Abstract
An infrared receiver includes a shielding member and an infrared detecting member. The shielding member has negative refractive power for diverging incident infrared rays. The infrared detecting member includes a main body formed with a convex surface having positive refractive power and an infrared sensor enclosed in the main body. The infrared sensor receives infrared rays converged by the convex surface, and converts received infrared rays to electrical signals.
