An LED lamp has an envelope that includes a globe (30) and a case (50), an interior space of the envelope being divided in two by a mount (20) closing an opening of the globe (30), the lamp containing, in a globe (30) side of the interior space, an LED and, in a case (50) side of the interior space, a circuit unit for causing the LED to emit light. The LED is thermally connected to the mount (20), and the mount (20) and the case (50) are joined to the globe (30) such that, during light emission, at least as much heat from the LED is propagated from the mount (20) to the globe (30) as from the mount (20) to the case (50).

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.

A lamp pertaining to the present invention has an envelope including a base. The envelope houses semiconductor light-emitting elements, a circuit unit lighting the semiconductor light-emitting elements, and a light-guiding member. The light-guiding member has a hollow portion, and the circuit unit is housed in the hollow portion. The light-guiding member includes a light-receiving portion and a light-emitting portion connected to the light-receiving portion. The light-guiding member is held within the envelope such that the light-emitting portion faces the semiconductor light-emitting elements.

A lamp 1 includes a semiconductor light-emitting element 12 and a circuit unit 40 housed in an envelope 2. Within an axially central section of an outer tube 30, a wavelength converter 90 that converts wavelengths of incident light is disposed. The semiconductor light-emitting element 12 is disposed in a region at a side of the wavelength converter 90 facing a base 60 and oriented to have the main emission direction away from the base 60. A light guide 80 is disposed between the wavelength converter 90 and the semiconductor light-emitting element 12 and guides emission light of the semiconductor light-emitting element 12 to the wavelength converter 90. At least one component of the circuit unit 40 is disposed in a region at a side of the wavelength converter 90 opposite the semiconductor light-emitting element 12. A reflecting mirror 50 is disposed between the at least one component of the circuit unit 40 and the wavelength guide 90 and reflects at least part of light received from the wavelength converter 90 back toward the wavelength converter 90.
