Abstract: A light dispersion device for providing a predictable lighting pattern comprising a Light Emitting Diode (LED) source and a lens. The lens comprising a first optical element for collecting light emitted by the LED source and refracting light into an intermediate lighting pattern, and a second optical element for collecting at least light refracted in the intermediate lighting pattern and refracting light into the predictable lighting pattern. A lens comprising a first optical element for collecting light emitted by a source of light and refracting light into an intermediate lighting pattern, and a second optical element for collecting at least light refracted in the intermediate lighting pattern and refracting light into the predictable lighting pattern.

Abstract: A lamppost head assembly including a housing compartment having a cavity, a panel and at least one fastener. The panel has a plurality of Light Emitting Diodes (LEDs) positioned on a first surface and a heat sink positioned on a second surface opposite to the first surface. The heat sink is adapted to fit into the cavity for dissipating the panel's heat into the housing compartment. The at least one fastener maintains the panel at an angle with the housing compartment from a plurality of angle options and may optionally further maintain the heat sink into the cavity.
