## Abstract

There is provided a flangeless recessed lighting fixture assembly that includes a pair of adjustable length brackets, a configurable elevating mechanism including operationally connectable to a recessed LED fixture and at least one elevating subassembly; the method of installing in a non-limiting manner includes: adjusting a length of the adjustable length brackets to a customized length, longitudinally translating the configurable elevating mechanism along the adjustable length brackets, adjusting a horizontal position of the static moiety along the adjustable length brackets; adjusting a vertical position of the dynamic moiety relative to the static moiety, by the elevating subassembly and leveling the dynamic moiety relative to the static moiety.

## Claims

### Claim 1

A flangeless recessed lighting fixture assembly comprises:
a. a lighting element;
b. a recessed LED fixture configured for accommodating said lighting element, comprising a bottom opening on a bottom face thereof and a top opening on top face thereof;
c. an encasement configured for covering and enclosing said recessed LED fixture;
d. a pair of adjustable length brackets operationally connectable to said recessed LED fixture;
e. mounting plates at terminal portions of said of adjustable length brackets, configured for mounting onto constructional elements of a building;
f. a configurable elevating mechanism comprising:
i. a static moiety, operationally connectable to said adjustable length brackets, and
ii. a dynamic moiety operationally connectable to said recessed LED fixture and forming a slidable arrangement with said static moiety, and
iii. at least one elevating subassembly, operationally connecting said dynamic moiety to said static moiety;
wherein said adjustable length brackets are configured for adjustably extend between opposing constructional elements of a building, thereby facilitating a first degree of freedom in adjustment of flangeless recessed lighting fixture assembly, by adjusting said adjustable length brackets to a customized length;
wherein said static moiety of said configurable elevating mechanism is longitudinally translatable along said adjustable length brackets, thereby facilitating a second degree of freedom of said flangeless recessed lighting fixture assembly, by adjusting a horizontal position of said static moiety along said adjustable length brackets;
wherein said at least one elevating subassembly is configured for adjusting a position of said dynamic moiety relative to said static moiety, thereby facilitating a third degree of freedom of said flangeless recessed lighting fixture assembly, by vertically leveling said dynamic moiety along a longitudinal axis of said elevating subassembly;
wherein said elevating subassembly of said configurable elevating mechanism comprises a headbolt terminating with a cup, rotatably screw-threaded into an aperture in at least one member, selected from the group consisting of:
said static moiety and said dynamic moiety.

### Claim 2 (depends on 1)

The flangeless recessed lighting fixture assembly as in claim 1, wherein said adjustable length brackets comprise at least one telescopic adjustable shaft.

### Claim 3 (depends on 1)

The flangeless recessed lighting fixture assembly as in claim 1, wherein said encasement is secured to said recessed LED fixture by an interconnecting part.

### Claim 4 (depends on 1)

The flangeless recessed lighting fixture assembly as in claim 1, wherein said static moiety further comprises an orthogonally protruding plate, whereas said dynamic moiety further comprises an orthogonally protruding plate, configured to be operationally connected to said orthogonally protruding plate of said static moiety by said elevating subassembly of said configurable elevating mechanism.

### Claim 5 (depends on 1)

The flangeless recessed lighting fixture assembly as in claim 1, wherein at least one member, selected from the group consisting of: said static moiety and said dynamic moiety, further comprises lateral extensions protruding laterally outwards from side faces thereof.

### Claim 6 (depends on 1)

The flangeless recessed lighting fixture assembly as in claim 1, wherein at least one member, selected from the group consisting of: said static moiety and said dynamic moiety, further comprises lateral grooves, extending along lateral edges thereof.

### Claim 7 (depends on 6)

The flangeless recessed lighting fixture assembly as in claim 6, wherein said grooves are formed by a centrical plate and two right-angled profiles.

### Claim 8 (depends on 1)

The flangeless recessed lighting fixture assembly as in claim 1, wherein said elevating subassembly of said configurable elevating mechanism further comprises a biasing means configured for driving said dynamic moiety away from said static moiety.

### Claim 9 (depends on 1)

The flangeless recessed lighting fixture assembly as in claim 1, wherein said configurable elevating mechanism is configured to prevent rotation of said dynamic moiety relative to said static moiety.

### Claim 10 (depends on 1)

The flangeless recessed lighting fixture assembly as in claim 1, wherein said configurable elevating mechanism is configured to prevent any movement of said dynamic moiety relative to said static moiety other than said adjusting of said position of said dynamic moiety relative to said static moiety along said longitudinal axis of said elevating subassembly.

### Claim 11 (depends on 1)

The flangeless recessed lighting fixture assembly, as in claim 1, further comprises a covering mounting plate, operationally connected to a bottom face of said dynamic moiety.
