Our philosophy

High technology, made simple

D-SLS — Digital Smart Lighting Solutions — designs and manufactures premium luminaires whose intelligence serves everyone: from municipalities to industry, from engineers to field technicians, from large design offices to clients with no experience of connected lighting. Our belief is simple: an exceptional product must never be complicated to install, control or maintain.

A word from the founder

Our reason for being

AS
Atmani SalahFounder and technical director, D-SLS
A premium luminaire must not be reserved for experts. It must be beautiful, simple to install, simple to repair, and intelligent from day one — no engineering, no licence, no dependency.

D-SLS was born from a simple observation: cities want quality light and digital tools, but they run into closed, costly and complex systems that demand rare skills and force their data to be opened up to the outside. We chose the opposite path.

Each of our products is designed to be digital and natively communicating: luminaires talk to each other, to market drivers and to the city, with no additional hardware or prior engineering study. Our management platform comes free with the equipment and can run entirely locally, inside the municipality's network.

What sets us apart

Six design principles

Accessible to everyone

Our products speak to all: the municipality cutting its bill, the engineer demanding EN 13201 compliance, the technician swapping a luminaire in five minutes, and the client discovering smart lighting. High technology without the barrier of complexity.

Installation without engineering

No design office needed to deploy. Our luminaires fit every existing bracket and pole, connect in a few gestures, and configure without specialised software. The city lights up, the installer reinvents nothing.

Local management, no imposed cloud

Many municipalities refuse to let their data leave their territory. Our platform runs locally, free of charge, with no dependence on an external cloud. You stay owner of your network and your data — sovereignty is not an option, it's the foundation.

Maintenance in five minutes

We design for repair, not replacement. One part clips onto the bracket with a connector: the technician opens the luminaire, swaps the module in under five minutes, without dismantling the whole unit. The faulty part returns under warranty, the light never goes out.

One controller, the whole city

Where others aim LiDAR at automotive, drones or aviation, we dedicated it to public lighting. Our single controller unites the technologies that exist — Zhaga Book 18, DALI D4i, TALQ 2.7.1, PWM, 0–10 V — to drive an entire city, whatever drivers are already in place. One brain, every luminaire.

Quality of light, not just lumens

On the LOTUS luxury luminaire we developed a switch-on that rises gently with presence, for comfort and perceived light quality — not the raw glare from a PMMA lens. Care in the reflector, the shape of the housing, elegant mechanics: the beautiful and the right, together.

The heart of our technology

MPPT-ATMANI-AI — one product, all the technology

Where the industry multiplies boxes — a solar regulator here, a driver there, a management node elsewhere — we brought everything together in a single controller. The MPPT-ATMANI-AI concentrates all the technologies and options into one product, designed for public lighting end to end.

Smart solar harvestingBidirectional 18–58 V MPPT with V2G re-injection: the controller scans the PV panel, diagnoses its soiling and ageing, and optimises harvesting continuously.
Active-balancing BMSBattery management by energy transfer — no wasteful passive dissipation. State of charge and health telemetered, for maximum storage lifetime.
Multi-chemistry batteryOne controller for every technology: supercapacitors, LiFePO4 and other chemistries. The same electronics adapt to the storage chosen for the site.
Adaptable Zhaga 18/20 commsZhaga Book 18 and 20 receptacle, DALI D4i, TALQ 2.7.1: the same protocols as our grid luminaires. A solar unit that speaks exactly the same language as the rest of the city.
Integrated LED driverMPPT, BMS, driver and gateway in a single IP66 aluminium housing — less wiring, fewer failure points, simpler maintenance.
Cybersecurity & anti-theftEncrypted VPN, signed updates, GPS and accelerometer: real-time alert and remote disabling in case of theft.
One platform, two worlds

Manage solar AND grid, together

Our LidarMesh platform does not separate the worlds: it supervises autonomous solar points and grid-connected points in the same interface. A municipality can drive its mixed network — solar on the outskirts, grid in the centre — from a single dashboard, with the same controller everywhere. Solar stops being a system apart: it becomes a brick of the same smart network.

  • Solar points and grid points in the same platform
  • Supervision of charge, battery and autonomy per point
  • Integrated weather forecast — anticipating critical nights
  • Solar vs grid energy balance, accounted separately

End-to-end mastery

We design the whole chain

From the LED chip to the firmware, from optics to the management platform, everything is conceived and developed in-house. This vertical integration is what lets us guarantee the consistency, quality and simplicity of a complete system — where others assemble bricks from different suppliers.

From LED to software, all designed in-house

D-SLS designs, industrialises and deploys complete smart public-lighting solutions. The entire chain — optics, mechanics, electronic board, firmware, management software — is developed in-house. That is what lets us guarantee product consistency and evolve a network throughout its lifetime.

Our commitment

Light right, for everyone

D-SLS exists so public light becomes a measurable, frugal and lasting service — accessible to the small town as to the great metropolis. We carry high technology all the way to the field, without ever making it out of reach. That, to us, is smart lighting.
