Abstract

The invention is suitable for the field of devices and instruments, and provides a backlight instrument comprising a shell, a knob, a gear dial, a mainboard, a light-transmitting ring which is fixed on the shell, a light source component, a light guide plate which is arranged between the light source component and the light-transmitting ring, a light guide post and a backlight disc. The backlight disc comprises a rotating disc and an indicating LED lamp which is installed on the rotating disc. The knob is provided with a connecting through hole. The light guide post is installed in the connecting through hole. The gear dial is arranged at the external surface of the light-transmitting ring. The light guide post is arranged on the knob and the backlight disc is arranged in the knob so that light on the backlight disc can be scattered out through the light guide post; and the gear dial is arranged at the external surface of the light-transmitting ring, and light emitted by the light source component is scattered to the light-transmitting ring through the light guide plate so that the light guide post and the gear dial are enabled to be obvious in the dark environment, gear selection operation on the knob is facilitated, operators are enabled to normally use the devices and the instruments in the dark environment, and the beautiful effect of the devices and the instruments can be enhanced.

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...
