摘要： Optical elements with small increments in average density are formed in a substrate by laser micromachining using a variable aperture and a pattern mask set of pattern masks each having of shape-defining elements whose density differs among the pattern masks in first density increments. A laser light beam passes through a combined mask formed by the variable aperture and one pattern mask selected from the pattern mask set. The variable aperture controls beam size and the pattern mask spatially modulates its intensity. A focusing element focuses light from the combined mask on a small averaging region of the substrate. Different combinations of the size of the aperture mask and the selected pattern mask are used in combination at respective averaging regions of the substrate. The resulting average densities of the optical elements vary among the averaging regions in increments that are small compared to the first density increments.

摘要： A light bulb includes a base, a light source and a light guide having opposed major surfaces and a light input edge that receives light from the light source, the light propagating along the light guide by total internal reflection and the light guide including a light output region on one of the major surfaces. An optical adjuster has a first region having a light modifying characteristic and a second region. The optical adjuster and light output region are variably positionable relative to one another to selectively apportion light emitted from the light output region between the first region and the second region, the light apportioned to the first region being modified by the light modifying characteristic thereof so that light output from the light bulb is modified based on relative positioning of the optical adjuster and the light guide.

摘要： A lighting assembly includes a light guide and light source. The light guide includes light input regions, at least one of the light input regions associated with an optical modifying characteristic, and the light guide is configured to propagate light by total internal reflection. The light source is located adjacent the light input regions. The light source and light input regions are variably positionable relative to one another to vary a location at which light is incident on the light input regions such that light emitted from the light source is selectively apportioned between the light input regions. A characteristic of the light output from the lighting assembly is modified based on the optical modifying characteristic of the at least one of the light input regions and the relative positioning of the light source and the light input regions.

摘要： A light bulb includes a base for mechanically mounting the light bulb and for receiving electrical power, a light guide, and a light source that directs output light into the light guide. The light source includes a light emitting device that emits light, and a variable spectrum adjuster that is variably positionable relative the light path of light emitted by the light emitting device. The spectrum adjuster includes a region of continuously-variable spectrum-adjusting material, usable for adjusting the spectrum of light passing through the spectrum adjuster. In some embodiments, the spectrum adjusting material is a color-attenuating material, such as a filtering material. In other embodiments, the spectrum-adjusting material is a wavelength-shifting material, such as a phosphor, or another suitable type of material that shifts the wavelength of light incident.
