Description
Technical field
The present invention relates to optical element, system or instrument fields, in particular to a kind of light collection system.
Background technique
Since tunnel portal section is the intersection of the closed dark space of tunnel internal and external bright space, inside and outside tunnel
Huge luminance difference generates huge vision light and shade mutation, forms daytime and night into hole when driver being caused to enter tunnel
When " black-hole effect " and " white hole effect ", easily initiation traffic safety accident.Therefore, the illumination of road tunnel entrance section is extremely
Important, the illumination index of illumination is extremely harsh, should consider the factors such as structure size, the design speed in tunnel, also to meet non-
The spatial light field distribution standard of Chang Teshu, will more match with the luminance of outer caves, to ensure the traffic safety in tunnel.
Since any artificial light sources and sunlight has huge luminance difference, is unable to reach the matched requirement of illumination, people are not
It obtains and does not increase considerably the packing density of illuminator, the power of increase illuminator in tunnel portal section, thus in entrance
Special " reinforcing an illumination " section is formed, to alleviate the huge luminance difference inside and outside tunnel.This results in tunnel portal section to add
The construction cost of strong illumination will be doubled with operation costs, and average construction cost accounts for about entire tunnel illumination gross investment
30%, and average energy consumption more accounts for 40% or so of entire tunnel illumination total energy consumption.In addition, to make " road tunnel entrance section
Illuminating index must be with brightness matching outside Tunnel ", it is necessary to increase adaptive control system, makes it with the variation of the luminance of outer caves
And change brightness automatically, which further adds technical difficulty and construction cost that entrance reinforces illumination.Therefore tunnel enters
The reinforcement illumination of mouth section, is both current tunnel illumination energy conservation maximum energy consumption breach, even more the energy-efficient technology of tunnel illumination
Bottleneck.
Optical fiber sun light lighting is current most energy-efficient lighting engineering, it is that sunlight is introduced room using optical fiber
It is interior, to realize zero energy consumption of illumination, zero-emission.Fig. 1 show existing optical fiber sun light lighting system, it by light collection system 101,
Control system 102, Transmission system 103 and output system 104 form, and wherein light collection system 101 is collector lens, Transmission system
103 be optical fiber, and output system 104 is light lamps and lanterns, and collector lens gathers luminous energy in optical fiber, special using the low-loss of optical fiber
Property, can be by luminous energy remote transmission to optical fiber lamps and lanterns.
In view of the factor of cost, the collector lens of optical fiber sun light lighting system generally uses Fresnel Lenses, but luxuriant and rich with fragrance
The area of Nie Er lens is also impossible to the luminous flux very little that too big, single lens receive, it is therefore desirable to while using more set systems
It is likely to obtain enough luminous energy.Although cost is relatively low for Fresnel Lenses, limited by its principle, the core diameter mistake of optical fiber in addition
It is small, thus the coupling efficiency of sunlight convergence entering light fibre is lower, most luminous energy scatter and disappear all at fiber end face；Although using
Big core plastic fiber is the effective way for improving its light energy coupling efficiency, but account for about sunshine gross energy half it is ultraviolet with it is red
Outer equal black lights make the temperature of convergent point be increased to hundreds of degree suddenly after lens converge, it is sufficient to roastingization plastic optical fiber, so that
Optical fiber solar lighting system can not can only use the quartz of high cost, small core diameter using low cost, the plastic optical fiber of big core diameter
Optical fiber which increase system cost, limits its energy coupling efficiency, makes it impossible to for tunnel illumination.
In order to solve the problems, such as the energy coupling efficiency of optical fiber solar illumination, there has been proposed tunnel sunlight secondary reflections
Lighting system, as shown in Fig. 2, the system comprises the first reflecting mirror 201 and the second reflecting mirror 202, second reflecting mirror 202
It is mounted on the top of tunnel portal, first reflecting mirror 201 reflects sunlight into second reflecting mirror 202, through described
The secondary reflection of second reflecting mirror 202 injects tunnel entrance, and therefore, the system solves the coupling efficiency of lens and light
Low problem eliminates expensive transmission ray, and still, system as described in Figure 2 needs two reflecting mirrors to be used cooperatively, and increases
The difficulty of installation, and sunlight is after two secondary reflections by making the efficiency of light energy utilization too low, simultaneously as the first reflecting mirror
201 are horizontally mounted, so that the easy product such as dust, rainwater is fallen on the mirror, so that the reflectivity of reflecting mirror substantially reduces, thus
So that optical energy loss aggravates.

The sunlight of reflection injects the angle meet demand of the detector, i.e., most of light emission enters the default of the tunnel portal at this time
At position.Then at this point, executing S63.
S63: delay predetermined time；
A time interval, such as 5 minutes are set, when the absolute value of the difference is less than or equal to preset threshold, are prolonged
When 5 minutes, then execute S61.Therefore, above-mentioned tracking is executed with predetermined time interval.
For the relatively described reflecting mirror of the rotational angle of the sun, angular speed very little, if the position of reflecting mirror and the sun
It sets and meets system requirements, within the scope of certain time, even if reflecting mirror does not follow the position of the sun, the light that reflecting mirror is reflected
Convergent point and predeterminable area deviation it is very small, therefore, in order to reduce the power consumption and burden that system follows always sunlight, this
Inventive embodiments have preset a time interval, and the controller executes above-mentioned steps at predetermined intervals, will be
The duration working method of system is changed to intermittent work mode, can be effectively reduced existing tunnel portal lighting system at
