摘要
LED是一种发光二极管,它作为第四代照明光源也被称为绿色光源,因它具有节能、环保、体积小、寿命长等特点而被广泛应用于电子设备、普通照明、显示屏等众多领域。而且随着其技术的不断更新,已经开始进入寻常百姓家,大有替代白炽灯甚至节能灯的趋势。本文采用的是恒流驱动电路的解决方案,选择了PT4115的驱动芯片,具有成本低、电路简单、高效的特点,适合LED产品的市场化发展需求。
LED is a light emitting diode, as the fourth generation lighting source is also known as the green light source, due to its advantages of energy saving, environmental protection, small size, long life and other characteristics, are widely used in electronic equipment, general lighting, display and other fields. And with the constantly updated technology, has begun to enter home of common common people, is replacing incandescent or energy-saving lamps trend. This is a constant current driving circuit solution, choose the PT4115 driving chip, has the advantages of low Cost, simpie circuit, high efficiency, suitable for LED products to the development needs of the market.
