Abstract

An illustrative modular light fixture apparatus may comprise a plurality of modules, each having a base component and a cover component. The base component has a split vertical male plug positioned within a cylindrical recess, and a cylindrical female receptacle formed at an opposite end thereof. The cylindrical female receptacle and split male plug are so configured such that the female receptacle of one module will snap fittingly or otherwise interconnect with the split male plug of another module. The cover component has respective pairs of rectangular openings on first and second sides thereof configured to snap fittingly engage respective tabs on the sides of the base component as the cover component is pushed downwardly over the base component to thereby attach the cover component to the base component.

Claims

1. An LED light fixture apparatus comprising:

a first base component having respective pairs of vertically projecting resilient tabs on first and second sides thereof, each resilient tab having a plurality of vertical ridges formed thereon;

the first base component further having a cylindrical recess formed at a first end thereof and a split vertical male plug positioned within the cylindrical recess;

the first base component further having a cylindrical female receptacle formed at a second, opposite end thereof and positioned within first and second outer fingers, the cylindrical female receptacle having a hole therein;

a second base component further having a cylindrical recess formed at a first end thereof and a split vertical male plug positioned within the cylindrical recess;

the second base component further having a cylindrical female receptacle formed at a second, opposite end thereof and positioned within first and second outer fingers, the cylindrical female receptacle having a hole therein;

the cylindrical female receptacle and split male plug of each of the first and second base components being so positioned, shaped, and dimensioned that the female receptacle of the first base component snap fittingly engages or otherwise interconnects with the split male plug of the second base component; and

a cover component having respective pairs of openings on first and second sides thereof and respective depending surfaces located beneath each of the openings, the openings being so positioned, shaped and dimensioned that respective inner surfaces of the depending surfaces initially respectively contact the vertically projecting resilient tabs of the first base component as the cover component is pushed downwardly over the first base component, thereby pressing the pairs of tabs inwardly and thereafter allowing the tabs to snap fit into the respective openings in the respective sides of the cover component to thereby attach the cover component to the first base component.

3. The LED light fixture apparatus of claim 1 further comprising a conduit feed clamp pivotally mounted at an end of said second base component and configured to receive and hold an electrical conduit feed.

4. The LED light fixture apparatus of claim 1 further comprising a pin holder attached to an underside of the cover component and configured to receive a plurality of electrical leads, the pin holder having two power pins positioned to supply power to a plurality of LEDs mounted on a circuit board located on a top side of said cover component.

5. The LED light fixture apparatus of claim 1 wherein said cover member has an interior and wherein a rectangular edge or lip is formed in said interior and, said lip providing a ledge upon which rests a lens, said lip lying adjacent a vertical wall, said vertical wall further serving to position the lens.

6. The LED light fixture apparatus of claim 5 further comprising a circuit board located on a floor portion of the cover member below said lens.

7. The LED light fixture apparatus of claim 3 wherein said conduit feed clamp comprises (a) a circular rear portion with an outer circular vertical wall surrounding a flat floor and (b) a cylindrical vertical boss with a threaded cylindrical interior centrally positioned on said floor.

8. The LED light fixture apparatus of claim 7 wherein said conduit feed clamp further comprises a front entry way of generally rectangular cross-section and a cable-receiving opening.

9. The LED light fixture apparatus of claim 1 further comprising a mounting track, the mounting track including respective side fingers each extending through a respective hole in respective horizontally extending side tab formed on said second base component, each finger being configured to engage a tab located on a respective side of the second base component, the mounting track further comprising respective first and second parallel upright supports, each of which abuts a bottom surface of the second base component.

10. The LED light fixture apparatus of claim 1 further comprising a mounting track containing a flat vertical portion connected to a horizontal base portion, the horizontal base portion including respective lingers extending through respective holes in respective horizontal extending tabs formed on said second base component, said fingers further being configured to grip respective tabs formed on respective side surfaces of the second base component.

2. The LED light fixture apparatus of claim I wherein the engagement or interconnection between the female receptacle of the first base component and the split male plug of the second base components enables the first and second base component to pivot with respect to one another.
