Description

technical field [0001] The invention belongs to the technical field of lighting equipment, and relates to an LED lamp, in particular to a high-power LED lamp with high heat conduction efficiency. Background technique [0002] Road lighting is an important part of urban lighting. Traditional street lights often use high-pressure sodium lamps to emit light at 360 degrees. The disadvantage of large light loss has caused a huge waste of energy. At present, the global environment is deteriorating day by day, and all countries are developing clean energy. With the rapid growth of the national economy, the contradiction between energy supply and demand in my country has become increasingly prominent, and there has been a serious shortage of power supply. Energy conservation is an urgent problem to be solved. [0003] With the continuous improvement of LED technology, LED street lights have gradually entered people's field of vision with the advantages of directional light emission...
