Lighting systems, devices and techniques are provided to construct solid-state lighting devices and systems that provide energy-efficient illumination, including personal lighting devices, desktop lighting devices, and ceiling/overhead lighting devices based on semiconductor-based solid-state light sources such as LEDs or laser diodes. The disclosed solid-state lighting devices and systems use an illumination plate to receive the generated light from one or more LEDs or laser diodes and to process the received light to exhibit desired spatial distribution of light power across the illumination plate and desired direction of the output light from the illumination plate. |
