A light source having an outer size set equal to the dimension of a straight tubular fluorescent lamp, comprising:
- a straight light emitting tube;
- and
- end caps provided at the opposite end portions of the light emitting tube, wherein each of the end caps includes first pins arranged at the same positions as lamp pins of the fluorescent lamp, the first pins having the same shape as the lamp pins of the fluorescent lamp, and at least one of the end caps includes a current-feeding second pin.
A light source differing from a fluorescent lamp, comprising:
- a light-emitting unit;
- end caps mountable to sockets of an existing illumination device for the fluorescent lamp;
- and
- a current-feeding unit for feeding a lighting current to the light-emitting unit via a current-feeding path detouring the sockets, the current-feeding unit being positioned to face the illumination device when the end caps are mounted to the sockets.
