Figure 9 is a back view of a sixth embodiment of a circular lighting fixture 10 of the present invention having lights 30 comprising an LED tube.
The base 20 of a lighting fixture 10 of the present invention is an optically transparent sheet or at least non-opaque to some degree and is durable and resistant to impact and damage, within which sheet grooves can be either formed when the sheet is formed or carved out afterwards. For example, the base may be an optically transparent plastic and in a preferred embodiment the base is a polycarbonate, such as LEXAN or MAKROLONS. The base could also be optically transparent sheets made of HDPE (high density polyethylene), acrylic, LDPE
(low density polyethylene) etc. While a preferred embodiment is a base of a clear plastic sheet, the base can be coloured provided that at least some light can penetrate the base.
The lighting fixture of the present invention may be installed on a ceiling or wall, including a concrete surface with or without a lead shield covering. After installation with an appropriate number of attachment means, such as four to twelve concrete fasteners, the lighting fixture of the present invention can additionally be caulked around the edges. The lighting fixture 10 may be
4 waterproofed, for example, with silicon sealant rather than caulking around the edge of the base 20.
The lighting fixture may be manufactured as a grooved plastic sheet through a mold or dye, or a plastic sheet may be rotored or otherwise gouged into channels which fit the desired lights.
In a preferred embodiment of the lighting fixture of the present invention there are no air pockets in order to prevent flex of the base 20 so that the lighting fixture is resistant to impact and tampering. The lighting fixture can resist vandalism in jails and unsupervised areas, can resist damage from impacts in gyms and playrooms, and can avoid impact in parking garages by being of low profile. The low profile and durability of the lighting fixture of the present invention assists in making the lighting fixture impact resistant, for example in any application in which accidental impacts may occur including in any type of vehicle such as drivable machinery, personal and cargo transport automobiles, aircraft, boats and marine applications.
It will be understood that while the invention is preferably comprised of a plastic base and covering of polycarbonate such as LEXAN or MAKROLONCR) that other non-opaque and non-breakable materials now or in future developed which provide similar characteristics of strength and adequate optical transparency may also be used. The covering can be a different material from the material of the base. The shape and size of the lighting fixture may vary from small (for example 2 inches by 3 inches), to large (for example 20 feet by 20 feet) to covering an entire ceiling, and of any shape given the nature of plastics materials. These possible sizes are examples only and the scope of the invention is not limited to these sizes snice the lighting fixture may be smaller than two inches and greater than 20 feet, and the width and length may be different from one another. The figures also only provide some examples of the possible shapes.
In addition to the variability in the shape and size of the plastic base, the thickness of the plastic sheet comprising the base can vary and the edges may be straight, rounded or slanted. The base 20 may be covered with a covering 35 but a covering is not required.
The lighting fixture 10 may be comprised of the base, lights and optionally the covering to be installed by attachment to a floor or wall. In such a lighting fixture the base 20 and covering 35 could sandwich the lights 30 and other components and be held together by gluing or otherwise

The lighting fixture 10 may be comprised of the base, lights and optionally the covering to be installed by attachment to a floor or wall. In such a lighting fixture the base 20 and covering 35 could sandwich the lights 30 and other components and be held together by gluing or otherwise
5 fastening the base to the covering 35 such as by nuts and bolts. Alternatively the components may be fitted together during the installation and the act of installing to a wall or ceiling could fasten the base with lights to the ceiling or wall, or could fasten the base with lights to the covering and to the ceiling or wall.
The lights may be LED lights in strips or tubes or other variety of light that may presently be available or developed in the future which can fit into the grooves carved into a base and not create excessive heat. The grooves and likewise the lights in the grooves may be of any design configurations and the figures provided show just a few embodiments. The lights may be powered with an electrical power source, either directly or through a driver, or by battery, or if for outside use, by solar power.
When the lights are expired, they may be replaced, or the entire lighting fixture may be replaced.
It will be understood that while the lighting fixture of the present invention may be installed flush with a ceiling or wall and directly into an electrical outlet, the lighting fixture of the present invention may also be installed on an existing outlet or mount; however, this may compromise the impact and tamper resistant quality of the lighting fixture of the present invention. The lighting fixture 10 may be installed on ceilings and walls that are not concrete, but the concrete examples illustrate a highly tamper and impact resistant embodiment. A tamper resistant quality is the use of a concrete fastener that is very difficult to remove, because of the shape of the base holes 55 allowing the fastener to be recessed and/or the difficulty in removing the concrete fastener from the concrete, such as due to an anchor of the concrete fastener.
Other than the lighting fixture which is a standalone unit that is not attached to a surface, the appropriate attachment means of the lighting fixture 10 depends on the surface on which it will be attached, for example concrete fasteners for concrete surface, wood screws for wood surface, sheet metal screws for vehicles etc.
The lighting fixture 10 of the present invention, when it is a standalone unit of a base 20 with lights 30 attached to a covering 35, may be placed on a table to function as a drafting table.
