Embodiments of a light source include a substrate having a first end and a second end opposite the first end. A plurality of solid state light emitting diodes (LEDs) form an array, with the plurality of LEDs mounted on the substrate in a row between the first end and the second end. The plurality of LEDs further have a first edge LED and a second edge LED having a first encapsulation lens height relative to the substrate. At least one interior LED having a second encapsulation lens height less than the first encapsulation lens height is disposed between the first edge LED and the second edge LED. The spacing between the plurality of LEDs is substantially uniform.

Non-uniform lens array for illumination profile modification

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.
