PROBLEM TO BE SOLVED: To provide a light-emitting diode lamp, in which the number of light emitting diodes to be mounted can be varied so that the brightness is changed according to the number of the mounted light emitting diodes.SOLUTION: A light-emitting diode lamp 100 can mount light-emitting diode units 50 by varying the number of the light-emitting diode units 50. Since the light-emitting diode units 50 exist around a trunk 63 within the range of the light-emitting diode units 50 from 120 degrees to 360 degrees, the brightness is changed within the range at or more than 120 degrees and at or less than 360 degrees in the case where the number of the light emitting diode units 50 mounted changes. |
