Abstract (en)

This invention discloses a kind of high power LED lamp that consists of lampshade, high power LED light source and its driving circuit, heat sink, lamp holder and the bearing base. The LED light source is fixed on the heat sink, its two poles are electrically connected with the corresponding control terminals of the driving circuit board; the upper part of the bearing base supports the heat sink unit, the lower part connects with the lamp holder; the above mentioned LED light source consists of a high power LED which is integrated by a set of multi-chip modules. The LED light source is either hooded with the heat sink under the lampshade together or the LED light source hooded under the lampshade independently. The invention high power Led lamp is environment protective and energy-saving with long performance life. Adopting new type of structural design can increase the radiation brightness efficiently. The heat-sinking and anti-vibration capability is also greatly improved with even radiation and higher brightness.
