How to Make Parabolic Astronomical Mirrors.

Dish is 4 feet in diameter, and lights 1000 square feet inside the building, minus the UV rays. Expected lifetime: 20 years. The HSL 3000, a hybrid lighting system developed by Sunlight Direct, carries the actual light of the sun indoors. The system’s 48-inch primary mirror concentrates light into a secondary mirror, which strips away the infrared and ultraviolet components, and directs the visible light into the receiver.
A tracking system has two motors governed by a GPS microprocessor, which can calculate the position of the sun within half a degree. This enables the mirror to follow the sun across the sky like a sunflower, gathering in maximum light intensity throughout the day. “When come in, in the morning and you’re tired, and you’ve got your coffee in your hand and you’re not quite awake, you like seeing the reddish glow… the same type of light as outside.” The Cost-Distance Trade-Off Optical Fiber Research Continues Dr. Hybrid Lighting. By Michael R. Cates n "scriptori" of the Middle Ages, monks sat beneath open windows in the monastery and meticulously copied manuscripts all day long, dipping their quills for the last time when the sun sank beneath the horizon.
The natural light of day made it possible to reproduce the intricate details of their work—and allowed their eyes to survive the nearly timeless daily ordeal. So it has been throughout all of human history: to see clearly, daylight was needed. The modern world is flooded with extra light. In the United States alone our electric lighting bill is about $100 million a day. Lighting costs money—more than most people realize. For many years the DOE has been aware of the national energy problems associated with lighting.
What is Hybrid Lighting? Picture a room with windows. Hybrid lighting is a combination of natural and artificial illumination to be used indoors for all lighting needs. Why Is Hybrid Lighting Needed? Components of Hybrid Lighting Light distribution.
