Patent ID: RE42161

Claim:
An apparatus for supplying regulated voltage d.c. electrical power to an LED array comprising: a rectifier means ( 32 ) having an input and an output, said rectifier means ( 32 ) being responsive to a.c. power at said input for generating rectified d.c. power at said output; a power factor correction converter means ( 38 ) having an input connected to said output of said rectifier means ( 32 ) and an output, said power factor correction converter means ( 38 ) being responsive to said rectified d.c. power at said power factor correction converter means input for generating regulated voltage d.c. power at said power factor correction convener means output; and an LED array ( 12 ) having an input connected to said output of said power factor correction converter means ( 38 ) for receiving said regulated voltage d.c. power to illuminate said LED array ( 12 ).
