Description

{LED BASED LIGHTING DEVICE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an LED lighting apparatus, and more particularly, to an LED lighting apparatus that is easily installed in a dark working space and capable of dimming control.

Generally, a lighting apparatus is indispensably required in a work space in which light is not projected. In particular, when workers perform work in construction sites such as night work sites, tunnel work sites, etc., the lighting apparatus must be always installed in the work space. If the operation is a long-term operation, the lighting-related costs such as the purchase, installation, maintenance and management of the lighting apparatus, electricity charges, etc. may be significant. For example, long-term tunnel construction is almost sealed inside the tunnel, so the lighting-related costs are considerable, and the lighting equipment may be damaged easily due to the microfabrication, discharge water, etc. due to blasting and structure arrangement work. In addition, a large number of lighting apparatuses in the tunnel inside the tunnel must be arranged at regular intervals on the inner wall of the tunnel, and it is required to provide a considerable brightness and optical range, and it is required to have robustness and durability Furthermore, energy-efficient products must be used to reduce electricity costs.

However, the conventional lighting apparatuses do not satisfy these conditions. A metal lamp, which has been used in a conventional tunnel construction site, is provided with a fixed structure on an outer column fixedly disposed on a wall surface of a tunnel construction site, and then the metal lamp is fixedly disposed thereon, The metal lamp has a high electric power consumption because it is based on high-power consumption, and it is easily damaged by the physical impact which may occur in the tunnel construction site, It was not possible to meet the required light level required for the tunnel construction site unless it was quite narrow and a significant number of lamps were placed. Therefore, there is a demand for an illumination device having a wide light emitting area and being easily installed and removed.

On the other hand, the lighting apparatus installed in the conventional work space is manually turned on and off, and it is generally used to emit light of the same brightness irrespective of whether or not there is a person in the work space. This causes the same brightness to be emitted even when unnecessary, thereby increasing the energy used for the lighting apparatus and the related costs. In particular, since the work space in which almost no light is projected during the daytime, such as a tunnel construction site, should be kept lit continuously for a long period of time during the operation period, maintaining the brightness of the illuminator equally increases the use energy and related costs There is a problem that the life of the lighting apparatus is shortened. Thus, by keeping the brightness of the lighting device bright only when a person is present in the workspace and by dimming the brightness of the lighting device or by completely extinguishing the lighting device completely if the person is not present for a predetermined period of time, There is a need to reduce energy and related costs.
