Such a spotlight must be replaced periodically or by breakdown due to the limited lifetime of the light bulb, You should also periodically clean the floodlight.

In such a high-altitude lighting, the bulb is arranged at a high place, so that the work is carried out using a crane or a ladder for high-altitude work for cleaning and exchanging bulbs.

However, a method of using a crane or a ladder is more inconvenient than a work on the ground, and the operator is exposed to a high risk such as an electric shock and a fall, and there are also many problems such as an increase in the maintenance ratio due to use of the auxiliary equipment .

Accordingly, in recent years, a large number of illumination lamps having a lifting device have been disclosed in order to solve the above problems. Such a lifting lighting device includes a fixed body 30 which is basically fixed on a ceiling portion, A wire 40 connecting the elevation unit 10 and the fixed body 30 to each other and connecting the wire 40 to the elevation unit 10, And a motor 21 driven so as to be able to move up and down.

However, in the lifting lighting apparatus thus configured, since the connecting means 102 for connecting to the socket of the fixing body 30 is located outside the wire 40, in the process of lifting the elevating unit 10 after replacing the lamp There is a problem that the connecting means 102 located outside the wire 40 swings in the up-and-down direction or rotates in the left-to-right direction, so that the connection for electrical contact can not be smoothly performed. Particularly, in the case of an outdoor stage, there is a structural problem that it is very difficult to connect the connecting means 102 to the socket of the fixed body 30 due to the influence of wind.
