Abstract

Disclosed is a light-collecting device which is characterized in that the light-collecting device is a Fresnel lens or a reflection mirror. A plurality of beams of light-guide fibers are installed at one side of the device. When an incident-light angle changes, the focal point of the Fresnel lens or the reflection mirror moves at the other side. Incident ends of the light-guide fibers are all located on a focal-point changing path. Light captured through the light-guide fibers is converged through the light-guide fibers, every three of which are converged into one group so as to be in connection with a next group of single light-guide fiber until the light-guide fibers are converged into one light-guide fiber and at last, the light-guide fiber can be externally connected with a device for use. Every three light-guide fibers are converged into one group so as to be in connection with the next group of single light-guide fiber through an optical joint. When the Fresnel lens is used, the light and the light-guide fibers are located at the two sides of the Fresnel lens and when the reflection mirror is used, the light and the light-guide fibers are located at the same side of the reflection mirror.

Description

Light collection device

Technical field

A kind of light collection device for different incidence angles degree light is concentrated and conducted.

Background technology

Mainly the lighting system that adopts Fresnel Lenses and light transmitting fiber composition for the device of leaded light at present, its defect is in the time that light angle changes, need that Fresnel Lenses is servo-actuated together with light transmitting fiber can reach daylighting effect, that its servo control mechanism requires is accurate, cost is high, maintenance is complicated; And the another kind of device that is used for light harvesting is the mode that has adopted fresnel lens array, the focus of each Fresnel Lenses has a light transmitting fiber, although there is no servo control mechanism, light harvesting effect is pulsed, and is not continuous.

Summary of the invention

The present invention is in order to solve traditional pipeline gathering-device cost and a kind of light collection device of daylighting continuity problem, it is characterized in that: Fresnel Lenses or catoptron wherein a kind of, one side is equipped with by some bundle light transmitting fibers, in the time that angle of incident light changes, the focus of Fresnel Lenses or catoptron is in a side shifting, fibre-optic incident end is all positioned on the path of focal variation, the light of catching via light transmitting fiber more every three converge that next organizes single light transmitting fiber for a group of access, become a light transmitting fiber until converge, this last root light transmitting fiber can utilize by external equipment, it is that one group and next are organized between single light transmitting fiber and be connected by optic splice that every three light transmitting fibers converge, while using Fresnel Lenses, the both sides of light and light transmitting fiber separation Fresnel Lenses, while using catoptron, light and light transmitting fiber are positioned at the homonymy of catoptron, it can be the one in line, face that the path of described focal variation forms, described light transmitting fiber three beams converges carries out next stage, for not enough three beams, group under single bundle access interval.

Adopt this light collection device, while variation due to light incident, focus changes in a side of Fresnel Lenses or catoptron thereupon, on the path of focal variation, ensure to have the covering of light transmitting fiber incident end, therefore can ensure the continuity of ray-collecting, and Fresnel Lenses does not have servo control mechanism, reduce cost.

Brief description of the drawings

Fig. 1 is while using catoptron, a kind of exemplary configurations form of light collection device.

Fig. 2 is while using Fresnel Lenses, a kind of exemplary configurations form of light mobile device.

Shown in Fig. 1,1.-1st, catoptron, is 2. optic splice, is 3. light transmitting fiber, in figure, arrow direction is light incident direction, can see that while using catoptron, incident ray and light transmitting fiber are positioned at the homonymy of catoptron.

Shown in Fig. 2,1.-2nd, Fresnel Lenses, is 2. optic splice, is 3. light transmitting fiber, in figure, direction is light incident direction, can see and using when Fresnel Lenses, how the both sides of light and light transmitting fiber separation Fresnel Lenses.

Embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is set forth.

Fresnel Lenses 1.-2 or catoptron 1.-1 wherein a kind of, by some bundle light transmitting fibers 3. one side is equipped with, in the time that angle of incident light changes, the focus of Fresnel Lenses 1.-2 or catoptron 1.-1 is in a side shifting, light transmitting fiber incident end 3. is all positioned on the path of focal variation, the light of 3. catching via light transmitting fiber more every three converge that 3. next organize single light transmitting fiber for a group of access, become a light transmitting fiber 3. until converge, 3. this last root light transmitting fiber can utilize by external equipment, 3. every three light transmitting fibers converge is that one group and next are organized single light transmitting fiber and be 2. connected by optic splice between 3., use Fresnel Lenses 1.-2 o'clock, 3. the live apart both sides of Fresnel Lenses 1.-2 of light and light transmitting fiber, use 1.-1 o'clock light of catoptron and light transmitting fiber to be 3. positioned at the homonymy of catoptron 1.-1, it can be the one in line, face that the path of described focal variation forms, described light transmitting fiber 3. three beams converges and carries out next stage, for not enough three beams, group under single bundle access interval.
