摘要： The illuminator according to this invention consists of a rod adapted to transmit the light entering one end thereof to the other end, diffusion stripes, which are formed on the outer circumferential surface of the rod so that the diffusion layer extends continuously or intermittently in the axial direction of the rod, and which are composed of particulate bodies of a high refractive index, a transparent protective cylinder covering the outer circumferential surface of the rod with a clearance left between surface of the rod with a clearance left between the same outer circumferential surface and the inner circumferential surface of the protective cylinder, and a seal member for sealing both ends of the circumferential clearance between the rod and protective cylinder. The light transmitted from one end to the other is sent out in the direction in which the light crosses the axis of the rod, by the diffusion-reflecting effect of the diffusion stripes and owing to the functions of the rod as a lens so as to make the light function as the illuminating light. This light is not accompanied by heat, nor does it require consideration for electric wiring and electric insulation. Accordingly, the light is suitable for the illumination of a refrigerating showcase and the operation of a lighted advertisement.
摘要翻译：根据本发明的照明器由适于将进入其一端的光传输到另一端的杆，扩散条形成在杆的外圆周表面上，使得扩散层在轴向上连续或间歇地延伸杆的方向，由高折射率的微粒体组成，透明保护筒覆盖杆的外周面，杆之间留有间隙，间隙留在杆的表面之间，间隙留在相同的外圆周表面之间，保护筒的内周面和用于密封杆与保护筒之间的周向间隙的两端的密封构件。从一端向另一端透射的光通过扩散条的扩散反射效应，并且由于杆作为透镜的功能而沿光线与杆的轴线交叉的方向被发出，从而使光线作为照明光。这种灯不伴有热量，也不需要考虑电气布线和电绝缘。因此，该光适用于制冷陈列柜的照明和照明广告的操作。
