An illumination device includes a reception portion configured to receive a terminal ID stored by a radio terminal; a transmission portion configured to transmit the received terminal ID and a device ID; an illumination portion configured to emit light from a light source; and a housing portion configured to be detachably provided to the illumination portion and include a secondary battery capable of supplying power to the reception portion and the transmission portion.

An emergency LED lighting system maintains power to an LED lighting source based on measured voltages and currents provided to the LED lighting source; rolls back or decreases power provided to an LED lighting source over time in order to increase the amount of time the battery can power the LED lighting source; executes a soft start procedure, such that the power provided to the LED lighting source is gradually ramped up during activation of the LED lighting sources; identifies a type of battery coupled to the emergency LED lighting system; cycles the emergency LED lighting system between charging mode and standby mode to reduce power consumption over a window of time; detects AC power or an absence of AC power; and/or uses a status LED to communicate information about the emergency LED lighting system with a remote device.

A lamp assembly including a front cover, a lens assembly, a light-emitting assembly, and a rear cover. The front cover and the rear cover are connected to each other to form a cavity, and the lens assembly and the light-emitting assembly are disposed in the cavity. The front cover includes a first chamber. The first chamber runs through the front cover and the lens assembly is disposed in the first chamber. The lens assembly includes a rotation trough and at least one lens. The rotation trough includes an end face, a second chamber, and an opening, and the at least one lens is disposed in the second chamber. The opening of the rotation trough is disposed towards the light-emitting assembly. A transparent plate is connected to the end face, and one end of the at least one lens is connected to the transparent plate.

An LED light fixture includes a housing, a controller circuit having direct current (DC) and alternating-current (AC) power inputs, a direct-current (DC) power supply unit (PSU) connected to the controller circuit, an alternating-current (AC) PSU connected to the controller circuit, and at least two groups of light emitting diodes (LEDs) operable to emit light, wherein each group includes at least one LED of a first type and at least one LED of a second type. In some embodiments, when the LED light fixture operates in a security mode the controller prevents power from flowing to the AC PSU and allows power to flow to the DC PSU to power only the first type of LEDs of the at least two groups of LEDs to emit a security light.

A luminaire includes a housing with a single piece, monolithic body, and a circuit board coupled to the housing. The circuit board includes circuitry for connection of lighting elements thereto, and is connectable to an external controller. An external controller controls lighting functions of the luminaire over a low voltage power and data connection.

An emergency sign with orientable light assemblies is an apparatus that displays a message or instructions and alerts nearby individuals of an emergency or event. The apparatus includes a sign, a first orientable light assembly, and a second orientable light assembly. The first orientable light assembly and the second orientable light assembly each include a brace, a post, a sleeve, a carriage, a track, and a light fixture. The first orientable light assembly and the second orientable light are mounted onto the sign and are opposite each other about the sign. The brace positions the light fixture about the sign. The sleeve integrated into the brace and the post is rotatably connected within the sleeve so that the light fixture may spin. The carriage is terminally mounted to the post and the track is integrated into the light fixture so that the light fixture may laterally slide.
