    Abstract: An omnidirectional semiconductor light emitting device lamp has a light distribution characteristic having a large range similar to that of a general incandescent lamp. The semiconductor light emitting device lamp includes a light emitting device for emitting light in all directions and reflection plates arranged at a front surface and a lateral surface of the light emitting device. The light emitted from the light emitting device is reflected from the reflection plate located at the front side and the reflection plate located at the lateral side and emitted to a rear side of the light emitting device. A reflection film is formed on all exposed portions of a surface of the substrate on which the light emitting device is mounted.

    Abstract: A light source module includes a substrate, a plurality of light emitting devices disposed along a line on the substrate, and a lens. The lens extends in a long-axis direction in which the plurality of light emitting devices are aligned to cover the substrate and the plurality of light emitting devices, and has end sides opened at opposing ends of the lens in the long-axis direction. The lens has a first surface to which light from the plurality of light emitting devices is made incident, and a second surface allowing light made incident through the first surface to be radiated outwardly. The lens has a variable thickness, measured as a distance between the first surface and the second surface, in a cross-section of the lens along a plane orthogonal to the long-axis direction.
