SFY Window and Door aluminum alloy profile can be used in a large number of residential, commercial and industrial appliceations. Which are included casement sliding/ Bi-fold tilt and turn/ Sunroom types. Profile are made from material that does not wrap or rust, and hence cean be used in outdoor settings as well as indoors.

The heat dissipation effect of LED aluminum radiator has a direct relationship with the service life of LED lamps.

As a new generation of solid-state light sources, LED light-emitting diodes have many advantages such as long life, high efficiency, energy saving, and environmental protection. They are widely used in display and lighting fields. With the development of science and technology, advanced technologies are continuously applied in semiconductor production to make LEDs The luminous efficiency continues to improve, and the cost continues to drop.

Although LED lights have many advantages, current LED lights only convert 20-30% of electrical energy into light energy, and the remaining 70-80% are converted into heat energy, and the heat energy generated by the LED The life span and luminous efficiency have a great influence.

According to the test, let’s take a look at the usage of LEDs at various temperatures:
Junction temperature (Celsius) 1501251007550 Service life (hours) 600010500195003900090000

As can be seen from the table, it is generally believed that the temperature of the LED lamp should not exceed 80 degrees. 60-70 is an ideal environment for use, but it is difficult to achieve in the real environment. Let’s take a look at the actual application of LED light sources. The use of street lights:

A three-month test was conducted in a domestic city, and the results found that the attenuation of the tested LED lights during use was: 8.77%, 15.5%, and 20.4%. The reason why there is such a large attenuation is because the working temperature of these street lamps exceeds 80 degrees, which means that there is a problem with heat dissipation.
