Ballasts for lamps and LEDs


Ballasts for lamps and LEDs

Fluorescent tubes, as well as other types of discharge lamps, are not suitable for direct connection to the power grid. The ballasts are then used in combination with the starters to light the lamps. Conventional fluorescents and discharge lamps do not work without ballasts and must always be connected to them. For fluorescent tubes, the third generation of ballasts is currently used. Also know that even with LED technology, we also use "ballasts" called drivers in this case.

In general, there are 2 types of ballasts:

  1. ·         Conventional ballasts, and the economic version
  2. ·         Electronic ballasts


Conventional ballasts:

Since 2017, only energy class A2 ballasts are installed. For the next few years, conventional ballasts may no longer be sold in the EU because they do not meet the growing requirements for energy efficiency. Like incandescent bulbs, these devices will tend to disappear in favor of much more efficient electronic ballasts.

Starter:

Conventional ballast consists of a coil. In simple terms, this coil will make sure that the fluorescent tube is served by an operational power of 50-100V. It is also necessary to use a starter in combination with the ballast to preheat the fluorescent tube (orange color at both ends of the tube). Then, the current is interrupted for a short period of time, creating a voltage point of about 1000V in the coil. Suddenly, the gas in the tube will glow. In addition, the characteristic flicker of light in the fluorescent tubes is due to the choke.

Electronic ballasts

The technology that currently prevails is electronic ballasts. In a completely different register, electronic ballasts operate with fluorescent tubes T8 and T5 and discharge lamps. These start the device without choke and manage the ignition through the integrated electronics. Inside, a powerful voltage is generated through the coils and capacitors, allowing the gas to light up.

For what use high bay LED?

For what use high bay LED? What are the stakes for lighting large outdoor spaces? To be properly lit, it is important that department stores, factories or warehouses have powerful lighting to ideally cover all the space (vertical and horizontal). Most of the time, these areas have a high ceiling. This is why the luminaires used must be powerful, and the light must have a high color rendering to allow to see the products in the best way possible. In addition, employees who work there must be able to practice in secure areas. So, the solutions used for this type of application have been discharging lamps or sodium vapor lamps. However, innovations have been made with LED technology compared to traditional lighting. Here are the issues to highlight when illuminating these areas: ·          The life of the luminaires must be as long as possible ·          Use as little energy as possibl...

LED lighting for museums

LED lighting for museums For museums, the use of LED lighting is more interesting from day to day . In fact, works of art must be kept in a cool, dry place in the dark to protect them from damage. However, to ensure that museum visitors continue to enjoy the works, the ideal lighting is needed. Lighting in museums should always serve two purposes: 1.        General Illumination - Sufficient brightness throughout the room 2.        Accent lighting - accentuate brightness on different works/objects Which LED lighting for museums? Showcase lighting Some objects can be exhibited in showcases with appropriate lighting. For windows without their own illumination, the ceiling lighting should always focus on the window, to prevent any reflection. In addition, it is recommended in this case to use anti-reflective lenses and dimmable (dimmable) lights. Ceiling lighting. Lighting for objects Som...
