1. A strip lighting device for receiving visible light from a source of illumination for illuminating the device with visible light comprising:
a main body having opposite front and rear sides extending along the length of the main body, the front side, in use, being disposed towards a viewer of the device, and the rear side including a light scattering layer for scattering light from said source of illumination towards the viewer when the device is illuminated; said main body including a front cladding layer and a rear cladding layer extending along the length of said main body, the front cladding layer being relatively forwards of the rear cladding layer relative to said viewer and said layers each being made of a first light transmissive material for conveying said light; and a light pipe arranged to receive light from said source of illumination and being made of a second light transmissive material for conveying said light, the light pipe being sandwiched between and in contact with the front and rear cladding layers at, respectively, a front interface and a rear interface, said interfaces extending along the length of the main body, the front interface being smooth to facilitate total internal reflection as light is conveyed along the light pipe and the rear interface including a plurality of angled portions spaced along the length of the light pipe to allow some of said conveyed light to escape from the light pipe into the rear cladding layer to impinge on the light scattering layer whereby the light scattering layer scatters said light though said light transmissive layers of the rear cladding layer, the light pipe and the front cladding layer towards the viewer of the device. |
