LED lifetime can typically be increased using strobe mode where possible. Strobing the light or turning the illu-
mination on and off (using PNP or NPN lines) allows less temperature build up at the LED junction. The junction
temperature of the LED is directly correlated with the lifetime of the LED chip. Maximum ambient air temperature
= maximum 40°C/104°F.
LEDs naturally lose some intensity over time because of heat. Using the dimming and setting a reference
brightness is a method for keeping the brightness level constant over a very long time, especially on
brightness critical applications. wenglorTPL products have been integrated in factories since 2006, many of which
are still in operation today. LED lifetime and heat management are at the forefront of our design considerations.
