The heat dissipation problem of led street lights

The heat dissipation problem of led street lamps has been plagued by developers in the led lamp industry. Nowadays, lamps and lanterns basically use aluminum alloy with inserts as radiators. The heat dissipation effect of this kind of heat sink is not ideal, and the heat sink usually reaches a higher temperature. The radiator industry, as a supplier of the street lamp industry, has specially developed LED street lamp radiators, combining the following aspects: 1. Break through the existing finned aluminum radiator with unsatisfactory heat dissipation problem. Existing ceiling holes Most of the lamps use finned aluminum as the heat sink. The heat dissipation effect of this type of heat sink is not ideal, and the heat sink usually reaches a higher temperature. 2. Use insulating and heat-dissipating plastic instead of aluminum alloy to make heat sink. South Korea has developed a kind of LED insulating and heat-dissipating plastic in 2009, which increases the heat radiation capacity by 4-8 times while keeping the heat dissipation capacity equal to that of aluminum alloy. The LED heat sink made of this heat dissipation material can greatly improve the overall heat dissipation effect. 3. Using the principle of liquid convection, a ceiling hole lamp with good heat dissipation performance is provided. The heat absorbed from the lampshade by the coolant in the liquid tank installed on the lampshade is used, and the coolant is used in two liquid storages with different heights. The natural convection between the tanks dissipates the heat absorbed by the cooling liquid from the lampshade, so that the lampshade of the ceiling hole lamp is well cooled. 4. It can be flexibly rotated and is easy to install. Because the cooling liquid convection pipe connected between the two liquid storage tanks has a bellows structure, and the bellows structure can be stretched and bent, it will not hinder the flexible rotation of the lampshade, and is also convenient installation.
