Abstract
An LED module includes an LED unit having an LED chip, a lens covering the LED chip, and a diffusing film. The lens includes a light-incident face facing the LED chip, a light-emitting face opposite to the light-incident face, and a connecting face connecting the light-incident face to the light-emitting face. The diffusing film has a plurality of macromolecule diffusing particles mixed therein, and is coated on the light-emitting face of the lens.
