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 maximum intensities of respective intrinsic wavelengths at different wavelengths, a motor 170 configured to rotate the bulb, and a controller 160 connected to the motor, wherein the controller adjusts Revolutions Per Minute (RPM) of the bulb.
Abstract:
Die vorliegende Erfindung betrifft eine Lichterzeugungseinheit (10), die im Inneren eines Außenkolbens (2) angeordnet ist, für eine elektrodenlose Entladungslampe (1) zur Ultraviolettstrahlungserzeugung sowie eine elektrodenlose Entladungslampe dafür. Die Lichterzeugungseinheit (10) weist ein Entladungsgefäß (3) und eine flache induktive Spulenanordnung (4) auf, die mit dem Entladungsgefäß (3) operativ gekoppelt ist. Dabei ist das Entladungsgefäß (3) in einer ersten Ausdehnungsrichtung (X) und einer zweiten Ausdehnungsrichtung (Y) breiter als in einer dritten Ausdehnungsrichtung (Z). Das Entladungsgefäß (3) weist zumindest eine schlitzförmige Ausnehmung auf, in der die Spulenanordnung (4) angeordnet ist. Dabei teilt die schlitzförmige Ausnehmung das Entladungsgefäß (3) in einen ersten Kammerabschnitt und einen zweiten Kammerabschnitt, wobei zwischen dem ersten Kammerabschnitt und dem zweiten Kammerabschnitt ein Verbindungabschnitt verbleibt. Die Spannungsversorgung (9) versorgt die Spulenanordnung und das Vorschaltgerät (6) mittels eines elektrischen Leiters (7) mit der Spannung, die zum Betrieb der Entladungslampe (1) notwendig ist.
Abstract:
An LER LUWPL source luminaire (1) having a magnetron (2) heat conductingly mounted below a finned heat dissipater (3) with a suspension eye (4). The magnetron is attached to a microwave transition (5) and a lucent crucible (6). An imperforate cover (8) extends down from the heat dissipater and is closed by a transparent screen (9), held to the cover by a moulding (10). The moulding supports a polished-sheet-metal reflector (11) extending back to the lucent crucible, with its reflective surfaces obliquely facing both the crucible and the screen for reflection of light from the crucible out of the luminaire via the screen. The moulding (10) is generally square shaped and the reflector comprises four triangular faces (12), pyramidally arranged, with a square base embodied by a rim (14) supported on the top of the screen (9) above the moulding (10). The faces converge to a virtual apex (15), on the central axis (16) of the lucent crucible. This axis is coincident with the pyramid's normal axis (17) from the apex to the centre of the base. The faces (12) are angled at 45° to the base. The apex is virtual in that the crucible and its backing piece (18) project through an aperture 19 in the reflector, above which the apex would exist if the aperture were not there
Abstract:
Disclosed is a plasma light source automated luminaire (12) employing a plasma microwave powered plasma light source (32) where the microwave generator (40) and its power supply (43) are separated; either both within the head of the luminaire (12), or the power supply (43) outside the head.
Abstract:
An electrodeless lighting device and method for manufacturing the same are provided. The electrodeless lighting device comprising a magnetron; a waveguide; a resonator; and a bulb disposed in the resonator, the bulb being filled with one of: (a) sulfur, an argon (Ar) gas and a carbon-based (C or C2 ) gas, or (b) sulfur, a nitrogen-based (N or N2 ) gas and an oxygen-based (O or O2 ) gas. The method includes inserting a dose into the bulb and heating the bulb containing the dose at a predetermined temperature for a predetermined time.
Abstract:
A discharge lamp (20) for providing visible and/or infrared radiation comprising a stationary light transmitting bulb (21) filled with a composition that emits light when in plasma state, a radiofrequency source (41) having an output terminal (44) radiating a radiofrequency field for ionizing and heating the composition in the bulb to bring it in a plasma state (35), and a dielectric rod (22) aligned with the output terminal and positioned between the output terminal (44) and the bulb (21) acting as dielectric waveguide for the radiofrequency field.
