Abstract
The utility model discloses an intelligent electricity-saving LED street lamp, which comprises an LED street lamp and a power supply module for supply power for the LED street lamp. The intelligent electricity-saving LED street lamp further comprises: firstly, an LED current control module electrically connected between the power supply module and the LED street lamp and used for controlling current input into the LED street lamp, secondly, a moving object detector used for sensing whether or not moving objects exist within set range, and thirdly, a signal processing and controlling module electrically connected between the LED current control module and the moving object detector and used for judging sensing signals returned from the moving object detector and outputting control signals to the LED current control module. The intelligent electricity-saving LED street lamp can lower the LED street lamp brightness when no one passes near the street lamp and the lamp is in idle, thereby improving utilization efficiency of electricity, and saving energy sources.
Description
Technical field
The utility model relates to a kind of intelligent energy-saving LED street lamp.
Background technology
LED (light emitting diode) has that energy consumption is low, caloric value is lower and the advantage of long service life, and in today of global energy shortage, LED has wide application space.With regard to the LED street lamp, use location and usage time interval at some, might be for a long time no one's processes all, this moment street lamp with have that man-hour brightness is the same will to cause bigger waste, answer the trend of world's carbon reduction, the design of new LED street lamp also should consider how to improve effective rate of utilization to reduce vacant waste when practical application except the characteristics of the high light efficiency of power saving that utilizes new LED.
LED flows through LED in its current limitation parameter area electric current is big more, and its luminosity is just high more, i.e. the brightness of LED is directly proportional with electric current by LED.A kind of PWM (pulsewidth modulation) dimming mode that is is arranged in the regulative mode to LED brightness, pwm signal can be produced by cpu controller, also can produce by other pulse signal, the electric current that pwm signal can be controlled by the LED lamp changes to the normal current state from 0, can make the LED lamp from secretly becoming normal brightness, dutycycle big more (high level time is long), the LED brighter display.
Summary of the invention
The utility model purpose provides a kind of intelligent energy-saving LED street lamp, around the street lamp nobody through and when idle, the street lamp brightness of LED is lower, has improved the utilization ratio of electric energy, has saved the energy.
The technical solution of the utility model is: a kind of intelligent energy-saving LED street lamp, comprise LED street lamp and the power module that the LED street lamp is powered, and described intelligent energy-saving LED street lamp also comprises:
---the LED current control module, be electrically connected between described power module and the LED street lamp, be used for the electric current of input LED street lamp is controlled;
---the detecting moving object device is used to respond to whether mobile object is arranged in the setting range;
---signal is handled and control module, is electrically connected between described LED current control module and the detecting moving object device, is used for the induced signal that the detecting moving object device returns is judged and output a control signal to the LED current control module.
Further, in above-mentioned intelligent energy-saving LED street lamp, described LED current control module is the PWM controller.The duty that utilizes the control of PWM controller to import the power supply of LED street lamp is recently controlled the brightness of LED, and is very easy to use and flexible.
Further, in above-mentioned intelligent energy-saving LED street lamp, described power module is for to be converted to galvanic AC/DC converter with electric main.
During use, the detecting moving object device carries out detecting real-time to having or not mobile object in the desired location scope, and real-time a signal that receives is transferred to that signal is handled and control module in, signal is handled and control module compares differentiation to the received signal.If think the having or not when identical before of mobile object in the desired location scope after differentiating---do not have mobile object before, do not have mobile object now yet; Mobile object is arranged before perhaps, have also now that mobile object---the LED current control module is kept former output current.If think the having or not when changing before of mobile object in the desired location scope after differentiating, then signal is handled and control module is sent control signal and made its change electric current output state to the LED current control module.As there not being mobile object before, LED current control module control electric current is with lower dutycycle power supply, and the LED street lamp sends darker light; Mobile object appears in the desired location scope and differentiate the back judgement, then signal is handled and control module is sent control signal and allowed LED current control module control power supply with higher dutycycle power supply, make the LED street lamp send higher light, illuminate road for the people in the desired location scope.
The utility model advantage is:
Export brighter and darker two kinds of brightness when 1, the utility model has people's process and no one near the LED street lamp respectively, the utilization rate of the power supply of feasible input LED street lamp improves, and has saved electric energy.
2, the utility model can judge automatically whether the someone passes through on the road surface, and regulates the output brightness of LED street lamp automatically, and is easy to use.
Description of drawings
Fig. 1 is the utility model specific embodiment structure principle chart.
Wherein: the 1LED street lamp; 2 power modules; The 3LED current control module; 4 detecting moving object devices; 5 signals are handled and control module; 6 civil powers.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: as shown in Figure 1, a kind of intelligent energy-saving LED street lamp comprises LED street lamp 1 and the power module 2 that LED street lamp 1 is powered, and described intelligent energy-saving LED street lamp also comprises:
---LED current control module 3, be electrically connected between described power module 2 and the LED street lamp 1, be used for the electric current of input LED street lamp 1 is controlled;
---detecting moving object device 4 is used to respond to whether mobile object is arranged in the desired location scope;
---signal is handled and control module 5, is electrically connected between described LED current control module 3 and the detecting moving object device 4, is used for the induced signal that detecting moving object device 4 returns is judged and output a control signal to LED current control module 3.
Described LED current control module 3 is the PWM controller.
Described power module 2 is for to be converted to galvanic AC/DC converter with electric main 6.
The desired location scope is 200 meters scopes of circumference in the present embodiment.During work, detecting moving object device 4 detects and have or not mobile object in 200 meters scope, outputs a control signal to the power supply that LED current control module 3 is controlled the LED street lamp after being judged by signal processing and control module 5.
When detecting no mobile object, the control of PWM controller is with the power supply of 50/50 dutycycle, and the brightness of LED lamp is half of operate as normal brightness;
In the time of in mobile objects such as detecting traffic enters 200 meters scopes, signal is handled and control module 5 output signals make it to supply power to total power to the PWM controller.
The utility model around the street lamp nobody through and when idle, the street lamp brightness of LED reduces, and has improved the utilization ratio of electric energy, has saved the energy.
