Background technology
Along with economic fast development, Electricity Demand surpasses 20% speed increment with every year, and according to present economic trend and Chinese Resources situation, after 2010, there is pressure in supply of electric power.And developing rapidly along with the highway in China traffic, vcehicular tunnel also increases increasingly, national regulation, length surpasses the vcehicular tunnel of 400m must install illuminator, at present, be applied to tunnel illumination maximum be to adopt high pressure Xe lamp, perhaps other light fixture such as LED lamp, because much the tunnels physical features is complicated, mileage is relatively long, very high to electricity consumption requirement and lamp life, therefore utilizing solar energy is a kind of very effective method for tunnel illumination.That solar energy has is safe and reliable, long service life, do not need fuel, the advantage such as free from environmental pollution.
Summary of the invention
The shortcoming that exists in order to overcome above-mentioned prior art, the object of the present invention is to provide the optical system of the sun light lighting of a kind of novel east-west direction tunnel face, native system directly utilizes sunshine to carry out the system of tunnel illumination, need not to become electric energy to use light energy conversion, energy utilization efficiency is higher like this, thereby the reduction construction costs is saved electric power resource.
In order to achieve the above object, the present invention adopts following technical scheme:
The optical system of the sun light lighting of a kind of novel east-west direction tunnel face, comprise sun tracker 1, speculum 2 on sun tracker 1 is installed, be arranged on the local lens 4 with speculum 2 coaxial confocals, lens 4 are connected with speculum 2, sun tracker 1, be fixed on the reflecting plate 5 of lens 4 emergent light line ends, be arranged on the light pipe 6 on tunnel inner wall 10, be arranged on the half-reflecting half mirror 7 on light pipe 6, be arranged on scatterer 8 and the completely reflecting mirror 9 of half-reflecting half mirror 7 belows, the light of half-reflecting half mirror 7 reflections is through scatterer 8 outgoing.
Described speculum 2 be a parabolic shape, in be coated with the speculum of high inverse medium.
Described lens 4 adopt Fresnel Lenses, speculum 2, and lens 4, sun tracker 1 use rigid mount is fixed.
Described sun tracker 1 is comprised of a 4 quadrant detector and stepper motor, guarantees that speculum 2 is all the time towards the sun.
Half-reflecting half mirror 7 is comprised of a plurality of half-reflecting half mirrors and a completely reflecting mirror.
Place, East and West direction gateway, tunnel face respectively settles a cover sunshine receiving system, the illumination of each device charge tunnel one half-distance.
Adopt optical module that sunshine is directly introduced tunnel illumination, the illumination of porch, two ends is stronger, successively in the middle of the tunnel, light intensity constantly weakens, and meets the tunnel illumination requirement, and method is simple, need not is that electric energy uses again with light energy conversion, has improved like this capacity usage ratio.

The specific embodiment
As shown in Figure 1, the optical system of the sun light lighting of a kind of novel east-west direction tunnel face, comprise sun tracker 1, speculum 2 on sun tracker 1 is installed, be arranged on the local lens 4 with speculum 2 coaxial confocals, lens 4 are connected with speculum 2, sun tracker 1, be fixed on the reflecting plate 5 of lens 4 emergent light line ends, be arranged on the light pipe 6 on tunnel inner wall 10, be arranged on the half-reflecting half mirror 7 on light pipe 6, be arranged on scatterer 8 and the completely reflecting mirror 9 of half-reflecting half mirror 7 belows, the light of half-reflecting half mirror 7 reflections is through scatterer 8 outgoing.
Described speculum 2 be a parabolic shape, in be coated with the speculum of high inverse medium; Described lens 4 adopt Fresnel Lenses, speculum 2, and lens 4, sun tracker 1 use rigid mount is fixed;
Described sun tracker 1 is comprised of a 4 quadrant detector and stepper motor, guarantees that speculum 2 all the time towards the sun, makes collection efficiency the highest, and lens 4 rotate with sun tracker 1, with the light of speculum 2 collections with the collimated light beam outgoing.
Half-reflecting half mirror 7 is comprised of a plurality of half-reflecting half mirrors and a completely reflecting mirror, half-reflecting half mirror 7 will be through the light beam of light pipe 6 conduction incidents, a part arrives scatterer 8 through reflection, pass through again scatterer 8 uniformly divergence of beam in the tunnel, another part light is transferred to next stage half-reflecting half mirror 7 through transmission, until be transferred to the completely reflecting mirror 9 of afterbody, completely reflecting mirror all reflects light, then pass through scatterer with light scattering in the tunnel.
Place, East and West direction gateway, tunnel face respectively settles a cover sunshine receiving system, the illumination of each device charge tunnel one half-distance.
In system, place, east-west direction gateway all is equipped with the sunshine receiving system, and thing both sides device is identical, the illumination of each charge tunnel one half-distance.In system, speculum is fixed on sun tracker 1, lens 4 use rigid mounts are connected with speculum 2, and be fixed on the place with speculum 2 coaxial confocals, sun tracker 1 is comprised of a 4 quadrant detector and stepper motor, guarantee that speculum all the time towards the sun, makes collection efficiency the highest.Reflecting plate 2 maintains static, the light beam of diverse location lens 4 outgoing is focused on the porch of light pipe 6, light pipe 6 is fixed along the tunnel direction, light arrives half-reflecting half mirror 7 in inside through Multi reflection, half-reflecting half mirror 7 is arranged on light pipe 6, and each half-reflecting half mirror 7 and completely reflecting mirror 9 bottoms are equipped with scatterer 8.When light arrives half-reflecting half mirror 7 minute surfaces through light pipe 6 internal reflections, part light arrives scatterer 8 through reflection, thereby be radiated at uniformly light in the tunnel through scatterer 8, another part light is through the conduction of transmission and light pipe 6, conduct to next stage successively along the tunnel direction, until last completely reflecting mirror 9, the light of incident is all reflected, be radiated in the tunnel.
It is changeover portion that tunnel illumination requires tunnel portal and outlet short distance, and brightness is high herein, and tunnel zone line brightness is slightly low, can avoid like this porch uncomfortable because of the suddenly dimmed human eye that brings.Adopt the half-reflecting half mirror group more to meet the tunnel illumination feature, at the tunnel portal place, the light beam light intensity is larger, the luminous flux that sends through half-reflecting half mirror and scatterer is large, light beam is through the transmission of optical system (light pipe, half-reflecting half mirror group), light decay is serious, and total light flux constantly descends, and adopts completely reflecting mirror that light is all reflected until be transferred to afterbody.
