Abstract
An LED light source includes a carrier, a plurality of LED chips and at least one set of lenses. The carrier has a mounting surface and the LED chips are mounted on the mounting surface. The set of lenses disposed on the carrier includes a first lens and a second lens, and the first lens encapsulates one of the LED chips and a lighting pattern provided from the LED chip encapsulated by the first lens is converted into a first lighting pattern. The second lens encapsulates one of the LED chips and a lighting pattern provided from the LED chip encapsulated by the second lens is converted into a second lighting pattern. The second lighting pattern is different from or compensates the first lighting pattern.
