Description

Floodlight being easily cleaning}

The present invention relates to a light emitter, and more particularly to a light emitter that is easy to clean by being able to easily remove the foreign matter and dust accumulated on the surface of the light emitter.

In general, CPC (Central Position Controller) emitters and width measuring apparatuses are used in the steel mill, paper industry, and textile industry, especially in steel mills when rolling steel strips which are discharged through rolling rollers. It is used to automatically adjust the center of the strip by detecting a phenomenon that the position is oriented to one side, and as shown in FIG. 1, the strip (A) is located above the light emitter 100 having the fluorescent lamp 102 embedded therein. ) To be transported, and to detect the amount of light generated from the fluorescent lamp 102 by the receiver 104 installed in the vertical direction on the top of the transmitter 100 to determine the transport state of the strip. To have.

However, the conventional transmitter has a disadvantage that the scale and foreign matter adhered to the surface of the strip adheres to the surface of the transmitter during transport, which causes the light of the fluorescent lamp to be blocked, thereby reducing the detection performance of the transmitter. When taking it, there is a telescope phenomenon that winds in one direction, and it causes a fatal discontinuity that results in a winding failure.

In addition, until now, the worker has to directly remove foreign substances accumulated in the emitter, so there is a big disadvantage of safety accidents.

Therefore, the scale for accumulating on the surface of the transmitter and the device for removing foreign matters is the Korean Utility Model Publication No. 2001-0001807 the cleaning device of the transmitter, that is, the foreign matter accumulated on the surface of the transmitter, the screw connected to the axis of rotation of the stem motor on the side of the transmitter base lengthwise And the cleaning block is fitted to the screw and reciprocates along the base side of the transmitter. The cleaning means reciprocates the surface of the light emitting lamp protection glass of the projector according to the forward and reverse rotation of the step motor. While having a structure to remove various foreign matters accumulated on the surface, this means that the cleaning means is a device for sweeping the foreign substances while reciprocating the surface of the transmitter, so that the foreign substances that have been wiped out must be cleaned by the operator again. In other words, it only wipes one side of the light-emitting lamp protective glass repeatedly As long as it is used for a long time, the surface of the protective glass gets stuck and thus the light emitting efficiency is reduced.

In addition, the surface of the transmitter, that is, the lamp protection glass is facing upwards, so that foreign matters or scales are introduced between the gaps, and a cleaning device is formed in the upper direction. It is very difficult to disassemble and assemble at the time of assembly, and excessive maintenance time is required.

Therefore, the present invention significantly improves the structure of the conventional floodlight which has a method of sweeping foreign substances while reciprocating the surface of the lamp protection glass of the floodlight, so that the floodlight can always be kept clean, and the repair and lamp replacement are easy, An object of the present invention is to provide an easy-to-clean light emitter to prevent foreign substances from entering the light emitter.

When the present invention is described in detail by the accompanying drawings as follows.

2 is an exploded perspective view for showing the structure of the present invention floodlight (1), the present invention is largely a lamp 70, cylindrical and transparent lamp protection means for embedding and protecting the lamp, and the lamp and the lamp protection tube A lamp support means for supporting, a lamp protection tube driving means for allowing the lamp protection tube to be rotatable, a holding means for holding the lamp support means, and a leather pad 12 in close contact with left and right sides of the lamp protection tube; It consists of the main body 10 provided with the brush 13.

The lamp protection means comprises a lamp protection tube 50 having a transparent cylindrical shape and a cap coupling means at both ends, and a cap 30 coupled to both ends of the lamp protection tube.

The cap coupling means may be composed of a screw portion 51 formed on both ends of the outer periphery of the lamp protection tube 50, in this case, the screw portion must also be formed on the inner periphery of the cap 30 coupled to the lamp protection tube 50. do.

In the present invention, the coupling between the lamp protection tube 50 and the cap 30 is only a method of combining the screw portion 51 formed on one end of the lamp protection tube and the screw portion 32 formed on one end of the cap 30 cap coupling means. Although described as, the combination of the lamp protection tube 50 and the cap 30 may be used in a variety of well-known methods. The lamp protection tube 50 is preferably made of glass or synthetic resin.

The lamp protection tube 50 and the fluorescent lamp 70 embedded in the lamp protection tube are supported by a lamp support means, and the configuration of the lamp support means is as follows.

In other words, the fluorescent lamp 70 is coupled to the socket 21, the socket 21 is interpolated and coupled to the fluorescent lamp fixture 20 having a coupling projection 22 and the fluorescent lamp fixture It consists of a bearing 40 is extrapolated to the outer peripheral surface of the (20).

The coupling protrusion 22 is coupled to a bracket 11 having a holding means for holding the lamp support means formed in the main body 10, that is, the coupling groove 11a.

At this time, the coupling protrusion 22 has a square shape, and the structure is inserted into and coupled to the coupling groove 11a, so that the lamp protection tube 50 functions as a kind of shaft supporting the rotation thereof.

Of course, the coupling protrusion 22 is fixed to the coupling groove so that it does not rotate and only the lamp protection tube is rotated by the bearing 40. This is to prevent the rotation of the fluorescent lamp, so that it is very cumbersome to manufacture and complicated configuration when the fluorescent lamp can be rotated, but it is selected as the most preferred embodiment, the present design is the fluorescent lamp fixture 20 and the lamp protection tube It is also within the scope of the present invention to rotate together, to form a slip ring in the cap, and to supply the power by a brush to the slip ring to emit light.
