Abstract

The integrated laboratory light (lablight) fixture is a sealed ceiling mounted fixture that combines air outlets, lighting and other devices for use in laboratory, clean room, healthcare, educational, and other facilities requiring critical airflow control. The integrated lablight is made for a central location in the lab to eliminate room scale eddies and cross drafts along with the hood challenges they present. The combining of most ceiling devices in one fixture results in a safer environment with greater access for above ceiling maintenance, as well as less expensive facility capital costs. The fixture design also minimizes shadows at the work surface, and promotes temperature stability for temperature sensitive equipment.

Claims

1. A ceiling mounted fixture comprising:

at least one longitudinal arrangement of at least one air vent adapted to receive an air supply; and

at least two longitudinal arrangements of at least one light source, and wherein the at least one longitudinal arrangement of at least one air vent is positioned between the at least two longitudinal arrangements of light sources.

2. The fixture of claim 1, further comprising a duct connection adapted to connect to an airflow source.

3. The fixture of claim 2, further comprising an airflow guide.

4. The fixture of claim 1, wherein the at least one light source comprise a light reflector, a light bulb and a light diffuser or lens.

5. The fixture of claim 1, wherein a ratio of a length of the fixture to a width of the fixture is approximately 2 to 1.

6. The fixture of claim 1, wherein the at least two longitudinal arrangements of light sources comprises at least three longitudinal arrangements of lights sources and at least two longitudinal arrangements of air vents.

7. The fixture of claim 1, further comprising at least one temperature control sensor, which promotes improved temperature stability for temperature sensitive equipment located below the fixture.

8. The fixture of claim 1, wherein the fixture is adapted to be located along a clean room'"'"'s central axis to create a sweeping airflow from center of the lab to the perimeter.

9. The fixture of claim 1, further comprising a linear array of fixtures, wherein the linear array of fixtures enables their alignment in a row along the center of a lab to maximize a room'"'"'s airflow patterns and ambient air mixing.

10. The fixture of claim 1, wherein the fixture can be used in the exhaust mode for rooms with excessive heat generating equipment.

11. The fixture of claim 1, further comprising a perimeter ambient air guide trough promotes the cleanliness of the fixture and lighting lenses by intercepting any room dust or debris due to the aerodynamic design.

12. The fixture of claim 1, further comprising an airflow exit slot designs and exit velocities are designed to deliver low speed, uniform airflow with any potential eddies oriented in the axial direction to minimize eddies in the transverse direction.

13. The fixture of claim 1, further comprising mounting points for room air and supply air temperature sensors, air quality sensors such as CO₂, O₂, VOC and other detectors, optical and acoustic sensors, radiation and other sensors, sprinklerheads, pressure ports, and environmental monitoring devices.

14. The fixture of claim 1, further comprising an electrical connection, wherein the electrical connections for electrical power for the fixture can be connected on the top or the side of the fixture.

15. The fixture of claim 1, wherein the fixture is comprised of material, which is predominantly recycled and recyclable.

16. The fixture of claim 1, wherein the at least one light sources is a fluorescent tube.

17. A fixture comprising:

a central light source;

an air supply duct having a connection point in a center portion of the fixture; and

a flow straightener, wherein the flow straightener routes an air supply through an adjustable flow splitter and around the central light source and out through a series of slots arranged symmetrically perpendicular to an axis of the fixture.

18. The fixture of claim 17, further comprising at least one light source on an outer edge of each of the series of slots arranged symmetrically perpendicular to the axis of the fixture.

19. The fixture of claim 17, further comprising a dark colored lip at a perimeter of the fixture to enhance ambient room air mixing with a supply air stream while providing a concealed area for ambient dust collection.

20. A ceiling mounted fixture system adapted to be located along a lab'"'"'s central axis to create a sweeping airflow from a center portion of the lab to a perimeter thereof comprising:

a plurality of linear fixtures comprising;

a central light source;

an air supply duct having a connection point in a center portion of the fixture; and

a flow straightener, wherein the flow straightener routes an air supply through an adjustable flow splitter and around the central light source and out through a series of slots arranged symmetrically perpendicular to an axis of the fixture; and

wherein the plurality of linear fixtures are aligned in a row along the center portion of the lab to maximize the overall room airflow patterns and ambient air mixing.

21. The system of claim 20, further comprising at least one light source on an outer edge of each of the series of slots arranged symmetrically perpendicular to the axis of the fixture.

22. A ceiling mounted fixture comprising:

at least one longitudinal arrangement of at least one air vent adapted to receive an air supply; and

at least one longitudinal arrangement of at least one light source adjacent to the at least one air vent.

23. The fixture of claim 22, wherein the at least one air vents is comprised of at least two longitudinal arrangements of at least one air vent with at least one longitudinal arrangement of at least one light source between the at least two longitudinal arrangement of at least one air vent.
