Abstract
The utility model provides a signal lamp. The signal lamp comprises a light source used for emitting light in at least one color; an instruction receiving module used for receiving input instructions; and a control module used for controlling the light source to be turned on/off according to the instructions. The control module further comprises a voltage measuring unit used for measuring the voltage value of a signal lamp power supply. When the voltage value is lower than a preset voltage value, the control module then cuts off power supply outputs. The control module controls the light source to be turned on/off and further controls the light color switches according to input instructions. The mechanical structures of buttons of the instruction receiving module can be simplified. The physical mechanical loss is thus reduced. The service lifetime of the signal lamp is further prolonged. A circuit can be protected from working in a low-voltage condition through over-diskharge protection. By controlling the working current of the light source, the signal lamp can save power so as to prolong the duration time.
