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.

A lighting assembly includes a lighting tower. The lighting tower includes a plurality of layers of lighting elements, where each layer of lighting elements is configured to provide a different angle of emitted light onto a parabolic reflector with respect to light emitted from another layer of lighting elements onto the parabolic reflector when activated.

A lighting device is disclosed operating a vivid source having a first duty cycle and a dulling source with second duty cycle. The vivid source and the dulling source operate at alternating time intervals where the intensity of one wavelength segment or block is emphasized in the vivid source and absent or de-emphasized in the dulling source. The operation provides the user with an emphasis on objects that reflect or absorb the emphasized wavelength segment.

In some embodiments, a configurable lighting device, connectors, controllers, and methods for layout detection are provided. The configurable lighting devices, suitably connected, form an assembly of configurable lighting devices that can be removably connected with one another and re-arranged. Connectors are provided that form mechanical and electrical connections between configurable lighting devices such that a flow of electricity and control signals may be propagated without the need for direct connection between every configurable lighting device and a controller. The controller or devices connected to the controller are configured to perform layout detection such that pleasing visualizations may be rendered across the assembly that are rendered using at least the detected layout. When the configuration of the configurable lighting devices changes, the layout detection is automatically updated.

A combination axial fan and LED lighting system. The system includes a housing container and an axial fan. The fan has a fan cavity including air diversion mechanism to direct air from the fan cavity toward the lighting and fan components. The invention includes an airflow surface to direct air existing the fan cavity along an LED light fixture. The invention includes a vented mechanical equipment casing configured to include an opening to direct a portion of the air exiting the fan cavity into an equipment chamber housing the mechanical equipment and configured to direct the air to encounter the mechanical equipment and operate to reduce the temperature of the equipment.

A luminaire includes a support positioned in a ceiling. A light module is connected to the support having a base, a light emitter, and an optic. The light modules allow different luminaire configurations to be formed out of similar components.

A sorting system including a plurality of sorter light boxes, a hub, and a controller. The plurality of sorter light boxes may each be configured to be mounted to a respective shelf, and may each configured to be coupled to another one of the sorter light boxes to create a chain of sorter light boxes. The hub may be configured to be coupled to a first sorter light box in the chain of sorter light boxes. The hub may also be configured to operate as a concentrator of control signals and power for the sorter light boxes. The controller may be configured to be coupled to the hub and may be configured generate control signals for the sorter light boxes.

The customizable item sorting system is configured to guide a sorter to sort items to match specific orders for a shipper to ship. The system includes sorter light boxes to be customizably positioned at a respective shelf, and each configured to be coupled in a chain of sorter light boxes. A plurality of shipper light boxes are each configured to be coupled to a respective sorter light box and also positioned at the respective shelf. A hub is coupled to a first sorter light box in the chain and operates as a concentrator of control signals and power for the plurality of sorter light boxes in the chain. A power supply is configured to be coupled to the hub and supply power to the sorter light boxes and shipper light boxes. A controller is configured to be coupled to the hub and generate the control signals for the sorter light boxes in the chain of sorter light boxes based upon commands received via an externally coupled network, and a repeater is configured to be coupled within the chain to push power along the chain.
