    摘要： A lens for a primarily-elongate distribution of light from a light emitter having an axis with a lens base being substantially normal to the axis. The lens includes a substantially-rectangular emitter opening to a cavity defined by a refracting inner surface. The lens further includes a refracting main output surface transverse the axis and a reflecting surface extending from the lens base away from the axis outwardly of and around the inner surface. The reflecting surface receives substantially all forward and rearward light and a portion of lateral light refracted by the inner surface for total internal reflection (TIR) toward the main output surface which refracts such light into the elongate distribution. The lens is configured such that the other portion of the lateral light exits the lens away from the axis for wide-angle distribution along the elongate distribution.

    摘要： Color mixing optics for a multi-color LED lamp comprise an outer reflector having a paraboloidal surface of revolution and a total inner reflection (TIR) lens having an outer contour with a paraboloidal surface of revolution. The outer reflector and the TIR lens are centered around a common center axis. A common focal point of the outer reflector and the TIR lens is provided for placing a LED assembly. Such LED lamps produce uniform color throughout the entire light beam while the outer dimensions are such that the optics fit into conventional lamp housings.

    摘要： A light fixture includes a housing, a light-emitting element, and a lens extending over the light-emitting element. The housing includes a support surface, and the light-emitting element is coupled to the support surface. The lens includes a refractor portion having an inner surface and an outer surface. The inner surface is positioned proximate the light-emitting element. The inner surface is oriented at an angle such that the light generated by the light-emitting element exhibits total internal reflection within the lens until the light reaches the outer surface.

    摘要： An optical element for influencing a light emitted by a light source, having a front side facing away from and a rear side facing the light source. A recess for the input of the light is formed on the rear side, and a deflecting surface region is formed. On the front side, a frontside surface region is formed. First light beams (L1) entering the optical element via the recess, are totally reflected at the deflecting surface region and exit the optical element via the front-side surface region. The front-side surface region causes the second light beams (L2) of the light, which enter the optical element via the recess and then hit the front-side surface region directly, to undergo total reflection. High intensity light beams from the light source can be distributed onto a larger region reducing the maximum luminance of the light emitted via the front-side surface region.

    摘要： A total internal reflection (TIR) lens can have a back surface tapered to provide total internal reflection of light toward the front surface. The front surface can have a stepped shape defining a cavity that extends into the lens body, with a width of the cavity increasing toward a front side of the lens. The front surface can further have a convex central surface segment that extends from the front surface within a central portion of the cavity. A peripheral cover member can be formed integrally with the lens body, with a front surface extending laterally outward from an outer edge of the front surface of the lens body and a back surface extending laterally outward from an outer edge of the back surface of the lens body.

The lens includes a light incident surface and a light extraction surface, a plurality of first recesses being defined in the light extraction surface, a plurality of second recesses being defined in the light incident surface. Each first recess has a pair of first inclined surfaces, and an angle between the first inclined surface and a plane where the light incident surface located is larger than or equal to a critical angle of total reflection of the lens. Each second recess has a pair of second inclined surfaces, and an angle between the second inclined surface and the plane where the light incident surface located is less than or equal to the angle between the first inclined surface and the plane where the light incident surface located.
