Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Although the present invention has been described with reference to the embodiments shown in the drawings, it is to be understood that the present invention is not limited to the technical spirit and essential structure and operation of the present invention.

Lamp driving device for the convenience of access to the construction equipment according to the invention is made as shown in FIG.

The room lamp 50 illuminates the interior of the cab, but lights in response to the power of the battery B being interlocked with the door switch 55 that is turned on by the opening of the cab door or by the conduction of the diode 80. This illuminates the interior of the cab.

The door lamp 60 illuminates the outside of the cab door, and illuminates the outside of the cab door by being powered on by applying the power of the battery B in conjunction with the door lamp relay 65.

The door lamp relay 65 lights the door lamp 60 by turning on its relay as a current flows in its movable coil.

The diode 80 conducts as the door lamp relay 65 is turned on, and turns on the room lamp 50 by flowing a current to the room lamp 50.

The smart key controller 70 wirelessly receives the identification information (ID) of the RF tag 105 included in the corresponding start key 100 when the start key 100 approaches and transmits the received identification information to the start limiting device 90. When the identification information ID is recognized by the limiting device 90 and the engine operation signal is applied or when the start switch IGS is detected to be off, the door lamp relay 65 is turned on for a predetermined time. The door lamp 60 is turned on for the set time and the diode 80 is turned on to turn on the room lamp 50 for the set time.

The ignition key 100 includes an RF tag 105 in which identification information (ID) is stored. When the driver approaches the vehicle with the corresponding ignition key 100, the smart key controller 70 receives the corresponding ignition key ( Receive identification information (ID) stored in the RF tag 105 of 100 and transmits to the start limiting device (90).

When the start limiting device 90 recognizes that the identification information ID transmitted from the smart key controller 70 matches the identification information ID preset in the smart key controller 70, the start limiting device 90 transmits the engine start signal to the smart key controller 70. To be sent).

The smart key controller 70 includes a receiver 71, a controller 72, and a timer relay 73. The receiver 71 wirelessly receives the identification information (ID) stored in the RF tag 105 included in the ignition key 100 and applies the received identification information (ID) to the controller 72. The on / off state information of the start switch IGS is read and applied to the control unit 72.

The control unit 72 transmits the identification information (ID) input from the receiving unit 71 to the start limiting unit 90 so that an engine operation signal is applied from the starting limiting unit 90 or the start switch IGS from the receiving unit 71. When the off state information of the control panel is input, the timer relay 73 is controlled to turn on the timer relay 73.

The timer relay 73 turns on the door lamp relay 65 for a set time under the control of the controller 72. The timer relay 73 includes a relay 74 and a timer 75 therein. The door lamp is maintained by keeping the relay 74 on for a set time by the timer 75 under the control of the controller 72. The current of the battery B is applied to the movable coil of the relay 65 to keep the door lamp relay 65 in the ON state for a set time.

In addition, when the door lamp relay 65 is kept on for the set time by the timer relay 73, the power of the battery B flows to the door lamp 60 so that the door lamp 60 lights up for the set time. In addition, the diode 80 maintains the conduction state for the set time by maintaining the ON state of the door lamp relay 65 so that the power of the battery B flows into the room lamp 50 so that the room lamp 50 is set. Lights up for hours.

Lamp driving device for the convenience of access to construction equipment according to the present invention having the function as described above turns on the lamp as shown in FIG.

First, in a state in which the engine start of construction equipment is turned off (S110), when the driver possesses the ignition key 100 to approach construction equipment to ride on the construction equipment, the receiver 71 of the smart key controller 70 ) Wirelessly receives the identification information (ID) stored in the RF tag 105 of the start key 100 and applies the received identification information (ID) to the control unit 72 (S120).

Then, the control unit 72 of the smart key controller 70 transmits the identification information (ID) input from the receiving unit 71 to the start limiting device 90, and the identification information (ID) by the start limiting device 90. Is detected and the engine operation signal is applied from the start limiting device 90 (S130), by controlling the timer relay 73 to turn on the timer relay 73 for a set time, to the movable coil of the door lamp relay 65 By applying a current to turn on the door lamp relay 65 to turn on the door lamp 60 for a set time, and to conduct the diode 80 to turn on the room lamp 50 for a set time (S140, S150).

Accordingly, the driver possesses the ignition key 100 and approaches to ride the construction equipment, so that the door lamp 60 illuminating the exterior of the cab door and the room lamp 50 illuminating the interior of the cab are automatically turned on for a set time. Due to this, sufficient visibility can be secured at night or in a dark place, so it is convenient to ride on construction equipment.

On the other hand, while the driver operates the construction equipment by operating the engine of the construction equipment (S110), when the engine starting of the construction equipment to turn off the operation of the construction equipment, the receiver 71 of the smart key controller 70 Reads the off state information of the start switch IGS and applies it to the control unit 72 (S160).

In addition, the control unit 72 of the smart key controller 70 controls the timer relay 73 as the off state information of the start switch IGS is input from the receiver 71 to turn on the timer relay 73 for a set time. By applying a current to the movable coil of the door lamp relay 65 to turn on the door lamp relay 65 to turn on the door lamp 60 for a predetermined time and to conduct the diode 80 to conduct the room lamp 50. Lights for a set time (S170, S180).

Therefore, when the driver turns off the start switch (IGS) to get off from the construction equipment, the door lamp 60 illuminating the outside of the cab door and the room lamp 50 illuminating the inside of the cab are automatically turned on for a set time. Due to the sufficient visibility can be secured at night or in a dark place to get off the construction equipment.

As described above, the present invention is to recognize the identification information of the RF tag provided in the ignition key in the state that the engine start of the construction equipment is off, or when turning off the engine start of the construction equipment, the door lamp for illuminating the outside of the cab door and The room lamp that illuminates the interior of the cab automatically lights up for a set period of time, allowing the driver to easily enter and exit the cab at night or in a dark place.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. And such changes are considered to be within the technical scope of the present invention.

The present invention may be usefully applied to the case of providing light for getting on and off in construction equipment such as rollers, payloaders, excavators, and the like. According to the present invention, when the engine start of the construction equipment is turned off, the identification information of the RF tag provided in the ignition key, or when turning off the engine starting of the construction equipment, the door lamp to illuminate the outside of the cab door and the inside of the cab The illuminated room lamp is automatically turned on for a set time, allowing the driver to easily enter and exit the cab at night or in a dark place.
