LED lamp, LED illumination device, and LED module
An LED lamp provides a strong red color with a natural appearance. The LED lamp is provided with an LED module and a filter. The LED module includes a blue LED with a main emission peak in the 440 nm to 460 nm wavelength band, a green/yellow phosphor that is excited by light emitted by the blue LED, and a red phosphor that is excited by light emitted by at least one of the blue LED and the green/yellow phosphor. The filter reduces the spectral radiation intensity of at least a portion of the 570 nm to 590 nm wavelength band among light emitted by the LED module.
