摘要:
A compact open-rated HID lamp (10) having a shrouded arc tube (12) positioned within a compact outer envelope (28), which lamp (10) has an arc tube mounting assembly (30) characterized by a long lead wire (32) which extends from the press seal (29) at the base end (28A) of the outer envelope (28), winds helically around the shroud (26) and extends into and is biased outwardly against the distal end (28B) of the outer envelope (28), thus not only conducting current to the distal electrode (24) of the arc tube (12), but also centering and supporting the retaining shroud (26) and supplementing the shroud's retainment function with minimal parts and minimal wire connections. In addition, arc displacement is minimized, leading to higher lumen maintenance and longer lifetimes.
摘要:
A discharge lamp (11) is described, in particular power supplied with direct current, comprising: a socket (12); a first tubular portion (13) surrounding a first electrode (14) having a first end (14A) and a second end (14B); a bulb (15) made of a transparent material and containing high-pressure gas, the first end (14A) of said first electrode (14) and a first end (ISA) of a second electrode (16); a second tubular portion (17) surrounding said second electrode (16) and extending from the bulb (15) in a direction substantially opposite to said first tubular portion (13). The main feature of the invention consists in the fact that a second end (16B) of said second electrode (16) is connected electrically to said socket (2) through a plurality of wires 18, which are electrically connected in parallel to one another.

[TECHNICAL FIELD] A method and a device for artificially generating and showing an aurora. [PROBLEMS] To generate and change a truc-to-life curtain-shaped discharge light emission by using a simple device. [MEANS FOR SOLVING PROBLEMS] As shown in Fig. 1 , in a pressure-reduced chamber (1), two electrodes (2) are arranged in X direction and an electrode (3) is arranged in Z direction in such a manner that the two electrodes (2) oppose to the electrode (3) and they are apart from each other. A coil (6) generates a magnetic line of force (m) in the z direction. [MAIN USE] Exhibition for public.
摘要:
A high intensity discharge lamp (10) has an envelope (12) having a base end (12a), a middle portion (12b) and domed end (12c) arrayed along an envelope longitudinal axis (14). Two spaced apart electrical lead-ins (34, 36) are sealed in the base end (12a) and extend into the envelope (12). A substantially U-shaped frame (38) is within the envelope (12) and the U-shaped frame comprises glass tubing 26a. A light source (16) has an arc discharge capsule (16b) positioned within the frame (38) and a containment vessel (18) is spaced from and surrounds the arc discharge capsule 16b. The containment vessel (18) comprises a transparent structure (19) attached to the frame (38) and formed to provide multiple, independent, localized fractures capable of absorbing the given kinetic energy possessed by the shards.
摘要:
An electric lamp (100) including a sealed light-transmissive lamp envelope (105) having an interior space, a base fixed to the outer envelope (105), a non-insulated main conductor wire (160) within the outer envelope and connected to the base (110) at one end, a light source (140) capable of generating light within the outer envelope (105), a shroud (145) surrounding the light source (140) and mounted adjacent the non-insulated main conductor wire (160), and a first center support. The light source (140) has first and second ends. The first end is electrically coupled to the non-insulated main conductor wire (160), and the second end is coupled to a stem lead (180). The first center support (150) supports the shroud (145) and the light source (140) and mechanically couples the shroud (145) and the light source (140) to the non-insulated main conductor wire (160).
摘要:
Die Erfindung betrifft eine Hochdruckentladungslampe mit einem zweiseitig abgedichteten Entladungsgefäß (4), das in einem Außenkolben (1) eingeschlossen ist. Zwei Glasrohre (8a, 8b) umgeben das Entladungsgefäß (4) auf seiner gesamten Länge koaxial und dienen als Berstschutz sowie als Wärmestaurohr. Getragen werden die Glasrohre (8a, 8b) mittels zweier Keramikhalter (12), die in die offenen Enden der Glasrohre (8a, 8b) eingreifen und am Lampengestell (9) fixiert sind. Die Keramikhalter sind vorzugsweise kreuz- oder ringförmig mit Steg ausgeführt.
