The utility model discloses a rotatable LED
arc lamp of adjusting
irradiation direction relates to LED
arc lamp technical field, include: lens
face shield, PCB board, lamp house, adjusting cylinder, mounting support, supplementary positioning mechanism includes small
laser diode lamp, the outer wall of PCB board is installed with
diode magnetic attraction board, the outer wall of
diode magnetic attraction board is installed with
laser diode lamp. The utility model discloses through being installed with supplementary positioning mechanism, installs diode magnetic attraction board and
laser diode lamp in the position close to
light source, and with
irradiation direction parallel, then carries out electric connection to
laser diode lamp, when needing to adjust angle, can utilize switch control to make
laser diode lamp light up and emit
light beam, LED
arc lamp emits light, then staff can emit
light beam through
laser diode lamp at this time, judges the position of the target that needs to irradiate, can, improves the adjustment efficiency and accuracy.
