Question 1

What should be paid attention to in tunnel lighting project?

Accepted Answer

For each step of a tunnel lighting project, from the simplest to the most complex, certain criteria and standards must be followed to guarantee that drivers are given with a pleasant lighting effect. A significant distinction between tunnel illumination and conventional street lighting is that as cars enter or exit a tunnel, visual brightness levels shift. As a result, the lighting should be adjusted. Indeed, illumination needs for tunnel lighting projects might vary significantly depending on the tunnel's various zones.

Diverse lighting needs exist for the tunnel's several illumination zones:
Tunnel lighting is classified into five zones based on their relative brightness: entry zone lighting, threshold zone lighting, transition zone lighting, interior zone lighting, and exit zone lighting. Each zone has its own distinct illumination needs.

Lighting in the access zone

The approach segment is intended to provide drivers with a good view of the tunnel portal conditions as they prepare to enter the tunnel, as well as to acclimatize to the tunnel entrance's brightness.
The brightness outside the tunnel is much greater than the light within during the day in this zone of the tunnel. If the tunnel is sufficiently lengthy, cars will encounter a black hole. Additionally, if the tunnel is really short, a black frame will emerge in front of the drivers. When you enter a tunnel, you are traveling from a brighter environment to a darker one. Without adjusting the lighting scheme, a visual contrast will result. Drivers may need to adjust to their new visual surroundings for a period of time. That is, the eyesight must adjust over a period of time before the tunnel's circumstances can be perceived. While the adaption period is likely to be brief, it is very risky for driving motorists. so It is normally suggested to utilize a moderately strong tunnel light in the access zone to assist drivers in acclimating to the tunnel portal's conditions in advance.

Zonal illumination at the threshold

The threshold zone is the tunnel's initial portion. Generally, this zone has a substantially greater rate of traffic accidents than the rest of the tunnel. The threshold zone is a part of the tunnel when drivers transition from a normal driving environment to a tunnel-specific driving environment.
How to avoid the negative consequences of this mutation section becomes the focal subject of lighting design in this threshold zone. What must be done quickly is to eliminate the black hole vision phenomena that occurs when motorcyclists approach tunnels during the day. The purpose of this lighting standard is to maintain the drivers' eyesight state.

Transition zone lighting

Between the threshold zone and the interior zone, there is a transition zone. As previously stated, we resolve the "black hole" issue by altering the brightness of the tunnel entrance, however this introduces another issue of luminance contrast. The issue is that the threshold zone has a high level of illumination while the inner zone has a low level of illumination. Drivers have the same visual adaption challenges as cyclists. As a result, the lighting design for this zone is centered on methods for resolving the perspective adaption issue. It's just an issue of scale, a lower contrast between light and dark.
When the vehicle enters the transition zone from the entrance during the day, it is required to organize and install tunnel lights with varying brightness levels to enhance the driver's visual comfort. The transition zone's brightness should gradually diminish.

Zone lighting interior

The tunnel's inner zone is located far from the natural illumination's effect region. Only the tunnel illumination impairs the driver's eyesight. Drivers have completed the adaption procedure after they have passed through the threshold zone and transition zone. The inner zone's lighting objective is to maintain the stability of prior visual conditions in order to enhance security. As a result, this zone just needs to offer an adequate degree of illumination and does not need to be altered.

Lighting for exit areas

There are two scenarios that occur when cars exit the tunnel.
They are transitioning from a darker to a brighter part throughout the daylight. At night, though, the opposite is true. At the tunnel's departure zone, there will be a bright exit zone during the day, creating a high glare for cars, impairing their ability to observe road conditions and increasing their risk of traffic accidents. On the other hand, if you escape the tunnel at night, the exit becomes a black hole. For motorcyclists, it is difficult and inconvenient to observe the path and any hazards. As a result, the lighting design for this tunnel may have a dimming feature to enable automated dimming in response to the changing daylight environment outside the tunnel.

Question 2

How to choose led tunnel light?

Accepted Answer

Reasonable stability

If the tunnel is not lighted, it is completely black, save for the entrance and these two particular locations that presumably get some natural light.
As a result, it's easy to imagine how dangerous it is for cars to travel through tunnels or underpasses without illumination.
Additionally, when the provided illumination is not steady, it creates a visual disruption for motorists.
It is exactly because safe driving is a serious issue of life and death. As a result, we recommend prioritizing the performance of a stable led tunnel light.

Long working lifetime

Longer useful life results in fewer replacements and lower costs and consumption of extra personnel and material resources. This will provide you with a substantial edge when competing for the desired lighting project.
Additionally, there is nothing wrong with selecting tunnel lamps with a longer lifetime. Because practically everyone prefers and tends to pick a high-quality product, the serving duration of a product becomes, to a certain degree, a reflection of whether a product is excellent or terrible.

High-efficiency lighting

When embarking on a lighting project, there are always a plethora of schemes to choose from. However, you must ensure that it adheres to the minimum degree of brightness. At the very least, it should meet the building site's illuminance requirement. Generally, under the same set light level need, the quantity of lighting fixtures desired by the planning project and the brightness of luminaires seem to have a negative link.
The objective is to have something that serves as a guide.
Lighting efficacy is a critical guiding element in assisting you in choosing the most appropriate and efficient lighting solutions.
Increased lighting efficiency results in fewer fixtures being required, lower installation costs, a smaller project budget, and safer lighting service.

Uniformity

Additionally, homogeneity is a critical aspect of illumination that must be addressed in designing this working environment.
The more symmetrical the light spreads, the better the visual effect. Uniform lighting has a tremendous impact on boosting driver security and significantly lowering the accident rate. As a result, homogeneity is seen as a critical component in a variety of industrial lighting applications. Likewise, for tunnel illumination.

Anti-glare

Glare is an unregulated and overwhelming amount of light.
Glare from light fixtures creates an unsafe driving environment and makes drivers feel uneasy and anxious as a result of visual disturbance. because the atmosphere of tunnels or underpasses is often a small place. The possibility of triggering possible security issues is somewhat greater than on other parts of route. As a result, it is vital to choose lighting settings that have an anti-glare function. because such lighting fixtures allow drivers to see well.
so before making a purchase. You'd be wise to inquire with your suppliers about the techniques they use or the precautions they take to minimize the glare produced by their led tunnel lights. This manner, you can choose the optimal solution and maximize your customers' satisfaction.
