| titleOfInvention | Improved colour rendering in compact fluorescent lamps |
| abstract | Compact fluorescent lamps (CFLs) are characterized by impaired colour rendering, due to their low illumination capability near the blood-red edge of the visible spectrum. Red light output by a light emitting diode (LED) has a relatively narrow spectral distribution, and LEDs are able to produce red light with reasonable efficiency. Blending the light output of a CFL (10) with a small amount of blood-red light emitted by one or more inexpensive LEDs (12) improves colour rendering, while reducing the overall energy cost of operating the CFL-LED hybrid lamp. |
