Abstract:
Illuminating microwave heater, comprising at least one magnetron (1) radiating microwaves in a first chamber (3, 5), impermeable, reflecting and shielding the microwaves; said first chamber (3, 5) being filled with ionized gas and comprising internally at least a second chamber (4), permeable to microwaves, adapted to contain liquid to feed into the radiators (6, 7) and heat absorbing tubes (6B, 7B); said liquid being heated by friction, when radiated by the microwaves; said illuminating microwave heater comprising pipes (6, 7) connected to said at least one second chamber (4) by means of devices (9, 10) adapted to prevent the microwaves from escaping from the first chamber (5); said ionized gas in plasma state when excited by the microwaves being adapted to generate light illuminating said first chamber (3, 5) at least internally.
Abstract:
An article treatment system and method utilizing an air-cooled lamp and having reduced cooling requirement. A power supply responds to a sensor sensing the presence of an article at an article treating location by providing power to an air-cooled lamp, causing the lamp to project radiation onto the article at a radiation level sufficient to effectively treat the article. An air blower blows air onto the lamp, and a blower driver is responsive to the level of the power being provided to the lamp to drive the air blower at a speed blowing air onto the lamp with an air pressure having a non-linear relationship with the power level.
Abstract:
The invention relates to a lamp (1) comprising a light source (2) that can be excited by microwaves to provide illumination and a housing (4) surrounding the light source, said housing having at least one light exit opening (5). A grille structure (6) or labyrinth structure (7) acting as a microwave shield is associated with the light exit opening (5).
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.
Abstract:
The invention relates to a device for producing UV light. Said device provides light from light sources that operate in accordance with different physical principles. The device comprises a chamber having several gas-filled plasma chambers (11, 12), wherein the chamber has at least one area (37, 39) transparent to UV light and/or VUV light. A first group (11) of plasma chambers is filled with an ionizable gas containing mercury and a second group (12) of plasma chambers is filled with a gas that forms excimers when suitably excited.
Abstract:
A plasma lighting system includes a magnetron 110 configured to generate microwaves, a bulb 140 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 the maximum intensities of respective intrinsic wavelengths at different wavelengths L1,L2, a motor 170 configured to rotate the bulb, a sensor 143 configured to sense the intensity of light having a specific wavelength emitted from the bulb, and a controller 160 connected to the motor, wherein the controller adjusts Revolutions Per Minute (RPM) of the bulb based on the intensity of light having the specific wavelength sensed by the sensor.
