        随着行业的继续发展,技术的飞跃突破,应用的大力推广,LED的光效也在不断提高,价格不断走低。新的组合式管芯的出现,也让单个LED管(模块)的功率不断提高。通过同业的不断努力研发,新型光学设计的突破,新灯种的开发,产品单一的局面也有望在进一步扭转。控制软件的改进,也使得LED照明使用更加便利。这些逐步的改变,都体现出了LED发光二极管在照明应用的前景广阔。

    LED被称为第四代光源,具有节能、环保、安全、寿命长、低功耗、低热、高亮度、防水、微型、防震、易调光、光束集中、维护简便等特点,可以广泛应用于各种指示、显示、装饰、背光源、普通照明等领域。

LED优点:电光转化效率高(接近60%,绿色环保、寿命长(可达10万小时)、工作电压低(3V左右)、反复开关无损寿命、体积小、发热少、亮度高、坚固耐用、易于调光、色彩多样、光束集中稳定、启动无延时;

LED缺点:起始成本高、显色性差、大功率LED效率低、恒流驱动(需专用驱动电路)。 相比之下,各种传统照明存在一定的缺陷。
白炽灯:电光转化效率低(10%左右)、寿命短(1000小时左右)、发热温度高、颜色单一且色温低;
荧光灯:电光转化效率不高(30%左右)、危害环境(含汞等有害元素,约3.5-5mg/只)、不可调亮度(低电压无法启辉发光)、紫外辐射、闪烁现象、启动较慢、稀土原料涨价(荧光粉占成本比重由10%上升到60~70%)、反复开关影响寿命;体积大。
高压气体放电灯:耗电量大、使用不安全、寿命短、散热问题,多用于室外照明。
