Description

technical field [0001] The invention relates to an LED lamp and a manufacturing method thereof, in particular to an LED lamp with light weight and fast heat dissipation and a manufacturing method thereof. Background technique [0002] Light-emitting diodes (LEDs) have the advantages of low energy consumption, power saving, long life, and durability, so they are expected to replace traditional lighting as the future lighting source. Among them, LED street lamps are highly respected by urban construction and various enterprises and institutions because of their energy saving and high intelligence. However, as the power increases, the waste heat of the electric heat flow generated by the LED cannot be effectively dissipated, resulting in a serious drop in luminous efficiency. The definition of LED service life is that when the LED luminous efficiency is lower than 70% of the original luminous efficiency, it can be regarded as the end of the LED life. The luminous efficiency o...
