LED Street Lights in Dubai-Will They Succumb the Heat?

LEDs love the cold. While other light sources at minus temperatures weaken, LED running in cold, winter outdoor lights and co. to the top form. The downside: You can not. Already a temperature increase of 10 ° C shorten their life span by half. That’s a rule of thumb.Light-emitting diodes appear to have overcome this weakness. Because in a heat test, LED street lights survived even a summer in Dubai.

LED lamps can be pretty hot. A powerful LED chip manages up to 120 ° c. So that the heat does not “head” increases the semiconductor crystal, it takes an aluminum heat sink, which derives the heat out of the housing to the environment. A not well functioning cooling is even the main cause for failure for LED bulbs. As for a proper, the temperature balance of the lamp must be as low as possible and homogeneous. Researchers have long been working on a solution and continue to do it. That technology is already very far is demonstrated the fact that modern LED lamps defy already extreme weather conditions and are still without a service life of 50,000 hours.

Successfully Passed: LED Defy Desert Climate

That LED are suitable not only for cooler climes, proved a test carried out in the summer of 2013 with LED street lights. These were operated the entire summer months through maximum performance and maximum amperage (700mA). But not in the rainy Hamburg or at night, but middle of the day on the Palm Island in Dubai attemperatures above + 50 ° c and direct sunlight.

Despite The Tough Conditions, LED Street Lamps Working Please

The permissible temperature range has been exceeded in the test at any time, so that the over temperature protection to not only had to take action. The secret: a sophisticated thermal management.
Thus the proof is provided that LED lamps also under extreme heat work now and that up to 50,000 hours. Due to the moderate climate, the life expectancy of LED street lamps in Central Europe is even higher.
