BS-TUN
Bestshow
Built for real-world tunnels—not just catalog photos—the LED Tunnel Light delivers consistent roadway luminance, controlled glare, and dependable uptime. The die-cast aluminum body feels solid to the touch; the tempered glass has a quiet heaviness you notice the second it clicks into the latch. When traffic roars, the luminaire stays silent: no rattle, no flicker, just a steady white beam that flattens shadows and keeps drivers calm through the transition.
Where legacy HPS washed out color, this luminaire restores contrast so road markings read cleaner and objects “pop” earlier in a driver’s peripheral vision. Add the adjustable bracket and you can fine-tune the aiming angle during commissioning—micro-adjustments you hear as a soft metal scrape, then lock-down confidence.

Underpasses & long tunnels: stable luminance and reduced disability glare help maintain driver comfort through day-night adaptation zones.
Retrofit from HPS: up to double-digit energy and maintenance savings via higher efficacy and long L70 life; fewer closures for relamping.
Industrial portals & service corridors: dust-tight IP66 with robust glass shields against impact and airborne particulate.
Municipal budgets: predictable TCO through standardized drivers (Meanwell/Sosen) and universal voltage.
Visual clarity: neutral/cool whites (4000K/5000–6500K) heighten object contrast versus legacy amber sources.
Distribution thinking: select optics to support counter-beam, long-narrow, or cross-beam layouts; combine angles with bracket tilt for wall- or ceiling-mounted grids.
Uniformity & glare: higher on-pavement uniformity improves recognition distances; tempered glass contributes to visual comfort; flicker-free drivers protect camera/ANPR performance.
Documentation: IES files available on request; support for layout assistance to hit target average luminance and uniformity ratios per project spec.

Driver & input: AC85–265V; PF ≥0.9; THD-conscious design with Meanwell/Sosen options.
LED engine: SMD3030, 100–130 lm/W typical system efficacy.
Protection: IP66 dust/water ingress protection; explosion-proof tempered glass resists debris impact.
Thermal path: full-aluminum heatsink pulls heat away from LEDs and driver, stabilizing lumen output during summer peaks.
Lifecycle: long operational life reduces lane-closure events for maintenance, protecting traffic throughput.
Adjustable bracket (180°) enables precise tilt for counter-beam patterns; lockable fasteners keep aim through vibration.
Multi-surface mounting: wall, ceiling, or ground; suitable for cross-beam wall rows in narrow underpasses.
Serviceability: surface you can wipe clean; tempered glass resists micro-scratches; driver access designed for fast swaps.
Commissioning tips
Start with bracket preset per design calc, then field-aim ±2–5° to fine-tune luminance on pavement.
Stagger circuits to enable staged dimming during off-peak hours.
Dimming: driver-level dimming ready; supports scheduling or sensor-based reductions overnight.
Zoning: entrance/threshold/interior/exit zones can be grouped for gradient lighting to mitigate “black-hole” effect.
Add-on: occupancy/daylight sensing and networked control gateways available upon request (project-based).
Ingress: IP66
Materials: aluminum housing + explosion-proof tempered glass lens
Standards: CE / EMC / LVD / RoHS；SAA / SASO as required by market
Quality: flicker-free driver architecture for safety-critical environments
(Additional regional listings can be aligned per tender requirements.)
CCT options from 2700–7000K enable environment-specific tuning; 3000K reduces scatter in fog-prone regions; 4000–5000K balances acuity and comfort.
Glass lens survives routine jet-wash and airborne grit; seals maintain performance in dust and spray conditions.
Thermal headroom keeps electronics within comfort zones during summer heat events.
Highways & city underpasses: the light lands evenly, so lane markings look crisp; the hum of traffic is the only sound.
Logistics portals: white light tracks forklift paths without banding in CCTV footage.
Transit hubs: cleaner color rendering aids signage legibility and traveler wayfinding.
Design-to-commissioning support: from photometric layouts to bracket aiming guides, we stay in the loop until the hand-off.
Supply assurance: mainstream driver brands (Meanwell/Sosen) for global availability and predictable spares.
Field-proven mechanics: robust aluminum build and explosion-proof tempered glass minimize breakage and down-time.
Flexible CCT & power: 50–600W with broad CCT, making retrofits straightforward across mixed tunnel segments.
Q1: What wattage should I select for an HPS retrofit?
Match target pavement luminance and spacing rather than nameplate watts. Provide us mounting height, spacing, and target cd/m²—we’ll return a layout with recommended wattage and optic.
Q2: How do you control glare at the entrance zone?
We combine appropriate distribution with bracket tilt and step-down dimming from threshold to interior, keeping adaptation smooth.
Q3: Can I wall-mount for cross-beam layouts in narrow underpasses?
Yes. The adjustable bracket supports wall mounting; we’ll provide aiming angles and spacing.
Q4: What about maintenance windows?
Long service life and robust glazing reduce interventions; driver access is straightforward when swaps are needed.
Q5: Do you support networked control platforms?
Project-based integrations are available. Share protocol and zoning needs with the RFQ.
