Heat Dissipation Is The Key to Public Lighting

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.

Problems Encountered by LED Street Lights Manufacturers in Demonstration Applications

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.

US Department of Energy Encourage Investment in Energy-saving Public Lighting

For many years, the U.S. Department of Energy has been advocating "green" energy-saving public lighting(CLASSICLEDLIGHT) technology to cope with the global climate situation and U.S. dependence on foreign oil. In 2013, US Secretary of Energy Ernest Moniz announced an investment of 10 million US dollars in development projects to explore and support energy-saving solid-state lighting. The resulting project investigated the performance and complexity of light-emitting diodes and their contemporary use in large-scale infrastructure.

The Director pointed out that although the use of LED technology in the private and public sectors has increased tenfold, the cost of LEDs has decreased by nearly 54% due to improvements in LED manufacturing technology. We are living in a "perfect storm", which makes it an ideal time to consider the widespread adoption of LED public lighting alternatives and the large-scale migration of our national infrastructure to this cleaner and more environmentally friendly lighting method.

The efficiency of modern light-emitting diode technology is about 7 times as high as that of old-fashioned traditional lighting, and its service life is as long as 25 times. Light-emitting diode lamps consume only 10% of the energy required by incandescent lamps, less than half of the most common compact fluorescent lamps (CFL) today. In the eyes of a government trying to promote sustainable infrastructure and reduce carbon emissions, LED public lighting is obvious for large-scale investment.

Over the past decade or so, the United States has invested heavily in the research and development of light-emitting diodes and has invested capital in the manufacture of light-emitting diode technologies in an effort to reduce costs. In May 2015, the U.S. Department of Energy awarded nine other research contracts for the development of LED and solid-state LED core technologies. Recently, the successful conversion of Portland and Detroit from high-pressure sodium lamps to new light-emitting diodes has been reported in detail, which continues to enhance the positive impact of light-emitting diode investment.

As more and more cities and municipal authorities invest in clean, low-cost and energy-saving lighting, the future of the United States does look bright.

Choosing The Right LED Street Lights Manufacturers Is Not Easy

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.

Which Points Should Be Paid Attention to When Installing Solar LED Street Light

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.

Public Lighting Is Inseparable from Our Life

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.
