台灯稳定高效，功能丰富，能够满足家庭实际应用的要求。-LED (light emitting diode) as a novel light source, with high efficiency energy saving, environmental protection, long life and other sources can not match the advantages of lighting technology represents the future direction of development. This paper presents a AT89S51 microcontroller to function as the core of the home white LED lamp system, using high-power LED constant current driver programs PT4115, LED lamp can be realized multi-level PWM dimming control the same time, the system both time calendar, temperature measurement, liquid crystal display, sound and light alarm clock and many other features. This article details the hardware and software design process. Experiments show that the multi-function LED lamp stable and efficient, feature-rich, practical applications to meet the requirements of the family.
