    Description of the Embodiments



    [0037] Referring to the drawings an illuminator 1 is of elongate overall configuration, generally similar to that of a conventional illuminator of the fluorescent tube type. The illuminator 1 comprises a housing body 2 which is a section of a length of extruded aluminium. A transparent polymer cover 3 is snap-fitted in place across a front opening of the housing body 2. There is an end cap 4 at each end of the housing body 2, secured in place by screws into the end faces of the housing 2.

    [0038] A circuit board 5 is supported on the housing 2, and it is a substrate for LEDs 6 and drive circuits 7.

    [0039] As shown most clearly in Figs. 3(a) and 3(b) the housing body 2 has a supporting platform 9 for the PCB 5. A channel 10 runs centrally along the length of the housing body 2, acting as a guide and receiver for screws 11 to secure the PCB 5 to the housing body 2. The channel 10 comprises ridges along each side, allowing secure engagement of the screw threads. There is a heat transfer pad 18 between the board 5 and the housing platform 9, allowing optimum thermal contact. Alternatively, there may be a different thermally conductive material such as thermally conductive greases or rubber. If there is a pad, it may have an adhesive.

    [0040] This arrangement presses the board 5 against the housing 2 so that there is optimum heat transfer from the underside of the board 5 into the housing 2. It also allows the illuminator to be easily assembled during manufacture, and for the PCB to be removed and replaced for any maintenance or upgrade that may be required during its lifetime. Also, there is no need for pre-drilling in the housing 2 for the screws 11 as the channel 10 provides a sufficient guide for engaging screws at any position.

    [0041] The housing 2 comprises a base 12 for physical support of the board 5, for overall strength, and for heat transfer. Heat transfer pads 18 and integral fins 13 complete a heat transfer path to the surrounding environment. The edges of the fins are rounded to avoid sharp edges.

    [0042] The housing body 2 also comprises longitudinal grooves 14 on each lateral side at the front for retaining the transparent cover 3. Because the cover is flexible, it can be easily snap-fitted into position. This allows the cover 3 to be easily fitted during manufacture and to be fitted and removed during the lifecycle of the illuminator. In another embodiment, there is less flexibility in the cover.

    [0043] It will be appreciated from Figs. 3(a) and 3(b) that the internal surfaces of the housing surrounding the PCB 5 will reflect some light from the LEDs 6, thus optimising the extent of light output and also allowing significant control over the directionality of the light according to the shape of the housing 2. The shape of the housing may be different from that illustrated in order to achieve a different light output pattern with a different extent of reflection from the internal surfaces.

    [0044] Fig. 4 shows an end cap 4 in more detail. It will be noted that there is a ledge 15 for additional support of the board 5, fixing screw apertures 16, and an aperture 17 for electrical cable 20 for the board.

    [0045] It will also be appreciated from the drawings that the illuminator may be manufactured with excellent versatility in terms of its length. One must only cut the extruded aluminium housing body 2 to the desired section length and cut the plastics cover 3 accordingly. The PCB 5 is in modular sections with terminals for interconnection. Indeed it is envisaged that the illuminator may even be customised on site to suit the display case into which it is being fitted.

    [0046] Referring to Fig. 5 the illuminator 1 also comprises mounting couplers 25 secured by grub screws. Each coupler 25 is of tubular shape, and at its outer extremity there is a circumferential groove 26 defining an end flange 27. The cable 20 is trained through the coupler 25.

    [0047] The couplers 25, together with straddle brackets 30, allow the illuminator to be easily and securely mounted onto conventional shelf supports or brackets B, for retrofitting or original installation. As shown in Figs. 6 to 8 inclusive each straddle bracket 30 comprises a top web 31 and two downwardly-depending flanges 32, forming together an inverted U-shaped configuration. The flanges 32 have corresponding vertical slots 33 to accommodate the cable 20. Also, there is a pair of receivers 34 and 35 on each flange 32, together forming a seat. Each receiver extends at an angle between vertical and horizontal tapered downwardly towards each other. Each receiver 34, 35 comprises a pressed-out length of the bracket metal forming a slot to receive the end flange 27.

    [0048] Referring to Figs. 9, 10, and 11 on one side of a straddle bracket 30 the pair of receivers 35 together form a seat to receive the flange 27 of a coupler 25. Because of the angles at which the receivers 34 and 35 are inclined they form a particularly stable seat for the ends of the illuminator 1, and furthermore they allow the illuminator to be rotated for optimum direction of the light. The illuminator further comprises a fixture which is secured to the shelf support B by engagement of a pin in an aperture of the shelf support. This is secured in place at a location to prevent sliding of a straddle bracket 30.

    [0049] It will also be appreciated that the sleeve-shaped couplers 25 and the straddle brackets 30 allow the illuminator to be easily and quickly mounted in a display cabinet having conventional shelf supports or brackets B, allowing very easy retrofitting. What has been achieved is excellent illuminator support stability, versatility for rotation to a desired illumination direction, and very simple fitting/installation either retrofitted or original. Fig. 11 in particular shows how the top web 31 of the bracket 30 is matched in height by a fixture 40 over the shelf support B to ensure horizontal mounting of the shelf S.

    [0050] The illuminator, when installed, can be rotated to any desired orientation so that it may for example illuminate items on a shelf underneath it. Alternatively, it may be upwardly directed to illuminate items above it through a glass shelf supported on the shelf support brackets.

    [0051] Another advantage of the illuminator is that the manufacturer can easily choose illumination parameters by simply choosing the desired configuration of modular boards 5. For example, there may be a specific chosen pattern of different LEDs to achieve a particular illumination effect. Another versatile parameter is the length of the housing body 2, and hence of the illuminator.

    [0052] It will be appreciated that the illuminator has a similar physical configuration to a conventional fluorescent illuminator, allowing the latter to be replaced with illuminators which do not give rise to hazardous waste disposal issues. Indeed, it is envisaged that, in another embodiment, the illuminator may be configured to fit into a support and power supply of a conventional fluorescent illuminator. Thus the illuminator may be supplied as a plug-in replacement for a fluorescent tube, with the fluorescent tube electrical supply providing power to the circuit. The power supply may be mains or down-converted AC or DC depending upon the illumination requirements. This embodiment may include a safety feature for by-passing or disconnecting a ballast to ensure that high voltages are not applied.

    [0053] In use; it is preferable that a pair of opposed straddle brackets 30 supports an illuminator, however with suitable configuration of the brackets and couplers (and possible size and weight of housing) a single straddle bracket may provide cantilevered support. This allows further versatility.

    [0054] It is also envisaged that the illuminator may form part of a frame of a display case, such as a mullion.

    [0055] Referring to Figs. 12 and 13 in another embodiment a bracket 50 has a U-shaped shelf edge surround 51 for straddling the front edge of a shelf S and a screw 52 to secure the bracket 51 in place. The lower flange of the surround 51 is secured to a depending and circular illuminator support 53 through which the illuminator coupler 25 fits. Again, this allows the illuminator to be easily retro-fitted to an existing cabinet, and to be rotated to an optimum illumination position.

    [0056] In a further embodiment, an illuminator support may have a bracket similar to the bracket 50, but the support means may be similar to the arrangement in the bracket 30, with opposed cut-outs or grooves forming a seat for the ends of the illuminator.

    [0057] The invention is not limited to the embodiments described but may be varied in construction and detail, within the scope of the appended claims.
