Indoor Parking Lighting Control

Anticipatory Luminance Propagation (ALP)

When one fixture detects a vehicle or pedestrian, it signals the fixtures around it over a 5.8 GHz link. The path ahead is lit before anyone reaches it.

See the Difference

Light that leads, not follows.

Conventional sensors react only once you are under the fixture. ALP signals ahead, so drivers and pedestrians see each other early.

Conventional occupancy sensors

P2 · Drive aisle B

Each fixture reacts only once you are under it. The aisle ahead stays dark.

ALP networked lighting

P2 · Drive aisle B

The detecting fixture signals ahead. Drivers and pedestrians see each other early.

Conventional with a pedestrian

P2 · Walkway

Each fixture reacts only once the walker is under it. Someone waiting ahead stays in the dark until the walker is close.

ALP with a pedestrian

P2 · Walkway

A person on foot triggers the same signal. The path ahead lights as they walk to their car, including around each turn.

Dark zones ahead of a car are where a pedestrian goes unseen, most of all when the car turns into an aisle that is still dark. More important, they are where someone can wait out of sight. Lighting the path ahead lets a person walking to their car see who is there before they get close.

How ALP works.

01

Detect

A vehicle or pedestrian enters a fixture's zone.

02

Signal

The fixture broadcasts to nearby fixtures at 5.8 GHz.

03

Brighten Ahead

The path is lit before arrival.

04

Dim Back

Fixtures return to standby once the zone clears.

Why It Is Safer

Sightlines open before people meet.

Conventional

Light follows the occupant.

A driver rounding a column sees a pedestrian only when both are already in the lit zone.

ALP

Light leads the occupant.

Approach paths are lit in advance, so drivers and pedestrians see each other early.

Why It Costs Less

One unit. Nothing extra to install.

No Sensors to Install

Detection is built into every fixture. There are no separate sensors to mount, wire to run or node to commission.

Service Is a Simple Swap

Sensing, control and light are one unit. If the light is on, it is working. If a fixture goes bad, replace it.

Priced Like a Sensor

ALP is a module that integrates with the fixture's power supply, priced comparably to current occupancy sensors.
