Claim Text:
1. A vehicle light unit comprising: a light transmitting portion on a first end of the light unit, a body connected to a second end of the light unit; a detecting member and a light source unit located in the light transmitting portion, the detecting member detecting environment brightness, the light source unit emitting light to compensate light difference between an expected brightness and the environment brightness; a control member located in the body and electrically connected with the detecting member and the light source unit, the control member having a signal magnifying unit, a switching unit and a control unit, the signal magnifying unit receiving and magnifying a light signal from the detecting member, the switching unit switching the light signal from analog signal into digital signal and sending the digital signal to the control unit, the control unit controlling the light source unit to operate, the control unit controlling timing and sequence of the detecting member to detect the environment brightness, when the light source unit is operated to compensate the light difference between the expected brightness and the environment brightness, the detecting member stops to detect the environment brightness, when the detecting member detects light gaps formed by the light source unit, the light source unit emits light to compensate the difference between the expected brightness and the environment brightness; and a power generation hub which is electrically connected with the control unit, the power generation hub connected to a bicycle rim and generates electric power which is delivered to the light source unit via the control unit.
