Although LED lighting is the general trend, due to price and cost factors, the development of the domestic lighting market is still not as fast as expected. On the contrary, due to the high demand for energy saving in overseas markets and the high price acceptance of LED lamps, domestic LED lighting products are currently exported to over 70%. This is probably the general feeling of the industry for the current domestic LED market. But at the 2013 China (Ningbo) LED Lighting Exhibition held at the Ningbo International Convention and Exhibition Center last week, the author saw another prosperous scene. The exhibition hall of more than 20,000 square meters attracted hundreds of well-known LED lighting companies. Coming to the exhibition, tens of thousands of company executives, market personnel, engineers and LED industry media actively interacted. It is understood that due to continued government investment in recent years, the domestic LED lighting market has developed rapidly. At the same time, packaging, testing and other technologies are steadily improving and improving. Among the many exhibitors at this exhibition, in addition to LED lighting product manufacturers, there are also many internationally renowned test and measurement equipment suppliers. They use advanced test instruments and test systems. Become the backbone of the development of LED lighting industry.
In the emerging LED industry, there are so many different characteristics of light-emitting diodes from other light-emitting components. What are the advantages of the instruments and equipment used for testing? I learned from the ITECH booth with a comprehensive test solution covering the LED industry chain that LEDs have the special property of forward bias, that is, LEDs will only emit light when turned on in a certain direction. This characteristic determines The CV and CR test modes of traditional electronic loads are not enough to fully simulate the true characteristics of special LED lights. Then, the application of the test to the LED drive power will affect the test results. And the IT8800 electronic load series products exhibited by ITECH have increased the diode on-voltage setting, and have the industry-leading CR-LED mode, so that when the voltage applied across the electronic load is greater than the set diode on-voltage, the electronic The load only started to work. In this way, ITECH IT8800 electronic load series can simulate the true characteristics of LED lights, which can be used in the test of LED drive power to ensure that the test results are accurate and reliable.
ITECH is a member of the B & K-Precision Group, the fourth largest instrument company in the United States. The B & K-Precision Group was established in 1951. After sixty years of development, it has become a leading instrument manufacturer of world-class brands. Itech has inherited the excellent technical background of the group's instrument manufacturing for many years, devoted to the research in the field of power supply and power supply testing, and developed a series of high-performance automatic test systems, high-power electronic test instruments such as power supplies and electronic loads, which are widely used in various field. In terms of products, ITECH mainly focuses on power supply, electronic load and some test systems and test software around power supply testing. In the LED drive power test, in addition to the electronic load specifically for LED testing, ITECH has also developed a series of stable and reliable AC power products. The IT7321 AC power series brought at this exhibition has a smart appearance and Super high stability wins. It is understood that the bulk of the AC power supply has always had a certain impact on the application. Not only is it not easy to move when the desktop is used, but it also occupies a large space after being installed on the shelf. The AC power supply I saw at the ITECH booth, the 300VA model product is only 1/2 2U ultra-small size, looks small and beautiful, easy to move, suitable for laboratory use. The application of this AC power supply in the field of LED testing can be described as very extensive. The maximum output capacity of a single machine can reach 6KVA, a wide frequency adjustment range of 45-500HZ, and an adjustable phase angle of 0-360 °. It is used in LED drive power supplies and LED finished lamps. And can be used as a stable, reliable and powerful power supply in the integrating sphere test system. For the testing of LED luminaires, the AC power supply is required to simulate the non-ideal AC ripple in the real power grid to verify the stability of the luminaire. The staff demonstrated IT7321 AC power supply to simulate surge, notch, and high frequency noise , Frequency instability and other functions have attracted many professionals to stop and watch.
ITECH has an independent R & D organization and huge technical advantages, first-class manufacturing plants and close technical exchanges and cooperation with internationally renowned companies, and is in a leading position in the industry and some high-tech test technologies. At the exhibition site, Itech's DC power supply for LED lighting module testing and aging test system also attracted attention. LED mode / Low current mode and other terms guide the LED industry related engineers and manufacturers to further explore the various problems and solutions in the LED test. As a leading supplier of test instruments, ITECH provides complete test solutions such as "Invisible Hand" to provide the best solutions for the LED industry.
