Patent ID: 8439533

Claim:
A reading device for use in a vehicle, comprising: an LED light source comprising a color temperature adjustable between a warm-white color to and a cold-white color and adapted to emit a light, the LED light source comprising: a first high-power LED that emits a warm-white light; a second high-power LED that emits a cold-white light; a third high-power LED that emits a red light; and a fourth high-power LED that emits a LED cyan light of a predetermined color characteristic, wherein color temperatures of the first high-power LED, the second high-power LED, the third high-power LED, and the fourth high-power LED are adapted to determine a color of the light, wherein a color location of the first high-power LED, the second high-power LED, the third high-power LED, and the fourth high-power LED, within a CIE diagram form corner points of a plane figure having at least four sides and angles that includes a Planck curve; a primary optics; and a micro-lens downstream from the primary optics at a predetermined distance adapted to focus the light onto a surface, the micro-lens further adapted to mix a light spectra emitted from the LED light source to generate a substantially white light that approximates thermal radiators and deflects the light onto the surface.
