Definitions

  • the invention which is the subject of this application is a Halogen light unit and means of converting a standard light fitting into a Halogen light unit, and particularly, but not exclusively, improvement to a light fitting of the type used in underwater environments such as in swimming pools and the like.
  • the lights used for underwater fixings such as in the walls or floors of underwater environments such as swimming pools conventionally comprise a recess or aperture in the wall or floor or a panel forming the same, a housing which fits into the recess and forms a waterproof electrically connected housing into which an inner housing with a lamp known as a Par Lamp which comprises an outer lens, sealed to a back plate in which is housed the bulb and a reflector is fitted, to form the light unit.
  • the Par Lamps typically include a 300 watt element of the conventional type.
  • Halogen light bulbs are a relatively recent development and there are advantages to be gained by using the same.
  • One advantage is that the life of the bulb is longer than conventional bulbs and this provides savings in the number of bulb replacements required and also in the number of times the light fittings have to be accessed to replace the bulbs, which, when one considers that the light fittings are under water, can be time consuming and expensive.
  • a further advantage is that the power consumption of halogen light bulbs is considerably less than with conventional light bulbs and can be a third of the power consumption of the conventional bulbs. This therefore means that the running costs of the lights are considerably reduced and that the lights run at lower temperatures and therefore reduce the risk of overheating as with the conventional lights which are required to be cooled by the water in which they are positioned.
  • halogen light bulbs should be used but at the present time, in order to use the same it is necessary to remove and discard the existing Par lamp unit and inner housing and then purchase new, relatively expensive, halogen lamps and inner housings and then fit the same in the wall or floor recess of the swimming pool. This expensive operation therefore tends to negate the advantages which can be obtained from using halogen light bulbs.
  • Another alternative is to remove the Par lamp, place a glass plate over the inner housing opening and then mount the halogen bulb from the rear of the inner housing but this is again time consuming and expensive to achieve.
  • the aim of the present invention is to provide a means for converting existing conventional light units so that the same can be formed into a halogen light unit and obtain the desired advantages while minimising the time and cost to do so.
  • a halogen lamp unit for underwater use, said lamp unit comprising a housing formed from a lens at the front and a back plate and mounted within the housing a reflector and a light bulb unit characterised in that the light bulb unit incorporates a halogen light bulb in a holder held in position by retaining means in engagement with the back plate and means allowing connection with the electricity supply with the lamp unit held in sealing engagement with a light fitting.
  • the halogen lamp unit is typically formed with the same external diameter as the conventional Par lamp, i.e. to allow the same to be fitted into the light fitting into which the Par lamp fits. It is also preferred that the halogen lamp unit is shaped so as to be able to lie within the fitting and form a seal with sealing means provided on the fitting so as to prevent contact between the water and electrical connections.
  • the halogen bulb unit typically includes retaining means which comprise a plate which locates in a similarly outlined aperture in the back plate of the lamp and said unit is releasably engaged with the back plate to allow removal and replacement of the bulb.
  • the bulb unit typically also includes a shield mounted to the front of the bulb to obtain the required pattern of light.
  • the Halogen light bulb unit incorporates the light bulb with connecting pins held in contact with a connecting socket and said socket and bulb are formed as an integral unit with connection leads depending therefrom. This means that the bulb unit can be placed and secured in position in the lamp unit without the need for the bulb to be directly electrically connected. All that is required is for the connecting leads to be connected to the external electricity supply. This makes the connection of the halogen light bulb unit significantly easier than is conventionally the case where the light bulb is required to be pressed into the socket to connect the pins with the socket.
  • a method for converting a Par Lamp light unit to a Halogen light unit by the method of removing and disconnecting the Par lamp unit from the existing fitting or mounting of the conventional light unit and replacing the same with a Halogen lamp unit with a halogen light bulb unit fitted therein and said lamp unit of a shape to allow the same to fit in the existing fitting and form a seal with the same and electrically connecting the same to form the halogen light unit.
  • This method allows the existing light unit mountings and housings to be continued to be used for the halogen lamp unit and therefore represents considerable time and cost savings.
  • the halogen bulb is releasably mounted via engagement means with the back plate of the lamp unit to allow removal and replacement of the same.
  • the lamp 2 comprises a front lens 4, sealed to a back plate 6 to form a housing.
  • the inside face of the back plate is formed with material to act as a reflector 10 and there is also mounted in the housing a shield 12 which is mounted to lie to the front of the Halogen bulb 16 as shown in Figure 1B.
  • the Halogen bulb is provided as part of a light bulb unit 18 shown in detail in Figure 1D which comprises the light bulb 19 held in a holder 21 which includes connecting pins 23 in connection with a socket 25 and formed as an integral unit with connecting wires 20 so that only the wires 20 need to be connected to the electricity supply and the bulb is already inserted and provided as an integral part of the bulb unit to make the fitting of the same easier in situ.
  • the holder 21 also includes a plate 24 which is formed with location indents which match with protrusions formed on the aperture 22 in the back plate 6 to ensure the correct orientation of the light bulb in the housing.
  • the light bulb is retained in position by engagement means 26 which engage in location with the back plate to lock the bulb in position.
  • the engagement means 26 can be selectively released to allow changeover of the bulb as required.
  • Figures 2A-2B illustrate the manner in which the halogen lamp of Figures 1A and B can be fitted to convert an existing light unit to a halogen light unit.
  • Figure 2A illustrates a convention Par lamp 40 connected via cable 42 to an electricity supply 44 to the rear of a wall 46.
  • the lamp 40 is shown with a front clamping ring 41 and is mounted in a fitting which in this form is an inner housing 48 which is in turn located in an outer housing 49 which is fitted in the wall.
  • the Par lamp is normally positioned in the inner housing and forms a seal with an o-ring 51, as shown in Figure 2B which is a cross section through the inner housing, which prevents the water which surrounds the front of the lamp unit to cool the same, from passing to the electrical connections 43.
  • front clamping ring 41 is removed from the inner housing 48 as shown by arrow 50 in Figure 2A.
  • the electrical connections 43 are disconnected and the lamp unit 40 is removed.
  • the same is then replaced with a halogen lamp 2 of the type shown in Figures 1A-1D with the electrical connections 20 connected to the cable 42.
  • the lamp 2 is then placed into position in the inner housing 48 and as it is provided to lie in the same area as the lamp unit 40, forms a seal with the o-ring 51 without the need for any alteration of the inner housing 48.
  • the present invention provides a means whereby existing light unit fittings can be used and converted to halogen light units by the removal of the existing lamp unit and introduction of a halogen lamp unit in accordance with the present invention. This allows the advantages of using Halogen lamps to be obtained while minimising the costs of installing the same.
