Beschreibung
Zusammenfassung:	The utility model discloses a LED street lighting comprises 4 independent LED modules, and the angle of LED module is all adjustable, and through LED drive power supply control, every LED module can independently be opened or close, can adjust the LED light source according to different lighting requirements, realizes energy -conserving purpose when guaranteeing the illumination of LED street lamp. LED drive power supply adopts constant current and constant voltage control, and for the LED module provides insulation blocking and invariable current -voltage source, response speed is fast, has overheated, excessive pressure, overcurrent protection function, guarantees the LED module and normally works. The utility model discloses an independent LED drive power supply and LED module, LED drive power supply and the heat dissipation of LED module are faster, and the reliability is higher to make the LED street lamp possess longer life, the modularized design makes LED street lighting's upgrading more simple and convenient with the maintenance, has reduced the expense and the time of maintaining the replacement.
