Abstract
A light emitting diode (LED) lamp simulation sunlight source cooling system comprises an LED lamp. A chip of the LED lamp is fixed on a metal chip printed circuit board (MCPCB) through a connecting wire. Heat conduction coating materials are plated on the surface of the MCPCB. The chip of the LED lamp and the MCPCB together form an LED single lamp set. More than one LED single lamp set can be integrally fixed on one aluminum substrate. More than one aluminum substrate is tightly attached to an aluminum heat sink and fixed. The bottom of the aluminum heat sink is connected with a metal cavity body. The interior of the metal cavity body is hollow. A cold water circulating pipeline is located on the interior of the metal cavity body. Due to adoption of a circulating water system, the LED lamp simulation sunlight source cooling system is good in heat dissipation and conduction characteristic and capable of taking away most heat and reducing temperature of the integral cooling system, and a cooling aim is achieved.
