Light-directing apparatus with protected reflector-shield and lighting fixture utilizing same

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.

2. The light-directing apparatus of claim 1 wherein the outer surface is configured for refracting light from the emitter in a predominantly forward direction.

3. The light-directing apparatus of claim 1 wherein:

the lens member further includes a proximal end transverse to the emitter axis and defining an opening to the inner cavity; and

the emitter-light-receiving void extending from the opening and facing the emitter.

4. The light-directing apparatus of claim 1 wherein the forward-reflective surface is a front surface of a shield member disposed in the light-reflecting void.

5. The light-directing apparatus of claim 4 wherein the reflective front surface of the shield member is non-planar.

6. The light-directing apparatus of claim 5 wherein the reflective front surface of the shield member has a plurality of sections angled with respect to each other.

7. The light-directing apparatus of claim 6 wherein the sections are each substantially planar.

8. The light-directing apparatus of claim 4 wherein the shield member includes a shield portion and a base portion.

9. The light-directing apparatus of claim 8 wherein:

the lens member further includes a proximal end transverse to the emitter axis and defining a shield-insertion opening;

the shield portion extends from the base portion into the path of light emitted rearwardly;

the base portion extends from the shield portion away from the light emitter at the proximal end of the lens member; and

the reflective front surface is on the shield portion.

10. The light-directing apparatus of claim 1 wherein the light emitter comprises an LED.

11. The light-directing apparatus of claim 1 wherein:

the light emitter is an LED package including at least one LED and a primary lens over the LED;

the lens member is a secondary lens placed over the primary lens; and

the forward-reflective surface generally faces the primary lens.

12. The light-directing apparatus of claim 11 wherein the lens member includes an outward flange around the opening(s) at the proximal end.
