LED mechanical lighting fixture
First Claim
1. An LED mechanical lamp comprising an LED circuit board affixed to a metal module having a surface having a plurality of fins forming a plurality of open channels, a solid metal shroud having a central hole, the shroud placed over the metal module, to complete and cover the air channels creating an air duct, the LED circuit board generating heat and transferring the heat to the surface of the metal module causing an air intake providing a path for upward hot air flow through the center hole of the shroud, and by convection causing a flow of cool air to enter, due to the hot air uprising through the center hole causing cool air passage through the channels between the fins in the metal module surrounded by the solid metal shroud creating a convection draft to pull cool air through the intake of the air path horizontal channels bringing cool air over the metal module surface in a directed method over the LED board, cooling the metal module at its hottest point of contact with the LED circuit board.

Abstract
An LED light unit which creates an air movement over a metal surface by way of convection. This keeps the LED unit significantly cooler than with just fins alone. This is accomplished by the design of a lamp. The LED chip transfers the heat to the metal surface and the hot air near that metal rises and starts a flow through channels designed into the lamp. This brings in cooler air over the metal surface in a directed method by convection to achieve better cooling of the LED chip area.
