To provide a light-emitting diode lamp using a light-emitting diode with little power consumption and having a high projection capability with bright illuminance.

The light source has a plurality of light-emitting diodes 3 with their optical axes arranged in nearly in parallel in the same direction, and the lenses 4 are arranged in the vicinity of the focus on the optical axis of each light-emitting diode. From the rear of each light-emitting diode to the lens on each optical axis, parabolic mirrors of outside variant axis of rotation (or cone inside mirrors etc.) envelope there, and thus mixing of light into the other lenses is not brought about, thereby, no virtual images are generated and emission light can be irradiated overlapped on nearly identical points.
