OPTICAL DEVICE FOR SEMICONDUCTOR BASED LAMP |
| 摘要 |
An optical device for a semiconductor based lamp comprises a semiconductor based light-emitting device and a light-redirecting member. The light-redirecting member has a reflective surface that redirects at least some of the light emitted from the semiconductor-based light-emitting device ambiently, away from the lamp, and into the surrounding environment in divergent lateral and at least partially downward directions, without further reflection. A frosted semi-transparent cover encloses the light-emitting device and light-redirecting member. A gap between the semi-transparent cover and an outer edge of the light-redirecting member passes some of the light emitted from the semiconductor-based light-emitting device upwardly into a surrounding environment. |

1. An optical device for a semiconductor based lamp, the optical device comprising:
a semiconductor based light-emitting device; and a light-redirecting member having a reflective surface that redirects at least some of the light emitted from the semiconductor-based light-emitting device ambiently, away from the lamp, and into the surrounding environment in divergent lateral and at least partially downward directions, without further reflection; the light-redirecting member also passing some of the light emitted from the semiconductor-based light-emitting device upwardly into a surrounding environment. |
