Abstract:
1. A wireless remote-controlled searchlight comprising: an electric cable with a plug and three leads to supply power source to the searchlight; a lamp housing constituted by an upper housing and a lower housing with an integrally formed ring gear; a base means for mounting the lamp housing; a lamp means for pivotedly mounting in the lamp housing for vertical movement, which includes a bulb housing with a bulb connected by leads of the electric cable and a vertical gear member integrally formed on the back of the bulb housing; a vertical drive means mounted in the lamp housing for vertically driving the lamp means, which includes a reversible gear motor connected by leads of the electric cable having an output shaft with a pinion means for engaging the vertical gear member of the lamp means; a horizontal drive means mounted in the base means for driving the lamp means and lamp housing in a horizontal plane, which includes a reversible gear motor connected by leads of the electric cable having an output shaft with a pinion means for engaging the ring gear of the lamp housing; a separated portable wireless transmitter adapted to transmit a Power On/Off controlled RF signal, a lamp tilting in vertical direction controlled RF signal or a lamp rotating in a horizontal direction controlled RF signal, the wireless transmitter comprising an on/off switch, a four-way directional control switch, an encoder and a signal transmitting unit; and a hand-held manipulator connected to the electrical cable and positioned outside and away from the lamp housing and the base means, the hand-held manipulator comprising a hand controlled circuit adapted to manually and remotely control tilting or rotating the lamp means or power on/off to the bulb of the lamp means; a four-way directional control switch SW an on/off switch SW a RF receiver installed inside the handheld manipulator to receive the controlled RF signals transmitted from the separate portable wireless transmitter; a MCU to output a power on/off controlling signal, a tilting controlled signal or a rotating controlled signal according to the input corresponding received RF signals from the RF receiver or an executed signal sent from the hand controlled circuit while the on/off switch SW a relay actuated circuit configured such that the leads of the electrical cable connected to the bulb of the lamp means are normally kept in an open circuit state and are put in a closed circuit state only if the power on/off controlling signal is output from the MCU to control the relay actuated circuit; and a motor actuated circuit configured such that the leads of the electrical cable respectively connected to the reversible gear motor of the vertical drive means or the horizontal drive means are normally kept in an open circuit state and are put in a closed circuit state only if either the tilting controlled signal or the rotating controlled signal is output from the MCU or while one of the switches SW
