Abstract: A surface mount LED support with metallic reflective cavity includes a plastic frame member and a metallic frame member, wherein the LED support comprises a metallic reflector member which is constructed into a metallic reflector cup-member having a concave cavity. The metallic reflector member includes a bottom metallic plate and a side metallic plate constructing the concave cavity of the metallic cup-member. The side metallic plate is integrally formed by folding the bottom metallic plate. The metallic reflector cup-member has an inner surface coated with a highly reflective material. The LED support of the present invention has high light extraction efficiency, superior cooling capacity and wide range of use of power.
