Light source, pulse controller and method for programmabale pulse generation and synchronization of light emitting devices

Abstract

An LED (Light Emitting Device) light source (), a pulse controller or pulse control module () for an LED light source, and a method are provided, for controlling relative timing and phase of LED light pulse generation and operation of peripheral devices, relative to a common timing reference. A system is provided comprising a pulse controller () for controlling synchronization of multiple LEDs () and/or other devices and peripherals (), relative to a common timing reference. The pulse controller () comprises a processor () that programmatically executes a time based sequence of digital control signals () from received inputs () indicative of a pulse generation sequence. The pulse controller provides for multiple pulse trains where improved control of relative timing of several events is required, such as for control of multiple high intensity LED light sources and synchronized control of peripheral devices such as detectors, for applications, such as, fluorescence microscopy and other spectroscopic applications.
