Technical field
The present invention is about a kind of Intelligent road lighting system, the Intelligent road lighting system of a kind of distributing Self Adaptive Control.
Background technology
Along with the continuous quickening of Urbanization in China, the scope in city is expanding, and the demand of urban transportation illumination grows with each passing day.
City is bright, and while figure beauty, the expense that street lighting produces too increases.
Traditional street lighting uses monoblock type to control, and the most sheet of street lamp is controlled by a main switch, the only operation of on and off.
, there is a warm in the gas-discharge lamps such as traditional street lighting many employings high-pressure mercury lamp, had not only wasted resource but also not on startup
It is beneficial to intelligentized control method.Traditional road-light light-source is all that the mechanism using mercury vapour is come luminous, and the process of its waste and old light source also becomes
The problem that solution is needed in the whole world badly.Traditional road-light light-source is that omnidirectional is luminous, and reflector need to be coordinated to use, and light losing is relatively big, profit
Relatively low by rate.
Existing street lamp is by judging that Natural light intensity opens illumination less than certain value, and has one to delay when traditional street lamp is opened
Slow warm.Under conventional road lamp system, street lamp controlled state in the on state is constant.Morning and at dusk time-division,
Human eye can substantially identification object, only need street lamp provide the low light level normally walk driving when, roadway lighting system is
Full-load operation, this phenomenon is the waste to electric power resource.Vehicle flowrate is the least at dead of night, the small city of especially 45 lines
The fact that vehicle flowrate is substantially zeroed after midnight in city under premise, the normally opened of street lamp is the significant wastage to electric power resource.
Society now, people increasingly focus on energy-saving and emission-reduction, and the idea of sustainable development has been rooted in the hearts of the people.In recent years, state
Family makes great efforts to promote the development of semiconductor lighting industry, puts into effect behaves such as such as " ten ten thousand, cities " and promotes the development of semiconductor lighting.
Increasing city illumination begins with LED light source, and the saving meanwhile bringing the energy utilizes.
The present invention, based on LED light source as lighting control objects, uses decentralised control, it is achieved that the self adaptation of roadway illumination is adjusted
Joint, realizes the most intelligent control on the basis of original LED energy-saving effect, optimized algorithm structure in Single-chip Controlling, more greatly
Degree achieve resources conservation.
