At this time, the headlamp will play its advantages. Just put the headlamp on the head to complete the lighting. Headlamps are suitable for many occasions, such as outdoor sports, hospitals, etc. The lens is indispensable inside the lamp. Different types of lenses refract light differently, which leads to different lenses suitable for different types of lamps.

The development of a headlight lens with high beam and low beam lighting functions using the same light source saves energy and space, and the bright distribution of the formed light spot is appropriate and the illuminated range is reasonable.

[0004] The headlamp lens has the following problems when in use: the headlamp lens cannot adjust the size of the light spot when in use. Different light spots are required in different usage situations. The headlamp lens does not have the function of adjusting the size of the light spot, resulting in a poor overall headlamp feel.

A part of the light passes through the light incident surface to the reflective surface to generate total reflection, and the totally reflected light is then projected onto the target object through the light exiting surface.

[0011] Preferably, there are several mounting snap-fit ​​buckles, and the mounting snap-fit ​​buckles are sequentially distributed on the edge positions of the light-emitting surface substrate of the device body. By connecting the mounting snap-fit ​​buckles with the external lamp, the lens is assembled with the external lamp to ensure the normal use of the lens.

[0012] Preferably, the accommodating cavity is a concave cylindrical structure cavity, which can converge the light entering the light inlet, facilitate the subsequent light to be better projected through the light emitting surface, and make the use effect of the entire lens better.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model provides Figure 1-4 The adjustable headlamp lens shown includes a device body 1, a mounting snap-fit ​​buckle 3 is fixedly installed at the bottom of the device body 1, and the lens 2 is assembled with the external lamp by connecting the mounting snap-fit ​​buckle 3 with the external lamp. A plurality of lenses 2 are arranged inside the device body 1, and a receiving cavity 8 is arranged inside the lens 2, and a light inlet 5 is reserved at the bottom of the receiving cavity 8. A light emitting surface 6 is arranged on the surface of the device body 1, and an infrared sensor 4 is fixedly installed on the back of the light emitting surface 6. The infrared sensing structure is used to control whether the light is on or off, so as to facilitate the adjustment of the light.

[0025] There are two lenses 2, and the two lenses 2 are arranged in sequence from left to right on the same horizontal line, and a gap is left between the two lenses 2. By setting two lenses 2 with different angles, the light is subsequently controlled by an external circuit board to enter two different lenses 2, thereby controlling the size of the exit light spot, thereby improving the adaptability of the entire lamp.

[0026] The preset angles of the two lenses 2 are different, and the preset angles of the two lenses 2 are 10° and 60° respectively. The light is controlled to enter the lens 2 of 10° or 60° through an external circuit board, so as to control the size of the emergent light spot. The spot sizes of the emergent light are different for lenses 2 with different angles, among which the spot of 10° is the smallest and the spot of 60° is the largest.

[0027] The outer ring of the lens 2 is a reflective surface 7, and the reflective surface 7 is a total reflective surface, and the reflective surface 7 is an arc-shaped smooth surface. A part of the light passes through the light incident surface 9 to the reflective surface 7 to generate total reflection, and the totally reflected light is then projected onto the target object through the light emitting surface 6.

[0028] There are several mounting snap buckles 3, and the mounting snap buckles 3 are sequentially distributed on the edge of the substrate of the light-emitting surface 6 of the device body 1. By connecting the mounting snap buckles 3 with the external lamp, the lens 2 is assembled with the external lamp to ensure the normal use of the lens 2.

[0029] The accommodating cavity 8 is a concave cylindrical structure cavity, which can converge the light entering the light inlet 5, so that the subsequent light can be better projected through the light emitting surface 6, so that the use effect of the entire lens 2 is better.

[0030] A light incident surface 9 is provided inside the accommodating cavity 8, and the light incident surface 9 is an arc-shaped smooth surface. A spherical protrusion 10 is provided on the top of the accommodating cavity 8, and the spherical protrusion 10 has the function of converging light, so that the light entering from the light inlet 5 and the light incident through the top wall of the accommodating cavity 8 are converged and then emitted from the light emitting surface 6, thereby ensuring a better subsequent lighting effect and making the use effect of the entire lens 2 better.

[0031] Working principle: When using the adjustable headlight lens, first, light enters the lens 2 through the light inlet 5, a part of the light passes through the light incident surface 9 to the reflective surface 7 to generate total reflection, and the totally reflected light is then projected onto the target object through the light emitting surface 6, and another part of the light enters from the light inlet 5 and is incident on the top wall of the accommodating cavity 8 and then is emitted from the light emitting surface 6, thereby ensuring a better subsequent lighting effect and making the use effect of the entire lens 2 better;

[0032] By setting two lenses 2 with different angles, the sizes of the subsequent emitted light spots are different. When the light enters the lens 2 with an angle of 10° or 60°, the sizes of the emitted light spots are different, among which the light spot with an angle of 10° is the smallest and the light spot with an angle of 60° is the largest. In this way, the light entering the lens 2 with an angle of 10° or 60° is controlled by an external circuit board, thereby controlling the size of the emitted light spot, so that the user can adjust the size of the light spot according to the actual environment in which he is located, and then adjust the overall lighting work, so that the adaptability of the entire lamp is improved;

[0033] At the same time, the infrared sensor 4 can be used to control the light to turn on or off.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
