Description

[Technical Field]

[0001] The present invention relates to a light diffusing member for an underwater light that is attached to a light used underwater to diffuse the light. [Background technology]

[0002] Underwater lights used underwater during diving and other activities are known. Underwater lights illuminate dark waters brightly, ensuring a diver's visibility, and can also be used to signal other divers and ensure safety. Patent Document 1, for example, lists such underwater lights. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Special Publication No. 2014-503840 Summary of the Invention [Problem to be solved by the invention]

[0004] Underwater lights are divided into wide-angle types that have a wide beam angle and can illuminate a wide area, and spot-type types that have a narrow beam angle and can illuminate a small area. However, in both cases, the light is emitted forward from the underwater light, so it cannot be seen from the side. Visibility from the side is sometimes necessary when sending signals between multiple divers, which has been inconvenient with conventional underwater lights.

[0005] The present invention has been made to solve the above-mentioned problems, and has an object to provide a light diffusing member for an underwater light that can make the underwater light visible from the side. [Means for solving the problem]

[0006] The light diffusing member for an underwater light according to the present invention, which achieves the above object, is attached to an underwater light having a light source that irradiates light forward, and diffuses the light to the side, and has a translucent tubular main body, one end of which has a fixing part that can be fixed to the underwater light, and the other end of which has an end surface part with a hole in the center, and by fixing the fixing part to the underwater light, the main body is arranged to surround the side of the light irradiated from the light source, and the end surface part is arranged to face the light source. The main body is colored yellow, and has a string-like connecting part that connects the underwater light to the main body. . [Effects of the Invention]

[0007] The light diffusing member for underwater lights constructed as described above irradiates light from the light source forward through the holes in the end surface and diffuses a portion of the light to the side by the main body, thereby improving visibility from the side while ensuring forward illumination of the light. This improves convenience when sending signals between multiple divers, for example.

[0008] The main body may be colored yellow, which causes the light diffused laterally to be yellow, improving visibility underwater.

[0009] The end surface may be translucent, which allows the light from the underwater light to be diffused over a wider area.

[0010] The hole may have a diameter equal to or greater than half the diameter of the end surface, thereby enabling the light emitted forward from the underwater light to be sufficiently irradiated forward.

[0011] The main body may have a connecting part that connects the underwater light to the main body, thereby preventing the light diffusing member from falling off the underwater light. [Brief explanation of the drawings]

[Figure 5] FIG. 10 is a perspective view of a light diffusing member for an underwater light according to a modified example. DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the dimensional proportions in the drawings may be exaggerated for the sake of explanation and may differ from the actual proportions.

[0014] As shown in FIGS. 1 and 2, the light diffusing member 10 according to this embodiment has a cylindrical main body 20. The main body 20 is cylindrical and has the same diameter along its length, with a space 21 formed inside. One end of the main body 20 is open. An end surface 23 is formed at the other end of the main body 20. The end surface 23 has a hole 24 in its center that connects the space 21 with the outside. The hole 24 in the end surface 23 has a diameter that is at least half the diameter of the end surface 23.

[0015] The main body 20 and the end surface 23 are integrally formed. However, the main body 20 and the end surface 23 may be formed by combining separate parts. The main body 20 and the end surface 23 are formed from a translucent resin material. This resin material is colored yellow. However, the color of the main body 20 and the end surface 23 is not limited to yellow and may be other colors.

[0016] One open end of the main body 20 has a mounting portion 22 that is attached to the underwater light 100. The mounting portion 22 has an inner diameter that allows the inner circumferential surface to be engaged with the underwater light 100.

[0017] The main body 20 has a string-like connecting part 25 extending from the periphery. The connecting part 25 is made of flexible rubber, thread, etc. A tip 25a of the connecting part 25 is formed in a loop shape so that it can be hooked onto the underwater light 100.

[0018] As shown in Figure 3, the underwater light 100 has a light source 101 that emits light forward. The underwater light 100 also has a cylindrical part 102 in front of the light source 101. The underwater light 100 has a handle part 103 that the user can hold in their hand, and a hook part 104 that is formed in a protruding shape.

[0019] The fixing portion 22 of the main body 20 is formed so that the inner diameter is approximately the same as the outer diameter of the cylindrical portion 102, and by inserting the cylindrical portion 102 into the fixing portion 22, the main body 20 can be fixed to the underwater light 100. In addition, by hooking the tip portion 25a of the connecting portion 25 of the light diffusing member 10 onto the hook portion 104 of the underwater light 100, the light diffusing member 10 can be prevented from falling off the underwater light 100.

[0020] 4, by attaching the light diffusing member 10 to the underwater light 100, the tubular portion 102 of the underwater light 100 is housed in the space 21 of the light diffusing member 10, and the main body 20 is arranged to surround the sides of the light emitted from the light source 101. In addition, the end surface 23 is arranged to face the light source 101. As a result, the light from the light source 101 is emitted forward through the hole 24 of the end surface 23, and some of the light is diffused laterally by the main body 20.

[0021] In this way, by attaching the light diffusing member 10 to the underwater light 100, the light from the underwater light 100 is emitted forward while a portion of it is diffused to the side, thereby improving visibility from the side while ensuring forward light emission. This improves convenience when, for example, sending signals between multiple divers.

[0022] Here, the color of the main body 20 is the color of the light that is diffused laterally. As mentioned above, the main body 20 is colored yellow. The yellow color of the diffused light improves visibility underwater.

[0023] Furthermore, since the hole 24 has a diameter that is half or more the diameter of the end surface 23, the light that travels forward from the underwater light 100 can be sufficiently irradiated forward.

[0024] Furthermore, since the end surface portion 23 is also translucent, the light from the underwater light 100 can be diffused over a wider area.

[0025] 5, the light diffusing member 50 does not need to have a hole in the end surface portion 52 provided at the end of the main body portion 51. In this case, although the light emitted forward from the underwater light 100 becomes weaker, the light is more diffused to the sides, improving visibility from all directions.

[0026] The present invention is not limited to the above-described embodiment, and various modifications can be made by those skilled in the art within the technical concept of the present invention. [Explanation of symbols]
