Description

A kind of intelligent LED street lamp

Technical field

The utility model relates to a kind of LED street lamp, especially a kind of intelligent LED street lamp of opening as required or closing.

Background technology

In the modern society that advocates low-carbon environment-friendly, need exploitation energetically to possess the equipment of power saving function, street lamp is means of transportation commonly used, be to illuminate the requisite facility of road night, guarantee the safe passing of vehicle, but in a wagon flow less area, light yellow all night during street lamp during night, the not enough energy savings of such street lamp is wasted electric energy greatly.

The utility model content

The technical problems to be solved in the utility model be realize a kind of can be according to the LED street lamp that whether has the pedestrian to open or close on the road.

To achieve these goals, the technical solution adopted in the utility model is: a kind of intelligent LED street lamp is provided with radar inductor and far infrared human body detector, the input of controller and radar inductor and far infrared human body detector are connected and handle the detectable signal of its reception, described controller output end is connected with the driver element input, and described driver element output is connected with the LED lamp.

The LED street lamp also is provided with solar panels and the solar cell into the power supply of LED lamp.

Described solar panels and solar cell are the power supply of LED lamp by wireless charging system, and described wireless charging system comprises rectification filtering unit, the full-bridge LLC controlled resonant converter of the back signal that is used to accept filter, the weak coupling transformer that obtains signal after the conversion and the charge mode controller of control weak coupling transformer secondary voltage output.

Described controller comprises establishes clock control cell that is used for default lighting time and the pulse bandwidth control module that is used to control street lamp brightness.

Advantage of the present utility model drives the LED street lamp through driver element by clock control after being by radio unit and sensing cell the pedestrian that walks on the time channel midnight and driving vehicle to be detected accurately again, makes its work; This LED lamp post structure and principle are simple, with low cost, also by to LED street lamp time-delay control, have realized purpose of energy saving.

For reasonable energy utilization, the power supply of LED street lamp adopts solar cell to power, and passes through the battery of setting again, thereby makes the LED street lamp not influence its operate as normal by storage battery power supply when rainy day or cloudy day.

Controller, clock control cell, LED lamp driver element, infrared human body detector, radar inductor are contained in proper order on the street lamp and can bring into play the Energy Saving Control effect; Can be applied to energy-conserving road lamp system of community, rural area energy-conserving road lamp system, and the energy-conserving road lamp system of non-main roads.

The specific embodiment

Referring to Fig. 1 as can be known, intelligent LED street lamp of the present utility model is to add induction installation and control device on the basis of existing LED street lamp, induction installation is radar inductor 2 and far infrared human body detector 1, radar inductor 2 is used for the sensing mobile object, and far infrared human body detector 1 is used for the sensing pedestrian; Control device is a controller 3, its input is connected with the output of radar inductor 2 with far infrared human body detector 1, receive, handle the output signal of induction installation, its output is connected with driver element 4 inputs, the output of driver element 4 is connected with LED lamp 5, controller 3 is thought when needing to open LED lamp 5 after through judgement, then outputs control signals to driver element 4, is driven by driver element 4 and opens LED lamp 5.The controller 3 of this intelligent LED street lamp mainly by the clock control cell 301 that is used for default lighting time and the pulse bandwidth control module 302 that is used to control street lamp brightness form, wherein, when clock control cell 301 arrives at default lighting time, 3 of controllers allow LED street lamp driver element 4 driving LED lamps 5 in 1/2 (or 1/3) brightness, close as the pedestrian, when allowing far infrared human body detector 1 sense, immediately LED street lamp 5 is adjusted to bright entirely, and notify the street lamp of front/rear bar with radio unit, reaching the highway section of having only pedestrian or driving just has the street lamp of lighting; The time ratio that the LED lamp is lighted can be adjusted according to the peak pulse duration of the control signal of accepting in the PWM input port that the constant current source LED lamp drives, and output interface is supplied with the LED lamp current.In 301 its times of clock control cell of establishing can set by the Add-In programmable device and start, close the street lamp time point, complete bright time segment length, and the brightness of general period.

The power supply of the LED lamp 5 of the utility model intelligent LED street lamp can adopt wired mode to its direct power supply by solar panels and solar cell 7, perhaps referring to the embodiment of Fig. 2, the electric energy that solar panels and solar cell 7 receive is by 5 power supplies of 6 pairs of LED lamps of wireless charging system, referring to Fig. 3 as can be known, wireless charging system 6 comprises rectification filtering unit 601, the full-bridge LLC controlled resonant converter 602 of signal after being used to accept filter, obtain the weak coupling transformer 603 of signal after the conversion and the charge mode controller 604 of control weak coupling transformer 603 secondary voltages output.
