摘要:
A dielectric barrier discharge lamp (1) is disclosed, which comprises a discharge vessel (2) having a principal axis (6). The discharge vessel (2) encloses a discharge volume filled with a discharge gas. The discharge vessel (2) further comprises end portions intersected by the principal axis (6). At least one electrode (3) of a first type and at least one electrode (4) of a second type are used in the lamp (1). The electrodes of one type are energized to act as a cathode and the electrodes of other type are energized to act as an anode. The electrodes are substantially straight, elongated electrodes (3,4) with a longitudinal axis substantially parallel to the principal axis (6) of the discharge vessel (2). At least one of the electrodes (3,4) is positioned within the discharge volume, and the electrodes (3) of at least one type are isolated from the discharge volume by a dielectric layer (5). At least one of the electrodes (4) inside the discharge volume is provided with an outer luminescent layer (12). Additionally, at least one of the electrodes (4) inside the discharge volume provided with a luminescent layer (12) may have a reflective layer (11) under the luminescent layer (12).
摘要:
Bei der erfindungsgemäßen dielektrischen Barriere-Entladungslampen sind die länglichen, z.B. streifen- oder linienförmigen Elektroden in Längsrichtung jeweils durch eine Lücke (16) in zwei Teilelektroden (14a,14b;15a,15b) getrennt. Dadurch wird gezielt die Möglichkeit eröffnet, den einen Teil (14a,15a) der Teilelektroden separat von dem anderen Teil (14b,15b) betreiben zu können und folglich entweder nur einen Teil der Lampe zum Leuchten zu bringen oder die gesamte Lampe. Dazu ist der eine Teil (14a,15a) der Teilelektroden mit einem ersten Betriebsgerät (22) verbunden, der andere Teil (14b,15b) mit einem zweiten Betriebsgerät (21).
摘要:
The lamp circuit includes a power supply, a main switch, and a light and control circuit all serially connected, the light and control circuit comprising the following elements connected in parallel:a) a first light-producing element capable of producing light of a first type and serially connected to a first switch member;b) a second light-producing element capable of producing light of a second type and serially connected to a second switch member; andc) a control circuit member selectively commanding either one of the first switch member, the second switch member and both the first and second switch members to be closed upon the main switch closing the lamp circuit, the first and second switch members remaining opened if not commanded otherwise by the control circuit member.
摘要:
A lamp (100) having an enclosure with partitions (112) has channel segments and/or multiple directions for an electrical arc to travel. The channel segments can be implemented by adding additional electrodes (120) in a channel formed by the partitions, by forming a channel where the arc may travel in multiple directions, or by a combination of the methods. The channel segments and multiple directions of arc travel tend to reduce the voltage required to start the lamp (100).

There is provided a cold cathode fluorescent lamp (50) including a transparent tube (35) having first and second light-emitting areas (37a,37b) defined by partitioning an inner space of the transparent tube at the center, first and second terminal electrodes (31,34) positioned in the first and secon d light-emitting areas, respectively, first and second intermediate electrodes (32,33) positioned in the first and second light-emitting areas, and facing the first and second terminal electrodes, respectively, first and second lead-in wires (36a,36b) connected to the first and second terminal electrodes, respectively, and lead-in wires (36c,36d) connected to the first and second intermediate electrodes. The above-mentioned cold cathode fluorescent lamp makes it possible to lower a break-down voltage and a discharge voltage down to about halves of them in a conventional fluorescent lamp, and hence, discharged electrons are not attracted to a metal part.
