Abstract:
1. A light emitting diode (LED) lighting device shaped like a fluorescent tube, the LED lighting device comprising: a reflector and a circuit board detachably connected to the reflector along a lengthwise direction of the LED lighting device; a plurality of LED light sources distributed in a row on the circuit board along the lengthwise direction of the LED lighting device; and a light guiding member arranged inside the reflector and comprising a plurality of plates each having a connecting end and an opposite distal end, the connecting ends of the plurality of plates connecting together, and the distal ends of the plurality of plates respectively connected to an inner surface of the reflector; each plate comprising two surfaces, one or two of the surfaces defines a plurality of accentuated portions, one distal end of the plurality of plates defining a light incident surface opposing the LED light sources; wherein after entering the light guiding member from the light incident surface, the light from the LED light sources is reflected between opposite surfaces of each plate of the light guiding member; light reaching the accentuated portions is diffused and exits the light guiding member, finally being transmitted outside through the reflector.
