Abstract:
1. An LED device, comprising: a substrate; a plurality of LEDs electrically mounted on the substrate and configured for emitting light of a first wavelength; a first light pervious layer; a reflective plate mounted on the substrate for directing the light of the first wavelength to transmit through the first light pervious layer; a plurality of phosphor particles contained in the first light pervious layer for converting the light of the first wavelength into light of a second wavelength, a thickness of the first light pervious layer gradually decreasing from a center to a periphery thereof; and a plurality of diffusing particles doped in the first light pervious layer for diffusing the light transmitting therethrough; wherein the reflective plate comprises a first end and a second end opposite to the first end, the first end of the reflective plate is mounted on the substrate, the first light pervious layer is mounted on the second end of the reflective plate and covers the LEDs.
