Description

IMPROVEMENTS RELATING TO STREET LAMPS
This invention relates to street lamps.
In this specification the term street lamp is used broadly to include street lights, road lights, motorway lights as well as other lighting such as for road signs and in pedestrian areas.
In conventional street lamps, the light source is carried high up on a column or standard. With such a lamp, the light source or lantern, in the form of a bulb or tube, is virtually inaccessible without special equipment. Thus replacement of the lantern or general maintenance is a considerable job. Often, for maximum effect, the light source overhangs the road or street, and so a lorry with a lift platform is necessary. At best this is a nuisance which may lead to traffic congestion and it can be positively hazardous.
Accordingly, 'in one aspect, this invention provides a street lamp comprising a column with a light source located in the lower end region of the column. Thus, if the light source fails, the base of the column can be opened up and a replacement quickly and easily fitted, by one man.
The street lamp preferably includes a bracket or arm at the upper end of the column which has a light outlet for directing light generally downwardly, and the bracket or arm may include light guide means for deflecting light received at an inlet end thereof towards said light outlet.
In one example, the light guide means comprises an internal reflective surface within the arm or bracket, and the internally reflective surface may be a metal plated or polished internal surface of said bracket or arm.
In another example, the light guide means comprises one or more optical fibres.
The upper end of the street lamp may be configured in different ways depending on the particular application. For example the bracket or arm may be bifurcated or branched to supply two or more light outlets .
In some applications the or each light outlet may be angularly adjustable to vary the projection of the light emitted thereby.
The light source preferably emits a beam of pencil form which passes upwardly through the interior of said column to be incident on said light guide means. Preferably, the beam passes through free space, but in some applications it may pass upwardly through a light guide such as a bundle of fibres. Advantageously, the light source is mounted in an assembly within the base of said column, said bracket allowing adjustment movement and/or light source replacement.
When lighting is also required for the pavement or for a road sign adjacent the street lamp, the column may include tap means intermediate the ends of the column for directing a portion of the output of said light source to the exterior of the column.
The tap means may include an outlet lens or window generally flush with the outer surface of the column. It may include a prism or other deflecting element for intercepting a portion of the light passing up the column. Alternatively, light may be supplied to the lens by an optical fibre. The or each light outlet preferably includes a head having an internal reflective surface for directing the light to pass through a lens or window. The internal reflective surface of said head may be formed by a metal plated or polished inner wall surface of the head.
In another aspect, this invention provides a bracket or arm for being fitted to a column having a light source in its base or lower end, said bracket or arm comprising an inlet end for attachment to the upper end of said column, a light outlet, and light guide means for deflecting light from said inlet end towards said outlet end. The light guide means may for example be a reflective surface or one or more optical fibres. The invention may be performed in many ways and an embodiment thereof, and several modifications will now be described by way of example only, reference being made to the accompanying drawings, in which:-
Figure 1 is a schematic view of a street lamp in accordance with the invention;
Figure 2 shows a section view of part of the base of the street lamp of Figure 1, showing the lantern mounting assembly;
Figure 3 shows a modified form of bracket for the lamp of Figure 1;
Figure 4 is a detailed view of a light "tap" on the column of the lamp of Figure 1.
Referring to Figure 1 a column 10 is anchored in the ground and has an arm or bracket 12 secured to its upper end. The base of the column 10 has an access door 14 behind which is located a light source comprising a lantern 16 and an associated reflector 17 adjustably mounted in an assembly 18. The light source projects a well defined pencil beam 20 through the centre of the column.
As seen from Figure 2, the assembly 13 allows the lantern 16 to be positioned for the correct projection and also allows the lantern and the reflector to be hinged horizontally to allow replacement of the lantern. Two clamp wheels 15 riding in slots in a subframe 19 allow the lantern and reflector to be adjusted vertically and hinged.
The beam 20 passes into the inlet end of the bracket 12 and is deflected to the light outlet or head 22 which directs the light where it is needed. In the example shown in Figure 1, the light is deflected along the bracket by the highly reflective internal surfaces 23 of the bracket 12. The reflective surfaces may be achieved for example, by plating with a metal such as chromium or by polishing.
The head 22 includes suitable means for directing the light. For example as shown, the head may include a reflector 24 which deflects the beam through a diffuser 26 or other lens or window. Alternatively, the interior surface 25 of the head 22 may be made reflective and this may obviate the need for the reflectors 24.
The principle of the above example may also be applied to street lamps with more than one head, i.e., to street lamps having two or more arms each supporting a head or having a cluster of heads disposed around the column. Figure 3 shows an example of this, where the column supports a bifurcated bracket 28. Each limb 29 of the bracket supports a head 22 and, in this example, the light is supplied from the column to each head by a bundle 30 of optical fibres. The limbs could instead have internal reflecting surfaces as previously. To allow for adjustment of the orientation of the heads 22, the limbs 22 are articulated at 32. This arrangement may allow the overhang associated with many street lamps to be reduced, thus saving in cost and improving the stability of the lamp.
In many instances it would be useful to be able to tap off a portion of the light from the light source for other purposes, for example to provide pavement lighting for a road sign.
Figure 4 shows how this may be achieved in a modified form of the arrangement of Figure 1. The column is provided with a horizontal slot 34 passing part-way around the circumference of the column, at the required level for the particular application. An arcuate prism 36 is housed in the slot with one surface flush with the outer surface of the column. An inner portion of the prism 36 protrudes part way into the pencil beam and taps off a portion of the light and deflects it in the desired direction. Clearly the design and location of the prism can be selected as required.
For control and switching of the street lamp, it may include a photoelectric cell (not shown) in the base of the column which operates a relay or other trigger circuit to switch the lantern 16 on and off as required. Alternatively, a series of street lamps may be wired to a single control box. The control box may include a photoelectric cell for controlling the switching. However, it is preferred for the control box to be signalled remotely by means of a signal supplied to it, for example by a code impressed on the mains voltage supplied to the control box. This form of control allows the use of computerised grid lighting control, in which the comnuter centre programmes the timing "on and off" facility on a flexible basis within variable periods of time and eliminates the need to employ photoelectric cells.
The various examples above provide ease of servicing and maintenance from ground level. There is a cost saving because it is not necessary to run an electric cable from the base to the head.
