LED lighting device of back putting on and taking off structure {LED LIGHTING APPARATUS HAVING DETACHABLE STRUCTURE AT REAR SIDE}

TECHNICAL FIELD The present invention relates to an LED lighting device, and more particularly, to an LED lighting device having a back detachable structure that can easily attach and detach an LED lamp from the back.

It is known that 70% of the information that people experience everyday is acquired by sight. The color of the object perceived through vision plays a big role in human emotion. Humans may recall memories of the past through certain colors or induce some emotions. Therefore, the lighting that can determine the color of the object in everyday life is very important for the emotion of the person. In addition, since the lighting environment can change the brain waves of the worker, the lighting is known to directly affect the fatigue of the worker.

Generally, a lighting device refers to a device for fixing or protecting a light source by reflecting, refracting, or transmitting light of the light source. As a conventional lighting fixture, an incandescent lamp and a fluorescent lamp are typically mentioned. Incandescent lamps use light emitted by vacuuming the inside of a bulb and applying heat to the filament to generate heat. Fluorescent lamps gain energy when energy emitted from the filament of one electrode collides with mercury vapor, which is filled in the glass tube. It is to use the phenomenon of light. Conventional light bulbs such as incandescent lamps or fluorescent lamps not only have high power consumption, have low illuminance problems, and also have a limit of durability due to short lifespan of filaments.

Recently, light bulbs or lamps implemented with LEDs having various effects as compared to incandescent and fluorescent lamps have been developed and sold. An LED (Light Emitting Diode) refers to a light emitting diode that emits light and emits light of various colors such as white, red, green, blue, and yellow. In general, a light emitting diode, or LED, has a pn junction structure and when forward current is applied to the diode, electrons in the n region of the chip are accelerated by the electric field to move to the p region, and in the p region, the acceptor level or valence band Recombination with the holes emits light with energy corresponding to the potential difference depending on the chip material. This phenomenon is called injection type electroluminescence. Such a device is called a light emitting diode (LED). Such representative LED chip materials include GaAs, GaAsP, GaP, GaAlAs, SiC, and the like, and exhibit various light emission characteristics from the crystal structure according to these materials.

Lamps implemented with LEDs require only about 10% power consumption compared to conventional lamps implemented with incandescent lamps, and require only about 50% power consumption compared to conventional lamps implemented with fluorescent lamps. LED lamps not only minimize eye fatigue even after prolonged use, but also have an advantage of about 10 times longer than incandescent lamps and about 8 times longer than fluorescent lamps. In addition, the lamp implemented by the LED has excellent durability because it can be used semi-permanently due to the characteristics of the LED.
