[0027] The embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. Figures 1-3 The waterproof heat dissipation light source provided by the embodiments of the present application will be described in detail through specific embodiments and application scenarios.

[0028] Please refer to Figure 1 , Figure 2 and Figure 3The embodiment of the present application discloses a waterproof heat dissipation light source which can be applied to the optical detection process of medical solvent and can be placed below the solvent and light the bottom of the solvent. Specifically, the waterproof heat dissipation light source comprises a mounting seat 100, a transparent cover plate 200, a lamp bead plate 300 and a heat dissipation piece 400. The mounting seat 100 is the basic component of the waterproof heat dissipation light source and can provide a mounting basis for the transparent cover plate 200, the lamp bead plate 300 and the heat dissipation piece 400. The mounting seat 100 has a containing cavity 111 and an opening in communication with the containing cavity 111. The lamp bead plate 300 is arranged in the containing cavity 111. The lamp bead plate 300 is attached to the bottom wall of the containing cavity 111. The light emitting direction of the lamp bead plate 300 is towards the opening of the mounting seat 100. The mounting seat 100 is provided with a stepped surface 121 at the opening. The transparent cover plate 200 is carried on the stepped surface 121. The joint between the transparent cover plate 200 and the stepped surface 121 is sealed by glue.

[0029] In the embodiment of the present application, the heat dissipation piece 400 is connected and fixed with the mounting seat 100. The heat dissipation piece 400 is arranged at one end of the mounting seat 100 away from the opening. The heat dissipation piece 400 has a hollow channel 411 in communication with the containing cavity 111. The wire harness connected with the lamp bead plate 300 is arranged in the hollow channel 411.

[0030] Based on the above technical scheme, the transparent cover plate 200 is carried on the stepped surface 121 of the mounting seat 100. The sealing is realized by the glue joint between the transparent cover plate 200 and the mounting seat 100. The leakage of the solvent can be effectively prevented from entering the containing cavity 111 through the gap between the mounting seat 100 and the transparent cover plate 200, which affects the optical performance and even damages the lamp bead plate 300. The leakage problem caused by the aging deformation or improper installation of the waterproof shell or O-shaped sealing ring is avoided. At the same time, the heat generated by the lamp bead plate 300 during work is rapidly conducted to the mounting seat 100. The heat dissipation piece 400 protects the wire harness. The direct contact between the heat dissipation piece 400 and the mounting seat 100 can rapidly conduct the heat of the mounting seat 100 to the surrounding environment. The rapid cooling of the lamp bead plate 300 is realized. The temperature rise of the whole waterproof heat dissipation light source is not obvious. The service life of the whole waterproof heat dissipation light source is prolonged.

[0031] In the embodiment of the present application, the mounting seat 100 can be threadedly connected with the heat dissipation piece 400. The mounting seat 100 is provided with a threaded hole at one end away from the opening. The threaded hole can be coaxially arranged with the aforementioned containing cavity 111. One end of the heat dissipation piece 400 away from the mounting seat 100 is provided with an external thread. The external thread of the heat dissipation piece 400 is threadedly matched with the threaded hole of the mounting seat 100 to realize the connection and fixation of the mounting seat 100 and the heat dissipation piece 400. The threaded connection has the characteristics of convenient assembly and use.

[0032] In the embodiment of the present application, the waterproof heat dissipation light source further comprises a wire harness connector 500 connected to the end of the heat dissipation member 400 away from the mounting base 100 to close the hollow channel 411, thereby ensuring the airtightness of the entire hollow channel 411. For example, the heat dissipation member 400 is provided with a positioning groove at the end thereof away from the mounting base 100, the positioning groove being in communication with the hollow channel 411, the opening size of the positioning groove being greater than that of the hollow channel 411, the wire harness connector 500 being positioned and fitted in the positioning groove, and the wire harness connector 500 being connected and fixed to the heat dissipation member 400 by a threaded connection. Of course, in other embodiments of the present application, the wire harness connector 500 can also be directly connected and fixed to the heat dissipation member 400 by a threaded fitting.

[0033] In a further technical solution, the junction of the mounting base 100 and the heat dissipation member 400 is provided with sealing glue, and the junction of the wire harness connector 500 and the heat dissipation member 400 is provided with sealing glue. By providing the sealing glue, the airtightness of the entire waterproof heat dissipation light source can be improved, and external moisture can be prevented from entering the internal space of the entire light source to affect the use performance of the light source.

[0034] In the embodiment of the present application, please continue to refer to Figure 1 and Figure 2 , the heat dissipation member 400 comprises a columnar base body 410 and heat dissipation fins 420 connected to the columnar base body 410, wherein the hollow channel 411 is formed in the columnar base body 410, and the extension direction of the hollow channel 411 can be coaxial or parallel to the columnar base body 410, and the heat dissipation fins 420 can be a plurality of heat dissipation fins integrally connected to the columnar base body 410, the plurality of heat dissipation fins 420 being distributed along the circumference of the columnar base body 410 at the outer periphery of the columnar base body 410. The heat generated by the lamp bead plate 300 can be transmitted to the heat dissipation member 400 through the mounting base 100, or through the air in the hollow channel 411. The plurality of heat dissipation fins 420 distributed along the circumference of the columnar base body 410 can significantly increase the heat dissipation surface area of the entire heat dissipation member 400, thereby accelerating the dissipation of heat. For example, the heat dissipation member 400 can be a structural member made of aluminum or aluminum alloy material, or the heat dissipation member 400 can also be a structural member made of copper material.

[0035] In the embodiments of the present application, the mounting seat 100 can be of an integrated structure or a split structure. In the preferred embodiments of the present application, the mounting seat 100 is of a split structure. Specifically, the mounting seat 100 includes a base 110 and a ring-shaped member 120. The base 110 is of an open structure with one end open. The ring-shaped member 120 is sleeved on the radially outer side of the base 110 and is threadedly connected with the base 110. The lamp bead plate 300 is arranged in the base 110. The stepped surface 121 is arranged on the ring-shaped member 120. In this way, when the lamp bead plate 300 is damaged, the ring-shaped member 120 can be rotated to be separated from the base 110. Then, the lamp bead plate 300 in the base 110 can be repaired or replaced. This split design can repair or replace the lamp bead plate 300 without disassembling other components such as the transparent cover plate 200 and the heat dissipation member 400, thereby avoiding the problems of reduced sealing performance or damaged components caused by frequent disassembly.

[0036] In further technical solutions, a heat-conducting layer (not shown in the figure) is arranged between the lamp bead plate 300 and the base 110. The heat-conducting layer can be heat-conducting silicone grease. The heat-conducting silicone grease can fill the small gaps between the lamp bead plate 300 and the base 110. The heat-conducting layer can increase the heat transfer efficiency between the lamp bead plate 300 and the base 110. The heat generated by the lamp bead plate 300 can be rapidly conducted to the surrounding environment through the mounting seat 100 and the heat dissipation member 400.

[0037] In further technical solutions, please refer to Figure 3 The ring-shaped member 120 also has a guide surface 122 adjacent to the stepped surface 121. When the transparent cover plate 200 is supported on the stepped surface 121, the guide surface 122 has a radial gap 123 with the edge of the transparent cover plate 200. In this way, when the transparent cover plate 200 is glued to the stepped surface 121, glue can also be injected into the radial gap 123. In this way, the sealing performance between the transparent cover plate 200 and the mounting seat 100 can be improved.
