Embodiment Construction

[0023] FIG. 1 is a schematic structural diagram of a light guide device according to an embodiment of the present invention, and FIG. 2 is an exploded view of FIG. 1 . Referring to FIG. 1 and FIG. 2 , the light guide device 100 can be used to display a light signal 210 provided by a light source 200 , such as light and shade, color or a combination thereof. The light guide device 100 includes a light guide column 110 , a light diffusion unit 120 , a first reflective material layer 130 and a second reflective material layer 140 . In this embodiment, the light source 200 is, for example, an LED package structure or an LED chip. Furthermore, the light guide column 110 and the light diffusion unit 120 are made of, for example, polymethyl methacrylate, polycarbonate or other transparent light guide materials, while the first reflective material layer 130 and the second reflective material layer 140 are, for example, Made of silver, mercury or other reflective material.

Abstract

The invention discloses a light guiding device, comprising a light pipe which is provided with a first light incidence surface and a first light extraction surface, a second light incidence surface which is adjacent to the first light extraction surface, a second light extraction surface, a photodiffusion unit of a first reflecting surface and a second reflecting surface, a first reflecting material layer which is deployed on the first reflecting surface and a second reflecting material layer which is deployed on the second reflecting surface. The area of the second light extraction surface is larger than that of the first light extraction surface. An optical signal provided by a light source is applicable to getting through the first light incidence surface, the first light extraction surface and the second light incidence surface, and is also applicable to being reflected by the second reflecting surface and the first reflecting surface to exit from the second light extraction surface.

Description

technical field [0001] The present invention relates to a light guiding device, and more particularly to a light guiding device for displaying a light signal provided by a light source. Background technique [0002] With the advancement of technology, electronic devices have become inseparable from human's daily life. Generally speaking, electronic devices all have display lights, and the current display lights usually use light emitting diodes (light emitting diodes, LEDs) as light sources, and use a light guide device to transmit the light signals provided by the light emitting diodes to the housing. Body (case) surface. [0003] For example, a circuit board, a light emitting diode, and a light guide device are usually disposed in a carrier for accommodating a portable hard disc device (HDD). The light emitting diode is arranged on the circuit board to provide a light signal, and the light guide device is arranged between the light emitting diode and the panel of the ext...
