The LED lighting tube has the same overall shape as the straight tube type fluorescent lamp, and a metal cover is attached to both ends of the tube body, and protrudes to form a terminal for connecting to the appliance. According to the above configuration, the LED lighting tube can be installed not only in the newly installed fluorescent lamp device but also in the existing fluorescent lamp device, and can receive the power supply from the LED light source to emit the LED inside the tube. As an invention of such a straight-tube type LED lighting tube, for example, Patent Document 1 discloses an LED lighting tube including a cylindrical tubular body made of polycarbonate and attached to a portion provided around the tubular body. An aluminum heat sink having an opening and a plurality of LEDs mounted in the tube. Further, Patent Document 2 discloses an LED lighting tube which is formed of a semi-transparent sleeve and a heat dissipating plate having a holding portion coupled to the sleeve to form an annular structure having an internal cavity, and includes: a circuit substrate The heat-conductive layer is fixed to the holding portion of the heat dissipation plate; one or more LED light sources are attached to the circuit board; and two end covers are fitted to both ends of the tubular structure in a matching manner. In Patent Document 2, it can be attached to a fluorescent lamp device instead of the conventional fluorescent lamp, and can be uniformly irradiated at a wide angle.

Specifically, it is preferable to perform, for example, silver plating, silver coating, chrome plating, or the like on the condensing reflection surface 19a. Moreover, the illuminance at this time is determined based on the law of brightness of light in which "the brightness is inversely proportional to the square of the distance from the light source to the illuminated surface". Preferably, when the light emitted from the LED element is irradiated to the outside of the tube through the total light beam transmitting plate 31 via the first light reflecting member 191, the light is blocked by the light reflecting surface 193a of the second light reflecting member 193.
