A dual LED and incandescent security lighting system uses a hybrid approach to LED illumination. It combines an ambient LED illuminator with a standard incandescent lamp on a motion control sensor. The LED illuminator will activate with the onset of darkness (daylight control) and typically remain on during the course of the night (“always on”). The LED illumination, typically amber, is sufficient to provide low to moderate level lighting coverage to the wall and ground area adjacent to and under the fixture. The incandescent lamp is integrated with a motion control circuit and sensor. When movement in the field of view is detected (after darkness), the incandescent lamp is switched on, providing an increased level of illumination to the area. Instead of an “always on” LED illuminator, the LEDs may also be switched off when the incandescent lamp is switched on.

A coaxial illuminated laser endoscopic probe and active numerical aperture control apparatus and method of use, succinctly known as an illumination and laser source, capable of selectively providing illumination light and laser treatment light through a single optical fiber. The apparatus and method is especially useful during ophthalmic surgery. The present art is capable of providing the aforesaid through an optical fiber of such small size that heretofore said fiber was only useable for laser treatment light only. The present art also, with its unique optical system, allows for two illumination light outputs from a single illumination source. The apparatus utilizes a phototoxicity risk card to calibrate the system to prior art or safe illumination levels since the unique optical system provides illumination light of greater intensity than the prior art.

The present invention transforms existing electrical wall outlets into an emergency lighting system for homes, hospitals, hotels, nursing homes and businesses. The lighting device, designed as a replacement electrical wall outlet or receptacle, simply plugs into an existing dual outlet after removal of its faceplate. The lighting device continues to function as an electrical outlet, however, also comprises a local power source such as a constant charge lithium ion battery; a motion sensor for initiating a low level of lighting for darkened room or corridor transit; a power sensor for activating a high level of light when electrical service is disrupted, thereby broadcasting a wash of light over an otherwise darkened room or corridor; and a photoelectric cell which detects daylight or otherwise provided lighting of the room or corridor and thereby prevent unnecessary power usage.

A self-contained battery powered high visibility safety lighting system is integrated within portions of a vehicle or article's frame, such as a handlebar or body assembly of a motorcycle, bicycle, scooter or toy cycle, stroller, wheel chair, baby carriage, cane or ski pole. The system comprises at least one illumination segment having at least one light source located therein. The light source may comprise a plurality of light emitting diodes integrated within a plurality of apertures located within each of the illumination segments. In another embodiment the illumination segments may be composed of a transparent material to yield transparent illumination segments with an inlay cavity therein for accommodating an electroluminescent light strip. Light may further be emitted from illuminated streamers located on the handlebar grips. Multifaceted emission of light from illumination segments integrated within the frame of the vehicle is highly visible from virtually all directions. An omnidirectional light-alert increases safety for drivers and others in the vehicle's vicinity.

A lighting strip along the side of a schoolbus or other passenger vehicle between a door near the front of the schoolbus and the back side of the schoolbus to reduce the risk of people or other objects being injured by the schoolbus. The lighting strip may be focused downward to illuminate the ground and may provide vehicle status information and guiding information. Lighting strips may be provided on both sides of the schoolbus, and may also be provided on the back side of the schoolbus and on mirrors or mirror arms. Further, the lighting strips may be provided on the underside of the schoolbus along the passenger side. One or more floodlights may be provided on the roof or near the top of the schoolbus along the side with the door. An expandable crossing gate on the driver's side of the exterior wall is also provided.

A Cycle Wheel Safety Light System uses double-sided shaped A-C electro-luminescent light panels, spaced about the wheels of a bicycle. A DC battery powers the panels via a DC-AC inverter. Alternatively, an alternator mounted between the wheel axle and frame utilizes the bicycle rider's motive power as the source of energy. Another variation combining the best features of both the battery and inverter is use of an alternator to charge (via a rectifier) a smaller battery or other energy storage device such as a 'supercap'. The panels may be of various colors to improve the "WOW!" factor and encourage adolescent use.

A motion sensing system is disclosed having a housing or mounting, a sensor, a shield and a cover. A spacer and a printed circuit board may also be included. The cylindrical shaped sensor is placed within the cup shaped shield with the spacer disposed between the sensor and the printed circuit board. The shield and the printed circuit board are then fastened together. Next, the bottom or nose of the mounting shield is placed into the dish shaped cover and the combination is fastened to the housing with the cover extending into an opening in the bottom wall of the housing. The system allows a downward looking motion sensing capability in addition to the typical forward sensing capability which may also be installed in the housing. The housing may then be connected to a security lighting fixture. An even simpler version is a motion sensing system having a simple mounting for a two transducer PIR sensor where one of the transducers is covered and a Fresnel lens is absent. An effective short range motion detector results and the sensor may be aimed in any direction.
