LED LAMP WITH MIRROR REFLECTOR

摘要

Disclosed is a LED lamp that has a mirror reflector (18) having a reflective surface shaped like a spheroidal surface, a plurality of LEDs (44, 46, 48, 50, 52) arranged on a plane perpendicular to the optical axis (X) of the mirror reflector (18) within the mirror reflector (18), and a lighting circuit for lighting the plurality of LEDs, wherein the plurality of LEDs are divided into two groups, i.e., a first group consisting of LED (44) which is spaced from the optical axis (X) by a first distance, and a second group consisting of LEDs (46, 48, 50, 52) which are spaced from the optical axis (X) by a second distance larger than the first distance, and the luminous flux of the LED (44) is higher than the luminous flux of the LEDs (46, 48, 50, 52) while the LED lamp is lit by the lighting circuit.
