Recently, an AC driving method that directly drives an LED using an AC power source of 110 V or 220 V has been proposed based on such a market situation. In comparison with the conventional DC driving method, an AC driving LED lighting device And the demand for and installation of such equipment is reported to increase.

According to recent LED industry trend reports, it is expected that price and design will be an important factor in market share as well as practicality. In addition to the AC DOB (AC Driver On Board) type, AC COB ) Type LED module will be highlighted.

Accordingly, studies on LED lighting using the AC COB type and AC DOB type LED modules have been actively conducted in the lighting industry, and various LED products have been proposed and released.

However, the conventional LED lighting device having an AC driving method has been studied and developed solely for the driving circuit and method for AC driving. Therefore, there is no mechanical design suitable for practical application, LED lighting device for low power driving for 3 ~ 5W due to heat dissipation problem is being released, and LED lighting device for high power driving which has ensured heat dissipation, insulation and stability has been developed and developed. It has not been released.
