An LED bulb (100, 200) uses an LED strip (120, 120') suspended between two lead frames (131, 132) of a stem (130) as a light source to provide uniform illumination with wider angles. The lead frames (131, 132) of the stem (130) provide an improved structural stability to the LED strip (120, 120') while maintaining a reliable electrical connection between the components of the stem and the LED strip (120, 120'). The utilization of both top-emitting and side-emitting LEDs (320, 330) on the LED strip (120, 120') further allows lights emitted in directions substantially parallel and perpendicular to the LED strip (120, 120')to cover a wide angle of illumination from the LED bulb (100, 200). |
