摘要:
In the case of a quiet discharge lamp, support elements for supporting a top plate are provided, by comparison with a base plate, in larger numbers and in an alternating arrangement with individual discharge structures.
摘要:
The invention relates to a silent discharge lamp in which support elements for supporting a top plate opposite a base plate are designed as a unipartite component of the top plate and have a tapering contour.
摘要:
The invention relates to a flat reflector lamp for dielectrically inhibited discharges (14). Greater configuration flexibility is achieved in electrode design (11, 12) while simultaneously ensuring stability of the discharge vessel (1, 2) and preserving the possibility of minimum light reflection impairment by mounting the spacers (3) separated from the flat reflector frames (15) between the base plate (1) and the cover plate (2), the latter being arranged between the electrode strips (11, 12).
摘要:
A description is given of a method for dimming discharge lamps with dielectrically impeded discharges. A continuous or discontinuous power control can be effected by influencing an electric parameter of a pulsed active-power supply and by means of a suitable electrode structure.
摘要:
A description is given of an operating method for a discharge lamp with dielectrically impeded discharges and also a corresponding ballast and illumination system. The invention is directed at withdrawing the external lamp voltage across the discharge lamp in order to produce a back ignition in the lamp by virtue of an internal counterpolarization. The back ignition improves the efficiency of the lamp operation and makes it possible to construct a very small, lightweight ballast.
摘要:
What is described is a flat signal lamp with dielectrically impaired discharge, which is intended in particular for use in traffic signals, above all traffic lights.
摘要:
A discharge lamp (1) including a tubular discharge vessel (2), filled with inert gas and, optionally, a fluorescent layer, having at least three elongated electrodes (3, 4, 5) arranged parallel to the longitudinal axis of the tubular discharge vessel (2). The electrodes are arranged in such a manner that the relationship s a ≥ 0.1 is satisfied, wherein s is the maximum spacing between an imaginary connecting line of an electrode pair and the most closely neighboring point on the wall of the tubular discharge vessel, and a is the mutual spacing between the electrodes of such electrode pair. A higher luminous density is achieved in this way. The lamp is particularly advantageous for a pulsed, dielectrically impeded discharge.

A description is given of a fluorescent lamp having spacers 6 for supporting a wall 2 of the discharge vessel, the fluorescent layer 3 having (8) a reduced thickness in a surrounding region of the spacer 6.
摘要:
A gas discharge lamp having a discharge vessel (202) which is at least partially transparent and filled with a gas filling, a number of essentially strip-shaped anodes (205, 206) and cathodes (203, 204) which extend on the walls of the discharge vessel and essentially parallel to each other, and a dielectric layer (215) between at least the anodes and the gas filling for a dielectrically impeded discharge in the discharge vessel between neighboring anodes and cathodes, characterized in that at least one anode pair (205) is arranged between two cathodes (203, 204) respectively adjacent to one anode pair.
摘要:
A flat radiator (4), suitable for a dielectrically impeded discharge and with a discharge vessel (5) made from an electrically non-conducting material has strip-like electrodes (6, 7) arranged on the wall of the discharge vessel (5), cathodes (6) and anodes (7a) being arranged alternately next to one another, and at least the anodes being separated from the interior of the discharge vessel (5) by a dielectric material (10). In each case one additional anode (7b) is arranged between neighbouring cathodes (6), that is to say in each case one anode pair (7a, 7b) is arranged between the neighbouring cathodes (6). The result is a uniform discharge structure accompanied by optimum utilization of the discharge vessel. FIG. 3b
