How to install HID conversion kit

As more and more owners install HID conversion kit for their car. Now we share a document about installing HID conversion kit from http://www.gpusi.com/resource/How-to-install-HID-conversion-kit-1367029582.html.

Step 1: Let’s take a look at this diagram below so you will get a clear idea on how to hook up all the parts.

Step 2: Open the hood, locate the back of the headlight to see whether you can remove the bulbs directly. If not, you might have to remove the headlight housing in order to perform the installation.

Step 5: Alright! Now take off the HID bulb from its plastic shell. Again, do not touch the HID bulb glass with your finger, but id you did, you can use rubbing alcohol to clean it.

What is an electronic ballast

An electronic ballast uses solid state electronic circuitry to provide the proper starting and operating electrical conditions to power discharge lamps. An electronic ballast can be smaller and lighter than a comparably-rated magnetic one. The ballast may be “potted” (filled) with a resin to protect the circuit boards and components from moisture and vibration. An electronic ballast is usually quieter than a magnetic one, which produces a line-frequency hum by vibration of the transformer laminations.

Electronic ballasts are often based on the SMPS topology, first rectifying the input power and then chopping it at a high frequency. Advanced electronic ballasts may allow dimming via pulse-width modulation or via changing the frequency to a higher value. Ballasts incorporating a microcontroller (digital ballasts) may offer remote control and monitoring via networks such as LonWorks, DALI, DMX512, DSI or simple analog control using a 0-10 V DC brightness control signal. Systems with remote control of light level via a wireless mesh network have been introduced.

Electronic ballasts usually supply power to the lamp at a frequency of 20,000 Hz or higher, rather than the mains frequency of 50 – 60 Hz; this substantially eliminates the stroboscopic effect of flicker, a product of the line frequency associated with fluorescent lighting (see photosensitive epilepsy). The high output frequency of an electronic ballast refreshes the phosphors in a fluorescent lamp so rapidly that there is no perceptible flicker. The flicker index is used for measuring perceptible light modulation ranges from 0-1, with 0 indicating lower possibility of flickering and 1 indicating the highest. Lamps operated on magnetic ballasts have a flicker index between 0.04-0.07 while digital ballasts have a flicker index of below 0.01.

Because more gas remains ionized in the arc stream, the lamp operates at about 9% higher efficacy above approximately 10 kHz.Lamp efficacy increases sharply at about 10 kHz and continues to improve until approximately 20 kHz. Trials are ongoing in some Canadian provinces to assess cost savings potential of digital ballast retrofits to existing street lights.

With the higher efficiency of the ballast itself and the higher lamp efficacy at higher frequency, electronic ballasts offer higher system efficacy for low pressure lamps like the fluorescent lamp. For HID lamps there is no improvement of the lamp efficacy in using higher frequency, but for these lamps the ballast losses are lower at higher frequencies and also the light depreciation is lower, meaning the lamp produces more light over its entire lifespan. Some HID lamp types like the ceramic discharge metal halide lamp have reduced reliability when operated at high frequencies in the range of 20 – 200 kHz; for these lamps a square wave low frequency current drive is mostly used with frequency in the range of 100 – 400 Hz, with the same advantage of lower light depreciation.

Application of electronic ballasts is growing in popularity. Most newer generation electronic ballasts can operate both high pressure sodium (HPS) lamps as well as metal-halide lamps, reducing costs for building managers who use both types of lamps. Electronic ballasts (digital ballasts) also run much cooler and are lighter than their magnetic counterparts.
