Abstract: A rotating flashing warning signal lamp is disclosed to include a housing houses a LED type light source, a reflector, which has an anchoring member for positioning, a flat reflecting panel for reflecting light from the LED type light source, and a friction hinge coupled between the flat reflecting panel and the anchoring member for allowing adjustment of the reflecting angle of the flat reflecting panel, and a power drive, which has a driven member that supports the anchoring member of the reflector, a motor, and a driving member driven by the motor to rotate the driven member, thereby turning the reflector about the LED type light source to produce a flashing warning signal when the LED type light source is turned on.

Abstract: A LED lamp is disclosed to include two LEDs arranged opposite to each other on a bracket and electrically connected to an electric connector connectable to an external power source, and a lens shell covering the LEDs. The lens shell has vertical prism ribs spaced around the inside wall and horizontal prism teeth extending around the outside wall at different elevations and respectively sloping in one direction at a respective angle to enhance the light field during operation of the LEDs.
