ELECTRIC BULB TYPE LED LIGHT SOURCE

摘要

PROBLEM TO BE SOLVED: To provide an electric bulb type LED light source capable of optionally setting a directional property at a point of using time in a finally fixed state when the electric bulb type LED light source is connected with a screw type bulb base.

SOLUTION: The electric bulb type LED has a mechanism in which it makes a housing for holding an LED and the bulb base an LED holding portion and a bulb base holding portion rotate in the rotation axis θ direction of the bulb base when a shape of a light emitting part of an LED is an irrotationally symmetric shape in the rotational axis θ direction to the bulb base, or when a plurality of LEDs are arranged in irrotational symmetry to the rotational axis θ direction of the bulb base. By this constitution, when the electric bulb type LED is connected to an apparatus having the screw type base, the directional property at the point of using time in the finally fixed state can be optionally set.
