What is the light control gear?
Ballast or control gear, is ‘Part of the control equipment of fluorescent or discharge lamps, used to stabilise the current. A modern electronic ballast working at high frequency consumes about 30% less current, and can be used to regulate or dim the lamp output.
What is control gear in a LED?
Control gears stabilise the current and regulate the light output of an LED light or group of lights. They also contribute to higher efficiency and ensure the LED lights continue to function correctly by reducing flicker and ensuring stable energy consumption.
Is a device used to control the voltage in the lamp and Stabilise the current in fluorescent tube?
A ballast is a device that is used with fluorescent and other discharge lamps to provide the required current and voltage. The primary function is to provide the lamp with high voltage and/or cathode heating during start-up, and then to stabilise the arc by limiting the electrical current to the lamp.
What is ballast in lighting?
ballast – A device required by electric-discharge light sources such as fluorescent or HID lamps to regulate voltage and current supplied to the lamp during start and throughout operation.
What is the difference between ballast and aggregate?
The general rule of thumb when making concrete is to use 4 parts aggregate, 2 parts sharp sand and 1 part cement and water. The bit that is aggregate and sharp sand is collectively known as ‘ballast’ and is typically sold in ready-mixed bags.
What is rail and its types?
There are three types of rails: Double-headed rails. Bull-headed rails. Flat-footed rails.
What is 10mm ballast used for?
10mm ballast is a mixture of Sharp Sand and 4/10mm shingle used in concrete production making levels and bedding.
What is the function of the LED light control gear?
Lighting Control Gear performs a number of functions; limiting and stabilizing the current in an electrical circuit, ensuring continuous operation of the lamp, providing ignition voltage, reducing/eliminating flicker and noise, reducing energy consumption and increasing efficiency.
What is a control gear for a gas discharge lamp?
A gas discharge lamp such as the fluorescent, metal halide, mercury vapour and sodium lamp, requires a control gear to ignite it and keep a regular flow of electric current inside it. There are several types of control gears, each having its own advantages.
What is a lighting control system?
A lighting control system makes the repeated task of adjusting lights much simpler . Automated lighting changes on its own, and convenient keypads can be used to change the lighting anywhere in the home quickly and simply . The combination of these features in a lighting control system makes any home more convenient and its lighting more elegant .
How does light control work?
Lighting controls are input/output devices and systems. The control system receives information, decides what to do with it, and then adjusts lighting power accordingly. Here we see a basic lighting circuit (switch leg). Power travels along the circuit to energize a group of lights. This lighting system supplies illumination.
