【摘要】：半导体照明是公认最为有效的照明设备。当前的以半导体为基础的照明设备主要根据反激式变换器理论,采用以设定区间为主的半导体调光方式,通过调节半导体LED的正向工作电流控制发出的光能,调光范围虽然能达到标准,但是控制过程不灵活、效率低下,电流发生波动时,容易引起半导体发光光谱偏移,产生过多的热量,影响LED设备。提出一种可调节的半导体发光控制方法,通过分析反激式变换器电路的工作原理,定时调整电路信号占空比,对电路的最大输出电流值进行有节奏的调节,实现非必要限流节能;根据输出与实际结果的反馈,对信号的占空比进行校对,实现精确电流输出,达到半导体调光节能效果。经仿真数据检验,该方法可以较好地调节半导体发光中的光强度信息,起到了较好的节能效果。
[Abstract]:Semiconductor lighting is recognized as the most effective lighting equipment. The current lighting devices based on semiconductors are mainly based on the flyback converter theory, adopt the semiconductor dimming mode which is mainly set interval, and control the light energy emitted by adjusting the forward working current of semiconductor LED. Although the dimming range can reach the standard, the control process is inflexible and the efficiency is low. When the current fluctuates, it is easy to cause the semiconductor luminescence spectrum deviation and produce too much heat, which will affect the LED equipment. An adjustable semiconductor luminescence control method is proposed. By analyzing the working principle of the flyback converter circuit and adjusting the signal duty cycle of the circuit, the maximum output current value of the circuit can be adjusted rhythmically. Realizing non-essential current limiting and energy saving; According to the feedback between the output and the actual results, the duty cycle of the signal is calibrated to realize the accurate output of the current, and the effect of dimming energy saving of the semiconductor is achieved. The simulation data show that the method can adjust the light intensity information in semiconductor luminescence and has a good energy saving effect.
