Abstract
A multichip light-emitting diode (LED) includes a reflective cup, a plurality of light-emitting chips and a package. The light-emitting chips are disposed in the reflective cup and emit light when driven. The package is disposed in the reflective cup and covers the light-emitting chips. The package further has a plurality of lenses corresponding to the light-emitting chips one by one. The lenses refract light emitted by the corresponding light-emitting chips, respectively. An extrinsic light efficiency of the multichip is increased through the design of the multichip LED.
