Patent abstract
An LED bulb uses an LED strip suspended between two lead frames of a stem as a light source to provide uniform illumination with wider angles. The lead frames of the stem provide an improved structural stability to the LED strip while maintaining a reliable electrical connection between the components of the stem and the LED strip. The utilization of both top-emitting and side-emitting LEDs on the LED strip further allows lights emitted in directions substantially parallel and perpendicular to the LED strip to cover a wide angle of illumination from the LED bulb.
