The purpose of the protective exterior shade/luminaire provided with a thread base cover and a protective canister with light-distributing thread to protect light bulbs of CLF savings (compact fluorescent lamp) or LED bulb type light bulbs installed in ceramic bases/sockets of the present invention is to protect the light bulbs against weather, dust, water, shock and to provide longer life and better appearance of the light bulbs, furthermore, without the need to remove the ceramic bases/sockets, because the protective exterior shade/luminaire is placed between the light bulb and the ceramic bases/sockets, which results in protective exterior shade/luminaires that are very practical, economical and easy to install, furthermore, the thread of the base cover and of the protective canister ensure a firm assembly and prevent the theft of the light bulb and its parts.
At the present time there are known various exterior shields which protect light bulbs or lamps. Most of these exterior shields have to be fixed on surfaces such as the ceiling and walls by means of screws or some other attachment. In some cases the exterior shield may be fixed on ceramic and/or plastic sockets, and once they have been fixed on such surfaces or on the ceramic and/or plastic sockets, they have to be fixed on the ceiling and walls by means of screws or some other attachment. Once fixed on such surfaces or on the ceramic and/or plastic sockets, it is very difficult to exchange them due to the complicated and permanent or semi-permanent installation. It is also difficult to change the light bulbs or lamps when they have burn out and need replacement or maintenance. Accordingly, there is a need for an exterior lamp or light fixture shade to protect light bulbs, particularly in low-income housing, that is easily attached and removed or otherwise addressed.
In some cases, one purpose of the various external shades is to protect light bulbs or lamps, to provide a sufficiently firm and secure grip by adhering to the surfaces to which they are to be fixed, to allow them to be easily interchanged, and to allow light bulbs or lamps to be changed when they have burn out quickly and safely. However, such external shades present a serious problem due to difficulty in exchanging them due to their complicated (and permanent or semi-permanent) installation, as well as to change the bulbs when they have burn out. Further, in some cases, such shades do not distribute the light efficiently, resulting in external shades that provide poor or diminished light from the light bulb, are uncomfortable and time-consuming to install and to exchange bulbs when they have burn out, that are expensive, and that are overall inconvenient to use and maintain.
Some shades are affixed to a lighting fixture using a flange. Such base cover shades provided with flange can present problems because they do not ensure a sufficiently secure assembly in a firm manner. This allows the theft of the light bulb and its parts by easy detachment by vandals when pulling and extracting it. Accordingly, lighting fixtures/shades for lighting fixtures according to the present invention solves all these problems and inconveniences in an easy and secure manner.
A large number of lighting fixtures and devices are known for both indoor and outdoor uses, many of which utilize and exterior shade or protective cover. However, generally speaking such devices are different from the protective exterior shade/luminaire provided with a thread base cover and a protective canister with light-distributing thread to protect light bulbs of the present invention, because its parts are different as well as its functionality, where the thread of the base cover and the protective canister when assembled by turning and coupling their threads ensure a sufficiently more secure assembly in a firm manner and prevent the theft of the light bulb and its parts by vandals, which results in an advantage for the users.
Furthermore, devices according to the present invention that include a protective exterior shade/luminaire provided with a thread base cover and a protective canister with light-distributing thread to protect light bulbs of CLF savings (compact fluorescent lamp) or LED bulb type light bulbs installed in ceramic bases/sockets against weather, dust, water, shock and to provide longer life and better appearance of the light bulbs, where the thread of the base cover and the protective canister ensure a secure assembly in a firm manner and prevent the theft of the light bulb and its parts as compared to prior art devices.
Document U.S. Pat. No. 4,528,764 provides a suspended ceiling sign is provided for suspension within a vacant panel area, under a light fixture, in a suspended ceiling of a regular array of ceiling panels with each panel being peripherally supported within a suspended grid structure. The ceiling sign includes a hollow enclosure having an open top with a peripheral flange configured to engage the supporting grid structure around the vacant panel area. The enclosure has in one of its sidewalls a cutout portion with a translucent sign mounted therein. The bottom of the enclosure has a directed lighting aperture. Inside the enclosure, there is a truncated pyramidal baffle which is both light reflective and translucent. The pyramidal baffle is seated over the aperture in the enclosure bottom. The truncated top of the baffle may be either open or closed with a translucent material. Thus, light emanating from the lighting fixture above the suspended ceiling is partly reflected from the baffle face through the translucent sign, and partly diffused through the translucent baffle to light the aperture in the bottom of the enclosure. However, this suspended ceiling sign is different from the protective exterior shade/luminaire provided with a thread base cover and a protective canister with light-distributing thread to protect light bulbs of CLF savings (compact fluorescent lamp) or LED bulb type light bulbs installed in ceramic bases/sockets against weather, dust, water, shock and to provide longer life and better appearance of the light bulbs, where the thread of the base cover and the protective canister ensure a secure assembly in a firm manner and prevent the theft of the light bulb and its parts of the present invention, because its parts are different as well as its functionality.
