Description

Technical Field

[0001] The invention belongs to the technical field of vehicle lamp accessories, and in particular relates to a multi-optical combined vehicle lamp lens. Background Art

[0002] ‌‌The headlight lens plays a vital role in the headlight lighting system. Its main functions include focusing, restricting the angle of light, improving lighting effects and safety, etc. The lens can gather the scattered light emitted by the bulb to form a more concentrated and brighter light, thereby greatly enhancing the brightness of the headlight and making the headlight shine farther. This focusing effect not only improves the lighting effect, but also makes driving safer at night.

[0003] As the safety of electric vehicles and bicycles becomes higher and higher, and the need for space design optimization is increasing, the design requirements for the lens itself are also getting higher and higher. Most of the current lenses are simple concave-convex mirror structures. Although they can control the angle of light irradiation and then focus the light, the light simply tends to the front, the field of view is small, and a lot of light in the headlights is not fully utilized, resulting in a small field of view of the road and the surrounding area. In order to solve the problem of small field of view, Fresnel lenses are currently used on the market. Fresnel lenses are a lens designed using the principles of light refraction and diffraction. The surface of the Fresnel lens has a series of concentric grooves from small to large. These grooves can concentrate the light at one point to form a central focus, or adjust the light into parallel light or concentrated light through each groove.

[0004] However, the above technical solution still does not effectively utilize light. Generally, it can only simply aggregate the light in front and cannot split the light at multiple levels. Especially in a limited space, it is difficult to split the light on the road surface, both sides, and the upper side, and the field of view is small. Therefore, it is very necessary to design a combined headlight lens that can perform multi-level splitting of multiple optics to expand the field of view. Summary of the invention

[0005] The present invention provides a variety of optical combined vehicle lamp lenses. The convex lens has an eccentric design with a larger bottom and a smaller top. The convex lens is used to focus light close to the road surface. The annular lens ring is designed to form a horizontal light coil outside the focused light of the convex lens. The horizontal light coil can increase the field of view of the convex lens, thereby being safer. By setting an annular light splitting part, the thickness of the upper and lower parts gradually decreases from the bottom to the top, so that the light is refracted to produce an upward inclined light splitting, thereby compensating for the upper field of view, so as to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a multi-optical combined headlight lens, comprising a lens body, a convex lens protruding from the middle of the front side of the lens body, and the convex lens aggregates the rear light source; the convex lens is an eccentric design with a larger bottom and a smaller top relative to the center of the lens body, and is used to focus the light close to the road surface; the lens body is provided with an annular lens ring outside the convex lens, and the annular lens ring is used to refract the light part that is irradiated outside the convex lens.

[0007] Preferably, the annular mirror ring is designed to have a gradually increasing width from the bottom to the top, and the width changes on both sides are mirror-symmetrical.

[0008] Preferably, the convex lens and the annular mirror ring are projected backward to cover the center of the lens body and are a circular area concentrically arranged with the lens body.

[0009] Preferably, the lens body is provided with an annular light splitting portion on the periphery of the annular lens ring, and the annular light splitting portion includes an upper and a lower part, and the thickness of the upper and lower parts gradually decreases from the bottom end to the top end.

[0010] Preferably, the thicknesses of the upper and lower annular light splitting parts decrease gradually to different degrees from the bottom to the top.

[0011] Preferably, the upper and lower parts of the annular light splitting portion are mirror-imaged on both sides.

[0012] Preferably, the annular light splitting portion is provided with longitudinal stripe grooves on the surface, and the stripe grooves on both sides are mirror-imaged.

[0013] Preferably, the lens body is provided with an inclined slope on the rear side.

[0014] Preferably, the lens body is provided with three connecting parts on the rear side.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The convex lens is an eccentric design with a larger bottom and a smaller top relative to the center of the lens body. It is used to focus light close to the road surface. The design of the annular mirror ring can form a horizontal light coil outside the focused light of the convex lens. The horizontal light coil can increase the field of view of the convex lens, making it safer.

[0016] 2. By setting an annular light splitter, the annular light splitter includes two parts, the thickness of the upper and lower parts gradually decreases from the bottom to the top, so that the light is refracted to produce an upward inclined light splitting, thereby compensating for the upper field of view.

[0017] 3. Two-layer light splitting is achieved through the annular light splitting parts in the upper and lower parts, so that the light distribution in the vertical space is more layered and the coverage is wider.

[0018] 4. Through the setting of longitudinal stripe grooves, the light emitted by the annular splitter can be separated into different light rays through the stripe grooves. Based on the principle of Fresnel lens, the light rays are layered to form different vertical light bands on both sides, thereby increasing the field of view on both sides and making the light uniform.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1The present invention provides a variety of optical combined headlight lenses, including a lens body 1, a convex lens 2 protruding from the middle of the front side of the lens body 1, the convex lens 2 aggregates the light from the rear light source, the light from the rear light source is dispersed in four directions, and the light in the middle can be focused to the irradiation point through the convex lens 2 in the middle, which is used to focus the light in the center; the convex lens 2 is an eccentric design with a larger bottom and a smaller top relative to the center of the lens body 1, and is used to focus the light close to the road surface, that is, the light is tilted downward, so that it is not only focused on the irradiation distance, but also focused on the road surface, so that when the lens body 1 is used on the headlight, such as the electric The high-speed vehicle light or the bicycle light can provide a better view of the road; the lens body 1 is provided with an annular lens ring 3 on the outside of the convex lens 2, and the annular lens ring 3 is used to refract the light part outside the convex lens 2. After refraction, the light is irradiated horizontally, which can be used to make up for the field of view after the convex lens 2 converges to the road surface. Since the convex lens 2 focuses the light, that is, the light is gradually aggregated, the irradiated field of view will gradually decrease, and the excess light is split through the annular lens ring 3, and the light can form a horizontal light coil outside the focused light of the convex lens 2. The horizontal light coil can increase the field of view irradiated by the convex lens 2, which is safer.

[0023] See also Figure 1-Figure 3 , the annular mirror ring 3 is designed to have a gradually increasing width from the bottom to the top, and the width changes on both sides are mirror-symmetrical; in the present embodiment, since the light focused by the convex lens 2 is an inclined focused light close to the road surface, and the intensity of the light above is low, although the annular mirror ring 3 irradiates a horizontal aperture to increase the field of view, the light intensity at the top is still insufficient. By designing the width to gradually increase from the bottom to the top, the amount of light entering the upper part of the annular mirror ring 3 will gradually increase, and then the upper part of the aperture illuminated by the annular mirror ring 3 will increase the irradiation range and brightness, which can further compensate for the situation that the upper field of view illuminated by the convex lens 2 gradually decreases.

[0024] See also Figure 2 The convex lens 2 and the annular mirror ring 3 are projected backward to cover the center of the lens body 1, and are a circular area concentrically arranged with the lens body 1. In this embodiment, the longitudinal arrangement of the light is achieved without occupying the entire space of the lens body 1, so that the light can be split while maintaining a sufficient viewing distance, thereby achieving a dual arrangement of the road surface and the front field of view.

[0025] See also Figure 1-Figure 3, the lens body 1 is provided with an annular light splitting part 4 on the periphery of the annular lens ring 3, and the annular light splitting part 4 includes an upper and a lower part, and the thickness of the upper and lower parts gradually decreases from the bottom to the top; in this embodiment, although the amount of light entering the annular lens ring 3 through the upper part gradually increases, the annular lens ring 3 increases the upper brightness by increasing the upper light amount. Since it is a horizontal light, it mainly plays a role in compensating the light intensity of the front field. By setting the annular light splitting part 4, the light part of the light source entering the convex lens 2 and the annular lens ring 3 can be split upward. Specifically, the annular light splitting part 4 includes an upper and a lower part, and the thickness of the upper and lower parts gradually decreases from the bottom to the top, so that the light is refracted and produces an upward tilted splitting, which can compensate for the upper field of view; two-layer splitting is achieved by the annular light splitting part 4 of the upper and lower parts. Since the light can only maintain one direction when the annular aperture 3 is tilted upward as a whole, the light distribution in the longitudinal space is more layered and the coverage is wider through the two-layer splitting.

[0026] See also Figure 3 The thickness of the upper and lower annular light splitting parts 4 decreases gradually from the bottom to the top to different degrees; in this embodiment, different inclinations are set for the upper and lower parts, so that the light of the upper and lower parts forms an angle, and the angle can be adjusted accordingly according to actual needs, thereby completing the upper light adjustment for different needs.

[0027] See also Figure 2 The upper and lower parts of the annular light splitter 4 are mirror-imaged on both sides; in this embodiment, the annular light splitter 4 is mirror-imaged on both sides, so that the light on both sides is uniform and more coordinated.

[0028] See also Figure 2 The annular light splitting part 4 is provided with longitudinal stripe grooves 5 on the surface, and the stripe grooves 5 on both sides are mirror-set; in this embodiment, through the longitudinal stripe grooves 5, the light split by the annular light splitting part 4 can be split into different light through the stripe grooves 5. Based on the Fresnel lens principle, each groove forms an independent small lens, and these small lenses can adjust the light into parallel light or focusing according to the needs. This design based on the Fresnel lens forms different vertical light bands on both sides in layers, thereby increasing the field of view on both sides, and the light is uniform.

[0029] See also Figure 3-Figure 5 The lens body 1 is provided with an inclined slope 6 on the rear side; in the present embodiment, the light emitted by the lens body 1 does not directly enter the convex lens 2, the annular mirror ring 3, and the annular light splitting part 4. After multiple refractions in the lamp holder, the light will enter the lens body 1 through the slope 6, and then be split from the convex lens 2, the annular mirror ring 3, and the annular light splitting part 4, thereby making full use of the light.

[0030] See also Figure 3-Figure 5 The lens body 1 is provided with three connecting parts 7 on the rear side; in this embodiment, the lens body 1 is conveniently installed in the vehicle lamp through the three connecting parts 7, and the three connecting parts 7 are used to stabilize the position.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
