US 9,000,457 B2 · Multi-dimensional light-emitting device

Abstract

The present application provides a multi-dimensional light-emitting device electrically connected to a power supply system. The multi-dimensional light-emitting device comprises a substrate, a blue light-emitting diode array and one or more phosphor layers. The blue light-emitting diode array, disposed on the substrate, comprises a plurality of blue light-emitting diode chips which are electrically connected. The multi-dimensional light-emitting device comprises a central area and a plurality of peripheral areas, which are arranged around the central area. The phosphor layer covers the central area. When the power supply system provides a high voltage, the central area and the peripheral areas of the multi-dimensional light-emitting device provide a first light and a plurality of second lights, respectively. The first light and the second lights are blended into a mixed light.
