The green light increased demand for high-power white LED applications led bulbs qualify

LED Panel Light source to be the main cause of all ages, is nothing more than the product of long life, light – high power conversion efficiency, material properties can be fitted in any plane. In the development of the day-to-day lighting source, due to the need to achieve practical lighting needs, the original to indicate that the use of LED lighting applications will not be able to correspond directly from the chip, package, carrier board, production technology and an external circuit must be strengthened, in order to achieve the high power required for lighting purposes, high brightness lighting utility.

Observed on the level of market demand for white LED lighting applications market development, it can be said future higher dosage of the project, but to use utility, white LED lighting applications must focus on functional improvement. One is to strengthen for the LED chip led bulbs, e.g., to increase their optical – electrical conversion efficiency, or to increase the chip area, to allow a single LED light emission amount (flux) reaches its design limit. Second, is a compromise design program, the more difficult to continue to increase the area of monolithic LED chip under the premise switch to multi-chip LED chip is packaged in a light source module, but also the practical technical solutions can be achieved close to the aforementioned method .

LED light-emitting principle:

LED industry in China started in the 1970s. After 30 years of development, China’s LED industry has initially formed a relatively complete industrial chain, including the production of LED epitaxial wafers, LED chips preparation, LED chip packaging and LED product applications, including.

LED lighting LED III – IV compound, such as GaAs (gallium arsenide), GaP (phosphide gallium), GaAsP (gallium arsenide phosphide) and other semiconductor made of, its core is a PN junction. So it has the general PN junction IN characteristics, namely the forward pass, reverse-blocking breakdown characteristics. In addition, under certain conditions, it has a light emitting characteristic. Forward voltage, electrons from the N-region into the P region, the injection of holes from the P region N region. Into each other regional minority carriers (minority) part of the compound and shine with the majority carrier (number of children). Assume that luminescence occurs in the P region, the injected electrons and valence band holes directly composite and light-emitting, or first captured by the luminous center hole recombination. In addition to this light-emitting compound, also some electronic non-luminescent center (the center between the conduction band, dielectric tape near the middle) capture, and then with the hole recombination, the energy of each release is not and can not form visible.

1 Introduction.

With the rapid economic development in recent years, the car’s design and manufacturing technology are also increasing, also gradually rich functionality of the car, the car has become an essential part of people’s daily lives. However, the possibility of driving a vehicle traffic accidents occur at night or in low-light situations, and can account for about 27% of the total traffic accidents, and most of the time there will be personal harm. So 3w led grow driving at night must have good lighting.

2 car lamps.

Automotive lamps from the 1880s, the world’s first light auto lighting classic cars hanging gas lamps to the development of the first electric lights in 1912. Early automotive incandescent lamps, the lighting is dim, in the situation of the increasing number of vehicles and continuously improve the speed, incandescent can not meet the day-to-day needs of the lighting, car lights and the development of higher brightness tungsten halogen lamps high-intensity discharge lamps, brake lights, turn to a series of lights, rear fog lamp types, played a key role in order to avoid driving at night, when the rear-end or turn collided. Lighting technology with improved productivity is also gradually developed, including light-emitting diode technology (Light Emitting Diode LED High Bay Bulbs ), especially in automotive lamps automotive lamps. Automotive design in recent years, more and more use of LED 3w led grow lights, modeling is more and more elegant, and the combination of various lamps use more to lead the trend and direction of today’s automotive lighting development.

3 car rear combination lamps of basic theory.

3w led grow for new year

The cars in the process of driving, the rear combination lamp can be obvious characterization of the car driving, docked and the steering state, so that a variety of vehicle driver to make a more reliable adjustment, safe driving. Modern automobile rear lamps commonly used form of modular lighting the lights of the various functions in the same light body inside nice and easy car driver identification. General rear combination lamps, including brake lights, rear fog lamps, cornering lights, reversing lights, rear position lamps, these types of lights have their role, as follows:

The brake lights: the brake lights (brake lights) is mounted on the rear of the vehicle on both sides when driving the brake pedal is depressed, the brake lights that lit the red light to remind the vehicles behind Note, do not rear-end . Brake lights that go off when the brake pedal is released when the motorist.

Rear fog lamp: car rear fog lamp is low visibility in fog, snow, rain or dust diffuse environment, easy to find and installed in the rear of the vehicle to the rear of the vehicle to other road traffic participants, luminous intensity more than taillight large.

Turn lights: turn signal is open to vehicles and pedestrians around prompt attention to the important indicator in the motor 3w led grow vehicle steering.

Reversing lights: lighting behind the vehicle roads and warning other person using the road, the vehicle is reversing or about to lights, color is white.

Rear position lamps: commonly known as a small lamp, is mainly used to indicate the presence of the car and broad width, easy to make judgments of the other vehicles in the car will be and when overtaking.

 

led grow light fixtures in China

Ceiling lamps, as the name suggests, the lamps above installed horizontally at the bottom is completely attached to the roof on so called ceiling. Its ordinary white light bulbs, fluorescent lamps, high intensity discharge lamps, halogen light source. The most popular on the market is the LED ceiling and Power LED Flood Lights, gorgeous appearance the LED Ceiling adsorbed or embedded in the roof ceiling lighting, indoor main lighting equipment.

With home decoration heat continues to heat up, the ceiling lamps changes with each passing day, is no longer confined to the front of the single lamp, but to diversify development, drawing on both the luxury and style of the chandelier, ceiling installation avoid the defect the shorter room can not be installed large luxury lighting. To make a more comprehensive understanding of the ceiling lamps led grow light fixtures, today I gave you in detail about the ceiling lamp of knowledge, in order to design and optional ceiling lamps reference.

(A) ordinary ceiling lamps

led grow light fixtures in China

1 ceiling lamp shape
Ordinary ceiling lamp shape although there are many, but the most common is round or square, the complex is more variety of bizarre Crystal Ceiling.

2 lamp ceiling lamp
Most of its lamp T5 fluorescent bending, many different specifications, mainly in the following led grow light fixtures.

3 ceiling lamp power

Ceiling lamp power and not clearly defined, and its power is most commonly used for 10W, 16W, 21W, 28W, 32W, 38W, 40W.

(B) the problems and shortcomings of the ordinary Ceiling

Low luminous efficiency.

The entire ballast energy saving lamps lighting effects only 55lm /, the most high-power U type only 80lm / W. And because all of these Ceiling mostly used T5 lamp, bending into various shapes. However, regardless of the final bend into shape, it is 360 degrees luminescence, wherein upward 180 degrees of the light must be reflected back only into useful light, and this reflection process will lose a lot of light. So, later made into lamps light efficiency of at least want to make a 70% discount. Is the light efficiency but also multiplied by 0.7. And when in actual use, the luminance decay with time quickly. For example the tricolor lamp T5 YH32RR16 of a Philips 32W ring, the color temperature for 6500oK, its luminous efficiency to 67lm / W, the total number of lumens 2150lm, in fact, only 70% of the light can take advantage of. Is 1500lm.

2 containing mercury

The low boiling point of mercury, at room temperature, was evaporated. A waste discarded fluorescent lamps broken, immediately distributed to the surrounding mercury vapor, the moment the mercury concentration in the ambient air can be up to 10-20 mg / cubic meter, exceeding the national maximum allowable concentration of mercury in the air (0.01 mg / cubic 1000-2000 m) times the body once inhaled 2.5 grams of mercury vapor that is life-threatening. And high penetration of liquid mercury, into the ground immediately after they fell into the underground pollution of groundwater led grow light fixtures. 1 mg of mercury is enough to contaminate 5454.5 kg of drinking water, to make it up to meet the safety standards for drinking water. Now desperate to promote energy-saving lamps, it is really irresponsible to our children.

3 low life

Energy-saving lamps in accordance with the phosphor divided: the mixed powder, halogen powder, the three primary colors. The life of halogen powder; hybrid the powder life in 4000 to 6000 hours 3000 to 4000 hours; the tricolor known more than 8000 hours.

Clearly, LED has a very significant advantage in the energy efficiency and the working life. LED bulb requires only one third of the electricity consumption, can provide almost the same light emission amount with conventional incandescent and fluorescent lamps. Compared with the more mature technology-based products, the service life of the LED bulb is expected to more than 20 times higher. LED bulbs in the solid state components than the relatively fragile traditional lighting technology, provide better protection of mechanical damage. Together, these features provide attractive investment returns (ROI) for the users of LED lighting products, especially for maintenance and bulb replacement is more difficult and / or expensive commercial and industrial applications chinese led manufacturer.

In the past about 150 years, the lighting industry has developed into a large-scale production industry based on standardized bulb, lamp design has inherent outdated. Consumers find themselves often use the same new products to replace short-lived in the product. This trend with a small number of large manufacturers are inseparable, they are through to the hundreds of millions of low-cost manufacturing of a product to meet the needs of the market.

With the lighting industry’s transition to Power LED Flood Lights technology, whether this business model can continue to maintain their best interests? And whether it is able to take advantage of the basic advantages of solid-state lighting chinese led manufacturer?

May be associated with a longer working life of the technology is equally important, the greater efficiency and a more solid design is the LED having architectural flexibility. For example, the lighting designer can select a point light source LED lights to make it around a shape distribution, rather than the light source together diffuser and mask will be distributed to where it is needed. These features give lighting designers unlimited freedom of design, innovative way to design the light source. Product developers LED lighting products can be made ​​into any shape, or lighting embedded in building materials, walls or furniture. They can be more accurate directional light source, or more easily control its intensity or color, to create a dynamic lighting environment. Some manufacturers have developed a windows prototype, which is transparent in the daytime and by clever use of the material of the LED chinese led manufacturer, and different refractive indices, which will emit light at night.

 

 

To do appropriate measures and the development trend for led industry

At present, traditional lighting still occupy absolute market share advantages. LED lighting market penetration is still very low, the latest information indicates that the LED lighting market penetration is only about 7%. The reasons are mainly the following:

To do appropriate measures and the development trend for led industry

1. The high price of LED lamps.

2. promotion lag.

3. Retail Distribution does not put in good force.

At this stage, led industry lighting companies should not only focus on application-oriented product development, but also pay attention to brand building. At present, most LED lighting companies play the “green energy”, “low attenuation”, “long life” concept, but it has not be acceptable to the majority of consumers. The market are flooded with cheap inferior products, which seriously affect brand of LED lighting credibility.

Businesses want to do appropriate measure.

2012 was a reshuffle year for terminal dealers, “the strong get stronger and the weak are eliminated,” the general trend is hard to change. Can I get through in this winter? and it depends on the financial strength of the business and the business model of the lamps. On the circumstances that the country’s major flow decrease each year, if the business still wait for the client to send home, it is undoubtedly the worst response. While for the led industry lighting companies, they are also facing the problem. The pipeline provider can not be found in the terminal. At present, many LED Tunnel Light companies have chosen to open outlets. Such as shellfish crystal semiconductor lighting in Shenzhen Parc Oasis Lighting City opened factory outlets directly.

LED pipeline construction trends

How to blaze a way out when one enterprise does not form the industry standard, and in a full of the cohabitation quality LED market? Quality is the key to victory, and also product reputation and brand symbol, and LED terminal market in the next competition will be the brand competition .

1, the development of led industry store.

2, on the Major Lamps City or city building stores sell lamps as a trial. Or operated in cooperation with local core dealer, but in the short term the mode of promotion efforts should not be too great.

3, part of the LED lighting business cooperate with the well-known brand  and well-known brand of Direct stores Distribution.

supernova led grow lights inhibition of urban crime

The American Austin City Police Department and Austin Energy Energy Board cooperation to protect the residents of the city. Since a significant increase in violent crime rate in mid-2011, the two institutions plan fitted with LED lighting, the prevention of crime in the U.S. city of Austin, the three most dangerous locations. supernova led grow lights are normally used in these kinds of projects.

Austin Energy spokesman Carlos Cordova, announced that a well-lit place is usually not an offense has been committed, because when you want to do bad things and nobody seen.

In accordance with the requirements of the city’s Police Department, Austin Energy erected 25 LED lights. The new LED bulb illumination is brighter than the old bulbs. Cordova said good lighting environment, people can be assured of recreational activities, no need to worry about security issues.

supernova led grow lights are also some kinds of inhibition of urban crime.

supernova led grow lights inhibition of urban crime

Austin, 8 and 9 of the street lighting test results are very successful, this lighting project is one of a series of policies against urban crime. The growth of violent crime by 15 percent from 2011 to January 2012, July, violent crime only grow by 7.8% next city a larger project, 70,000 lamps will be updated by Austin Energy budget expenditures.

It is reported that this new LED lighting products to reduce the crime rate, the earlier countries into Japan, called LED guard against light, has been gradually applied in street alleys to replace fluorescent lamps mainly traditional street lights. supernova led grow lights are also one of the important models for the modern cities to show the updated technology. Also, you could find led flood lights in these big cities, for example, in Shanghai, China, thousands of LED Flood Lights are installed in different applications, projects.

In addition, studies have pointed out that the blue light, that people can more calm, and some of the LED light will also guard against taking blue, white separate configuration. Based on the technology now, using LED is saving more money and better maintence cost, also, the life span of led products would be about 50,000 hours, much longer than any other lighting products.

 

Be optimistic about the LED industry

In a short period of time, there are more than three enterprises who have closed their doors due to financial crisis. But at present, it came the Haobo photoelectric involved financial crisis. The operating income of Haobo Optoelectronics Co., Ltd., in Shenzhen had about 200 million yuan last year, just one year on the market, the market have spread-ed the message of shutting LED industry down.

be optimistic about led industry

Operational problems caused the enterprise funds strand breaks

On November 5, the media reports said, Haobo photoelectric closed for huge amount of money owed ​​suppliers and employees wages. After the report came out, Haobo photoelectric chairman Zhao Hui responded that the enterprise did not lay-off before, just days off. He also promised that he will resolve the wages and salaries as soon as possible, and the gradual repay the amounts owed ​​to suppliers.

Reporter does not contact Zhao Hui, but we contact one of the shareholders of the Haobo photoelectric Wang, Mr. wang introduced the predecessor of Haobo photoelectric was founded in 2006-a the technology company. From 2008 to 2011, it has been very good business development trend. Last year’s sales reached $ 2 billion.

At present what problem does the company encountered? ” The main problem is money. ” Mr. Wang said, In September, the company delayed wages, and in October the company capital chain had problems, ” money does not move, and can not buy materials “. Mr. Wang thought that the main reason that lead to company capital category to rupture is the confusion of management, financial turmoil. It is the management problem caused the enterprise capital chain rupture. According to introducing, the orders in Haobo photoelectric have been very abundant, the main cause of factory production shutdown is that the company owed suppliers’ money, which LED Panel Light to the supplier for collective broken.

“Is there any possibility to return for work?” Mr. Wang said: “most of the workers were gone, enterprises will not restart, the company must wait for introducing new investors, there will be a new progress. ”

Mr. Wang said he was very optimistic about the LED industry. From the industry photoelectric performance in recent years, LED development trend is benign, once the company start moving, he has the confidence to repay supplier’s payment gradually.
