Developers to withdraw after the led street light manufacturer unattended

When developers put up street lights to save money out of their pocket, and now therepair and maintenance of unattended, 10 street lights became unmanned pipedecorations. Recently, led street light manufacturer, Miss Chang called for: an early Qin-mail on the road 10 street lights to light up!
Miss Chang introduced sets and drive from the highway, arrived at the Economic Development Zone and the high sand garden area, you can see the east-west trendingQin postal routes, erected during which a street lamp.

However, at night the road as the boundary, the western part of the bits and pieces of street lights Qin postal routesaccording to very clear, about 300 meters of the eastern section of the Qin postal routesintersect is dark. Although the sections of the road on both sides of each of the fivestreet lights, but throughout the year does not shine.
This section is the only way to the highway from the Qin postal routes, the traffic is heavy.During the Spring Festival, the traffic management department in order to solve thedifficulties of motor vehicles to turn left, came to this show Kang Road changed from two lanes to three lanes, the lane becomes very narrow, the edge of the motor vehicle mixedwith non-motor vehicles. Driving at night from the bright lights of Shanghai South Highway, led street light manufacturer also make LED high bay export, turn left to the Qin postal routes, suddenly into a dark area, the driver is a severe test.
To this end, Miss Zhang told the Economic Development Zone, wrote to reflect the situation last year. The near side of the road side of the street lamps light up, but did not last long, after the lamp is not bright.
This under the management committee responsible for municipal administration at theSpeaking of the 10 street lights are also very tangled. According to him, led street light manufacturer, the street lightsshould generally be managed by the electricity sector. But around the beginning of thereal estate development, real estate agency in order to save money, around theresidential quarters of the self-designed built street lamps. Today, LED Lighting Products electricity, repairs and maintenance has become a little overhead.

led chandelier light bulbs of low-carbon as a semiconductor lighting

September 27, television and telephone meeting of the national energy saving. The meeting proposed that China should focus on optimizing the industrial structure,promote energy conservation, led chandelier light bulbs, and develop strategic emerging industries, speed upeliminating backward production capacity, vigorously develop the circular economy.

Relevant statistics show that China’s electricity for lighting consume 12% of the totalsocial consumption of electricity. With the energy saving of the current economic development trend, led chandelier light bulbs, the semiconductor light reveals its essential strategic position. Inaccordance with the National Development and Reform Commission announced that China has eliminated incandescent route map (draft) “, 2016, China will complete phase-out of use for general lighting incandescent lamp, an estimated annual saving of48 billion kwh.
LED street light-emitting diode, is a solid light-emitting devices. It is a solid semiconductor chip as luminescent materials, through the carrier occurred in the semiconductorcompound to release excess energy photon emission directly issue the red, yellow, led chandelier light bulbs, blue, green, blue, orange, purple, white light. Semiconductor lighting fixtures using LED as light source manufactured to meet the daily lighting needs.
Compared with the traditional light source, LED Replacement Lamps has the incomparable advantage of the traditional light, almost a combination of the advantages of traditional light sources forapplications in a variety of traditional light sources. With low heat (incandescent lamp 1/8, fluorescent 1/2), less power consumption, long life (up to tens of thousands of hours of 3-10 times higher) than the traditional light, color, fast response, flash frequency, not to hurt the eyes, small package can be flat, slim and light products advantages.
Followed by Shandong Shan-Thai Group to develop the country the policy of the New Energy and Industrial R & D and production of LED Lighting Products, and its level oftechnology has matured and reached the international advanced level, led chandelier light bulbs, and developed the production of light forest license “LED lights, landscape lights , garden lights, lawn,and other products have been rated internationally renowned brands, and received a number of national, provincial and municipal awards. As in recent years, great importance to the efforts and support efforts to increase the semiconductor lighting industry, LED energy saving lamp industry will usher in a broader sky!

Phosphor price to soar along with price increases of energy-saving led downlights price

This year’s state financial subsidies to the energy-saving lamps are hot sales. Somecareful people, the price of energy-saving lamps by LED downlight this year than in previous years has been rising. It is reported that since the beginning of this year, led downlights price, as the production of oneof the most important raw material of the energy-saving lamps trichromatic phosphor, the price between a few months, rose to 300,000 yuan per ton from the present 70million. The impact of rising costs, some big brand energy saving lighting products has begun to raise prices. But industry insiders believe that the past few years the energy-saving lamps in Wuxi and the effects have always been leading in the province, even ifthe price increase will not affect its promotion in the city.

Financial subsidies to energy-saving lamps by LED tunnel this year rose
October 11, the local forum, several users post, said state financial subsidies to theenergy-saving lamps price this year than last year, up. Not only the unit price more expensive than in previous years, led downlights price, and the number of restriction from 20 down to 10.
It is understood that last year the city promoting the sale of financial subsidies forenergy-saving lamps each cheapest for $ 3.95, the most expensive 19.5 yuan. This year, the cheapest of each of 4.2 yuan, the most expensive 25 yuan. City financial subsidies to promote efficient lighting Office official explained, this is mainly becausethe energy-saving lamp power is not the same as last year, last year’s cheapest lamppower is 5 watts, this year is 7 watts, because from the actual sales 7 watts or morepower and more popular. The official, however, admitted that this year, as one of themain raw material for energy-saving lamps trichromatic phosphor price does soaring, but the launch of the financial subsidies the price of energy-saving lamps and nosignificant rise, led downlights price, especially residential customers to enjoy the financial subsidy of the half-price, or is minimal.
However, there is news that the well-known European lighting manufacturer Osram GmbH recently re-prices from the year-to-date, OSRAM energy-saving lamps price hasincreased by 25%. Dutch lighting manufacturer Philips has also announced that fromOctober 1 to raise prices. The reporter assigned to the list of financial subsidies toenergy-saving lamps in Wuxi, led downlights price not just like led high bay, before the column Osram overwhelmed by the absence of Philips just launched a model. Energy-saving lamps in the tin sales next year, still be able to maintain our current prices, it is difficult to say.

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.
