Description
Technical field
The utility model relates to a kind of solar LED illumination device, a kind of energy-conservation solar LED illumination device of saying so more specifically.
Background technology
LED is the cold light source of new generation that grows up; have the conventional light source incomparable advantage: energy savings, protection environment, life-span be long, reduce maintenance cost, better light quality is provided, improve light visual effect and fail safe, and these advantages make the LED technology more and more be used in numerous infrastructure constructions.Led light source be called as after incandescent lamp, fluorescent lamp and high strength Gas lamp the 4th generation light source.Solar LED illuminating system is owing to lacked inverter circuit, and the middle loss of energy will be much smaller than the AC energy saving lamp illuminating system.LED lamp life-span difference reaches 100,000 hours, and common energy-saving lamp is also just in 10,000 hours, so the LED lamp has its advantage in the maintenance of light fixture.The optical efficiency height of LED lamp, under same light was shone, LED lamp power consumption will be lower than electricity-saving lamp.LED lamp adverse environment resistant ability is higher, especially to big meaning is arranged in outdoor illumination.Though general solar LED street lamp can satisfy basic illumination needs at present, but do not waste in vain owing to consider the energy that effective utilization of the energy causes store many daytimes, for example the brightness of street lamp remains unchanged always, power loss can not be according to the variation of surrounding environment and timely adjustment, and therefore designing a kind of energy-saving solar LED road lamp system becomes instant requirement.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of low cost of manufacture, long service life, can control automatically and the solar LED illumination device of energy savings.
The technical scheme that the utility model solves above-mentioned technical problem is: comprise optical detection device, signal comparator, controller, LED lamp drive circuit, LED lamp and solar battery group, the signal output part of described optical detection device is connected with the input of signal comparator, the output of signal comparator is connected with the input of controller, the output of controller is connected with led drive circuit, led drive circuit is connected with the LED lamp, and solar battery group is connected with led drive circuit.
Further, described controller is the STC89C52 single-chip microcomputer.
Because adopt technique scheme, the beneficial effects of the utility model are: owing to adopted the control of single-chip microcomputer, can adjust the brightness of LED lamp, play the effect of energy savings according to different ambient conditions to the LED lamp drive circuit.
Description of drawings

Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
A kind of as shown in Figure 1 solar LED illumination device, comprise optical detection device 1, signal comparator 2, controller 3, LED lamp drive circuit 4, LED lamp 5 and solar battery group 6, the signal output part of described optical detection device 1 is connected with the input of signal comparator 2, the output of signal comparator 2 is connected with the input of controller 3, the output of controller 3 is connected with led drive circuit 4, led drive circuit 4 is connected with LED lamp 5, and solar battery group 6 is connected with led drive circuit 4.Controller 3 is the STC89C52 single-chip microcomputer.
As shown in Figure 2, operation principle of the present utility model is: during work, optical detection device detects outside voltage signal of light intensity generation and the set voltage of signal comparator and compares, if be lower than the signal value of signal comparator then provide a signal to single-chip microcomputer STC89C52, how single-chip microcomputer STC89C52 determines the driving LED drive circuit by the signal value that receives.Owing to directly be difficult to drive the LED street lamp of high briliancy, therefore adopt drive circuit driving LED lamp as shown in Figure 3 from the level of single-chip microcomputer STC89C52 pin output.Drive circuit is the constant-current LED drive circuit by the solar battery group power supply.Signal comparator is connected with single-chip microcomputer.D1 is a Zener diode, is added in as constant pressure source on the base stage of Q1, because base bias is stable, collector current Ic can not change even voltage source changes collector current Ic along with stable yet yet, can guarantee electric current and brightness stability.After the single-chip microcomputer power supply, can control the environment of different periods by single-chip microcomputer STC89C52, reach the purpose of energy savings.
