  • Patent number: 6848819
    Abstract: An LED array surface-mounted on a circuit board and applied to a cooling member, such that any generated heat is optimally eliminated. The cooling member can be in any desired shape so that motor vehicle lights, such as blinkers, can be adapted to the outside contour of the vehicle. For a rotating light, the circuit board can be applied around a cooling member fashioned as a hollow cylindrical member which is adapted to rotate.

  • Patent number: 5278859
    Abstract: A stripline laser includes a housing having two sides. An exit window is disposed at one of the sides for a laser beam traveling in a given direction. Two metal electrodes are mutually spaced apart defining a discharge gap therebetween. At least two mutually parallel bars having very low coefficients of temperature expansion retain two resonator mirrors at a precisely fixed mutual spacing. The electrodes are rigidly joined to the housing and to the bars in the given direction at only one location in a reference plane. The electrodes are secured at another location against motions relative to the housing running perpendicular to the discharge gap. A holder adjustably fastens an inclination of at least one of the mirrors relative to the discharge gap. The bars fix an axial position and an angular position of the at least one adjustable mirror relative to the reference plane. The reference plane is disposed at least approximately midway between the mirrors.
