(26) In some embodiments, the sliding track 665 has a segmenting structure for the external housing to move along the sliding groove segment by segment.

(27) Please see FIG. 16. For example, the exterior housing has an elastic block 672 which is held by a segmenting structure, e.g. a jagged structure 671, for keeping the movement of the exterior housing with respect to the sliding track in a segment by segment manner.

(28) In some embodiments, the sliding groove has multiple segment positions for the protruding block to move and stay in one of the multiple segment positions. This may be implemented similarly as the sliding track with the example in FIG. 16. But other designs may also be used for providing such segmented movement.

(29) In some embodiments, the sliding track is a circular track.

(30) In some embodiments, the sliding track has a stop structure 6614 to limit a rotation angle of the exterior housing 664 with respect to the sliding track 665. The exterior housing may have a hinge 6615 stopped by the stop structure 6614 when the rotation angle is over a limiting angle, e.g. 180 degrees.

(31) In some embodiments, the light source module has a lens 6617 for guiding a light direction of the light.

(32) In some embodiments, the lens 6617 is manually moved to adjust a relative distance between the lens and the LED module 662 to change a beam angle of the light.
