LED lights used in Railway

Create professional track lighting according to industry characteristics, meet the “safe, efficient, energy-saving, and comfortable” rail transit lighting needs, improve site energy efficiency management, reduce station operation and maintenance management costs, and improve the lighting comfort experience in the station.

LED Applications in Railway Signals: Wavelength and Intensity vs Temperature Variation

Although LEDs have been present since the 1960s, considerable levels of light brightness have only lately been achieved. LEDs are appropriate for safety signals for rail- way, road traffic, and other applications in stationary transportation because of their power, energy economy, maintenance savings, and impact resistance durability.
The conventional systems will be replaced by the new signaling systems because they have better maintenance and failure time characteristics.
Traditional signals use one of the two procedures listed below to create their illuminated aspects:
tungsten halogen lamps, which emit nominally white light and with colored filters that develop the desired color; tungsten lamps, which emit nominally yellowish-white light and with various combinations of colored and/or clear focusing lenses, which collect some of the light from the lamp, filter it into the appropriate color, and focus it into the required angle.

The main disadvantages of this technology are:

(1) the short lifetime of the light sources (about six months);

(2) the inefficient conversion of electric input power to optical power; and

(3) the significant chance of signal failure.

Particularly, the conventional light source catastrophically fails. Therefore, regular maintenance and control interventions are required to ensure the appropriate safety standards. It takes a lot of effort to change filament lights on a regular basis, which drives up maintenance expenses. This may be especially high for a railway signal that may be some distance from an accessible position along the railway and that need at least two personnel members (for safety). Reduced maintenance costs are the key drivers for the replacement of filament lighting on the railway. The major benefit of using LEDs is the decrease in power consumption and resulting energy savings. The replacement of filament lamp traffic signals also results in less maintenance and increased readability.
In any event, using classic lamps has the advantage that the brightness and color of the radiation they generate seem to be constant and unaffected by temperature fluctuations. On the other hand, the current generation of LED technology has the flaw that the dominant wavelength and intensity are strongly temperature sensitive.
Heat has an impact on the performance and dependability of both the lighting fixtures and the LEDs, making thermal management one of the key areas that has to be addressed. The junction temperature affected the optical characteristics of LEDs.

The work of lighting railroad infrastructure may be difficult. During the design process, compliance, glare, safety, and visibility must all be carefully taken into account. Railway illumination is a specialty of Advanced Lighting Technologies. We provide a broad variety of lighting solutions that are ideal for rail applications and have already given energy-efficient lighting solutions to some of Australia’s leading railway operators.

Track – Waterproof outdoor  LED Light

It’s essential for maintenance personnel and train drivers to have clear track view. We provide a specialized selection of flood and area lighting options that are designed to fit rail situations.

Platform – Wall Pack Lights

Using a practical, aesthetically pleasing lighting system that complies with illumination, glare, signaling, and CCTV regulations, station platforms may be safer and more compliant.

Internal Structure – Spot Lights

No of the time of day, commuters should feel secure utilizing railway and light rail stations. A bright setting might enhance a person’s feeling of security.
