Abstract: A light-emitting apparatus includes a pedestal, a substrate, an LED, an optical component, and a fastener. The LED is mounted on the substrate, and the substrate includes a first through-hole. The substrate is disposed on the pedestal. The optical component is disposed in the emission direction of light from the LED. The fastener passes through the first through-hole and fastens the optical component to the pedestal. A portion of the pedestal or a portion of the optical component is inserted in the first through-hole.

Abstract: 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.
