Tunnel Lights

Tunnels are defined as a structure over a roadway that restricts the normal daytime illumination such that the drivers visibility is substantially diminished. Durability and precise light distribution are two essential characteristics of tunnel luminaires. GE LED tunnel fixture uses a high efficient optical system which provides high uniformity and excellent vertical light distribution with reduced glare.

Definitions of Tunnel

• Lav (cd/m²): Luminance of the road surface averaged over the carriageway

• LPD (W/m²): Light Power Density

• Eav (lux): Horizontal illuminance averaged over a road area

• Uo: Ratio of the minimum to average luminance over a defined area of the road surface viewed from a specified observer position (Uo=Lmin/Lav)

• UI: Ratio of the minimum to maximum luminance along a longitudinal line through the observed position on the carriageway (Ul=Lmin/Lmax)

• TI: Measure of the loss of visibility caused by the disability glare of the luminaires of a road lighting installation

• Flicker: Flicker is rapid visible changes of light level

Feature :-

  • 1. Energy Savings
  • It all starts with energy efficiency – and that’s one big advantage that high bay LED lighting has over other types of lighting. Specifically, these lights use less power than other lighting styles, and it’s not uncommon for facilities to save as much as 80% on electric bills compared to lighting alternatives – potentially even more, if this lighting is combined with smart sensors.

    Cost savings, however, is just one big benefit. There are many others.

  • 2. Long-lasting & Cool
  • High bay LED lights last up to 10 times longer than CFL and fluorescent lights. And when they are turned on, they don’t emit any heat. This isn’t just a safety advantage over other types of lights, but because they don’t generate heat, it also saves on cooling costs. In fact, it’s estimated that facilities can save up to 20% on utilities bills, as high bay LEDs will decrease the need for air conditioning.

  • 3. Durability & Sight Advantages
  • We already told you how high bay LEDs are long-lasting, but they’re also very durable – durable to the point where they’re pretty much damage-proof and essentially maintenance-free. Simply put, these lights don’t bust easily.

    LED is also easier on the eyes. Turn on a fluorescent light and it’s bound to flicker – at least, for a little while. Turn on a high bay LED lamp, and you’ll get the light you want immediately. In fact, turn it on and off as often as you want – you won’t notice any problems or flickering.

  • 4. Better Light Uniformity
  • It is a fact that LED lighting distributes light better than others. In fact, many report an 8% increase in light uniformity with high bay LED lighting compared to others. Other benefits of high bay LED lighting compared to fluorescent and CFL lights include lesser light distortion and minimal static buildup.

    One of the main sticking points to installing high bay LEDs in the likes of warehouses is their higher up-front costs. But when you factor in things like energy savings and their lifespan, high bay LED lighting is clearly worth the investment.
