Wavelength control filter, light emitting device and lighting device using the same |
| abstract |
In a wavelength control filter, high color rendering properties can be obtained, and an increase in color temperature or a decrease in the amount of luminous flux is suppressed. A wavelength control filter includes a base material made of a light-transmitting material and a pigment that controls the wavelength of light transmitted through the base material. The light emitting body 33 emits light having spectral characteristics different from the light transmitted through the base material 31, and the light emission peak wavelength of the light emitting body 33 does not overlap the absorption peak wavelength of the dye 32. According to this configuration, by adding the pigment 32 to the wavelength control filter 3, the light in a specific wavelength region is absorbed, and the emission peak wavelength of the light emitted from the LED light source is emphasized to enhance the color rendering. In addition, by adding the luminous body 33, an increase in color temperature or a decrease in the amount of light flux due to the addition of the dye 32 can be suppressed. [Selection] Figure 2 |
