<p>The present invention relates to a power supplying device having increased efficiency of heat dissipation. More particularly, the power supplying device: rectifies incoming alternating current power; converts the alternating current power into direct current power appropriate to turn on an LED lamp; and provides the direct current power to an LED lamp. The power supplying device having increased efficiency of heat dissipation effectively dissipates heat generated therein. Therefore, the power supplying device extends the lifespan of the LED lamp and dramatically enhances quality characteristics of the LED lamp. A cover of the power supplying device comprises 90 weight% of flame retardant polycarbonate and 10 weight% of alumina powder. The cover is formed on the case. A mixture of 25-35 weight% of liquid silicone, 25-35 weight% of a silicon curing agent, and 35-50 weight% of alumina powder is applied on the surfaces of the parts inside the case.</p> |
