LED Light Engine With Segmented Thermal Management

The patent divides the LED array into multiple independently controllable groups or strings, where each group contains a subset of LEDs that can be controlled separately. This segmentation allows the system to achieve desired total lumen output by activating multiple groups while maintaining manageable complexity within each group, as each can be controlled independently through separate control circuits.

The patent implements dynamic control capabilities where the illumination intensity of different LED groups can be adjusted independently in real-time. This allows the system to optimize lumen output by selectively activating or dimming specific groups based on lighting requirements, thereby achieving high overall illumination while managing the complexity of individual groups through adaptive control strategies.

The patent divides the LED system into multiple separate groups that can be independently managed and positioned. This segmentation allows for distributed thermal management where heat from each group can be handled separately, making it easier to adapt to existing fluorescent encasement structures without requiring a single large heat sink, thereby maintaining adaptability while addressing thermal concerns.

The patent introduces separate control circuits and potentially thermal management intermediaries between the LED groups and the encasement structure. These intermediaries facilitate the integration into existing fluorescent fixtures by providing interfaces for both electrical control and thermal management, allowing adaptability to legacy encasements while managing the thermal characteristics of LED arrays.

The patent divides the LED array into multiple groups with separate control circuits, where each group has its own return path. This segmentation enables independent control of each group through simple binary control signals (on/off or dimming levels), making operation easy despite the segmented structure. The control system can address each group independently using straightforward control logic.

The patent implements control circuits that can selectively activate subsets of LED groups based on lighting requirements. Rather than controlling all LEDs uniformly, the system can activate only the necessary groups to achieve desired illumination levels, simplifying operation by allowing partial activation of the total LED array while the underlying circuit structure remains manageable through modular design.
