Abstract

The utility model provides a retractable lighting device which consists of an upper part and a lower part. A magnet at the upper part of the lighting device and a magnet at the lower part of the lighting device are mutually corresponded and absorbed; a connecting rope which is extended out of the roper winder of the connecting rope fixed at the upper part of the lighting device pulls the lower part of the lighting device; the magnet and the rope winder lead the upper part and the lower part to be tightly connected with each other; and the two moving contacts at the lower part of the lighting device are also closed with the two static contacts corresponding thereon with the absorption of the upper magnet and the lower magnet so as to lead the lighting device to form a loop and a luminophor to be luminous. When the luminophor needs to be maintained or replaced, the pull-down handle of the lighting device is downwards pulled to separate the upper magnet from the lower magnet so that the moving contacts are separated from the static contacts, the upper part and the lower part of the lighting device are separated from each other, and the connecting rope which is extended from the roper winder of the connecting rope is connected with the lower part of the lighting device to downwards run until that the luminophor can be maintained so as to replace a position which is required by the luminophor.

Description

A kind of lighting device that can stretch

Affiliated technical field

The utility model relates to a kind of lighting device that can stretch, and especially can use the place that must be installed in the higher position at lighting device, can give maintenance later on and change illuminator, brings convenience.

Background technology

At present, known lighting device all is fixed on the higher positions such as roof, high-wall, electric pole mostly, especially fixing very high at local lighting devices such as the factory building of enterprise, storehouses, when changing illuminator, need scale a ladder or use lift truck, be unfavorable for maintenance at ordinary times and change illuminator, and certain risk arranged when scaling a ladder, inefficiency, the cost of buying lift truck is high, some places can't use ladder and lift truck because the place is narrow and small at all, can make troubles to productive life.

Summary of the invention

In order to overcome higher back, existing lighting device installation site in maintenance, the inconvenience that runs into when changing illuminator, the utility model provides a kind of lighting device that can stretch, after this lighting device is installed in the higher position, no matter how to change with the rear lighting unit surrounding environment, in need repairing maintenance and when changing illuminator of lighting device, do not need to scale a ladder and use lift truck just can maintain and change illuminator.The place that this lighting device is different from other lighting devices is, it is divided into two parts up and down, top magnet and the magnet adhesive of lighting device lower part, and Winder hauls the lighting device lower part by the coiling rope simultaneously, make two movable contacts of lighting device and two stationary contact closures, make illuminator luminous.

The technical scheme that its technical problem that solves the utility model adopts is: this lighting device is made up of two parts up and down, two parts are connected by the connection cord that Winder stretches out about it, and top has one or multi-block magnet and one or more magnet of lower part corresponding mutually, attract each other lamp can not fallen down, when lighting device needs repairing maintenance and replacing illuminator, with the buckle object that can touch lighting device (as bamboo pole, rod) holds handle under the lighting device, the magnet of lighting device is drawn back, almost the movable contact of two band springs also disconnects with stationary contact simultaneously, at this moment throw off on the lower part of lighting device and top, have only scalable connection cord to be connected with top, connection cord does not disconnect with top, handle hauls the lower part decline of lighting device under the lighting device, can touch lighting device lower part and pulling or fix the lighting device lower part up to staff's hand, if unclamp handle under the lighting device this moment, Winder can be withdrawn into the origin-location to the lighting device lower part, so fix handle under the lighting device, up to maintenance, the replacing illuminator is finished, in maintenance, the staff used buckle object (bamboo pole again after the replacing illuminator was finished, rod) the lighting device lower part is caught on, send the lighting device lower part slowly, can rise along with connection cord in the lighting device lower part, up to touching lighting device top, at this moment the top magnet of lighting device and lower part magnet adhesive, almost simultaneously the movable contact of two band springs also with stationary contact closure (following two movable contacts have spring to support make tightly closed) with stationary contact, like this under the situation that need not ladder and lift truck, just can finish the maintenance of illumination apparatus and change illuminator, this lighting device is increased work efficiency, easy to use, reduce to climb dangerous purpose.

The beneficial effects of the utility model are, because this lighting device of the utility model is made up of two parts up and down, two parts are connected by a connection cord that can stretch about it, and the group magnet attracted each other lamp can not fallen down more than two parts had up and down, when lighting device needs repairing, leave behind the lighting device lower part just can illumination apparatus maintenance, change illuminator, need not the staff and use ladder, lift truck just can be finished maintenance and change illuminator, its lighting device can be increased work efficiency, easy to use, it is dangerous to reduce climbing, the advantage that reduces to inject capital into.
