Abstract: A ship-borne searchlight comprising a lamp housing, a reversible motor installed on the lamp housing, a movable cover pivotally connected to the lamp housing and a lamp mounted on back side of the movable cover, wherein the movable cover has a sector block formed on its back side and a ring gear further formed on lower circumference of the sector block to engage a driving gear inside the lamp housing, so that by controlling the reversible motor the driving gear shall rotate in clockwise or counter clockwise direction to enable a movement of open-up or close-down of the movable cover relative to the lamp housing to vary the direction of light beam of the lamp; particularly, when the ship-borne searchlight is not in use, the lamp shall be kept inside the lamp housing to save space taken up by the searchlight.

Abstract: A wireless remote-controlled searchlight adapted to manual remotely control and wireless remotely control comprises a hand-held manipulator having a hand controlled circuit to manual remotely control the searchlight while a four-way directional control switches and an on/off switch being selectively pressed by hand, a RF receiver particularly installed inside to receive controlled RF signals transmitted from a separated potable wireless transmitter, and a MCU adapted to control a relay actuated circuit and a motor actuated circuit by according to the input corresponding received RF signals from the RF receiver to execute wireless remotely control the searchlight; and the hand-held manipulator is assembled on the position outside and away from the searchlight to get an advantage of being easy to wireless remotely control with great precision.

Abstract: A wireless remote control porch light is installed on outer wall or under the eaves of a building with function of remotely controlling to adjust and vary light beam's direction very suitable for courtyard or door illuminating of the building, which comprises a base seat, a rotation connecting seat, a fixed seat, a rotation driving seat, a movable lamp holder and a waterproof rubber sleeve, wherein the rotation connecting seat comprises a swivel driving device, an axial rotation driving device and a radio signal receiver among which the radio signal receiver can receive RF signal for controlling the swivel driving device to drive the lamp holder to move angularly in forward and backward direction or for controlling the axial rotation driving device to drive the rotation driving seat and the rotation connecting seat to rotate jointly about the axis of the rotation driving seat.
