Hid Mercury Vapor

How HID lights work

HID technology is taking over in industry of lights, cars, motorcycles even in aircraft industry. The HID technology has brought some revolutionary solutions such as high-pressure sodium lamps, mercury vapor lamps or metal halide lamps, but all of these technologies are not in such a popular condition as xenon HID light, in first place because of inefficiency despite their accurate final result.

HID lights are using high intensity discharge technology. Lamps of this sort are arc lamps and light itself is obtained once electrons start to jump across two electrodes. These electrodes are made of tungsten, a chemical element known by it`s high melting point and solid physical characteristics. As bulb is containing vacuum inside, light is made each time the electron interferes the ether, in this case, the vacuum. Electricity is being pushed from one side to another and with the effect of a back circuit once it gets pushed to one side it jumps to another one, and creates light as beam of electrons cuts through the vacuum. Metal salt particles together with atmospheric gas xenon, are trapped inside the bulb which is made out of alumina or fused quartz. Once electricity is sent to HID light, gas assists in the process of electrons `jumping` from one point to another and creating the light. This is part where metal salt particles are coming on the stage as they give light the super boost. As these small particles begin to heat up they will eventually turn into the plasma, once they hit the critical temperature necessary to solve the process which is called the temperature of evaporation. This plasma will make its way into the HID bulb creating such an effect which you would call a five hundred times higher light intensity, comparing to standard halogen based lights. This technology uses more lumens than standard lights, using less energy in same process. Sodium based lamps which are using high-pressure technology has yellowish light as a result of the process while metal halide lamps are producing highly desired white light but this technology is way to inefficient and needs to be developed further more. HID lights are normally made of two igniters, two ballasts and two bulbs while the latest models are used as igniters with ballasts.

 Major advantages of this type of light are in very bright light that can go in different colors such as blue, red, white or purple, high level of efficiency or no heat produced. Light produced by xenon HID lights based on 35 watts will exceed halogen based lights that were made out of 150 watts. One of negative effects of these lights is glare effect on the other drivers. This effect can be really uncomfortable or even fatal in crucial situations as light of radius that xenon HID light offers can totally turn blind driver from another direction causing him distracted on higher point or even cause a car crash. This is the main reason why HID conversion kits have been abandoned by the Institute of Transport and Traffic.
