Abstract

To provide an LED bulb which can be easily replaced with a conventional bulb, and is adaptable to a variety of forms by the LED bulb singly.SOLUTION: An LED bulb 10 comprises a power supply plug part 13, a body 12, an LED element accommodated in the body 12, and a lens unit 14. The lens unit 14 comprises: a first lens part 27D having a first incident face into which emission light within a prescribed angle range at a high-emission angle side out of light which is emitted from an LED element is incident, a reflection face for reflecting light which is incident from the first incident face, and a first emission face for annularly emitting light which is reflected at the reflection face; a second lens part having a second incident face into which emission light within a prescribed angle range at a low-emission angle side out of light which is emitted from the LED element is incident, and a second emission face for emitting light which is incident from the second incident face; and a third lens part 26 having a third incident face into which light emitted from the first emission face and the second emission face is incident, and a third emission face which is emitted in a state that light incident to the third incident face is light-focused.SELECTED DRAWING: Figure 2
