Abstract: An embodiment of a system includes an RF signal source, a first electrode, a second electrode, and a cavity configured to receive an electrodeless bulb. The RF signal source is configured to generate an RF signal. The first electrode is configured to receive the RF signal and to convert the RF signal into electromagnetic energy that is radiated by the first electrode. The cavity is defined by first and second boundaries that are separated by a distance that is less than the wavelength of the RF signal so that the cavity is sub-resonant. The first electrode is physically positioned at the first boundary, and the second electrode is physically positioned at the second boundary. The first electrode, the second electrode, and the cavity form a structure that is configured to capacitively couple the electromagnetic energy into the electrodeless bulb when the electrodeless bulb is positioned within the cavity.

Abstract: A lighting device includes a casing having an inlet that introduces external air at one side and an outlet that discharges the introduced air at the other side. A fan is located within the casing to flow external air from an inlet direction to an outlet direction. An inlet cover blocks at least an upper area of the inlet to prevent external air from being directly introduced into the inlet. An air flow channel communicates the inlet and the outside, and includes two contracting flow channels having a reducing sectional area in an advancing direction of air. The two expanding flow channels communicate with the contracting flow channels and have an increasing sectional area in an advancing direction of air, so that in a connection portion of the contracting flow channel and the expanding flow channel, the advancing direction of air is changed.

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 the maximum intensities of respective intrinsic wavelengths at different wavelengths. A waveguide is configured to guide the microwaves generated by the magnetron to the bulb. A motor is configured to rotate the bulb. A sensor is configured to sense the intensity of light having a specific wavelength emitted from the bulb. A controller is connected to the motor. The controller adjusts the Revolutions Per Minute (RPM) of the bulb based on the intensity of light having the specific wavelength sensed by the sensor. With this arrangement, a Color Rendering Index (CRI) of the plasma lighting system may be adjusted during operation.

Abstract: A lucent crucible of a Lucent Waveguide Microwave Plasma Light Source (LWMPLS) comprising a Light Emitting Resonator (LER) in form of a crucible (1) of fused quartz which has a central void (2) having microwave excitable material (3) within it. In one example, the void is 4 mm in diameter and has a length (L) of 21 mm. The LWMPLS is operated at a power (P) of 280 W and thus with a plasma loading P/L of 133 w/cm and a wall loading of 106 w/cm2. The lamp is thus operated with a high efficiency—in terms of lumens per watt—while having a reasonable lifetime.
