Abstract
A white light emitting device, including a circuit board; a plurality of light sources mounted on the circuit board, each light source of the plurality of light sources configured to emit monochromatic light; a light converter spaced apart from the circuit board, the light converter configured to convert the monochromatic light emitted from the light sources to white light; and a compensator provided between the circuit board and the light converter, the compensator configured to convert the emitted monochromatic light to white light.
Claims17
A light emitting device comprising:
- a board;
- a plurality of light sources disposed on the board, each light source of the plurality of light sources including a lens and a light emitting diode configured to emit blue light;
- a light converter apart from the board and configured to emit approximately white light in response to the blue light being incident on the light converter;
- and
- a plurality of yellow phosphor members provided on the board to surround the light emitting diode,
- wherein the plurality of yellow phosphor members includes a plurality of first yellow phosphor members arranged at intervals on a circumference of a first circle surrounding the light emitting diode and a plurality of second yellow phosphor members arranged at intervals on a circumference of a second circle surrounding the light emitting diode, and
- wherein each of the plurality of first yellow phosphor members is disposed inside an outermost line of the lens and spaced apart from the lens.
A display apparatus, comprising:
- a display panel;
- and
- a light emitting device configured to emit light on the display panel,
- wherein the light emitting device comprises:
- a board,
- a plurality of light sources disposed on the board, each light source of the plurality of light sources including a lens and a light emitting diode configured to emit blue light,
- a light converter apart from the board and configured to emit approximately white light in response to the blue light being incident on the light converter, and
- a plurality of yellow phosphor members provided on the board to surround the light emitting diode,
- wherein the plurality of yellow phosphor members includes a plurality of first yellow phosphor members arranged at intervals on a circumference of a first circle surrounding the light emitting diode and a plurality of second yellow phosphor members arranged at intervals on a circumference of a second circle surrounding the light emitting diode, and
- wherein each of the plurality of first yellow phosphor members is disposed inside an outermost line of the lens and spaced apart from the lens.
