The Importance of LED Lights in High Temperature Industry Areas
LED high bay lights are widely used in industrial environments due to their high power, high efficiency and low energy consumption. The environment of many industrial plants such as iron and steel production, pulp and paper mills is harsh and harsh. Harsh industrial environments such as high temperatures, heavy dust and vibration are serious risks to stable lighting performance. However, there are LED high bay lights that claim to work well in high temperature industrial environments. Some can withstand ambient temperatures up to 70 °C. As we all know, extreme temperature causes the lumen to depreciate and the light output to decrease.
Effects of high temperature on lighting
High temperature will damage the lighting performance. As it is known, LEDs generate less heat during operation than conventional light sources. However, higher ambient temperature will result in higher junction temperature. Drivers and other electronic components are significantly sensitive to high temperature. Prolonged high junction temperature leads to deterioration of electronic elements, accelerating lumen wear and causing possible malfunctions. As a result, the life and lighting performance of LED luminaires is shortened. High temperature can also endanger human life by increasing the risk of fire.
General temperature classifications of luminaires are 25 °C, 40 °C, 55 °C and 65 °C. LED luminaires work well at an ambient temperature of 25 °C, but LED currents drop sharply when the ambient temperature rises above 55 °C. In case of poor distribution, the junction temperature is higher than the ambient temperature. Extremely high temperature reduces lighting output. The temperature of the installed places is usually above ground level. Therefore, the rated temperature of the luminaire should be higher than the ambient temperature to ensure stable lighting performance and safety. The rated temperature should be known as the peak limit of the current that can flow through the main contacts in electrical equipment.

They are powered by built-in solar panels so they can be used in areas with no electricity grid or remote areas with no stable power supply. This saves electricity costs. It also saves energy since sunlight is inexhaustible.
