An illuminator (1) is of elongate overall configuration, generally similar to that of a conventional illuminator of the fluorescent tube type. It 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). A circuit board (5) is supported on the housing (2), and it is a substrate for LEDs (6) and drive circuits (7). The housing body (2) has a supporting platform (9) for the PCB (5). 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. Each straddle bracket (30) comprises a top web (31) and two downwardly-depending flanges (32), forming together an inverted U-shaped configuration. On one side of a straddle bracket (30) a pair of receivers (35) together form a seat to receive a flange (27). Because of the angles at which the receivers (34, 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. |
