ILLUMINATED FLUID LEVEL INDICATOR |
摘要 |
Lighting assemblies are provided for visual indicators which indicate the level of fluid in a container. One such assembly comprises a backlighting assembly (14) for a visual fluid level indicator (12) having front and rear transparent viewing windows (18) for viewing the level of a fluid contained therein, comprising: (i) a substantially flat fiber optic panel (34) located proximate the rear transparent viewing window; (ii) an attachment mechanism (36) for attaching the substantially flat fiber optic panel to the visual fluid indicator proximate the rear transparent viewing window; and (iii) an illumination source (31) optically coupled to the substantially flat fiber optic panel. The illumination source is a gas filled light source operating at less than 25 volts A.C. which is enclosed in a waterproof and explosion proo f enclosure (30), and which is optically coupled to the fiber optic panel by a fiber optic light cable (74). The lighting assembly may also be used for directly illuminating a magnetic fluid level indicator which indicates the level of fluid in a container (96) to which it is attached.
