| titleOfInvention | Apparatus for illumination with blue, green, yellow, or red light-emitting diodes |
| abstract | The invention relates to a device for illuminating using blue, green, yellow, or red light emitting diodes (LEDs). Said device comprises one or several colored LEDs and a light-scattering cover that is assigned to the LED color, is made of pigmented plastic, and is provided with a basic pigmentation by means of one or several non-fluorescent dyes. The inventive device is characterized in that the light-scattering cover contains at least one fluorescent dye that is chromatically associated with the basic pigmentation in addition to the basic pigmentation, the dye mixture being adjusted such that the light-scattering cover has a minimum reflection of 28 percent at the wavelength at which the LED/s used draw/s a maximum of power. The sum of the difference between the x value of the light-scattering cover and the x value of the LED and the sum of the difference between the y value of the light-scattering cover and the y value of the LED relative to the chromaticity diagram and the color locations of the reflection of the light-scattering cover and the color location of the LED/s used, alternatively amounts to the following: a) for blue LED illumination: sum x is less than 0.03 / sum y is less than 0.05; b) for green LED illumination: sum x is less than 0.05 / sum y is less than 0.08; c) for yellow LED illumination: sum x is less than 0.0025 / sum y is less than 0.02; d) for red LED illumination: sum x is less than 0.03 / sum y is less than 0.003. |
