Claims (15)

  1. A light for a call point (10), the light comprising: a housing (22) having a light source; and a bracket (24) for supporting the housing (22) above a front surface (16) of the call point (10) such that the light source overhangs the front surface (16); the bracket (24) comprising a supporting flange (34) for securing the housing to the bracket; wherein the light source is positioned distally of a distal end of the supporting flange (34); the supporting flange (34) being positioned distally of the front surface (16) such that the supporting flange 34 partially overhangs the front surface (16) which allows the light source to illuminate the entire front surface (16) of the call point (10) with a uniformity of illumination of around 0.4 or higher.
  2. A light as claimed in Claim 1, wherein the bracket (24) comprises a pair of substantially vertical side arms.
  3. A light as claimed in Claim 2, wherein the bracket (24) further comprises an upper horizontal arm (39) and a lower horizontal arm (37) and wherein an aperture is defined within the vertical side arms and the lower and upper horizontal arms.
  4. A light as claimed in Claim 3, wherein the lower horizontal arm (37) comprises a gap such that the lower horizontal arm (37) is formed from a pair of arms.
  5. A light as claimed in Claim 4, wherein the pair of arms are coupled by a clip (94), the clip being moveable between a secured position in which the gap between the pair of arms is closed such that the pair of arms are secured relative to each other and an open position in which the gap between the pair of arms is open.
  6. A light as claimed in any one of Claims 2 to 5, wherein each of the pair of side arms comprise a tab for securing the bracket to the call point.
  7. A light as claimed in Claim 6, wherein each tab is aligned along a plane of the bracket (24) and wherein each tab extends inwardly towards the opposing vertical side arm along said plane.
  8. A light as claimed in any preceding claim, wherein the supporting flange (34) extends substantially perpendicularly from the bracket.
  9. A light as claimed in any preceding claim, wherein the housing comprises an aperture for conveying light from the light source and wherein the aperture is positioned distally of the distal end of the supporting flange.
  10. A light as claimed in Claim 9, wherein the housing comprises a lens and wherein the lens is aligned with the aperture such that light emitted from the light source passes through the lens prior to passing through the aperture.
  11. A light as claimed in any preceding claim, wherein the supporting flange comprises one or more retention formations extending laterally on the supporting flange for engaging a lower surface of the housing.
  12. A light as claimed in any preceding claim, wherein the housing (22) comprises a retention slot for receiving a fastener to secure the housing to the flange.
  13. A light as claimed in any preceding claim, further comprising a cover pivotally coupled to the housing (22).
  14. A call point comprising a light as claimed in any preceding claim.
  15. A method of fitting a light as claimed in any one of claims 1 to 14 to a call point, the method comprising: positioning the bracket (24) between a front panel and a rear panel of the call point; and securing the housing having the light source to the bracket; wherein securing the housing to the bracket (24) comprises moving the housing (22) relative to the bracket such that the light source is positioned distally of a front surface (16) of the front panel of the call point (10).

Description

TECHNICAL FIELD The present disclosure relates to a light for a call point. In particular, but not exclusively, the present invention relates to a safety light for illuminating the front surface of a call point. Aspects of the invention relate to a light for a call point, to a call point comprising a light and to a method of fitting a light to a call point. BACKGROUND Manual fire alarm call points are used to allow people within a building to raise the alarm if they discover a fire. As such, manual call points need to be prominently sited and easily accessed by a person in the event of a fire. Manual call points are distributed throughout buildings such that it is impossible to leave the building without passing a manual call point. Manual call points are typically located near exits from buildings or storeys within a building or on a thoroughfare within the building such that they are readily accessible in the event of a fire. Manual fire alarm call points are generally red in colour such that they are instantly recognisable as being a manual call point so that in an emergency situation a person within the building can quickly identify the nearest call point and raise the alarm. In order to help improve the recognition of manual fire alarm call points there has been a move within the industry to introduce regulations around the illumination of call points such that, even in the event of a power cut, the manual call points are clearly illuminated and easily identifiable to a person within the building. To meet the relevant safety standards emergency lights are often fitted on the ceiling in the vicinity of a manual fire alarm call point such that the emergency lighting can illuminate the call point in the case of an emergency. However, this solution is unsatisfactory as the illumination provided by the emergency lighting is often not sufficient to meet the safety requirements set within the standards. There is therefore a need to provide a solution to illuminate manual fire alarm call points to help make them instantly recognisable and identifiablo to a person within the building in an emergency situation. It is an aim of the present invention to address one or more of the disadvantages associated with the prior art. CN103218898 provides a manual fire alarm button with a video collection function and capable of flashing to alarm. SUMMARY OF THE INVENTION Accordingly, the present disclosure relates to a light for a call point as detailed in claim 1. Advantageous embodiments are detailed in the dependent claims. Furthermore, the present disclosure relates to a method of fitting a light as detailed in claim 15.

DETAILED DESCRIPTION In general terms embodiments of the invention relate to a light, for example an emergency light or a safety light for illuminating the front surface of a manual call point such that the call point is clearly visible and recognisable in an emergency situation. The safety light comprises a spacer bracket configured to be secured to the call point. For example, the spacer bracket may be secured between a front panel and a rear panel of the call point such that the spacer bracket can be retrofitted to existing call points. The safety light further comprises a housing attached to the spacer bracket. The housing comprises a light source for illuminating the front surface of the call point. Furthermore, the housing is secured to the spacer bracket such that the housing is located above and over-hanging the front surface of the call point. In this sense, the light source is typically positioned distally of a distal edge of the supporting flange. The safety light can advantageously be retrofitted to existing call points. When the safety light is fitted to call points the safety light illuminates the front surface of the call point thereby making the call point instantly recognisable in an emergency situation. Alternatively, the safety light may be fitted to new call points such that the call points are illuminated and clearly visible and recognisable in an
