Abstract

Cube-shaped, ventilated, individual light modules housing a lamp or bulb having different predetermined characteristics are interchangeably mounted on an expandable clip surrounding an electrical socket, by sliding the module down on the clip and simultaneously establishing electrical contact between the bulb in the module and a power source and switch. The front of the module is faced with safety glass to protect the bulb and subject, and a space is provided between the module and protective safety glass which can be fitted with one or more, swing-away, wide angle adapter, diffuser, or dichroic lenses.

Claims

1. A modular light assembly comprising:

a base member,

at least one electrical socket means pivotably mounted on said base member,

a light module having

a housing adapted to mount a lamp, said housing including a pair of sideplates and a hood pivotably mounted to said sideplates and pivotable from a first position forming an enclosure with said sideplates to a second position permitting access to the interior of said enclosure for removing and replacing a lamp mounted therein,

means for securing said module onto said electrical socket means, and

means between said electrical socket means and module for releasably retaining said module on said electrical socket means, with the lamp in said module in electrical contact with said electrical socket means, and

means on said base member for securing said base member to a support, said means including a pocket on the module slidably received on the electrical socket means.

2. The light assembly of claim 1 wherein said pocket received on said electrical socket means is formed by

a rearplate extending between said sideplates and

a backplate spaced from said rearplate.

3. The modular light assembly construction of claim 2 wherein said rearplate includes an opening therein adapted to receive a portion of a lamp mounted in said module enclosure and extending into said pocket.

4. The light assembly of claim 3 wherein said electrical socket means is substantially upright and includes

a resilient clip construction having a pair of legs connected by a top wall, one of said legs being at an obtuse angle with respect to said top wall, said legs being received in said pocket between said rearplate and backplate on said light module.

5. The light assembly of claim 4 wherein said resilient clip construction includes

a cut-out in one of said legs adjacent the rearplate of said module and the top wall connecting said legs adapted to receive in sliding engagement the electrical contact portion of said lamp mounted within said light module enclosure extending into said pocket.

6. The light assembly of claim 5 wherein said electrical socket means includes

a dielectric block disposed between said legs of said clip which includes a pair of slots adapted to receive the portion of said lamp extending into said cut-out and

means within said slots for forming an electrical connection to said lamp portion extending into said cut-out.

7. The light assembly of claim 6 including electrical switch means on said base member electrically connected to said electrical connections in said dielectric block of said socket means.

8. The light assembly of claim 7 including

a third leg on said clip construction between said first and second legs,

means between said second and third legs for securing said dielectric block therebetween, and

an arcuate portion connecting said second and third parallel legs secured to shoulder washers pivotably mounted on said base member.

9. The light assembly of claim 8 including

an opening in said backplate of said module, and

the means between said second and third legs for securing said dielectric block therebetween having a detent head adapted to be received in said opening in said backplate to lock said electrical socket means to said module backplate.

10. The light assembly of claim 9 including a safety visor permanently mounted on the front of the hood of said module.

11. The light assembly of claim 10 wherein said safety visor is spaced from at least one interior surface of said hood, and

a removable lens is pivotably mounted on said hood in said space in fromt of said safety visor.

12. The light assembly of claim 11 wherein said visor is spaced from the interior surface of said hood by a washer, and

said removable lens includes

a frame, and

a mounting plate pivotably connected to said frame including a slot opening along one edge thereof adapted to be disposed about said washer, the sidewalls defining said slot being frictionally engaged on said washer.

13. The light assembly of claim 1 including a safety visor permanently mounted on the front of the hood of said module.

14. The light assembly of claim 13 wherein said safety visor is spaced from at least one interior surface of said hood, and

a removable lens is pivotably mounted on said hood in said space in front of said safety visor.

15. The light assembly of claim 14 wherein said visor is spaced from the interior surface of said hood by a washer, and

said removable lens includes

a frame, and

a mounting plate pivotably connected to said frame including a slot opening along one edge thereof adapted to be disposed about said washer, the sidewalls defining said slot being frictionally engaged on said washer.
