LED Light Bulbs

Introduction

Mentioning about lighting, people immediately think of all kinds of varicolored lighting in shops. Although these lamps are of different shapes, but their core part – the bulbs are actually mainly divided into three types: electric incandescent lamp and fluorescent lamp and gas discharge lamp. However, this pattern will be changed in the near future, because a new star in lighting industry - light emitting diode bulb is moving towards practical stage. Light emitting diode was invented in the 60s of the 20th century. In the decades that followed, its fundamental purpose is as indicator light for radio-cassette recorder and other electronic devices. In order to fully tap LED lighting's potential, in recent times, scientists have developed a new type of LED bulbs for lighting, LED air purification light bulb. This bulb has the characteristics of high efficiency and long life; it can continuously serve for 100,000 hours, which is 100 times longer than ordinary incandescent bulb.

It is estimated that globally, LED light bulb has a 9 billion pounds market prospect. In the huge business opportunities attraction, some LED light bulbs wholesale and retail manufacturers such as Philips have begun to invest millions of pounds for research and development of family-use LED bulbs. Scientists predict over the next 5 years, this light bulb is likely to become the mainstream lighting products of the next generation.

As we all know, 100 years up to now since the United States inventor Thomas. Edison invented incandescent lamp, people still continue to use technology invented by Edison to produce incandescent bulbs. The middle of the Light bulb is tungsten wire. When the current passes, the tungsten wire is heated to incandescent state and gives out light.

Luminous Principle

However, the light emitting diode bulbs have essential differences both in structure and in luminous principle from traditional incandescent bulbs. Diodes are elements in common use of electronic circuit, which consist of a semiconductor PN junction, electrode leads and tubes. Diode has two electrodes of PN junction so that it is called diode.

Light emitting diode is usually made from gallium arsenide, gallium phosphide or other semiconductor materials. It glows when it passes forward current. The luminous color depends on the material used, such as red, yellow, green and infrared light. Light emitting diode is often packaged by transparent plastic. Some light emitting diodes have three pins. According to pins' voltage, LED may give out two colors of light.

Technical Development of the Air Conditioner

There are following four aspects in the technical development of the air conditioner.

The first aspect: more comfortable

Early air conditioning just sends pure cold, like being thrown into the refrigerator in the air-conditioned room, which predisposes the air conditioning disease. Many businesses are now beginning to pay attention to this aspect,precision air conditioning gradually has the function of making the indoor air fresh, but that is not enough, the future air conditioning should go further in this regard. For example, the ideal indoor air conditioning should have the function of relaxing and relieving their stress; while the car air conditioning seems to have the effect of refreshing, wiping out the fatigue of driving car.

 

 

The second aspect: more intelligent

The advancement of science and technology makes people have increasingly high expectations of living standards and the air-conditioning is no exception. The intelligence may involve the following aspects: (perhaps more)

The phoneticization of operation: throw off those visible control equipments, such as the remote control, and air conditioning can be controlled by voice commands.

Functional diversification: In addition to the traditional refrigeration heat, dehumidification, humidification and new features can be joined. Detect temperature control: detect the temperature difference between the indoor and outdoor automatically to set reasonable cooling capacity and avoid all kinds of discomfort caused by people going out of the air-conditioned rooms, because of the temperature difference is too large.

Third aspect: more personalized

Consumers are now increasingly focusing on personalized products or special function need, or just want to show their own distinctive. In the future, the enterprises who can meet the needs of individual customers will be able to seize the hearts of consumers. The DIY air conditioning perhaps will become a popular word in the industry in the near future. Air conditioning industry can learn from the computer industry, to accept custom machine orders in the future, to meet consumer demand in appearance and color. Now, the appearances of many commercial air conditioning are increasingly colorful; and many air conditionings combine the functions of compatible audio and video. Many companies may have also noticed the personalization, but is just still in the exploratory period. Personally feel that the future "the music air conditioning" is worth being promoted and it may have the both the functions of download and play music, while the prospect of the video air conditioning is more limited, after all, the small screen is difficult to meet viewing needs.

 

The fourth aspect: more environmentally friendly

In fact, many companies have already taken actions, and some have done a good job. There is no doubt that the air conditioning will certainly go further in the aspects of lower power consumption, lower noise and less pollution.

 

www.airconditionings.cn has also constructed four state-level product performance- testing centers for packaged air conditioners, high-temperature-use air conditioners, air and water- cooled chillers and FCU & AHU. Moreover, a joint laboratory named Shenling-Siemens network-based professional lab for air-conditioning operating & monitoring system was set up in Shenling, which was the first lab of this kind co-constructed with Siemens in HVAC industry in china.

Basic Knowledge of Magnetic Component

As a matter of fact, magnetic material is an ancient and remarkably versatile functional material. As early as 3000 years ago, it has been recognized and applied, for example, the ancient Chinese natural magnet compass. Modern magnetic materials have been widely used in our lives, such as used in the transformer core material and computers with magnetic recording floppy. It can be said that the magnetic material is closely used related to information technology, automation, defense and national economy industries. And it is generally believed that the magnetic material is a kind of substance which is capable of directly or indirectly generated by the excessive element iron, cobalt, nickel, nickel alloys, etc. According to the characteristics of the substances in the external magnetic field, the magnetic materials can be divided into five categories: paramagnetic material, diamagnetic material, ferromagnetic material, sub-magnetic material, and diamagnetic substances. According to their use of basic performance, it can be divided into soft magnetic material, hard magnetic material, gyromagnetic magnetic material, short magnetic material, and pressure magnetic material.

 

There are many kinds of magnetic components, even in our daily lives, such as the radio bar magnet, radio magnetic core, TV magnetic cap, TV line output U-shaped core, deflection coil toroid, etc. There are more varieties with more different shapes.

The Impovement of LED Spot Lighting

LED point light source is a point light source, if the application is not good, and prone to glare from the whole industry chain, LED lights, radiator, drive, replace all of the high-pressure sodium lamps cost is not necessarily cheaper. Hangzhou Bulletin the Wu Ming Fan, LED spot light, director of the Institute, the LED lamp technology requirements, require advanced large-scale replacement.

 

In addition, the indicators of the evaluation of road lighting “illumination” are better than “brightness”. The various little throat professor pointed out that LED spot lighting can be replaced by the brightness of the light distribution to achieve the bat LED spotlights. The actual situation The brightness expensive measuring instruments penetration is not high, so for the convenience of the general lighting, rather than brightness. The evaluation system is flawed, difficult to guarantee the quality of LED lights.

Promoting the dimming LED spot light renovation project for the government of the most powerful companies also has their own views. "Subsidies to promote government can solve the urgent needs of the enterprise, but need the ability to save the government project eligibility successful product in the end simply different, and to rely on time to test. " said by a street lights manufacturer, who worried that the government palliatives, excessive administrative intervention may become secondary LED street light manufacturing industries. At the same time, he also pointed out that the face of the impetuous market, and companies need a clear direction of their own development, rather than the government-supported projects. Living in a green manner is not always as straightforward as we’d like it to be, certainly if the media is anything to go by. Obviously, given the choice, many of us would want to affect a positive change where the environmental issue is concerned but beyond this desire to do the right thing, it can be hard to know what changes you can make which will make a decent difference. www.progressive-hk.com was founded in 2007 as a professional manufacturer of LED Indoor & Outdoor Lighting Products.
