Abstract
An optic device of sunlight illumination of a tunnel south exit comprises a parabolic column curved surface light adjusting lens, a parabolic column curved surface light collecting lens, a light emitting groove, a secondary light guiding lens, a flat face reflecting mirror set, and a primary light guiding lens. A condenser is formed by the parabolic column curved surface light collecting lens which faces toward the sun, and the parabolic column curved surface light adjusting lens which is provided with a same focal point with the parabolic column curved surface light collecting lens. After passing through the parabolic column curved surface light collecting lens to be collected and then passing through the parabolic column curved surface light adjusting lens to enable a light path to be adjusted, parallel sunlight becomes parallel light again to be emitted from the light emitting groove of parabolic column curved surface light collecting lens to the primary light guiding lens, and then the primary light guiding lens enables the parallel light to be reflected to the secondary light guiding lens, a reflecting light ray is the same with a tunnel in the direction and the secondary light guiding lens is installed outside the tunnel south exit. The slant flat face reflecting mirror set is installed inside the light path, in which the top portion of the tunnel is placed, of the secondary light guiding lens and enables the sunlight to be transmitted to road surfaces everywhere in a zone of the tunnel south exit. The optic device of the sunlight illumination of the tunnel south exit is simple in structure and has wide application prospects.
Description
Technical field
The utility model relates to the sun light lighting field, relates in particular to the Optical devices of the sun light lighting of a kind of tunnel South Exit.
Background technology
For vcehicular tunnel, except day and night lighting System Assurance base lighting brightness requirement must be installed, also have very large characteristics, the brightness step (brightness rate of change) that is exactly (being called for short luminance transition interval) in driver's special requirement tunnel import and export one segment distance must limit within the specific limits, otherwise " black hole " and " white hole " phenomenon will occur and cause the accident, namely at this important be also in the most dangerous section brightness (than outside environment brightness) be one than the relative value of outside environment brightness but not absolute value; In case adapted to the variation of lamplight brightness through driver behind this luminance transition interval, the eyesight of driver's eyes has been recovered also just not had the problems referred to above after normal.For example the driver from the highway of sunshine at noon very strong (as 60000Lx) in case enter at a relatively high speed in (light weak (200Lx)) tunnel in the very short time of (200Lx), because the brightness variable gradient is too large, tend to cause that driver's spinning sensation loses eyesight even at short notice and has an accident.And overcast and rainy, namely when tunnel outside light more weak (as 5000Lx), for identical or lower tunnel intraoral illumination brightness, there are not the problems referred to above in the driver.The extreme phenomenon of this situation---night particularly, for the driver, the relative tunnel internal illumination of the brightness outside the tunnel on highway is for the driver, or even enters Liang Chu from the light dark place, just has the problem that is not suitable with.According to " highway tunnel ventilation Lighting Design standard " (JTJ026.1-1999) technical standard about the brightness designing requirement between transition region in present tunnel illuminating system, generally the tunnel is imported and exported and be divided into four sections such as inlet region, transition region, mesozone and outlet area, and require to change according to the brightness (sunlight intensity) of outside, tunnel in the turnover mouth region and the intensity of automatically regulating lighting source, to reach the target of saving the energy.But because the automatic control system working environment is too poor etc. former thereby cause fault rate high, its system maintenance maintenance has again very large difficulty, so in Practical Project, major part still adopts the constant brightness illumination scheme: namely the brightness step value in tunnel transition district must be less than the brightness step limit under noon in summer the strongest solar light irradiation, this limit data is obviously to (three seasons beyond summer a little less than illumination, particularly) winter, overcast and rainy and evening, just exist the energy waste phenomenon at the interval lighting source of luminance transition.
Summary of the invention
For the problem that prior art exists, the utility model provide a kind of simple in structure, the sunshine utilization ratio is high and the Optical devices of the sun light lighting of high reliability, a kind of tunnel South Exit of reducing costs.

Described parabolic cylinder solar concentrator lens with curved surface 2 is coated with reflectance coating.
Speculum in described plane mirror group 6 is installed on respectively between the base lighting lamp.
A described leaded light mirror 7 is arranged on the both sides of tunnel 5 South Exits.
Also be provided with buffer unit on highway in the outside certain distance in South Exit place, described tunnel, leaded light mirror 7 and secondary light conduction mirror 4 that concentrator and concentrator are corresponding are arranged on buffer unit.
After adopting and first converge sunshine and adjust light path, the utility model directly passes in and out from the irradiation of tunnel top straight line with the parallel sunshine of high brightness, reflex to respectively again the mode on road surface, therefore utilization simple in structure, as effectively to realize the sunshine high-efficiency and low-cost has broad application prospects.
