Abstract

An energy efficient lighting fixture includes a light emitting diode section, a first high intensity fluorescent section having a first bulb and provided adjacent the light emitting diode section, and a second high intensity fluorescent section having a second bulb and provided adjacent the light emitting diode section. The fixture also includes a first reflector partially surrounding the first bulb and a second reflector partially surrounding the second bulb.

Claims

1. An energy efficient lighting fixture comprising:

a light emitting diode section;

a first high intensity fluorescent section having a first bulb and provided adjacent the light emitting diode section;

a second high intensity fluorescent section having a second bulb and provided adjacent the light emitting diode section; and

a first reflector partially surrounding the first bulb and a second reflector partially surrounding the second bulb.

2. The fixture of claim 1, wherein the first bulb is positioned on a first side of the light emitting diode section and the second bulb is positioned on a second side of the light emitting diode section.

3. The fixture of claim 1, wherein the first reflector is shaped to direct light in a first direction from a first side of the fixture and the second reflector is shaped to direct light in a second direction from a second side of the fixture.

4. The fixture of claim 3, wherein the first reflector includes a curved surface having a profile that extends at least 180 degrees around a centerline of the first bulb and the second reflector includes a curved surface having a profile that extends at least 180 degrees around a centerline of the second bulb.

5. The fixture of claim 1, wherein the light emitting diode section is coupled to a surface of a support member provided intermediate the first and second bulbs.

6. The fixture of claim 5, wherein the first reflector includes a wall positioned above the surface of the support member.

7. The fixture of claim 6, wherein the first reflector includes a curved portion extending generally outward from an upper edge of the wall, around an upper surface of the first bulb, and downward to a point below the first bulb such that light of the first bulb is prevented from escaping upwards relative to the fixture when the fixture is mounted in position.

8. The fixture of claim 1, further comprising a controller configured to operate the light emitting diode section independently of the first and second high intensity fluorescent sections.

9. The fixture of claim 1, further including a sensor configured to detect movement in an area proximate the fixture.

10. The fixture of claim 9, wherein the light emitting diode section and the first and second high intensity fluorescent sections are configured to light in different manners based on the type of motion detected.

11. A method for efficiently lighting an area comprising:

providing a lighting fixture that comprises

a light emitting diode section;

a first high intensity fluorescent section having a first bulb and provided adjacent the light emitting diode section;

a second high intensity fluorescent section having a second bulb and provided adjacent the light emitting diode section; and

processing electronics configured to cause the lighting fixture to provide increasing levels of illumination in response to state changes associated with sensed motion, wherein the state changes comprise;

(a) a transition from a no-motion state to an initial motion state;

(b) a transition from the initial motion state to a sustained motion state; and

(c) a transition from the sustained motion state to a lingering motion state.

12. The method of claim 11, further comprising providing a first reflector partially surrounding the first bulb and a second reflector partially surrounding the second bulb.

13. The method of claim 11, further comprising:

sending or receiving signals to the processing electronics from a motion sensor; and
