With the continuous iteration and upgrade of smart lighting systems, the increasingly refined management of lighting material inventory, and the increasing diversity of lighting applications in scenarios such as dimming, color temperature adjustment, and focus adjustment, market requirements for light source performance are undergoing profound changes. In response to this trend, dimmable and color-adjustable COB lighting solutions, due to their adaptability and flexibility, have become a mainstream choice in the industry in recent years and are highly favored by the market. Based on this, Luminus has a precise understanding of demand and continuously invested in technical optimization and functional upgrades for several of its dimmable and color-adjustable COB products to provide solutions that better suit current lighting applications and meet market and customer needs.

This article primarily focuses on single- and dual-channel mass production solutions; COB solutions with three or more channels will be covered separately.

Product Portfolio Single-channel and dual-channel solutions (with both checkerboard and stripe options available)

Single-channel Solution

1.1 Application Scenario

Single-channel dimming solutions are currently primarily deployed in high-end hotels and restaurants, aiming to replicate the color temperature variation of traditional halogen lamps during dimming. End users generally expect LED light sources to fully replicate the visual experience of the gradual color temperature drift of halogen lamps.

1.2 Core Technology

Luminus’ proprietary IC driver architecture synchronizes current changes with color temperature (CCT) adjustment, precisely matching the dimming curve of halogen lamps. Furthermore, a multi-strip grading design optimizes secondary optics to address uneven light output.

1.3 Product Specifications

• LES 6mm9mm14mm
• Color temperature range 1800K–2700K, 1800K–3000K, 2000K–3000K
• Note For linear light mixing requirements, the above specifications also offer linear dimming curve versions for customer selection.

Dual-channel Solution

2.1 Application Environments

Hotel Lighting A high CRI and high light mixing checkerboard solution creates a more realistic lighting environment. It also supports intelligent dimming from 2700K–6500K, suitable for various environments such as lobbies, corridors, and bedrooms, enhancing the comfort and sense of luxury.

Museum Lighting Developed across the full power range and offering a comprehensive solution, it ensures consistent lighting for both accent lighting and general scene lighting. A modular optical solution achieves uniform light distribution, adapting to changing environmental requirements. Home Lighting Soft, even light distribution and the ability to integrate smart modules create a versatile lighting environment, laying the foundation for satisfying villa and home lighting needs.

Commercial Lighting Track lights and downlights, ubiquitous in stores and shopping malls, can be equipped with a dialer for multi-level dimming and color adjustment, greatly improving convenience and effectively reducing lighting inventory.

2.2 Checkerboard Solution

The dual-channel checkerboard COB covers a variety of light-emitting surface sizes 6mm, 9mm, 12mm, and 14mm, and offers differentiated solder pad designs to accommodate customers’ diverse packaging and wiring requirements. Simultaneously, a full-spectrum, high-CRI solution was launched, providing diverse options for different application environments and meeting diverse lighting needs.

2.3 Strip Solution

The dual-channel strip COB covers a variety of light-emitting surface sizes 6mm, 9mm, 14mm, 18mm, and 22mm, with a full range of power and color temperatures.

Product Advantages

• Diagonal and square solder pad options available
• Simple bracket design, standard baseplate size
• Full power range development, variable color temperature range
• Both checkerboard and stripe layouts available
