In combination with the local industrial distribution in Shenzhen, Idex focuses on LED and related industry testing solutions, including LED chips, modules, light strips, backlights, LED indoor and outdoor lighting, display and other finished products and LED drivers. Professional testing solutions for power supplies and other products cover the entire LED industry chain, providing high-performance test systems and solutions for major LED manufacturers, as well as high-quality instrumentation for LED test system integration vendors.
In order to make the audience more intuitive to experience the advantages of Itech products in this field test, they specially brought the LED light bar and the driving power supply as the object to be tested, and the staff conducted on-site testing and operation.
Itech IT6200 high voltage dual range DC power supply series
Idex uses the LED light bar test as an example. Based on the problems in the current test, Idex's solution is demonstrated. The core test instrument is the IT6200 series DC power supply specially developed by Idex for the LED industry. The supplier, which provides a stable and reliable power supply in the LED test, is tested in conjunction with an integrated LED photoelectricity detection system such as an integrating sphere test system. It can be seen from the oscilloscope that the power of this power supply is that when the LED test mode is selected, there is no inrush current generated at the start of the power supply, and a smooth current can be supplied to the LED to be tested, which has no effect on the LED life. .
The staff introduced: "This IT6200 series DC power supply also has the function of micro current mode. In this mode, the IT6200 series DC power supply is started, which can light the LED products to be tested in a very short time with a small current output, greatly improving At the same time as testing efficiency, capacity is maximized."
LED driver power test
In the entire LED circuit, the driving power plays an important role in converting the power supply to a specific voltage and current to drive the LED to emit light, and also plays a role in protecting the LED lamp, and its test is also very important. Idex brings the LED constant current source to demonstrate the test solution. The IT7321 AC power supply simulates the input side of the mains access drive power supply, and uses the CR8 LED mode of the IT8800 series electronic load to simulate the actual loaded LED on the output side. The true characteristics of the lamp.
