Patent ID: 8754585

Claim:
An LED driver for on/off and dimming of LEDs comprising a. a switching LED driver circuit adapted to directly connect to 110 volt AC mains and to rectify said AC current into a regulated low voltage DC output current to drive one or more LEDs; b. a PWM generator including control means to generate a PWM signal with an adjustable duty cycle wherein the LEDs are dimmed by adjustment to the pulse width in the duty cycle; c. a lead between the LED driver circuit and the PWM generator to provide a low voltage DC output to the PWM generator to supply power to the PWM generator; d. an ON/OFF switch for serially connecting said PWM generator to said LED driver circuit to provide said driver circuit with said PWM signal, d.1 wherein said control means comprises analog components and a potentiometer operatively connected to said analog components, said potentiometer is operable by an end user; d.2 said analog components comprising circuitry responsive to the potentiometer adapted to generate a PWM signal with a fixed frequency high enough to avoid eye detectable flickering and with a duty cycle having a modulated pulse width controlled by said potentiometer; d.3 said LED driver circuit being adapted to generate a fixed frequency pulse at a frequency high enough to avoid eye detectable flickering in which the pulse width is modulated proportional to said PWM signal duty cycle to control LED brightness; e. components “a”, “b”, “c”, and “d” being an integrated unit sized small enough to fit within a standard 110 volt AC outlet box.
