Abstract: A method of making a light emitting diode (LED) lamp is disclosed. Included are steps of: providing a metal heat sink having a cylindrical portion formed with flat planar surfaces extending longitudinally around the outer surface; providing flat LED boards that are attached to the flat planar surfaces; providing a circular LED board mounted to the top end of the cylindrical portion; providing a turret connector board with electrical connection ports to electrically join the LED boards; providing a driver circuit board and electrically connecting it to the turret connector board; connecting the flat LED boards to the driver circuit board; securing the circular LED board to the top open-end; and securing the flat LED boards to the flat planar surfaces. Optional steps include: providing a mounting plate of heat conducting metal; applying thermal compound; providing and installing a transparent cover; providing and attaching a mount to the incandescent lamp.

Abstract: An angle iron forms two sides of a right isosceles triangular housing. These sides are each apertured and the apertures are provided with metal-framed lens plates which bolt onto the housing sides. Preferably, in one instance the lens material is mounted in the plate for ease of access to the interior of the housing and in the other instance the lens is mounted in the aperture and retained by the frame plate. A fluorescent lamp tube assembly is received inside the housing for providing illumination through both lenses. Access thereto is via removal of a metal-framed lens plate. The housing has mounting elements which permit a user to flush mount the housed light source, e.g. on a mining machine.
