LED street light heat dissipation

by:SUNFREE     2021-02-03
LED street light heat dissipation has been plagued by the developer of the LED lighting industry. Manufacturer of LED lights ED street lamp light is higher than high pressure sodium lamp many color, high pressure sodium lamp only around 23, color rendering index and the LED street light color rendering index above 75, think in terms of visual psychology, to achieve the same brightness, LED street light can, on average, more than 20% lower than the high-pressure sodium lamp. LED street lamp manufacturers of LED street lamp with conventional street lamps, the LED light source adopts low voltage dc power supply, by GaN power type synthetic efficiency white light, blue light leds and yellow is efficient, safe, energy-saving, environmental protection, long service life, fast response speed, high color rendering index of unique advantages, can be widely used in road. Housing available, resistance to high temperature of 135 degrees, low temperature resistant da 45 degrees. Today's lamp basically made out of aluminum alloy, plug-in as a radiator. The radiator cooling effect is not ideal, radiator usually at high temperature. Has developed the LED street lamp radiator radiator industry as a supplier of street lighting industry, combining with the following aspects: 1. Break through the existing aluminum radiator cooling effect is not ideal problems existing droplight mostly adopts the fin for aluminum radiator, radiator cooling effect is not ideal, heat dissipation can achieve higher normal body temperature. 2. Using heat insulation plastic instead of aluminum alloy manufacture heat sink. In 2009, South Korea has developed a LED heat insulation plastic, while maintaining the heat dissipation and aluminum alloy, thermal capacity will be increased 48 times. Made of the heat dissipation material LED radiator can significantly improve the overall heat dissipation effect. 3. Using the liquid convection principle, provides a good heat dissipation performance of dome light. Using installed on the chimney of the liquid in the tank coolant to absorb heat, as well as the cooling fluid in two different height of the liquid storage tank, the natural convection between the will be absorbed by the coolant heat released from the chimney, thus make the chimney of droplight to obtain the very good cooling. 4. Rotating flexible, convenient to install due to the connection between the two tanks cooling fluid convection tube with corrugated pipe structure, corrugated pipe structure can be flexible bending deformation, don't hinder the flexible rotation of the lampshade, and ease of installation. This invention USES the newly developed LED street lamp radiator to solve the heat dissipation problem of LED street light.
