技術說明

本發明以白光Light Emitting Diode為主要的發光系統再加上多種發光光譜發光二極體LED之操作特性。以直流模式與脈波模式二種，對不同電壓、電流與脈波波形驅動，同時進行混光及其電氣與發光特性；包括：發光效率、光譜能量以及對於色度與演色性之影響。 LED以 (Pulse-Width-Modulation，PWM)脈波寬度調變在DC Mode與PWM Mode脈波寬度調變時，LED色彩之眼色性CRI與色溫CCT偏移狀況。用脈波寬度調變Pulse-Width-Modulation，以Shift Wavelength技巧，PWM搭配ACC自動電流控制回授電路Automatic Current Control System及AEC自動電壓控制回授電路Automatic Electronic Control System，進行調光及光譜位移控制，修正LED色彩之(演色性)，達到外在溫度影響仍然有最佳(高演色性)表現。 This invention relates to white Light Emitting Diode light-emitting system as the main emission spectrum together with a variety of light-emitting diodes LED's operating characteristics. In DC mode and pulse mode, two kinds of different voltage and current waveforms with the pulse-driven, simultaneous mixing and its electrical and luminescence properties; include: luminous efficiency, color and spectral energy and color rendering for the effect. The LED (Pulse-Width-Modulation, PWM) pulse width modulation in DC Mode and PWM Mode When pulse width modulation, LED color of CRI and color temperature CCT offset condition. With pulse width modulation Pulse-Width-Modulation, to Shift Wavelength techniques, PWM current control with automatic feedback circuit ACC System and the automatic voltage control feedback circuit AEC System, to control dimming and spectral shift to amend the color of the LED (CRI), to the external temperature is still the best (high CRI) performance.
