Abstract: Solid state light engines are disclosed that emit a bright, non-symmetrical emission pattern, with a relatively high luminous flux and from a relatively small area. The light engines can be used in many different types and sizes of light sources, with some embodiments providing a light quantity, quality and distribution similar to conventional J-type Halogen light sources. The light engines are arranged with integral power supplies and heat management features that allow for the engines to provide high emission intensities while generating significantly less heat at the light source. This can result in significantly higher efficiency and greater life space. In some embodiments, the light can perform similarly to a halogen J-type Lamp 80 mm light tube, while generating similar or greater amounts of light. The light engines according to the present invention provide the capability to be used in low profile light fixtures.
