Embodiment Construction

[0062] mechanical integration

[0063] figure 1 A sectional view of a first embodiment of an integrated gas discharge lamp 5 is shown. As an integrated gas discharge lamp 5 , which is also referred to below as gas discharge lamp 5 , the gas discharge lamp has ignition and operating electronics integrated in the lamp base of the gas discharge lamp 5 . The integrated gas discharge lamp 5 also no longer has a special lamp connection to the outside, but can be directly connected to a commonly used and widespread power supply network. In one embodiment as a vehicle headlight, the connection of the integrated gas discharge lamp 5 is therefore the usual 12 V power supply of the vehicle circuit. In a further embodiment as a vehicle light, the connection of the integrated gas discharge lamp 5 can also be the future 42 V power supply of a modern vehicle circuit. However, the integrated gas discharge lamp 5 can also be designed for connection to the high-voltage circuit of an electr...

Abstract

The invention relates to an integrated gas discharge lamp, wherein a gas discharge lamp burner and operating electronics for the gas discharge lamp burner are integrated in a lamp, wherein the operating electronics control the power of the gas discharge lamp burner according to the burning time thereof in such a way that the level of the light emission of the integrated gas discharge lamp follows a target value curve (I).

Description

technical field [0001] The invention relates to an integrated gas discharge lamp, in which a gas discharge lamp burner and operating electronics for the gas discharge lamp burner are integrated in the lamp. Background technique [0002] The invention proceeds from an integrated gas discharge lamp of the type according to the independent claim, in which a gas discharge lamp burner and operating electronics for the gas discharge lamp burner are integrated in the lamp. [0003] A method for stabilizing and controlling the photometric behavior of metal halide high-pressure discharge lamps is known from DE 19529460. In this method, photometric data are deduced from the dynamic behavior of the lamp and adjusted to default values ​​by means of corresponding control devices. [0004] However, this method has the disadvantage that complex models are required to calculate the photometric data. Furthermore, a relatively complex circuit arrangement is required in order to obtain suffi...
