Abstract: A lighting device improves light distribution uniformity. When a light emitting diode (LED) package module is applied to a straight-tube fluorescent lamp, characteristics of a circular surface light source with the LED may be efficiently embodied by varying a refractive index of a light guide member based on positions of the light guide member.
