Technical Field

The utility model relates to the technical field of automobile illumination, in particular to a car lamp with a large illumination angle.

Furthermore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 2 and 3, a vehicle lamp with a large illumination angle includes: outer lamp shade 1, interior lamp shade 2, speculum 4, light source and casing 6. The outer lampshade 1 is fixedly mounted on the housing 6 (for example, it can be fixed by screws), and the outer lampshade 1 and the housing 6 form a closed cavity. The reflector 4 is arranged in the closed cavity, and the reflector 4 is fixedly connected with the shell 6. The inner lampshade 2 is arranged in the closed cavity, the inner lampshade 2 is positioned between the reflector 4 and the outer lampshade 1, and the inner lampshade 2 is fixed on the shell 6 (for example, can be fixed by screws). In other words, the lamp structure comprises an outer lamp cover 1, an inner lamp cover 2, a reflector 3, a light source and a shell 6 from front to back. Wherein, the inner lampshade 2 is provided with a first reflection pattern 3 at one side close to the shell 6, the side wall of the reflector 4 is provided with a second reflection pattern 5, and the light rays directly or reflected by the light source (also positioned in the closed cavity and not shown in the figure) are reflected by the first reflection pattern 3 and the second reflection pattern 5 in sequence to form the light rays with the irradiation angle larger than 80 degrees, thereby meeting the requirements of the regulations. The first reflective patterns 3 and the second reflective patterns 5 may be in the shape of stripes, corn grains, diamonds, etc., and may be arranged according to actual requirements.

In the present embodiment, the inner housing 2 includes a first mounting surface 21, the first reflective pattern 3 is mounted on the first mounting surface 21, the second reflective pattern 5 is disposed on a sidewall of the reflector 4, and an included angle formed between the first mounting surface 21 and the sidewall of the reflector 4 is an acute angle. Specifically, the first mounting surface 21 is located at an edge position of the inner lamp housing 2, and the side wall of the reflector 4 is close to the first mounting surface 21. The first and second

reflective patterns

3 and 5 may be hidden when the user is standing directly in front of the vehicle lights. A part of light emitted by the light source can be reflected to the second reflective pattern 5 by the first reflective pattern 3, and then the light is reflected to the outer lampshade 1 by the second reflective pattern 5 to be emitted. Therefore, the light emitted by the light source can form a light-emitting angle of 89.35 degrees after being reflected twice, the angle is an included angle between the light and the horizontal direction, and the requirement that the outward angle is not less than 80 degrees, which is required by the GB5920-2019 standard, is met.

In this embodiment, the orthographic projection of the first pattern 3 on the side wall of the mirror 4 partially overlaps the second pattern 5. The purpose of this is that when the light from the light source strikes the edge of the first reflective pattern 3 (the edge is the edge near the side wall of the reflector 4), the light can still be reflected onto the second reflective pattern 5 and then reflected by the second reflective pattern 5.

In the present embodiment, the angle between the outer bulb 1 and the horizontal plane is β, β >38 °, for example 38.2 °. In other words, the slope of the outer cover 1 of the present embodiment is slightly greater than the slope of a general outer cover, so that the first reflective pattern 3 and the second reflective pattern 5 can be hidden well, the appearance of the whole shape of the vehicle lamp can be maintained, and the light can be emitted at a large angle.

In one embodiment, the first reflective pattern 3 is integrally formed with the first mounting surface 21, and the second reflective pattern 5 is integrally formed with the second mounting surface 22. For example, the reflective pattern may be formed on the surface of the inner lamp housing 2 through a process.

In one embodiment, the first reflective pattern 3 and the second reflective pattern 5 are separate components (e.g., separate aluminum-plated components, as shown in fig. 3), the first reflective pattern 3 is detachably connected to the first mounting surface 21, and the second reflective pattern 5 is detachably connected to the second mounting surface 22, for example, by a snap, a screw, a rivet, or a slider, so as to facilitate the detachment and position adjustment.

In summary, according to the vehicle lamp with a large illumination angle, the inner lampshade 2 and the reflector 4 are simultaneously provided with the reflective patterns, light emitted by the light source is reflected by the first reflective pattern 3 and the second reflective pattern 5 in sequence, so that light with an angle larger than 80 degrees can be formed, the requirements of regulations are met, meanwhile, the inner lampshade 2 is provided with the reflective patterns, so that the light becomes soft, and the safety of driving at night is improved. Secondly, the first reflective pattern 3 and the second reflective pattern 5 can be hidden, and the appearance of the vehicle lamp cannot be influenced; the first reflection patterns 3 can be flexibly designed into a detachable or sliding block mode according to the size of a specific actual space, and are convenient to replace and adjust. The reflecting pattern of the present invention is suitable for use in vehicle lamp structure with outer lamp cover with great inclination.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations can be made by the worker in the light of the above teachings without departing from the spirit of the utility model. The technical scope of the present invention is not limited to the content of the specification, and must be determined by the scope of the claims.
