Embodiment Construction

[0027] The present invention allows a durable LED light engine 10 that can be used to illuminate signs. Such as figure 1 As shown, the top of the LED light engine 10 of the present invention is a generally U-shaped top package 20. The generally U-shaped top package 20 includes a plurality of lenses 29. These lenses 29 are located above the LEDs included in the LED light engine 10. The insulated wires 12 and 14 extend from the end of the LED light engine 10. These insulated wires 12 and 14 both provide power to the LEDs and allow the LED light engine 10 to be connected to another LED light engine. The protrusion 50 including the hole 52 formed therein also extends from one end of the LED light engine 10. Fasteners may be located through the holes 52 in the protrusion 50 to attach the LED light engine 10 to the surface. A sealant material 70 that holds the insulated wires 12, 14 in place and acts as a strain relief 71, 72 surrounds the insulated wires 12, 14. The encapsulant...
