LED LIGHT EMITTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an LED light emitting device for efficiently and effectively controlling the distribution of light emitted from an LED light emitting element.

SOLUTION: The LED light emitting device includes: a body case 1 having an illumination opening 5, and a polygonal reflective face 7 in which each of angle portions 7a forms a continuous rounded face and an inner peripheral face is tapered to be expanded in diameter toward the illumination opening 5; a substrate 3 mounted on the opposite side to the illumination opening 5 of the body case 1; the LED light emitting element 2 mounted on the substrate 3 and arranged corresponding to the rounded nearly center of the reflective face 7; and a light-transmissive filler 10 filled in the body case 1 to cover the substrate including the LED light emitting element 2.
