    摘要: An exemplary yellow light emitting diode (LED) (10) includes a substrate (11), a LED die (12), a phosphor layer (13) and an encapsulant (14). The LED die (12) is arranged on the substrate (11) and comprises an indium gallium aluminum nitride represented by the formula In x GayAl z N , wherein x+y+z=1, 0≦x≦1, 0≦y≦1 and 0≦z≦1. The phosphor layer (13) is a yttrium aluminum garnet phosphor layer configured on the light path of the LED die (12). The phosphor layer (13) has a thickness of more than 250 micron. The encapsulant (14) covers the LED die (12) and the phosphor layer (13).
