Abstract
The utility model relates to an intelligent induction energy-saving street lamp, which is provided with a human body induction sensor, wherein the human body induction sensor is connected with the street lamp, is a passive infrared human body induction sensor and is arranged on a lamp pole of the street lamp. The intelligent induction energy-saving street lamp is characterized in that whether people pass through the pavement is induced through the human body induction sensor additionally arranged in a proper height position of an upright post of the street lamp, the brightness of the street lamp is controlled, the device has a simple structure, required additional devices are few, energy sources are saved, and the service life of the street lamp is prolonged.
Description
Technical field
The utility model relates to the road lighting field, relates in particular to a kind of street lamp.
Background technology
The electric energy that China's illumination at present consumes accounts for 10%～20% of electrical production total amount, and the city public illumination then accounts for 30% ratio in the illumination power consumption.The international lighting field has proposed the illumination new ideas of TPO (Time/Place/Occasion) in recent years, i.e. " power supply as required, economize on electricity displays a light under the situation that guarantees illuminating effect ".In China, the design of the street lamp of most residential quarters is fairly simple, only goes to consider that the brightness that has is too strong, not only causes energy waste, and causes light pollution easily from the angle of illumination basically; What have considers energy-conservation aspect, and the economical method that has adopted street lamp to turn off the light every small cup makes the sub-district street lamp form zebra stripes, and the result has caused the road illumination skewness, has buried hidden danger to public security and traffic safety.
It is reported, what the above street lamp of China used all is high-pressure mercury lamp, the design service life of sodium vapor lamp is 24000 hours, but because voltage pulsation substantially exceeds about 15% of rated voltage, particularly after midnight, power load reduces makes electrical network sometimes near 245V, and lose surprising on average less than 1 year the actual life that causes bulb.Most streets and dwelling house street lamp can not be avoided after midnight because of the rising of the line voltage impairment to the street lamp life-span.Thereby it is illusory that the part street lamp is formed, and causes covert waste, makes troubles for resident's life.
The utility model content
In order to solve problems such as energy waste, street lamp weak point in service life, the utility model provides a kind of intelligent-induction energy-conserving road lamp.
The technical scheme that the utility model is adopted for achieving the above object is: a kind of intelligent-induction energy-conserving road lamp is characterized in that: human body sensor is installed, and human body sensor is connected with street lamp.
Described human body sensor is the passive infrared human body sensor.
Described human body sensor is installed on the lamp stand of street lamp.
Intelligent-induction energy-conserving road lamp of the present utility model, by on the suitable height and position of the column of street lamp, set up human body sensor respond to the road surface whether the someone pass through and control street lamp brightness, apparatus structure is simple, required attachment device is less, energy savings prolongs the street lamp life-span.
Description of drawings
Fig. 1 is the utility model human body sensing device circuit theory diagrams;
Fig. 2 is the utility model voltage-regulation principle schematic diagram;
The specific embodiment
Intelligent-induction energy-conserving road lamp of the present utility model, detect people from road surface whether arranged by on the suitable height and position of street lamp post, setting up human body sensor, human body sensor is the passive infrared human body sensor, be connected by circuit with street lamp, control the brightness of street lamp by the output signal of human body sensor.Make street lamp be operated in specified when there is the people on the road surface or near rated condition, this moment, the lighting tube brightness value was higher, made things convenient for the pedestrian; Nobody the time, when particularly the road surface was basic unmanned movable in the second half of the night, end user's body induction sensor came the perception surrounding environment, reduced the voltage of road lamp tube by the output signal of human body sensor, and its luminous intensity values is reduced.
Fig. 1 is the circuit diagram of human body sensor, used the passive infrared human body sensor in the circuit, model is KDS9, C1 is a filter resistance, Q1 is a triode 9014, amplifier chip NE5532, and a unit amplifies as signal, the another one unit is used for comparison output logic level, and Rp is for regulating the comparison threshold voltage resistance.
When probe receives after heat that human body discharges releases infrared signal, become a faint low frequency signal of the about 0.3Hz～3Hz of frequency by a control internal conversion, input voltage comparator U1A after Q1, U1B dual-stage amplifier amplify, wherein RP is the reference voltage regulator potentiometer, be used for regulating circuit sensitivity, just investigative range.
During the unmanned state, reference voltage (U1A homophase pin voltage) is higher than the output voltage (the reverse pin voltage of U1A) of U1B, and U1A exports high level.When the people entered investigative range, probe output detecting voltage made signal output voltage be higher than reference voltage after Q1 and U1B amplification, at this moment the output pin output low level of U1A.This high-low level signal is controlled follow-up regulating circuit as the signal of control circuit.
Regulating circuit adopts controllable silicon chopper-type lighting device, and as shown in Figure 2, by the angle of flow of control IGCT (controllable silicon), the sine voltage that electrical network is imported cuts away a part, makes voltage reduce by 20% with interior operation.
