An LED lighting ball structure includes a spherical shell, a control unit and a plurality of LED lighting units. The silicon nitride hard masks include carbon-doped silicon nitride layers and undoped silicon nitride layers. Connecting groups of n rows of the contacts to n\u22121 rows of vias disposed interstitially between the contacts, thereby forming a horizontal channel that does not extend completely through the contact array, and intersects with the vertical channel. The aperture sizes of the diaphragm at outside the specified range are used at least for one of the following: automatic exposure adjustment, auto focus adjustment, electronic zoom, displaying a moving image, taking for recording the moving image, and taking under a low resolution by thinning out pixels. Power conversion is facilitated by one or more input supply power feeds and one or more converter stages. An eccentric drive assembly is connected between the output shaft and a platform and has components treated with a corrosion inhibiting coating.
