Abstract
A flame lamp comprises a light module. An example light module comprises a circuit board having a first side and a second side and defining a module axis; and a plurality of light emitting diode (LED) packages. At least one LED package is mounted to each of the first and second side of the circuit board. The example light module further comprises an optical sleeve. The circuit board is mounted within the optical sleeve. The optical sleeve comprises a plurality of optical columns each having a light emitting surface. Each light emitting surface has a profile such that one or more profiles of one or more light emitting surfaces define an ellipse in a cross-section of the light module taken perpendicular to the module axis.
