  • Optical module and light source
    Patent number: 9897281
    Abstract: An optical module and a light source are provided. The light source includes a circuit board, a plurality of light-emitting element chips, a plurality of total reflection elements, an encapsulant, and a plurality of optical wavelength conversion particles. The light-emitting element chips are disposed on the circuit board. Each of the light-emitting element chips is adapted to emit a light beam. The total reflection elements are disposed on the circuit board. Each of the total reflection elements is configured adjacent to one of the light-emitting element chips, a partial light beam of the light beam emitted by the one of the light-emitting element chips enters the total reflection element, and is transmitted in the total reflection element, and emits out from the total reflection element. The encapsulant covers the light-emitting element chips and the total reflection elements. The optical wavelength conversion particles are distributed in the encapsulant.
