Abstract: An illumination device is provided. The illumination device includes a heat sink coupled to a housing, and the heat sink includes at least one heat dissipation pin extending from an external surface of the housing. Vent holes that expose the external surface of the housing, an inside of the housing, or an inside of the illumination device to external air are formed on a side of the at least one heat dissipation pin. An upper edge of the housing and the heat sink may be spaced apart from each other, and the spaced region may include a gap that exposes the illumination device or the inside of the housing.

Abstract: A light emitting diode (LED) lighting apparatus boosts alternating current (AC) power output from a ballast, rectifies the boosted AC power to direct current (DC) power, blocks generation of an inrush current while the boosted AC power is rectified, and controls an operation of an LED by using the DC power.

Abstract translation: 发光二极管（LED）照明装置提升从镇流器输出的交流（AC）功率，将升压的交流电功率整流为直流（DC）功率，阻止在升压的交流电源整流时产生浪涌电流，并控制 通过使用DC电力进行LED的动作。
