Abstract
A LED bulb and light module utilizes a LED light source and directs light therefrom in a manner which improves efficiency and illumination. Ideally, the LED bulb is structured to create a virtual image whereby the efficiency of light directed out of the module is greatly improved, even with a single LED light source. The LED bulb generally includes a light pipe receiving light from the LED light source and guides the light downstream to a downstream portion which redirects the light radially outwardly.
