Problems solved by technology

[0006] Attempts have been made to place a normal screen in front of the light bulb to limit such disturbances or effects which often also result in limiting all the light emitted by the lighting fixture
[0007] Therefore, although such known lighting devices fulfill their lighting function satisfactorily, they do not fully improve their quality of use and the lighting place in which they are installed.

Embodiment Construction

[0017] Referring to the accompanying drawings, there is shown a semi-recessed lighting device with a concentrated light beam according to the present invention, which is generally indicated by reference numeral 10 in both embodiments.

[0018] The lighting device 10 is connected, for example, to a plasterboard ceiling 11 in which an opening 12 is made. Lighting device 10 includes an outer housing or housing 13 received within aperture 12 , a bulb socket unit 14 including corresponding bulb sockets 15 , and a filler ring 16 projecting from suspended ceiling 11 .

[0019] More particularly, thanks to the provision of a telescoping frame 17 for fastening to the suspended ceiling 11, the outer casing or shell 13 is accommodated in the opening 12, for example circular. Furthermore, the outer shell or housing 13 has, on the outside of its end face, a peripheral portion 18 , for example raised in the circumferential direction, which ensures a tight fit with the plasterboard suspended...

Abstract

A semi-built-in lighting apparatus with concentrated beam (10) comprising a containment body or outer casing (13), which is housed in an opening (12) of a false ceiling (11), a bulb socket unit (14), with respective reflector (27), and an outer filling ring (16), in which apparatus the outer filling ring (16) foresees an inner seat (31) for housing at least one glass insert (32) and freely removable fastening means (19, 20) to the containment body or outer casing (13), a central cylindrical element (28, 29) with a limited diameter carrying at least one transparent piece of glass (36, 37) and being fixed in a central hole (33) of said at least one glass insert (32).

Description

technical field [0001] The invention relates to a semi-recessed lighting device with a concentrated light beam. Background technique [0002] The types of recessed and semi-recessed lighting fixtures that currently exist are very different and vary in application form and usage. This type relates in particular to the surface on which the device is applied and the light it wants to emit. [0003] Also, in semi-recessed lighting installations, the simplicity of installation and adjustment in the installation must be taken into account, avoiding any possible elements that could create difficulties for the operator. [0004] In particular, in semi-recessed lighting installations, when a large amount of light has to be emitted in a concentrated beam, various solutions can be derived from the specific operation required. [0005] Furthermore, in known devices of the kind cited above, undesired effects such as "dark spots" occur in different areas thereof, and the asymmetrical or...
