Abstract
A lighting apparatus includes a base plate, multiple first type LED chips, multiple second type LED chips, a first fluorescent layer and a second fluorescent layer. The first fluorescent layer only covers the first type LED chips. The second fluorescent layer covers both the first type LED chips and the second type LED chips. The first type LED chips integrated with the first fluorescent layer emit a first light. The second type LED chips integrated with the first fluorescent layer and the second fluorescent layer emit a second light. The first light and the second light have more than 30% overlapping.
