LED Lights For Tunnels
The thoughts of darkness and danger occur most prominently in the heads of the passengers driving through tunnels. These poorly lit spaces keep one consumed with the fear of accidents constantly. This may make you want the tunnel that you use frequently and even every other tunnel to be fairly lit so that no one has to suffer any mishap.
With LED lighting, it’s possible to visualize tunnels and similar exterior spaces being brightly illuminated. The drivers easily adjust their vision with LED lighting. In absence of maintenance challenges, the light quality stays better with low energy consumption.
One of the primary aims of lighting systems for tunnels and underpasses is to facilitate better visual acuteness for drivers at every time from entrance to exit. Efficient tunnel lighting means the presence of consistent light levels in every spot for safety.
The major issues with tunnels include the corrosive environment, heavy commotion, weather, etc. that exhaust the lights. Sealed and durable lights serve the purpose better thus.
LED lights are the best solution for tunnel illumination. Their major benefit of LED lights is a power efficiency of more than 75% which means that they are way better than conventional lights. Their huge lifespan of around 100,000 hours is another big advantage as against the 50,000-hour life of traditional lights.
The LED lights spread light in the beam pattern and work best with an input voltage of even 100-277V AC. Some of the LEDs designed for tunnels throw beam lighting at a 90-degree vertical axis and 100-degree horizontal axis.
The LED tunnel lights feature the most advanced technologies and durable material as they are designed by the manufacturers to meet special lighting needs for crucial spaces like tunnels, unlike common roads. For instance, lights in the tunnel are exposed to exhaustive fumes, noises, vibrations, and many other harming elements.
Our team focuses on developing personalized lighting solutions for each tunnel after discussing design thoroughly for promising ultimate safety to every commuter.
Different LED Tunnel Lighting Varieties
Surface Mount LED Canopy Light
High Power LED Canopy Lights
The pavilion lighting systems belong to the outdoor light category used in areas that see a high movement of pedestrians and drivers. These are mostly used for industrial purposes where they are used to light up the walkways and aisles. The trademark characteristic of these lights is their perfect suitability for areas bereft of sunlight that remain dark mostly. They can also light up the areas meant for night traffic and windowless buildings.
LED canopy lights can easily replace fluorescent and HID lights for tunnels with their higher efficiency quotient and longer life span. They need no hefty installation or any high maintenance either. They increase the safety quotient of tunnels by securing both entrances and exits along with giving a modern and sleek look.
Vapor Tight Waterproof Fixtures
LED Vapor Tight Lights
Spaces like hallways and large rooms appear better with linear light fixtures. You can choose between the options of 2, 4, or 8 ft long lights. They are waterproof and great for damp, dusty, and wet commercial areas.
These fixtures can increase the lumen output with their clear, frosted, or high impact lenses. The LEDs fixed on linear poles are the best for overhead illumination. These fixtures can be installed in places like tunnels, car washes, cold rooms, and hospitals. They also work great for outdoor spaces that suffer from constant exposure to dust and water.
Retrofit Kits for HID Bulbs
LED HID Retrofit Kits
These lighting kits are better than metal halide and high-pressure sodium bulbs as they come with a low utility cost but give complement the existing fixtures greatly. You can choose from a great variety of wattages and color temperatures to get your perfect retrofit kit. 5000-5500K is the majorly used range of color temperatures because they give brighter and purer white daylight color.
These lighting sources prove greatly economic by easily fitting into the previous fixtures along with boosting light levels and making high energy savings. Specific LED-HID replacement bulbs make better alternatives to the MH or HPS lamps due to wattage consumption as the latter increases the electric bill by consuming a higher amount of power to generate sufficient light. Thus, LEDs are a better and more efficient lighting solution.
Magnetic Strip Retrofit Kit
Magnetic-Strip LED Retrofits
These light kits are the best replacement for fluorescent lamps in tunnels. These kits feature an LED driver, magnetic backings, and light strips in 2, 3, or 4 in number. Some of them even have frosted lenses that give the fluorescent tube look to the strips and diffuse light.
Better efficiency is what makes magnetic strip light kits get ahead in competition with the LED tube lights which means that they give more light with every watt of power. The installation of magnetic strips is also easier since the power only needs to be wired to the driver. Most of these light kits have been rated with a life span of around 50,000 hours which means they can last for approximately 12 years with 12 hours of usage every day.
Lux Levels For Tunnel Lighting
To estimate the lux levels, let’s take the example of a 736m long tunnel that will be divided into 3 portions for different illumination levels. From the entrance till 30m is supposed to be the brightest area and that will take 80 lux for sufficient lighting.
Till 30m ahead is the medium bright area after the brightest area and will need 50 lux of lighting. The next 36m makeup to be the transition area and require only 40 lux of lighting. The middle area of the tunnel can do with 30 lux of average lighting.
In total, about 143 luminaries can light up the whole tunnel as per the divisions. 40 units each can be installed at the entry and exit and 63 units remaining fitted in the middle. A great idea would be to pair this system with intelligent lighting control for brightness adjustment as per natural light.
The selection of the right fixtures majorly depends upon tunnel design as every tunnel isn’t straight in shape. As responsible manufacturers, we ensure that we design fully personalized lights by understanding your requirements thoroughly.
Tunnel Lighting Zones
CIE or International Commission on Illumination governs the science and art of lighting and their publication CIE 88-1900 regarding tunnel lighting dictates:
The required amount of lighting in the tunnel depends directly on the amount of natural light available outside the tunnel. Visual adaptation of the users must occur at some points in the tunnel.
As stated, 5 different areas are very important to be considered while making a lighting plan for the tunnel.
This area lies outside the tunnel and is essentially the portion of the road immediately before the entrance. The tunnel’s interior must get properly visible to the driver in this zone so that any obstacle becomes detected beforehand. Their drive-in must be smooth without any speed reduction.
Thus, the lighting in the entrance area of the tunnel depends upon the driver’s vision adaptability in this zone. The calculation of this visual adaptation can be done by the L20 method dictated by the International Commission on Illumination. This method considers the median luminance taken from factors like environment, sky, and road from an angle of 20 degrees at the point of the line of sight of the driver positioned at the access zone beginning.
This portion gets visible to the driver right before entering the tunnel. The measurement of this portion is equivalent to the stopping distance. The first portion of this zone needs a stable and constant luminance as that depends on the lighting requirements of the exterior portion of L20 and the traffic movement. With the ending of the threshold zone, the lighting levels should also drop down to 40% of the total value.
3. Transition Zone
This subsequent portion has low luminance levels equivalent to the inner zone. The lighting is done sufficiently enough for allowing the driver to view the stopping zone in front of any area lying in the threshold and transition zone.
The lighting level keeps on decreasing with the ending of the span of this zone till it becomes the same as inner zone luminance in depreciation stages of not more than 1:3. This depends on the vision adaptability capacity of the human eye to the environment and the time. The ending portion of the transition zone has a luminance level equivalent to three times the lighting done in the interior portion of the tunnel.
4. Interior Zone
This is the middle zone between transition and exit zones. It is illuminated sufficiently keeping in mind boosted safety levels for passengers and traffic in the day.
This is generally the longest portion of tunnels. Its lighting level requirements depend upon the factors like the density of traffic and speed of the drivers.
5. Exit Zone
While crossing this last portion of the tunnel, the driver’s eyes start adjusting with the lighting levels outside. The lighting in this area shouldn’t be highly contrasted with the exterior portion as a huge difference in luminance levels can be a major problem. In the daytime, the bright light outside the tunnel affects the vision adjustment capacity of the driver as he reaches near to the exit.
The human eye is capable of adjusting instantly to higher light levels from low. However, the adjustment capacities that come into use at the entrance of the tunnel don’t get reversed. This may generate the need for reinforced lighting in situations like lighting contrast to be present behind or in front of the driver when the exit is invisible, exit being used as the entrance as well, emergency cases, operation of maintenance work in the tunnel, and closure of any one portion of the duplicated tunnel. The exit zone can span up to 50m and the lighting levels of this zone must be five times of interior lighting.
