Abstract
A light emitting diode structure including a light emitting unit having a blue LED chip to produce a first light beam, a first light conversion layer disposed on the light emitting unit to convert a part of the first light beam into a second light beam, and a second light conversion layer disposed on the first light conversion layer to convert another part of the first light beam into a third light beam is provided. A remaining part of the first light beam, the second light beam, and the third light beam are superposed to form a working light beam whose spectrum includes a first wave band ranging from 350 nm to 660 nm and a second wave band ranging from 660 nm to 1000 nm. A power of the working light beam in the second wave band is higher than that in the first wave band.
