Abstract:
In various embodiments, a lighting device may include: a light-emitting optoelectronic component; an envelope bulb, within which the component is arranged; and scattering means that scatter diffusely, wherein the scattering means are arranged in such a way that, as viewed in a sectional plane which includes a principal ray of the light emitted by the component, light emitted along rays tilted relative to the principal ray is scattered to a greater extent as the tilting angle between ray and principal ray decreases, and this increase in the scattering is fulfilled in a continuous angular range of at least 30°.
Abstract:
In various embodiments, a lighting device is provided. The lighting device may include an air channel, which extends in an axial direction and which has at least one first opening in the region of a first axial end of the air channel and which has at least one second opening in the region of a second axial end of the air channel; at least one radiation arrangement, which emits electromagnetic radiation and which is arranged on an outer side of the air channel such that it emits the electromagnetic radiation in a direction away from the air channel; and at least one conversion element, which comprises phosphors and which is arranged around the air channel and the radiation arrangement at a predefined distance from the radiation arrangement such that the electromagnetic radiation impinges on the conversion element and excites the phosphors in the conversion element for emitting conversion radiation.
