## Abstract

A combination for illuminating the interior of a building comprises a fixture and a retrofit kit. The fixture has a base attached to a building ceiling, the fixture having a first tombstone, and a second tombstone. The first and second tombstones are configured to receive between them a fluorescent light tube. The retrofit kit is connected to the base. The retrofit kit includes a light panel, the light panel having a first side facing the fixture and an opposite second side. The light panel resides between the first tombstone and the second tombstone, and the fixture resides above the light panel. The combination is devoid of a fluorescent light tube. The base and the light panel define between them a raceway. A light emitting diode is disposed on the second side of the light panel.

## Claims

### Claim 1

A retrofit kit for mounting with a previously-installed interior ceiling light fixture that has first and second tombstones, the retrofit kit comprising:
a light panel, the light panel having a first end disposed proximate the first tombstone and a second end disposed proximate the second tombstone;
the previously-installed interior ceiling light fixture and the light panel being electrically separated;
a first angled wing, the first angled wing residing on a first side of the light panel and extending:
along the length of the light panel;
outwardly away from the light panel; and
outwardly away from the previously-installed interior ceiling light fixture;
a second angled wing, the first angled wing residing on the opposite second side of the light panel and extending:
along the length of the light panel;
outwardly away from the light panel; and
outwardly away from the previously-installed interior ceiling light fixture; and
a light emitting diode disposed on the second side of the light panel.

### Claim 2 (depends on 1)

The retrofit kit of claim 1, in which the previously-installed interior ceiling light fixture and the light panel define between them a raceway external to the retrofit kit.

### Claim 3 (depends on 1)

The retrofit kit of claim 1, in which the first angled wing and the second angled wing are integral with the light panel.

### Claim 4 (depends on 1)

The retrofit kit of claim 1, in which the first angled wing and the second angled wing are monolithic with the light panel.

### Claim 5 (depends on 1)

The retrofit kit of claim 1, in which the first and second angled wings are light-reflective downward.

### Claim 6 (depends on 1)

The retrofit kit of claim 1, further including a lens having a U-shaped cross-section.

### Claim 7 (depends on 1)

The retrofit kit of claim 1, further including an endcap.

### Claim 8 (depends on 1)

The retrofit kit of claim 1, further including a lens and an endcap, in which the endcap extends from above the light panel to past the bottom of the lens.

### Claim 9 (depends on 1)

The retrofit kit of claim 1, in which the first and second angled wings are both planar and extend downwardly at less than twenty degrees from horizontal.

### Claim 10 (depends on 1)

The retrofit kit of claim 1, in which the first and second angled wings are both planar and extend downwardly at less than fifteen degrees from horizontal.

### Claim 11

A combination, the combination comprising:
a previously-installed light fixture and a retrofit kit;
the previously-installed light fixture including:
first and second electrical receptacles configured to hold a fluorescent light tube but being devoid of a fluorescent light tube; and
a de-energized ballast;
the retrofit kit including:
a light panel, the light panel having a first side facing the previously-installed light fixture and an opposite, planar second side;
first and second light emitting diodes residing on the second side of the light panel; and
an electrical conductor:
electrically separated from the previously-installed light fixture;
in electrical communication with the light emitting diodes;
adapted for electrical communication to a second retrofit kit; and
residing at least in part between the first side of the light panel and the previously-installed light fixture.

### Claim 12 (depends on 11)

The combination of claim 11, in which the light panel resides at least partially between the first and second electrical receptacles.

### Claim 13 (depends on 11)

The combination of claim 11, to which a second retrofit kit has been electrically connected, the two retrofit kits being electrically energized by a single power supply.

### Claim 14 (depends on 11)

The combination of claim 11, in which the first LED emits light of a first color and the second LED emits light of a second color, the first and second colors being different.

### Claim 15 (depends on 11)

The combination of claim 11, further including a lens and an endcap, in which the endcap is in contact with both the light panel and the lens.

### Claim 16 (depends on 11)

The combination of claim 11, in which the previously-installed interior ceiling light fixture and the light panel define between them a raceway external to the retrofit kit.

### Claim 17 (depends on 11)

The combination of claim 11, further including:
a first angled wing integral with the light panel, residing on a first side of the light panel, and extending along the length of the light panel and away from the previously-installed interior ceiling light fixture; and
a second angled wing integral with the light panel, residing on a second side of the light panel opposite the first side, and extending along the length of the light panel and away from the previously-installed interior ceiling light fixture.

### Claim 18

A lighting assembly for mounting with a previously-installed interior ceiling light fixture having first and second electrical receptacles, the lighting assembly comprising:
a first end disposed proximate the first electrical receptacle and a second end disposed proximate the second electrical receptacle;
a light panel;
first and second angled wings integral with the light panel, each extending away from the light panel at a downward angle of less than twenty degrees from horizontal;
a lens, the lens having a U-shaped cross-section;
plural light emitting diodes attached to the light panel, between the light panel and the lens;
endcaps located at the first and second ends; and
the lighting assembly having electrical circuitry independent of the previously-installed interior ceiling light fixture, the electrical circuitry connected with the light emitting diodes and adapted for series electrical connection to a second lighting assembly.

### Claim 19 (depends on 18)

The lighting assembly of claim 18, further including a second lighting assembly, the second lighting assembly and the lighting assembly of claim 18 being powered by a single power supply.

### Claim 20 (depends on 18)
