What You Need to Know About LED Lights and Heat Production

Heat negatively impacts the performance of industrial lighting systems. Traditional lighting technologies, such as incandescent and metal halide lamps, are notorious for producing large amounts of heat during operation. As a result, less energy is converted to light, contributing to more heat (and a rise in temperature) in the surrounding environment. LED lights address this issue through their solid-state designs.

 

Managing Stable Operating Temperatures

 

It is important to point out that LEDs do indeed produce heat (contrary to popular belief). Though without the use of filaments, LEDs do not generate large amounts of it.

 

By comparison, incandescent units emit up to three times more heat than LEDs. One of the main reasons LEDs operate cool is due to low energy consumption. Moreover, the light source does not produce infrared radiation during illumination (not applicable to infrared LEDs). Infrared bands are responsible for the presence of heat surrounding conventional lighting systems.

 

LEDs may also come equipped with a cutting-edge heat sink to improve heat management.

 

Thermal Heat Sinks

 

A robust heat sink can help manage thermal fluctuations in LEDs when in use. The component works by directing heat towards a path for active cooling. Heat can be directed outside of the fixture, wherein the surrounding environment helps cool down the unit. The three methods applied to this process includes: convection, conduction and radiation.

 

The material used also affects the efficiency rate at which heat is managed within the LED lamp. For low-cost heat dissipation, copper is a common material applied by lighting manufacturers. Aluminum can also be utilized for such purposes.

 

Compact LEDs typically incorporate thermoplastics or ceramics. This allows the luminaries to be installed in tight locations and high-heat environments. In particular, thermoplastics are useful for intricate lighting designs due to their small size. LED heat sinks may be coated to improve performance.
