A light fixture with coextruded components is disclosed. Embodiments of the present invention provide a solid-state light fixture suitable for use in commercial environments. A light fixture according to example embodiments of the invention includes an LED light source and a coextruded optical assembly. In some embodiments, the reflector portion of the assembly includes a thin skin of reflective material. In some embodiments, the assembly includes an interlocking mechanical interface between the reflector and lens portions of the assembly. In some embodiments, the lens portion of the assembly includes two lens plates. In some embodiments, a longer fixture can be assembled by using two, coextruded portions of an optical assembly, where these portions are adapted to be joined end-to-end. Reinforcing members can be used in the reflector and lens assembly.
摘要:
An elongated lens profile having reverse total internal reflection (TIR) features that improve light extraction when the lens is used in conjunction with a plurality of light emitters. Solid state light emitters, such as LEDs, are arranged proximate to the elongated lens along a longitudinal axis of the lens body. The emitters, which may be grouped in clusters, emit toward a receiving surface of the lens. The receiving surface includes a plurality of reverse TIR features, also disposed along the longitudinal axis. These features may be defined by a series of recessed areas spaced along the longitudinal axis to correspond with the light emitters which can protrude into the negative space created by the recessed features. The recessed features may have more than one shape. The reverse TIR features improve light output uniformity, reducing hot spots along the lens, and improve output efficiency.
摘要:
A lighting device comprising a solid state light emitter and a light mixing element, in which at least ten of light emitted by the emitter that enters the mixing element is reflected within the mixing element, and the mixing element is not larger than 16 mm. Also, a lighting device comprising an emitter and a mixing element comprising first and second regions. Also, a lighting device comprising a light emitter and a mixing element, in which a light exit region of the mixing element has a surface area between about 50% to about 300% of a surface area of a light entrance region of the mixing element. Also, a lighting device comprising a light emitter, a mixing element and a light output shaping element which defines an exit aperture having a dimension that is at least three times a largest dimension of the first light mixing element.
