  • Patent number: 9303847
    Abstract: A method for producing an LED lamp includes a lamp housing wherein at least one carrier circuit board equipped with LEDs is inserted into the lamp housing in such a way that at least a subregion of the lamp housing protrudes beyond the carrier circuit board with a projection, and the projection is at least partially deformed after insertion in such a way that the lamp housing is pressed with the carrier circuit board.
    Type: Grant

  • Publication number: 20120242241
    Abstract: The present invention relates to a lighting apparatus with at least one LED, in particular an LED retrofit, in which a surge arrester whose breakdown voltage is above the maximum system voltage and below the starting voltage of the fluorescent lamp which is intended to be replaced by a lighting apparatus according to an embodiment. In this way, a lighting apparatus according to an embodiment can be operated using the ballast originally designed for a fluorescent lamp, wherein, moreover, a risk to an operator when inserting a lighting apparatus according to an embodiment into a luminaire can reliably be ruled out.

  • Patent number: 6424512
    Abstract: A circuit arrangement and method for overload protection for a control element is provided, wherein the voltage across a control path of the control element is monitored and utilized as a criterion for shutting off the control element. The actual shutting off of the control element is effected through the aid of a protection circuit that inhibits the control element above a critical current level.
