The inductance of the choke causes a voltage spike when the starter switches off. This is due to the sudden change in current flow and can help achieve the initial spark required to start the fluorescent tube. The fluorescent starter is a time-delay switch that opens after a second or two.

When it opens, the voltage across the tube allows a stream of electrons to flow across the tube and ionize the mercury vapor. The choke controls the current once the tube has been starteas it has a high impedance at the operating frequency of the tube (about 20kHz). It has a low impedance during start-up when the mains current flows through the cathodes and starter at 50Hz.

What is the importance of starter and choke in. This Watt Switch Start Ballast from Tridonic Lighting is a non-dimmable magnetic choke offering an impressive 100hour life alongside low power consumption. Suitable for Pin 2D compact fluorescent lamps this gear requires a capacitor and igniter to operate. This principle of the choke is exploited in lighting a fluorescent tube light. When an AC voltage is applied to a tube light fixture, the voltage passes through the choke , the starter, and the filaments of the tube.

An electrical ballast is a device placed in line with the load to limit the amount of current in an electrical circuit. It may be a fixed or variable resistor. Over Years In Business. Extensive Inventory Available. John Anderson advances the fluorescent lamp by improving the electrodes, inventing a dimmable fluorescent lamp The Bright Stik: The Bright Stik is a type of fluorescent that was developed by John H. Harnden at General Electric.

Buy SWITCH START CHOKES FOR FLUORESCENTS online at International Lamps - a specialist supplier of replacement lamps and lighting control gear. A fluorescent lamp or fluorescent tube is a gas-discharge lamp that uses electricity to excite mercury vapor. The excited mercury atoms produce short-wave ultraviolet light that then causes a. This video explains the theory of how a fluorescent lamp starts and how to connect.

This will enable you to troubleshoot lamp issues on about two-thirds of all tanning beds. A range of battens or starters from trusted trade brands to help fluorescent lights start and reduces flickering while they are on. Unlike incandescent bulbs which have a filament that provides the light, a fluorescent bulb works by ionizing mercury vapour that then emits illumination.

The batten creates a stream of electrons that keeps the ionization process constant and steady. This superior quality Ballast and Choke is widely acknowledged for its renowned feature such as energy efficiency, low maintenance cost, high durability and superior quality. Why is a starter used in a fluorescent lamp?

Why do we use a choke in a fluorescent lamp? Tfluorescent lights use ballasts – the device that limits the amount of current passing through the tube to stop it from overloading. More details To prevent the lamp from taking too much current a fluorescent lamp has to have a choke , which has magnetic inductance. The ECLC502K is a wire wound switch start choke to run linear fluorescents of Watts.

A fluorescent fixture requires a ballast to send the proper amount of electricity to the fluorescent bulbs. In other words, if the current in the lamp increases, the equivalent resistance decreases, further increasing the current. Apple Pay accepted in store. The ballast limits the current and prevents the lamp from self-destruction. Thousands of customer product reviews.

All fluorescent light fixtures consist of at least lamp(s), lamp holders, ballast and internal wiring. Some older types have starters, too. We would love to hear from you, let us know how we can assist.
