Definitions

  • the present invention relates to a lighting apparatus that changes the color temperature of illuminating light taking into account appearance of color.
  • a lighting apparatus that renders the color of a visual object vivid to make the color of the visual object look desirable.
  • a lighting apparatus has been known in which a color gamut area is increased by additive color mixing of light from red, blue, green, and white LEDs, for example, thereby making the color of a visual object illuminated with illuminating light look vivid (refer to Japanese Laid-Open Patent Publication No. 2011-204659 , for example).
  • the FCI is an index indicating the extent of contrast and vividness in color reproduction of a light source, and is defined by the following formula (1):
  • FCI G LAB T G LAB D ⁇ 65 1.5 ⁇ 100
  • G LAB (T) is a color gamut area of a color combination sample for four colors of red, blue, green, and yellow in an LAB color system under a test illuminant
  • G LAB (D65) is a color gamut area of the four-color combination sample in the LAB color system under a standard illuminant D65.
  • the FCI is 100 under the standard illuminant D65, and an illuminant whose FCI is higher than 100 renders the color more vivid and makes the space look brighter, as compared to the standard illuminant D65.
  • a lighting apparatus using the FCI as an index for evaluation there has been known a lighting apparatus in which the types of phosphors used in a discharge lamp and the weight ratio thereof are set so that the FCI of light emitted from the discharge lamp is within a predetermined range (refer to Japanese Patent No. 3040719 , for example). Using this lighting apparatus, it is possible to perform lighting that makes the colors of flowers and green leaves appear more conspicuous.
  • the FCI is lowered as the color temperature increases under a general white light source.
  • the FCI of an incandescent lamp whose correlated color temperature is 2700 K is 123

  • a lighting apparatus has been widely used, which includes a plurality of light sources having different emission colors, and controls the output ratio of the light sources to change the color temperature of illuminating light.
  • simply changing the color temperature of the illuminating light might cause unintended change in desirability of color appearance.

  • a variation width of the color temperature of the illuminating light set by means of the operation unit is 2700 K to 5000 K.
  • the light sources include a light emitting device that emits white light having a relatively high color temperature, a light emitting device that emits white light having a relatively low color temperature, a light emitting device that emits green light, and a light emitting device that emits red light.
