Metal halide lamp for curing chemical compositions

摘要

An arc lamp assembly includes in combination a reflector (42) and a light source (10) which is surrounded by said reflector (42). A dichroic coating on the reflector (42) functions to reflect radiation in the range of about 300 to 600 nm. The light source (10) is an arc lamp which contains a metal halide fill component which includes a mixture of scandium iodide, indium iodide, cesium iodide and sodium iodide, whereby the lamp assembly emits effective amounts of UV radiation to cure selected chemical compositions.
