Description

Technical Field

[0001] The utility model relates to the technical field of ship lamps, in particular to a high-illuminance ship mast lamp lens and a mast lamp. Background Art

[0002] A ship mast lamp is a type of ship identification light. The identification light is a recognition mark for a ship during sea navigation. The mast lamp is a white lamp above the center line of the ship's bow and stern and can be continuously displayed within a 225° horizontal arc. Therefore, in the design of the mast lamp lens, strong illuminance is required in a certain direction to achieve the indication function.

[0003] The traditional mast lamp light source uses a halogen lamp. The entire light source is relatively large and the light emission is relatively scattered. The mast lamp generally needs to emit light from the side, so the light at the top is wasted relatively seriously; the entire lamp is also relatively bulky and expensive. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a high-illuminance ship mast lamp lens and a mast lamp, which can optimize the light of the light source, enable the mast lamp using the lens to have better illuminance, illuminate farther and brighter, and improve the service life of the lamp.

[0005] In order to achieve the above purpose, the solution of the utility model is:

[0006] A high-illuminance ship mast lamp lens,

[0007] including a lens main body and a mounting main body;

[0008] The lens main body includes a columnar lens on the upper side and a TIR lens on the lower side; a conical groove is recessed at the top of the columnar lens, the groove wall of the conical groove is a free surface, and the outer lens wall of the columnar lens also adopts a free surface; the middle part of the bottom of the TIR lens is a convex lens;

[0009] The mounting main body is a hollow structure; the upper part of the mounting main body is annularly arranged around the outer periphery of the TIR lens, and the top of the mounting main body is connected to the lower end of the columnar lens of the lens main body; an installation groove located below the TIR lens is arranged inside the lower part of the mounting main body.

[0010] Further, a mounting ring extends radially from the outer wall of the mounting main body.

[0011] Further, a chamfer is provided at the lower edge of the outer end of the mounting ring.

[0012] Further, the upper part of the mounting main body is a circular ring, and the lower part of the mounting main body is a rectangular ring.

[0013] Further, a plurality of convex ribs extending up and down are circumferentially spaced on the groove wall of the installation groove.

[0014] The present utility model further provides a high - illumination ship mast lamp, which includes the mast lamp lens and the LED light source; the LED light source is installed in the installation groove; glue is filled in the installation groove to fix the LED light source and simultaneously seal the lower opening of the installation groove.

[0015] Furthermore, the LED light source adopts 3030 lamp beads or 3535 lamp beads.

[0016] After adopting the above - mentioned technical solution, during use, the light source is installed in the installation groove, and the light emitted by the light source passes through the TIR lens and then exits from the side wall of the columnar lens; since the middle part at the bottom of the TIR lens uses a convex lens for light concentration, the light in the middle part can be collimated and emitted after passing through the convex lens, and the circumferential side of the TIR lens adopts the TIR light - concentration scheme, and the light on the side part is collimated and emitted after refraction and reflection by the TIR lens. Through such a design, more light emitted by the light source can be utilized, improving the light efficiency. And the conical groove and the outer side wall of the columnar lens above adopt the free - form surface optimization technology to better control the light angle. After the light directly emitted by the TIR lens is reflected by the free - form surface, it exits parallel from the side, increasing the light intensity value within the effective angle, enabling it to irradiate farther and brighter, effectively improving the illuminance of the light source and better playing an indicating role.

[0017] Moreover, filling glue in the installation groove of the mast lamp lens can fix the light source, improve the heat dissipation capacity of the light source, extend the service life of the light source, and adopt an integrated optical and heat - dissipation design, avoiding the need to specifically design a heat - dissipation structure, reducing the design size of the lamp, and saving costs.

[0018] Meanwhile, it can also isolate external water vapor or corrosive gases, prevent the components on the light source board from being corroded, improve the service life of the lamp, and be more suitable for working in a marine environment. Brief Description of the Drawings

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations.

[0031] As Figures 1 to 6 , a high-intensity ship mast lamp lens 10 in this embodiment includes a lens body 1 and a mounting body 2.

[0032] The lens body 1 includes a columnar lens 11 on the upper side and a TIR lens 12 on the lower side; a conical groove 111 is recessed at the top of the columnar lens 11, the groove wall of the conical groove 111 is a free surface, and the outer lens wall 112 of the columnar lens 11 also uses a free surface; the middle part of the bottom of the TIR lens 12 is a convex lens 121; the mounting body 2 is a hollow structure; the upper part 21 of the mounting body 2 is disposed around the outer periphery of the TIR lens 12, and the top of the mounting body 2 is connected to the lower end of the columnar lens 11 of the lens body 1; an installation groove 23 located below the TIR lens 12 is provided inside the lower part 22 of the installation body 2.

[0033] Refer to Figure 7 , during use, the light source 3 is installed in the installation groove 23, and the light emitted by the light source 3 is emitted from the outer lens wall 112 of the columnar lens 11 after passing through the TIR lens 12; specifically, refer to Figure 6, at the middle of the bottom of the TIR lens 12, a convex lens 121 is used for condensing light. The light in the middle part can be collimated and emitted after passing through the convex lens 121. The circumferential side of the TIR lens 12 adopts a TIR light condensing scheme. The light on the side part is collimated and emitted after being refracted and reflected by the TIR lens 12. Through such a design, more light emitted by the light source 3 can be utilized, improving the light efficiency. For the conical groove 111 and the outer lens wall 112 of the upper cylindrical lens 11, a free-form surface optimization technology is adopted to better control the light angle. After the light directly emitted by the TIR lens 12 is reflected by the free-form surface, it is emitted parallel from the side, increasing the light intensity value within the effective angle, enabling it to illuminate farther and brighter, effectively improving the illuminance of the light source 3 and better playing an indicating role.

[0034] Moreover, the installation groove 23 of the mast lamp lens 10 can improve the heat dissipation capacity of the light source 3, extend the service life of the light source 3, with an integrated optical and heat dissipation design, avoiding the need for a dedicated heat dissipation structure, reducing the design size of the lamp, and saving costs.

[0035] Meanwhile, the installation groove 23 can also be potted with glue to fix the light source 3, and it can also isolate external water vapor or corrosive gases, preventing the components on the light source board from being corroded, improving the service life, and being more suitable for working in a marine environment.

[0036] In this embodiment, at the lowest middle part of the conical groove 111 of the cylindrical lens 11, the highest precision machining is adopted to avoid forming an overly large fillet after machining, preventing light from emitting from here.

[0037] In this embodiment, a mounting ring 24 extends radially outward from the outer wall of the mounting body 2. This facilitates snap-fixing the mast lamp lens 10 to a mast lamp housing (not shown in the figure). With this fixing method, the lens can be easily matched with different outer covers to obtain marine navigation lights with different illumination requirements. And a chamfer 241 is provided at the lower edge of the outer end of the mounting ring 24 to facilitate guiding installation.

[0038] As Figures 1 to 3 , in this embodiment, the upper part 21 of the mounting body 2 is a circular ring to facilitate connection with the lens body 1; while the lower part 22 of the mounting body 2 is a rectangular ring, and the mounting groove 23 is formed within the rectangular ring to facilitate taking the mounting body 2 for installation operations.

[0039] Moreover, a number of vertically extending ribs 231 are circumferentially spaced on the groove wall of the installation groove 23. In this embodiment, two ribs 231 are respectively provided on the four inner walls of the rectangular ring, which can ensure the stability of the potted glue and prevent it from falling off easily.

[0040] This embodiment also provides a high-intensity marine mast light, which includes the mast light lens 10 and the light source 3 described above. The light source 3 can adopt an LED light source 3, such as 3030 lamp beads or 3535 lamp beads. The LED light source 3 is installed in the installation groove 23. Glue is filled in the installation groove 23 to fix the LED light source 3 and at the same time seal the lower opening of the installation groove 23.

[0041] Thus, by means of the structure of the mast light lens 10, this mast light can have the advantages of high intensity, good heat dissipation, and long service life.

[0042] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, equivalent changes and modifications made without departing from the principle of the present invention should still fall within the protection scope of the present invention.
