Omron / Sentech FLV-DR9030 Direct Ring Light

FLV-DR9030

The FLV-DR9030 is part of Omron's FLV-DR Series of high-density LED direct ring lights, with a 90 mm external ring diameter, a 40 mm internal ring diameter, an 84 mm emitting-surface diameter and a 30-degree (medium) lighting angle. It is offered in multiple wavelengths: white (FLV-DR9030W, 8.1 W), red (FLV-DR9030R, 6.6 W, ~635 nm), blue (FLV-DR9030B, 8.1 W, ~460-465 nm), infrared (FLV-DR9030IR, 4.3 W, ~850 nm) and ultraviolet (FLV-DR9030UV, 6.8 W, ~385 nm; the UV variant has a 94 mm outer diameter and 220 g weight). The light unit uses an aluminum-alloy case with an 0.8 m lead cable and is powered through an Omron FLV-series lighting controller (e.g. FLV-TCC or FLV-ATC). An optional diffusion plate (FLV-DR9030DF / FLV-DR9000DF) is available for more uniform illumination, and as part of the FLV series it carries an IP20 rating and a 0 to +50 deg C operating temperature range.

Technical overview

The Omron FLV-DR9030 is a direct ring light, meaning its high-density LEDs sit in a 90 mm outer / 40 mm inner ring and project light forward toward the part along the camera's optical axis. The defining optical choice here is the 30-degree (medium) emission angle: the LEDs are aimed inward rather than straight down, so the beams from the 84 mm emitting surface converge onto the work at a moderate incline. That geometry is the workhorse setting for direct illumination - bright enough to flood a textured or matte surface with even, frontal light, yet angled enough to start raising contrast on engraving, embossing, surface texture and printed marks. With the camera looking down through the 40 mm central aperture, the ring delivers shadow-reduced, broadly uniform illumination that suits the product's stated work: defect and surface inspection, OCR/OCV, printed-code traceability and packaging checks.

Wavelength is a key lever on this family, and the FLV-DR9030 is offered across the full FLV-DR palette so the same ring geometry can be tuned to the target. White (this variant, 8.1 W) is the general-purpose choice for color and broadband mono inspection; red (~635 nm, 6.6 W) maximizes contrast and sensor response on monochrome cameras and is a strong default for code reading; blue (~460-465 nm, 8.1 W) tightens contrast on fine surface detail; IR (~850 nm, 4.3 W) can suppress color-only print to isolate structural detail; and UV (~385 nm, 6.8 W) is the band for fluorescence-based tasks such as adhesive, coating and security-mark verification. Choosing the wavelength is choosing the contrast mechanism - pick the band that makes your defect or mark brightest against its background, and pair it with a matching bandpass filter on the lens if ambient light is a concern. Note the UV unit is physically larger (94 mm outer dia., 220 g) than the 200 g W/R/B/IR units.

Two integration facts shape how this light is designed in. First, it does not drive itself: the FLV-DR9030 is powered through an Omron FLV-series lighting controller (FLV-TCC or FLV-ATC), reached over its 0.8 m lead cable, so the controller is what handles power and intensity for the ring. Budget that controller into the bill of materials and panel space. Second, the environmental envelope is modest: an IP20 rating and a 0 to +50 deg C operating range mean this is a clean-environment, in-enclosure or guarded-station light, not a washdown unit. The aluminum-alloy case handles LED heat and gives a rigid M90 body with four M3 mounting holes for repeatable fixturing, and an optional diffusion plate (FLV-DR9030DF family, including DF30/DF50) can be added when the bare direct beam is too harsh and a softer, more uniform field is needed on glossy or specular parts.

Best for

  • Frontal, shadow-reduced inspection of matte and textured surfaces where the camera looks down through the 40 mm central aperture - surface and defect inspection on electronics, automotive and printed parts
  • OCR/OCV and printed-code reading on packaging and labels, using the red (~635 nm) variant on a mono camera for high contrast
  • Print and packaging quality checks where the 84 mm emitting surface gives even coverage of small-to-mid-size parts and the 30-degree angle lifts contrast on embossed or engraved marks
  • UV fluorescence tasks (FLV-DR9030UV, ~385 nm) such as verifying adhesive beads, coatings or security inks that glow under near-UV excitation
  • IR-band inspection (FLV-DR9030IR, ~850 nm) to suppress color print and reveal structural detail independent of ink color

Selection notes

  • Plan for a controller: the FLV-DR9030 has no onboard driver and must be powered through an Omron FLV-series lighting controller (FLV-TCC or FLV-ATC), which sets power and intensity - budget that into the bill of materials and panel space
  • Match the wavelength to the contrast mechanism, not by default - white (8.1 W) for color/broadband, red ~635 nm (6.6 W) for mono code/contrast, blue ~460-465 nm (8.1 W) for fine detail, IR ~850 nm (4.3 W) to ignore ink color, UV ~385 nm (6.8 W) for fluorescence; note the UV unit is physically larger (94 mm outer dia., 220 g vs. 200 g) and slightly different to fixture
  • The 30-degree medium angle and 84 mm emitting surface define the bright zone - size your field of view and working distance so the part sits within that even-illumination footprint, and verify the camera lens clears the 40 mm inner aperture
  • IP20 and a 0 to +50 deg C range limit this to clean, dry, climate-controlled stations - it is not rated for washdown, dust-heavy or hot environments without additional enclosure protection
  • If parts are glossy or specular and the bare direct beam produces hotspots, plan for the optional FLV-DR9030DF diffusion plate (DF30/DF50 options) to soften and homogenize the field; mounting uses the M90 body with four M3 holes and an 0.8 m lead cable, so confirm cable reach to the controller
