Abstract

The invention is suitable for the LED lamp field and provides a LED street lamp and a driving power supply circuit thereof. In an embodiment of the invention, the driving power supply circuit of the LED lamp comprises: an AC / DC constant voltage driving unit and more than one DC / DC constant current driving units. The each DC / DC constant current driving unit corresponds with a LED load with one kind of power and is used to provide a direct current for the corresponding LED load. In this case, when the LED load of the LED lamp is replaced, the whole driving power supply circuit does not need to be replaced and the DC / DC constant current driving unit corresponding to the LED load is only needed to be configured. Therefore, displacement costs of the LED lamp can be substantially reduced.

Description

technical field [0001] The invention belongs to the field of LED lamps, in particular to an LED street lamp and a driving power supply circuit thereof. Background technique [0002] With the advent of the LED lighting era, LED street lamps will be used more and more widely. LED street lamps mainly include LED loads and driving power circuits for driving LED loads. The existing driving power circuits are a whole circuit. For the LED load, it is necessary to configure different driving power circuits for it. In this way, when the LED load of the LED street lamp is replaced, the entire driving power circuit will also be replaced, which will undoubtedly increase the cost of the LED street lamp. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a driving power supply circuit for LED street lamps, aiming at solving the problem of high cost in replacement of existing LED street lamps. [0004] The embodiment of the present i...
