LIGHT-EMITTING-DIODE-BASED LIGHT BULB |
摘要 |
A lighting apparatus includes a first substrate, a plurality of first light-emitting devices disposed on the first substrate, a second substrate disposed over the first substrate, and a plurality of second light-emitting devices disposed on the second substrate. A reflective surface is disposed between the first substrate and the second substrate. The reflective surface is configured to reflect light emitted by at least some of the first light-emitting devices in a direction that is at least partially toward the first substrate. The reflective surface has one of: a saw-patterned side view profile, or a curved side view profile that is free of having an inflection point. |

1. A lighting apparatus, comprising:
a first substrate; a plurality of first light-emitting devices disposed on the first substrate; a second substrate disposed over the first substrate; a plurality of second light-emitting devices disposed on the second substrate; and a reflective surface that is disposed between the first substrate and the second substrate; wherein: the reflective surface is configured to reflect light emitted by at least some of the first light-emitting devices in a direction that is at least partially toward the first substrate; and the reflective surface has one of: a saw-patterned side view profile, or a curved side view profile that is free of having an inflection point. |
