Detailed description of the invention

The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.

With reference to Fig. 1, photovoltaic commercial power complementation LED highway tunnel illumination system, comprising: photovoltaic plant, mains supply system, long distance control system, LED tunnel lamp.

Described mains supply system and photovoltaic plant are connected with DC voltage by change-over switch and shield, and DC voltage is delivered in LED tunnel lamp by described DC voltage screen.

On sunlight sufficient daytime, the DC voltage that photovoltaic plant exports, delivers in LED tunnel lamp by DC voltage screen, and input voltage is converted to constant current supply LED tunnel lamp by the constant-current controller in LED tunnel lamp.

After The night screen has hung down, sunlight gradually dimmed or cloudy weather for several days running sky time, photovoltaic plant exports the requirement that dc power can not meet LED tunnel lamp, in order to continuous illumination, pass through change-over switch, electrical network output AC voltage, is converted to DC voltage by switching rectifier, powers shielding through DC voltage to LED tunnel lamp.

Remote monitoring center manipulates Centralized Controller by network remote.Centralized Controller implements management and control by the single-lamp controller be arranged in LED Tunnel Lamp to Tunnel Lamp.

Self adaptation light adjusting system is made up of optical sensor and the constant-current controller being arranged on LED tunnel lamp.Optical sensor mainly detects the light intensity outside tunnel, and the effect of constant-current controller changes lamplight brightness, and the general power of LED tunnel lamp should adapt with the general power of photovoltaic plant.After sunrise, outside tunnel, light intensity increases gradually, and photovoltaic plant power output also increases gradually, and the brightness of Tunnel Lamp also increases gradually.Noon, the reduction all corresponding to Tunnel Lamp power demand of photovoltaic plant power output.The power output of photovoltaic plant fortunately meets this feature.Dimmed outside night tunnel, long distance control system can realize LED half-power and power.

Self adaptation light adjusting system detects the power of sunlight by light-sensitive device, and by the constant-current controller in LED tunnel lamp, the brightness of adjustment light, had both met tunnel illumination requirement, did not occur again the light pollution wasting electric energy.

Photovoltaic plant mainly comprises photovoltaic cell component, photovoltaic cell support, controller, solar energy is the most general on the earth, also be the most clean energy, can be described as inexhaustible regenerative resource, when daylight is stronger, photovoltaic cell component accepts solar radiation energy and is converted to that electric energy exports, this electric energy directly can supply LED tunnel lamp, also can be stored in battery.What current photovoltaic plant was conventional has monocrystalline silicon, polysilicon and amorphous silicon photovoltaic assembly.This assembly adopts the safety glass encapsulation of high transmission rate, and there is the backboard of aging-resistant glued membrane and high strength on surface, has that efficiency is high, the life-span is long and safeguards the advantages such as anti-ice hail intensity is large.

The Main Function of photovoltaic cell support is fixed light photovoltaic cell components, in order to ensure that photovoltaic cell component accepted solar radiant energy as much as possible in 1 year, photovoltaic cell component should have certain inclination angle, and optimum angle of incidence is not identical yet from different places, and optimum inclination angle is 90 degree.Therefore photovoltaic cell support is in the photovoltaic power supply system of different regions, and in structure, very important problem is exactly wind force proofing design, and therefore, the support of photovoltaic module must have very high mechanical strength, meets wind resistance requirement.

Controller in photovoltaic system mainly completes light-operated, space-time and the function such as anti-reverse, if configuration battery energy storage device, also should have light and put point control and defencive function.

With reference to Fig. 2, mains-supplied system comprises switching rectifier, switching rectifier mainly comprises input rectifying filter circuit, circuit of power factor correction, PWM frequency conversion inverter circuit, exports rectification and filter circuit, as shown in Figure 2, in order to ensure switching rectifier reliable power supply, usually all adopt the redundant system that N+1 wired in parallel is powered.A module breaks down, and other modules still can ensure enough power outputs, guarantees that tunnel illumination is uninterrupted.

With reference to Fig. 3, long distance control system is primarily of part compositions such as Surveillance center, Centralized Controller and single-lamp controllers.

Surveillance center is positioned at the Administrative Area of tunnel illumination administrative staff,

The Centralized Controller be arranged in DC voltage screen accepts Surveillance center's order by wireless GPRS, implements Tunnel Lamp management and controls, and utilizes PLC technology to send single lamp terminal and orders and complete information feed back.

Be installed on the single-lamp controller in LED tunnel lamp, adopt PLC technology, accepted the instruction of Surveillance center by Centralized Controller, realize the switch control rule of LED tunnel lamp, fault information reporting, single lamp data acquisition, the kinetic energy such as single lamp electric energy metrical.

LED tunnel lamp: photovoltaic power supply system exports DC voltage, so do not need in LED tunnel lamp to install frequency conversion Switching Power Supply, during network supply, at switchboard built with friendship Switching Power Supply frequently, so, only need in LED tunnel lamp to install simple constant-current supply additional, so not only LED tunnel lamp cost significantly reduces, and reliability significantly improves.

In order to realize remote monitoring, single lamp control terminal being also housed in LED tunnel lamp, various monitoring and controlling function can be realized.
