[Source: Gaogong LED 's " LED Good Products" magazine May issue reporter / He Wei] With the continuous development of LED lighting, the policy dividends are frequently introduced, and LED lamps with advantages such as energy saving and environmental protection are being moved from indoor lighting to indoors. The application market for lighting has gradually penetrated. Because LED lighting systems have more complex principles, spanning optical, electrical and thermal fields, the life of LED lamps is affected by factors such as light source, power supply and heat dissipation structure.
According to previous reports, one of the direct reasons for the main impact of LED lighting products is that LED lighting fixtures have a short life span and do not meet consumer expectations.
The main factors leading to the short life of the lamp include the low efficiency of the driving power supply, resulting in low conversion of the lamp performance. Or the instability of the output current and voltage affects the lighting quality, which makes the green energy saving advantages of LED lighting greatly reduced, affecting the popularity of the market. .
Therefore, in the entire LED industry chain, from chip to package, drive power to finished products, all the photoelectric indicators of the products need to be tested to improve product quality and improve production efficiency.
LED driver power test solution
In order to ensure the high reliability of the LED driving power supply, it is necessary to test various photoelectric indicators of the product.
"Idex combines the characteristics of LED driver and has developed a professional LED driver power test solution with more than 60 years of experience in instrument manufacturing." Victor Tolan, CEO of Itech Group, said that the traditional electronics on the market The load does not fully meet the test requirements of the LED constant current source, and voltage and current instability may occur.
In the past few years, Idx has conducted in-depth research in the R&D centers in the United States and Taipei, and has made breakthroughs with advanced technology. Victor Tolan pointed out that due to the on-voltage of the LED, there is a large ripple in the output current and voltage waveforms. For such characteristics, only the electronic load of the professional test LED constant current source can make the test result accurate and ensure the quality of the product.
Since then, Aidex has launched an electronic load for professional testing of LEDs - the IT8800 programmable high precision electronic load series. It is understood that this series has a CR-LED function that professionally tests the LED constant current source. This function increases the diode turn-on voltage setting so that the electronic load is only applied when the voltage applied across the electronic load is greater than the turn-on voltage of the diode. , completely realistically simulate the principle of diode operation. At the same time, the actual load condition of the LED driver can be simulated for the LED power supply test, and it is applied to the simulation LED lamp. The operation is also simple and convenient. It is only necessary to set the on-voltage value of the diode inside the instrument and set the CR value of the load to fully simulate the true characteristics of the LED lamp, so that the test result is more accurate and the quality of the product is ensured.
“In the LED driver test, the electronic load can test the load performance of the power supply. A comprehensive AC power supply is required for comprehensive inspection and evaluation.†Victor Tolan said that the AC power supply exists to simulate the real power grid and test the LED driver. The ability to stabilize when the real grid changes.
In addition to this function, the ITECH IT7300 AC power supply series can simulate the glitch and notch, as well as the phenomenon of noise interference in the real power grid, and fully detect the stability of the LED driver.
