摘要:
The invention relates to a lamp (10, 10') which comprises at least one base (11, 11') for connection to a lamp socket on the lamp and at least one LED element (12). The invention is especially characterized in that the lamp is provided with a plurality of LED elements (12) that are disposed at a distance to the socket and combined to a constructional unit (13, 13').
摘要:
The invention relates to a low-pressure discharge lamp comprising a glass discharge vessel (1) which is substantially tubular in form and which is closed in a gas-tight manner on the ends thereof, a filling consisting of an inert gas mixture and quicksilver, in addition to an optional luminous coating on the inner wall of the discharge vessel (1). Two current supply inlets are respectively melted into the two ends of the discharge vessel (1), with a helical electrode secured thereto (5). The invention is characterized in that in order to increase the switching resistance of the lamp in a cold start operation, at least one other electrode (7,8) made of a conductive material is arranged in the region between the helical electrode (5) and the connecting end of the discharge vessel (1) and one end of said other electrode (7, 8) is electrically connected to one of the two current supply inlets (3, 4).

The invention relates to a lighting system comprising a discharge lamp (5) that is provided with an Hg source (52) from which mercury evaporates when the discharge lamp (5) is operated, and an electronic ballast (4) for operating the discharge lamp (5). The inventive lighting system is characterized by means (7, 8) for detecting temperature values, with the aid of which the actual temperature of the Hg source (51) can be determined. The actual temperature is compared to at least one reference temperature, and the temperature of the Hg source (51) can be adjusted in accordance with said comparison. The invention also relates a method for operating a discharge lamp by means of an electronic ballast.
摘要:
A lamp (10) is disclosed with a single- or double-sided socket, whereby a bulb element (11) is arranged on the at least one socket (12), which surrounds a volume of space (14) and said lamp is provided with at least one LED element (13). According to the invention, an irradiation of the LED light into the bulb element occurs and, as a result of reflection, in particular total reflection, on the defining surfaces (16, 17) of the bulb element a transmission of the LED light within the bulb element occurs.
