Light source, LED pulse control and method for programmable pulse control and synchronization of lighting devices

摘要

Providing an LED (light device) light source (100), a pulse controller or a pulse control module (130) for an LED light source, and a method to relate the relative timing and phase of LED light pulse generation and peripheral device operation to control a common timing reference. A system is provided that includes a pulse controller (130) to control the synchronization of multiple LEDs (144) and / or other devices and peripherals (164) with respect to a common timing reference. The pulse controller (130) comprises a processor (131) which executes a time-based sequence of digital control signals (141) from received inputs (121) which indicate a pulse generation sequence. Pulse control provides multiple pulse trains where improved control over the relative timing of multiple events is required, such as for controlling multiple high intensity LED light sources and for synchronized control of peripheral devices such as detectors for applications such as fluorescence microscopy and other spectroscopic applications.
