The ceiling is characterized in that a plurality of LED lamps are fixedly embedded in a light bar (2); the bar (2) is mounted on the side edges of two adjoining ceiling boards (1) fitted and held firmly by the standard ceiling grids.

Description

DESCRIPTION
TITLE OF INVENTION: LIGHTING ASSEMBLY FOR CEILING BOARD
TECHNICAL FIELD
The invention relates to light fittings on ceiling boards, and is particularly applicable to light fittings such as modularized composite LED lamps arranged in a metal bar. The assembly illustrated in the present invention has the advantages of simple structure.
BACKGROUND
Conventionally, ceiling boards comprise a grid of intersecting members in the form of metal tracks suspended below a ceiling. The metal tracks have horizontal flanges at their lower ends which are used to support ceiling panels. The cavity formed above the ceiling panel is used to pass electrical service wires to which light fittings of various sorts may be connected. Fluorescent light tubes may typically be attached to fittings placed on the grid tracks, which are approximately the size of the spacing and thus will replace a panel in that spacing. However, when bulb lights such as halogen lights are used the fittings are smaller and thus entire panels are not removed. Instead modified panels are used and the lamp fitting is either mounted directly on the panel, or else a subsidiary track is fastened to the ceiling underneath the panel, the panel having a hole for the wires to connect to the lights. Some expense is therefore involved when mounting lamps on existing ceilings because ceiling panels have to be replaced with modified panels. Even when the fittings are placed below the ceiling panels the panels still have to be modified to pass the electrical cables from the ceiling cavity. Halogen lamps have relatively high power requirements and consequently require relatively large wires whose appearance below the ceiling panels would generally be considered unsightly.
The present invention in some embodiments therefore aims to provide electrical fittings such as modularized composite LED lamps that can be attached to a ceiling board arrangement of which said LED lamps are fixedly embedded onto a light bar. The present method of ceiling lighting assembly described does not require modification or replacement of existing ceiling panels or like components as the LED light bar is designed to be firmly fitted and held by the standard ceiling grids.
SUMMARY
In accordance with a first aspect of the invention there is provided an electrical appliance comprising of a metal bar with a plurality of LED lamps embedded within the said bar.
The LED light bar is to be mounted within a ceiling board. The LED bar is specifically adapted for mounting on a member of the ceiling board which is firmly fitted and held by ceiling grid at the two adjoining ends. The LED light bar is manually releasable fixing to the board of which a configuration such that they can be engaged to ceiling board. The engaging means, and indeed the entire bar, could be made of aluminum material, of a thickness sufficiently small so as not to disturb the positioning of a ceiling boards. The electrical apparatus, which is LED lamp in this case, will further include an electrical appliance having wiring emerging from the LED bar connected to electrical supply which is to be hidden above the ceiling;
According to a second aspect of the invention there is provided a suspended ceiling grid with a single metal bar comprising a plurality of LED lamps arranged to form part of the grid on the ceiling board. The fitting can be placed at an arbitrary location on the ceiling board and subsequently moved if desired without any residual damage to the ceiling board.
According to a third aspect of the invention there is provided a method of mounting a lamp fitting on a suspended ceiling of the kind having ceiling panels fitted in the spaces defined by the ceiling board, comprising the steps of: attaching the . lamp fitting in between two pieces of ceiling board, and running a wire from the fitting towards a power supply above the ceiling through a gap between the track and the ceiling board resting on the track in such a way that the ceiling board is not substantially displaced by the wire. Lamp fittings according to embodiments of the invention may be applied to existing ceilings without further modification to any component of the ceiling.
The present invention is particularly conceived for low power consumption in the range of 12.5watt. Another advantage of the present invention is the easy and convenient fitting of celing lights on ceiling boards which requires relatively low power requirements and consequently require relatively small wires whose appearance above the ceiling panels would portray a neat and orderly of wire arrangements.
For a better understanding of the invention and to demonstrate how it may be put into practice embodiments of it will now be described with reference to the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG.. 1 is a view of the ceiling board before the fitting of the lamp fixture
FIG.2 is a view of the placement of lamp fitting in a light bar in accordance with the invention together with an isometric view of the light bar
FIG. 3 shows the light fitting connected to a power supply FIG. 4 is a view of the lamp fitting mounted on a ceiling board DETAILED DESCRIPTION OF THE INVENTION
In FIG. 1 the ceiling board ( 1 ) which is used more commonly in offices is cut into two pieces. A light bar (2) which is readily fixed embedded with a plurality of LED lamps (3) is then mounted to the side edge of the wall of the first ceiling board (l a). The light bar (2) has a generally rectangular shape in plan. It is understood that a fraction of the ceiling board is cut away for the fitting of the LED light bar (2) fixed to the adjoining ceiling board (l a, lb).
The base of the LED lamps (3) fitted inside the light bar (2) has a recess into which the wirings (4) are connected to a power supply (5) shown in FIG. 3. The power supply (5) is to be hidden inside the ceiling.
The second ceiling board (lb) is then mounted to adjoining LED .light bar (2), each of which has a cross-section which the contact surfaces of the LED light bar (2) and the ceiling board is attached together, of which the two ends (6a, 6b) of the LED light bar (2) is adapted to be fitted and held firmly by the standard ceiling grids, which forms the part that is visible to the occupant of the room in which the ceiling is fitted as shown in FIG. 2 and FIG. 4.
The fitting described is very inconspicuous and offers a neat yet inexpensive way of fixing the lamp to the ceiling without any modification of the panels or drilling into the grid. Moreover the panels are not disturbed by the thin wires passing between them and the ceiling.
Because the invention fixes the appliance to the ceiling grid by a non-destructive manner, involving frictional engagement or clamping around the outside of the ceiling grid, in the first place the appliance can be fitted at will anywhere on the grid, and in the second place no drilling or intermediate fittings are needed; this is both convenient and preserving of the fabric of the ceiling.
