Light guiding structure for free lighting patterns

Abstract

The invention provides a light guiding structure for free lighting patterns, and particularly relates to a three-dimensional lighting structure capable of forming patterns freely. The light guiding structure for the free lighting patterns comprises a light guiding body, wherein a light entering surface is arranged in the center of the light guiding body and comprises a first reflecting surface and a second reflecting surface correspondingly; most of light is gathered between the first reflecting surface and the second reflecting surface in a total reflection manner; at least one light existing micro-structure is arranged on the first reflecting surface; the light entering surface is a plane or a recessed surface according to the shape of a surface of a luminous source so that a comprehensive light gathering effect is achieved; and the light exiting micro-structure consists of first reflecting surface projections, first reflecting surface recesses or roughened surfaces, and guides out total reflection light in the light guiding body to obtain lighting patterns. Divergent light can be gathered in an effective light guiding track with the aid of the light entering plane, direct light is totally guided in the light guiding track by the first reflecting surface and the second reflecting surface so that effective light guiding amount is redoubled, the light can be sufficiently used for the light exiting micro-structure, the luminous source can be minimum, the luminous flux can also be minimum, and optical high-luminescence patterns which are uniform gradually can be generated.

Description

technical field [0001] The invention relates to a light guide structure with a free light emission pattern, in particular to a light guide optical structure with a light-emitting source light-splitting effect and a light-emitting pattern. Background technique [0002] Light guide strips have become one of the lighting products that improve recognition and aesthetics. In view of the fact that the existing light sources are illuminated by the end surface, guided by total reflection, and composed of light microstructures, the light output efficiency and uniformity of light emission are poor. In addition, if If it is necessary to emit light to form a geometric figure, it is necessary to arrange a large number of light sources, which will cost a lot of money and affect the overall aesthetics of the lamp. Not only that, but the light shape produced by it will also have uneven highlights. [0003] An overview is provided figure 1 The shown light guide structure is provided with a ...

Problems solved by technology

[0005] For this reason, the object of the present invention is to solve the problem of the existing light guide strip, whose light incident surface is flat, which will cause part of the light to overflow, which will cause a difference in brightness and light source intensity, resulting in energy consumption, and the appearance of the light guide strip. The shape can only be straight or arc-shaped. If it is arranged as a multi-layered geometric figure, it will cost a lot of money, the light shape is not continuous, the overall light shape is uneven in brightness, and it will affect the visual beauty of the overall light shape.
