When people have the need to travel at night, there is public lighting(CLASSICLEDLIGHT). Modern public lighting began with the emergence of incandescent light. Public lighting develops with the development of the times, the progress of science and technology and the continuous improvement of people's living standards. From people only require lighting the road surface to detect the situation of the road, to help people identify whether the road is a pedestrian or an obstacle, to help motor vehicle and non-motor vehicle drivers identify the characteristics of pedestrians, etc.

The fundamental purpose of public lighting is to provide drivers and pedestrians with good visual conditions and guide them to travel, so as to improve traffic efficiency, reduce traffic accidents and crimes at night, and at the same time help pedestrians to see clearly the surrounding environment and identify directions. With the development of social economy and the continuous improvement of people's living standards, more and more people go to outdoor recreation, shopping, sightseeing, and other activities at night. Good public lighting also plays a role in enriching life, prospering economy and enhancing the image of the city.

According to the view of public lighting, roads can be divided into four categories: special roads for automobiles, general streets, commercial streets, and sidewalks. Generally speaking, public lighting refers to special public lighting for automobiles. Among many purposes of public lighting, providing safe and comfortable visual conditions for motor vehicle drivers is the first.

The public lighting source was a street light at the earliest, and then came high-pressure mercury light, high-pressure sodium (HPS) light, metal halide light, high-efficiency energy-saving light, electrodeless light, LED light, etc. Among the more mature street light sources, HPS lights have the highest luminous efficiency, generally reaching 100~120lm/W, and high-pressure sodium lights account for more than 60% of the total public lighting market in China (with about 15 million lights). In some communities and rural roads, CFL is the main lighting source, accounting for about 20% of the public lighting market. Traditional incandescent lamps and high-pressure mercury lamps are being phased out.

First of all, for public lighting(CLASSICLEDLIGHT), heat dissipation is the key. Because the heat is not effectively conducted out, it will affect the service life of lamps and even cause a fire. At present, other industrial and mining lamps in the LED market adopt centralized heat dissipation, which results in poor lamp performance and reliability.

Secondly, for the factories, warehouses, workshops and other places where public lighting is applicable, insufficient lighting is easy to cause accidents. Through secondary light distribution design, public lighting can concentrate limited light on effective working faces. The three-light distribution modes can not only meet different lighting requirements but also ensure sufficient lighting in factories, warehouses, workshops, and other lighting places. More can enhance the uniformity of lighting, improve the utilization rate of the ground, save energy; It can also reduce light pollution and light intrusion, making lighting more comfortable.

Public lighting differs from traditional light sources in the following points:

1. The traditional lighting source has always failed to break through the energy consumption caused by electrodes and filaments due to its own technical defects, thus affecting the service life of the light source; However, because there is no filament or electrode in the bulb for public lighting, the life of the lamp only depends on electronic components, and the general life can reach 60,000-100,000 hours, thus realizing a long life.

2. Public lighting has remarkable energy-saving performance, saving 80% energy than ordinary incandescent lamps, 60% energy than metal halide lamps, and 20% energy than ordinary energy-saving lamps. 85W public lighting replaces 150W metal halide lamp (high-pressure sodium lamp). Under the same visual condition, comprehensive energy saving is more than 60%. Installing the same number of lamps and using public lighting can reduce the current of the output circuit by more than 4 times, and the capacity of the transformer is also greatly reduced.

3. Since the working frequency is as high as 2.65MHZ, there is no stroboscopic light at all, which will not cause eye fatigue compared with traditional light sources.

The lighting effect displayed by the public lighting(CLASSICLEDLIGHT) project of the park landscape can make the garden more elegant at night and convey the more beautiful artistic conception of the garden at night, which can be called the secondary life of the landscape. So, what should public lighting projects pay attention to when designing green space and trees in parks and squares?

How to use the art of light and light to create perfect public lighting is worth every designer to think deeply.

The night lighting design of the park shall meet the following requirements:

1. The illuminance level of the park should be determined and the appropriate lighting design method should be selected according to the function type of the park, the surrounding landscape environment, the theme style and the use of lighting lamps at night.

2. The influence of overflow and astigmatism on passers-by, surrounding environment and garden ecology should be avoided.

3. The illuminance standard value of the public activity area of the park shall conform to the provisions of Table 1.1.

Parks and squares are important places for people to live and relax. The public lighting of green space and trees should be people-oriented. Glare and light pollution to the environment should be avoided from the perspective of people's viewing, so as to create a warm and bright atmosphere for the promotion of citizens' nightlife.

The public lighting(CLASSICLEDLIGHT) has gradually entered our lives, and now our lives are beginning to be inseparable from public lighting.

The luminaire is a combination of the light source, power supply, lampshade, and other accessories. It is also used to control the light source and light projection, and at the same time, it can protect the light source and improve illumination efficiency.

The conventional public lighting fixture is mainly composed of a lamp housing, a light source cavity, an electric appliance room and the like. Because it has enough shell space and sealed and installed heat of activated carbon and foam silicone rubber, it ensures the working conditions of the light source.

Conventional street lighting public lighting can be made into any shape as long as this protective condition is guaranteed. The design of conventional public lighting fixtures in China is brilliant, showing the scene of daytime viewing and nighttime viewing.

The introduction of the semiconductor LED street lamps, the long life uniqueness of the light source, the superiority of easy and reasonable light distribution, the variability of color temperature, the advantage of high color rendering index, the low-voltage, current source power supply has the development trend of high efficiency and energy saving.

The public lighting(CLASSICLEDLIGHT) is an indispensable part of the modern landscape. It not only has its own high ornamental value but also emphasizes the coordination and unification of the landscape of public lighting and the history and culture of the scenic spot and the surrounding environment. Landscape lights use different shapes, different colors and brightness to create landscapes. For example, the red-light lantern-shaped street lamp brings a festive atmosphere to the square, and the green coconut tree lamp sets a tropical style on the edge of the pool. Landscape lights are suitable for landscapes such as squares, residential areas, and public green spaces. In use, be careful not to overdo it, so as not to overwhelm the audience, making the landscape look messy and flashy. Landscape lights also have certain disadvantages, such as not being environmentally friendly.

Trails and garden lights are actually a combination of two types of lights. The garden lights pay attention to the landscape, and the walk lights focus on the functionality. The two can be separated into their own systems, but after considering them, they are still combined. Public lighting for the trail.

The public lighting of the trail should pay attention to the following issues in the design:

1. The public lighting of the trail mostly exists in the form of diffused light. The difference between diffused light and direct light is that it does not produce excessive shadows, which makes the color appear softer when it becomes brighter and darker. However, an important problem that needs to be solved in the form of diffused light in the public light of the walk is that the surface temperature of the illuminator is too high. In view of the popular street garden lights on the market, few products can solve such problems.

2. Calculation of elevation angle and shoulder distance. The calculation of the elevation angle and the shoulder distance can achieve a good balance between the function and the landscape function. For example, if the design of the elevation angle takes into account the corresponding landscape design, then the role of the landscape can be better reflected. Meet people's needs.

The low-level luminaires first need to pay attention to the innovation of design concepts, followed by the humanization and diversity of functions. I saw a low-level lamp in Japan. This luminaire not only plays the role of lighting and beautification but also plays a warning role. It tells passers-by that the front has a large curvature and many people in and out. Please be careful with drivers and road walkers. In order to achieve the versatility of the low-level lights and the integration of landscape lighting, it is necessary to introduce the idea of composite design and coordinate the function lighting and landscape lighting as much as possible.

Another peak of power consumption is coming, and energy conservation naturally becomes a topic that cannot be avoided. How to save energy? Choosing energy-efficient lighting products is obviously an important means.

Don't underestimate this small public lighting(CLASSICLEDLIGHT). According to the data, at present, China's lighting power accounts for about 13% of the total electricity consumption of the whole society. If all the incandescent lamps are replaced with high-efficiency lighting products, the annual electricity saving will be 48 billion kWh. If the whole society realizes the replacement of LED lighting products, it can save about 350 billion kWh per year, which is equivalent to the power generation of four Three Gorges hydropower stations. If you change road lighting to solar street lighting, it is more energy-efficient and environmentally friendly.

"To change a light bulb and change the way we think, we can change the whole world." UN Secretary-General Ban Ki-moon said. A lamp may be insignificant, but the energy gathered can not be ignored. Frugal and healthy, low-carbon life, let's start from now, start from each of us.

When installing public lighting, many friends did not know that the voltage of the battery was 17.5v and the voltage of the battery was 12v. We know that the solar panels are composed of series-connected cells. The voltage of each cell is 0.5v. The 36 cells are 18v. It is generally lossy. The voltage rating is 17.5v, and the voltage rating of the battery is 12V. However, it is about 13v after a full charge. When the battery voltage is lower than 11.6v, it needs to be charged. The battery itself has discharge protection. We know that high voltage can only charge low voltage, and there is a pressure difference before it can be charged. Therefore, the voltage of the panel can charge the battery at around 18v.

In addition, when the system of solar street light is 24v, the solar panel is parallel with two pieces of the same power to charge the 24v battery. The other small series needs to be explained that the total power of the battery board is superimposed, the same power. The series voltage of the battery is doubled and the series current is doubled.

Many companies are optimistic about the development of Led Public lighting(CLASSICLEDLIGHT), especially the obvious energy-saving advantages of semiconductor outdoor lighting. In the past two years, many companies that have been rushing to the top, under the characteristics of semiconductor road lighting production, have simulated, counterfeit, and made a variety of "snakeheads" in the shape of today's conventional lighting street lamps. At one time, "a hundred schools of thought contend, flowers bloom." The products have been introduced to the market. After two years of testing on the road, most of the products have different levels of problems.

1. Due to the lack of understanding of the requirements of LED public lighting working conditions, the light attenuation is severe and even deadlights.

2. Insufficient perception of road lighting requirements, scientific point light source optical light distribution difficulties and neglect of the importance of color temperature in road lighting, easy to cause glare, zebra effect and in the environment of serious air pollution, rain and foggy weather, The phenomenon that the light is not bright enough on the ground.

3. Insufficient awareness of the working conditions of the LED and the technicality of the power supply, resulting in endless product failures on the power supply.

4. The application concept of today's LED public lighting practical road is unclear. Blind and high-power gas discharge lamps are “comparable” to produce super-high-power LED public lighting regardless of cost, which makes it difficult to promote unrealistic and expensive street lamp products.

5. The requirements for road lighting are vague, and the actual use and maintenance are not considered, resulting in the direct use of the owner's boycott.

With the increasing functional requirements for public lighting(CLASSICLEDLIGHT), the development of public lighting intelligence is changing with each passing day. The technical core of luminaire intelligentization is realized by intelligent control system on the one hand; on the other hand, the quality control and technical innovation of the light source can ensure the realization of relevant intelligent functions under the condition that the volume and quality of the light source are unchanged.

The intelligentization of public lighting can save resources and create a comfortable atmosphere with a sense of three-dimensionality and layering, which is conducive to people's physical and mental health. With the further demand for spiritual and material civilization, intelligent public lighting products will become the darling of the market and will be widely used everywhere.

In terms of channels, the main procurement of LED public lighting products is still municipal engineering in various places. Compared with other lighting product sales channels, public lighting channels are more specific, mostly invisible channels. This method plays a big role in the sales, brand promotion and promotion of public lighting enterprise products. It is understood that the government procurement model does not include the government's daily demand for fixed asset investment construction procurement projects into the engineering business category, but only the special procurement of LED public lighting products.

Public lighting companies also need to meet a number of qualification requirements to become a government procurement lighting supplier. The inspection of the qualifications of the municipal management department is mainly reflected in its own business philosophy, service awareness, and operation process. The quality information can be obtained through the analysis of the quality of its products and the investigation of the completed projects. From the price-oriented in the early years, the market is raging to the current strict quality control issues, the market is rational and cautious, which is important for the future direction of public lighting.

1. The current single Led Public lighting(CLASSICLEDLIGHT) power is low. In order to obtain high power, multiple parallel connections are also required.

2. Low color rendering. The color displayed under the illumination of the LED public lighting is not true of the incandescent lamp, which is to be analyzed from the spectral distribution, which is a technical problem.

3. Spots. Due to the defects in the manufacturing process of the white LED public lighting and the matching error with the reflective cup or the lens, the "yellow circle" problem is easily caused.

4. LED public lighting uniformity problem. If the secondary optical design is not carried out, and the illumination of the LED is relatively concentrated, it is necessary to carry out the secondary optical design, so that the light intensity distribution map can be made into a bat shape.

5. The current light fade problem of LED public lighting. And compared to low-power LEDs, the light decay of such high-power LED public lighting is much better now. However, low-power LED heat dissipation is small. Moreover, the high-power LED is a problem that there is no way to solve the problem of heat dissipation, and the brightness will be significantly reduced after the heat is generated, so the power cannot be made large.
