HID Technology: Perfect Option Of Lighting Transformation In

Automobiles

BY- XTRALIGHTShttp://www.xtralights.com

High Intensity Discharge

(HID) is the most recent

lighting technology in which

light is produced by means

of an electric arch linking

tungsten electrodes present

inside a crystal clear or

semi-transparent fused

quartz or alumina arch tube.

What Is HID?

The normal conventional bulbs used to produce enormous

amount of heat due to burning of filament.

This led to the introduction of HID technology in which

filament was replaced with a gas capsule.

The light is released from an arch emitted between two

intimately placed electrodes present in the small quartz

glass.

The biggest advantage that these light forms is that they

produced bright light.

How HID Technology Emerged?

When current passes through the metal vapor light is generated.

The free electrons collide with an atom in the vapor form

knocking the atom present at the higher orbit for a short time.

These electrons are displaced and then they return to their

former orbits releasing quantum of radiation.

The wavelength of emission depends on the energy zone of the

distressed electrons and also on the kind of metal vapor used in

the arch tube.

Complete Process Of HID Lighting Technology?

Mixture of mercury, argon and

other metal halide salts is

preferred because these metal

halides increase lumen and

augment the light color.

The gas inside the bulb that

facilitates the arch's initial hit

which warms up and evaporates

the metal salts and forms plasma

that significantly boosts up the

light formed by the arc and

decreases its energy

consumption.

Lights or bulbs working on HID

technology are a kind of arc lamp.

Different Types Of HID Bulbs

HID Lights Color Temperature

White Light: Color of the HID based bulbs and lights are more

similar to the color temperature of natural daylight. This can

also be defined using a single term "correlated color

temperature“. Classic color temperatures are 2800K of

incandescent, 3000K of halogen, 4100K of SP41 fluorescent or

cool white, and 5000K of daylight-imitating fluorescent colors.

Increased Light Output: The lumen per watt (LPW) efficiency

is approximately 8 times that of an incandescent light.

Long Service Life: The life of the HID lamp/light is 3 to 5

times as long as a halogen bulb. In normal usage, an HID bulb

lasts further than one thousand ignitions.

Pathways

Applications Of HID LightsThe basic purpose for the development of this HID technology was to use this

technology when high level of light is required. It is the best option when you are

looking for both the energy and light efficiency. The areas where the HID lamps

are classically used are:

In DLP or LCD projection televisions, Ultra-High Performance (UHP)

HID lamps are used. Using them for the proper growth of the plants

which actually need high levels of direct sunlight in their natural

habitat is the best example. The reason is that HID lamps, high-

pressure sodium and metal halide are the most common source of

indoor gardening.

HID lamps are also used in high-performance bicycle headlamps as

well as other lights. These are employed even in flashlights because

they produce an enormous amount of light per unit of energy

consumed. Aircrafts and underwater diving are also the areas where

HID lamps are used.

The relationship between HID technique and automobiles is quite

strong which is difficult to express in words.

All latest cars launched by any of the existing brands have HID

based light forms especially headlights.

The principal benefit is that the light produced by the HID

headlights is 300 percent brighter than the normal light forms.

These are water, weather, vibration, shock and UV Rays protected.

There is a brilliant shine in these HID based lights.

HID based bulbs are also available and hence people who cannot

afford buying lights are purchasing HID bulbs.
