Patent ID: 11415309

Abstract:
An LED lighting device comprise a first portion, wherein a lamp cap is disposed thereof, wherein the lamp cap extends in a first direction; a second portion, wherein a case and a power supply are disposed thereof, wherein the power supply is disposed in the case; a third portion. A heat exchange unit and a light emission unit are disposed thereof, the light emission unit and the heat exchange unit are connected and form a thermal conduction path, the light emission unit and the power supply are electrically connected, When the first direction is parallel to the horizontal plane, the light emitting unit of the LED lighting device provides downward light emission when working. The first portion, the second portion and the third portion are arranged sequentially. The LED lighting device is installed horizontally, wherein after the lamp cap is disposed, the moment is F=d1*g*W1+(d2+d3)*g*W2, wherein the moment satisfies the following formula: 1 NM<d1*g*W1+(d2+d3)*g*W2<2 NM.
