Ultraviolet infrared filter
View Patent ↗A two-dimensional wedge shaped UV and IR filter is formed by or substantially same size pieces of glass forming a two-dimensional wedge. The wedge reflects radiation in four different directions.
1. A method, comprising:
projecting high-intensity light along an axis, said high-intensity light being from a source having at least 700 W of output; and
filtering the high intensity light along said axis, to remove both ultraviolet and infrared along said axis, said filtering comprising reflecting said radiation in at least multiple different directions simultaneously using a single filter, where said filtering provides identical amounts of said ultra-violet and infrared filtering characteristics in each of said multiple directions, wherein said filtering is carried out using a number of separate surfaces that come together at an apex, and further comprising a hole at said apex, wherein said hole is at an area of a shadow created by said source in a direction of facing.
2. A lighting device, comprising:
a light source operating to produce high-intensity light along an axis, said high-intensity light being from a source having at least 700 W of output; and
a light filter with multiple different surfaces, where each of said multiple surfaces face in a different direction, and said surfaces are located along said axis, said light filter filtering to remove both ultraviolet and infrared along said axis, by reflecting said high intensity light in at least multiple different directions simultaneously using a single filter, and where each of said multiple surfaces provides identical amount of ultraviolet and infrared filtering, wherein each of said multiple surfaces are separate materials that come together at an apex, wherein there is a hole at said apex, and wherein said hole is at an area of a show created by said light source.
