With the acceleration of urbanization, LED street lights have already entered people's vision. Nowadays, LED street lights can be seen everywhere in the streets and alleys of big cities, which adorn the night sky of cities. However, it is still not fully utilized because of its own limitations. In order to ensure that LED street lights can play a more important role in our life, Led street lights Manufacturers(CLASSICLEDLIGHT) should solve the following problems in future research, production and application:

First, the appearance and structure of lights. The appearance of traditional street lights is basically the same, generally divided into two parts: light source and electrical appliance. However, due to the particularity of LED light source and different light distribution methods, the appearance of LED street lights can be described as a variety of patterns, many of which cannot meet the operation requirements, and even some enterprises apply indoor standards to outdoor street lights.

Second, there are problems in the connection between LED lights and light poles. At present, almost all LED street lights are fixed by screws, and few are fixed by hoop bolts. In this way, there are great hidden dangers for the safe operation of lights.

Third: the replaceable problem of light components. LED street light components generally include LED chips, power supplies (drivers) and light housings. The vulnerable parts are mainly power supply and chip. Generally speaking, the LED light chip cannot be replaced, and the power supply (driver) can be replaced. However, many products are not convenient enough to replace the power supply (driver) and the replacement is too time-consuming.

As we all know, the life of LED lights can reach 30,000-50,000 hours. If the LED chip cannot be replaced, it means replacing the whole light and causing waste.

Fourth: the life of power supply (driver). Power supply (driver) is a key component of LED lights. However, the quality of LED chips is generally guaranteed in the market at present, while the life of power supply (driver) is another matter. General manufacturers promise to guarantee 2 years is good. This is because the development of LED street lights has encountered a new bottleneck-the quality of power supply (driver) cannot be guaranteed, which restricts the development of LED street lights.

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.

Compared with traditional street lights manufacturers represented by high-pressure sodium lights, Led street lights Manufacturers(CLASSICLEDLIGHT) have many obvious and potential advantages.

(1) The high luminous efficiency and low energy consumption

Facts have proved that replacing 250W high-pressure sodium light street lights used on secondary roads with 100W LED street lights with scientific and reasonable light distribution can not only meet the average illuminance required by road lighting standards but also greatly improve the uniformity. However, the average illuminance of high-pressure sodium lights may be higher in some areas, but the uniformity is very poor. Thus, LED street lights have considerable energy-saving space.

(2) Long service life

The life of street light directly affects the maintenance cost of the whole road lighting. At present, the service life of high-pressure sodium lights is generally about 20,000 hours, the service life of high-pressure sodium lights for road lighting is only about 5,000 hours, and the service life of high-power LED is generally 50,000 to 70,000 hours.

(3) Good color rendering

Although the high-pressure sodium light has the highest luminous efficiency in traditional light sources, it's color rendering is the worst, and it's color rendering index Ra is only about 20. Such poor color rendering can only help people to detect the road conditions, and cannot help pedestrians to distinguish clearly. The color rendering index of LED can reach about 80, which is basically close to natural light. The color rendering of the LED is more realistic and can reflect the color of the object itself. The high color rendering of LED is undoubtedly helpful for drivers and pedestrians to identify targets and provide better traffic conditions under the same road brightness.

(4) Quick Start

Incandescent light lights up at one point, but the actual starting time is about 0.1~0.2 seconds. Gas discharge lights such as high-pressure sodium lights and metal halide lights need tens of seconds or even ten seconds from start-up to stable light output and can be started only after cooling for 3-6 minutes after being turned off. However, the start-up time of LED is only a few tens of sodium seconds (ns), and there is no waiting time for a restart. LED lights can normally work in continuous on/off state.

(5) Facilitate optical design

LED is small in size and can emit light directionally on the half-plane. It can be regarded as a point light source in light design, which is very suitable for optical design by using a lens or reflector to obtain ideal light distribution and achieve higher light efficiency.

(6) Strong plasticity and firm structure

The plastic shape of LED street lights is strong, which can reflect decorative and local cultural characteristics through shape design and add additional value of aesthetic feeling and city image.

(7) Low carbon and environmental protection, especially suitable for solar photovoltaic technology

Gas discharge lights such as high-pressure sodium lights contain harmful substances such as mercury, which will cause long-term serious pollution to the environment and water sources after the light source is discarded. LED chips and their packages can meet the requirements of the EU RoHS directive and are free of harmful substances such as mercury and lead. The LED can be recycled after being discarded and will not pollute the environment.

(8) Has a potential total cost advantage

At present, the unit price of LED street lights is more than 4 times higher than that of high-pressure sodium lights. A 250W LED street light is equivalent to a 400W high-pressure sodium light, but the former costs 6,000 to 8,000 yuan, while the latter costs only 1,500 yuan. However, as long as the characteristics of high luminous efficiency and long service life of LED street lights can be brought into full play, the difference in initial cost can be recovered by saving electricity and maintenance costs. With the gradual maturity of LED street light technology and the continuous reduction of initial cost, its potential advantages in total cost will emerge in a short time.

For the selection of Solar led street light(CLASSICLEDLIGHT), we must first understand the illumination coefficient, road width, street light height, and other information in this area, and select the light pole height to be suitable for the brightness of the light cap. If the height of the pole of a solar LED street light does not match the brightness of the light cap completely, if the pole is low but the brightness of the light cap is too high, then too bright light will stimulate people's vision and glare is too high; On the contrary, the brightness is too dark to let pedestrians see things clearly, which undoubtedly increases traffic safety.

The following points should be paid attention to when installing solar LED street light:

1. During the construction process, attention must be paid to the installation position and the depth and width of the foundation. Please be willing to choose the best size according to the height of the light pole. When making embedded parts, attention must be paid to the selection of the ground cage with reinforcing ribs.

2. The foundation construction must not use cheap materials in order to save money, because that will reduce the bearing capacity of the foundation.

3. The installation of the light pole must wait until the foundation is completely solidified before construction. If the concrete is not solidified enough, it is urgent to install it. That is wrong because the wind-proof level of the light pole will be greatly reduced, and some will be inclined after installation, which will greatly affect the overall wind-proof level of the light pole.

Solar energy is a typical independent photovoltaic power generation system. This is only one aspect of the problem. What is more serious is that it is also a seasonal load that increases with the decrease in solar radiation. From the above analysis, it can be seen that the annual winter solstice is the time when the amount of solar radiation is the smallest, that is, when the amount of power generated by the solar cell module is the smallest, the annual winter solstice is the shortest day and the longest night, and the road lighting takes the longest time.

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.

Now people can't live without lights. The world without lights at night is dark, so it is necessary to buy lights to illuminate. LED street lights occupy first place in the field of lights. How to choose a good Led street lights Manufacturers(CLASSICLEDLIGHT)?

1. It is not an easy problem for engineering merchants to choose a suitable LED street lights manufacturers. If it is a low-priced light, we must make more comparisons before making choices, otherwise, there may be mistakes in quality.

2. In addition to some brand agents, LED street lights manufacturers have their own brands, which gives customers who want to wholesale more market space for their own brands.

3. LED street lights manufacturers are not only for lighting, the basic lighting can meet all the traditional modern light sources. What we pay more attention to is whether it is green and environmentally friendly, and the life span is 60% longer than that of ordinary lights.

4. Everyone thinks that the higher the color temperature of LED street lights, the higher the luminous efficiency, and the brighter the room looks, but in fact, the lower the color temperature, the more comfortable the eyes look and the lower the relative power consumption.

5. If the LED street light is used improperly, the eyes will be dizzy, thus causing damage to the eyes.

We know that many local engineering companies have not carried out anti-theft installation due to construction, leading to the theft of batteries and panels of Solar led street light(CLASSICLEDLIGHT). This situation not only affects normal lighting but also causes unnecessary property losses. According to reports of engineering cases, batteries and panels are commonly stolen. Faced with this situation, how should we take anti-theft measures for solar LED street light?

At present, the development of solar LED street light is not perfect. Compared with traditional street light poles, its composition is messy, which brings great difficulties to daily maintenance. At present, there are many deficiencies in the management and service system construction of solar LED street light equipment, resulting in the late management and service of solar LED street light can not keep up with the speed of theft and damage after the installation.

In order to reduce the theft of solar LED street light, the following aspects can be strengthened:

1. The cost of solar LED street light is higher than that of the traditional street light pole, and the technology of anti-theft and stability is not sophisticated yet. It should be set up in a public place or a safer place in the city, not easily installed in suburban areas.

2. Pay attention to the safety monitoring of solar LED street light, and set up a monitoring system or a device alarm system in simply stolen places so as to learn the usage of solar LED street light in time and carry out useful management.

3. Select-control boxes and other materials of solar LED street light that meets the standards and quality standards and ensures that the device of the consolidating parts meets the requirements during the device process, so as to ensure the consolidation of the solar LED street light and also play an anti-theft role to a certain extent.
