Led Public lighting(CLASSIC) is rapidly occupying the artificial lighting market for a variety of commercial, manufacturing and residential applications. Advanced LED technology and versatility, as well as the superior economics and efficiency of LED public lighting, are the most common reasons for the increasing popularity of LEDs. However, many newcomers to LED public lighting find themselves confused about the terminology of LED common lighting performance, especially in terms of the "lumen" rating of LEDs.

The wattage rating used to describe incandescent bulbs is often confused with the brightness metrics of these bulbs, and in fact, the wattage is the level of charge consumed by the bulb. A bulb with a higher wattage rating is usually brighter than a lower wattage bulb, but the wattage is not a direct measure of bulb brightness. To do this, you need to refer to the lumen level of the light. Technically, "lumen" is the amount of light from a source that reaches a defined surface area that is a set distance from the source. If the light source produces more light and the defined surface area looks brighter, the light source will have a higher lumen level.

LED common lighting is rated on lumens rather than watts because they convert more input electrical energy into light than other types of artificial illumination, and the energy input is less dissipated into the heat. A 40 watt incandescent bulb and a 10 watt LED bulb may both generate 600 lumens, but an incandescent bulb requires 4 times the energy input of the LED bulb. As this example shows, you can use general rule of thumb to compare incandescent and LED bulbs, ie LED bulbs require only a quarter to one-sixth of the energy input (ie wattage) as an incandescent bulb to generate the same The amount of light in the bulb.

If you want to simply replace an existing incandescent bulb with an LED, and you want to continue thinking about watts, this rule of thumb will guide you to replace a 40-60 watt incandescent bulb with a 10 watt LED bulb, and an incandescent bulb from 75 watts to 100 watts. 15 watt LED. Designers or LED lighting technicians will be able to provide you with more targeted guidance to create lighting that will provide the best lumens for a particular part of your office or home.

In terms of public lighting(CLASSIC), people can make LED retrofits or use LED public lighting. Now people may be surprised by the advantages of using LED lights and why they now have gained a lot of reputation. However, as we delve deeper into and study some of the great benefits of LED retrofits, we even find that using LED lights at home can change a big change.

Our traditional lighting for public lighting takes up a considerable amount of energy, resulting in an increase in electricity bills. This can lead to cost increases and energy exhaustion. If we switch to LED public lighting, then we can expect to reduce electricity bills. This is because LED bulbs use very little power compared to incandescent bulbs or CFL bulbs. This is considered to be one of the main reasons you can help you understand how the transformation works.

Another advantage of using LED bulbs for public lighting is that they last for 75,000 hours. However, traditional incandescent bulbs and CFL bulbs do not last long and need to be replaced every few months. This leads to further indirect costs. Or, since LEDs can be used for many years, management costs are reduced and no one is concerned about maintenance costs.

In terms of the environment, LED bulbs are most common in traditional bulbs. The latter not only uses a lot of electricity, but also emits lead, carbon and heat that are harmful to the environment and increases the degree of pollution. In addition, LED lights are environmentally friendly because they do not emit any contaminants and heat. This helps us reduce our carbon footprint.

LED public lighting is very useful in industrial projects or industrial models. Choosing LED retrofits can help them reduce costs and reduce management costs, helping to reduce production costs. Therefore, there are many advantages to choosing LED retrofits.

As the leading region of domestic lighting technology, the Yangtze River Delta is supposed to be a sea of rivers and rivers. It is absolutely impossible to adopt the "standard" policy of closing the country in some places, and it is even more important to respect the science and respect the reality. It is under this guiding ideology that the region first applied Led Public lighting(CLASSIC) solutions in the tunnels on a large scale, and through the early use and improvement, its advantages of energy saving and long service life were greatly revealed, and the early failure and maintenance amount were greatly reduced. , which is also recognized by all parties.

As far as the results of serious experiments and demonstrations have been carried out, they must be implemented conscientiously in the renovation of lighting, and no personal fraud is allowed. From this aspect, it is recommended that the public lighting management agencies in the Yangtze River Delta must conduct expert reviews of products and technical solutions, and approve and supervise the competent authorities and users. If it is not scientific, fair and just, it will not reflect the scientific, leading and impartial nature of public lighting in the Yangtze River Delta. There are good experiences, conclusions and results. It is only like the chaos in some places in China that it can only damage the image of LED public lighting, which will definitely hinder the development of efficient and intelligent LED public lighting.

In summary, the application of LED products has matured in road lighting. Taking Los Angeles as an example, it can be clearly seen that after the replacement of LED street lights in the city, road lighting conditions are saving electricity, reducing carbon emissions and remote monitoring. Dimming, improved visibility and uniformity have been greatly improved and improved (Figure 7). According to relevant statistics, the city of Los Angeles has achieved an actual average energy saving of 62.9% (equipment energy saving plus regulation and energy saving); reduced CO2 emissions by 40,500 tons / year, and after two years of operation, in the light fade, failure rate, illumination, brightness, Uniformity, color temperature, power consumption, power factor, harmonic distortion, control capability, electrical connection, installation and maintenance of lamps have obvious advantages. And it is worth mentioning that according to Los Angeles police statistics, after using LED street lights, the crime rate dropped by 10.5%. Therefore, it can be said that we should be rigorous and speed up the action, and accelerate the development of LED road lighting has become the trend of the times.

First, public lighting(CLASSIC) and its systems have a natural platform for information perception and feedback in smart cities. City Light has a complete and independent power supply system. Due to its unbalanced use characteristics, the margin is sufficient, so there is no need to lay cables to meet the power needs of communication and information facilities.

Second, networked distribution is one of the biggest features of public lighting layout. With the increase of road network density, the network distribution characteristics will be more obvious and reasonable, and the dead angle will gradually disappear. The dead end network distribution of communication and information facilities is the basic condition for comprehensive information coverage of smart cities. Of all municipal facilities, only public lighting systems cannot achieve unwarranted network allocation. Therefore, it is a natural loading platform for smart city IoT devices.

Third, the height of the public lighting and the capacity of the interior cavity are sufficient to carry a sufficient number of communication and information devices under the requirements of the integrated design, which are becoming smaller and smaller. The public lighting structure has three basic components: the pole, the seat and the arm. In custom public lighting, there is usually a body with a unique structure. The large capacity of the lamp holder and the main body cannot be forgotten, that is to say, the lamp post and the lamp arm can also be loaded with communication and information devices by a reasonable design without affecting the aesthetic appearance of the lamp.

The last point is that the operation and maintenance system of the public lighting system is ready-made, perfect, professional, and provides a guarantee for the operation of the smart city.

In short, public lighting is a public product provided by the government and has good sharing conditions. Although its main function is to ensure road traffic safety and safety precautions, due to a wide range of public lighting, global coverage, system independence, independent systems, independent power drive functions and maintenance team professional, fault handling is timely, therefore, it is not A municipal facility that provides lighting, but a carrier of several functional systems in urban space. Therefore, the lack of public lighting in smart city systems is not a complete smart city.

In recent years, China's LED lighting market has continued to expand, and its manufacturing capacity and export volume have ranked first in the world. Especially in 2013, with the acceleration of the elimination of incandescent lamps, the penetration speed of LED lighting has obviously accelerated, and the emergence of the market has emerged. Commercial, industrial lighting and public lighting(CLASSIC) have become the key application areas. The industrial electricity consumption has always accounted for more than 70% of the electricity consumption in the whole society in China. The demand for electricity saving is strong, and the LED industrial lighting space is huge.

With the improvement of the domestic and international policy environment, the overall development of the LED industry has shown a rapid development trend, and the development environment is becoming more and more perfect. Internationally, countries have systematically deployed semiconductor lighting based on national strategies, and the policy environment has been increasingly optimized. For example, the incandescent lamp prohibition order, the demonstration project financial subsidy policy, and other methods, the research on high-efficiency LED lighting detection methods and the formulation of relevant standards preempt the standard discourse rights. Wait. At the end of last year, the EU had completely banned the sale of incandescent lamps.

From the domestic point of view, with the State Council arranging 2.2 billion yuan to support the promotion of energy-saving lamps and LED lights, the release of the roadmap for the elimination of incandescent lamps, and the bidding for the subsidies for the promotion of semiconductor lighting products, the relevant policies of China have gradually tilted toward the application side. In particular, in January this year, six ministries and commissions jointly promulgated the "Semiconductor Lighting Energy Conservation Industry Plan", which clarified the development goals, main tasks and key projects of China's semiconductor lighting industry during the "Twelfth Five-Year Plan" period, and promoted the health of China's semiconductor lighting industry. Order development.

What is an LED driver? Led Public lighting(CLASSIC) cannot work without a driver, and the LED driver is a power converter. The LED consists of a housing, a light source and a driver. The drive, the autonomy of the luminaire itself is very important, it not only makes the LED public lighting so simple, but also directly affects the life of the luminaire.

In general, LED drivers are especially important when the lamp is relatively reliable. The LED driver is actually a circuit structure that regulates current and voltage, just like our computer charger. In fact, very few household appliances can operate automatically within the range of charged inputs, most of which need to be modulated to the appropriate voltage range. The LED driver is mainly current modulation. To put it bluntly, it is the power used by the LED lamp bead, while the ordinary power supply is the difference between its constant current, so it is a constant current power supply.

With the rapid development of the LED public lighting market, the LED driver market is also growing. According to market research organizations, LED IC market revenue will reach nearly $4 billion from nearly $2.5 billion in 2010 to 2018, with an average compound annual growth rate of 17%. The agency also pointed out that LED public lighting needs LED IC, will become the main force of market growth, lighting, automotive headlights and other emerging applications of the LED market came into being, set off another wave of LED trade boom.

What we want to remind you is that the city is beginning to consider other ways of using public lighting(CLASSIC) poles. These rods are more confusing than poles, but offer the same advantages of height and versatility.

Once the community considers an intelligent lighting plan where some type of sensor regulates light, an internet connection is required. Sensors can then be used to collect and transmit video information from security cameras, build public Wi-Fi systems based on existing Internet needs, provide broadband Internet in vulnerable areas, monitor traffic and coordinate traffic signal times, collect weather or air pollution data, and even automatically Coordination of driving a car, commonly known as autonomous driving.

If your community can do better in any of these areas, and if you have or are looking to install some smart lighting, then exploring other possible uses of these polarities can be important.

Light pollution (generally unwanted light in the sky) and light intrusion (unwanted light that illuminates adjacent buildings) are also an increasingly important issue.

If light intrusion plagues residents, they will be complained. In the past 25 years or so, great progress has been made in providing highly oriented public lighting(CLASSIC) that does not spill into unwanted areas.

If you need to retrofit an old street light to solve the problem of light shining into the bedroom window, the cost of the directional shield is much lower than the street that replaces the entire fixture or fixture.

Some towns have so-called dark sky regulations that require public lighting to be highly commanded and do not spill into the sky. Manufacturers also occasionally rise through the production of night sky fixtures.

Operational and maintenance costs and considerations

Mercury vapor lamps are inefficient at using energy. Of course, the type of luminaire we use (we will say "the globe" at home) can dim the light produced by the bare lamp, resulting in inefficient energy.

Solar installations can now be used in towns and cities that want more sustainable, or to eliminate the ongoing cost of electricity public lighting.

However, in terms of operating costs, there are other considerations, including the frequency with which the bulb must be replaced, what happens when the car hits the utility pole, and the expected life of the entire luminaire.

If maintenance requires special equipment that is not available to your community or town, you must consider any costs of the necessary equipment.

The quality of LED driver power will directly affect the service life of Led Public lighting(CLASSIC), so how to do LED driver power is the primary task of LED power supply designers.

Nowadays, in order to save energy and save electricity, LED public lighting has been greatly promoted, but LED needs to be equipped with power supply, and its quality will directly affect the service life of LED. Therefore, how to make LED driver is the primary task of LED power supply designer. This article describes some of the issues with LED driver power and hopes to provide some help to engineers.

Speaking of LED drivers, it refers to digital drives and analog drives. Digital drive refers to digital circuit drive, including digital dimming control, RGB full color conversion and so on. Analog drive refers to analog circuit drive, including AC constant current switching power supply, DC constant current control circuit. The drive circuit is composed of electronic components, including semiconductor components, resistors, capacitors, inductors, and the like. These components have a lifetime that can cause failure or partial failure of the entire circuit. LEDs have a lifetime of 50,000-100,000 hours. It lasts for 50,000 hours and has a life span of nearly 6 years. The life of a switching power supply is difficult to reach six years. The warranty period for switching power supplies on the market is generally 2 to 3 years. The 6-year warranty power supply is military grade, and the price is 4-6 times that of the ordinary power supply. Lighting factories are difficult to accept. Therefore, the failure of LED public lighting is mainly the failure of the drive circuit.

We believe that with the development of new zoning and residential areas, public lighting should be required and wiring should be required to be buried underground. We are consistent with our theory that walking or cycling communities are highly desirable.

In existing residential areas, residents' preferences are often the most important factor. Some communities feel safe and semi-rural, and unless it is necessary for driver safety, public lighting(CLASSIC) will only annoy residents.

Even so, by using simple reflectors instead of well-designed public lighting plans, you can better highlight specific drops or other roadside hazards. In many places, residential public lighting has been added and the bulbs have only been replaced when residents complain.

Typically, you can pay for the installation through a special assessment, which is a voluntary tax on specific residents and/or business groups. The special assessment will take effect within the specified number of years and is usually paid monthly as part of the utility bill.

Of course, a special assessment that is paid monthly or annually “running with the property” means that if the home is sold, the next homeowner is also responsible. In some countries and situations, one-off special assessments are also legal.

For residential streets, the recommended interval between fixtures is typically every 400-600 feet, but it is more practical to consider local climate and tree coverage before making a decision. The color and reflectivity of the street surface is also important.

When the distance is not easily divisible by the recommended interval, decisions and therefore conflicts are also common. So be prepared to have some warm conversations with citizens.
