摘要:
A lens 10 comprises a first surface 12 and a second surface 14. The first surface 12 is provided with a plurality of horizontal, linear Fresnel lenses 16 and the second surface 14 is provided with a plurality of horizontal pillow optics 18. In the lens 10 the horizontal, linear Fresnel lenses 16 of the first surface 12 provide vertical refraction of light from a central axis sufficient to collimate light from a point to within ±70 degrees of horizontal and the pillow optics 18 of the second surface provide horizontal spread of the collimated light to ±25 degrees from the medial plane.
摘要:
Disclosed herein are apparatus, method, and system for producing a customizable composite beam from a plurality of solid state light sources. Each light source is associated with individually adjustable fixture components which allow for a variety of lighting needs to be addressed. The composite beam is a collective of the beam projected from each adjustable component/light source combination; each individual beam being of customized shape or standard shape.

摘要:
Improved lighting devices and methods are provided. In many embodiments, the devices and methods provide the capability to change a spot of light projected onto a target surface. In other embodiments, the devices and methods are fixed-focus. In one embodiment a lens can have a lens body with anterior and posterior surfaces. The anterior surface can be adapted to receive light from a light source. The posterior surface can have a central portion and a peripheral portion. Some of the light from the light source can pass through the lens body and exit the central portion of the posterior surface via refraction. Some of the light from the light source can pass through the lens body and exit the peripheral portion of the posterior surface via both refraction and reflection at various surfaces of the lens.
