  • insulated wires 12, 14 both provide electrical energy to the LEDs and enable the connection of one LED light engine 10 to another. Also extending from one end of the LED light engine 10 is a projection 50 including a hole 52 formed therein. A fastener may be placed through the hole 52 in the projection 50 to affix the LED light engine 10 to a surface.
  • a sealant material 70 Surrounding the insulated wires 12, 14 is a sealant material 70 which holds the insulated wires 12, 14 in place and acts as a strain relief 71 , 72. The sealant material 70 provides durability, protects the LED light engine 10 from moisture and holds the components of the LED light engine 10 together.
  • the bottom of the LED light engine 10 is shown in Figure 2. Therein the flat bottom surface 33 of the bottom enclosure 30 is shown.
  • two- sided tape 39 ( Figure 3) may be placed on the bottom surface 33 of the bottom enclosure 30. Use of the two-sided tape 39 provides another way of attaching the LED light engine 10 to a surface.
  • Also shown on the bottom surface 33 of the bottom enclosure 36 are channels 73 filled with solidified sealant material 70. This plastic sealant material 70 is contiguous with the strain relief 71 , 72 formed around the insulated wires 12, 14 at both ends of the LED light engine 10.
  • the molten plastic sealant material 70 then flows into the openings between the substantially U-shaped top enclosure 20, the printed circuit board 40 and the bottom enclosure 30.
  • the solidified plastic sealant 70 seals the LEDs 60 and electrical componentry 62 from damage by moisture, provides strain relief around the insulated wires 12, 14, holds the wires in place within the LED light engine 10 and affixes the substantially U-shaped top enclosure 20, the printed circuit board 40 and the bottom enclosure 30 one to another.
  • FIG. 4A Shown in Figure 4A is a top view of the printed circuit board 40. Note that three LEDs 60 are located on the top surface 42. While three LEDs 60 are shown in the preferred embodiment, the number of LEDs 60 located on the top surface 42 of the printed circuit board 40 is dependent on the application of the LED light engine 10 and the amount of light required. In the middle of the printed circuit board 40 is an alignment hole 48 and an alignment slot 46. While an alignment hole 48 and an alignment slot 46 are shown, those of ordinary skill in the art will understand that one or more holes or one or more slots may be used for alignment. Formed around the side of the printed circuit board is an edge 49.
  • FIG. 4B Shown in Figure 4B is a bottom view of the printed circuit board 40.
  • various pieces of electronic componentry 62 to include resistors, diodes and integrated circuit chips, are located on the bottom 43 of the printed circuit board 40. If needed, some or all of the wires and electronic componentry may be placed on top of the printed circuit board 40.
  • pads 45 are located on the bottom 43 of the printed circuit board 40.

  • lenses 29 are formed in the top surface 24 of the substantially U-shaped top enclosure 20.
  • Each one of these lenses 29 is constructed, positioned and arranged to manage the light rays emitted by the LEDs 60. While three lenses 29 are shown in Figure 5A, the number of lenses depends on the number of LEDs positioned on the top surface 42 of the printed circuit board 40.

  • the downwardly depending ends 22 include arcuate openings 13, 15 which assist in the placement of the insulated wires 12, 14 when the substantially U-shaped top enclosure 20, the printed circuit board 40 and the bottom enclosure 30 are assembled together.
  • FIG. 5B Shown in Figure 5B is a bottom view 23 of the substantially U-shaped top enclosure 20. Also visible are the lens openings 27.

The rightmost well 31 in Figure 6A is large enough to accommodate the electronic componentry 62 which may be positioned on the bottom 43 of the printed circuit board 40 ( Figure 4B). The wells 31 in Figure 6A contain at least one alignment receptacle 32 into which the alignment projections 26, 28 formed in the bottom of the substantially U-shaped top enclosure 20 pass into after having passed through the alignment hole 48 and an alignment slot 46 formed in the printed circuit board 40. On one end of the bottom enclosure 30 is the projection 50 shown in Figure 1. As described below, a portion 18 of top surface 34 will eventually come into physical contact with the bottom surface 43 of the printed circuit board 40.
  • the flat bottom surface 33 of the bottom enclosure 30 As noted above with respect to Figure 3, the flat bottom surface 33 of the bottom enclosure 30 includes the channels 73 formed therein which will provide paths for the molten plastic sealant material 70 as shown in Figure 2. It is anticipated that the bottom support enclosure 30 will be manufactured from PMMA, a polycarbonate, an ABS plastic, nylon or PVC.

Portion 18 of the top surface 34 of the bottom enclosure 30 is placed against the bottom 43 of the printed circuit board 40. The edge 49 of the printed circuit board 40 is positioned within the insides of the downwardly dependent sides 21 of the substantially U-shaped top enclosure 20. The flat portion 19 of the bottom 23 of the substantially U-shaped top enclosure 20 is placed against the top surface 42 of the printed circuit board 40.
  • the combination shown in Figure 7 illustrates the openings available for the flow of molten sealant material 70 after the combination of the substantially U-shaped top enclosure 20, the printed circuit board 40 and the bottom enclosure 30 have been placed together.
  • the openings 91 formed in the bottom 92 of the plastic mold 90 are sized to engage the lenses 29.

  • the molten plastic sealant material 70 also bonds with the edges 49 of the printed circuit board 40.
  • the molten plastic sealant material 70 also chemically bonds with the bottom enclosure 36 thereby affixing the substantially U-shaped top enclosure 20, the printed circuit board 40 and the bottom enclosure 30 one to another.
  • the sealant material 70 does not flow over the top surface 42 of the printed circuit board 40.

Such flow of the sealant material 170 is also illustrated in Figure 11 and in Figure 11 A. While no portion of the sealant material 170 comes into contact with the printed circuit board 140, the sealant material 170 holds the components of the first alternate embodiment of the LED light engine 110 together and seals the electric componentry contained therein from the corrosive effects of moisture.
