The present invention relates to a work lamp (10), and more particularly to a work lamp (10) capable of separating a socket (100) and a fixed base (200) from each other and separating and fastening the same to and from an LED substrate polygonal body (300) When one of the work lamps 10 is arranged to be spaced equidistantly by using the branching section 30 along the main electric wire 20 supplied as one electric wire, In the case where the operation lamp 10 can not be used, only the corresponding operation lamp 10 can be replaced or exchanged. In addition, when the operation of the operation lamp 10 is detected by the sensor inside the operation lamp 10, And the illuminance is weakened when the operation is not sensed for a predetermined period of time. Thus, the area where the worker is working in the workplace is illuminated brightly, and the area without the worker is relatively darkly illuminated, It provides the available actions including reducing (10).

As shown in FIG. 1, the basic structure of the present invention is as shown in FIG. 1, and includes a main wire 20 which is elongated in the longitudinal direction and has terminals, a plug and a connector to supply electric power, And a work lamp 10 which is composed of a branching portion 30 of a "T" shape and spaced apart at equal distances from the branching portion 30.

Both ends of the branched portion 30 may be integrally connected by inserting injection which makes mutual indivisible coupling between the main wires 20 as in the conventional main wire, And the main wires 20 connected to both ends can be connected so as to be separable from each other.

Therefore, the present invention can be applied to both of the types in which the configuration of the branched portion 30 is integrated with the main electric wire 20 or in a separate type, and the effects of the present invention based on the proposed configurations are the same, The differentiation and selection compatibility with the previous technical configuration will be superior.

For example, when the branching section 30 and the socket 100 of the work lamp 10 are configured to be separable from each other, the branching section 30 and the main electric wire 20 may be integrally formed. If the socket 30 and the socket 100 are integrally selected, the branching portion 30 and the main electric wire 20 may be manufactured in a separate type rather than an integral type.

The drawing in Fig. 1 shows an example in which the socket 100 and the branched portion 30 are separated from each other. As shown in the figure, the socket 100 is provided with a branch portion 30, It can be seen that the electromagnetically engaging threaded portion 110 is constituted.

On the other hand, the female screw portion 120 is formed on the inner upper end inner circumferential surface of the socket 100 and screwed to the male screw portion formed on the outer circumferential surface of the end portion of the case 500 described later.

A latch 130 in the form of a hook is disposed at an outer end of the socket 100, that is, an end of the socket 100, which is eccentric from the lower end of the lower end of the socket 100, And it is preferably formed integrally with the socket 100 by injection.

The latch 130 has its own weight when the main wire 20 having a considerable length is disposed inside the work site and the branched portion 30 having an equal spacing along the main wire 20, In consideration of the fact that a substantial load is generated in the main electric wire 20 due to the weight of the main electric wire 20 and the operation light 10 to be fastened to the main electric wire 20, It is preferable that the load received by the main electric wire 20 can be dispersed by being hooked to the topographic material such as a clip or a nail around the work site.

The fixed base member 200 is fixed to the lower surface of the power supply printed board 140 configured to be energized within the socket 100 of the operation lamp 10 and has a structure of being separated from and coupled to the inner circumferential surface of the socket 100 do.

In the LED substrate polyhedron 300, a plurality of heat dissipation holes (not shown in the figure) are formed in each unit substrate 330, and LEDs (not shown) are mounted on the unit substrates 330 of the LED substrate polyhedron 300 So that the heat generated from the heat source 301 can be released.

Meanwhile, the fixed base member 200 is fixedly coupled to the upper inner circumferential surface of the socket 100 and is formed by injection molding with a synthetic resin material. The fixed base member 200 is preferably configured to be fitted and fixed to the inner circumferential surface of the upper end of the socket 100 .

The operation sensor 141 is formed on the side of the power supply printed circuit board 140 which is fixed to the lower surface of the fixed base member 200.

When the worker 10 performs work in a specific area in a state where all of the worker lights 10 are installed within the setting area of the work site along the main electric wire 20, 10 is controlled through a control unit such as a microcomputer not shown so that the illuminance of the operation sensor 141 is brightened. When the operator does not sense any operation within the detection range of the operation sensor 141, It is desirable to be able to perform setting control so that the illuminance of the operation lamp 10 is lowered.
