Today’s HIR (Halogen Infra-Red) incandescent light bulbs produces 75% of the light output of HID headlights at 25% of the cost. They are a single filament bulb with the same base and o-ring style as a 9005 or 9006 headlight bulb. These bulbs attain light levels 75% to 110% brighter than stock as a result of an engineering process by GE that deposits multiple, yet almost invisible, layers of semi-reflective coating on the surface of a specially shaped quartz bulb. This coating reflects a portion of the infrared energy emitted by the filament back onto the filament, causing it to … Continue reading Infra Red Headlights?
First used as status and indicator lamps, and more recently in under-shelf illumination, accent lighting, and directional marking applications, high-brightness LEDs have emerged within the last six years. But only recently have they been seriously looked upon as a feasible option in general purpose or automotive lighting applications. This is an overview of the basic technology which these devices are based. Light-emitting diodes (LEDs) are solid-state devices that convert electric energy directly into light of a single color. Because they employ “cold” light generation technology, in which most of the energy is delivered in the visible spectrum, LEDs don’t waste … Continue reading Light Emitting Diodes
HID stands for High Intensity Discharge which is a term used for many types of lighting systems. Before HID lighting became popular for use in automobiles it was used in industrial and commercial applications. Street lamps, ceiling lights inside large commercial buildings and even some strobe lights are considered high intensity discharge lighting. The technology in high intensity discharge is in some ways similar to fluorescent technology: an arc is established between two electrodes in a gas-filled tube which causes a metallic vapor to produce radiant energy. In this case, however, a combination of factors shifts the wavelength of much … Continue reading High Intensity Discharge Lighting
Some of the first headlights used in cars and trucks after upgrading from candles and lanterns was a housing with built-in filament running on 12v electricity with the name “sealed beam” headlights. It’s called this because unlike today’s modern headlight housings, this entire headlight acted as the bulb. The glass housing was filled with halogen gas and the filament lit up inside just like the filament inside of a modern light bulb. Sealed beam headlights have been used in new manufacturing even today in some heavy machinery and tractor trailer trucks, however less and less frequently. Today people are still … Continue reading Sealed Beam Headlights
