Lux levels

Are solar street lights Bright Enough? What lux level do I need?

Light measurement for solar street lighting systems

There are two important indicators of the brightness of the solar street light, Lux and Lumens.
Lux and lumens are both units of measurement for brightness. They are used to tell us the amount of illumination output and the brightness of the light falling on a given surface.

Lumens equals light output.
Lux (represented as lx) stands for luminous flux per unit area.

Relationship between lumens and lux:One lux is equal to one lumen per square meter (lm/m2).
lumens-and-luxIn this post, we will explore the Lux standards of street lights and why they are important. If you want to learn about lumens you can check out this article:UNDERSTANDING WATTS AND LUMENS: HOW TO CHOOSE THE RIGHT BRIGHTNESS LIGHT FIXTURE FOR YOUR PROJECT

What is Lux and why is it important?

Lux is a measurement of the light flux falling on a surface. Lux is the international unit of photometry, a method for measuring light intensity. Lux is used to specify the brightness of light or illumination. It is a standard light measurement for all types of lighting, such as household lights, office lights, car headlights, or street lights.

Why Lux Level Make Sense than Lumen

Lumens measure the light output of a single light source. The calculation method for lumens measurement is to multiply the wattage of the light source by the rated lumens per watt of the light source.

Lux is the amount of light on a surface. This can be measured he brightness of light after it travels a certain distance.

In addition to luminance, Lux levels are the best way to measure the brightness of solar street lights. Illuminance measurement can be easily done with just an illuminance meter, while luminance measurement requires specialized equipment and is more difficult to implement.
Now, when you have a solar street light bulb that produces 1000 lumens, its brightness will be different if placed 10 meters away. Therefore, changing the position of the bulb will change the brightness under different Lux levels. Lumens measure the amount of light produced by the bulb; Lux measures the distance light propagates.

Different road solar street lights Lux levels

According to standards specified in some countries’ government documents, we provide the following recommendations as a reference:

Highway lighting Lux levels

Solar street light

First-class highways, second-class highways: minimum average illuminance maintenance value 20 lx (low standard) / 30 lx (high standard), uniformity minimum value of 0.4;

Third-class highways: minimum average illuminance maintenance value 15 lx (low standard) / 20 lx (high standard), uniformity of 0.4;
Fourth-class roads: average illuminance 10 lx (low standard) / 15 lx (high standard), uniformity of 0.3;

The above illuminance requirements apply only to asphalt roads, and the illuminance requirements for concrete roads can be correspondingly reduced, with a reduction of not more than 30%.

Highway lighting levels should be determined based on the lighting standards of urban roads connected to them, the highway traffic control system, and road partitioning facilities.

The above average illuminance has two standard values, high standard values should be used for the following cases:

  1. Connected to urban roads with high-grade lighting standards;
  2. Poor visibility conditions;
  3. Inadequate highway traffic control systems and road partitioning facilities.
    When connected to urban roads with low-grade lighting standards, good visibility, and adequate highway traffic control systems and road partitioning facilities, low-grade values should be used for highway lighting.

Urban road lighting Lux levels

Express roads and main roads: minimum average illuminance maintenance value 20 lx (low standard) / 30 lx (high standard), uniformity minimum value of 0.4;

Secondary roads: minimum average illuminance maintenance value 15 lx (low standard) / 20 lx (high standard), uniformity of 0.4;
Side roads: average illuminance 10 lx (low standard) / 15 lx (high standard), uniformity of 0.3;

The above illuminance requirements apply only to asphalt roads, and the illuminance requirements for concrete roads can be correspondingly reduced, with a reduction of not more than 30%;

City road lighting illuminance values should be determined based on the area where the project is located, road positioning, traffic flow, road partitioning facilities, environmental brightness conditions, and actual needs.

High standard values should be used for the following conditions:

  • Central cities and areas, or main roads leading to large public buildings and places in the city;
  • Central business districts or main arteries of the city;
  • Roads with higher environmental brightness;
  • Main roads for people entering and exiting areas such as schools, hospitals, and nursing homes;
  • Roads with inadequate road partitioning facilities, mixed traffic of motor vehicles, non-motor vehicles, and pedestrians.

Low standard values are recommended for the following conditions:

  • Roads near residential areas and recreational areas;
  • Areas with lower environmental brightness.

Rural road lighting Lux levels

Solar street light cases

Primary roads: minimum average illuminance maintenance value 10 lx (low standard) / 15 lx (high standard), uniformity minimum value of 0.3;

Side streets and lanes: minimum average illuminance maintenance value 5 lx (low standard) / 8 lx (high standard);

Public activity squares: minimum average illuminance maintenance value 10 lx (low standard) / 15 lx (high standard);

The above illuminance requirements apply only to asphalt roads, and the illuminance requirements for concrete roads can be correspondingly reduced, with a reduction of not more than 30%;

Rural road lighting illuminance values should be determined based on the area where the project is located, road positioning, traffic flow, road partitioning facilities, environmental brightness conditions, and actual needs.

High standard values should be used for the following conditions:

  • Roads with high traffic flow near towns;
  • Large rural roads with dense commercial activities;
  • Roads with higher environmental brightness;
  • Roads with inadequate road partitioning facilities, mixed traffic of motor vehicles, non-motor vehicles, and pedestrians

Low standard values are recommended for the following conditions:

  • Rural roads in remote areas;
  • Roads within villages where motor vehicles do not pass through;
  • Areas with lower environmental brightness.

Intersection area Lux levels for motor vehicles

  • Intersection of Grade 1 with Grade 1, Grade 2, Grade 3: minimum average illuminance maintenance value of 30 lx (low standard) / 50 lx (high standard), uniformity maintenance value of 0.4;
  • Intersection of Grade 2 with Grade 2, Grade 3: minimum average illuminance maintenance value of 20 lx (low standard) / 30 lx (high standard), uniformity of 0.4;
  • Intersection of Grade 3 with Grade 3: minimum average illuminance maintenance value of 15 lx (low standard) / 20 lx (high standard), uniformity of 0.4;

When the lighting standards at the intersecting roads are both low standard illuminance values, the intersection area should adopt the low standard value, otherwise, the high standard value should be used.

Pedestrian overpass lighting Lux standards

  • For pedestrian overpasses with high human flow in rural areas and low human flow in cities: average illuminance of 5lx on the bridge deck, average illuminance of >6lx on the stairway path;
  • For pedestrian overpasses with high human flow in cities: average illuminance of 10lx on the bridge deck, average illuminance of >12lx on the stairway path;
  • For semi-enclosed pedestrian overpasses: average illuminance of 30lx on the bridge deck, average illuminance of >36lx on the stairway path;

Solar LED Street Lights Application Analysis

When Greta Thunberg, a Swedish environmental teenager, chose to sail the Atlantic for two weeks before arriving in New York for the United Nations’ youth climate summit, Luxmanlight employees were actively promoting the use of Integrated Solar LED Street Lights around the world. Different views on the same event just represent our different ideas on environmental protection.

The all in one solar LED street light is the product of modern science and technology development. It directly uses solar energy for power supply, environment-friendly, and energy-saving. With the characteristics of once investment and long-term return, traditional street lamps and an LED street lamp is gradually replaced. The solar street light with an automatic lighting system is generally used for street lighting of urban and rural roads. The intelligent street lighting system can realize the intelligent monitoring and management of street lights and reduce the operation and maintenance cost of the system. Thanks to its stable performance, easy management and no need for electricity connection, it is becoming more and more popular. Solar LED street lamps are used in parks, communities, squares, and parking lots from remote rural areas to cities. According to our customer’s experience, now we summarize the main installation locations of solar street lamps.

 

Application location of solar LED street lamps

  1. Rural road lighting

The rural natural environment is harsher, not suitable for laying cable. Solar lamp installation is simple, long service life. Moreover, rural roads are narrow and small, and the requirements for LED light sources are not high, which is suitable for installing stand-alone solar LED street lights.

  1. Monitoring and lighting of farms, barns, doorways, and courtyards

House installation of solar street lights not only very convenient night lighting, but also can be equipped with a camera monitoring function. In the meantime, installation is simple, still can save a lot of electricity bills. Current standard configuration with light control, will according to illumination (brightness) automatically turn on-off the light, auto-off in the day, auto-on light at night, very simple and convenient.

  1. Homestay, resort, and hotel outdoor lighting

Lighting safety, environmental protection, and energy-saving are the pursuit of the concept of homestay and hotel, so the solar street lamp is the right choice.

  1. Mining area, remote power shortage place lighting

Mining areas are usually quite remote, so the cost of installing street lamps by cable is very high. Therefore, it is appropriate to choose a solar street lamp. Luxman solar LED street light works 12 hours a night and can support 5-7 rainy days. The road may still be rough, but it is no longer dark and safe to travel.

  1. Island lighting

There is no doubt that islands are short of electricity, especially the remote, smaller islands, which are 100% short of electricity. Diesel power doesn’t work 24/7 and there are always dark hours, but solar lighting will keep your nights dark no matter how windy or rainy.

  1. Monitoring and lighting of the home town villa

Many young people like to live in the city, where the house is only for old people and children or no one lives. Therefore, a kind of solar street light with a camera that can be illuminated and monitored is very suitable for use. like Luxman S3C Series solar street light with a camera for residential areas.

  1. The lighting of urban roads and secondary trunk road

Energy-saving and emission reduction can be achieved not only by using AC Powered LED lighting, but also by using more advanced solar-powered street lighting without electricity bill, which can be invested once and be effective for a long time.

  1. Square, parking lot, playground lighting

There’s a lot of traffic in public places, but it’s usually only in the early hours of the night. The intelligent solar street lamp can do induction mode(PIR), time control mode, and can also do induction + time control hybrid mode, so it can meet the lighting use in public places.

  1. Schools, hospitals and museums outdoor lighting

Environmental protection is everyone’s business. The low-carbon concept must be promoted from schools to hospitals, exhibitions, museums, and another outdoor lighting. Integrated solar street lamps not only meet the lighting needs but also have a prominent environmental protection demonstration effect.

  1. Park and green space lighting

In general, the lighting of parks and green Spaces does not require high illumination on the ground (compared with outdoor stadium lighting). Intelligent solar street lamps are the best choice for lighting in these public areas.

  1. Community road lighting

The lighting of community roads and garden roads in the community has changed from traditional lamps to LED lamps and then to solar street lamps, which is the trend of the times.

  1. Industrial zone, science, and technology park, road lighting

In industrial areas, science and technology parks or innovation incubators park, no matter traditional lighting or LED lighting which used for public electricity, it is not as cost-effective as solar street lamps after cost accounting.

13.Outdoor camping lighting

The installation of LED solar street lamps in some of the best places for camping not only solves the main problem of campers but also ensures their safety to some extent.

In the future, more than 70% of roads and lighting are expected to use solar street lamps, compared with less than 5% today. At present, the price of a solar street lamp is mainly set according to the level of parameter configuration, and the service life is closely related to the configuration. The solar street light manufacturer offers a five-year warranty, which is favored by many customers.

According to the solar street light market report, the global solar street lighting market was valued at approximately USD 4.25 billion in 2017 and is expected to generate revenue of around USD 18.31 billion by the end of 2024. The Solar Lighting Market is prompting demand growth both in the consumer and manufacturer.

Solar-Powered-Motion-Light-Manufacturer

So how to be the best solar street light factory in China?

First,own Years of Production and Manufacturing Experience

It is very important to have a stable supply chain system for the production of solar street lamps, because some key components of solar street lamps, such as batteries, solar cells, solar controllers, and so on, are decisive factors for product performance and lifetime. If the supply chain system is unstable, it will directly affect product quality & lifetime.

In addition, the solar street lamp is a small solar power generation system, which seems to be a simple product, but in fact, the assembly of a system product is not as simple as the assembly of product parts. In addition to good product components, a good solar power generation system should also pay attention to its system operation status, such as controller, the precision of procedure, battery protection function, a setting of light mode, and so on.

The control of processing technology is also very important. If you have many years of production and manufacturing experience, you will have a good running-in both from the product supply chain and product performance, and you can OEM and ODEM solar street light, which is based on years of production and manufacturing experience, and practical application and installation experience and data in the past few years, so as to produce more stable and more consistent products as market demand.

Second, good quality control ability

Any good products can not be separated from strict quality control; otherwise, the products manufactured will not be able to ensure that it is a qualified product. As a good all-in-one solar street light manufacturer, series of quality control should be carried out from the quality of incoming materials, the quality in the process of production and processing, and the quality of the shipment to ensure that each product is qualified from raw material to the customer. Hence, a top solar street light manufacturer must have a strict quality control system.

Third, responsible after-sales service

In LUXMAN, the sale of a product is only the beginning of sales. We will track the products sold from logistics to installation and during use. We have an ID bar code tracking system for all the products delivered. If there is a problem, we can trace the source material to installation quickly. We pay great attention to the customer’s experience about the use of our products, regularly understand customer feedback and final consumer feedback on the use of our products, and minimize customer investment in after-sales. Customers in the purchase of our products, without worries, are our goal and direction of efforts.

Fourth, leading technology

Now the solar street lamp products have developed, from the first generation split type and the second generation half-split type to the third generation one-in-one type.

The third-generation product of integrated solar street lamp, whether from product design, performance, product quality, product cost-effectiveness, has made a leap forward. At present, the third generation of integrated solar street lamp is much more intelligent. It can adjust and programmed the light mode, brightness, and so on through a remote control switch. Some intelligent products can be connected with APP, monitor the working parts of the product in real-time on the mobile phone, and know the working status of the product in time. What’s more, with proven technology, the CCTV camera is connected with the solar street light providing surveillance for 7*24hours.

A best solar street light manufacturer invests more in R&D because if he has good product technology, he will have a more competitive advantage in the market.

The above aspects are about what kind of manufacturer is good solar-led street light manufacturers, and one of them is that a good all-in-one solar street light manufacturer is very concerned about the user experience.

Solar Street Lights 5 Kinds Applications -LUXMAN LIGHT

As we know Solar Street light has the following benefits:

* Installation anywhere

* Maintenance-free

* No underground or overhead service

* No electricity bill

* Different styles available

* Mobile phone remote control

* Real-time 24 hours of surveillance and security function optional

 

From the above advantages of solar-powered street lights, it can have a wide application, so in what areas can all in one solar light be applied?

Solar-Street-Light-Applications

1st– Remote Areas

Such as rural roads, islands, military barracks, farms and so on, because these places are remote or inhabitants do not live centrally, so the laying of electric wiring is very difficult, the cost of laying wiring is not proportional to the utilization rate, so solar pole lights can be used in remote areas.

2nd – Construction Site

Because these are temporary places, so access to power or installation of lighting is inconvenient, LUXMAN once had a customer who bought LUXMAN all in one solar street lights is leased to large local builders.

3rd – Campus, Square

Generally, these places are very empty, have a better sunshine foundation, on the other hand, the flow of people in these areas will be more during 6pm-10pm, and later will be reduced a lot, solar streetlight sensing and timing control functions well meet this demand characteristics.

4th – Road and Street

This application is also the most important application, street light power consumption is usually relatively large, in some countries and regions, electricity is very expensive, if the solar street lamp can be used to replace ordinary street light or LED street light, then a huge cost will be saved.

5th Residential Areas

Solar street lamps have good mobility. Residents can install different places according to their needs, such as swimming pool, Party table, courtyard entrance, Parking lot, etc. In addition, the extension function of solar street lamps can also meet the needs of residents, such as camera monitoring function, USB charging, mobile phone APP operation function and so on, bring users a more convenient user experience.

Analysis On Street Light Electric Shock Caused By Heavy Rains

Every summer during the rainstorm season, news of casualties caused by street light electric shock accidents occurs. Most of the Electric Shock of Street Light caused by light electric leakage on rainy days. Due to the high temperature and humidity of street light facilities in summer, the cable insulation layer is easy to aging and breakdown, leading to electric leakage. In addition, thunderstorms Street light Leakage Accident occur frequently in summer, it forms water accumulation on roads, which immerses urban lighting facilities (such as cable wells, street light poles, etc.) in water and easily causes electric leakage accidents. The leakage of the street light pole may occur in the following ways.

led street lightstreet light

  • The poor quality construction causes leakage of lighting facilities.

Failure to comply with the standard construction or installation quality problems, such as screw damage to the insulation layer of street light cables during installation. In rainstorm days, when urban rainwater soaks live equipment, it will cause the connection equipment live. Leakage caused by rainwater immersion.

street light poles LUXMAN - LED Street Light Pole

  •   The aging and damage of the cable insulation layer in the lamp pole make the lamp pole live.

Some construction simply uses a tape winding method, the tape is easy to aging, it is likely to leak electricity.

  • The poor quality of lighting electrical appliances causes the lamp pole to be electrified.

In the design and construction of urban lighting engineering, strict checks should be made on the selection of lighting appliances, the selection of certified light sources, electrical appliances, lamps, and other products should be a priority.

  • Discharge of wiring terminals.

At present, most of the wiring connection modes are peeling and winding. This mode has high resistance, high current, short heating life of terminals, and will discharge when moisture or water is immersed.

  • The electricity of the lamp pole caused by man-made destruction.

It mainly refers to the cable which was stolen and damaged, cable fracture exposed to the lamp pole, and this easily leads to discharge accidents.

  • The harsh natural environment causes the lamp pole to be charged.

Because of thunderstorms, water overflowed the repair door holes, resulting in street light leakage. Or lightning strike on the lamp pole, because the lamp pole grounding is not good, resulting in burning electrical equipment so that the lamp pole around to be charged.

At present, more and more solar street lights used for roadway lighting, which completely solved the leakage accident. In addition to urban main roads, major facilities, buildings, large squares and other places such as secondary roads, residential roads, parking lots, parks, schools, hospitals, and so on, all of these places can consider the use of solar street lights. In addition, in some natural disaster-prone areas, such as flood areas and earthquake-prone areas, solar street lights are also a good choice because these disasters are easy to cause line damage and leakage.
