摘要:
A substrate having a mounting surface on which an LED is mounted, including: a conductive member provided on the mounting surface and including an electrode and wiring which are electrically connected to the LED; a fitting portion to which a metal body is fitted; and a discharge-reducing portion provided between the conductive member and the fitting portion and having a face tilted with respect to a surface of the mounting substrate, thereby increasing a creeping distance between the conductive member and the fitting portion compared to the case where the discharge-reducing portion is not provided.

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.

A mounting board is provided which is translucent and has a surface on which an LED is mounted. The mounting board includes a sintered body film having a wavelength shifter which converts a wavelength of light and a sintering binder made of an inorganic material. The wavelength shifter converts a wavelength of light proceeding toward the surface on which the LED is mounted among light emitted by the LED and radiates wavelength-converted light. The sintering binder transmits the light emitted by the LED and the wavelength-converted light.
