2. Description of the Related Art Generally, in various industrial fields, for convenience and safety of workers, a work such as lighting a worksite by combining a work or the like with a socket of a fixed or stationary type is often used.

In order to prevent the work lamp from being damaged due to an accidental mistake or an external impact of the worker, and to prevent rainwater or the like from being introduced into the interior of the base to which the work lamp is connected, Etc. have been disclosed.

As shown in Figs. 1 and 2, a conventional working lamp includes a socket 10 in which a base B configured at an upper end portion of a head H of a lamp L is electrically coupled, a socket 10 A lamp shade 20 for releasing the heat of the lamp B base B transferred to the socket 10 through a plurality of the heat dissipation holes 21 formed in a portion where the socket 10 is accommodated, A rainforest skirt 30 which is fastened to cover a plurality of radiating holes 21 on the upper outer side of the lamp shade 20 so as to prevent rainwater from flowing into the plurality of radiating holes 21, An insulating cap 40 for covering the fastening portion of the lamp shade 30 and the lamp shade 20 or fastening the fastening portion to the socket 10 so that the end of the external electric wire OW is hermetically sealed, A protective cover 50 which is fastened to the lower end of the lamp shade 20 to receive the lamp L and protects the lamp L from the outside, And a control unit.

In this case, the head L of the lamp L has a function of a heat sink for dissipating the heat generated by the LED module to the outside, As shown in Fig.

The conventional working lamp has a structure in which a socket 10 is formed inside the lampshade 20 and an external wire OW extending from the outside of the lampshade 20 is connected to the socket 10, The LED lamp is made to emit light through the insertion of the base (B) of the LED lamp.

However, the connection between the socket 10 and the external wire OW in the lamp shade 20 is performed by a complicated process. More specifically, as shown in the registration room 20-0482605, The panel of the connecting end mounting plate is bolted to the side portion, and after the first wire and the second wire are partially inserted into and supported by the wire guide of the connecting end mounting plate, the socket 20 to which the connecting end mounting plate is coupled is connected to the lamp shade 20 and the other ends of the first and second electric wires inserted into the electric wire guide of the connection end mounting plate with a predetermined length are inserted into the openings of the lamp shade 20, In this state, when the socket 20 is inserted toward the hollow portion of the lamp shade 20, the wire guide is brought into close contact with the inner ceiling portion of the opening portion, and the first and second wires Formed on the inner peripheral surface of the opening portion The first and second electric wires are held in contact with each other while covering the guide groove opening portion of the electric wire guide so that the clearance of the first and second electric wires is suppressed; And the insulating cap 40 is configured to cover the entire outer upper surface of the lamp shade 20 after the electric wires connected to the lamp cable are connected.

Thus, according to the conventional working lamp, since the socket 10 is formed in the lamp shade 20 and the base B of the LED lamp is fitted in the socket 10, There is a problem that the electrical connection work of the OW is very complicated and the working efficiency is lowered.

In the case of the LED lamp inserted into the socket 10, the LED module is configured in the head L that provides the function of the heat sink. At this time, a protective cover Since the LED lamp 50 is composed of a single body, it is necessary to replace the entire LED lamp when the LED module is replaced or maintained, and the corresponding cost is increased.

In addition, in the case of the LED lamp, since the bulb is inserted into the socket 10, the volume of the head L, which provides the function of the heat radiating plate, is large enough to be exposed to the outside of the lamp shade 20 Therefore, when the volume of the head L is exposed to the outside of the lamp shade 20 as described above, there is a problem that a malfunction occurs due to rain or a surge voltage due to contact of a metal object or a risk of electric shock is generated.

Therefore, the object of the present invention is to provide a working lamp which can improve the working efficiency by connecting the heat sink and the LED module inside the lamp shade of the working lamp without the configuration of the socket.
