Title: Alejandro Lopez: Innovator in Solid State Lighting
Introduction
Alejandro Lopez is a notable inventor based in Lake Zurich, IL (US). He has made significant contributions to the field of solid state lighting, holding 2 patents that showcase his innovative approach to lighting technology.
Latest Patents
One of his latest patents is titled "Color mixing for solid state lighting using direct AC drives." This invention describes techniques that enable a low-cost light fixture to produce light with a relatively high color rendering index (CRI) across a range of color temperatures. The patent outlines how a rectified AC voltage can be provided to multiple groups of light-emitting diodes (LEDs) that have characteristics related to various color temperatures and a target CRI level. The control of these LED groups is based on a received control signal, allowing for the production of combined light that meets the desired color temperature and CRI level. Additionally, the received control signal can be modified by a modification circuit to enhance the control of the LED groups.
Another significant patent by Lopez is the "Electronic ballast and startup method." This invention includes an electronic ballast connected to a lamp with a filament. The electronic ballast features a timer that generates inverter and preheat control signals. It receives AC power and converts it to DC power, which is then used by a self-oscillating inverter to provide lamp power. The preheat control signal directs the filament preheater to provide filament power when AC power is initially applied, ensuring a smooth startup process for the lamp.
