Abstract

An integral conduit modular lighting system that has a light board having circuitry that is secured to a heat sink with an adhesive layer. The heat sink has a gasket in order to securely connect the lighting system to a preexisting conduit body such that the lighting system withstand a high pressure wash without leakage to the board. The heat sink also has opening that mate with openings of preexisting electrical conduit bodies to provide installation of the modular lighting system to existing electrical conduit bodies.

First claim

What is claimed is:

1. A device for illumination, comprising:
a conduit body;
a light board including electrical circuitry on a substrate with a first side and a second side defining opposing planar surfaces;
a light engine module comprising an array of light sources arranged on the first side of the substrate with driving circuitry that supplies electrical excitation to the array of light sources;
said second side engaging an adhesive layer to secure the light engine module to a heat sink;
said heat sink mounted on the conduit body;
a lens module having an interior lens surface engaged and secured to the adhesive layer to provide a water tight seal to prevent the entry of water onto the electrical circuitry; and
a gasket secured to the heat sink.

2. The device of claim 1 further comprising at least one mounting hole for securely mounting the light engine module in a fixed position relative to the conduit body.

3. The device of claim 1 , wherein the conduit body comprises an industry standard electrical junction box.

4. The device of claim 1 wherein when the light engine module is securely mounted to the conduit body the gasket engages the conduit body to prevent water from entering the conduit body.

5. The device of claim 1 , wherein the electrical excitation signals comprise an alternating current (AC) signal.

6. The device of claim 1 wherein the array of light sources are light emitting diodes.

7. The device of claim 1 wherein the substrate is a printed circuit board.

8. A method of installing a device for illumination in a chicken coop installation to prevent the flow of water within the device, steps comprising:
providing an electrical conduit connected to corresponding ports of an integral light module having a conduit body;
said integral light engine module further comprising an array of light sources arranged on a substrate having a first side and a second side defining opposing planar surfaces;
adhering the substrate to a heat sink with an adhesive layer;
securing a lens to the heat sink against the adhesive layer to seal the substrate from water; and
mounting the heat sink to the conduit body to prevent water from entering the conduit body; and
securing a gasket to a side of the heat sink opposite the substrate.

9. The method of claim 8 further comprising the step of pressing the gasket against the conduit body to provide a water tight seal.

10. The method of claim 9 wherein the gasket is made of a flexible material that deforms when the gasket is pressed against the conduit body.

11. The method of claim 9 wherein the array of light sources are light emitting diodes.
