LED Filament Reflector Layout for Color Mixing and Low Spottiness

The reflector is segmented into multiple sections along the LED filament, with some sections having openings and others being enclosed. This segmentation allows different portions of the LED light to be treated differently - some for color temperature control via reflection, others for direct emission to maintain aesthetic appearance and prevent spottiness.

Different sections of the reflector have different properties - some sections are enclosed to control color temperature, while other sections have openings to allow direct light emission. This local differentiation resolves the contradiction by applying the appropriate structure in the appropriate location along the filament.

The reflector is divided into multiple sections with varying degrees of enclosure. This segmentation enables light mixing in enclosed sections while allowing direct emission through openings in other sections, thereby preventing spottiness while maintaining aesthetic appearance.

Instead of fully enclosing the encapsulant, the reflector provides partial enclosure through multiple sections. This partial action is sufficient to achieve light mixing while avoiding the harmful effect of complete enclosure, which would cause spottiness and aesthetic degradation.

The reflector serves multiple functions: it controls color temperature, manages light mixing, and maintains aesthetic appearance through its segmented structure with openings. This multi-functionality eliminates the need for separate components for each function, reducing overall device complexity.

The reflector and encapsulant structures are merged into an integrated design where the reflector's segmented configuration directly controls light emission characteristics. This merging reduces the number of separate components needed while achieving effective color temperature control.
