[0003] The U-shaped warning lights currently in circulation on the market use U-shaped lenses. The effective optical path of this lens has an inclination deviation, which easily leads to low luminous efficiency of the signal light, and the emitted U-shaped light is not clear enough, which is not conducive to people's use. Utility Model Content

[0004] In view of the above-mentioned shortcomings, the purpose of the present utility model is to provide a novel U-shaped light warning lamp, which has good light gathering effect, clear light pattern, high luminous efficiency, and is more convenient for people to use.

[0005] The technical solution adopted by the utility model to achieve the above-mentioned purpose is:

[0006] A novel U-shaped warning light comprises a semi-annular lens and a warning light source arranged below the semi-annular lens, wherein the position of the warning light source coincides with the focal position of the semi-annular lens.

[0007] As a further improvement of the present invention, the semi-annular lens as a whole is a half-annular structure formed by cutting the annular body structure from the midline.

[0008] As a further improvement of the present invention, the outer surface of the semi-annular lens is formed with an outer convex arc surface extending outward, and an inner concave surface formed at the center of the outer convex arc surface.

[0009] As a further improvement of the present invention, the interior of the semi-annular lens is formed with an inner plane matching the inner concave surface, and an inner incident surface formed outside the inner plane and extending obliquely inwardly and downwardly.

[0010] As a further improvement of the utility model, the warning light source is arranged obliquely below the inner plane.

[0011] As a further improvement of the present invention, the light source of the warning light is an LED lamp bead.

[0012] The beneficial effects of the utility model are:

[0013] By configuring the U-shaped light warning lamp to include a semi-annular lens and a warning light light source arranged below the semi-annular lens, the position of the warning light light source coincides with the focal position of the semi-annular lens. The configuration of the semi-annular lens enables the luminous point of the light source to be an imaging condenser lens in any cross-section of the semi-annular lens, which is beneficial to focusing the light, and the position of the light source coincides with the focal position of the semi-annular lens, so that the light pattern emitted by the U-shaped light warning lamp is clear and has high light efficiency.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0024] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Please refer to Figures 1 to 5 The embodiment of the utility model provides a novel U-shaped warning light, comprising a semi-circular lens 1, and a warning light source 2 arranged below the semi-circular lens 1, wherein the position of the warning light source 2 coincides with the focal position of the semi-circular lens 1. The arrangement of the semi-circular lens 1 enables the light source emitting point to be an imaging condenser lens for any cross section of the semi-circular lens 1, which is conducive to gathering light, and the position of the light source coincides with the focal position of the semi-circular lens 1, so that the light pattern emitted by the U-shaped warning light is clear and has high light efficiency.

[0026] For the specific structural setting of the semi-annular lens 1, Figure 1 As shown, the semi-annular lens 1 is a half-annular structure formed by cutting the annular structure from the midline, so that it is more compatible with the warning light source 2 arranged below the semi-annular lens 1, which is conducive to focusing the light emitted by the warning light source 2 into an image, so that the light pattern emitted by the U-shaped light warning light is clear and has high light efficiency. On this basis, the redundant lens structure is reduced, thereby reducing the occupied space, making the structure of the U-shaped light warning light more compact and reducing the production cost.

[0027] For the external structure of the semi-annular lens 1, Figure 1 and Figure 2 As shown, the outer surface of the semi-annular lens 1 is formed with an outer convex arc surface 11 protruding outward, and an inner concave surface 12 formed at the center of the outer convex arc surface 11, and the inner concave surface 12 is arranged at the outer center of the semi-annular lens 1. The light emitted by the warning light light source 2 is refracted differently at different angles of the outer convex arc surface 11 and the inner concave surface 12, and the light emitted by the warning light light source 2 is focused, so that the light pattern emitted by the U-shaped light warning lamp is clear and the light efficiency is high.

[0028] Regarding the structural setting of the inner concave surface 12, as shown in FIG. Figure 1 and Figure 2 As shown, the inner concave surface is a plane.

[0029] For the internal structure of the semi-annular lens 1, Figure 1 and Figure 2 As shown, the interior of the semi-annular lens 1 is formed with an inner plane 13 matching the inner concave surface 12, and an inner incident surface 14 formed outside the inner plane 13 and extending obliquely inward and downward, the inner plane 13 cooperates with the inner concave surface 12, and the inner incident surface 14 cooperates with the outer convex arc surface 11, and the light emitted by the warning light light source 2 first passes through the inner incident surface 14 to enter the outer convex arc surface 11 for refraction, or the light passes through the inner plane 13 to enter the inner concave surface 12 for refraction, and the two structures cooperate with each other to make the light emitted by the warning light light source 2 refract differently at different angles on the side wall and the middle part of the semi-annular lens 1, thereby focusing the light emitted by the warning light light source 2 respectively, so that the light pattern emitted by the U-shaped light warning lamp is clear and has high light efficiency.

[0030] For the specific lighting setting of the warning light source 2, as shown in FIG. Figure 1 and Figure 2 As shown, the warning light source 2 is tilted below the inner plane 13, so as to match the half semi-circular structure of the semi-circular lens 1. The light emitted by it irradiates the half semi-circular structure accordingly. The light-emitting point is an imaging condenser lens for any cross-section of the semi-circular lens 1, which is conducive to focusing the light. Its position coincides with the focal position of the semi-circular lens 1, so that the light pattern emitted by the warning light source 2 is clear and the light efficiency is high.

[0031] As for the specific structural setting of the warning light source 2, the warning light source 2 can be an LED lamp bead, which is low in price and has good durability, effectively reducing the production cost and ensuring the service life of the U-shaped light warning lamp.

[0032] Regarding the installation method of the warning light source 2 and the semi-annular lens 1, the warning light source 2 and the semi-annular lens 1 can be installed on a substrate or a bracket respectively, and the installation method can be selected according to actual conditions, so no specific limitation is made in this embodiment.

[0033] It should be noted that the new U-shaped warning light disclosed in the utility model is an improvement on the specific structure, and the specific control method is not the innovation point of the utility model. The LED light source and other components involved in the utility model can be general standard parts or components known to those skilled in the art, and their structure, principle and control method are all known to those skilled in the art through technical manuals or conventional experimental methods.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, other structures obtained by adopting the same or similar technical features as the above embodiments of the present invention are within the protection scope of the present invention.
