LED’s create internal heat that reduces the lifespan of the LED but more importantly decreases the LED output as temperature increases. Bottom line is that poor heat management of the LED light causes light output to decrease the longer the light is powered on.
Vision X Prime Drive and Electronic Thermal Management (ETM) are specifically designed and engineered to maximize LED lifespan and provide a constant high output no matter how long the LED is used. Using advanced PWM (pulse width modulation) technology the light output is maintained when ambient temperatures or input voltages change.
Using Pulse Width Modulation (PWM), the LEDs are being turned on and off at a frequency quicker than the human eye can detect. This technology allows the LEDs to be driven hard whilst still achieving a long life span of 50,000 hours.
In an extraordinary situation where the light is subjected to massive heat overload, a self protection protocol is engaged to reduce the light output, until such time as the heat overload retreats to normal parameters.
Designing a Heat Sink is a fine science. Some heatsinks do not have the correct amount of surface area, some do not take into consideration the gaps between fins to enable air flow. Some have horizontal fins, when they are positioned vertically. The main design fault with the latter is that heat rises, rather than dispersing the heat away from the P-N Junction. High Density heatsinks provide a dense thermal mass to provide better cooling compared to porous castings and extrusions.
