Abstract
A laser landscape lighting apparatus for use in accent lighting applications for landscapes and outdoor venues. In one embodiment, the laser landscape lighting apparatus includes a coherent light source in combination with a diffractive optical element and optionally a diffraction grating wheel. The diffractive optical element may be, for example, a holographic optical element. In some embodiments, the laser landscape lighting apparatus includes a temperature-controlled integral derivative system. In one application, the laser landscape lighting apparatus may project a static or movable star field.
