Description
Technical field
The utility model relates to a kind of LED illuminator, especially a kind of solar powered LED illuminator of using to outdoor billboard.
Background technology
The high speed billboard set up two effects: (1) is to show a local window.Most of billboard concentrates on the high speed gateway or from closer place, city, generally is the advertisement of local surging enterprise and distinguishing products.Especially the national trunk highway vehicle is from various parts of the country for highway, so near the advertisement the gateway, city has become local city business card.(2) some colors have been increased for uniform highway.At running on expressway, identical on the way landscape lets driver and passenger feel dull easily, and the billboard that occurs frequently provides some enjoyment for driver and passenger.
At present, the general shot-light (projection floodlight) that adopts of the evening of outdoor billboard illumination, wherein using more is high-pressure mercury lamp shot-light or Metal halogen lamp, also has part to begin to adopt the LED shot-light.Whether need adopt night illumination (playing lamp) to the high speed billboard, the price of billboard also can be different, and the price that generally will adopt night illumination is about 20,000.When adopting high-pressure mercury lamp as main light source; There are many problems such as the big operating cost of power consumption is high, short fault rate of life-span is high, cable construction is complicated, safety coefficient is low, the maintenance management cost high, light pollution is serious; If combine with solar energy, too high power has increased the cost of solar panel and the cost of system converter.
The utility model content
The utility model provides a kind of solar powered LED illuminator of using to outdoor billboard to the defective of above-mentioned existence, can effectively reduce operation and maintenance cost, long service life.
A kind of solar powered intellectualized LED illuminator is characterized in that comprising power circuit and control circuit, and described power circuit comprises solar panel, charge controller, batteries and the LED light fixture module that connects successively; Described control circuit comprises the accumulator voltage detecting circuit that joins with batteries; Be used to control LED light fixture module luminous Control System of Microcomputer and photosensitive detector, described photosensitive detector and accumulator voltage detecting circuit all insert Control System of Microcomputer.Solar panel receives solar energy, output current and voltage variable signal daytime.Charge controller accumulators group on the one hand charges, and realizes the maximal power tracing (MPPT) to solar panel on the other hand, and unnecessary solar panel energy is offered LED light fixture module.Batteries is charged with makeup energy by solar energy daytime, and evening or rainy weather are given the power supply of LED light fixture module.Accumulator voltage detecting circuit detects battery tension, and the output signal is sent to Control System of Microcomputer.Control System of Microcomputer is according to the mode of operation of detected battery tension adjustment LED light fixture, prevents on the other hand that batteries from crossing to put.Photosensitive detector detects outside light intensity, and the output signal is sent to Control System of Microcomputer.Control System of Microcomputer determines the unlatching work and the turn-off time of LED light fixture according to detected outside light intensity.
Described LED light fixture module comprises LED light fixture and the led drive circuit with PWM dimming function.
Utilize above-mentioned intellectualized LED illuminator, every separated fixedly period of described Control System of Microcomputer regularly produces the adjustable pulse signal of pulsewidth the LED light fixture is carried out light modulation to reduce the power of LED.
After photosensitive detector detects darkness; Open full power output in back 4 hours by Control System of Microcomputer control LED light fixture, 4 as a child back LED light fixture power outputs reduce by half, and LED light fixture power output reduces by half again after 4 hours again; After photosensitive detector detects daybreak; The LED light fixture is closed, photosensitive detector detect after the darkness LED light fixture again full power open so circulation.Belonged to the wagon flow peak period in 4 hours after lamp is opened, the output of LED light fixture full power along with vehicle flowrate descends, progressively reduces lighting power afterwards in this cycle.The minimizing of adopting above-mentioned control strategy can realize with the sky to be the total energy of unit LED light fixture is about half, and promptly solar panel and batteries capacity reduce about half, thereby have reduced total initial cost and the follow-up maintenance cost of system.Above-mentioned control strategy can change according to the actual requirements and further optimize.
The utility model beneficial effect is:
1. system can be installed in the billboard location that common civil power can't be sent to easily; Be particularly useful for the place that highway, national highway, provincial highway both sides and city suburbs, rural area etc. are not easy to carry distribution, greatly help the market development and the additional income of advertisement operators.
2. a large amount of initial hardware input and construction cost have been practiced thrift; Operation costs of use such as a large amount of electricity charge have been practiced thrift.
3. the system maintenance cost is low, long service life; Security of system, environmental protection, no potential safety hazard; Construction can no longer need to carry out numerous and diverse examination and approval procedures between the government departments such as advertisement operators and municipal electric power.
Description of drawings:
Fig. 1 is the Circuits System block diagram of the utility model;
Fig. 2 is the control flow chart of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model content is described further.
As shown in Figure 1, the LED illuminator of solar powered outdoor billboard comprises power circuit and control circuit two parts.Power circuit comprises solar panel 101, charge controller 102, batteries 103 and the LED light fixture module 104 that connects successively.LED light fixture module 104 comprises LED light fixture and the led drive circuit with PWM dimming function.Control circuit comprises the accumulator voltage detecting circuit 201 that joins with batteries 103; Be used to control LED light fixture module 104 luminous Control System of Microcomputer 202 and photosensitive detector 203, photosensitive detector 203 all inserts Control System of Microcomputer with accumulator voltage detecting circuit 201.
