Low power illuminator

摘要

An illuminating device (320) comprises a light source (400) associated with a lens (510) having an integrally formed reference surface (580) to which the light source (400) is attached. The light source (400) is a linear array (432) of surface mount light-emitting diodes (430) that emit light in a direction parallel to the surface (424) to which they are mounted. The precise location of the light source (400) relative to the lens (510) concentrates the light emitted from the light source (400) onto the object which is to be illuminated, thus reducing the intensity of light required and the power requirement of the light source (400). <IMAGE>
