Abstract
An improved lighting fixture for projecting a high-intensity beam of light that is imaged at a distant location, with reduced manufacturing cost and with reduced weight, but greater efficiency. Various structures are disclosed for eliminating infrared light from the projected beam, whereby the fixture's lens can advantageously be formed of a suitable plastic material and be configured as an aspheric fresnel lens or a stepped aspheric lens.
