First Claim
Patent Images
1. A lighting device for illuminating indicia of an exit sign having an enclosure with an electrical socket mounted therein, comprising:
- (a) a housing having a plurality of light directing apertures in one side thereof;
(b) illumination means in said housing, said illumination means including a plurality of light emitting diodes mounted On circuit mounting means, at least one of said diodes recessed in each of said plurality of light directing apertures, whereby light from said light emitting diodes is directed by said light directing apertures into the enclosure to illuminate the indicia of the exit sign; and
(c) a mounting base assembly on said housing for electrically connecting said illumination means to the exit sign, said mounting base assembly matingly received in the electrical socket of the exit sign through relative rotational and axial movement therebetween.

11. An exit sign, comprising:
-
(a) a sign housing defining an enclosure therein and having indicia to be illuminated; (b) an electrical socket in said sign housing; and (i) a lighting device housing having a plurality of light directing apertures in one side thereof; (ii) illumination means in said lighting device housing, said illumination means including a plurality of light emitting diodes mounted on a printed circuit board, said lighting device housing having a slot therein in which said printed circuit board is positioned, at least one of said diodes recessed in each of said plurality of light directing apertures, whereby light from said light emitting diodes is directed by said light directing apertures into said enclosure of said sign housing to illuminate said indicia; and (iii) a mounting base assembly on said lighting device housing for electrically connecting said illumination means to said electrical socket, said mounting base assembly matingly received in said electrical socket through relative rotational and axial movement therebetween. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. An exit sign, comprising:
-
(a) a sign housing defining an enclosure with at least one electrical socket therein and having indicia to be illuminated; and (b) at least one lighting device within said enclosure for illuminating said indicia, each lighting device comprising; (i) a lighting device housing having a plurality of light directing apertures in one side thereof; (ii) illumination means in said lighting device housing, said illumination means including a plurality of light emitting diodes mounted on circuit mounting means, at least one of said diodes recessed in each of said plurality of light directing apertures, whereby light from said light emitting diodes is directed by said light directing apertures into said enclosure of said sign housing to illuminate said indicia; and
.(iii) mounting base means on said lighting device housing for electrically connecting said illumination means to said at least one electrical socket, said mounting base means permitting relative movement between said lighting device housing and said at least one electrical socket. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
