[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.
[0028] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.
[0029] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0030] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0031] The utility model provides an optical structure, which includes a light guide surface and a light emitting surface. The light guide surface is arranged opposite to the light emitting surface, and the light guide surface and the light emitting surface are connected by a side wall, and the side wall is provided with a pattern structure, and in the cross section of the optical structure, the height of the light guide surface is less than the height of the light emitting surface. The reflection of light is achieved by the pattern structure of the side wall of the special-shaped light guide, so that the optical luminescence requirements of the special-shaped light guide can be met, the uniformity of the light guide can be improved, the optical luminescence requirements can be met, and the lighting effect of the light guide can be optimized.
[0032] See below Figures 1 to 3 , Figure 1 is a schematic diagram of a light guide reflection principle of an embodiment; Figure 2 yes Figure 1 Total reflection diagram of light ray P on surface b; Figure 3 yes Figure 1 Light path diagram of the light ray in the light guide.
[0033] The incident light is reflected by the light guide surface a (for example, a light guide tooth may be provided) to form a light P which is totally reflected on the side wall (reflection surface b) and finally emitted from the light emitting surface c. Figure 1 As shown. The condition for total reflection of surface b can be achieved when the angle between light P and surface b is greater than the critical angle for total reflection. The critical angle is related to the material of the light guide. Commonly used materials are transparent PC or PMMA. The critical angle of PC is 129° (90°+39°) and the critical angle of PMMA is 132° (90°+42°).
[0034] By adjusting the ratio of size A to size B, the angle between the light and surface b can be made larger than the critical angle for total reflection, so that the light can be emitted horizontally from the luminous surface. When the ratio of A:B is 1:2.1 to 1:2.7 (the angle between the light P and surface b is 131° to 157°), the angle between the light P and surface b is larger than the critical angle for total reflection, and the light P is totally reflected on surface b (such as Figure 2 shown).
