Abstract

A tread area and step edge illumination system is disclosed which comprises a base member configured for attachment to an exposed edge or surface of a step or stair. The base member has a downwardly projecting rearward wall and a forwardly and downwardly extending forward wall portion, a downwardly facing opening being defined between the rearward and forward walls. A light strip assembly having an elongate light strip with a number of longitudinally spaced-apart miniature lights, for example pre-focused LED'"'"'s, mounted to the strip. The light strip assembly is detachably mounted to the base member so that light from the miniature lights on the light strip is directed downwardly through the downwardly facing opening when the lights are lit, the light strip assembly being mounted to the base member so that the light strip assembly can be selectively adjusted through an angle of about 60° to enable selective adjustment of the direction of light from the light strip assembly. A diffuser lens may be detachably mounted to the base member so that the lens is in the path of light from the light strip assembly when the lights are lit.

Claims

1. A tread area and step edge illumination system which comprises:

(b) a light strip assembly having an elongate light strip with a number of longitudinally spaced-apart miniature lights mounted to the strip; and

(c) means for detachably mounting said light strip assembly to said base member so that light from the miniature lights on the light strip is directed downwardly through said downwardly facing opening when said lights are lit, said means for detachably mounting the light strip enabling angular adjustment of said light strip assembly through a given pivotal angle so as to enable the selective direction of light from the light strip assembly through said given pivotal angle.

2. The tread area and step edge illuminating system as claimed in claim 1, wherein said given pivotal angle is between 0°

and about 60°

.

3. A tread area and step edge illumination system which comprises:

(a) a base member configured for attachment to an exposed edge or surface of a step or stair, said base member having a downwardly projecting rearward wall and a forwardly and downwardly extending forward wall portion, a downwardly facing opening being defined between said rearward and forward walls, at least a forwardly extending, upper region of said forwardly and downwardly extending forward wall portion being constructed to form part of a step tread surface when said system is installed on a step edge;

(b) a light strip assembly having an elongate light strip with a number of longitudinally spaced-apart miniature lights mounted to the strip; and

(c) means for detachably mounting said light strip assembly to said base member so that light from the miniature lights on the light strip is directed downwardly through said downward facing opening when said lights are lit, said means enabling angular adjustment of the light strip assembly through a given pivotal angle so as to enable the selective direction of light from the light strip assembly through said given pivotal angle.

4. The tread area and step edge illuminating system as claimed in claim 3, wherein said given pivotal angle is about 60°

.

5. The tread area and step edge illuminating system as claimed in claim 3, including a lens and means for detachably mounting said lens to said base member so that the lens is in the path of light from said light strip assembly when said lights are lit, said lens being configured for diffusing light passing through the lens.

6. The tread area and step edge illuminating system as claimed in claim 3, wherein said lights comprise pre-focused light emitting diodes.

7. A tread area and step edge illumination system which comprises:

(a) a base member configured for attachment to an exposed edge or surface of a step or stair, said base member having a downwardly projecting rearward wall and a forwardly and downwardly extending forward wall portion, a downwardly facing opening being defined between said rearward and forward walls, at least a forwardly extending, upper region of said forwardly and downwardly extending forward wall portion being constructed to form part of a step tread surface when said system is installed on a step edge;

(b) a light strip assembly having an elongate light strip with a number of longitudinally spaced-apart miniature lights mounted to the strip, said lights comprising of pre-focused light emitting diodes; and

(c) means for detachably mounting said light strip assembly to said base member so that light from the miniature lights on the light strip is directed downwardly through said downward facing opening when said lights are lit, said means enabling angular adjustment of the light strip assembly through a given pivotal angle so as to enable the selective direction of light from the light strip assembly through said given pivotal angle.

8. The tread area and step edge illuminating system as claimed in claim 7, wherein said given pivotal angle is about 60°

.

9. The tread area and step edge illuminating system as claimed in claim 7, including a lens and means for detachably mounting said lens to said base member so that the lens is in the path of light from said light strip assembly when said lights are lit, said lens being configured for diffusing light passing through the lens.
