Microwave plasma discharge lighting system with adjustable color temperature

摘要

A plasma lighting system includes a magnetron configured to generate microwaves, and a bulb filled with a main dose and an additive dose. The main dose and the additive dose generate light under the influence of microwaves and have maximum intensities of respective intrinsic wavelengths at different wavelengths. A motor is configured to rotate the bulb. A controller is connected to the motor. The controller adjusts the Revolutions Per Minute (RPM) of the bulb to thereby adjust a color temperature of light emitted from the bulb.

1. A plasma lighting system comprising:
a magnetron configured to generate microwaves; a bulb filled with a main dose and an additive dose, wherein the main dose and the additive dose generate light under the influence of microwaves and have maximum intensities of respective intrinsic wavelengths at different wavelengths; a motor configured to rotate the bulb; and a controller connected to the motor, the controller being configured to adjust Revolutions Per Minute (RPM) of the bulb, wherein the boiling point of the main dose differs from the boiling point of the additive dose, and wherein the controller is configured to change the RPM of the bulb to thereby adjust a color temperature of light emitted from the bulb.
