2. LED Light Performance at Different Temperatures

2.1 How Does the LED Light Perform At High Temperatures?

LED lighting has come a long way from its humble beginnings when it used to overheat easily. To address the issue, manufacturers installed fans to keep the LED light working even in high temperatures. The latest LEDs can withstand heat-related lumen depreciation. They can easily channel excess heat to ensure that it does not affect the drivers. There are some LED lights that even come with a compensation circuit that performs well in different temperatures. However, higher temperatures require high-temperature LED lights as these are designed to last.

2.2 How Does the LED Light Perform At Low Temperatures?

Since LED lights rely on a driver to work, they perform rather well at lower temperatures. In fact, LED lights tend to thrive when the temperature falls. A cold environment does not affect LEDs as they are semiconductor light sources that require current to emit light. Besides, the thermal stress imposed on the driver and diode would be a lot less when the temperature is less. Hence, the lighting would offer a better lumen output.

3. An Optimization Guide for LED Light Heat Dissipation

To get the most out of LED lighting, it is crucial to master heat dissipation. Otherwise, you would need to get the lighting replaced more often. In order to optimize LED light heat dissipation, you have to understand its key components which include a lens, a substrate, a phosphor, and a die.

3.1 What Are The Effects Of Poor LED Heat Dissipation?

When there is poor LED heat dissipation, the LED lighting would heat up which would take a toll on their efficiency. This is why it is vital that you focus on maintaining a lower temperature. Otherwise, the lighting will need to be replaced more frequently. Even though light output tends to fall with time, the process would be accelerated when there are higher temperatures. If LED lighting is exposed to prolonged heat, its life would be decreased. Hence, there is a need for thermal CFD simulation.

3.2 Thermal Design Considerations

In order to ensure that the LED lighting thrives, there are certain thermal design considerations that have to be kept in mind as mentioned below.
•LED Spacing & Arrangement: Since the spacing between LEDs affects thermal power density and increases their temperature, spacing is recommended. LEDLUCKY offers high temp LED high bay lights that have sufficient spacing.
•LED Module Choice: There are different types of LED lighting available including a direct in-line package to multiple chips onboard LEDs.
•Printed Circuit Board Core Material: It hosts the LEDs by redirecting heat away from the components. FR-4 is the most commonly used material. To improve thermal resistance, thermal vias can also be added.
•Contact Surfaces and Thermal Interface: To improve the thermal design process, the transfer of heat from one component to the next has to be considered. As imperfect surfaces may be used, there is a need to reduce the points of physical contact. It would help fill the gap with air to ensure that the LED lighting continues to operate.
•Heat Sink Design: It plays a huge role in how LED heat dissipation is managed. Heat sink design should focus on conducting the heat away from the surrounding environment. It would circulate the ambient air to cool it.
•Active Cooling: Liquid cooling or small fans are necessary for active cooling. As there are a number of constraints that have to be considered, it is crucial to adopt a passive cooling approach for enhancing air circulation and effective heat management.

4. How to Choose a High-Temperature Lamp?

The following tips will help you pick out the best high-temperature lamp.

4.1 Resists Corrosion

One of the most important things that you have to consider when on the lookout for lighting for industrial buildings is fixture corrosion.

4.3 Reduces Fire and Contamination Risks

The next thing that you have to consider is the air which is likely to contain combustible dust, ignitable particles, vapors, or flammable gasses. Things can get tricky as the fixtures would be operating at a high temperature. If there is a lot of heat, the particles or gasses would spark which would have deadly consequences.
Besides, if your facility creates dust, debris, or works with water, there is a high possibility that the fixtures might get contaminated. Hence, you would have to install sealed fixtures for keeping the contaminants away from the fixture. It is the only way that you can extend the life of the lights and protect against a power surge. You could use hazardous location high bay LED lights to handle such a situation. As the electronic components would be completely sealed, you would not need to worry about any sparks caused by the ambient air. It would also ensure that you benefit from low operating temperatures, a T4 rating, a division 2 rating, and industry-leading efficiency.

4.4 Shatter-Resistant

When you are searching for lighting for a retrofit, you have to consider the materials that it is made of. Fixtures that are made of a breakable material such as glass are likely to shatter and injure your employees. A delay in cleanup would only make matters worse. Moreover, you would incur additional expenses to replace the damaged fixtures. Hence, you have no option but to opt for lamps that are rated for impact. It would help minimize downtime.
