摘要:
An exit sign comprising a housing, a plurality of green color LEDs and red color LEDs or bicolor green and red color LEDs positioned in the housing for emitting both a green color light and a red color light with a filter holder for holding a selected green color filter or a selected red color filter for passing the selected green color light or selected red color light to a stencil having openings for passing the selected green color light or selected red color light to an observer. Yellow color LEDs can be alternatively positioned in the housing for emitting yellow color light comprising both green color light and red color light. White color LEDs can also be alternatively positioned in the housing for emitting white color light also comprising both green color light and red color light.

An elongate tubular lighting assembly having a body with a length between spaced first and second ends. The tubular lighting assembly has a source of illumination and first and second connectors respectively at the first and second body ends. The first connector has cooperating first and second parts having first and second surfaces. The first and second connector parts are configured so that the first and second surfaces are placed in confronting relationship to prevent separation of the first and second connector parts with the body in an operative state as an incident of the first connector part moving relative to the second connector part from a position fully separated from the second connector part in a substantially straight path that is transverse to the length of the body into an engaged position.

An apparatus and a method are provided for a smart modular illumination system configured to orient and illuminate a plurality of illumination nodes toward a moving object within a target area. The system comprises a controller that signals the illumination nodes when a motion detector observes movement within the target area. The controller refrains from signaling the illumination nodes when ambient light within the target area exceeds a predetermined value. An adjustable mounting member coupled with each of the illumination nodes orients the illumination nodes according to signals received from the controller. The smart modular illumination system is configured to adjust the orientation and brightness of all of the illumination nodes so as to cast light on the moving object from a variety of angles with a reduced occurrence of shadows.

An illuminating device includes a connecting portion supplied with power, a conversion circuit that converts power supplied from the connecting portion, a case having a tubular shape, a support body that divides the case in the radial direction, and a plurality of light emitting diodes provided on one surface of the support body. The illuminating device further includes a drive circuit that drives the light emitting diodes, a secondary battery provided on the other surface of the support body, a charge/discharge control circuit for the secondary battery, and a control section that lights the light emitting diodes by supplied power and charges the secondary battery. The control section permits lighting of the light emitting diodes by a discharge of the secondary battery in a state in which power supply is stopped.
摘要:
A multiple function LED night light has at least one LED device and added function(s) such as an air-freshener adaptor device, sonic device, frequency device, sensor device, bug repeller device, second light device, timepiece, electric message device, timer device, temperature device, surge protection device, electric short circuit protection device, base device for installation on an existing lamp socket, emergency light device, or any other electric device(s) suitable for home use to keep people comfortable or safe. The LED device has a first optic means to change the narrow-viewing angle of an LED's spot-light beams into a wider-viewing angle and second optic means to help make the LED night light exhibit a smooth lighting effect. The device may be arranged to fit into an existing night light bulb socket to turn any existing bulb night light into a power saving LED night light.

A low voltage LED bulb having a base that fits a standard light socket designed to receive a bulb operated at line voltage is installed in a conventional lamp, which is connected by a lamp cord to a rechargeable battery, the charge in which is maintained by a charging circuit. The rechargeable battery can be provided in a module equipped with a receptacle capable of receiving a standard plug designed for line voltage, and in this case, the lamp requires no modification other than the replacement of the standard bulb by the low voltage LED bulb. In another embodiment, the battery and charger are incorporated into the lamp.
摘要:
A device having built-in digital data means is powered by an unlimited power source for a lamp-holder, LED bulb, or light device connected to unlimited power source by prongs or a base that can be inserted into a socket that would otherwise receiving a bulb. The device may take the form of a webcam having auto tracking functions and retractable prongs that plug directly into a wall outlet.
摘要:
A direct troffer-style fixture for solid state light sources and pan structures for use in these fixtures. The fixture comprises a door frame assembly that is attached to the pan. The pan housing is defined by a base and two angled side walls. End caps are attached to the side walls. End reflectors extend at an angle away from the end caps and attach to the base. The end caps, the end reflectors, and the base define compartments at both ends of the housing in which components can be housed. A light board is attached to the base using alignment holes in the base and cutout portions of the end reflectors. The multifunctional end reflectors retain elements within the compartments, provide added structural stability to the pan, aid in aligning a light board, and they reflect light that impinges on them toward the open end of the fixture.
