Temperature Testing Module
- The technology involved with creating an LED relies on something called a p-n junction. This type of interface is between two materials heavily modified so that one is really negatively charged and one is very positive. The emission of light occurs when particles change from high energy states to low at distinct energy levels. The energy in the system due to heat can change the number of energy states available, affecting the light output.
- The performance of every LED is evaluated in both extremes of temperature to determine estimated lifespan, such as in LM-80 or LM-82 testing. Additional values, such as peak intensity and wavelength, are desired by the manufacturers of LEDs looking to use them in specific applications. The TEC testing module designed by Gamma Scientific allows the regulation of temperatures at the LED itself from +105°C to -25°C with nitrogen purging in both steady DC or pulsed configurations using a 2-channel source.
- Lastly, each LED being tested has a specific contact configuration when surface mounting to a PCB, therefore we offer a customization service to tailor the testing media for your specific LED. Extra care has been taken to isolate physical surfaces so that only the LED itself is being regulated for heating efficiency.
