Abstract
A lamp capable of suppressing an increase in a temperature of semiconductor light-emitting devices such as LED is provided. The lamp includes an LED module (11) which is a light source, a radiator (14) thermally coupled to the light source, a lighting circuit (13) for turning the lighting source on and is housed in the radiator (14), and a base (12) for supplying power to the lighting circuit (13), and the radiator (14) includes a heat sink (15) covering the lighting circuit (13) and a light source attachment (16) to which the light source is placed. Furthermore, a convex (16b) of an end portion of the light source attachment (16) is fit into a recess (15c) of the heat sink (15).
Claims12
A lamp comprising:
- a light source having a semiconductor light-emitting device;
- a radiator thermally coupled to said light source;
- a lighting circuit for turning said lighting source on, said lighting circuit being housed in said radiator;
- and
- a base for supplying power to said lighting circuit,
- wherein said radiator includes at least a first heat dissipating component covering said lighting circuit and a second heat dissipating component to which said light source is placed, said second heat dissipating component being detachable and made of metal, and
- an end portion of said second heat dissipating component is fit into a recess or protrusion of said first heat dissipating component.
