摘要： A direct-view lighting arrangement (24) suitable for the backlight of a liquid crystal display (LCD) (22) , comprising (in that order) an array of surface-emitting light sources (LEDs) (14) with an angular luminous intensity distribution, an array of beam spreading optical elements (28) , an array of Fresnel lenses (32) to reduce beam divergence and an (optional) diffuser (38). The refractive properties (convex and concave) of the beam spreading optical elements make the luminous flux essentially constant at the illumination plane (where the LCD is located). Thus, the beam spreading optical elements refract more light into higher beam angles thus compensating for the corresponding fall-off in luminous intensity of the sources. The thin sheet of Fresnel lenses reduces the divergence of the beams and directs them on to the diffuser. The (weak) diffuser serves to add a further beam divergence suitable for various applications, rather than itself producing uniformity in the illumination. The arrangement allows for a slimmer backlight design, eliminating the need for a strong diffuser having a high haze value (>90%). Keywords: Lambertian source,-illuminance,-luminance.
