A housing is located at least partially beneath a rest shelf of a T-bar or other support for ceiling tiles. A spine extends up from the rest shelf. The housing includes an opening with a centerline which extends at least partially laterally. A light source such as an LED within a recess of the housing shines out of the opening along the centerline in an at least partially lateral direction. A diffuser is preferably provided spanning this opening. The housing preferably includes a front wall opposite a rear wall, with the rear wall larger than the front wall and with the opening in the housing extending between lower portions of the rear wall and lower portions of the front wall. Heat transfer fins on an upper surface of the rest shelf and upper end of the spine are preferably provided to assist in heat dissipation.

The T-bar includes an elongate rigid spine extending between terminal ends including either a fixed anchor or adjustable anchor for attachment to adjacent T-bars or other supports. An upper heat sink is provided on an upper portion of the spine to enhance heat transfer from the T-bar to air surrounding upper portions of the T-bar. A light housing is provided on a lower portion of the T-bar which is configured to support a lighting module therein, such as a light emitting diode (LED) light. A lower heat sink is provided above this light housing and integrated into a rest shelf which supports ceiling tiles adjacent the T-bar. A power supply is provided which can be removably attached to the T-bar and provide appropriately conditioned power for the lighting module.

The present invention provides a ventilating and illuminating apparatus. The ventilating and illuminating apparatus includes a ventilating fan, a connecting frame, an illuminating device and a connecting shaft. The ventilating fan has a housing. The connecting frame is connected to the housing and has a mounting portion and a fastening hole. The fastening hole is disposed on the mounting portion. The illuminating device has an illuminating element and a through hole. The connecting shaft partially passes through the through hole of the illuminating device and the fastening hole of the connecting frame and is mounted on the mounting portion of the connecting frame, so as to fasten the illuminating device on the mounting portion of the connecting frame.

A combination fan and light unit comprises a housing surrounding a coaxial fan disposed such that air impelled by the fan passes through the housing and is directed as desired by orienting the housing or by diffusers disposed across the air path. Disposed above and/or below the housing, a light optionally enclosed within a globe coupled to the housing also provides illumination from the fan light unit. Fan light units may be arrayed in various configurations, including single or multiple sconce arrays supported on walls, one or more pendant fan lights suspended from ceilings, satellite fan lights arrayed around a central body at the ends of radial arms to form a fan chandelier or in many other configurations to achieve both aesthetic lighting and directed air flow. The fan lights preferably have separate controls, and multiple units in a collective array such as a fan chandelier may be individually or collectively controllable. The fan light units may include heater strips to warm the air and filters to clean the air as it passes through the air handler.
