Definitions

  • the present invention relates to the provision of emergency lighting and signage in buildings and in particular the invention provides an improvement to the construction of illuminated emergency signs which incorporate an emergency lighting function.
  • Prior art illuminated emergency signs take a number of forms. These include streamlined designs centering on thin, edge lit, sign carrying blades, incorporating a light transmitting core extending from a lamp housing containing a fluorescent tube adjacent an edge of the blade as well as batteries, inverter and control circuits. At the other end of the scale, less expensive but bulkier rear illuminated signs are commonly found to be in use, in which the sign housing includes space behind a single sign panel or between bi-directional signs in which one or more fluorescent lamps are located. In each of these known sign types only limited illumination if any is available for emergency lighting.
  • the illumination source is located within the same housing as the supply terminations, the inverter electronics and batteries, each of which carry dangerous electrical potentials when in use.
  • Safety regulations dictate that the installation and maintenance of such signs should be carried out by a qualified electrician who will be well aware of the dangers and trained to work on live circuits. This requirement extends to the apparently simple task or changing light globes of tubes, as emergency lighting is by regulation required to be connected to an un-switched and unfused circuit in order that the power to illuminate the sign cannot be accidentally interrupted in normal conditions. Therefore, lamps must be replaced under live conditions.
  • Embodiments of the present invention by comparison provide improved illumination in emergency lighting conditions while providing relatively even illumination (with reference to legal requirements) through sign carrying surfaces. Further, the spaced location of heat generating components can result in a reduction of thermal stress on sensitive electrical and electronic components.
  • references to even distribution of light are intended to be read as meaning sufficiently even distribution to meet the relevant standard applicable to the device or the particular feature of the device (eg, standards relating to even illumination of emergency signs or even distribution of light emitted from an emergency light).
  • the present invention consists in a sign carrying element for an illuminated sign, the sign carrying element arranged to be removably connected to a cooperating base, the sign carrying element having internal light source arranged to project light through a sign carrying surface of the sign carrying element and the internal light source being supplied with electrical power by way of electrical connection means located at one edge of the sign carrying element to engage with a cooperating electrical connection means in the base when the sign carrying element is connected to the base.
  • the electrical components required to condition the electrical power supplied to the internal light source, for starting and maintaining operation of the internal light source are not located within the sign carrying element but are instead located in the base.
  • the sign carrying element includes more than one light source, and at least one of the light sources is located towards an edge of the sign carrying element, distal from said one edge at which the electrical connection means is located.
  • the present invention consists in a sign carrying element having at least one sign carrying surface and illumination means, including a light source located in a cavity in the sign carrying element and two light conducting members having light receiving surfaces positioned to accept light radiated from the light source the light conducting members being adjacent and substantially parallel to one another and respectively having outwardly facing surfaces at least one of which forms the sign carrying surface of the sign carrying element and, inwardly facing surfaces which are stepped or corrugated to cause light in each of the light conducting members to be refracted and/or reflected efficiently through the respective facing surfaces and projected through the light conducting members to thereby evenly back illuminate the outwardly facing surfaces of the light conducting members.
  • the present invention consists in a sign carrying element having at least one sign carrying surface and illumination means, including a light source located in a cavity in the sign carrying element and two light conducting members defining between them a tapered cavity reducing in width away from the light source, the light conducting members being adjacent to one another and respectively having outwardly facing surfaces at least one of which forms the sign carrying surface of the sign carrying element and inwardly facing surface which bound the tapered cavity and which are stepped or corrugated to cause light in the tapered cavity to be refracted and/or reflected through each of the facing surfaces and projected through the light conducting members to thereby evenly back illuminate the respective outwardly facing surfaces.
  • each of the two light conducting members have a profile which reduces in thickness away from the light receiving surfaces.
  • one of the light sources is located to project light through a non-sign carrying surface of the sign carrying element to illuminate a region about the sign carrying element.
  • the internal light source will be in the lower, one third of the sign carrying element and in the most preferred embodiment the light source is adjacent to the second edge of the sign carrying element.
  • the sign carrying element can take a number of forms including elements having opaque external structures, with light conducting members mounted in the structure, or alternatively, the body of the element can be transparent with the light conducting elements integrally formed and with masking and/or diffusing material applied in appropriate regions.
  • the sign carrying element is formed as a pair of half shells, moulded in translucent, high impact, plastics material, such as acrylic or poly-carbonate, surrounding a pair of lamps located at the upper and lower extremities.
  • the light transmitting region can be simply an opening or may incorporate a lens or diffuser.
  • the light source or sources will preferably be a fluorescent tube (eg, 8 watt fluorescent tube), or a cold cathode lamp, but could also include other light sources such as LEDs, incandescent lamps, neon lamps or any other suitable light source.

  • This arrangement allows the mounting and wiring unit to be wired into the building power network and a building safety services monitoring network with the electronics unit 18 removed, allowing easy access to mounting fasteners and wiring connectors. Subsequent connection of the electronics unit 18 provides an assembly in which dangerous voltages are shielded from probing fingers and access to internal electronics, or connection points is restricted by the need of a tool to disassemble the unit.
  • a sign carrier element 12 which is removable from the base unit 11.
  • the sign carrier 12 fits into a cooperatively shaped opening in the bottom of the base unit 11 and is retained by depressions or detents 22 and cooperating projections 23. Electrical connection between the removable sign carrier 12 and the electronic module 16 of the base unit 11 is via a pair of cooperating electrical connectors 24, 25.
  • the removable sign element 12 of the preferred embodiment is preferably formed in a transparent, semi-transparent or translucent material and is moulded as a pair of shell halves which when assembled together, encapsulate one or more light sources. The half shells are clipped together by cooperating clip elements 38 around the periphery of each half shell.
  • the shell of the sign element 11 encapsulates two light sources 26, 27, an upper one of which (light source 26) performs a normal sign illuminating function and the other of the two light sources 27, performs an emergency illumination function whereby the sign is illuminated, as well as a surrounding area of the floor under emergency conditions when the main lighting supply is interrupted.
  • the lower light source 27 can perform both functions, such that it is maintained illuminated under normal supply conditions and is switched over to the emergency supply when the normal supply is interrupted.
  • Wiring 28 to the light sources 26, 27 is run through channels 29 provided in the edges of the sign carrying element 12.
  • the light sources 26, 27 are located in the chambers 30, adjacent to the upper and lower edges of the sign carrying element 12 and transmit light into the body of the sign carrying element 12.
  • Light from the upper light source 26 shines down through a cavity 31 in the centre of the sign carrying element 12 and is coupled into the transparent plastics material of the sign carrying element 12, through the corrugated surface 32 of the cavity 31.
  • Light coupled into the material of the sign carrying element 12 back-illuminates a sign or signs located on one or both sign carrying surfaces 33.
  • the sign itself may either be screen printed (not shown) onto one of the surfaces 33, or may be a sign formed in a translucent film (also not shown), extending over the surfaces 33 of the sign carrying element and retained by tabs 34.
  • the lower lamp 27 projects light into the wall 35 of the two halves of the body of the sign carrying element 11, which act as light pipes, having multiple internal reflection modes.
  • light travels from the lower light source along each of the halves of the sign body and is subsequently refracted and reflected out of each of the body halves.
  • the light emerging from the outer surfaces of the body halves back illuminates the signs carried on the sign carrying surfaces of the respective body halves, while the light emerging from the inner surfaces of the body halves travels out across the cavity 31 and through the opposite walls 35 of the sign carrying element 12 to back illuminate the signs carried over the opposite outer surfaces of the sign carrying element.
  • light is refracted and/or reflected towards the respective sign carrying surfaces 33 by virtue of the corrugated surfaces 32 bounding the interface between the cavity 31 and the respective wall portions 35 of the sign carrying element 12.
  • the light sources 26, 27 are illustrated located in cavities at the upper and lower extremities of the sign carrying element 12, it is possible to move one or other of the light sources to an intermediate cavity in the sign carrying element 12 such as the cavity 40 illustrated in Figure 5.
  • the design of the corrugations 32 is designed to maximise coupling of light through the sign carrying surfaces of the sign carrier.
  • FIG 5 an alternative embodiment of the sign carrier is illustrated in which the lower lamp cavity 40 is located approximately midway between the upper and lower edges of the sign body and the modes of distribution of light in the lower portions of the sign body by the lower light source are similar to those previously described for the upper light source with reference to figure 4. Similarly the modes of distribution of light in the upper portions of the sign body of figure 5, by the upper light source, are also similar to those previously described for the upper light source with reference to figure 4.
  • a portion of the light from the lower light source 27 also projects through lower surfaces 37 of the sign carrying element to illuminate an area below the sign under emergency conditions.
  • the two light sources are not generally simultaneously operated.
  • the upper light source 26 providing a normal sign illuminating function during non-emergency conditions and the lower light source 27 operating under emergency conditions to illuminate the sign and to provide emergency lighting functions.
  • the light sources 26, 27 will typically be a high efficiency tubes that provide efficient use of battery power in emergency conditions.
  • the lamps will typically be 8w Fluorescent tubes, although other lamp types such as cold cathode tubes can also be employed. Switching between the operation of the upper light source 26 and the lower light source 27 will typically occur under control of the electronics module 16 which monitors mains voltage and switches over to a battery powered inverter circuit when failure of the mains supply is detected.
  • optional reflector elements 39 may either be formed as part of the sign body moulding or may be provided as an insert member. In either case the reflector elements 39 may inherently have reflective surface characteristics or may optionally be provided with a reflective material applied to their surfaces.
  • the channel 36 formed behind the reflector elements 39 carries wiring running across the top of the sign carrying element, and the reflector elements 39 provide a secondary function of protecting the wiring from heat radiated from the upper lamp 26.
  • the two lamps within the sign carrying element has the advantage that the lamps are separated from the electronics module, batteries etc.
  • the lower light source 27 is located remotely from the electronics and this enables the lamp to be substantially in thermal isolation, which in turn enables this lamp to remain operational for a significantly greater period than might otherwise be the case if located in closer proximity to the various heat generating elements of the assembly.
  • the shell of the sign carrier element 12 of the preferred embodiment is also openable once it has been removed from the base 11 such that tubes 26, 27 in the carrier 11 may be readily replaced. Removal of the sign carrier element 12 from the base 11 does not expose any dangerous surfaces and therefore may be performed by an unskilled person, as can the task of replacement of the tubes in the sign carrying element.
  • a further benefit of the removable sign carrier is that the sign carriers may be held in storage during building construction and the installation of the base units 11, to protect the sign carriers from damage. The sign carriers may then be installed after the more robust building activities have been completed. This also enables correct signage to be more easily located when installation takes place. Further, this operation can easily take place just prior to building hand over.
  • a further benefit of this arrangement is that lamp replacement can be performed at floor level, reducing the number of operations that need to be performed while the workman is standing on a ladder.
  • the sign carrying element may also be a sealed unit which is not capable of being opened to replace the lamps.
  • Such an arrangement has the advantage of high functional reliability by ensuring that inappropriate replacement lighting elements are not used.
