Definitions

  • the present invention relates to an improved lighting system, in particular an improved system for providing street lighting.
  • street lighting is provided by means of a plurality of street lights, each comprising a lighting portion comprising one or more light emitters, often referred to as a luminaire, mounted on an elongate and generally vertically disposed column fixed to the pavement towards the side of a road.
  • a luminaire typically mounted on an elongate and generally vertically disposed column fixed to the pavement towards the side of a road.
  • Known luminaires incorporate two different means of attaching the luminaire to the column, so that they are adaptable to both of the types of columns shown in Figures la and lb respectively. In this way, personnel installing the street lights can select the most appropriate means of attaching the luminaire according to the type of column they are dealing with.
  • these known luminaires feature a changeable orientation portion, which must be accessed by personnel, removed from the luminaire and replaced with the correct type of orientation portion to match the design of the column to which it is to be attached (that is, either a column as shown in Figure l a requiring vertical entry of the column from below the luminaire, or a column as shown in Figure lb requiring horizontal entry of the column from the side).
  • known street lights often comprise some form of beam angle adjustment means whereby the angle of the light beam leaving the luminaire can be adjusted as required once the luminaire has been mounted on the column, in order that the correct area at ground level is adequately illuminated.
  • the beam angle adjustment means is normally located within the luminaire, and so in order to carry out the beam angle adjustment, the seal on the luminaire, which prevents the ingress of water into the luminaire, must be breached.
  • the bolts fixing the luminaire to the changeable orientation portion are first released whilst supporting the luminaire (which can sometimes weigh up to 12kg).
  • the angle of the luminaire is then adjusted relative to the column by various means including the selective meshing together of gears. Finally, the bolts are tightened once again whilst resealing the luminaire against the ingress of water.
  • the angle of the light beam leaving the luminaire is approximately adjusted first as described above to provide an approximately correct light beam path.
  • two personnel are required to return to the street light once the available daylight level is low enough to identify the illuminated area on the street below and finely adjust the beam path.
  • the street light must first be switched on in order to identify the illuminated area, and then electrically isolated to allow fine adjustment of the light beam.
  • the electricity supply is then reconnected and the luminaire is then switched on to verify the illuminated area and this process is repeated until the illuminated area is correct.
  • the luminaire must again be opened to access the beam angle adjustment means.
  • This beam angle adjustment process requires skilled labour both in terms of the manipulation of the beam angle adjustment means, which can be complicated, and the repeated electrical isolation at ground level during the adjustment process.
  • the aim of the present invention is to overcome, or at least alleviate, at least the above mentioned disadvantages of the prior art.
  • a lighting device mountable to a column fixed to the ground, wherein said lighting device comprises: - a lighting portion comprising at least one light emitter; and a mounting portion selectively attachable to said lighting portion and adapted to be attached to said column.
  • the lighting portion is to be connected to the column, it is only the mounting portion which is firstly required to be manipulated in order to attach it to the column and not the lighting portion (which is separately attached to the mounting portion once the mounting portion has been attached to the column) in addition.
  • This is a huge relief for personnel carrying out the repair or the upgrade, with the result that the work can be carried out much quicker than with known street lights and by one person as opposed to two.
  • a lighting device mountable to a column fixed to the ground, wherein said lighting device comprises a first portion including engagement means for engaging the column, said first portion being movable between a first condition in which the engagement means engages a horizontally extending portion of a said column, and a second condition in which the engagement means engages a vertically extending portion of a said column.
  • the lighting device comprises a lighting portion comprising at least one light emitter; and a mounting portion attachable to the lighting portion, whereby the first portion is movably mounted on the mounting portion.
  • the first portion is additionally movable to and from at least one further condition in which the engagement means is disposed so that the column is mountable to the lighting device by means of engagement of the engagement means with the column in a direction intermediate between the first and second conditions.
  • the engagement means comprises an elongate recess in the first portion.
  • the elongate recess is shaped so that a portion of the column can be disposed and retained therein.
  • the first portion is rotatable between the first and second conditions.
  • the mounting portion comprises a locking means adapted to lock the first portion in its first and second conditions respectively.
  • the locking means comprises a spring biased means disposed on the mounting portion, which selectively engages with either one of two corresponding portions on the first portion in order to selectively retain the first portion in its first and second conditions respectively.
  • the spring biased means comprises a first spring biased peg disposed on the mounting portion, which is selectively locatable inside either of two first holes formed in the first portion.
  • the locking means comprises a screw disposed on the mounting portion, which selectively engages with either one of two corresponding portions on the first portion in order to selectively secure the first portion in its first and second conditions respectively.
  • This provides the advantage that the orientation of the lighting device relative to the column can be carried out quickly and easily and without the requirement for tools, thereby enabling quick and easy accommodation of the different types of column currently in use. Moreover, there is no requirement to remove and replace different versions of components from the lighting device in order to carry out this orientation of the lighting device relative to different types of column, thereby saving time and effectively de-skilling the process. Moreover, there is no requirement to breach the waterproof seal which prevents the ingress of water into the lighting portion in order to carry out this orientation.
  • the first portion is adapted so that it rotates through approximately 180 degrees as it rotates between its first and second conditions.
  • the first portion is rotatably mounted on a rotationally symmetric bearing.
  • the first portion is rotatably mounted on a conical shaft mounted to the mounting portion.
  • the first portion rotates between its first and second conditions, it follows a conical path.
  • the axis of rotation of the first portion is disposed at an angle of approximately 45 degrees relative to the longitudinal axis of the lighting portion.
  • the first portion is rotatably mounted on a cylindrical shaft mounted to the mounting portion.
  • the lighting portion comprises a first electrically safe connector electrically connectable at one end to the light emitters and electrically connectable at the other end to a second electrical connector providing electricity to the lighting device.

  • the beam angle can be quickly and easily adjusted by personnel, without the requirement for any tools, in order to ensure that the correct area of ground is illuminated by the lighting device. Moreover, the adjustment of the beam angle can be carried out without breaching the seal that prevents the ingress of water into the lighting portion.

In having a smooth profile, this additionally provides a self-cleaning effect whereby rain is able to wash away any dirt which accumulates on the luminaire 3.
  • the present invention facilitates the quick and easy attachment of the luminaire to the column by means of orientation of the mounting portion with respect to the column and then the subsequent mounting of the luminaire to the mounting portion.
