Abstract
A lamp includes a semiconductor light-emitting element, a light guiding element, a wavelength converter, a reflecting mirror, and a circuit unit axially disposed within a central section of the outer tube of an envelope. Light emitted by the semiconductor light-emitting element is guided by the light guiding element to be incident on and be converted by the wavelength converter. At least one component of the circuit unit is disposed at a side of the wavelength converter opposite the semiconductor light-emitting element. The reflecting mirror is disposed between the at least one component of the circuit unit and the wavelength converter, and reflects at least part of light received from the wavelength converter back toward the wavelength converter.
