LED COOLING SYSTEM
The invention relates to a LED cooling system that effects cooling of the LED's during use, and helps the LED's have a longer operating function, and uses less electricity for the LED's to operate. The use of cooling also provides a steadier light and has greater efficiency.
1 . A high intensity LED light emission diode assembly including a metallic base which is powered to produce a cone of semi-coherent light in a lamberton distribution, which is characterized by:
a printed circuit board mounting the LED whereby the metallic base of the LED extends through said printed circuit board to achieve mounting,
a metallic heat layer mounted on the side of the printed board opposite to the LED, and in intimate contact with the metallic base of the LED, and
means to pass a fluid adjacent to the heat sink layer to absorb heat from the heat sink layer, and to effect operation of the LED at its optimum effect temperature.
2 . A diode assembly according to claim 1 where the LED is operated with an electric draw of approximately 1 amp, and puts out a light intensity of between 720 to 1200 lumens.
3 . A diode assembly according to claim 1 where the printed circuit board is between 1.0 mm to 1.5 mm in thickness and the heat sink layer is between 1.0 mm to 2.5 mm in thickness, and the fluid is water passing the heat sink layer at between 300 to 500 ml per minutes through an opening which is between 1.0 mm to 1.75 mm in diameter.
4 . A diode assembly according to claim 3 where the diode assembly emits a conical light pattern of approximately 40 degrees, and further includes a focus lens to focus the 40 degree beam as desired.
