Abstract

A white light LED is provided. The white light LED comprises a carrier, and a light emitting device, a second LED chip, and a fluorescent powder which are disposed on the carrier. The light-emitting device comprises a first LED chip and a resistance, which are series connected together, and the first LED chip is suitable for emitting a first color light. In addition, the second LED chip is suitable for emitting a second color light, and the second LED chip is parallel connected with the light-emitting device. The fluorescent powder can receive the second color light, and emits a third color light. The white light LED has lower cost and provides preferable color gamut and color temperature.
