The invention discloses a reflective LED (Light Emitting Diode) light source. The reflective LED light source consists of a lower radiating positioning frame (1), a condensing LED light source (2), a reflective condensing cover (3), an upper radiating positioning frame (4) and an electrode terminal (5), wherein a peripheral light source side of the light source is crossed with a peripheral edge of the upper radiating positioning frame to form a light source front-mounted radiator; the inner circumference of the light source is crossed with the upper periphery of the lower radiating positioning frame to form a base plate side radiator; the lower periphery of the lower radiating positioning frame is a reflective frame of a geometric shape; the condensing LED light source is reflected by the reflective condensing cover to form a condensed light source. Visible distributed LED condensing light source spots are eliminated, the radiation effect is improved, and the temperature raise is reduced; by using reflective irradiation, infrared radiation and irradiation spots on a reflector can be reduced; the reflective LED light source is widely applied to artworks, museums, exhibition places and explosion protection places and can be manufactured in an industrialized, standardized, serialized and generalized manner.
