced segment 7 and the clasp 8 by injection molding. The setting of the reinforcing rib 11 effectively enhances the structural strength of the clasp 8, so that it can withstand greater tension and pressure during installation and use, and avoid the situation that the protective cover 6 is not firmly installed due to the breakage or deformation of the clasp 8.

[0036] Referring to Figure 4 , 5 A plurality of heat dissipation holes 12 are arranged on the protective cover 6 at equal intervals, the heat dissipation holes 12 are long strip-shaped, the arrangement direction is perpendicular to the extension direction of the heat dissipation fins 5, and the positions of the heat dissipation holes 12 and the heat dissipation fins 5 are staggered. In this way, the effective protection of the end of the heat dissipation fins 5 by the protective cover 6 is ensured, and the uniform flow of air inside the protective cover 6 is ensured, and the heat dissipation efficiency of the heat dissipation module 3 is further improved through the cooperation between the heat dissipation holes 12 and the heat dissipation fins 5.

[0037] Referring to Figure 6 The light projecting lamp structure further includes a connecting bracket 13, one end of the connecting bracket 13 is fixedly connected with the heat dissipation module 3, the power module 2 is fixed on the connecting bracket 13, and the heat dissipation module 3 and the power module 2 are spaced apart by the connecting bracket 13 to form a heat dissipation space. The heat generated by the power module 2 during operation can be quickly dissipated through the heat dissipation space, avoiding the accumulation of heat to cause overheating and damage of the power module 2, thereby improving the stability and service life of the power module 2. The connecting bracket 13 is made of aluminum alloy material, which has good thermal conductivity and structural strength, and can withstand a certain weight and external impact force.

[0038] Specifically, referring to Figure 6 , the connecting support 13 comprises a mounting seat 14 and a connecting sheet 15, one end of the connecting sheet 15 is fixed on the heat dissipation fin 5 through a bolt, and the power module 2 is fixed on the mounting seat 14.

A stepped groove 16 is arranged at the notch of the light source cavity, when the light emitting module 1 is embedded in the light source cavity, the edge of the light emitting module 1 is tightly combined with the stepped groove 16, and an annular sealing groove is formed between the two.

[0040] When the panel 17 is fixed on the lamp shell 4 through a bolt, the sealing ring 19 is pressed in the sealing groove, thereby fixing the light emitting module 1 in the light source cavity, and realizing the sealing of the light source cavity. This sealing structure can effectively prevent foreign matters such as dust and water vapor from the outside into the light source cavity, and cause damage to the light emitting module 1, thereby improving the service life and reliability of the projection lamp. The middle part of the panel 17 is provided with a mounting hole for mounting the lens 18, the lens 18 passes through the mounting hole, and the edge of one end of the lens 18 abuts against the inner wall of the panel 17, and is limited and locked in the position of the light emitting module 1 through the fixation of the panel 17. The lens 18 is made of high light transmittance optical material, which ensures the efficient transmission of light and guarantees the light emitting effect and optical performance of the projection lamp.
