Light Emitting Diode (LED) Bulb
First Claim
1. An light-emitting diode (LED) bulb comprising:
- an LED module;
a plurality of LEDs mounted on a surface of the LED module;
a heat dissipating unit having the LED module mounted thereon and configured to dissipate heat generated by the LEDs, the heat dissipating unit comprising a surface; and
a cover configured to externally pass through radiant light from the LEDs and comprising an outer surface at a side adjacent to the heat dissipating unit,wherein the heat dissipating unit and at least a portion of the outer surface of the cover define a heat dissipation path from an interior of the heat dissipating unit to an exterior of the LED bulb, wherein the heat dissipating path is different from a space between the cover and the LEDs.

Abstract
A lighting device may include a substrate attached to one edge side of a radiator and a cover may be attached to cover the substrate. Heat-radiating fins may be provided on the other edge side of the radiator and an air-cooling unit may be rotatably provided inside the heat-radiating fins, thereby enabling freely rotation. In one or more examples, a case storing a circuit part is attached to the other edge side of the radiator and a cap is provided to the case. By the air flow from the air-cooling unit, the heat-radiating fins are caused to be a part of the ventilation path to allow for ventilation of the inside of the radiator.
