Abstract

Lighting system mountable on a surface and including one or more miniature light sources and a multi-part housing including recesses for accepting the light sources and an electrical supply line. The light sources can include light emitting diodes. Separate parts of the housing are mated in a manner to fix the position of the electrical supply line between them, and may be formed with a recess that receives an asymmetrically shaped electrical supply line in only one possible orientation. Similarly, the recesses receiving the light sources may be shaped such that electrical connections with proper polarity are assured. Either or both parts of the housing may be fastened to the surface with adhesives and/or optional holes for receiving pins, nails, screws, bolts or the like. The lighting system is particularly suitable for emergency, railing, landscape and vehicle illumination applications, and may be powered by batteries and renewable energy sources.

Claims

19-1. The lighting system of claim 1, wherein the housing further includes a plurality of through holes through the width of the housing through which the housing is fastenable to a surface.

21. A miniature light, comprising:

an opaque housing having a top portion and a bottom portion, the top portion including an opening and an inside surface;

at least one light source located in the opening of the top portion of the housing for providing illumination to a region external to the housing through the opening;

an electrical component assembly comprising a first insulated conductor having a negative lead connected to the at least one light source, a resistor connected to the at least one light source, and a second insulated conductor having a positive lead connected to the resistor, the electrical component assembly located within the housing;

wherein the first insulated conductor and second insulated conductor each have an end extending out of the housing having sufficient strength and rigidity to puncture an insulating coating of an electric supply line.

22. The miniature light of claim 21, wherein the insulated conductor ends each exhibit one or more sharp features to facilitate puncture of the insulating coating of the electric supply line.

23. The miniature light of claim 21, further comprising:

a sealant surrounding the electrical component assembly within the housing, the sealant affixing the electrical component assembly within the housing; and

a means for preventing the sealant from exiting the opening.

24. The miniature light of claim 21, wherein the at least one light source is a light emitting diode.
