Description

Pendant type LED lighting fixtures {PENDANT TYPE LED LIGHTING APPARATUS}

The present invention is suitable for a place that requires a large number of lighting fixtures and lighting for a long time with a considerable illuminance, pendant construction is simple, can be manufactured at an economic cost and excellent heat dissipation effect pendant LED (LED) Relates to a lighting fixture.

Recently, large buildings such as apartments, department stores, office buildings, residential complexes, etc. are increasing, and as the number of cars increases, the basement of the building is used as a parking lot.

As the number of vehicles parked in the basement of the building increases, the parking lot also becomes large, which is expensive to manage. One of these costs is the cost of separate parking lot management personnel to prevent accidents that may occur in the parking lot, and the cost of facility maintenance such as accident prevention and lighting for the convenience of the parking lot user.

In large underground parking lots, crime-like accidents can occur, and most underground parking lots are illuminated with considerable illumination and CCTV is installed. 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. In addition, since the management of the lighting of the underground parking lot currently implemented depends on the collective on / off using a switch, it puts a lot of burden on the user of the building or in the case of the apartment.

In order to prevent global warming and also for the environment, conventional lighting devices such as incandescent lamps, fluorescent lamps and mercury lamps are currently being discharged, and will be completely discharged in the future. Several alternatives are being considered as alternatives to such lighting devices, the leading candidate being LED lighting devices.

LEDs are made on the principle of making electrode terminals on both P-type and N-type semiconductors and applying a voltage between the terminals to allow light to flow around the PN junction. The light emission wavelength of the LED varies depending on the material and the concentration of the semiconductor crystal, and various colors are produced. LEDs have the advantage of being an environmentally friendly lighting fixture. Unlike most lights that use mercury, LEDs do not use mercury or lead, so they are attracting attention as 'next generation light sources' in all countries of the world. In addition, unlike light bulbs and fluorescent lamps, there is no filament or electrode, so the lifespan is more than 30 times longer and the energy efficiency is more than 18 times higher, which can reduce power by more than 70%. The LED is small and light in size, consumes little power, and has a very long life that lasts for 100,000 hours, which is about 100 times that of a fluorescent lamp in one installation, and can produce various colors using the light emission wavelength of semiconductors. It is a very environmentally friendly light source, has a high luminous efficiency, and has the advantage of obtaining high output even at low currents, and because of its simple structure, mass production is possible and inexpensive. Has a strong advantage.

As semiconductor manufacturing technology and semiconductor material technology are developing day by day, LEDs that can gradually improve light efficiency and emit various colors have been developed and used.

Therefore, it is preferable to use a lighting apparatus using LED in a place where a long time illumination is required at a considerable illuminance such as an underground parking lot.

Recently, LED lighting fixtures developed to replace fluorescent lamps in underground parking lots are mainly made of fluorescent lamp types that can be inserted into existing fluorescent lighting fixtures. Prior arts related to such fluorescent lamp type LED lighting, Korean Patent Publication No. 10-2010-0003609, Korean Patent Publication No. 10-2010-0006046, Korean Patent Registration No. 10-0923982, Korean Patent Registration No. 10-0913925 , Korean Patent Registration No. 10-0906088, Korean Patent Registration No. 10-0905893, and the like.

However, such fluorescent type LED lighting has the advantage of being easy to install, but because it is manufactured in a light weight structure, it is difficult to break or break down, and it is difficult to effectively radiate heat generated from the LED. The type of LED light is hesitant to replace the fluorescent light in places such as underground parking lot where a large number of lights are required.

Therefore, in order to be able to use the lighting equipment using LED where it requires a long time illumination with considerable illumination such as underground parking lot, it is possible to effectively dissipate heat generated from the LED without the need for robust and expensive equipment. It is desirable to develop.

Meanwhile, in Korean Patent Registration No. 10-0837139, at least one light source unit in which one or more LEDs are mounted in a PCB, one light source unit installation groove having a light source unit bonding surface on one surface, and one or more grooves for installing lighting fixtures are formed on the other surface. A body made of metal and serving as a heat dissipation means, a transparent protective cover mounted on the body to protect the light source from moisture and foreign matter, and end closure members fitted to the left and right ends of the body portion, and as a holder in the luminaire installation groove LED lighting fixtures have been proposed in which a magnet is inserted or a thread is formed in the installation groove and the eye bolt is fastened as a holder.

The above-mentioned LED lighting fixture has the advantage of being able to dissipate heat generated from LED effectively while being firm but processing the bolt for eye bolt after extrusion to manufacture a body for use as a pendant type with higher heat dissipation efficiency than the attached type. Since it requires a process that has a disadvantage in productivity compared to the manufacture of the attachment-type body only by extrusion.

Generally, pendant lighting fixtures that are applied to large spaces such as underground parking lots are suspended from the ceiling in the form of pipes or bars, and these pendant lighting fixtures are suitable for mounting with openings on the top and side surfaces. Eyebolt holders with openings in the direction are inappropriate.
