Nighttime-controlled lighting system
A time-controlled security lighting system records the length of nighttime and is capable of automatically adjusting for seasonal nighttime hours. The time duration between the initial nighttime darkness and the light of dawn, as sensed from the prior day by a photocell, is measured and recorded in memory. As the surrounding area becomes dark, the lighting system is activated to provide the illumination for the area. The duration of illumination is determined based on a predetermined fraction of the recorded length of nighttime from the previous night. The control system can adjust the duration of illumination according the recorded nighttime durations from the previous night. The control system can also adjust the level of illumination based on the signals from a motion detector, where the lights are set at a higher brightness for a predetermined amount of time upon detection of motion.

Dual LED/incandescent security fixture
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.

Coaxial illuminated laser endoscopic probe and active numerical aperture control
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.

A concealed safety light is described where the light source is integrated and mounted into a switch or power outlet wiring device form factor (20,21,22) to replace conventional electric wiring devices. The light source (10) is controlled by a power and control circuit (90, 790) that derives power from the primary power supply or an alternate power supply. The circuit can detect light levels and turn on the light source when it is dark and also detect power failures to turn on the safety light in the event of a power failure using the alternate power supply The safety light is also capable of responding to an alarm condition from other systems. The resulting safety light is conceyaled in a standard wiring junction box and trimmed with a wall cover plate in the same way as conventional electric wiring devices, allowing it to be concealed while in plain view and provide safety lighting in a variety of ways including power failure, night light and alarm conditions.

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.

Photocontrol with radio-controlled timer and a decoder
ActiveUS7345270B1Material analysis by optical meansElectronic switchingTime informationBiological activation
A photocontrol controls the activation of lighting based on ambient light and the time of day using a radio-controlled timer. Radio signals from a particular source of correct time, such as the National Institute for Science and Technology's WWVB radio broadcast, carry encoded time information that can be decoded by the photocontrol to ascertain the current time on start up and periodically during operation. The correct date and time information is used to synchronize the photocontrol's internal clock so that it can turn the lighting load off or on at specific times of the day in accordance with the user's needs. Thus area, business signage, and security lighting, for example, can be turned off late at night and then back on early in the morning to reduce energy consumption by the lighting during those hours when the lighting is not needed.
