This description relates to optical and electrical designs, architecture and implementation of smart lighting and displays. The optical architecture is based on the single or multiple laser diodes, single or multiple scanning mirrors and single or multiple un-patterned phosphor plates.
As background, conventional displays use white light illumination and array of color filters and addressable Liquid Crystal Display (LCD) pixels on the panels, with pixels being turned on or off with or without light intensity control by addressing electronics. Another type of displays is formed by array of addressable pixels that generate light emission by electroluminescence (Organic Light Emitting Diode—OLED array). Yet another type of display is created by addressable array of deflectable micromirrors that reflect the color sequential, time division multiplexed light selectively to projection optics and a screen. Additionally, another type of color display that does not require the matrix of addressable elements is based on three color light sources and the biaxial scanning mirror that allows formation of images by scanning in two directions while three lasers or other light sources are directly modulated by driving currents. In addition, patterned phosphor plate with red, green and blue array of phosphor pixels can be addressed by laser light incident on scanning mirrors while the light intensities are controlled by laser drivers. Illumination patterns can be viewed directly, or re-imaged with an optical system to a desired surface.
