Abstract
The utility model discloses an intelligent LED lighting street lamp, comprising a photoresponse signal input circuit for collecting the external ray, wherein one end of the photoresponse signal circuit is electrically connected with a main control chip for sending different control signals based on the light signal weakness of the photoresponse signal input circuit and another end of the main control chip is electrically connected with a LED drive circuit for driving the LED weakness based on different control signals of the main control chip and the LED drive circuit is connected with the LED. The lighting state of the street lamp is automatically adjusted based on the traffic condition and the street lamp lights when the vehicle or passenger passes through the street lamp and the street lamp is at the energy saving state when no vehicle or passenger passes through the street lamp, so as to achieve the object of more energy saving and environmental protection. An AT89S51 singlechip processor outputs the PWM signal and a stable input and output loop ensures that the street lamp normally runs when the external environment is severe and the interference is too much.
Description
Technical field
The utility model relates to a kind of LED technical field, especially a kind of intelligent LED illuminating street lamp.
Background technology
Along with development of times, the urban modernization construction is constantly accelerated, and is also bigger to city illumination and city lighting engineering demand.And energy supply and demand contradiction is also more and more outstanding, and electricity saving and energy saving green illumination demand is more and more urgent, and traditional manual control, clock means of illumination can not meet the demands, and city illumination is controlled automatically and intelligent management becomes one of sign of urban modernization construction.
Yet there is diversified problem in present LED illuminating street lamp:
(1) electric power resource has been wasted in the selection of light source and lighting system; Street lamp adopts metal halide lamp more, metal halide lamp is little because of brightness height, volume, so comparative lifetime is shorter, because the restriction of material, technology, the present homemade metal halide lamp life-span still is lower than 1000 hours, and the metal halide lamp life-span of import can reach several thousand hours.Another shortcoming of metal halide lamp is to start difficulty, and is necessary with special trigger.Starting back brightness system increases gradually, if it is excessive to start energy, toggle speed is too fast, can influence bulb life, should take into full account when circuit design.Control model is single, causes the resource significant wastage.
(2) can't take into account the demand of daytime and night illumination;
(3) the not enough environmental protection of illuminating material.
The utility model content
The purpose of this utility model is to overcome prior art problems, and the intelligent LED illuminating street lamp of saving electric power resource, not influencing normal traffic circulation at night, environmental protection with a kind of is provided.
For realizing above purpose, the utility model has been taked following technical scheme: a kind of intelligent LED illuminating street lamp, include the photoinduction signal input circuit that is used to gather extraneous light, this photoinduction signal circuit one end be electrically connected be used for strong and weak and send the main control chip of different control signals according to the optical signal of the photoinduction signal input circuit that receives, be electrically connected with the led drive circuit that is used for the different control signal driving LED bright-dark degree that sends according to main control chip on the described main control chip other end, this led drive circuit is connected with LED.
Described main control chip adopts the single-chip microcomputer of AT89S51 model.The optoelectronic induction signal input circuit, realization can be regulated the street lamp state automatically according to traffic state; Design led drive circuit or adopt existing drive circuit, realize the switching of street lamp under energy-conservation and highlighted state.
The utility model compared with prior art, have following advantage: the utility model can be regulated the lighting lamp state of street lamp automatically according to traffic conditions, employing has car or pedestrian through just bright, not through then being in the novel control model of power save mode, to reach the purpose of energy-conserving and environment-protective more; Designing and producing the AT89S51 single-chip microcomputer can output pwm signal, stable input and output loop, satisfy street lamp abominable in external environment, disturb normally operation under numerous situations; Along with the maturation gradually of LED technology, impel the LED light emitting source to be widely used real-life, adopt the LED light emitting source of high brightness, low-power consumption, play energy-conservation effect more.
Description of drawings
Fig. 1 is the utility model theory diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments content of the present utility model is described in further details.
Embodiment:
As shown in Figure 1, a kind of intelligent LED illuminating street lamp includes the photoinduction signal input circuit that is used to gather extraneous light, and this photoinduction signal circuit is electrically connected with main control chip, and the main control chip other end is electrically connected with led drive circuit and LED successively.
The extraneous light that the photoinduction signal input circuit will collect converts electrical signal transfer to and gives main control chip, main control chip sends different control signals according to the signal power and gives led drive circuit, led drive circuit is according to the power of control signal, and driving LED is sent the energy-conservation light or the light of high brightness.
For guaranteeing the efficient of main control chip, the present embodiment main control chip adopts the single-chip microcomputer of AT89S51 model.
Present embodiment provides the lighting system of street lamp under vehicle after midnight, the unfrequented situation, vehicles or pedestrians is promptly arranged through near the on off state of the street lamp control automatically then, if no pedestrian or vehicle are through then being in power save mode.
Above-listed detailed description is at the specifying of the utility model possible embodiments, and this embodiment is not in order to limiting claim of the present utility model, does not allly break away from the equivalence that the utility model does and implements or change, all should be contained in the claim of this case.
Claims (2)
1. intelligent LED illuminating street lamp, it is characterized in that: include the photoinduction signal input circuit that is used to gather extraneous light, this photoinduction signal circuit one end be electrically connected be used for strong and weak and send the main control chip of different control signals according to the optical signal of the photoinduction signal input circuit that receives, be electrically connected with the led drive circuit that is used for the different control signal driving LED bright-dark degree that sends according to main control chip on the described main control chip other end, this led drive circuit is connected with LED.
