Light emitting device and LED bulb |
| abstract |
PROBLEM TO BE SOLVED: To provide a light emitting device using a white LED light source and an LED light bulb having a dimming / coloring function equivalent to that of an incandescent light bulb. A light emitting device controls lighting of a first white light source that emits a first white light, a second white light source that emits a second white light, and first and second white light sources. It is provided with a lighting circuit for light emission, and emits mixed white light with the first and second white light. Each of the first and second white light sources is a light emitting diode that emits light having an emission peak wavelength in the wavelength range of 370 nm to 420 nm, and five or more types that emit visible light when excited by the light from the light emitting diode. It has a phosphor of. The lighting circuit adjusts the amount of current supplied to each of the first and second white light sources so that the color temperature of the mixed white light becomes lower as the emission intensity of the mixed white light becomes lower. When the color temperature of the mixed white light is 2500 K or more and 3000 K or less, the average color rendering index Ra of the mixed white light is 97 or more. [Selection diagram] Fig. 1 |
