LEDs need to be cooled to prolong their lifetime and improve performance. Theoretically, both natural and forced convection can be used to cool LEDs. However, in practice, forced convection is rarely used due to the relatively low reliability of the traditional rotary fan. Even though a heat sink with natural convection is a reliable solution, it is usually very heavy, bulky and relatively high in cost. For example, a 15-20 lb heat sink is needed to cool a 200W LED.
Now imagine an effective thermal solution for the 200W LED that weights less than 2 lbs – this is the innovation that Bimitech’s solutions enable.
