摘要：

This work proposes a light-emitting diode (LED) luminaire for street lighting based on modular drivers. Each module consists of a driver composed by two integrated dc-dc converters. The first one is a buck-boost converter responsible for the power factor correction, and the second is a buck converter that controls the load current. Both of the converters operate in the discontinuous conduction mode of current. In order to make the system robust against failure, each driver supplies an independent set of power LEDs. Thus, in case of failure of one or more drivers, the system is not completely compromised. The design of the electronic drivers is presented. Experimental results of a prototype with rated power of 50W(twomodules of 25 W) are performed in order to show the feasibility of the proposed solution.
