Description

LED fluorescent apparatus for pendant type

The present invention relates to an LED (LED) lighting device, and more particularly, the LED module and a reflector are arranged in a body to be installed in the underground parking lot, etc. to improve the lighting function, and also to force the elastic body It relates to a pendant LED lighting device that can be easily installed in a pendant type through a mounting bracket that is removable or sliding removable.

Recently, with the increase in the number of large buildings such as apartments, department stores, office buildings, residential buildings, etc., and the number of own vehicles is increasing, the basement of the building is mainly used as a parking lot. As the number of cars parked in the basement of the building increases, the parking lot also becomes large, which requires a lot of money to manage the parking lot. Cost and maintenance costs such as accident prevention and lighting for the convenience of parking lot users. In large underground parking lots, most of them are illuminated with considerable illumination and CCTVs are installed in case of an accident such as a crime.

As described above, as a luminaire for illuminating an underground parking lot, a fluorescent lamp having a relatively low power consumption is used, but a large number of fluorescent lamps are used to obtain a considerable illuminance, resulting in high power consumption.

Accordingly, fluorescent light type LED lighting fixtures have been disclosed to replace fluorescent lights in underground parking lots so that they can be illuminated for a long time with considerable illumination. Such conventional fluorescent light type LED lighting fixtures have an advantage of easy installation, but have a light weight structure. Because it is manufactured as a defect, it is easy to break or break down and cannot effectively radiate heat generated from the LED.
