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.
Abstract:
An illumination device comprising at least one reflector and at least one light generating unit, wherein the at least one reflector is designed and arranged to reflect at least a portion of a light emitted by the at least one light generating unit into a spatial region that cannot be directly irradiated thereby, and the at least one light generating unit comprises at least one illuminating region having a substantially uniform emission characteristic in a circumferential direction of the illumination device.
