Definitions

  • This invention relates to lamp assemblies and a method of testing.
  • it relates to lamp assemblies of the type having a bracket which is secured to a wall or ceiling and a lamp body which can be easily and quickly fitted onto the connector.
  • GB-A-2194033 discloses a quick snap-on system for lamps in which a ceiling or wall mounted bracket is shaped so that a correspondingly shaped lamp body can slide onto the bracket, the lamp body and bracket being supplied complete with electrical connectors, the connection of which is made by virtue of the sliding action.
  • This type of assembly is useful for the removal and replacement of lamp bodies without requiring electrical connections to be rewired and re-made each time the lamp is replaced or removed, the connections being made automatically each time.
  • a lamp assembly according to the preamble of claim 1, characterised in that the assembly is such that the bracket and lamp body are arranged to mechanically connect before electrical connection is made, and in that the lamp body is arranged to slide relative to the bracket after mechanical connection has been made so that the electrical contacts of the PCB slide into and out of electrical connection with the bracket to make or break the electrical connection between the lamp body and the bracket.
  • the electrical connector for the lamp is formed by the existing printed circuit board.
  • the PCB may be slightly extended to form a tongue portion provided with a plurality of conductive fingers, connected to the circuitry on the board, and forming the pins of the connector.
  • the contact positions on the PCB may be reinforced by allowing a build up of solder, or by fixing additional conductive (eg. metallic) fingers or strips to the PCB.
  • the lamp body is located and latched onto the bracket by means of suitable locating means such as lugs, catches and guides so that a snap-on connection is possible.
  • the bracket and body are designed in this preferred embodiment such that the lamp body is first latched onto the bracket in a position where electrical contact is not made between the PCB and bracket connector but so that the body remains in position upon the bracket. The body can then be moved by a relative sliding motion with respect to the bracket such that the PCB slides into electrical contact and makes and electrical contact with the bracket.
  • the first mechanical connection is made between the two bodies at which electrical connection is not made and then electrical connection is made by a relative sliding movement to complete the connection.
  • the two stage connection is desirable for safety purposes and also for enabling easy testing. It is often a requirement that during installation of a system such as an emergency lighting system, the cables are tested for open and short circuits. Equipment which is commonly used to carry out such tests can damage delicate electronics in modern luminaires and so therefore testing is usually done after cables are positioned but before a luminaire is connected. This can be inconvenient.
  • the brackets can be fixed in position, the cables connected and the luminaires mounted in position at the first stage of connection but not electrically connected. The cables can then be tested (for example at the end of each cable run) and if the test is successful, then the lamp body can be electrically connected.
  • a locking means such as a screw, may be used to lock the luminaire body and bracket in position when it is electrically connected to maintain the PCB in contact with the connector and to stop unauthorised persons from disconnecting or removing the luminaire without the use of special tools for example.
  • Figure 1 shows schematically a lamp body 1 comprising a lamp 2 mounted within a cover 3.
  • the lamp may be of any type but will usually be a fluorescent tube type, with associated ballast and other apparatus 4.
  • a battery 5 will also generally be provided so that the lamp is powered by mains in normal operation and by the battery when mains power is disconnected.
  • the circuitry for the lamp is provided upon a printed circuit board (PCB) 6.
  • the printed circuit board is rigidly mounted to the luminaire body by mounts 7.
  • the printed circuit board 6 includes all or substantially all the relevant circuitry for the lamp and power supply, indicated by the area within dashed lines 8. It also includes a plurality of terminal connections 9 formed by printing conductive track extending to the edge of the board.
  • the tracks may be widened at their ends as shown to enable better contact to be made and the tracks make electrical contact with relevant parts of the circuit 8. Any number of terminal connections may be included as appropriate. In alternative embodiments, the board may be cut-away to form separate fingers for the terminal connections.
  • the conductive tracks may in some embodiments be reinforced by a build up of solder, or by fixing conductive (eg. metallic) fingers or strips thereto.
  • connections 9 on the PCB may be formed by other means or materials.
  • the lamp body also include mechanical connection means in the form of a slide connector 10 mounted generally at one end and a clip connector 11 mounted at the opposed end.
  • the design of these may vary widely and their function is described further below.
  • a co-operating bracket 12 is shown in Figure 3.
  • the bracket includes an electrical connector 13 which includes a longitudinal channel 14 such that the connector is U-shaped in cross-section.
  • the channel is provided, on its upper or lower surfaces, with a co-operating plurality of electrical terminals 15. These are designed to cooperate with terminal portions 9 of the printed circuit board and may be spring mounted by leaf springs or other means such that when the end of the printed circuit board bearing terminal fingers 9 is inserted into channel 14, the terminal connections 15 make good contact with finger portions 9.
  • the channel 14 should, of course, be of sufficient depth to receive the depth of the printed circuit board.
  • the PCB may be formed with a locating slot 6a at the end bearing the terminal connections, which co-operates with an equivalent lug or other means on the connector 13 to ensure correct spatial positioning thereof.
  • the channel may comprise a slot or be of other configuration.
  • the bracket further comprises a slideway 16 at one end, provided at one end with an opening 17 of sufficient width to allow slide connection 10 of the lamp body to enter.
  • a clip location 18 configured to receive clip means 11 of the body.
  • a slide channel 19 is provided to allow clip means 11 to slide with respect to the bracket.
  • FIGS 4 to 6 show the way in which the lamp body may be connected to the bracket.
  • the bracket is connected to a wall or ceiling, by means of screws or other means, and electrical connections are made between the connector 13 of the bracket and cables extending through or along the wall or ceiling as appropriate.
  • the lamp body 1 is brought towards the bracket 12 at an angle as shown such that slide locator 10 enters into opening 17.
  • Clip 11 is inserted into clip locator 12 and the lamp body is pushed downward into the position shown in Figure 5.
  • the connectors on the PCB 6 have not yet made electrical connection with connector 13.
  • the body is, however, mechanically connected to the bracket once it is pushed into the position of Figure 5 and will not fall out. It can only be removed by forcing clip 11 out of location 12 and tilting the base to remove it.
  • the lamp body is slid (to the left in the figure) such that PCB 6 partially enters channel 14 and the terminals 9 on its top or bottom edge make electrical contact with respective terminals 15 on the connector.
  • the slide connector 10 slides along slideway 16 to achieve this and clip connector 11 also slides along channel 19.
  • the lamp body reaches the position shown in Figure 6 in which an edge of the PCB has been inserted into channel 14 to make electrical contact, and the lamp may be operated.
  • the lamp body may be electrically disconnected by subsequently sliding to the right in the figure, freeing PCB 6 from channel 14.
  • a locking mechanism to prevent unauthorised or accidental disconnection.
  • This may be achieved by a screw 20, or by other means, inserted through the base of lamp body 1 into bracket 12 and optionally through bracket 12 into the supporting wall or ceiling.
  • This screw may require a special tool to remove it and serves to prevent relative sliding movement of the lamp body and bracket whilst it is present.
  • the clips 10, 11 and their complimentary engaging/sliding means 16, 17, 18, 19 are designed so that once in the position of Figure 5, the lamp body is generally mechanically fixed to the bracket, but can still slide to make or break electrical contact. Thus, the body can be moved out of electrical connection to enable testing, or component replacement, whilst still mounted on the bracket. Alternatively, clips 10, 11 can be pulled out of their respective engaging means on the bracket in a snap action to enable quick mounting/demounting of the body to/from the bracket.
  • Clip 12 may be provided with inwardly-directed resiliently mounted fingers 12a for example, the ends of which are forced apart by clip 11 when inserted or removed with a certain force greater than normal gravitational forces, retaining the clip when the lamp body hangs normally from a ceiling-mounted bracket but enabling the body to be forcefully pulled out when required.
  • Opening 17 may be of a size and shape that slide clip 10 can be inserted into it when inserted at an angle, as shown in Figure 4, but that slide 10 is held captive when it is angularly displaced to the angular disposition of Figures 5 and 6, with the lamp body generally parallel to the bracket.
  • the PCB 6 may be rotated into and out of cooperation with the channel 14, eg. horizontally.
