Patent number: 11428728Abstract: The invention generally relates to LED lighting fixtures and provides apparatuses and methods for determining the forward voltage of a light emitting diode or light emitting diode array in a light fixture. An example apparatus comprises a boost converter with a user-variable forward bias current, that measures and displays the characteristics of an arbitrary LED load. Example methods according to the invention use a configurable boost converter apparatus in the field to determine the LED characteristics of an arbitrary LED module in a lighting fixture and subsequently display the results to the user. The apparatus can be part of a system that includes a link to a mobile device to transmit operating characteristics of the LED load and retrieve pertinent commercial data.Type: GrantFiled: February 23, 2021Date of Patent: August 30, 2022Assignee: Hatch Transformers, Inc.Inventors: John Fisher, Soufiane Daoudiya
