Optionally, a light holder 40 is coupled to the underlying light source. In this way, the optical component 20 and the position of the underlying light source can be kept corresponding, and a background with a certain display effect is provided for the icons on the display panel 30. Optionally, a hollowed-out area is provided in the caulking groove 41. Thus, the light emitted from the bottom light source can be irradiated onto the optical component 20 through the hollow area. Optionally, the depth of the nest 41 is greater than the thickness of the optical component 20. Thus, the caulking groove 41 can provide a certain protection effect to the optical component 20, and reduce the possibility of abrasion of the optical component 20.

In some embodiments, shown in conjunction with fig. 1, the corners of optical component 20 are obtuse, and the indentations 41 match the shape of optical component 20. The optical component 20 with the edges and the caulking groove 41 can prevent the optical component 20 from rotating in the caulking groove 41, the corners of the optical component 20 are obtuse angles, and abrasion to the corners of the optical component 20 can be reduced in the caulking groove 41. Alternatively, the optical member 20 is an octagon formed by cutting out four corners of a rectangle. Thus, the optical member 20 has a large area as much as possible, and is prevented from rotating and being worn in the insertion groove 41. Alternatively, the insertion groove 41 is rectangular, and elastic pads having a triangular or isosceles trapezoidal cross section are provided at four corners, so that the insertion groove 41 forms an octagonal shape suitable for the optical member 20. Thus, when the optical component 20 is inserted into the insertion groove 41, the elastic member can increase the friction force between the optical component 20 and the lamp holder 40 to prevent the optical component 20 from rotating, and the elastic contact surface of the elastic gasket can prevent the optical component 20 from being in hard contact with the elastic contact surface, thereby preventing the corners of the optical component 20 from being worn.

Thus, a certain display atmosphere can be formed, and the display effect of the icons can be enhanced.

Optionally, the annular area provided with the first structure 22 covers the third hollowed-out portion 43. Thus, after the light passes through the third hollow portion 43, the first structure 22 can scatter the light. Optionally, a fourth hollow portion is further disposed at the periphery of the third hollow portion 43. Part of the light of the bottom light source passes through the fourth hollow portion to form an irregular background area on the display panel 30, so as to enhance the display effect of the icon. Optionally, the area of the fourth hollow portion is smaller than that of the third hollow portion 43. The light of the fourth hollow-out part can be used as a dotted line to form a irregularly-shaped background area.
