Definitions
- the present invention relates to an adapter for a light fitting. It is particularly applicable to an adapter for a downlighter, more particularly to a fire rated downlighter.
- Downlighters that are adapted to be installed into ceiling and/or roof spaces are inherently at risk of compromising the integrity of the ceiling and/or roof space. They are generally installed into an aperture in the ceiling that has to be relatively wide to accommodate the downlighter assembly and thereby compromises the ability of the ceiling to contain a fire in a room or even a fire caused by the light fitting itself failing. In order to compensate against these increased risks, it is generally required that downlighters incorporate adaptations to improve their fire barrier capabilities and which generally include the provision of intumescent materials associated with the downlighter assembly and which expand in the heat of fire to occlude the openings defined by the downlighter.
- Normal measures to fire rate downlighters include, for example, provision of hoods or tents that seat over the downlighter assembly in the manner of a shroud and which effectively entomb the downlighter in event of a fire. See, for example, GB- 2,270,936.
- More recently downlighter assemblies have been adapted to incorporate intumescent material more intimately associated with the downlighter itself and commonly mounted in immediate proximity to the casing of the downlighter at the rear end of the casing in order specifically to occlude ventilation apertures in the rear end of the casing.
- the intumescent material is applied as a sheet/layer that is laminated or sandwiched to the end wall of the lamp casing either internally or externally.
- the positioning of a layer of intumescent material at the end of a downlighter assembly may compromise the flow of air through the downlighter. This can cause excessive heat to build up during operation.
- This has at least two disadvantages. Firstly, bulb life may be significantly reduced and secondly, the intumescent material may be triggered to expand because of the excessive heat resulting from continuous running of the bulb. In order to avoid this, intumescent material which starts to expand at a higher temperature tends to be used. This makes the whole assembly less sensitive and slower to close up in the event of a fire.
- hood or tent Another recent alternative to the hood or tent is the fitting of a raised plate to the top of the outer casing of the downlighter.
- the plate is screwed, bolted or welded into position prior to the downlighter being installed in location.
- the problem is that the plate is not readily retro-fittable to existing downlighter casings and there is still the possibility for material, such as insulation, in the loft or attic space to get between the plate and the top of the outer casing of the downlighter.
- an adapter for a light fitting said adapter including; a first end having a contact portion, said contact portion being adapted to contact the light fitting in use; a second end having a plate portion; a wall portion extending from the first end to the second end; an attachment means adapted to attach to the light fitting in use; and a venting means adapted to allow air to flow through the adapter in use.
- an adapter is advantageous as not only is the adapter retro-fittable to any existing light fitting, in particular to the outer casing of a downlighter, but also allows for the retro-fitting by simply removing the downlighter from the ceiling in the room that it is located in without the need to access the attic or loft space or pull up the floorboards of the room above.
- the adapter is retro-fittable due to the fact that it can simply click into place with existing ventilation apertures in the downlighter casing.
- Suitable attachment means include spring loaded clips which may be formed of metal or plastics material which may in addition include barbs which stop the adapter from becoming dislodged from the light fitting.
- the adapter can be fitted without needing to access the attic or loft space because the adapter is the same size or smaller than the light fitting.
- the existing fitted downlighter can simply be removed from the ceiling, the adapter snap fitted into place on the top of the outer casing of the downlighter and then the downlighter can be put back through the same hole in the ceiling and fitted into place.
- the adapter acts to maintain an air gap and ventilation pathway to the ventilation holes located in the top of the casing of the downlighter. This stops the downlighter from overheating and becoming a fire risk.
- the fitting of the adapter results in a standard downlighter being transformed into a fire rated downlighter at minimal cost and expense, without the need for purchasing a new downlighter or access to the attic or loft space to install a hood or tent over the light fitting.
- the adapter stops the insulation located in most attic or loft spaces (or other ceiling spaces) from coming into contact with the top of the casing of the downlighter which would otherwise risk blocking the ventilation holes, become hot, and risk fire.
- the contact portion is a substantially annular ring, this is to match the annular nature of the casing of the downlighter to which the adapter is to be fitted.
- the plate portion is also substantially annular to match, and the wall portion is also preferably a substantially annular ring substantially perpendicular to the contact portion and/or plate portion. This essentially forms an upside down small bowl or dish shape.
- the contact portion may have substantially the same diameter as the plate portion.
- the wall portion will be parallel and straight sided directly connecting the two elements together.
- the contact portion may have a larger diameter than the plate portion.
- the wall portion includes either a substantially frustoconical portion only or a substantially parallel portion and a substantially frustoconical portion. It is preferable in certain cases for the plate portion and the wall portion to include a cut out portion which corresponds to the location of a transformer fitting on the light fitting which the adapter is to be fitted to in use. If no transformer fitting is present on the light fitting then such a cut out portion will not be required.
- the adapter is either the same diameter or has a smaller diameter than the light fitting which the adapter will be fitted to in use. This enables the adapter either to be retro-fitted or simply fitted to a light fitting which can then be installed through the same size hole in the ceiling as would normally be employed without the need to access the attic or loft space.
- the venting means includes an aperture or a plurality of apertures in the plate portion.
- the venting means includes an aperture or plurality of apertures in the wall portion.
- the apertures may be circular, oval, square or oblong for example.
- the attachment means may include an attachment portion which is adapted to move from a first expanded position to a second contracted position.
- the attachment means is also preferably adapted to attach to the casing of a downlighter utilising a pre-existing hole located in the light fitting which the adapter is to be fitted to in use.
- the attachment portion is adapted to move from the first expanded position to the second contracted position whilst the attachment portion passes through the pre-existing hole during fitting of the adapter in use, and is adapted to move from the second contracted position back to the first expanded position after the attachment portion has passed through the pre-existing hole after fitting of the adapter in use.
- the attachment portion may include a spring-loaded clip or a spring-loaded barb.
- the attachment means may attach to any suitable portion of the adapter; this may be the plate portion or the wall portion or even be located directly on the contact portion.
- the adapter may be formed from a metal or metal alloy or a plastics material.
- the adapter is suitable for any light fittings, but particularly so for a surface mounted light fitting such as one mounted in a wall or ceiling i.e. a downlighter.
- a downlighter i.e. a surface mounted light fitting
- the adapter when fitted will fire rate a standard downlighter, it can also be fitted to already fire rated downlighters to give even greater levels of security and reduce fire risk even further.
- a light fitting including an adapter as described above and in the claims.
- a light fitting including an adapter, said adapter including; a first end having a contact portion which contacts the outer casing of the light fitting; a second end having a plate portion; a wall portion extending from the first end to the second end; an attachment means adapted to attach to the light fitting; and a venting means adapted to allow air to flow through the adapter in use.
