EFFECTS OF THERMAL DISSIPATION ON LIGHT QUALITY AND USEFUL LIFE OF LED DISCHARGE LUMINAIRES

Abstract:

In the present work, an exhaustive study of the impact of thermal dissipation on the luminous behavior of LED luminaires compared to incandescent ones is carried out. In LED luminaires, it is key to maintain the heat dissipation temperature of the light-emitting diodes within an operating range. The high temperatures in the electronic components are not essential to dissipate the heat generated. We carried out an experimental study of the thermal dissipation of several luminaires, both LED and discharge technology, analyzing the data obtained through a thermographic camera. The data was taken periodically, for 8h simulating real operating conditions, until the temperature has remained stable, after some time has elapsed since its connection to the electrical network. Subsequently, the data was analyzed to check whether there was a safe thermal dissipation, that is, that the maximum dissipation temperature did not exceed the limit temperature of the most restrictive material of what each of the studied luminaires is composed of. Thermal dissipation is the order of the day, materials are being investigated to be used as heat sinks that promote greater durability of LEDs associated with thermal conductivity.
