[0032] In order to make the purpose, technical scheme and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the drawings and examples.

[0033] Please refer to Figures 1 to 6 The utility model discloses a waterproof light source, including lamp holder 1, lamp board 2, diffusion plate 3 and at least two sealing rings 4, wherein the outer surface of lamp holder 1 is provided with mounting hole 13, mounting hole 13 can be the through hole or the threaded hole, through the screw and set up in mounting hole 13 can be fixed lamp holder 1 in the specified position, in addition, the open mounting groove 11 is provided on lamp holder 1, and lamp board 2 is fixed in mounting groove 11, and lamp board 2 can be understood as a plurality of light-emitting diodes in the electrified state are set on a circuit board, wherein diffusion plate 3 covers the slot of mounting groove 11, and diffusion plate 3 is used to reflect the light emitted by lamp board 2 outward in the way of diffuse reflection, to improve the uniformity of illumination, and a plurality of sealing rings 4 are all arranged between lamp holder 1 and diffusion plate 3 and are all arranged on the periphery of the slot of mounting groove 11, and diffusion plate 3 is fixedly connected with lamp holder 1 by connecting fastener, and diffusion plate 3 and lamp holder 1 jointly hold a plurality of sealing rings 4, so that a plurality of sealing rings 4 are all in the compressed state. In addition, at least two adjacent sealing rings 4 are provided with annular protruding block structure 5 separating the two sealing rings 4.

[0034] Specifically, the present scheme sets a plurality of sealing rings 4 between diffusion plate 3 and lamp holder 1, and each sealing ring 4 corresponds to a waterproof structure, that is, the present scheme sets multiple waterproof structures, thereby greatly reducing the risk of external water mist entering the mounting groove 11 and damaging the lamp board 2, and further greatly improving the waterproof performance of the light source. In addition, the present scheme also sets annular protruding block structure 5 between the two adjacent sealing rings 4, so that when an outer sealing ring 4 fails, the external water mist needs to pass through the protruding block structure 5 before it can penetrate into the next inner sealing ring 4. As can be seen, each protruding block structure 5 also corresponds to a waterproof structure, and by setting the protruding block structure 5 between the two adjacent sealing rings 4, the risk of external water mist entering the mounting groove 11 and damaging the lamp board 2 can be further reduced, and the waterproof performance of the light source is further improved. In summary, the light source of the present scheme has strong waterproof performance and can meet the long-time lighting demand in extremely humid environment.

[0035] Please refer to Figure 1 and Figure 5 The waterproof light source further comprises a waterproof connector 6 fixed on the outer wall of the lamp holder 1, and the lamp plate 2 is electrically connected with the waterproof connector 6. By arranging the waterproof connector 6, the external water mist can be prevented from entering the installation groove 11 under the premise that the anode and the cathode of the lamp plate 2 are led outwards.

[0036] Please refer to Figures 1 to 6 The side of the lamp holder 1 facing the diffusion plate 3 is provided with at least two annular waterproof grooves 12, and each waterproof groove 12 is provided with one of the sealing rings 4. In this embodiment, only two sealing rings 4 are arranged between the lamp holder 1 and the diffusion plate 3, that is, the annular protrusion structure 5 is arranged, and only two waterproof grooves 12 are arranged on the lamp holder 1. By arranging the waterproof grooves 12, the positions of the sealing rings 4 can be stabilized, and the sealing rings 4 are compressed and deformed by the lamp holder 1 and the diffusion plate 3, thereby improving the waterproof reliability of the sealing rings 4. In other embodiments, the waterproof grooves 12 can not be arranged on the lamp holder 1, and the waterproof grooves 12 can be arranged on the side of the diffusion plate 3 facing the lamp holder 1.

[0037] Please refer to Figures 1 to 6 Between the two adjacent waterproof grooves 12, the side of the lamp holder 1 facing the diffusion plate 3 is provided with the protrusion structure 5, and the side of the diffusion plate 3 facing the lamp holder 1 is provided with the annular groove 31, and the protrusion structure 5 is inserted into the annular groove 31. By adopting such a design, when one of the sealing rings 4 around the protrusion structure 5 fails, the external water mist cannot immediately penetrate the next sealing ring 4 in the inner circle, and the external water mist will be blocked by the protrusion structure 5 and penetrate into the gap between the protrusion structure 5 and the annular groove 31. Only when the amount of external water mist is sufficient can the external water mist penetrate over the protrusion structure 5 and penetrate into the next sealing ring 4 in the inner circle. Please refer to Figure 7 Preferably, the depth L of the annular groove 31 is 4.5 mm, so that the protrusion structure 5 can be inserted into the annular groove 31 with a higher height, which is beneficial to improve the waterproof property of the protrusion structure 5. The thickness M of the diffusion plate 3 in this embodiment is as Figure 7The thickness of the diffusion plate 3 is preferably 8mm, and the diffusion plate 3 with the thickness of 8mm can process the annular groove 31 with a diameter of 4.5mm, and has sufficient thickness to reflect the light emitted by the lamp plate 2 outward. Preferably, the distance N between the side wall of the bump structure 5 and the side wall of the annular groove 31 is 0.5mm, and the distance O between the end face of the bump structure 5 facing the groove bottom of the annular groove 31 and the bottom face of the groove bottom of the annular groove 31 is also 0.5mm. By such design, when the lamp holder 1 and the diffusion plate 3 are assembled with each other, the problem of mutual interference between the bump structure 5 and the inner wall of the annular groove 31 can be prevented, and the reliability of the lamp holder 1 and the diffusion plate 3 to jointly hold the plurality of sealing rings 4 can be ensured, so as to ensure the stronger waterproof performance of the light source. Preferably, the cross-sectional area of the waterproof groove 12 is equal to the cross-sectional area of the sealing ring 4, so that after the lamp holder 1 and the diffusion plate 3 jointly hold the sealing ring 4, the lamp holder 1 and the diffusion plate 3 can abut against each other and make the sealing ring 4 fill the waterproof groove 12 as much as possible, thereby being beneficial to improving the waterproof performance of the light source. Preferably, the sealing ring 4 is a butyl rubber ring with a cross-sectional diameter of 2mm. Butyl rubber has the characteristics of lifelong non-curing, has extremely strong adhesion to various material surfaces, and has good weather resistance and aging resistance.

[0038] Please refer to Figures 3 to 7 , the lamp holder 1 is provided with the first inclined surface 14 inclined to the direction of gravity on the side facing the diffusion plate 3, and the first inclined surface 14 surrounds the outer periphery of the outermost sealing ring 4, and the diffusion plate 3 is provided with the second inclined surface 32 abutting with the first inclined surface 14 on the side facing the lamp holder 1. By abutting the first inclined surface 14 and the second inclined surface 32, the first inclined surface 14 and the second inclined surface 32 can be used as the first line of defense to prevent external water mist from entering, and the waterproof performance of the light source is further improved. At the same time, since the first inclined surface 14 and the second inclined surface 32 are both inclined along the direction of gravity, even if water mist enters between the first inclined surface 14 and the second inclined surface 32 and forms water droplets, the water droplets will fall to the outside due to their own gravity, so it is difficult for the water droplets to accumulate between the lamp holder 1 and the diffusion plate 3, thereby further improving the waterproof performance of the light source. Preferably, the first inclined surface 14 and the second inclined surface 32 are designed as smooth surfaces, so as to ensure that the water droplets formed between the first inclined surface 14 and the second inclined surface 32 can slide outward due to their own gravity, thereby improving the waterproof performance.

[0039] The above is only a preferred embodiment of the present application, and only the technical principle of the present application is specifically described. These descriptions are only for explaining the principle of the present application, and cannot be used to limit the protection scope of the present application in any way. Based on the explanations herein, any modification, equivalent replacement and improvement within the spirit and principle of the present application, and other specific embodiments of the present application which can be thought by those skilled in the art without creative labor, should be included in the protection scope of the present application.
