Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0025] The present invention provides an inner lampshade and a position lamp for improving the uniformity of position lamps. The following provides a plurality of embodiments to describe in detail the inner lampshade and the position lamp for improving the uniformity of position lamps provided by the present invention.

[0026] Example 1

[0027] The inner lampshade provided by this embodiment improves the uniformity of the position lamp, such as Figure 2 As shown, it includes a light emitting end face 1; the light emitting end face 1 includes a plurality of curved surfaces 11, the plurality of curved surfaces 11 are arranged in a matrix, and adjacent curved surfaces 11 are connected to each other.

[0028] The light emitting end surface 1 is composed of multiple curved surfaces 11. The curved surfaces 11 can effectively refract light, increase the refraction angle of the light emitting end surface 1, and make the light at the light emitting end surface 1 diverge toward the outside of the light emitting end surface 1, thereby reducing the brightness and heat at the center of the light emitting end surface 1 and improving the lighting uniformity.

[0029] The outer contour of the light emitting end face 1 is roughly a parabola, which is composed of a plurality of curved surfaces 11 arranged in a matrix. The appearance of the plurality of curved surfaces 11 arranged in a matrix resembles a plurality of corn kernels arranged together.

[0030] The curved surface 11 may be a spherical curved surface 11 or an ellipsoidal curved surface 11 or any other suitable shape.

[0031] The spherical curved surface 11 is a portion of the spherical surface, and the ellipsoidal curved surface 11 is a portion of the ellipsoidal surface.

[0032] Adjacent curved surfaces 11 are connected to each other, and the connections between the adjacent curved surfaces 11 can be smoothly transitioned, making the light emitting end surface 1 smoother as a whole, which is beneficial to increasing the refraction angle of the light emitting end surface 1 .

[0033] The shapes of the multiple curved surfaces 11 may be the same or different.

[0034] When the shapes of the multiple curved surfaces 11 are the same, it is easy to process and manufacture. During processing, the light-emitting end surface 1 can be first processed into a parabola, and then the corn kernel pattern is processed on the parabola to obtain the light-emitting end surface 1 provided in this embodiment.

[0035] Furthermore, the inner lampshade for improving the uniformity of the position light further includes a light incident end surface 2 and a first parabola 3 ; the light incident end surface 2 is arranged outside the first parabola 3 , and the light incident end surface 2 is connected to the first parabola 3 .

The specific structure of the light incident end surface 2 and the first parabola 3 is consistent with the existing technology and will not be repeated here.

[0037] The light incident end surface 2 and the first parabola 3 are both arranged opposite to the light emitting end surface 1. A portion of the light source 5 is reflected by the light incident end surface 2 to the first parabola 3, and the light reflected to the first parabola 3 is refracted by the first parabola 3. The light refracted by the first parabola 3 is refracted at the light emitting end surface 1; another portion of the light source 5 is refracted at the light incident end surface 2, and the light refracted by the light incident end surface 2 is refracted at the light emitting end surface 1.

[0040] The light emitting end surface 1 is composed of multiple curved surfaces 11. The curved surfaces 11 can effectively refract light, increase the refraction angle of the light emitting end surface 1, and make the light at the light emitting end surface 1 diverge toward the outside of the light emitting end surface 1, thereby reducing the brightness and heat at the center of the light emitting end surface 1 and improving the lighting uniformity.

[0041] Furthermore, the position light further includes a circuit board 4, which is arranged opposite to the inner lampshade that improves the uniformity of the position light, and the circuit board 4 and the inner lampshade that improves the uniformity of the position light are arranged at intervals.

[0042] Furthermore, the position lamp further comprises a light source 5, which is arranged opposite to the inner lampshade for improving the uniformity of the position lamp, and the light source 5 is spaced apart from the inner lampshade for improving the uniformity of the position lamp.

[0043] A portion of the light source 5 is reflected by the light incident end surface 2 to the first parabola 3, and the light reflected by the first parabola 3 is refracted by the first parabola 3. The light refracted by the first parabola 3 is refracted at the light emitting end surface 1; another portion of the light source 5 is refracted by the light incident end surface 2, and the light refracted by the light incident end surface 2 is refracted at the light emitting end surface 1.

[0044] Furthermore, the light source 5 is arranged on the circuit board 4 .

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
