Abstract
Apparatuses and systems are provided for changing the spectrum of light emission from a light-emitting diode (LED) light set. The LED light set may include LEDs, each of which having at least a first LED chip and a second LED chip configured to emit light at differing wavelengths. The first and second LED chips may be connected in series with opposite polarities. Responsive to receiving a power flow in a first direction from a power terminal, the first LED chip may emit light of a first color while the second LED chip may remain powered off. Responsive to receiving the power flow in a second direction opposite the first direction from the power source, the second LED chip may emit light of a second color different from the first color while the first LED chip may remain powered off.
Claims20
An apparatus comprising:
- a first light-emitting diode chip having a first polarity;
- and
- a second light-emitting diode chip connected in series with the first light-emitting diode chip, the second light-emitting diode chip having a second polarity opposite the first polarity,
- wherein the first light-emitting diode chip is configured to emit light of a first wavelength in response to a power flow in a first direction, and wherein the second light-emitting diode chip is configured to emit light of a second wavelength, different from the first wavelength, in response to the power flow in a second direction opposing the first direction.
An apparatus comprising:
- a first plurality of first light-emitting diode chips, wherein each of the first plurality of first light-emitting diode chips has a first polarity;
- and
- a second plurality of second light-emitting diode chips, wherein each of the second plurality of second light-emitting diode chips has a second polarity opposite the first polarity, wherein each of the second plurality of second light-emitting diode chips is connected in series with at least one of the first plurality of first light-emitting diode chips, and
- wherein each of the first plurality of first light-emitting diode chips is configured to emit light of a first wavelength in response to a power flow in a first direction, and wherein each of the second plurality of second light-emitting diode chips is configured to emit light of a second wavelength, different from the first wavelength, in response to the power flow in a second direction opposing the first direction.
