A method for producing a primary winding for producing an electrode for discharge lamps includes: producing a primary winding, wherein producing the primary winding comprises: providing a primary core wire, which has a longitudinal axis and consists of an electrically conductive material, winding a cladding wire around the primary core wire along the longitudinal axis of the primary core wire, with the result that the cladding wire forms a primary core wire cladding surrounding the primary core wire, and winding a wrapping wire around the primary core wire cladding at a radial distance from the primary core wire along the longitudinal axis of the primary core wire.
摘要:
A low-pressure discharge lamp having a discharge vessel which delimits a gas-tight fill chamber containing a filling gas, wherein the side of the discharge vessel facing the fill chamber is coated at least partially with a luminescent phosphor mixture by means of which electromagnetic radiation in the non-visible range can be transferred into the visible range. A low-pressure discharge lamp which is energy-saving and at the same time possesses good efficiency is provided in that primarily argon is used as the filling gas and that the average particle size of the luminescent phosphor mixture is greater than 5 m.
摘要:
A method for operating a discharge lamp (1), wherein, during operation of the discharge lamp (1), an electrical heating current (IH) and an electrical discharge current (Id) are supplied at least temporarily to an electrode (6, 7). During undimmed operation of the discharge lamp (1), the value (SoS1, SoS2) of the sum of the squares of the electrical currents (I1, I2) supplied via power supply lines (8, 9, 10, 11) connected to an electrode (6, 7) is set in an interval of between 1.2 times the square of a test current (IT) predetermined for the discharge lamp (1) and 2 times the square of this test current (IT)
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).
摘要:
The compact low-pressure discharge lamp (1) has a wound tubular discharge vessel (2) with at least four straight tubes (6, 7) which are in a polygonal arrangement and, close to or at the ends of the straight tubes (6, 7), are connected by transverse connections (8, 10, 11) to form a single continuous discharge path which is closed off in a gastight manner. A coil spring (14) made from metal, which runs parallel to the tubes (6, 7) is arranged in the center of the cylindrical cavity (13) formed by the straight tubes (6, 7) of the discharge vessel (2). The coil spring (14) reduces the firing voltage required.
摘要:
A low-pressure discharge lamp is described having a base housing (10), a discharge vessel (2), whose end sections are fixed to an end section of the base housing, and a contact-making system for making electrical contact with the lamp, which is located on the end section of the base housing (10) which is remote from the discharge vessel, a conductive section (5) being provided, which is electrically connected to the contact-making system and is arranged adjacent to the discharge vessel (2) in the base housing (10) in such a way that an electrical short circuit is formed around the discharge vessel (2). This makes it possible to reduce the starting voltage of the lamp. As an alternative, or in addition, to this, the cross section of the web attachments is increased, which also increases the rate of the luminous-flux run-up.
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). 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.
