Light-directing apparatus with protected reflector-shield and lighting fixture utilizing same
DCFirst Claim
1. A light-directing apparatus for off-axial preferential-side distribution of light from a light emitter having an emitter axis, comprising:
- a lens member positioned over and fully enclosing the light emitter and having;
an inner surface defining an emitter void and a shield-receiving void which is on a non-preferential side of the lens member, the shield-receiving void being different in configuration than the emitter void and including a shield-contacting inner-surface portion; and
an outer surface; and
a shield member in the shield-receiving void in position in the path of light emitted toward the non-preferential side, the shield member having a back surface configured to engage the shield-contacting inner-surface portion.

Abstract
A light-directing apparatus for off-axial preferential-side distribution of light from a light emitter having an emitter axis, including a lens member positioned over the light emitter and a shield member. The lens member has a proximal end substantially transverse the emitter axis and an outer surface which may be configured for refracting light from the emitter. The shield member may be snugly received in a shield-receiving void of an inner surface of the lens member. Alternatively, the shield member is embedded by the lens member having been molded thereabout. Another aspect of this invention is a lighting fixture utilizing such light-directing apparatus.

16. A lighting fixture with a plurality of light emitters spaced from one another on a mounting board, each light emitter having an emitter axis substantially parallel to the axes of the other light emitters, and light-directing apparatus positioned over the light emitters for off-axial preferential-side distribution of light from the emitters, the light-directing apparatus comprising:
-
a plurality of lenses each positioned over and fully enclosing a respective one of the light emitters and each having; an inner surface defining an emitter void and a shield-receiving void which is on a non-preferential side of the lens, the shield-receiving void being configured differently than the emitter void and including a shield-contacting inner-surface portion; and an outer surface; and a plurality of shield members each disposed within the shield-receiving void of a respective one of the lenses and each in position in the path of light emitted from its respective light emitter toward the non-preferential side, each shield member having a back surface configured to engage the shield-contacting inner-surface portion of the corresponding lens. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
