Light emitting diode |
摘要 |
A light emitting diode is disclosed which is small and inexpensive and can emit a variety of intermediate colors of light with a single light emitting element chip and whose current consumption is small. This invention provides a light emitting diode which comprises: a substrate; electrodes formed on the substrate; a light emitting element chip connected to the electrodes and mounted on an upper surface of the substrate; a resin material sealing an upper surface side of the light emitting element chip; and fluorescent particles and coloring particles scatteringly distributed in the resin material. The coloring particles absorb a part of wavelengths of light from the light emitting element chip and a part of wavelengths of light that have been changed by the fluorescent particles.
