Abstract:
A lighting device comprising: (1;18;22;24;27) at least one lighting means; (2), a power-supply unit (10) for the at least one lighting means; (2), and a cooling body (6) for cooling the at least one lighting means; (2), wherein the at least one lighting means (2) is secured to the cooling body (6) and separated from the power-supply unit (10) by the cooling body (6), and wherein the power-supply unit (10) has an electrically insulating cap (17;19;23;25;29) separating the power-supply unit (10) from the cooling body (6).
Abstract:
In various embodiments, a lamp is provided. The lamp may include at least one light emitting diode; a housing, which comprises at least a first housing part and a second housing part, wherein the first housing part is arranged movably relative to the second housing part; a motion detection sensor for detecting a magnitude of a movement of the first housing part relative to the second housing part; and a radiation modification apparatus for modifying at least one parameter of the radiation emitted by the at least one light emitting diode, the radiation modification apparatus being coupled to the motion detection sensor, the radiation modification apparatus being designed to modify the radiation to be emitted by the at least one light emitting diode depending on the detected magnitude of the movement.
Abstract:
A luminaire is specified with a printed circuit board having at least one light emitting diode, the printed circuit board having a cutout for engaging with a holding element, the cutout positioning the printed circuit board in a fashion locked against rotation with the holding element.
