Illumination light source and illumination device

The invention discloses an illumination light source and an illumination device. The electric member provided by the invention is effectively contained in the illumination source and the illumination device in order to curb the reducction of the effect of the light source expansion. The stright-shaped LED lamp has: a thin ling frame body (30), a power supply lamp holder (40) covering the end of the long direction of the frame body, the LED member (12) configured inside the frame body, and a circuit substrate containing the first circuit component (22a) and the second circuit component (22d); the circuit member is used for providing power to the LED member; the circuit substrate has the first area (23) covered by the frame body and the power supply lamp and a second area (24) which is covered by the power supply holder. The first circuit element is set in the first area, the second circuit element is set in the second area, the first circuit element from the height of the substrate is lower than the height of the second circuit component.
