Abstract:
A plasma lighting system includes a magnetron configured to generate microwaves, and a bulb in which a dose for generation of light using the microwaves and at least one metallic material for generation of thermal electrons are received. The metallic material reduces an electric field intensity required for electric discharge by discharging thermal electrons. In this way, the plasma lighting system reduces the time it takes to turn the light back on after the light is turned off.
Abstract:
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.
Abstract:
A lighting apparatus is provided that includes a magnetron configured to generate microwaves having a predetermined frequency, a waveguide including a first wave guide space configured to introduce and guide the microwaves and a second wave guide space expanded from the first wave guide space, a resonator to which the microwaves are transmitted from the waveguide and a bulb located in the resonator, the bulb encapsulating a light emitting material and being configured to emit light in response to the transmitted microwaves. The second wave guide space is located in a transmission path of the microwaves transmitted from the magnetron to the resonator.

Abstract:
A refrigerator includes a cabinet defining a first storage compartment and a second storage compartment that is positioned vertically below the first storage compartment, a first mullion that partitions the first storage compartment from the second storage compartment, an access cover configured to open or close the access hole, a reception drawer configured to be received into the second storage compartment and including a reception door configured to open and close the second storage compartment and a reception box provided in a rear surface of the reception door, and a cover member configured to cover at least a portion of a top surface of the reception box. The first mullion defines an access hole that allows fluid communication between the first storage compartment and the second storage compartment.
