DCM Sistemes ALB1716B Direct High-Powered Ring Light

ALB1716B

The ALB1716B is the largest model in DCM Sistemes' ALB series of direct high-powered ringlights, measuring 168x168x38.5 mm with a 76 mm inner diameter and rated IP65, and delivers far more light than the ALD series to illuminate objects from greater distances while highlighting textures and contours. It integrates iBlueDrive technology supporting continuous, strobe and powered (overdrive) operation, runs from 24 VDC via a 3-pin Type C aerial male connector, and is available in multiple wavelengths (365 nm UV, 400 nm UV, 470 nm blue, 525 nm green, 630 nm red, 850/880 nm IR, white and RGB). Maximum instantaneous Type C consumption ranges from 10 W (IR) to 22 W (400 nm) depending on wavelength, with 17 W for white and 20 W for blue/red. The anodized-aluminium housing operates from 0 to 40 degrees C and is offered with narrow, medium (default), wide, oval and diffuse emission angles plus optional polarizer and diffuser filters.

Technical overview

The ALB1716B is the largest member of DCM Sistemes' ALB series of direct high-powered ring lights, an annular illuminator that emits from a Ø76 mm inner to Ø168 mm outer ring across a 168 x 168 x 38.5 mm anodized-aluminium body. As a direct ring, the LEDs sit on the same axis as the camera and project light forward onto the scene rather than diffusing it, so the geometry produces bright, fairly even frontal illumination that rakes across surface texture and contour. DCM specifies it as a high-output unit that delivers far more light than the lower-power ALD series, which is what lets it illuminate non-reflective objects from a greater recommended working distance (RWD >50 mm) while still pulling out detail. The camera lens looks through the 76 mm central aperture, so the part-to-light spacing and the inner-diameter clearance govern how much of the field is evenly lit and where specular hot-spots fall.

Wavelength is the key design lever here, and this single model is offered across a wide menu: 365 nm and 400 nm UV, 470 nm blue, 525 nm green, 630 nm red, 850/880 nm IR, white, and RGB. Each choice changes what the light reveals — short wavelengths (UV/blue) raise contrast on fine surface defects and fluorescing materials, red and IR penetrate or suppress certain materials and sit at or beyond the edge of the visible band for ambient-immune setups, and white serves general-purpose colour imaging. Maximum instantaneous draw on the Type C connector tracks the LED choice: roughly 10 W for IR at the low end, 17 W for white, 20 W for blue/red, and up to 22 W for the 400 nm UV version, all from a 24 VDC supply (+24 V ±8%). The emission angle is selectable too — medium is the default (/AM), with narrow (/AN), wide (/AW), oval (/AO) and diffuse (/AD) variants — so the same ring can be tuned to a tight bright spot or a broader, softer wash depending on part size and standoff.

Electrically and mechanically the ALB1716B is built to drop into a line with minimal external hardware. Its standout feature is the integrated iBlueDrive driver: the high-power LED driver is built into the light itself, so no separate strobe controller box is required, and the unit supports continuous, strobe, and powered (overdrive) operation directly. Power and control arrive on a single 3-pin Type C aerial male connector (L=150 mm) wired PIN1 +24 V, PIN2 0 V, PIN3 control, which is what carries the trigger for strobe/overdrive timing. The housing is rated IP65 (with an IP67 option) for washdown and dusty environments, operates from 0 to 40 °C, and weighs 940 g — a substantial unit that needs a planned mechanical mount. Optional polarizer and diffuser (/FDR) filters round out the package for glare control and softening when the application calls for it.

Best for

  • Frontal surface and defect inspection of larger, non-reflective parts where a high-output ring is needed to reveal texture, scratches, dents and contour from a standoff of more than 50 mm
  • UV/blue fluorescence and fine-defect contrast tasks using the 365 nm or 400 nm UV (up to 22 W) or 470 nm blue options, where short-wavelength raking light exposes flaws hard to see under white light
  • Ambient-immune or material-specific imaging in red (630 nm) or IR (850/880 nm), e.g. suppressing background colour or working under variable factory lighting in electronics and automotive lines
  • AI-based defect inspection and OCR/OCV reading on printed, embossed or coded surfaces, where strong, angled annular light maximises character and mark contrast
  • Washdown or dusty installations (packaging, metal, automotive) that require an IP65/IP67-rated, fanless light with no external controller box to mount

Selection notes

  • Confirm the wavelength at order time — this is a single model offered in 365/400 nm UV, 470 nm blue, 525 nm green, 630 nm red, 850/880 nm IR, white or RGB; the choice is fixed per unit and drives both the contrast you get and the power draw (10 W IR up to 22 W for 400 nm UV).
  • Budget the 24 VDC supply for the worst-case instantaneous draw of your chosen wavelength, and note that strobe and powered (overdrive) modes via iBlueDrive demand current in pulses — size the 24 V rail (+24 V ±8%) and wiring on the 3-pin Type C connector accordingly.
  • Plan the mechanical mount and optics around the geometry: the camera must look through the Ø76 mm inner aperture, the outer ring is Ø168 mm, and the unit is 38.5 mm thick and weighs 940 g, so it needs a rigid bracket and clearance for the 150 mm aerial cable.
  • Pick the emission angle to match part size and standoff — default medium (/AM), narrow (/AN) for a concentrated spot, wide (/AW) for larger fields, oval (/AO) for elongated parts, or diffuse (/AD) to soften the light; the RWD >50 mm is a recommendation, so validate evenness at your actual working distance.
  • Because this is a direct (not diffuse) ring, glints on any glossy areas are possible; the optional polarizer reduces specular glare and the diffuser filter (/FDR) or /AD diffuse variant softens output if your part has reflective regions despite being predominantly non-reflective.
