Abstract
A vibration resistant, energy efficient lamp () that is suitable for, for example, ceiling fan operation where vibration is always a concern. The lamp () comprises an envelope () of a suitable transparent glass, for example, a borosilicate glass, having a substantially spherical upper body () with a given diameter D, a substantially cylindrical waist () having a diameter W of about 38% of the given diameter; a neck portion () having a diameter N of about 31 to about 32% of the given diameter and a threaded base () having a diameter B of about 25 to 27% of the given diameter. The base () has a skirt portion () adjacent the neck portion having diameter S substantially equal to the neck portion () diameter N and larger than the diameter B of the base (). The skirt () provides a broader attachment area for the neck (), thus strengthening the coupling and providing a stronger joint that is more suited to operations in those functions where vibration can be encountered, especially in those areas where the lamp is mounted base-up.
