VIRTUAL POINT LIGHT SOURCE

摘要

A virtual point light source (10) has a support (12) having an axis (14), a plurality of individual light emitting diodes (16) positioned on the support (12): and an individual optic (18) associated with each of the light emitting diodes (16), each of t he individual optics (18) focusing the light from its associated light emitting diode (16) to a virtual point (20) on the axis (14) at a distance (D) from said support.
