A phototherapy or photobiomodulation process employing the application of electromagnetic radiation (EMR) to a living organism, typically a human being. The EMR is generated by one or more strings of LEDs and is programmed to emit one or more wavelengths, typically in the visible and infrared portions of the spectrum, the EMR in each wavelength being delivered in pulses having specified on-times, off-times, photoexcitation frequencies, duty factors, phase delays, and power amplitudes. A system for providing such EMR includes a microcontroller having a pattern library of algorithms, each of which defines a particular sequence of synthesized pulses, and an application pad, preferably flexible, containing the LED strings.一種光電治療或光生物調變過程，其使用電磁輻射(EMR)至通常為一人之一活有機體的施加。該EMR係藉由一或多個LED串產生，且經程式化以發射通常在光譜之可見部分與紅外線部分中的一或多個波長，以具有所指定的接通時間、斷開時間、光激發頻率、工作因數、相位延遲及功率振幅之脈衝而遞送每一波長中的該EMR。一種用於提供此EMR之系統包含：一微控制器，其具有一演算法型樣庫，該等演算法中之每一者定義一特定合成脈衝序列；及較佳地可撓性之一應用板，其含有該等LED串。
