摘要:
Provided is a lamp designed to use as a light source a solid-state light emitting device with a simple and inexpensive structure and having an improved heat dissipation performance. A lamp uses a solid-state light emitting device as a light source. A cap is mounted to an external apparatus at the time of use. A housing is made of a translucent material and is connected to the cap. A light-emitting module includes one or a plurality of solid-state light emitting devices and is mounted such that the main-light-emission side (lower side in FIG. 1) thereof is in close contact with the inner wall of the housing. Further, the gap between the housing and the light-emitting module may be filled with a thermal conductive material having a translucency and a thermal conductivity.

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 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.

A light source device is provided such that light emerges mainly from the axially central section of an outer tube and is configured to minimize the risk of thermal damage to electronic components of a circuit unit. The device includes: a semiconductor light-emitting element as a light source; a circuit unit driving the semiconductor light-emitting element to emit light; and an envelope formed from an outer tube and a power connector, the envelope housing the semiconductor light-emitting element and the circuit unit. A light diffuser having a reflective outer surface to diffuse incident light is disposed at least partially in the axially central section of the outer tube. The semiconductor light-emitting element is disposed on a side of the light diffuser at which the power connector is located and in an orientation that its main emission direction points toward the light diffuser.
