PURPOSE: A wireless control device is provided to easily change a position of a light unit by vertically moving the light unit along a sawtooth rail. CONSTITUTION: A sawtooth rail is vertically formed on the outer side of a street light. A light unit includes a rail gear, a rotary motor, a casing(210), and a plurality of LED lamps(220). A rail gear is engaged with the sawtooth rail. The light unit moves along the vertical direction of the streetlight. A control switch determines the movement direction of the light unit. A transformer(400) converts the voltage applied through a streetlight cable(10). An LED controller controls the color of the LED lamp. A transmitter transmits the signal of the LED controller to the light unit by wireless. |
