Description
Technical field
The utility model relates to a kind of guiding device, is specifically related to a kind of leaded light post.
Background technology
The leaded light post be exactly with light with the loss of minimum from a light sources transmit to the device apart from another point of this light source certain distance.Light is to rely on total internal reflection in leaded light post internal transmission.
The leaded light post generally comprises the light input end that receives incident ray, and the light output end of output light.The light input end generally comprises the plane of incidence, and light output end generally comprises exit facet.The leaded light post also comprises the reflecting surface for internal transmission light.
Incident light enters the leaded light post by the plane of incidence, generally can reflect.Particularly for focused beam, each light in the light beam is in the incident angle difference of the plane of incidence, and light beam can complicated refraction take place at the plane of incidence when entering the leaded light post, be unfavorable for the propagation of light in the leaded light post.When serious, even some light can form total reflection at the plane of incidence in the light beam, can't enter the leaded light post, thereby loses the entrained information of this part light and energy.
And when the leaded light post was used for transmission white light (particularly sunshine), because white light (sunshine) is made up of multiple monochromatic light, even various monochromatic light is identical in the incident angle of the plane of incidence, but the refraction angle generally can be different, can cause chromatic dispersion; When serious, even some monochromatic light can form total reflection at the plane of incidence, can't enter the leaded light post, thereby lose the entrained information of this monochromatic light and energy.
The utility model content
The purpose of this utility model is to provide a kind of leaded light post, it can prevent or reduce focused beam and at the plane of incidence of leaded light post complicated refraction take place, and then make the complete leaded light post that enters of focused beam, prevent that some light is lost by total reflection at the light input end of leaded light post in the focused beam, guarantee that entrained information and the energy of focused beam can effectively enter the leaded light post, and effectively conduction in the leaded light post.
For achieving the above object, the technical solution of the utility model is a kind of leaded light post of design, comprises the first leaded light piece and the second leaded light piece with identical refractive index;
The first leaded light piece, its geometric configuration are the part between cross section and bottom surface of being positioned at that stays after a positive rectangular pyramid is cut by first plane, and this bottom surface is positive rectangular pyramid bottom surface; Described first plane is parallel with one side of bottom surface, and the angle of first plane and bottom surface is the 35-55 degree; Described kernel of section to the distance of bottom surface be the bottom surface length of side 3-15 doubly; Each side of described positive rectangular pyramid and the angle of bottom surface are more than or equal to 89 degree;
Described cross section comprises first limit, the cross section parallel with the bottom surface and second limit, cross section, and the distance of first limit, cross section to bottom surface is bigger to the distance of bottom surface than second limit, cross section;
Described positive rectangular pyramid comprises four sides: comprises first side on first limit, cross section, comprises second side on second limit, cross section, and the 3rd side and the 4th side;
The second leaded light piece, its solid are enclosed by following five bread and form: described cross section, second plane, the face of cylinder, plane, place, the 3rd side, and plane, place, the 4th side; Described second plane is vertical with described cross section, and comprises first limit, cross section; The described face of cylinder is axis with the intersection on second plane and the 3rd plane, and the face of cylinder comprises second limit, cross section; Described the 3rd plane is perpendicular to the bottom surface, and comprises positive rectangular pyramid summit and bottom center, and parallel with first limit, cross section;
