Description
Technical field
The present invention relates to a kind of city illumination device, be specifically related to a kind of Novel optical fiber road illumination device.
Background technology
At present roadway illumination light source mainly uses high-pressure mercury lamp, but high-pressure mercury lamp only under relatively high power competence exertion high
Light efficiency, its power is big, energy consumption is high and causes certain light pollution, more and more inadaptable modern lighting requirement.Now with energy
The day in source is becoming tight, and energy-saving and emission-reduction increasingly seem important, and such small-power ceramic gold-halogen lamp is little with its power, and light efficiency is high, color
Temperature is excellent, gradually starts to apply in engineering, but in application process, the light of low power metallic halogen lamp leads to little, it is impossible to adapt to
The street lighting requirement that major urban arterial highway is more than 12 meters, the simultaneously service life of ceramic gold-halogen lamp, the technology such as stability also need into
One step improves.The most energy-conservation roadway illumination light source should be LED illumination at present, present solar street light light source many employings LED etc.
Lower-powered light source, to reduce the configuration of system, reduces cost, but owing to major urban arterial highway is wider, road-light light-source is away from ground
Height is more than 12 meters, and the most low power LED solar street light is difficult to use at major trunk roads, and high-power LED street lamp cost is high,
And technology needs to improve, the particularly heat dissipation technology of high-powered LED lamp, if great power LED can not well be processed
The heat dissipation problem of lamp, the light decay of LED is big, the life-span is short, and the most universal LED illumination also has a segment distance.Also have one the most micro-
Ripple sulfur lamp, light efficiency is high, and the life-span is long, it also requires carry out radiating treatment, is difficult in roadway illumination application.Optical fibre illumination is as one
Plant the form of special conduction luminous energy, be widely used in recent years.It has an irreplaceable advantage of other lighting systems: as
Commercial lighting use it moment can be caused to note commodity；In museum lighting, the infrared ray in light can be exempted
With the ultraviolet damage to showpiece；It can be used in high humility, high-temperature place fool proofly, the most under water or limit, pond etc.
Be used as；In the place with fire, damp, it is also the light source of a safety, but at city illumination
Application optical fibre illumination has not yet seen relevant report.How optical fibre illumination is introduced roadway illumination；How to use efficient illumination light
Source, improve roadway illumination effect, and roadway lighting system stable, convenient for installation and maintenance, be present urban road energy-saving illumination, green
Color illumination problem demanding prompt solution.
Summary of the invention
In order to solve, China's city illumination energy consumption is high and raising energy-conserving light source is at roadway illumination effect, raising lamp system
Stability and reduce road lamp system cost.The present invention provides a kind of Novel optical fiber road illumination device.The present invention is for realizing it
The technical scheme that purpose is taked: a kind of Novel optical fiber road illumination device includes: light source, light source light splitting case, light projector filters
Sheet, convex lens, heat abstractor, optical fiber, bonder, beam splitter, luminous body, light pole, road lighting lantern.First light projector according to road
Road illumination needs to concentrate and is uniformly positioned in light source light splitting case, and light source light splitting case is provided with heat abstractor, and light source is fixed on light projector
In device, light projector is connected with optical fiber through bonder equipped with convex lens and optical filter, light projector, and optical fiber is along road pavement, at every post
Optical fiber at street lamp all has beam splitter, the luminous body that a light part for conduction in main fiber is released in road lighting lantern.
Described light source, it is characterised in that optical fiber street lamp lighting source is efficient, the approximation point source of high brightness, Ke Yiwei
High-efficiency high-power LED lamp, Efficient xenon lamp, high-efficiency ceramic Metal halogen lamp or microwave sulfur lamp.
Described light source light splitting case, it is characterised in that light source light splitting case is large-scale monolithic construction, multiple sets of light sources light projector
It is evenly distributed in light splitting case, is provided with circulation heat radiator in light source light splitting case, uses air-cooled or water-cooling, it is ensured that system
Work in normal circumstances.
Described light projector, it is characterised in that be provided with collecting lens in light projector, the light that light source is sent is by focusing on
After, filtered filtering ultraviolet line, project on fiber coupler, transmission is to optical fiber.
Described beam splitter, it is characterised in that below light pole foundation ground, all has beam splitter, beam splitter at main fiber
Couple with main fiber, the luminous body that the fiber section of transmission in main fiber is released in road lighting lantern.
Beneficial effects of the present invention
1, owing to have employed fiber optic conduction light, substantially increase the service efficiency of light source, deduct electric energy at circuit simultaneously
In loss, saved the energy and safe and reliable.
2, owing to have employed light source centralized arrangement, use radiating treatment simultaneously, enhance the service life of light source, improve
The luminous efficiency of light source.
3, original Split type street lamp is changed into centralized Control, the light source of original on a high pole is changed into ground control, former
Carry out single source to be difficult to carry out radiating treatment and change centralized cycle radiating treatment into, solve the heat dissipation problem of high efficiency light source, so
Just enhance the stability of system, facilitate installation and the maintenance of street lamp, reduce operating cost, beneficially energy-saving and emission-reduction.
Owing to have employed technique scheme, so that the present invention solves the system that energy-efficient light source is applied at major trunk roads in fact
About condition, energy-efficient light source and optical fiber organically combine, it is achieved that roadway lighting system energy-efficient, system reliable and stable and
The realization of low cost feature, beneficially target for energy-saving and emission-reduction.
