Abstract
The utility model provides a light collecting device, which comprises an optical plate used for collecting light from a light source and provided with a non-planar incident plane and a reflection plane arranged oppositely relative to the incident plane. Light from a light source shines on the incident plane and a total reflection of the light from the light source is formed between the incident plane and the reflection plane. A reflection layer arranged between the incident plane and the reflection plane is used for transmitting the light from the light source in the optical plate. Then after the total reflection, the light from the incident light source is shot out of the optical plate through the reflection layer below. Thus, the light from the light source is centralized and reflected to a photoelectric converter.

In addition, No. 201023379 publication of Chinese T W discloses blooming piece and changes the angle that light is incident to the optics clapboard; The light-source collecting module that makes light in the optics clapboard, produce total reflection and transmit, its opto-electronic conversion wafer place optics clapboard below, make the reflection of light source be perpendicular to light entrance face; So be implemented on product; Must below product, offer slotted eye, so that the light source ejaculation, so will influence the aesthetic property and the applicability of product.
Therefore, the utility model provides a kind of light collecting device in order to improve above-mentioned shortcoming.
Summary of the invention
The purpose of the utility model is to provide a kind of light collecting device, and its plane of incidence and reflection horizon between the reflecting surface that utilizes optical sheet is as the reflection angle that changes light source, to reach the adaptability of product.
For realizing above-mentioned purpose, the utility model discloses a kind of light collecting device, it is characterized in that including:
One collects the optical sheet of light source, thereby this optical sheet has a nonplanar plane of incidence and an opposite reflecting surface that is provided with is injected in the plane of incidence so that this light source produces total reflection between this plane of incidence and this reflecting surface by light source;
One reflection horizon is arranged between this plane of incidence and this reflecting surface so that this light source transmits in optical sheet and penetrate this light source is parallel to this reflecting surface direction by this reflection horizon.
Wherein, this reflecting surface is adjacent to this reflection horizon and is provided with a photoelectric commutator and is incident upon so that this light source to be provided.
Wherein, this plane of incidence is made up of several triangular structure bodies.
Wherein, this plane of incidence has metal coating.
Wherein, be formed with an angle and an outer angle in one between this reflection horizon and this plane of incidence, angle is greater than this outer angle in this.
