OMNI-DIRECTIONAL REFLECTOR COMPRISING A FRUSTO-CONICAL SURFACE FOR A!LIGHT-EMITTING DIODE |
摘要 |
An optical element for a lamp or lighting apparatus having at least one light emitting diode (LED) as a light source is provided. The optical element is positioned proximate to the LED and receives light rays therefrom. In turn, the optical element distributes the substantially unidirectional light output from the LED into an omnidirectional output with a controlled variance in light intensity at different directions about the LED. A diffuser can also be used around the optical element and LED to provide further distribution of the light rays by e.g., light scattering. |
