Abstract
The invention relates to an LED lamp for warm white light having an LED module consisting of at least one color-converted blue or UV LED, and at least one monochromatic LED, preferably a red LED, in the case of which the mixed spectrum produces white light with a color temperature CCT of between 1500K and 2400K, preferably 1700K and 2100K at room temperature, and between 1800K and 2400K, preferably 2100K and 2300K at a stationary operating temperature of, for example, between 70° C. and 80° C. of the LED lamp.
Claims17
LED lamp, having an LED module with at least one color-converted blue or UV LED, and at least one monochromatic red LED, wherein the mixed spectrum of said at least two LEDs is white light with a color temperature of between 1500K and 2400K at room temperature and a color temperature of between 1800K and 2400K at a stationary operating temperature of between 70° C. and 80° C. of the LED lamp, and wherein a primarily yellow-emitting color conversion material is associated with the blue or UV LED to convert light emitted from the blue or UV LED, wherein a second nitride-based red color conversion material is also associated with the blue or UV LED to convert light emitted from the blue or UV LED to a light whose peak wavelength is separated by at least 5 nm from a dominant wavelength of the monochromatic red LED.
LED lamp, having an LED module consisting essentially of at least one color-converted blue or UV LED, and at least one red LED, wherein a mixed spectrum produces white light with a color temperature below 2500K, and in addition to a primary yellow-emitting color conversion material the color conversion material has a further color nitride-based red conversion material with a red emission spectrum whose peak wavelength is separated by at least 5 nm from a dominant wavelength of the red LED, wherein both color conversion materials are associated with the blue or UV LED to convert light emitted from the blue or UV LED.
