(54) LED illuminating apparatus


(57) There is provided an LED illuminating apparatus (10) improved in color performance and decreased in harmful effect of temperature elevation during operation even in the form of a globe-type lamp compatible to conventional screw-in type sockets. The LED illuminating apparatus including an LED light-emitting device (3a) and a base board (3b) having the LED light-emitting device (3a) mounted on one surface thereof is improved, so that main LED light-emitting elements (3A) emitting white light and additional LED light-emitting elements (3C) emitting color light are used in combination, the additional LED light-emitting elements (3C) being covered with optical regulators capable of scattering the color light, such as complex prism (11) composed of a right-angle prism (21).
