Title: The Innovative Contributions of David Betts

Introduction

David Betts is a notable inventor based in Peabody, MA, who has made significant contributions to the field of lighting technology. With a total of two patents to his name, Betts has focused on developing advanced lighting solutions that enhance efficiency and performance.

Latest Patents

One of Betts' latest patents is for an LED lamp designed to provide white light through a combination of light sources. This innovative lamp features a plurality of blue light emitting diodes (LEDs) that are covered by domes. The design allows a portion of the blue light to be transmitted while another portion is converted into red light using a phosphor contained within the domes. Additionally, a cover over the light sources transmits red and blue light while also emitting yellow light in response to the blue light. This combination results in white light with a color rendering index (CRI) of at least 80.

Another significant patent by Betts involves solid state light source driving and dimming systems. This technology enables multiple solid state light source driver circuits to be connected to a single AC voltage source. The system includes constant current circuitry to generate a consistent AC current and rectifier circuitry to produce a DC current for driving the LEDs. The dimming control utilizes shunt circuitry that operates with a PWM switch to manage the AC voltage source, improving the overall efficiency of power transfer to the LEDs.
