Abstract: The present invention relates to a method for manufacturing a linear LED light source, comprising: providing a tubular glass envelope that is open at its proximal end and its distal end; inserting a light source mount assembly comprising one or more LED units into the tubular glass envelope; forming a distal hermetic seal at the distal end such that a distal opening remains at the distal end; forming a proximal hermetic seal at the proximal end such that a proximal opening remains at the proximal end; filling the tubular glass envelope with a gas filling; and sealing the distal and proximal openings to obtain a sealed lamp envelope; wherein a flow of coolant gas through the tubular glass envelope is maintained during the formation of the proximal hermetic seal and/or distal hermetic seal if the light source mount assembly is inserted before the formation of the respective hermetic seal.

Abstract: Reflector lamp, particularly metal halogen vapor reflector lamp, comprising a reflector, which is rotationally symmetric about a central axis and which encloses, together with a cover, a lamp interior and which tapers toward a neck region opposite the cover, wherein a burner comprising a burner space and also pinched seals, which lie diametrically opposite each other on opposing sides of the burner space and through which corresponding supply lines are run, is arranged on the central axis in the lamp interior, wherein a tubular shielding enclosure, which is connected to the burner by means of a spring clip, is provided at least partially surrounding the burner.

Abstract: A method for introducing an accurately dosable amount of mercury into the discharge vessel of a fluorescent lamp, wherein both sides of the discharge vessel are connected to a lamp receptacle; and the discharge vessel is charged with a gas stream via the lamp receptacle and is filled, with a predetermined amount of mercury. During or after dosing the amount of mercury to be introduced, the mercury is brought in a dosed volume in the form of a single, coalescing drop, then the entire amount of mercury to be introduced is transported into the discharge vessel, while still maintaining the previously formed drop. A change-over mechanism guides the gas stream past the drop via a bypass channel and blocks the bypass channel such that while the bypass channel is blocked, the gas stream is guided over the dosed volume and drags the drop along with it into the discharge vessel.

Abstract: A method is proposed for introducing an accurately dosable amount of mercury into the discharge vessel of a lamp, in particular into a straight fluorescent lamp, wherein both sides of the discharge vessel are connected to a lamp receptacle; and the discharge vessel is charged with a gas stream via the lamp receptacle and is filled, moreover, with a predetermined amount of mercury via a mercury introducing channel. Furthermore, it is provided that during or after dosing the amount of mercury to be introduced, the mercury is brought in a dosed volume in the form of a single, coalescing drop, and then in a fill step the entire amount of mercury to be introduced is transported into the discharge vessel, while still maintaining the previously formed drop.

Abstract: A combined cermet rod and electrode unit for use in a high pressure discharge lamp comprising a cermet rod for connection at its distal end to an electrode tip of the high pressure discharge lamp, and a current supply electrode for forming an electrical connection with the cermet rod. The current supply electrode is formed with a hollow tubular section which is positioned around a proximal end of the cermet rod in physical and electrical contact therewith.

Abstract: A reflector lamp having a concave reflector with a base at one end and a lens at an opposite end. A discharge lamp having a fill of or forming salts maintained by heat in a vapor phase is located near the base end of the reflector. When the reflector lamp is oriented in a near-horizontal position, the fill coming into contact with a colder, lower side of the discharge lamp partially condenses, coloring light passing through the condensate. At least two interior reflector surface areas, which have contours defined by rotating generatrices with configurations of conic section lines, reflect the colored light to distribute it evenly over a surface being illuminated and avoid creating a hot spot.

Abstract: In a metal halide vapor lamp, particularly for application in aquaria, having a fill containing GdBr3, HoJ3, DyJ3, CsJ and TlJ, the fill additionally contains InJ, whereby all the said ingredients are mixed with each other in such a ratio that on the CIE chromaticity diagram the color point of the lamp having the coordinates X=0.265 and Y=0.265 deviates in no direction for more than 7 SDMC.

Abstract: A lamp is made up a reflector, a base and a cover connected along their circumferences defining an inner cavity enclosing an arc tube coaxially oriented within the cavity and mounted to the base. A shroud surrounds the arc tube and is cemented to the base. An anti-glare cap and a clamping element is arranged between an end region on the side of the cover and the anti-glare cap affixed to the shroud via a clamping element.
