Reconfigurable LED arrays and lighting fixtures

摘要

An optimum regulation method is disclosed for reconfigurable LED arrays used for general illumination applications. This document describes a reconfigurable LED array formed by connecting in series LED lamps and LED pairs capable of being reconfigured in either series or parallel. The performance deficiencies of previous solutions are solved by changing the knee voltage of the array through the reconfiguration of LED pairs. The simplicity of the concept can make practical the implementation of driverless LED lighting fixtures.

1. An LED array used in general illumination applications, the array comprising:
LED groups, the groups being formed in such a way as to allow a current entering the array to also flow through each of said groups; each group comprising a plurality of LEDs capable of reconfiguring the interconnections among the LEDs within said plurality; and, the number of groups forming the array being such that said number makes the non-simultaneous reconfigurations of the groups capable of substantially controlling said current flowing through the array.
