Abstract
The invention relates to a LED, and more particularly, to provide a circuit and a modulator to more efficiently drive a LED resulting in improving the matching between power source and LED, lowering LED junction temperature and emitting brighter, richer and more natural colors in a more capacitive way.
Claims22
A modulated LED, comprising:
- a LED having a LED junction;
- and
- an open circuit device having a first terminal and a second terminal separating the first terminal by an open gap,
- wherein the LED and the open circuit device are electrically connected in series, and a distance between the LED junction of the LED and the open gap of the open circuit device is within a Budden distance associated with a modulated power waveform obtained by the modulation of an input electrical power applied across the LED and the open circuit device and a frequency response of the open circuit device driven by the input electrical power to make sure an appreciable tunneling excited by the modulated power waveform takes place at the LED junction.
