Energy Efficient Lighting

LET'S COMPARE ENERGY-EFFICIENT LIGHTING TECHNOLOGIES HID FLUORESCENT INDUCTION LED HISTORY HID (HIGH DENSITY DISCHARGE) INVENTED IN 1675 BY JEAN PICARD HOW: Picard, a french astronomer, was moving a barometer - essentially a glass tube filled with mercury - and noticed a glow. He'd accidentally eated the first early gas-discharge ancestor of today's HID lamps. JEAN PICARD FIRST COMMERCIAL USE: The first xenon short arc lamps were sold in 1951 by the German company Osram. They were primarily used for movie projection. FLUORESCENT LAMP INVENTED IN 1891 BY NIKOLA TESLA AND DANIEL MCFARLAN MOORE HOW: Thomas Edison's nemesis developed the technology NIKOLA TESLA behind modern induction lamps as early as 1890, and said in an interview, "Surely, my system is more important than the incandescent lamp, which is but one of the known electric illuminating devices and admittedly not the best. However, it was Moore's work that took the technology from its early beginnings into a commercially viable form. DANIEL MCFARLAN MOORE FIRST COMMERCIAL USE: General Electric brought the first "fluorescent lumiline lamps' to market in 1938. INDUCTION LAMP INVENTED IN 1891 BY NIKOLA TESLA AND JOHN ANDERSON OF GENERAL ELECTRIC HOW: Because the underlying technologies are so similar, the early development of Fluorescent and Induction NIKOLA TESLA lamps is identical. However, the first true induction lamp didn't come until 1968 when John Anderson, working for General Electric applied for patents for "Electrodeless Lamps." FIRST COMMERCIAL USE: Philips brought their "QL" induction lighting systems to market in 1990. JOHN ANDERSON OF GE LED INVENTED IN 1927 BY OLEG VLADIMIROVICH LOSEV AND IN 1962 BY NICK HOLONYAK JR. HOW: While working as a radio technician, Losev noticed that the diodes used in radio receivers would glow OLEG VLADIMIROVICH LOSEV when electricity was running through them. His research was published in several scientific joumals, but was all but ignored until the late 1950s. In 1962, Nick Holonyak Jr. developed the first visible red LED while working for General Electric. FIRST COMMERCIAL USE: The Monsanto Company was the first to mass- produce LEDS in 1968, but they weren't used as NICK HOLONYAK JR. sources of general illumination until the mid 2000s. HOW THEY WORK HID - HIGH DENSITY DISCHARGE FLUORESCENT LAMP Electricity regulated by a transformer, ignitor and Electricity regulated by an electronic ballast flows from capacitor jumps between two pieces of metal, one end of a low-pressure tube to the other, through a creating a spark. That spark reacts with gases in the lot of an inert gas, and a little bit of mercury. The bulb to create a long-lasting steady light. mercury gets energized by the electricity, and lets off some of its extra energy as light.

The semiconductor has holes connections inside the lamp, in induction lamps, the in it, and when electrons from the electricity flow acrss electricity regulated by a high frequency generator those holes, they release some of their energy as light. flows from wires outside of the lamp on one side to wires outside of the lamp on the other side.

Fixtures with more light distribution options can allow for more flexible layouts - often reducing the overall amount of fixtures required to get uniform illumination, and therefore the overall energy consumption of the lighting system.
