PROBLEM TO BE SOLVED: To provide an LED illuminating lamp allowing safe and simple disposal and capable of prolonging a service life, reducing power consumption, and directing outgoing light in the same direction. SOLUTION: This LED illuminating lamp is provided with a printed wiring board 3 provided in a thin and long pipe 2 and many LED bodies 4 arranged at predetermined intervals along the longitudinal direction on an upper face side of the printed wiring board 3, and a rotation prevention means is provided in port fittings 10, 11 or bushings 8, 9. Consequently, light having comparatively high luminance can be emitted at a low current from the LED bodies 4. It is possible to prevent the adhesion of mercury to the thin and long pipe 2 as is observed in a conventional fluorescent lamp, and the rotation of the LED illuminating lamp 1 can be suppressed by the rotation prevention means. |
