The IEC 62595-2-2 standard specifies in detail how to measure the optical and electrical performance of LED light-emitting strips in LCD backlight components. The measurement of optical performance includes parameters such as luminous flux, luminous intensity, and color temperature, while the measurement of electrical performance involves parameters such as power supply voltage, current, and power. These measurements help to comprehensively evaluate the performance of LED light-emitting strips, ensuring that they can provide stable and uniform backlight effects in practical applications.
