Abstract

The present invention is related to an illumination device capable of producing ambient light and whose structure can be efficiently manufactured and assembled. The illumination device comprises: a substrate electrically connect to a power supply, a plurality of light sources attached to a surface of the substrate, a reflection body with a reflection surface situated a distance from said plurality of light sources, a shell having a diffusion surface situated a distance from said reflection surface. The illumination device may further comprise a housing for receiving and supporting the substrate and the reflection body. The housing is configured to join with the shell and can be further attached to an external device receiving the ambient light. The light emitted from the light sources is reflected by the reflection body to the diffusion member and then radiates outwardly to the surrounding environment of the shell. The reflection surface of the reflection body is inclined at angle relative to the substrate. Said reflection angle formed by the reflection surface and the substrate can be adjusted so that the light is effectively reflected by the reflection surface to the surrounding environment of the device.
