According to some embodiments of the present utility model, the light incident portion 121 is located at a side of the light guide 12 near the base 11.

Specifically, the light is projected from the side (light-entering portion 121) of the light guide 12 near the base 11 into the light guide 12, and the light passes through the reflecting portion 122, and as the distance between the reflecting portion 122 and the light-entering portion 121 is different, the weaker the reflected light is, and finally, the visual effect that the light intensity gradually weakens from near the light-entering portion 121 to far from the light-entering portion 121 (i.e., from near the base 11 to far from the base 11) is displayed at the light-emitting portion 123.

As shown in fig. 2-3 and fig. 6-7, in some embodiments, the substrate 11 has a first surface 111 and a second surface 112, where the first surface 111 and the second surface 112 are opposite, the first surface 111 and the light emitting portion 123 are located on the same side (the upper side of the light emitting assembly 100 as shown in the drawing), the second surface 112 and the reflecting portion 122 are located on the same side (the lower side of the light emitting assembly 100 as shown in the drawing), and the light incident portion 121 is located between the reflecting portion 122 and the second surface 112.

Specifically, the light guide 12 is located at one side of the substrate 11, the plane where the light guide 12 protrudes from the second surface 112 of the substrate 11, and for convenience of description, a portion of the plane where the light guide 12 protrudes from the second surface 112 of the substrate 11 (where L is coplanar with the second surface 112) may be defined as a protrusion 124, and the light incident portion 121 is located at a side of the protrusion 124 facing the second surface 112.

In this way, the light incident on the light guide 12 from the light incident portion 121 propagates along a straight line, and at least a part of the light can be projected onto the reflecting portion 122, so that a softer and gradually changed light emitting effect can be formed at the light emitting portion 123.

According to some embodiments of the present utility model, the included angle between the light incident portion 121 and the reflecting portion 122 is greater than 0 °, i.e. the light incident portion 121 and the reflecting portion 122 cannot be disposed in parallel, so that at least part of the light passing through the light incident portion 121 can be projected to the reflecting portion 122.

As shown in fig. 3 and 4, in some embodiments, the angle α between the light incident portion 121 and the reflecting portion 122 is greater than 90 °. By limiting the included angle alpha between the light incident portion 121 and the reflecting portion 122 to be larger than 90 degrees, on the basis that at least part of light rays of the light incident portion 121 can be projected to the reflecting portion 122, the light guide 12 can be provided with a certain demoulding angle, the demoulding difficulty of the light guide 12 is reduced, and if structures such as patterns or marks are arranged on the back of the light guide 12, the patterns or marks can be prevented from falling off in the demoulding process.

In some embodiments, the light-entering portion 121 is a light-emitting portion.

That is, the light emitted from the light emitting portion is directly projected into the light guide 12, and the light projected to the reflecting portion 122 is reflected by the reflecting portion 122 and is emitted from the light emitting portion 123, and as the distance between the reflecting portion 122 and the light incident portion 121 increases, the light reflected by the reflecting portion 122 becomes weaker, and finally, the visual effect that the light intensity becomes weaker gradually from the position close to the light incident portion 121 to the position far from the light incident portion 121 is exhibited at the light emitting portion 123.
