Abstract
Filament type light emitting devices are disclosed. One of the light emitting devices includes a non-conductive transparent substrate, one or more light emitting diode chips arrayed above the upper surface of the non-conductive transparent substrate and each including input and output ends extending toward the non-conductive transparent substrate, and conductive transparent connection portions formed on the upper surface of the non-conductive transparent substrate and electrically connected to the input and output ends. Light transmitting regions are provided without reflectors in the vicinity of the input and output ends between the non-conductive transparent substrate and the light emitting diode chips. Thus, light is emitted backward from the light emitting diode chips through the light transmitting regions and the non-conductive transparent substrate.
