Abstract: A strip of encapsulated linear lighting with a partially encapsulated electrical connector is disclosed, as are processes for manufacturing such strips of encapsulated linear lighting. In these processes, connecting structure is connected to a strip of linear lighting. A portion of the connecting structure is then sheathed in a stopper. The stopper is used to dam a vessel or channel, the dammed vessel or channel is filled with resin, and the resin is caused or allowed to cure. The stopper protects the connecting structure from resin during the encapsulation process and leaves its contacts unencapsulated and exposed. The connecting structure can be connected to external structures, like a power cable or another segment of encapsulated linear lighting, after manufacture. A joint between the connecting structure and another structure can be overmolded or otherwise protected.

Abstract: The combined color of a color tunable and intensity adjustable light source can be quantitatively described using the chromaticity diagram. With a preset color, or dominant wavelength, and daily light interval, the microprocessor in this plant growing system can compare the calculated chromaticity diagram data from the corresponding sensor with this preset color value and fine tune the combined color until these two are matched. The microprocessor then can control the lighting time according to daily light interval setting. The system can then automatically control the color and photon numbers. The same control method and algorithm can be used in general lighting system as well.
