SAP Ltd. appointed European Master Distributor for Spectrum Illumination products. 

Ring Lights

Ring Light/Dark Field (RL/DF Series)
Spectrum Illumination Series RL/DF Ring Lights are used for bright field and dark field applications. Dark field lights are used to illuminate edges and surface defects. The four arrays on the RL/DF Lights can be adjusted from 0-90 degrees so that edges and features are illuminated properly. Because the RL/DF Light is adjustable the end user has greater flexibility in respect to working distance than other non adjustable dark field lighting products. RL/DF Lights run on industry standard 24 volt DC power. RL/DF Lights also incorporate a high speed low current sourcing input for strobing the light directly from a vision sensor or PLC output. The strobe line can be tied directly to 24 volt DC so the light remains on constant. All RL/DF Lights use industry standard 4 pin M12 Eurofast quick disconnect cables and are supplied with a 4 meter mating cable.

Ring Lights

RL - Monster Series

RL - Monster Series
Spectrum Illumination Monster Series Ring Lights are used primarily for bright field illumination. The RL2.5 model can also be used as a spot light for both bright field and dark field applications. The Monster series Ring Light was designed to be used for applications requiring a large area of coverage and/or a long working distance. Typically they are used in applications that need a lot of light and can be mounted 12” (304.8mm) to 20’ (6096mm) from the desired area of interest. LED optics and diffuser options are also available on these lights which makes it possible to obtain closer working distances and/or large coverage areas. The Monster Series Ring Light can be purchased in standard diameters starting at 2.5” (63.5mm) up to 30.5” (774.7mm) Every light is designed in a heavy duty industrial enclosure. The Monster Series Ring Lights are supplied with our DIN rail mount 24VDC High Speed LDM (LED Driver Module) Adapter and 4 meter 5 pin reverse keyed M12 Eurofast quick disconnect cable. The LDM adapter has both PNP and NPN strobe inputs with a 3 microsecond response time and is also available with either variable potentiometer control or 0-10VDC analogue control.

RL - Monster Series

Back Lights

MBL - Monster Series
Spectrum Illumination Monster Series Back Lights are designed to create high contrast silhouettes for high speed Machine Vision Applications. Monster Series Back Lights can also be used to create diffused front lighting because of the high intensity of the LEDs. The Monster Series Back Lights are 5 - 10 times brighter than standard back lights depending on the color. They have been used in high speed bottling and canning operations as diffused front lights with complete success. Sizes currently available include 1" x 2", 1" x 4", 2" x 2", 4" x 4" and 4" x 8" but all Monster Series lights (Spot Lights, Ring Lights, Linear Lights or Washdown Series lights) can be ordered with the option by adding "MB" to the front of the part number. Every Light is designed in a heavy duty industrial enclosure. Monster Series Back Lights use a specially designed optic that disperses the light intensity evenly. When viewing the light without the diffuser the individual LEDs actually look brighter from an angle view than it does looking straight on. This is why there are no hot spots and is what makes the Monster Series Back Light superior to other LED back lights. Monster Series Back Lights are supplied with our DIN rail mount 24 volt DC High Speed LDM (LED Driver Module) Adapter and 4 meter 5 pin reverse keyed M12 Eurofast quick disconnect cable. The LDM Adapter has both PNP and NPN strobe inputs with a 3 microsecond response time and is also available with an optional variable potentiometer control or 0-10VDC analogue control.

Back Lights

BL - Standard Series

Spectrum Illumination Standard Series Back Lights are designed to create high contrast silhouettes for Machine Vision Applications. Standard Series Back Lights can also be used to create front lighting in cases where minimal lighting is needed. All Spectrum Illumination Series Back Lights are built using Modular Board Technology (MBT). Because we use MBT we are able to make back lights in 1" (25.4mm) by 2" (50.8mm) incremental dimensions. The reason MBT is important is that when the boards are assembled in the housing, the LED spacing is the same on a single board as it is from board to board. The result of MBT is even illumination over the length and width of the light (connecting the lights together creates dead spots between lights because LED spacing is not observed). Every light is designed in a heavy duty industrial enclosure. Every Standard Series Back Light is built with 12 surface mount LEDs per square inch so they produce bright even illumination. Standard Series Back Lights run on industry standard 24 volt DC power. Standard Series Back Lights also incorporate a high speed low current sourcing input for strobing the lights directly from a vision sensor or PLC output. The strobe line can be tied directly to 24 volt DC so the light remains on constant. All Standard Series Back Lights use industry standard 4 pin M12 Eurofast quick disconnect cables and are supplied with a 4 meter mating cable.

Linear Lights

LL - Monster Series
Spectrum Illumination Monster Series Linear Lights are used for both bright field and dark field illumination. Monster Series Linear Lights are built using Modular Board Technology (MBT). The reason that MBT is important is that when the boards are assembled in the housing, the LED spacing is the same on a single board as it is from board to board. The result of MBT is even illumination over the length of the light (connecting lights together create dead spots between lights because LED spacing is not observed). The Monster Series Linear Light was designed to be used for applications requiring a large area of coverage and/or a long working distance. Typically they are used in applications that demand a lot of light and can be mounted 12" (304.8mm) to 20' (6,096mm) from the desired area of interest. LED optics and diffuser options are also available on these lights that make it possible to obtain closer working distances and/or larger coverage areas. Every light is designed in a heavy duty industrial enclosure. Monster Series Linear Lights can be purchased in standard lengths starting at 2" (50.8mm) up to 80.5" (2,044.7mm) with longer lengths available upon request. Monster Linear Lights are supplied with our DIN rail mount 24 volt DC High Speed LDM (LED Driver Module) Adapter and a 4 meter 5 pin reverse keyed M12 Eurofast quick disconnect cable. The LDM Adapter has both PNP and NPN strobe inputs with a 3 microsecond response time and is also available with an optional variable potentiometer control or 0-10VDC analogue control.

Linear Lights

Monster Series Linear Light High Power Option

Monster Linear Lights are also available in a high output version (call for model part number). These Linear Lights are the brightest in the Machine Vision Industry. These lights are the standard for several prominent theme parks and they are used to replace Xenon Strobes for computer image manipulation. This version is housed in a heat sink extrusion and is protected against over-temperature with an automatic thermal overload cutout. This model can run continuous but we recommend a 50% duty cycle to extend the life of the LEDs.

Controllers

In 2001 at Spectrum Illumination we identified the need for a current regulating LED Driver to run High Flux LEDs for the Machine Vision Industry. At that time we didn’t see any cost affective, stable or reliable options available. We realised that the future of Machine Vision Lighting would move towards High Flux LEDs if a solution was available. Our engineering staff started development on the first current regulating driver specifically designed to run High Flux LEDs for the Machine Vision Industry. The challenges that we faced during the design involved making the unit compact, affordable, repeatable and reliable. Our feeling was that the unit needed to employ industry standard DIN rail mounting and because electrical panel space is a premium the unit needed to be compact. We also felt that the unit needed to be included with our lights as a package without adding significant cost to the end user. The driver also needed to be repeatable so that every time the unit was pulsed the current output did not change even on demanding high speed applications. The final and maybe most important thing was that the driver needed to be reliable so that it would outlast the LED light. The LDM Adapter was released in 2002 meeting all the standards that we had set out to achieve. Since the LDM’s release, significant advances in efficiency and strobe response time have been improved. We have since released the ALDM (analogue) Adapter for users requiring intensity changes via analogue control and our VLDM (variable) Adapter for manual control via potentiometer. The ALDM and VLDM Adapters are designed based on the proven LDM Adapter platform. The latest release (Revision H) was designed to integrate directly with our Ethernet based Monster Brain Controller (MBC). Advanced communication, pulse timing and intensity control can be achieved utilising the MBC Ethernet controller. Our Controllers are simply the best High Flux LED drivers in the Machine Vision Industry.

Dome Lights

DL - Monster Series Dome Lights
Spectrum Illumination Monster Series Dome Lights are the largest standard product dome lights in the Machine Vision Lighting Market. We have standard sizes up to 29.25" (743mm) diameter. Monster Dome Lights leverage our Monster LEDs to provide the most light possible for your image acquisition needs. Dome Lights are used to create even lighting on shiny or uneven surfaces. Dome Lights are built using a molded fibreglass hemisphere to reflect multi angle light onto the field of view. Because the light is coming from multiple angles, the image from a shiny or uneven surface will not have any hotspots or shadows. Every light is designed in a heavy duty industrial enclosure. Monster Dome Lights can also be used with Monster Diffused Axial Lights to eliminate the appearance of the camera viewing port of the dome on mirrored surfaces. The Monster Dome Lights are supplied with our DIN rail mount 24 volt DC High Speed LDM (LED Driver Module) Adapter and a 4 meter 5 pin reverse keyed M12 Eurofast quick disconnect cable. The LDM Adapter has both PNP and NPN strobe inputs with a 3 microsecond response time and is also available with an optional variable potentiometer control or 0-10VDC analogue control.

Tripod Modular Light System

TP1 - Series
The Tripod's unique triangular design makes it possible for the end user to configure the lights to meet their specific needs. Each Tripod Module incorporates the latest high output LED technology available including our internal Micro Driver with burst. The Tripod Modules can be used separately as a spot light or they can be used together to create single, double or multiple row linear lights. They can also be used to create large area lights, ring lights or rectangular ring lights. If the end user needs a light in the shape of an "L", "U" or "S", that is no problem for the Tripod. Every Tripod Module can be configured as the Master or Slave. Up to 50 modules can be run on a master. The end user can decide if all of the modules need to be strobed together or separately. They can also decide if they would like to control the analogue signal intensity all together or separately. Tripod modules are also set to burst the LED for 500 microseconds at the maximum current rating when initially triggered and then drop down to normal run current. The end user also has the choice to turn the burst circuit off if desired.
