Description

{LED LIGHTING DEVICE}

The present invention relates to an LED lighting device, and more particularly, to an LED lighting device capable of radiating heat generated from an LED lighting lamp or using the LED lighting device for heating.

Recently, lighting devices using LED devices are replacing fluorescent lamps for energy saving of lighting devices.

An advantage of an LED device is that it is a high-efficiency, environment-friendly device, and a low-cost device can be realized. Conventionally, incandescent lamps or fluorescent lamps use a filament system or a rechargeable gas as a medium, so the higher the temperature, the higher the efficiency. However, in the case of an LED device, if heat dissipation is poor, the efficiency is lowered, and a malfunction of a driving driver and a device breakage may occur.

Various methods for heat dissipation of an LED device have been studied up to now, and a heat sink using a heat sink or a die-casted metal material is mainly used. There is also a method in which an aluminum material is extruded and used.

Korean Patent Application No. 10-2010-0010530 "A lighting device using a light emitting diode" shows an example of a heat dissipation structure in an illumination device using a plurality of LED elements.

However, in the case of the conventional LED lighting apparatus, the function of LED heat dissipation is primarily disclosed by using the structure of the heat sink or the like, but attempts to use heat generated from the LED lighting apparatus as other energy have not been disclosed. In addition, if the heat generated by the LED lighting device installed in the indoor space increases the room temperature in summer, if the heat generated by the LED lighting device can not be discharged to the outside, extra energy use for indoor cooling may be increased.

The heat discharge pipe may be a double pipe whose one end is fixed to the outside or the ceiling and the other end is adjusted in length along the one end.

The heat discharge pipe may have a plurality of corrugations so that the length thereof may be variable.

The LED illumination device may further include a cover for closing a lower end of the heat discharge pipe when the heat discharge pipe is separated from the heat collection pipe.

The LED lighting apparatus according to an embodiment of the present invention may be configured such that the LED lighting apparatus is cooled as needed by coupling or separating a heat collecting unit for collecting heat and a heat discharge pipe having a variable length, So that the efficiency of energy use can be increased.
