The separate portable wireless transmitter 90 includes four-way control switches SW1, SW2, SW3, SW4, an on / off switch SW5, an encoder 91, and a signal transmission unit 92.

The portable wireless transmitter 90 is powered by a replaceable internal power supply, such as a 9 volt battery.

When any one of the switches SW1, SW2, SW3, SW4, SW5 of the portable radio transmitter 90 is pressed, an identification code corresponding to RF (radio frequency) signal information is generated from the encoder 91, thereby generating a signal transmission unit ( 92 is transmitted to the surface acoustic wave (SAW).

For example, when the switch SW5 is pressed, the wireless transmitter 90 transmits an RF control signal including a power on / off control RF signal, and when the switch SW3 or SW4 is pressed, the vertical tilt control RF signal of the lamp is transmitted, and the switch SW1 or Press SW2 to transmit the horizontal rotation control RF signal of the lamp.

Therefore, while the vehicle or the boat is stopped, the search light 15 can be remotely controlled by using the radio transmitter 90 at a place away from the vehicle or the boat.

The small manipulation unit 80 is connected by an electric wire 70 and spaced apart from the lamp housing 20 and the base means 30 and is designed for two useful purposes.

First, the small operation unit 80 connects the circuits of the leads 71, 72, 73 of the electric line 70 while receiving 12 volt DC power from a car or boat battery via the plug 75 and the electric line 70. Alternatively, the searchlight 15 can be remotely controlled manually by controlling to block.

Second, the small operation unit 80 receives an RF control signal transmitted from a separate portable radio transmitter 90, for example, a power on / off control RF signal, a lamp vertical tilt control RF signal, a lamp horizontal rotation control RF signal, and the like. Since the receiver 81 is included therein, the circuit of the leads 71, 72, and 73 of the electric line 70 may be controlled to be connected or disconnected by the radio remote control of the portable radio transmitter 90.

In order to achieve the two purposes, the small operation unit 80 is a microcontroller having a four-way control switch (SW1, SW2, SW3, SW4), on / off switch (SW5), RF receiver 81, ROM or EEPROM (MCU) 82, manual control circuit 83, relay enable circuit 84, and motor enable circuit 85.

The RF receiver 81, the microcontroller 82, and the manual control circuit 83 may be provided with a voltage regulator for converting a 12 volt DC power source into a 5 volt DC power source.

The RF receiver 81 is installed inside the small operation unit 80 and receives an identification code and an RF signal transmitted from the wireless transmitter 90 and then transmits the received RF signal to the input port of the microcontroller 82.

The microcontroller 82 may include a central processing unit (CPU), read-on memory (ROM) or electrically erased and programmable read-only memory (EEPROM), random access memory (RAM), input / output control circuits, and associated circuits for the CTC timer. It is an IC component integrated in a chip, and performs specific control functions independently.

Since the ROM or EEPROM of the microcontroller 82 includes the identification code and decoding information of the RF control signal transmitted from the radio transmitter 90 to the receiver 81, the received RF signal and the decoded signal are received when the received identification code is approved. Based on the control signal, a corresponding control signal is output to the relay enable circuit 84, the motor enable circuit 85, or both.

The relay enable circuit 84 normally maintains the lead 71 of the electric wire 70 as a cutoff circuit, but a power on / off control signal is output from the microcontroller 82 to control the relay enable circuit 84. In this case, the lead 71 is formed of a blocking circuit or a connecting circuit.

When the receiver 81 receives the power on / off control RF signal from the radio transmitter 90 by the radio remote control, the relay enable circuit 84 is controlled by the connection circuit by the microcontroller 82 so that the search light 15 can be used. Of the lamp means 40 of the bulb is turned on.

On the contrary, when the relay driving circuit 84 is controlled by the microcontroller 82 as the blocking circuit, the bulb of the lamp means 40 is not turned on.

Similarly, the motor driving circuit 85 normally keeps the leads 72 and 73 of the electric line 70 as the blocking circuit, but the tilt control signal or the tilt control signal from the microcontroller 82 is used to start the motor driving circuit 85. When the rotation control signal is output, the leads 72 and 73 are formed as a connection or blocking circuit.

When the receiver 81 receives the lamp vertical tilt control RF signal or the lamp horizontal rotation control RF signal from the radio transmitter 90 by the radio remote control, the motor driving circuit 85 causes the lead 72 or 73 of the electric line 70 to move. Is maintained as a connection circuit until it becomes a blocking circuit, so that the reversible gear motor 51 of the vertical drive means 50 is activated to move the ramp means 40 vertically or the reversible gear motor of the horizontal drive means 60. 61 is activated to rotate the lamp means 40 horizontally.

By manual remote control, the manual control circuit 83 is used to operate the relay enable circuit 84 and / or the motor enable circuit 85.

By selectively pressing any one of the four-way control switches SW1, SW2, SW3, and SW4 of the small operation unit 80, the motor driving circuit 85 connects the leads 72 or 73 of the electric wire 70 to the connection circuit. And manually drive the ramp means 40 vertically or horizontally.

When the on / off switch SW5 of the small operation unit 80 is pressed, an execution signal is transmitted to the input port of the microcontroller 82 to turn on the light bulb of the lamp means 40 and the microcontroller 82 turns the power on / off. By outputting a control signal to control the relay enable circuit 84, the lead 71 of the electric line 70 is formed as a connection circuit.

When the on / off switch SW5 is pressed again, the microcontroller 82 controls the relay enable circuit 84 to form the lead 71 of the electric line 70 as a cutoff circuit.

The microcontroller 82 may add a learning circuit with a learning function, whereby the identification code may be input to a new wireless transmitter if there is no wireless transmitter 90.

The wireless remote control searchlight 15 according to the present invention has a waterproof cover 29 which is located in front of the lamp means 40 and coupled to the lamp housing 20, and thus is generated due to the vertical rotational movement of the lamp means 40. Can cover the gap being
