Grid-Powered Smart Park & Pedestrian Street Lighting System with Motion-Adaptive CMS Control

Overview

The RC-PSL-300 is a grid-powered, pedestrian-scale smart lighting system purpose-built for urban parks, public plazas, waterfront promenades, university and corporate campuses, and pedestrian-only shopping streets. Unlike main-road street lighting (designed for 8-12 m mounting heights and vehicle traffic) or off-grid solar pole systems (sized around battery autonomy), the RC-PSL-300 is optimised for human-scale visual comfort at 3-6 m mounting height, decorative architectural styling, and continuous AC mains operation — the natural fit for sites that already have a buried grid distribution loop and where solar panels would be aesthetically intrusive or simply unnecessary. REDCOAST.LTD designs the entire signal chain in-house: the constant-current LED driver, the single-lamp CMS control node, the PIR motion-sensing front-end, and the protective enclosure are all on custom PCBs that we can re-spin per project for power class, dimming protocol, regional certification and connectivity stack.

Key Features

• Pedestrian-scale decorative pole portfolio: traditional lantern, modern cylinder, square heritage and minimalist cone styles, 3 m / 4 m / 5 m / 6 m mounting heights.
• High-efficacy 20-80 W LED luminaire with REDCOAST.LTD-designed constant-current driver, 0-10 V / DALI / PWM dimming, up to 150 lm/W.
• Single-lamp CMS control node integrated in the luminaire or in a NEMA / Zhaga D4i socket, with per-pole power metering, fault diagnostics and group control.
• PIR / microwave hybrid presence detection enabling adaptive dimming (e.g. 30 % standby, 100 % on detection), reducing energy use by 40-70 % in low-traffic hours.
• AC 100-240 V wide-input mains design with 10 kV / 10 kA surge protection, suitable for unstable grids and lightning-prone regions.
• Modular smart-pole sockets supporting optional 1080p AI CCTV, Wi-Fi 6 access point, IP-65 horn speaker, environmental sensors and USB-C public charging.
• Connectivity choice: PLC over the lighting grid, LoRaWAN mesh, NB-IoT, or 4G / Wi-Fi 6 backhaul — selectable per project.
• IP66 luminaire and IK10 vandal-resistant lens, designed for coastal, tropical and dusty environments.
• Smooth matte powder-coated or fluorocarbon-painted pole finish in RAL 7016 anthracite, RAL 9010 white, RAL 9005 black or custom colour — engineered, not raw galvanized.
• Web CMS and mobile app for scheduling, dimming, alarms, energy reporting and integration into city-level IoT platforms via MQTT / REST / NTCIP 1213.

Technical Architecture

At the heart of every pole sits the REDCOAST.LTD-designed driver-controller PCB. The constant-current LED stage delivers 350-1050 mA programmable output with <10 % THD and >0.95 power factor, isolated to IEC 61347 Class II. A dedicated MCU running our hardened firmware handles dimming, scheduling, brown-out recovery and per-lamp telemetry; it talks to the single-lamp control node over an internal bus that mirrors the NEMA D4i / Zhaga D4i specification, so third-party nodes can also be used when project standards require it.

The presence-detection sub-board fuses a PIR sensor with an optional 5.8 GHz microwave radar to distinguish pedestrians from wind-moved foliage, reducing false triggers that traditional PIR-only luminaires suffer in landscaped parks. Detection events drive a dimming profile configurable per zone — for example, 30 % baseline on quiet park paths between 23:00-05:00, ramping to 100 % within 0.5 s on pedestrian approach, then fading back over a tunable hold time.

At the city level, every pole publishes its state (energy, voltage, current, temperature, lumen output estimate, sensor events) to the REDCOAST.LTD CMS through PLC, LoRaWAN, NB-IoT or 4G. The CMS supports group scheduling, astro-clock based dusk-to-dawn operation, dynamic scenes for festivals and events, fault tickets and OPEX reporting. Open northbound APIs (MQTT, REST, NTCIP 1213) allow integration with smart-city platforms, asset-management systems and SCADA.

Connectivity & Power

Power is exclusively grid-based: AC 100-240 V, 50 / 60 Hz, single phase per pole, fed from a buried distribution loop, a kiosk transformer or an existing park lighting circuit. Each pole draws 20-80 W at the luminaire plus up to 60 W for optional smart modules, with built-in surge and over-current protection so the upstream MCB can be sized at 10-16 A per group. Because the load is grid-connected and continuous, no solar panel, battery or MPPT charge controller is installed — keeping the silhouette clean and avoiding the maintenance burden of battery replacement in landscaped public spaces.

For connectivity, the default option is power-line communication (PLC) over the lighting feeder, which means no extra cabling and reliable mesh coverage along the park loop. LoRaWAN is offered where a city gateway already exists. NB-IoT or 4G LTE Cat 1 / Cat M is used for isolated installations or where the project owner prefers a cellular SLA. Wi-Fi 6 backhaul is available when the optional Wi-Fi AP module is installed, allowing both public hotspot service and CMS backhaul over the same radio.

Protection & Reliability

Every luminaire is rated IP66 against jetting water and IK10 against impact — important for public spaces where vandalism and high-pressure cleaning are routine. The driver enclosure is sealed with a silicone gasket and breathing membrane to prevent condensation. The pole base door is lockable with a triangular or Allen-key system to deter tampering. All exposed steel is hot-dip galvanised internally and then finished externally with a smooth matte powder coat or fluorocarbon paint in the specified RAL colour, giving 25+ years of corrosion resistance in C4 / C5 environments including coastal and industrial sites. The luminaire is rated for -30 °C to +60 °C ambient operation, 0-95 % humidity non-condensing, and a 5 % salt spray test per ISO 9227 for marine deployments. LED L80B10 lifetime is 100,000 hours at Ta=25 °C; the driver carries a 5-year warranty and the luminaire a 7-year warranty.

Application Scenarios

• Urban public parks: Decorative lantern-style RC-PSL-300 poles along walking paths, jogging tracks and lakeside promenades, with PIR-driven dimming to save 50-70 % energy in low-traffic hours while keeping the park safe and inviting.
• City pedestrian shopping streets: Modern cylinder poles with white finish and warm 3000 K light, optional festive-RGB ring for seasonal scenes; integrated Wi-Fi 6 and public USB-C charging draw shoppers and dwell time.
• University and corporate campuses: 4-5 m square heritage poles with integrated AI CCTV for safety, IP speaker for evacuation announcements and environmental sensors feeding a campus dashboard.
• Waterfront and coastal promenades: Anti-corrosion C5-M finish, IP66 luminaire and salt-spray-tested driver electronics for seafront boulevards and marina promenades.
• Heritage and historic districts: Replica gas-lantern styling on top of a fully digital LED + CMS platform — the visual identity of the district is preserved while operations are modernised.
• Plazas, civic squares and event venues: Dynamic scene control for ceremonies, concerts and national-day lighting, programmed centrally from the CMS.

Case-style Examples

• City Central Park Upgrade — Grid-Powered Decorative Retrofit: A 14-hectare city park replaces 280 ageing HPS lanterns with 4 m RC-PSL-300 traditional-lantern poles, RAL 7016 anthracite finish, 40 W warm-white LED, PLC backhaul. The retrofit reuses existing cable trenches and the original distribution kiosks. Measured energy consumption drops 62 % year-on-year, and the CMS auto-generates a monthly carbon-saving report for the city sustainability office.
• Pedestrian Shopping Street with Public Wi-Fi and CCTV: A 1.2 km pedestrian commercial street installs 96 poles of 5 m modern cylinder design, 60 W luminaires at 4000 K, with optional Wi-Fi 6 AP and 4 MP AI CCTV on every fourth pole. The local authority gets a unified dashboard for footfall, dwell heatmaps and incident alerts; retailers benefit from sustained evening foot traffic.
• Coastal Boardwalk on a Tropical Island: A 2 km seafront promenade chooses 5 m poles with C5-M anti-corrosion finish, IP66 luminaires, 4000 K cool-white optics, salt-spray-tested PCB conformal coating and 4G LTE backhaul. The CMS schedules astronomical dusk-to-dawn lighting and a 30 % overnight dim from 00:00 to 05:00, while reporting any luminaire fault within 30 seconds.

Customization & Selection Guide

Projects should first define the visual brief (heritage, modern, minimalist, themed) — REDCOAST.LTD can match pole style to this brief, including custom castings and laser-cut decorative bands. Next, define the mounting height based on path width and intended illuminance class (EN 13201 P3-P6 is typical for pedestrian areas), and select luminaire wattage accordingly: 20-30 W for 3 m intimate paths, 40-50 W for 4 m main walkways, 60-80 W for 5-6 m plazas and wider promenades. Choose colour temperature with care: 2700 K for heritage districts and parks where low blue light is required by local environmental rules, 3000 K for commercial pedestrian streets, 4000 K for safety-critical campus and transit interchange use. Finally, decide on smart modules upfront, even if installed in a later phase — the pole and CMS will be pre-wired so retrofit is plug-and-play.

Deployment & After-sales

The RC-PSL-300 is delivered as a complete system: foundation cage, pole, luminaire, driver, control node, optional smart modules, CMS license and mobile app. Civil works (foundations, trenching, cabling) follow a project drawing pack we provide. On-site we offer commissioning support, CMS training and an as-built handover. Each pole carries a unique QR code linking to its digital twin in the CMS, simplifying maintenance dispatch. Standard production lead time is 30-45 days for typical project quantities. Spare parts (driver modules, control nodes, sensor sub-boards) are stocked for 10 years. Warranty: 5 years on driver and control electronics, 7 years on the LED luminaire, 25 years on the pole structure.

Why REDCOAST.LTD

REDCOAST.LTD is a one-team integrator of smart outdoor IoT systems delivering hardware, web management platform and mobile app as a single end-to-end solution. Because we design our own PCBs — the constant-current driver, the single-lamp control node, the PIR / microwave front-end — we can re-spin them per project: a different dimming protocol for one country, a different surge-protection class for another, a different connectivity stack for a third. We do not bolt third-party drivers into a generic housing; we own the schematic, the firmware, the CMS and the app, which means faster response on field issues, cleaner integration and a roadmap you can influence as a customer.

Contact our project team to share your site brief — pedestrian flow, environmental class, target illuminance, decorative style, smart-module scope — and we will return a tailored RC-PSL-300 configuration, photometric simulation, BoM and lead-time within five working days.
