Lamp-level lighting control (LLLC), also known as embedded control, is a lighting control system. By installing sensors and controllers in luminaires to control and manage lights, it increases the flexibility and convenience of lighting management and greatly improves energy efficiency.

DLC Defines LLLC As:

The ability to install networked occupancy sensors and ambient light sensors in each luminaire or kit, and directly integrated or embedded into the form factor during the luminaire or kit manufacturing process.

Simply put, LLLCs combine LEDs, controls, connectivity, and data to create flexible lighting systems.

LLLC System Components

1. Sensors

Sensors include occupancy sensors, light sensors, or both.

2. Controllers

Controllers contain programmable microprocessors and can be an integral part of the LED driver or a separate device that sends dimming signals to the driver.

3. Wireless or wired connections.

Wireless connections are achieved through onboard radio transmitters and receivers that connect the luminaire to the LLLC network.

In addition, depending on the system, network hardware and software may be added on top of the LLLC luminaire. The hardware may include a hub or gateway and a central server (or cloud platform). Hubs and gateways act as central collection points to manage data flow in a network. A central server (or cloud platform) stores data. Users can view data or remotely control devices through it.

Efficient Lighting

Lamp-level lighting control (LLLC) further reduces the energy consumption of lamps through application control, achieving energy saving. Through various lighting control solutions, users can customize lighting systems to maximize energy utilization while also improving comfort. LLLC is a trend in future commercial lighting.
