摘　　要：随着100lm/W级白光LED的开发成功,白光LED在显示和照明方面应用普及化进程中又向前迈进了一步。主要介绍了白光LED的新应用——卡灯的结构和原理,及其在生活中的应用。并在电流为20A的条件下,距离为50mm处利用BM-7对其亮度进行测试,测试结果为平均亮度大于3400cd/m2,均匀度超过85%。With the successful development of the 100 lm/W- class white LED, it makes great strides forward in universalization in the display and illumination applications. The new application of the white LED, the structure and principles of Card Light as well as its application in life are described. Using the BM--7 to test its brightness in the distance of 50 cm when the current flow is 20 A, the average brightness more than 3 400 cd/m^2 and the degree of homogeneity over 85% have been achieved.
