Embodiment Construction

[0013] Please also refer to figure 1 and figure 2 , is a schematic plan view and a schematic perspective view of the first embodiment of the light guide device of the present invention. The light guiding device 1 is an elliptical annular structure, which includes a top surface 12 , a bottom surface 13 opposite to the top surface 12 , an inner surface 11 and an outer surface 10 opposite to the inner surface 11 . The outer surface 10 is provided with a plurality of grooves 14, the grooves 14 are light incident surfaces, and the inner surface 11 is a light exit surface.

[0014] The light is incident from the groove 14 and transmitted through the annular structure of the light guide device, and then exits from the annular inner surface 11, so that the outgoing light is more uniform. Wherein, the groove 14 and the inner surface 11 can be subjected to surface treatment, such as sandblasting and atomization treatment, so that the light can be scattered and evenly injected into th...

Abstract

The invention is a guide device, which is annular structure; it includes a top surface, a bottom surface relative to the top surface, an inner side surface and an external surface correspondent to the internal one. Parts of the external surface or the whole surface are the light incidence surface; the internal side surface is the emergent face.

Description

【Technical field】 [0001] The invention relates to a light guide device and a luminous marker, in particular to a light guide device and a luminous marker applied to automobiles. 【Background technique】 [0002] There is usually a logo on the car, and the logo usually includes the brand promotion pattern of the company that produces the car. The pattern not only has an aesthetic effect, but also plays an advertising role. It works in bright light, but its publicity effect is limited in dark light. Therefore, the sign is usually equipped with a light source, such as a light emitting diode (Light Emitting Diode, LED), and the light emitted by the light emitting diode passes through a The plate-shaped light guide device made of transparent or translucent material is then irradiated onto the promotional pattern. However, the light emitted by the light-emitting diode is limited by the point light source itself, and its beam is concentrated in the range of the maximum emission angl...
