Mounting assembly for electrodeless lamp

The present invention relates to a fastening assembly for an electrodeless lamp, and more particularly, to fix the electrodeless lamp inside the luminaire where the electrodeless lamp is installed, to prevent vibration from being transmitted from the outside to the electrodeless lamp, and to provide the vibration assembly. The present invention relates to a fastening assembly for an electrodeless lamp which can prevent the electrodeless lamp from being separated from the fixed position.

In general, the electrodeless lamp is used as a light for a bridge or a building for aesthetics of a city, and provides a beautiful night view through lighting.

As described above, a lamp using an electrodeless lamp installed in a bridge or a building has a transformer core that wraps the electrodeless lamp inside the housing, as disclosed in Patent Application No. 10-2004-47690, 'Installation Assembly for High Power Electrodeless Lamp'. The radio frequency energy radiated from the RF source is inductively coupled to the electrodeless lamp so that the light is emitted and the mounting bracket surrounding the outer circumference of the transformer core is fastened and fixed to the inner wall of the housing by a fastening member such as a bolt.

Here, in the lighting lamp using the electrodeless lamp as described above, the fastening member is fixed to the through hole formed in the housing by the fastening tool such as a driver or the like. The process is done.

Therefore, the illumination lamp using the electrodeless lamp as described above, when installed in a bridge or building is shaken by the vibration of the vehicle or wind passing through it, and thus the fastening member for fixing the electrodeless lamp inside the housing by the vibration It will slowly loosen by shaking little by little. Accordingly, the electrodeless lamp has a state separated from the internal space of the housing, so that the high frequency generating means for providing radio frequency energy to the transformer core and the winding connected to the transformer core are disconnected so that the light is emitted from the electrodeless lamp. You won't be.

Therefore, when the illumination cannot be emitted from the electrodeless lamp as described above, that is, during maintenance, the fixing member is released using the fastening tool, the electrodeless lamp is replaced, and the fastening member is fixedly inserted through the fastening tool. The problem is that the work is very cumbersome because the process must be performed.

Accordingly, a fastening assembly for preventing maintenance of an illumination lamp using the electrodeless lamp and preventing the installation bracket for fixing the electrodeless lamp to the inside of the housing from being easily detached from the fixed position by vibration or the like has emerged.

Accordingly, an object of the present invention is to provide a fastening assembly for an electrodeless lamp that can be fixed to the electrodeless lamp inside the luminaire where the electrodeless lamp is installed to prevent vibration from being transmitted to the electrodeless lamp from the outside.

Another object of the present invention is to fix the electrodeless lamp inside the luminaire where the electrodeless lamp is installed, but the electrodeless lamp is separated from the fixed position by the vibration even if vibration is transmitted from the outside to the electrodeless lamp. It is to provide a fastening assembly for an electrodeless lamp that can be prevented.

In addition, another object of the present invention is to provide a fastening assembly for an electrodeless lamp that can be easily carried out without the need of a fastening tool during maintenance of the electrodeless lamp.

Meanwhile, the object of the present invention is not limited to the above-mentioned objects, and other objects not mentioned can be clearly understood by those skilled in the art from the following description.
