Along with automotive and industrial applications, ballasts with high-intensity discharges find applications in commercial, residential, and agricultural settings as well.

A high-intensity discharge (HID) ballast is a device required by a high-intensity discharge (HID) light (either bus or ballast lighting) to regulate the current and voltage supplied to the bulb during the beginning. The ballast allows the light to be shut off if it fails to start and keeps the temperature stable. HID ballasts are designed to work with any HID light, but they are especially critical when using high-intensity discharge bulbs. The ballast ensures that the high-discharge light does not exceed the maximum allowable level, which might destroy the LED and perhaps the car's cooling system. HID ballasts also supply enough current and voltage during operation to keep halogen lights from failing.

 

In many cases, an outdated ballast may be replaced with a new HID ballast by the car dealer or vehicle manufacturer. Not all vehicles, however, may be fitted with ballast. Because there are several distinct types of HID headlights, their ballasts will also differ. The universal ballast was the first type of ballast. This ballast provides power to both low-voltage and high-voltage bulbs; however, it does not provide power to the headlights.

 

necessitates the installation of a separate ballast. HID ballasts can also assist to minimize the total size of an HID light, making HID systems more compact and transportable. HID ballasts have a wide range of uses and may be utilized in a variety of ways. The phrase "ballast" refers to a variety of technologies, including ballast systems and fuel cells. With the introduction of HID (High-Intensity Discharge) lighting systems in 1970, the term "ballast" was first employed. Since then, high-intensity discharge (HID) ballasts have evolved to accomplish many of the same functions as fuel cells and ballast systems. However, in order to simplify the business and enable more streamlined HID applications, many present rules have been eased so that current ballasts may utilize conventional electrical connections and no new licensing or regulatory barriers are required.

 

The ballast in an HID ballast system is made up of the light source, its photoresistor, and the ballast holder. The photoresistor allows the ballast to power the ballast holder. The ballast holder then allows the ballast's current to be controlled by a current-metering device, such as the IDCI (International Diode Industry Association) Light Emitting Diode (LED) ballast connection, which is widely available for most current ballast applications. The LED ballast connector controls the current so that it does not exceed the IDCI connector's maximum current draw.

 

The present regulatory relaxation also allowed the use of several ballast types in an HID application. Bipolar and linear ballasts are the two most prevalent forms of ballasts. Bipolar ballasts may deliver up to double the current per unit area of a linear ballast. As a result, these ballasts are excellent for applications like lighting control and video surveillance.
