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

Abstract: An exemplary air cleaning device includes a roller, a photo-catalyst layer and a light source. The roller includes a base and a plurality of fins installed on the base. The roller is movable to cause an air to flow. The photo-catalyst layer is formed on the fins. The light source is disposed facing toward the roller for irradiating the photo-catalyst layer to cause a photocatalytic reaction thus cleaning the air flowing therethrough.
