Abstract
The utility model discloses a LED lamps and lanterns of automatic adaptation of high -low pressure, inside voltage testing, three drive circuit and the drive output of being equipped with of lamp housing, three drive circuit's input is connected respectively to voltage testing input connection external power source, output, and drive output input is all connected to three drive circuit output, and the output of drive output concatenates the light source of LED lamps and lanterns, and three drive circuit's operating voltage scope scales up in proper order, after inserting the power, can carry out detection and analysis to the operating voltage who inserts the power, select to drive lamps and lanterns work with inserting the drive circuit that the source phase matees, enable lamps and lanterns and avoid the damage that brings because of the voltage unstability.
Description
Technical field
The utility model relates to a kind of LED street lamp light fixture, to road, bridge, park and other places in night illumination.
Background technology
At present, road lighting brings into use LED street lamp to replace traditional high-pressure mercury lamp substantially, in order to improve the service life of LED street lamp, requires that LED street lamp preferably works when stable operating voltage.But in less developed country and area, because the reason of circuit makes spread of voltage, cause light fixture to occur a large amount of faults and damage.
Summary of the invention
The purpose of this utility model is to overcome the problems referred to above that existing LED lamp occurs in use, provides a kind of high-low pressure self-reacting LED lamp, can in high-low pressure situation steady operation, improve service life.
The technical scheme that the utility model is adopted for achieving the above object is: the utility model outside is lamp casing, lamp casing inside is provided with voltage detection module, first LED drive circuit, second LED drive circuit, 3rd LED drive circuit and drive output, voltage detection module input connects external power source, output connects the first LED drive circuit respectively, the input of the second LED drive circuit and the 3rd these three drive circuits of LED drive circuit, three drive circuit outputs all connect drive output input, the light source of the output serial connection LED lamp of drive output.
The operating voltage range of described three drive circuits increases progressively successively, the operating voltage range of the first LED drive circuit is ADC12-100V, the operating voltage range of the second LED drive circuit is ADC100-240V, and the operating voltage range of the 3rd LED drive circuit is ADC240-380V.
The advantage that the utility model has after adopting technique scheme is: the utility model is after access power supply, determination and analysis can be carried out to the operating voltage of access power supply, to select with the drive circuit that matches of access power supply to drive light fixture work, the damage that light fixture is avoided because spread of voltage brings can be made.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1. voltage detection module; 2. the first LED drive circuit; 3. the second LED drive circuit; 4. the 3rd LED drive circuit; 5. drive output; 6. lamp casing.
Detailed description of the invention
See Fig. 1, LED lamp outside is lamp casing 6, and lamp casing 6 material is die casting aluminium.Voltage detection module 1, first LED drive circuit 2, second LED drive circuit 3, the 3rd LED drive circuit 4 and drive output 5 is provided with in lamp casing 6 inside.The input of voltage detection module 1 connects external power source, and external power source provides power supply for whole LED lamp.Voltage detection module 1 has the voltage detecting analytic function to input, is commercial module.
The output of voltage detection module 1 connects the input of the first LED drive circuit 2, second LED drive circuit 3 and the 3rd LED drive circuit 4 respectively.First LED drive circuit 2, second LED drive circuit 3 and the output of the 3rd LED drive circuit 4 are all connected the input of drive output 5, the light source of the output serial connection LED lamp of drive output 5.
First LED drive circuit 2, second LED drive circuit 3 is different with the operating voltage range of the 3rd these three drive circuits of LED drive circuit 4, increases progressively successively.The operating voltage range of the first LED drive circuit 2 is ADC12-100V, and the operating voltage range of the second LED drive circuit 3 is ADC100-240V, and the operating voltage range of the 3rd LED drive circuit 4 is ADC240-380V.
During utility model works, access external power source, first voltage detection module 1 carries out determination and analysis to the operating voltage of input, the operating voltage of analysis result and three drive circuits is compared, connect the drive circuit mated most with input voltage, export to LED light source finally by drive output 5, make LED light source automatically adapt to the high-low voltage inputted, increase the service life.
The foregoing is only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and inventive concept thereof and replace or change, all should be encompassed within protection domain of the present utility model.
