LED lighting device having a prolonged life during high temperature operation

A LED lighting device, comprising:

• a LED light housing comprising a hollow outer shell, a reflector cup mounted in said hollow outer shell and a lens mounted in said reflector cup, said hollow outer shell comprising an accommodation chamber, an opening located in a bottom side thereof in communication with said accommodation chamber and the space outside said LED light housing and a planar mounting surface located on the center of a top side of said accommodation chamber and facing toward said opening, said reflector cup being mounted in said accommodation chamber of said hollow outer shell, said reflector cup comprising a lens mounting hole located on the center of a closed top side thereof and a conical reflective surface defined therein and gradually increased in diameter from said lens mounting hole toward an opposing bottom open side of said reflector cup, said lens being mounted in said lens mounting hole of said reflector cup, said lens comprising a light exit surface facing toward said conical reflective surface of said reflector cup;
• and
• a LED light-emitting module comprising a circuit board mounted between said planar mounting surface of said hollow outer shell and said lens and defining a front side and an opposing back side, a plurality of light-emitting diodes arranged on a center area of the said front side of said circuit board to face toward said light exit surface of said lens, a control circuit installed in said circuit board, said control circuit comprising a driver IC mounted in a border area at the said front side of said control circuit and a capacitor mounted on the said back side of said circuit board, and a power cord electrically coupled with said circuit board and said driver IC and extended out of the said back side of said circuit board for connection to an external power source.
