By the configuration of the variable resistor 190 there is an advantage that can adjust the brightness of the LED lamp in stages.

The following describes the operation of the removable LED lamp for a dental unit chair according to an embodiment of the present invention having the configuration as described above.

First, the operation of assembling the product will be described.

The barrel 120 is prepared and the LED substrate 130 having the heat sink 170 is inserted into and installed in the first locking step 126 of the barrel.

After the optical guide 140 and the lenses 150 and 150 'are inserted into the detachable ring 160, the detachable ring 160 into which the optical guide 140 and the lenses 150 and 150' are fitted is screwed into the barrel. It is screwed into the groove 127 and installed inside the barrel.

Next, the snap ring 180 is inserted into the incision slit 121 and provided in the barrel 120. At this time, since the head portion 180a of the snap ring 180 is in a retracted state, as shown in FIGS. 3 and 4, the head portion 180a is not fitted into the locking groove 122 of the barrel 120.

Now, the operation of fastening the barrel 120 to the socket 110 will be described.

As shown in FIG. 4, when the handle 180b of the snap ring 180 is pressed while the snap ring 180 is fitted to the incision slit 121, the diameter of the head 180a becomes large, and the size of the locking groove ( It extends to 122 and is temporarily placed in the locking groove 122 so that the barrel 120 can be easily extrapolated to the socket 110 (relatively, the socket 110 is easily inserted into the barrel 120). Let's do that.).

Now while inserting the socket 110 into the barrel 120, the moment the groove rim 110a of the socket 110 comes to the position of the snap ring 180, when the grip portion 180b that is held and pressed is released, the elastic restoring force is released. By the diameter of the head 180a is returned to its original state, the head 180a of the snap ring 180 is fitted while being closely adhered along the groove of the groove 110a of the socket 110 to be fastened to the socket 110.

In this case, as shown in FIG. 5, the head 180a of the snap ring 180 fitted into the groove frame 110a of the socket 110 is also fitted into the locking groove 122, and thus, the head 180a of the snap ring 180. While the socket 110 is fastened at the same time to prevent the socket 110 is fastened to escape from the barrel (120).

If necessary, by simultaneously configuring the thickness of the head portion 180a that is simultaneously fitted to the locking groove 122 and the groove frame 110a, simultaneous locking may be made easier.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is self-evident to those who have.

Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
