Abstract
A self-contained luminaire, driver, and attachment assembly has at least a first luminaire, an attachment beam defining a driver receiving cavity, and a driver assembly configured to fit within the driver receiving cavity. The first luminaire includes a single row of light emitting diodes, and at least a first set of optics that is configured to provide a horizontal spread and a vertical spread of at least a portion of light emitted from the single row of light emitting diodes. The vertical spread of light is bounced off a reflective visor.
Claims32
A self-contained luminaire, driver, and attachment assembly comprising:
- at least a first luminaire;
- an attachment beam defining a driver receiving cavity;
- and
- a driver assembly configured to fit within the driver receiving cavity;
- wherein the first luminaire comprises a single row of light emitting diodes, and at least a first set of optics that is configured to provide a horizontal spread and a vertical spread of at least a portion of light emitted from the single row of light emitting diodes.
A LED luminaire comprising:
- a rear fixture plate with a heat sink connected to the rear fixture plate;
- a LED board configured to connect to the rear fixture plate;
- at least a first optics holder,
- at least a first optics member configured to be held adjacent the LED board by the first optics holder;
- a window, and
- a front frame configured to trap the window, the first optics member, the first optics holder, and LED board adjacent the rear fixture plate;
- wherein the LED board includes a single row of LEDs and the heat sink includes a predetermined number of heat sink fins, the LED board includes a predetermined number of LEDs, and a ratio of the predetermined number of LEDs to the predetermined number of heat sink fins ranges from 2.0 to 3.0.
An optics member comprising:
- a center plate portion;
- a forward lens portion defining an upper undulating boundary and a lower undulating boundary;
- and
- a rearward LED receiving portion including a plurality of cones each defining an elongated cavity;
- wherein the forward lens portion is angled away from the center plate portion to redirect light upward relative to the plurality of cones.
The optics member of claim 28, wherein the acute angle ranges from 9.0 degrees to 11.0 degrees. 29a. The optics member of claim 29, wherein the acute angle is about 10.0 degrees +/−0.25 degrees.
