| 摘要 | A light-directing apparatus for predominantly forward distribution of light from a light emitter having an emitter axis. The light-directing apparatus includes a forward-reflective surface entirely within a lens member positioned over the light emitter. The lens member has an outer surface and an inner cavity including an emitter-light-receiving void and a light-reflecting void which is contiguous with the emitter-light-receiving void and is different in configuration than the emitter-light-receiving void. The forward-reflective surface is in the light-reflecting void in position in the path of light emitted rearwardly. | ||

| 主权项 | 1. A light-directing apparatus for predominantly forward distribution of light from a light emitter having an emitter axis, comprising: a lens member positioned over the light emitter and having an outer surface and an inner cavity including an emitter-light-receiving void and a light-reflecting void which is contiguous with the emitter-light-receiving void and is different in configuration therefrom; and a forward-reflective surface entirely within the light-reflecting void in position in the path of light emitted rearwardly. | ||
