发光二极管是一种把电能直接转换为光能的固体发光器件。它以其体积小、耗电低、响应速度快、亮度调整灵活、使用寿命长、稳定性好、抗震性强等优点广泛应用于工农业生产和家用电器等设备上。下面介绍几种常用的应用电路。1.指示用光源在不需要高亮度的场所下,可采用发光二极管作指示电源。例如示波器的标尺照明、收音机的
Light-emitting diode is a direct conversion of electrical energy into light-emitting solid-state light devices. Its small size, low power consumption, fast response, flexible brightness adjustment, long service life, good stability, strong seismic and other advantages widely used in industrial and agricultural production and household appliances and other equipment. Here are some commonly used application circuit. 1. Indication of light in the place do not need high brightness, light-emitting diodes can be used as an indicator of power. Such as oscilloscope ruler lighting, radio
