Latest Patents

One of his latest innovations is a dental curing lamp. This low watt metal halide discharge lamp is designed for use in photo-curing photo-curable compositions. The lamp features an envelope made of light transmissive material, which defines an arc chamber volume. Inside this chamber, a fill of mercury, inert gas, and a metal halide additive, including indium iodide or indium triiodide, is contained. During operation, the mercury and metal halide vaporize, producing radiant energy within the wavelength range of about 400 to 500 nm. The lamp also includes a pair of electrodes with tips spaced apart by a predetermined distance, along with inlead assemblies that connect the electrodes to the exterior of the lamp.

Another notable patent is for a light source that has desired color temperature and chromaticity. This apparatus combines radiant energy from distinct spectral bands to create a light source with predetermined characteristics. It includes a generating source that emits radiant energy from at least two spatial emission regions, each producing energy in a distinct spectral band. An optical directing system is employed to guide the radiant energy to a combining region, resulting in an effective light source with specific color temperature or chromaticity.
