| titleOfInvention | A kind of LED lamp, LED lamp tube and its constant-current drive circuit |
| abstract | The present invention provides a kind of LED lamp, LED lamp tube and its constant-current drive circuits, are suitable for electronic technology field.Wherein, the constant-current drive circuit of LED lamp tube, comprising: pipeline start up by preheating module, constant-current control module and output module；When LED lamp tube connects alternating current by ballast, voltage matches exchange according to first that ballast exports with rectification module and are electrically generated the first direct current, and the first direct current electricity output is preheated to pipeline start up by preheating module, when pipeline start up by preheating module is completed to preheat according to the first direct current, the circuit that pipeline start up by preheating module, output module and LED are formed is switched on, and pipeline start up by preheating module is to constant-current control module output services electricity consumption；Electric signal on constant-current control module acquisition circuit, and judge whether to shunt circuit according to electric signal, the specification of the work electricity consumption when alternating current by ballast output is avoided with LED lamp tube when not being consistent with electrical specification, the phenomenon that causing LED lamp tube that can not work or burn, increases the scope of application of LED lamp tube. |
