Abstract
The utility model discloses a wide-angle light-emitting diode (LED) fluorescent tube. The wide-angle LED fluorescent tube comprises a fluorescent tube body and an LED strip-shaped light source. The fluorescent tube body is of a hollow cylinder shape and comprises a shell and an optical fluorescent shade which are installed in a mutually buckling mode. Both the shell and the optical fluorescent shade are of a hollow cylinder structure. The LED strip-shaped light source is arranged in the fluorescent tube body and installed on one side face, facing the optical fluorescent cover, of the shell, and a lighting face of the LED strip-shaped light source faces the optical fluorescent cover. The outer surface of the optical fluorescent shade is of an arc shape. The radian of the arc shaped is larger than a half circle. The outer surface of the optical fluorescent shade is of an arc shaped. The radian of the arc shaped is smaller than a haft circle. Due to the fact that the outer surface of the optical fluorescent shade is of an arc shape, the radian of the arc shaped is larger than a half circle, and the outer surface of the optical fluorescent shade is of an arc shaped, the radian of the arc shape is smaller than a haft circle, light permeability area of the optical fluorescent shade is larger than 180 degrees, lighting angle of the LED fluorescent tube is increased, irradiating range is expanded, light use ratio of the LED fluorescent tube is improved, and then overall lighting effect of the LED fluorescent tube is excellent.
