Abstract: A colored light for the passengers of a passenger transportation means, in particular for the cabin of an aircraft, comprises a plurality of illuminating means, each emitting electromagnetic waves in a narrow-band wavelength range, wherein the wavelength ranges preferably do not overlap each other. Further, the colored light is provided with a drive unit for driving the illuminating means such that a soothing or stimulating effect on the passengers can be achieved via the color sensation of the human eye and the thus triggered (bio-) chemical processes in the body.

Abstract: The light (10), particularly warning light, for a vehicle, such as, for example, an airplane, is provided with at least one light-emitting diode (20) comprising a housing (22) with connecting elements (24) arranged thereon. Further, the light (10) comprises a heat sink (14) with which the housing (22) of the at least one light-emitting diode (20) is in heat-conducting contact. The at least one light-emitting diode (20) is pressed against the heat sink (14) by means of a pressing element (38) while a relative movement transverse to the pressing direction caused by different thermal expansion is maintained.
