Abstract

For the comprehensive experimental course of light source and lighting specialty, the teaching system of high-power intelligent LED driver is developed, which is composed of Arduino board and high-power LED extended circuit board. The expansion board includes an indicator unit, an input unit and a high-power LED drive unit. The process of determining the key components of the drive unit is given in detail. The expansion board can drive 1~2 1W high-power LED within the system working voltage range of 8~12V, with stable output current and 88% peak efficiency. The relation curve between voltage difference and efficiency is given. For different loads, the efficiency is different even in the coincidence interval of pressure difference, which indicates that efficiency is not only related to pressure difference, But also needs to consider the load the voltage difference caused by debugging to achieve high efficiency. Experimental design is beneficial to enhance students' perceptual knowledge of high-power ledsdriver and enhance their design ability.
