Description

Lighting apparatus

The present invention relates to a lighting apparatus, and more particularly, to an LED lighting apparatus for coupling a diffuser plate to a case using a magnetic material or the like.

In general, widely used lighting devices can be roughly divided into incandescent and fluorescent lamps, one of which is usually a spiral twist of a tungsten alloy to form a filament. So, when the filament is electricity, it generates a lot of heat, the temperature rises and the light is emitted.

In addition, the fluorescent lamp is further developed from the incandescent lamp by the filament heat generation as described above, and uses electric discharge at high voltage. Fluorescent lamps contain a small amount of mercury vapor and argon gas for easy discharge, and then attach electrodes to both ends. When a high voltage is applied between the electrodes, discharge occurs and radiates light.

However, in the case of the incandescent lamp as described above, there is a disadvantage that a lot of electricity is consumed when turned on for a long time. Therefore, it is not economical to use indoors such as buildings that need to be turned on for a long time, but it may be advantageous to use an incandescent lamp in a place such as a toilet where ON / OFF should be frequently repeated frequently.

On the other hand, since the fluorescent lamp is not discharged properly when the end of life can be felt badly flickering. If it flickers badly when it is lit, the glow lamp has lost its function. If the edge of the fluorescent lamp turns black and the light flutters or flickers, the lamp has reached its end of life. Therefore, there is a serious disadvantage of eye fatigue.

In recent years, a light emitting diode (LED), which is used for lighting, emits light when an electric current is applied to a PN junction of a diode. Silver has the advantages of fast turn on / off speed, low power consumption, long life, light emission of various colors, and low glare compared to other light sources for lighting.

Therefore, in recent years, the use of office and home lighting devices using LEDs is gradually expanding.

However, in the conventional lighting device using the LED, since the combination of the case with the LED inside and the diffusion plate mounted on the bottom is made in such a way that it is not easy to disassemble, such as a plurality of screw coupling, cleaning of the lighting device After removing the entire city lighting fixture from the ceiling and lowering it to the floor, the diffuser plate was removed from the case and cleaned, and then the screw was attached to the case and installed on the ceiling.
