An optical coupler which is arranged at a focus position of the Fresnel lens and connected with a light guide fiber can couple light at the focus of the Fresnel lens into the light guide fiber. The light guide fiber is connected with a diffuser arranged at a place in need of illumination. The device has the advantages that the solar conversion efficiency is high, the device is environment-friendly and energy-saving, the cost is low, and the applicability is good.
Description
Technical field
The present invention relates to a kind of natural lighting device.
Background technology
Running car enters behind the tunnel unexpected dark a slice on sunny highway, a large amount of lightings need be arranged; Building is outer sunny, and underground parking garage but is long-term darkness, the illumination of therefore having to turn on light.Illumination is that indispensable energy utilizes engineering in the human daily life.Since the Edison invented electric light, illumination just is associated together with electric energy, although the power saving fluorescent lamp that adopts at present, led illuminating lamp etc. can greatly reduce the consumption to electric energy, eventually still can expend a large amount of electric energy.Energy-saving and emission-reduction be present every country all in the earth environmental objective of vigorously advocating, be humanly to utilize measure for reducing the important energy that carbon emission takes and utilize luminous energy in the solar energy and heat energy.The photovoltaic effect of human use's semi-conducting material is carried out solar electrical energy generation, although can reduce the carbon emission that the heat generating brings, but there are two large main disadvantages in photovoltaic generation: at first, semiconductor silicon material can produce a large amount of pollutions in the process of the wafer that is processed into photovoltaic generation, thereby causes the destruction to earth environment; Secondly, the photovoltaic generation utilization only be the luminous energy part of sunshine, heat energy a large amount of in the solar energy not only can not be converted to electric energy, the high temperature that causes can reduce the photoelectric transformation efficiency of photovoltaic material on the contrary, so that the energy conversion efficiency of photovoltaic generation becomes lower.And electric energy is when being used for illumination, and bulb also can produce thermal conductance and cause and wasted a large amount of energy except luminous.The capacity usage ratio of at present tunnel and garage illumination is very low in a word, and can a large amount of poisonous and harmful substance of bad student in energy conversion process.
Summary of the invention
The present invention will overcome that existing helioplant pollutes greatly in manufacture process, the shortcoming under the energy conversion efficiency, and the optically focused energy-saving light line illuminator of a kind of solar energy conversion efficiency height, environmental protection is provided.
Optically focused energy-saving light line illuminator of the present invention, it is characterized in that: comprising: a solar energy acquisition mechanism that comprises Fresnel Lenses, a luminous energy coupler is arranged on Fresnel Lenses focus place, the luminous energy coupler is connected with light-conductive optic fibre, the luminous energy coupler is coupled in the light-conductive optic fibre Fresnel Lenses focus place, and light-conductive optic fibre connects the diffusing globe that is arranged on the place of need to throwing light on.
Further, described luminous energy coupler is microscopical object lens.
Further, the tracker of following the tracks of the sunray direction is housed in the described solar energy acquisition mechanism, Fresnel Lenses is arranged on the rotating base, and described rotating base is controlled by described tracker.
Perhaps, be equipped with a plurality ofly towards different Fresnel Lenses in the described solar energy acquisition mechanism, so that in sunshine direction transition process, a Fresnel Lenses always arranged towards the sunray direction.
The present invention is thrown light on solar energy behind optically focused by optical fibre transmission, will transform light energy be not electric energy, sunshine directly is directed to dark part throws light on, and really realizes free of contamination environmental protection lighting.
Though the optical fiber diameter is little, its light transmission is good, and optical loss is little, can transmit high-light-energy.With Fresnel Lenses sunshine is converged first outdoor, produce the hot spot of a high energy, the energy (luminous energy and heat energy) on the hot spot is extremely strong at this moment, if this hot spot place puts the extinction object, can cause that then object temperature sharply rises; Luminous energy can be coupled to diameter with microscopical object lens as the luminous energy coupler between hot spot and the Transmission Fibers is in 3 millimeters the light-conductive optic fibre, fiber end face must be transparent bright and clean, otherwise high temperature can damage end face, optical fiber transfers to luminous energy indoor, output at optical fiber arranges the optics means for diverging, be diffusing globe, make luminous energy be used for room lighting.
The lighting device of this innovation can be used for the illumination on tunnel, underground parking garage, elevator, in the shade building, underground square etc., makes easily, and is with low cost, has preferably practicality, if be converted into product, will produce higher economic benefit.
Advantage of the present invention is: solar energy conversion efficiency height, environmental protection and energy saving, cost is low, usability good.
