Patent ID: 8118441

Claim:
An LED light, particularly for use as a reading or seat light in vehicles, said LED light comprising: a housing ( 36 ), a plurality of LEDs comprising first LEDs ( 16 ) emitting electromagnetic radiation in a first wavelength range, a drive unit ( 12 ) for activating said first LEDs ( 16 ), and a conversion material ( 24 ) which, when excited by at least a fraction of the electromagnetic radiation of the first LEDs ( 16 ), emits electromagnetic radiation in a conversion wavelength range which is in a visible range of a spectrum and is at least partially different from the first wavelength range, wherein the plurality of LEDs further comprise at least second LEDs ( 18 ) which, for effecting a color shifting of the electromagnetic radiation emitted by the conversion material ( 24 ) upon its excitation by the electromagnetic radiation emitted by the first LEDs ( 16 ), emit electromagnetic radiation in a second wavelength range, the first and second LEDs ( 16 , 18 ), provided as semiconductor components with a common substrate ( 14 ) having arranged above it a layer of the conversion material ( 24 ) with an exit side ( 25 ) facing away from the common substrate ( 14 ), are configured in a manner that space angle regions ( 27 ) of radiation emitted by individual LEDs at least contact each other before the exit side ( 25 ) of said layer of the conversion material ( 24 ), that, by means of the drive unit ( 12 ), the second LEDs ( 18 ) are driven in addition to the first LEDs ( 16 ), the electromagnetic radiation of the second LEDs ( 18 ) being at least partially in the visible range of the spectrum and at least partially different from the wavelength range of the first LEDs ( 16 ) and passing the conversion material ( 24 ) substantially without exciting the same, and the electromagnetic radiation of the second LEDs ( 18 ) additionally exciting the conversion material ( 24 ) to cause the conversion material ( 24 ) to emit electromagnetic radiation whose wavelength range is within or outside the conversion wavelength range.
