Abstract

A backlit meter comprises: a housing (10); a knob (21); a position dial (40); a main board (50); an optically transmissive ring (41) fixed to the housing (10); a light source assembly (44); a light-guiding board (45) disposed between the light source assembly (44) and the optically transmissive ring (41); a light-guiding post (22); and a backlight disk (30). The backlight disk (30) comprises a rotary disk (31) and an LED indicator (32) installed on the rotary disk (31). A connection through hole (211) is formed in the knob (21). The light-guiding post (22) is installed in the connection through hole (211). The position dial (40) is disposed on an outer surface of the optically transmissive ring. The invention enables normal use of an instrument meter even in a dark environment.

Description

technical field [0001] The invention belongs to the field of instruments and meters, in particular to a backlight instrument. Background technique [0002] In the prior art, instruments such as multimeters and clamp meters generally include knobs and gear dials, and the gear dials surround the knobs so that the knobs can indicate different scales when in use, and the instruments can perform corresponding functions. There is no backlight structure on the existing instrumentation, so that the operator cannot see clearly the position indicated by the knob on the instrumentation in a dark environment, which seriously affects the operation of the instrumentation by the operator, and finally makes it impossible for the operator to operate the instrumentation. Normal use of instruments and meters in dark environments. Contents of the invention [0003] The object of the present invention is to provide a backlight instrument, aiming at solving the problem that the existing instru...
