Abstract
A lamp (1) includes: a light source; a substrate (50) on which the light source is disposed; a housing (10) in which the substrate (50) is disposed; an electric cable (20) connected to the substrate (50), the electric cable (20) extending outward from the housing (10); and a thermally conductive sheet (40) having elasticity, the thermally conductive sheet (40) being sandwiched by a region in which the light source is disposed on the substrate (50) and the housing (10), in which the housing (10) has a recess (16) as a storage space in which the electric cable (20) is housed, at a position overlapping part of the substrate (50) out of the region in which the light source is disposed.
Claims16
A lamp comprising:
- a light source;
- a substrate on which the light source is disposed;
- a housing in which the substrate is disposed;
- an electric cable connected to the substrate, the electric cable extending outward from the housing;
- and
- a thermally conductive sheet having elasticity, the thermally conductive sheet being sandwiched by a region in which the light source is disposed on the substrate and a bottom wall of the housing, wherein
- the bottom wall of the housing has a storage space which is a recess and in which the electric cable is housed, at a position overlapping part of the substrate out of the region in which the light source is disposed.
A lamp comprising:
- a first light source and a second light source;
- a housing in which the first light source and the second light source are disposed;
- an outer cover optically transparent, the outer cover being secured to the housing, the outer cover covering the first light source and the second light source;
- and
- a lens that reduces an angle of divergence of light to be transmitted, wherein
- the outer cover is provided with a diffusion region that diffuses light to be transmitted and a non-diffusion region that inhibits diffusion of light to be transmitted,
- light emitted from the first light source is emitted through the diffusion region, and
- light emitted from the second light source is emitted through the lens and the non-diffusion region.
