The one end side end portion of the printed circuit board 2a in the short-side direction is fixed to the fixing portion 4a of the outer cover tube 4, and is displayed in the short-side direction of the printed circuit board 2a as shown in FIGS. 2A and 2B. The plurality of light-emitting diodes 3 are mounted on the end surface 2b of the other end side end, the surface 2c along the longitudinal direction, and the three sides of the back surface 2d.

The end surface 2b of the other end side end portion of the printed circuit board 2a in the short-side direction is at least ensured to have a width a in which the mounted light-emitting diodes 3 can be arranged in a row. Each of the light-emitting diodes 3 is connected to the circuit of the direct-current power supply in a row on each of the printed circuit boards 2a. The length of the short side direction (the vertical direction in the drawing) of the printed circuit board 2a is a length from the inner peripheral wall surface of the outer cover tube 4 to the center position of the outer cover tube 4 as shown in Fig. 2B.

As long as the shape of the light-emitting diode 3 is long, as shown in the figure, the longitudinal direction of the light-emitting diode 3 is arranged in parallel along the longitudinal direction of the super wide-angle LED illumination tube 1 and the printed circuit board 2a. Two rows of the light-emitting diodes 3 may be disposed on the front surface 2c and the back surface 2d of the printed circuit board 2a, or may be arranged in a staggered manner. Thereby, the amount of irradiation can be increased, and the irradiation range can also be increased.
