An LED(Light Emitting Diode) device is provided to prevent an operation temperature of a light emitting unit from rising by discharging thermal energy from the LED chip. An LED device includes a light emitting unit(1) and a heat pipe. The light emitting unit includes one LED chip or more. The heat pipe prevents the temperature rise of the light emitting unit. The heat pipe includes at least one LED chip and a printed circuit board(7). The LED chip is connected to the printed circuit board. A transparent member(3) is formed in at least one part of the heat pipe. The transparent member has a lens or plate shape. A heat sink(15) is formed in a body(13) of the heat pipe. |
