Factory Direct Selling Outdoor Building Aluminum Profile
Color-coated aluminum sheet has a beautiful appearance and long-lasting corrosion resistance. Its strength is easy to install, and its fire resistance and heat preservation are very good. In addition, color-coated aluminum sheet has very good recyclability due to the particularity of its material, which can be said to be very economy.
The surface of the color-coated aluminum plate must not have obvious indentation, missing coating, or penetrating damage to the coating, and ripples, scratches, and blisters are not allowed. These are all easy to see. The most important thing is that you should carefully look at the color difference of the color-coated aluminum sheet. If you don't pay attention, it is not easy to see, but it will affect the final decorative effect during application.
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 the display and lighting fields. With the development of science and technology, advanced technology is continuously applied 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.
It is generally believed that the temperature of LED lights should not exceed 80 degrees. 60-70 is an ideal environment for use, but it is difficult to do in a real environment. Let's take a look at the usage of street lights that use LED light sources in practical applications:
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.
