Abstract
A reflection-type light emitting apparatus has an excellent heat radiation property and allows the use of a high-power light emitting element, the minimization of a reduction in radiation efficiency of reflected light, and the focused radiation of high-output light at high efficiency. The apparatus has: a caseof metallic material and with an excellent heat radiation property; a reflection mirror sectionformed fitted to the lower portion of case; a transparent plateto cover the upper surface of case; heat radiation platesof metallic material with excellent heat conductivity and inserted inside the case; an LED elementmounted on the heat radiation plate; lead sectionsA,B fixed through an insulating layerto the heat radiation plateto serve as a power supply member to supply power to the LED element; and a spacerof an insulating material to insulate the lead sectionsA,B from the case
