Abstract

The invention provides an illumination measuring module which includes a housing and a photo detector. The housing is molded with a plurality of surfaces. Each surface of the housing is affixed with respective side edges of the plurality of the surfaces to form a predetermined shape. Each surface includes an external surface and an inner surface. One surface of the plurality of surfaces is a glass surface. The glass surface transmits illumination collected from an external ambience of the housing to one or more inner surfaces corresponding to the plurality of surfaces. On an inner surface of the glass surface, a plane white sheet is positioned which homogenously scatters illumination collected from the external ambience into the one or more inner surfaces in the housing. The photo detector measures scattered illumination diffused from the one or more inner surfaces corresponding to the plurality of surfaces.
