How to rationally deal with the problem of led highbay lighting pollution

At present, the LED display light pollution is divided into three categories, namely, whitepollution, led highbay lighting, artificial daylight, and light pollution. It was suggested that the LED’s light pollution problem, the combination of high brightness and glare LED blinking pattern ofadvertising to affect the safety of driving.
Recent research projects about light pollution that LED suppress melatonin levelshigher, it may affect human health. Such as: three months to mature vegetables, the use of LED Lights, led highbay lighting, even a 65% reduction in growth time, after eating may be harmful to humanimpact and may even harm.

It is reported that in foreign countries, the problem of led street light pollution has long been a cause for concern. The United States also established the International Dark skyAssociation, led highbay lighting, dedicated to the fight against light pollution. The government spent huge sums of money with all kinds of light whitewash Night in China, still exist, some usersexpressed dissatisfaction, the side is a high profile to promote energy saving and environmental protection cause, and power cuts to reach the common people and small and medium enterprises to implement energy saving row indicators, side luxurycosmetic bustling, neon lights, to spend the money who do not say, led highbay lighting, will only be allowedwhatever it wants while allowed to do anything than so. ”
Thus, while great efforts to develop light industry, light pollution should be the concern ofthe workers of the community and the street lighting, especially in the current investmentfrenzy in the LED high bay industry, there are many blind production, led highbay lighting, product design is unreasonable bring the light pollution problem should be taken seriously.

Analysis of the several classification led mood lamp

One class: made by the straw hat small power LED, LED energy-saving lamps, power RC step-down circuit. Straw hat LED continue to use the indicator LED package epoxy encapsulated, making the LED chip unable to shed heat, the light fades serious, a lot of white LED in the use of a period of time, the color temperature becomes higher, slowly into the bluish , led mood lamp, become dim. Factory efforts in the development of low-light decay straw hat LED, but the absence of changes to the package still did not change much, the light fades. These energy saving LED lighting products, is a transitional product, the price is low and of poor quality.

5050 SMD LED energy-saving lamps two categories: power LED made in 3528 or 5050 LED energy-saving lamps, led mood lamp, power is also commonly used resistive and capacitive step-down circuit, there are local manufacturers to adopt the constant current circuit, compared to the straw hat LED Post piece LED heat slightly better substrate for export with the aluminum plate, led mood lamp, can a local heat. However, due to the heat of the LED or ignored, in power SMD LED energy-saving lamps, no radiator, and as usual the use of plastic shell, the light fades is still serious. RC Buck low-end power grid voltage instability, the current shake, brightness shaken moderate price.

Three categories: made by high-power SMD LED, LED energy-saving lamps, power supplies commonly used constant current isolation circuit that is a constant current, such as 5W LED, usually 5-watt LED chips in series, with constant flow of 300mA of current source power supply, wide voltage power grid shaken when the current does not change, the luminous flux that is, to maintain a constant brightness, 5 SMD LED welding above the aluminum plate, aluminum plate and then separated from the radiator, the use of heat as quickly dispersed, to ensure that the temperature of the LED chip is less than the LED junction temperature allowed in order to ensure the true useful life of the LED energy-saving lamps. Such high price of LED lights, led mood lamp, good quality, LED energy-saving lamps to carry out the direction.

LED energy saving lamps, small size, high luminous efficiency, long life, low power consumption, the use of lunch, etc. was a vast consumer favorite. So far, LED energy saving lamps have walked into the thousands of families, but the LED lighting market is not very mature at this stage, various manufacturers specification different country specification of the LED high bay lighting has not been introduced, which also limits the LED lighting market well-being carried out.

The key dissipation of LED led road light technology: light, heat

Although the LED industry in recent years, rapid development, but it still lacks the authority of the technical standards, resulting in the industry as a whole mixed, the promotion of a wide range of very unfavorable. LED street light in a relatively high technical difficulty, led road light, lack of technical standards for the problems caused by very obvious. Many excellent technology of LED manufacturers and integrators, and do not know how to design a practical lights, applications department can not tell the specific requirements. For example, led road light, many manufacturers in order to solve the LED heat dissipation problem, design a “hollow type” shade. But poor on the street, so the shape of “shelter” function is not suitable for street lights.

Although government support, led road light, the LED street lamp market is the rapid development, but in order to truly get the long-term development of the LED street lamp market is still facing serious challenges. At present, the main problem facing addition to the high cost of LED high bay lamp products include: light, heat and power systems.
Light sources: one is to enhance the LED luminous efficiency, the other is to improve the arrangement of the light source. At present, a large part of LED lamp products on the market, LED light source is arranged in a lattice structure, this way of the biggest advantages is to help to solve the heat problem, but due to lateral irradiation distance of this structure is not enough, the light distribution larger, resulting in concentrated light distribution can not be achieved reflective cup, you need to use the second lens to achieve independence with light, which are higher for the selection of the secondary lens, led road light, secondary lenses of different materials there are some problems affecting product the results. If handled properly, the lens will also affect the lighting effects and clarity of the road.
Power: Unlike traditional lighting products can be directly connected to AC power, the LED is a low-voltage driven devices, led road light, and requires constant current drive, which requires re-design the power system of LED lights. LED power costs account for about 10% -20% of the overall product cost, power system, but off will largely affect the life of the product.

led street lights china new generation

In 1879, Edison invented incandescent lamps, which changes the history of People. Then halogen lamps, fluorescent lamps, CFLs, HID Lamps, now led street lights china new generation.

In 1962, GE invented the first Red LED, but it was only 0.1lm/w. In 70’s, Green, Yellow, Orange LEDs were invented, the lumen is up to 1 lm/w. In 80’s, new material GaAlAs was invented, then reach 10lm/w. In 1993, the led industry went into a new generation–LED Lamps for signal application.

Now, as the LED could start in low voltage, it’s suitable to use LED to replace the HID lamps in Public lighting application, especially none-people public zones, such as LED Street Lights China. Also, the CRI of HID lamps are not good, and CRI of LED Street Lights could be higher than 80, it’s very important for the traffic safety.

In the past times, Street Lights are regarded as the most important lighting applications, now, the power cost in Western countries are higher and higher, the governments are thinking over how to balance the safety and energy saving, then the Induction street lights were invented. They are installed with IR sensors, whenever the cars or people pass by, the lumen output would be 100%, after they gone, it would be reduced to 30%-50%. But the HID lamps are very difficult to be dimmable, on the other hand, LED high bay could be dimmable and start very quickly. After we slove the problem of led street lights china heat sink, the lifespan and light loss could be better, then the LED Street Lights could be a new generation of Lightings.

outdoor led spotlights–to do the leader of the green lighting

The Gaoyou for a small town in the northern Jiangsu area, but to enjoy the world-famous”lighting of the town, the good name of the street light manufacturing base, outdoor led spot lights, more than 600 of the town of existing road lighting manufacturers, and every four LED street light haveaproduced Gaoyou. The country as long as would like to purchase streetlights, must come Gaoyou “learn”!

1, the advantages of industrial clusters reflects: more than a dozen years ago, Gaoyouthere is the tradition of street lamps in recent years, Gaoyou enterprise specialized division of labor is getting smaller, specialized production, outdoor led spotlights, social coordination,production and business model replaces the previous large production business model,step by step from the rough to the brand, patented, high-tech industries,Technological innovation has brought the perfect effectiveness: the industrial upgrading can not be separated from technological innovation, the Gaoyou lightingcompanies have years research and development of solar road lights, solar garden LED high bay lights, solar lawn light, wind and solar lamps, etc. Our products are exported to Europe, the United States and Africa dozens of countries, thanks to technological innovation;

3, focus on quality to win the good reputation: because the Gaoyou people focus onquality, reputation, outdoor led spotlights, and foreign businessmen to come again and again from the product is sold to all over the world, even though the the Gaoyou street awareness is already high, but the the Gaoyou people still pay attention to the publicity, outdoor led spotlights, is now officialgradually improve the website Chinese street light network, with more than 40,000 member units in product introductions, the increasingly obvious role to expand its influence.

Analysis the difference of resolve solar powered led street light

Solar street lights and street lights, in addition to rather special in the design, construction and other requirements, the maintenance of the solar street lightingparticularly different like LED high bay, the following solar cell, for example:
To check the azimuth of solar powered led street light cell in the normal maintenance; whether the leaves and other debris blocking the absorption of ultraviolet light; whether in the shaded area;the surface of the battery cracked or damaged; monomer whether there are cracks, the connection is flat all The scope of the inspection. However, solar powered led street light the battery is the most difficult to maintain, solar batteries and other equipment is usually installed in the light pole base, because the relatively large size of solar batteries, additional light pole basemuch electrical door to facilitate the replacement of repair, only to increase light polebase, the volume of work completed and then re-install up to the normal life of our scientific and technological level of solar batteries is now three years, during this timehave to constantly check the battery charge and discharge at any time to check theelectrode or wiring there are poor contact. This is a project very big project by LED lights.

Once upon a time, in a small time, solar powered led street light there will always be asked by the elders dream is togrow up want to do, and we will say a few of their own career, and some want to bepolice, and some want to be scientists, and even somewant to be an alien. As years later, we again asked this question a lot of people into thinking, because of a childhood dream has been forgotten. Dream, this is indeed a question worth considering. (Ofinspirational articles) Why do some people as time goes by, more and more ordinary,time is merciless, solar powered led street light or cruel competition in the society, or the brutal competition … who isslowly strangling our dreams? Who is slowly stealing our dreams? May be ruthless time,may get good luck, there may be, we have lost their dreams. However, according totheir observed that many people are called “accustomed” mode gradually toward themediocre, or even fallen.

The only bright spot of the LED marine lighting Fair

Reported that the LED Lights are becoming the only bright spot in the 16th Guangzhou International Lighting Fair Pazhou concluded LED exhibitors. LED products technically have significantly improved varieties covering all fields of residential, led marine lighting, commercial, public, but mostly in commercial and public market force, and home applications, many enterprises have come up with effective solutions.

Products: Household LED street light sources are available
In the home field of the various types of lamps, chandeliers, lamps, spotlights, downlights, led marine lighting, fluorescent, and even crystal light source and the reading light source, LED products are everything, and has covered all household lighting.

Technology: LED technology breakthrough
LED concept can have a longer life, anti-vibration performance is very good, with good in the car, LED low voltage, used under the water is safe, LED energy saving, less demanding but to control the apparent color index used in long-term lighting occasions, can do the job. However, the LED is not without its drawbacks, the light fades too large, low color rendering index and color tolerance has been fatal to household lamps.
Rating: market acceptance needs to be improved
A lot of LED light-emitting principle is not suitable for made desk lamp, LED Street light more blue component, is not conducive to the vision. Luminous flux less than years of product appears in the LED lamps are a common problem, “low light, there is a problem is the color, led marine lighting, look at something below the LED lamp color distortion. The same time, shinesmall part, called light-shaped distribution inappropriate. addition, its bright luminous point, a direct look at it, will feel very dazzling “, experts said, the LED lamp is not yet a national standard, therefore, in addition to individual particularly good quality products, and can not play the role of eye protection. There is heat, the light fades quickly lead to a sharp reduction in product life, has been the industry criticized. According to the LED light source of some of the short board, the industry that are not suitable for LED lighting in the reading room, library and gymnasium, and other places.
More terrible is that the strength of the manufacturers are the main focus of the light source and the chip part, the whole lamp involving superficial. “A lot of LED manufacturers are not complete lighting manufacturers, led marine lighting, they have to use their own chips, or have to buy the cheapest chip shallow processing.” Obviously the whole light of the LED structure is still in the brewing of a Yun. Lighting is not a light bulb, but a combination of optical design, systems engineering, and want a quick popularity of the almost impossible.

Nanjing region is to promote the Promise solar led street light circuit

8m-10m high street lamp on 150W can replace the 250W sodium LED high bay lamp (System Power280W), 30m pole lamp, solar led street light circuit, 250W can replace the 400W sodium lamp (System Power450W), on-site visual effects better than a sodium lamp, which lightsNanjing gradually.Pioneered the use of this lighting is Pukou District jiangpu Street and Bridge Town.

We have recently seen in Bridge Town, the town’s construction workers are Longbridge Road, West Bay, West Chichiawan on the road to install new street lighting. Accordingto the charge of construction, solar led street light circuit, a few blocks originally are 300W traditional lights, put onthe new Promise street lights, 100 lights, annual savings of about 40,000 kwh of electricity. In Bridge Town before install energy-efficient lighting, the Pukou jiangpustreet has installed eight main road of the Wende, St. Road, Riverside Road area high-frequency electrodeless discharge lamp.
According to reports, this high-frequency electrodeless discharge lamp full name of thehigh-frequency plasma electrodeless discharge both electromagnetic induction principleof combining a new type of light source, solar led street light circuit, is the latest application technology of the 21st century “green light”. The bulb has no filament and the electrode, it does not exist to limit the inevitable component of the light source life, a life of up to 60,000 hours. It is reported that the street lights Promise has received national patents, has formed a series of large-scale production, all indicators have reached international level of similar products, solar led street light circuit, the price is about one-third of the imported products. Jiangsu ProvincialAssociation of Lighting the opinion of the Secretary-General attaches great importance to energy saving, green background, it is necessary to promote high frequencyelectrodeless discharge LED lamps.

Too high maintenance costs led to solar led street lamp forced to dismantle

It is reported that Shanghai Hongqiao transportation hub, a kilometers of trunk roads is actually a dark, brought great inconvenience to the people to travel at night. According to the people around here is the original street, and later demolished all. However, solar led street lamp and Eneltec LED high bay, the area of the establishment of diplomatic relations Committee, said the demolition of street lights to the laying of a new batch of street lights, the project is expected to start after the Spring Festival next year. At present, the entire route in addition to some of the light side due to the airfield lighting slightly, almost completely dark without led street light, passing vehicles and pedestrians had to carefully.

This road is a trunk road of the Hongqiao Integrated Transport Hub, opened to traffic on March 16 last year, solar led street lamp, the North Alliance Rainbow Road from south welcome all the way to a total length of more than 1600 m. However, the original road street, all street lights, long ago, not long ago was all dismantled. As the street lights were originally installed as a temporary street lights energy efficient street light pilot, coupled with high maintenance costs, has not been included in the range of conservation of the City street by the side of construction to bear these costs, so the removal of this group of LED street lights, it is The next formal street lights do laying.
It is understood that the construction side of the section has been submitted to the city street lights street lights laying applications, solar led street lamp, as long as the funding is in place, and then through a series of site survey, engineering sorting process can commence.
