Systems and Methods for Converting Alternating Current to Drive Light-Emitting Diodes

摘要

A system and method for converting alternating current from at least two types of electronic ballasts for fluorescent bulbs into direct current for an array of LEDs. The device is assembled such that it can fit into existing fluorescent bulb fixtures. Alternating current from a contemplated electronic ballast can have one of two peak-to-peak voltages and the circuitry of the device will convert either alternating current into approximately the same direct current. In doing so, the array of LEDs is illuminated providing an LED alternative to fluorescent light bulbs.

主权项

1. A lighting device comprising:
a set of light-emitting diodes (LEDs) electrically coupled with each other; and a conversion circuit electrically coupled with the set of light emitting diodes, comprising:
a first circuitry coupled with the set of LEDs and configured to convert an alternating current having a first peak-to-peak voltage into a first direct current and further configured to feed the first direct current into the set of LEDs,a second circuitry coupled to the set of LEDs and configured to convert an alternating current having a second peak-to-peak voltage into a second direct current and further configured to feed the second direct current into the set of LEDs, anda switching circuitry configured to switch an input alternating current between the first circuitry and the second circuitry based on a peak-to-peak voltage of the input alternating current.
