Description

lighting device {LIGHTING DEVICE}

An embodiment of the present invention relates to a lighting device.

Light Emitting Diodes (LEDs) have advantages of being small and having a long lifespan compared to conventional light sources such as incandescent lamps and fluorescent lamps. In addition, the light emitting diode has excellent energy efficiency because electric energy is directly converted into light energy, and thus has the advantage of low power consumption. Due to these characteristics, the light emitting diode is not only used as a light source for various display devices, but is also in the spotlight as a lighting device such as indoor/outdoor lighting, signboard lighting, and general residential lighting.

When a light emitting diode is used as a lighting device, for example, a plurality of light emitting diodes may be mounted on a PCB substrate and implemented as a bar type LED module. When such a lighting device is installed indoors or outdoors, it must have a waterproof function to prevent moisture or rainwater from entering.
