  • LED Array Output Can be Modulated
  • Fits Many Commercially Camera Illumination Units
  • Compatible with the 30 mm Cage System

Developments in Light Emitting Diodes (LEDs) have resulted in devices that have significantly more power than halogen lamps and gas discharge lamps. Power levels are now high enough for LEDs to be a practical alternative to most high intensity lighting needs. LEDs offer several advantages, including better stability, longer life (up to 100k hours), lower cost of replacement, lower risk (no glass bulbs to break), cooler operating temperatures, and lower energy use than traditional light sources.

LED Arrays

The LIU series of LED light sources includes red, blue, green, and white LED arrays conveniently mounted in a 1.5" outer diameter housing that can be used for a variety of lighting applications. The housing can be readily secured in most optical mounts used in camera illumination units. Additional mounting options include two threaded holes on the rear of the housings, one M4 and one #8-32, as well as grooves running the length of the housing that allow the LED unit to be placed in a 30 mm cage system. The LED unit will be suspended by the cage rods but not restrained from moving along the optical axis of the cage system. To fix the position of the LED unit, sandwich it between two fixed cage elements (see the "Additional Images" tab for a possible solution). Each LED unit has a 4-pin power receptacle (M8 Straight Socket) on the rear of the housing and is shipped without a power cord. The 4-pin power receptacle allows for two channel control of the LED light source.

Each LED unit consists of 20 individual LEDs mounted in an array on a PCB board. When operating with 100 mA of current the Red, Green, and Blue LED units have an output intensity of more than 600 µW/cm2 and the white LED unit has an output intensity of more than 1700 µW/cm2, when measured at a distance of 100 mm from the LED array along the central axis.

Possible applications for this intense light source include photography, machine vision, and general research and development.

Power Supply / Cord Options

The LIU-PS is a 24 VDC power supply designed to power the LIU LED Arrays. This power supply is shipped with plug adapters that allow the unit to be plugged into the standard AC receptacles found in the USA, UK, and Europe.

The PAA630 power cord is a 2 m power cord with an M8 connector, compatible with the receptacle on the LIU LED Arrays, on one end and four bare wires on the other end. This allows the LIU LED Arrays to be easily connected to an existing power supply. The pin out information for this cord is displayed in the "Specs" tab while a sample control circuit is shown in the "Sample Circuit" tab. The intensity of the emmited light can be modulated by varying the output voltage of the power supply or by adjusting the control circuit.

Mounting Adapter

The AD38 double bored mounting ring holds an LIU Series LED Array in place with a single #8-32 setscrew. The outside of the adapter ring is Ø2".
