Description

DK 157419 B

The present invention relates to an illuminated eaves or eases, mainly suitable for use in the front yard of petrol stations and suitable for use as eaves with a marking of recognition by its illumination.

Illuminating traffic lights and illuminated troughs made entirely or partially of inorganic or organic glass in supporting profiles are already known. Such means are illuminated in a known manner by means of a series of light bulbs or by discharge tubes.

British Patent Specification GB-A-1,269,638 discloses an illuminated display sign, but not an illuminated eaves or eases, comprising a trough containing a fluorescent fluorescent tube mounted in a support. The known lamp is protected by a flat strip of translucent material which acts as a light diffusion element. Flat sidewall parts are located at the rear relative to the lamp as built-in parts and which provide light reflection. The known trough is closed by a flat panel of a translucent acrylic material and another baffle is hinged or removably attached to form a display surface.

The display signage known from GB-A-1,269,638 is not suitable for use on land and highways, as it is not free to dazzle, which causes road users when the light shines in the eyes.

There was a need for a distinct recognition mark for the wide edges of the gas station roofs.

For these reasons, the Dutch traffic authorities have issued regulations that these installations must comply with in light intensity to ensure safe traffic and at the same time fulfill the purpose.

Experiments have been carried out to investigate the way in which special traffic signs from gas stations and the like can be illuminated efficiently without the risk of traffic, and 35

2 finally, a construction has been invented which meets all the mandatory requirements.

It has been found during development that the known and commonly used systems for illuminating eaves' edges do not give a uniform light effect, that the colors and font become uneven and ugly under the influence of the sun's rays, electric lighting, heat, rain and wind. and that the usual way of mounting fluorescent discharge pipes always gave rise to 10 disturbances and errors due to wind and weather, whereby part of the lighting fades or the flickering or glare of the system arises in a very disturbing manner, and that the energy consumption in general is too high.

IS The aforementioned disadvantages can be remedied by a construction of an illuminated eaves and a lighting system according to the present invention.

In order to obtain a suitable brightness for the eaves, it is advantageous that the energy consumption of the pipes be chosen depending on the color desired, and since the energy consumption depends on the length of the pipes, rows of pipes of limited length are used in the system.

While conventional systems use 200 watts per meter, using the present system 40 W per meter. meters.

According to the invention, the illuminated eaves for use as eavesdroppers 1 comprise a cross-section rectangular trough containing a plurality of longitudinal axis cylindrical fluorescent tube lamps disposed in the respective footings, each lamp being protected only over the light-emitting portion of U-shaped sheaths clamped to the base of the tubular lamp, which sheaths are of a translucent plastic material and are closed at the contact ends, and at least one 35 flat reflective screen mounted in the trough in an inclined position behind the lamps, which trough is closed by a front panel of transparent plastic material to form a surface for a recognition mark. The position preferably forms an angle of 45 °

3 relative to the horizontal. In this construction you get absolutely non-dazzling traffic instructions for use e.g. petrol stations, which without visible glare are visible from a long distance, which is important for fast traffic.

5 Still, they do not bother the driver.

The translucent plastic material is preferably pole yearbonate which is sufficiently resistant to temperature changes and radiation effects.

10

Preferably, the front panel of the trough is a flat shield of weather-resistant polymethyl methacry 1 at.

On the front panel of the illuminated trough there may be color plates of transparent adhesive foil having a frosted surface as a recognition mark.

The light intensity of colored light depends on the color or wavelength.

20

Yellow light gives up to 350 Lux for the present use, but red light only gives up to 35 Lux.

The reflective screen preferably consists of several flat parts 25 of a smooth rectangular white material, such as a metal or impact-resistant plastic coated with white.

In accordance with the light intensities and the brightness, the screens must be placed in an oblique position of approx. 45 °, so that there will normally be greater intensity at the low side, but by placing the screens adjacent to a 45 ° angle, it is also possible to achieve the greater light intensity at higher, lower or centrally located parts of the eaves, if desired. 1

It is important that the contact ends of the tubes that do not emit light are not covered by the U-shaped sheath which protects the light emitting part of the tubes.

4 In this way, uniform translucency over the entire length of the series of fluorescent tubes will actually be achieved.

The construction according to the invention is explained in more detail below with reference to the accompanying schematic drawings.

In the drawings, FIG. 1-3 is a vertical cross-section of an eaves according to the invention; 4 is a horizontal cross section of the same structure; FIG. 5 shows a vertical cross-section of the light source in the form used in accordance with the invention; and FIG. 6 is a horizontal section of the sky alone.

The same reference numerals have been applied to all drawing numbers and the reference numerals mean the following: 20 1 are support profile light for a trough, 2 is an illuminated front panel, 3 is the underside, 4 are footpieces or holders with fluorescent tubular lamps 5, while 6 are U-shaped sheaths interrupted at regions 7, 8 are reflective screens behind the 25 pipes mounted in an oblique position at an angle of approx. 45 °.

The trough may have either one or two levels of screen planes 8, either at the upper or lower sides or to both sides. Long-term tests have shown that this roof-edge illumination does not dazzle and will remain visible at a reasonable distance so that it is noticed in time of rapid surveillance, and further that the lighting remains even, and is not prone to interference and bright light. 1 In alternative embodiments, the fluorescent tubular lamps 5 may be colored as needed, and the translucent U-shaped sheaths 6 may also be translucently colored, while the reflective screens 8 may be made of

15 One of the most obvious benefits of the system is the cost savings because only approx. 1/5 of the energy consumption of conventional fluorescence tubes. The construction of the invention is particularly suitable for gas stations, but can also be a practical solution for stores such as souvenir and stationery stores, bus and rail stations, airport offices, etc. Patent claims. 25 -------------------- Illuminated eaves for use as eaves, in a cross-sectional rectangular trough containing a plurality of longitudinal axis cylindrical fluorescent tube lamps (5) disposed in the respective footings (4), characterized in that each lamp is protected only by its light transmitting portion of U-shaped sheaths (6) clamped to the base of the tube lamp (4), which sheaths (6) are of a translucent plastic material and are closed at the contact teeth and that at least one flat reflective screen (8) is mounted in the trough at an inclined position of approx. 45 ° behind the lamps, which are closed by a front panel (2) of transparent plastic material to form a surface for a recognition mark.
