high power led driver and explosion proof lights

China’s semiconductor lighting industry is entering an important period of independent innovation, to achieve leapfrog development, LED industry in recent years, the rapid development of high-brightness LED chip high power led driver production this year is expected to be over 12 billion, a growth rate of 100%. According to reports, China has become the world’s largest producer and exporter of lighting appliances country. Global semiconductor lighting market sales of more than seven billion U.S. dollars, an average annual growth rate of over 20%, is expected will form a potential market of 500 billion to $ 100 billion in the next five to 10 years.

high power led driver and explosion proof lights

LED as a light-emitting light source of the explosion-proof lamps have a long life, energy saving, safety, environmental protection and other significant advantages, its power consumption is only 1/10 of the ordinary industrial explosion-proof lighting, small size, light weight, low energy consumption, instant start, can withstand high strength mechanical shock and vibration, and other obvious advantages, but due to various reasons such as LED costs is also promoting its application. However, all people in the industry are quite optimistic about the future of the industrial use of LED explosion-proof lighting high power led driver , that will set off a new LED light source alternative movement.

With the domestic LED lighting manufacturing industry in 2011 to an oversupply serious oversupply in 2012 and the emergence of a large number of companies to limit production, discontinued, closed, closed down, even my boss Paolu phenomenon, many LED explosion proof lighting manufacturers have sights broader specialty industrial explosion-proof lighting market in Europe and the United States. Of course, there is a great attraction for the huge European market demand for LED explosion proof lighting manufacturer, but not so easy to enter the European and American markets, in addition to the well-known LED patent threshold, ATEX explosion-proof certification is interested in the European and American markets, manufacturers must the face of another technical barriers to trade. According to the reporter, the official authorized by the EU in the domestic qualification awarded ATEX certification EU the authorized announcement institutions (NB1254) a company called Swiss QS certification, they have accepted a number of well-known domestic LED lighting high power led driver enterprise application ATEX categorysome products have passed the rigorous testing of explosion-proof lab, is about to get a the ATEX certification awarded by the Swiss QS certification company, to make the product the first step into the European explosion-proof lighting market.

How to increase the duration of high-power LED driver

 

Essential as power devices, electrolytic capacitors must be able to long-term work in high temperature environment, this test is very grim. General-purpose aluminum electrolytic capacitor life span of only 4000 hours to 5000 hours, half life, and at high temperatures is far from meeting the requirements of the long life of LED lighting, and thus the aluminum electrolytic capacitor has become the bottleneck of the high-power LED driver. The structural design of aluminum electrolytic capacitors, the advanced nature of the manufacturing process to determine its service life. Aluminum electrolytic capacitors for LED lighting special emphasis on long life, high temperature and small.

 

The high-voltage driver chip may be one of the better solution HVLEDs constant current drive power. Some chips are ideal, but is too expensive to buy in China, used to produce general-purpose high-power LED driver costs are high. In recent years, China’s domestic integrated circuit design level rising, but there is a very good price and market competitiveness, to downstream manufacturers for the production of technical solutions and technical support in place.

 

In addition, the LED light source lamp bead is a major breakthrough. The rising star of the LED family of high-voltage LEDs (HV LEDs) have sprung up everywhere, the VF high voltage, the IF current working conditions completely subverts the traditional low-voltage (LV LED) LED VF low voltage, the IF current requirements. Led high bay lighting due to the HV LEDs SOP may reduce the shape of the heating, lighting structure may tend to be more to save cooling materials, greater than 270 degrees light-emitting, low-cost, light weight.

So, really high quality LED driver power supply should have what kind of features or to meet those requirements? Tektronix summed up the following main aspects:

 

(1) high reliability and life: the life of the drive power to the life of the LED relative to adaptation, in particular, like the drive power of the high power led driver installed at high altitude, maintenance inconvenient, the maintenance cost is also large;

(2) High efficiency: the structure of power supply installed in the LED lighting, which is especially important. LED luminous efficiency of high power led driver temperature decreases, so the LED heat dissipation is very important. High efficiency power supply, the loss power, heat lamps, reduces the temperature rise of the lamps is beneficial to delay the LED light failure.

(3) high power factor: With the increasing demands of the community’s quality of power supply, people are increasingly concerned about the electrical equipment of power quality and harmonics. Such as the EU has issued standards require power greater than 25W power supply must have a power factor correction circuit. And many other countries for 30 ~ 40W LED driver power supply, It is said that soon will also may power factor of a certain indicator.

(4) constant current driver: It is now common, there are two: one is a constant voltage source for the constant current source, each constant current source separately to each high power led driver. In this way the combination of flexible, all the way to the LED fault, does not affect the other LED’s work (led high bay lights), but the cost will be slightly higher.
