Abstract:
A composite lens plate is applied in a light emitting diode (LED) lighting device having a plurality of LEDs. The composite lens plate includes a plurality of refractive elements. The refractive elements are one-to-one corresponding to the LEDs and guide light emitted by the corresponding LEDs. Each refractive element has a refractive property. The refractive elements are classified into at least two types of lenses according to the refractive property. Lenses of the same type have substantially the same refractive property, and the refractive property of lenses of one type is different from the refractive property of lenses of another type.
