摘要： A luminaire (1) comprises an elongate structure (2) extending along a longitudinal axis, and a linear array of light emitting diodes (3) mounted on a substrate (10) and extending along the longitudinal axis. There are top reflectors (4) adapted to reflect light emitted by the LEDs to both transverse sides of the luminaire while blocking light in a region between the two transverse sides. The top reflector comprises a pair of longitudinal reflective surfaces (15, 16), one on each side of the longitudinal axis of the luminaire, and these surfaces (15) meet at an inner end at an apex pointing towards the diode. Also, there are transverse reflective surfaces (17) for deflecting emitted light substantially parallel to the plane of the substrate and away from the longitudinal axis of the luminaire. The luminaire is particularly suitable for illuminating a display cabinet, as it avoids need for two separate linear arrays of LED for illuminating for example above and below a product shelf.

摘要： A luminaire (1) comprises an extruded aluminium housing (2) which is generally L-shaped, with a web forming a base (3) with an integral platform (4) supporting an LED substrate (5). The latter supports a linear array of LEDs, namely a series of LEDs (6) along a front side, and a drive circuit 7 along part of a rear side. A planar elongate rectangular reflector (14) is supported on a series of cradles (10) on the substrates (5). Each cradle (10) comprises a pair of aligned clips of Cu material. The top of the reflector (14) has a lip (16) which is turned in the direction over the circuit (7) to engage the housing (2) to be retained securely in place. The housing (2) also includes a web forming a rear wall (8), so that the housing (2) forms a generally L-shaped configuration in end view. The reflector (14) is at an obtuse angle to the substrate on the LED side. This provides comprehensive reflection of light in the space directly above the LEDs, weighting the light emission in this direction. It is particularly suited to illumination of a goods display plane, either vertical or horizontal, in a retail cabinet. Because the directionality is achieved by a mirror which is beside the LEDs and below the diffuser there is excellent directionality as viewed in end view (Fig. 7) and at the same time excellent diffusion for uniformity along the length dimension.
