ROTATABLE LIGHTING APPARATUS
First Claim
1. A rotatable lighting apparatus, comprising:
- a terminal;
a base, wherein the terminal is fixed on the base, an end of the base opposite to the terminal forms a junction portion, and the junction portion includes at least one protruding part;
a rotatable lamp holder, pivoted at the junction portion of the base and comprising;
a heat dissipation part, comprising a plurality of restricting trenches for fastening to the protruding part; and
a lighting source, fixed on a single face of the heat dissipation part;
a passing-through device, passing through the base and the rotatable lamp holder, and the rotatable lamp holder is able to move relatively to the passing-through device along a moving-axis; and
a bellow device, connected to the base and the rotatable lamp holder, when a tensile force is applied to the rotatable lamp holder, the rotatable lamp holder is capable of moving relative to the base along the moving-axis, so that the protruding device is departed from the corresponding restricting trench, and thus the rotatable lamp holder is capable of rotating relative to the base, when the tensile force is removed, the rotatable lamp holder is fastened to one of the restricting trenches by resilience of the bellow device, so that the rotatable lamp holder is fixed on the base.

Abstract
A rotatable lighting apparatus includes a terminal, a base which includes a protruding part at a junction portion thereof, a rotatable lamp holder pivoted at the base and including a heat dissipation part and a lighting source, a passing-through device passing through the base and the rotatable lamp holder, and a bellow device connected to the base and the rotatable lamp holder. The heat dissipation part has a plurality of restricting trenches for fastening to the protruding part. When a tensile force is applied to the rotatable lamp holder, the rotatable lamp holder is capable of moving relative to the base along a moving-axis, so that the rotatable lamp holder is capable of rotating relative to the base. When the tensile force is removed, the rotatable lamp holder is fastened to one of the restricting trenches, so that the rotatable lamp holder is fixed to the base.

5. A rotatable lighting apparatus, comprising:
-
a terminal; a base, wherein the terminal is fixed on the base, an end of the base opposite to the terminal comprises a protruding portion, and an outer wall of the protruding portion comprises at least one locking protruding ring; a rotatable lamp holder, pivoted at the protruding portion of the base and comprising; a heat dissipation part, comprising a receding part for housing the protruding portion, a circumference of the receding part comprises at least one locking receding ring for fastening to the locking protruding ring; and a lighting source, fixed on a single face of the heat dissipation part; wherein after the locking receding ring is fastened to the locking protruding ring, the rotatable lamp holder only has one degree of rotational freedom relative to the axis of the base, and the angles of the rotational freedom exceeds 360 degrees. - View Dependent Claims (6, 7, 8, 9)
