Abstract:
The multiple function LED project light is a hand-held and powered by DC power, and the project light has front lens has project magnify lens fit-into or install-on or built-in on center position. The project lens has below position outer-tube set assembled together so outer-tube can envelope or surrounded the lower position separated inner-tube which has image-forming unit within. While the project head move away from the project light neck by screw-thread or other extend construction to make distance between the magnify lens and image forming-unit changed to get focus adjustment functions. The said Project light may has self-prong, or project light fit within the hold-base which has prong-set both get AC current through the AC-to-DC circuit to get desired DC power for LED or SMD-LEDs or Dip-LEDs or COB-LED or other DC operated electric components to use. The said project light at least have project image function and flashlight functions or-and other more different functions light select from market available types.
