Abstract
An omnidirectional LED lamp is designed with a complex lens covering a light source. The light source is a light emitted diode chip or a light emitted diode lamp or package. The complex lens is composed of a top center lens, a wing lens, and a tube lens. The top center lens modifies the light beams to shed lights above the lamp, the wing lens surrounds and connects with the top center lens to modify the light beams to shed lights on side bottom of the lamp, and the tube lens is configured under the wind lens and connects to the wing lens to modify the light beams to shed lights on side top of the lamp. The complex lens modifies light beams from a light source to shed light on full directions.

An omnidirectional light emitting diode (LED) lamp, comprising:
- an LED;
- a complex lens, which has a unitary construction and comprises:
- a top center lens, refracting a first group of light beams from said LED for a first fan-out area to illuminate top spaces of said lens;
- a wing lens, surrounding and connected to said top center lens, reflecting a second group of light beams from said LED for a second fan-out area to cover side bottom spaces;
- and
- a tube lens, on bottom of said wing lens, refracting a third group of light beams from said LED for a third fan-out area to cover side top spaces;
- wherein said top center lens is a concave lens, said wing lens is a total internal reflection lens, and said tube lens is a concave lens.
A complex lens, comprising:
- a top center concave lens;
- a wing lens, having a property of total internal reflection, surrounding and connected to said top center lens;
- and
- a tube concave lens, on bottom of said wing lens;
- wherein said complex lens has a unitary construction.
A light emitting diode (LED) lamp, comprising:
- a glass bulb;
- and
- at least one omnidirectional LED lamp enclosed inside said glass bulb, said LED lamp comprising:
- an LED;
- a complex lens, which has a unitary construction and comprises:
- a top center lens, refracting a first group of light beams from said LED for a first fan-out area to illuminate top spaces of said lens;
- a wing lens, surrounding and connected to said top center lens, reflecting a second group of light beams from said LED for a second fan-out area to cover side bottom spaces;
- and
- a tube lens, on bottom of said wing lens, refracting a third group of light beams from said LED for a third fan-out area to cover side top spaces;
- wherein said top center lens is a concave lens, said wing lens is a total internal reflection lens, and said tube lens is a concave lens.
