发光二极管,具有休积小、耗电少、光色多、耐振动、寿命长等特点;与普通二极管一样,具有单向导电的特性。利用它的这些特点和特性,可以做成各种机动车辆的显示及测试装置,新颖别致,引人注目。下面介绍几个小实例。一、简易测试器司机及修理工,常常采用试灯进行各种测试。而使用试灯,体积大,怕磕碰,携带不便,用发光二极管做个简易测试器,就可以克服以上的缺点(见图1)。制作时,发光二极管
Light-emitting diodes, with a small break, less power consumption, light color and more vibration-resistant, long life and other characteristics; and ordinary diodes, with one-way conductive properties. Using these features and characteristics of its can be made into a variety of motor vehicle display and test device, novel and unique, compelling. Here are a few small examples. A simple tester Drivers and mechanics, often using test lights for a variety of tests. The use of test lights, bulky, afraid of bump, carrying inconvenience, with light-emitting diodes to be a simple tester, you can overcome the above shortcomings (see Figure 1). Production, the light-emitting diode
