Abstract

The utility model relates to a control device for work light, which substantially comprises a microprocessor to receive signals from a power source unit and a control switch. As the power source unit transmits signals to the microprocessor, the microprocessor confirms whether the signal is received from the control switch. If the signal is received, the microprocessor judges ON virgule OFF switching quantity of the control switch and duration of power-on state, thus driving more than a group of drive circuits to drive more than a group of luminescent lamps to generate working light source according to the received signals. As for the working light source state, all luminescent lamps, 1 virgule 4, 2 virgule 4 or 3 virgule 4 luminescent lamps can be switched on to emit completely or incompletely luminous light source. Or all luminescent lamps, 1 virgule 4, 2 virgule 4 or 3 virgule 4 luminescent lamps can emit glittery light source to enable its users to select needed light source brightness by themselves according to visual operating environment and save energies.
