Abstract
An LED illumination module includes a base, a plurality of first LEDs disposed on a top side of the base and a reflecting barrel disposed on the top side of the base. The first LEDs are disposed outside of the reflecting barrel, whereby light generated by the first LEDs is reflected by the reflecting barrel to illuminate a space below a bottom side of the base.
