Description
Ref.:85-31. Can.Pat.Appl. 485 883.
Illuminated Canopy Ridge.
The present invention relates to an illuminated canopy ridge mainly to be used for the forecourt of petrol stations, and suitable as an eave-lath, forming a mark of recognition by its illumination.
Light beacons and illuminated troughs, partly or entirely made of inorganic or organic glass, in supporting profiles are already known;
such means are illuminated in a conventional way by a series of bulb lamps or by discharge tubes.
British Patent 1 269 638 discloses an illuminated display sign comprising a trough containing a fluorescent light tube mounted in a support.
The known lamp is protected by a flat strip of translucent material, which acts as a light diffusing element.
Flat side wall parts are located to the rear of the lamp as integral parts, giving reflection of the light.
The known trough is closed by a flat panel of a translucent acrylic material and a second front panel hinged or detachably secured to form a display surface.
There was a need for a distingulshable mark of recognition for the large ridges of the roo~s of petrol stations.
For these reasons the traffic authorities have issued regulations with which these installations should comply relating to the light intensity, with respect to the warrant of a safe road traf~ic and nevertheless to fulfil the purpose.
Experiments have been carried out to investigate in which manner the canopy roof ridges of petrol stations and the like along highways could be illuminated efficiently and yet without ha~ards for the traffic, and eventually a construction has been invented which complies with all obligatory requirements.
It has appeared in the course of the development that the conventional and usual canopy ridge illumination systéms do not bring about an even illumination, that the colours and~headings became unequal and ugly by the influence of sun rays, the electrical illumination, heat, rain and winds, and that the customary way of mounting fluorescent discharge tube lamps always gave rise to interferences and troubles as a result of the exposure to wind and weather, causing the dropping :
of parts of the illumination and glittering or flash-ing of the system in a very disturbing way, and that the energy consumption is usually too high.
These disadvantages could be overcome by a construction of the canopy ridge and illumination system according to the present invention.
For an appropriate luminosity of the canopy ridge it is advantageous that energy consumption of the tubes is selected depending on the colour desired, and since the energy consumed is dependent on the tube length, it is preferable that series of tubes of limited length are used in the system.
While in conventional systems 200 Watts per metre are used, the present system uses 40 Watts per metre.
The invention provides an illuminated canopy ridge adapted for use as an eave-lath. The canopy ridge comprises a housing of rectangular cross-section which contains a plurality of cylindrical fluorescent tube lamps mounted co-axially, each in a support. Each lamp is protected only over its light-emitting parts by a U-shaped cover which is clamped into the support.
Each cover is of translucent material and is closed at its end adjacent the contact ends of the tube it covers.
- 25 The canopy also includes at least one flat reflecting screen mounted in the housing at an angle to~the back wall of the housing. The housing is closed by a front p;anel of a transparent plastics material which is adapted to form a surface providing a mark of recong-~; ~; 3Q nltion.

- 2a -The reflecting screen is preferably mounted at an angle of 45 to the horizontal.
The translucent material is preferably poly-carbonate ("Makrolon", registered trade mark of sayer), which is sufficiently resistant against temperature changes and influences of radiation.
The front panel of the housing is preferably a flat shield of weather-proof polymethyl metacrylate ("Plexiglas", registered trade mark of Rohm & Haas, or "Perspex", registered trade mark of I.C.I.).
The front side of the illuminated panel can be provided with coloured planes of translucent adhe-sive film which provides a mark of recognition, having a matt surface.
Such indications, or mar]cs can adhere to acrylate glass better than to paint surfaces, and no stripping off o:E the letter-indications has been observed.
The light intensity of coloured light is dependent on the colour or wavelength of the light.

Yellow light f`or the present application yields up to 350 Lux, but red light only to 35 Lux.
The r~rlecting screen prererably consists of several flat parts ol` smooth rectan~ular white material, such as white coated metal or impact-resistant plastic.
In accordance with the li~ht intensities and luminosity the screens s~ ll be placed in ~n oblique positiorl of about 45 such that normally there will be a higher intensity at the lower side, but by positioning the screens adjacently with an angle of 45 it is also possible to obtain the higher light intensity at higher, lower or c~ntral parts of the c~nopy ridge, ir ~0 desired.
It is Or importance that the contact ends of the tubes which do not emit liKht are not cov~red by the said U-shaped cover, which is protecting the light-emitting parts of the tubes.
1~ Ln this manner an equal translucency over the entire length of the ~eries Or fluorescent tubes will be obtained in fact.

As alternative embodiments, the fluorescent tube lamps (5) may be coloured as required, and the translucent U-shaped covers (6) may be translucently coloured as well, while the reflecting screens (8) may be made of plain coloured material in order to intensify the coloured light if so desired.

For example, blue light may be used to "whiten" parts of an illumi-nated sign.
In the same way certain selected areas of the U-shaped translucent covers (6) may constitute filters responsive to liKht of preselected wave lengths.
One of the most spectacular advantages of the system is the saving of costs because only about 1/5 of the electrical energy of conven-tional fluorescent tube illuminations is consumed.
The construction according to the invention is particularly appro-priate for petrol tations but can also be a practical solution for shops, such as souvenir and stationary shops, bus stations, railway and air traffic offices, etcetera.
