<p>The embodiment of the present invention relates to a working state indicating device which comprises a housing; an indicator light accommodated in the housing; a reflective part accommodated in the housing for reflecting the ray of light emitted by the indicator light; and a printed circuit board accommodated in the housing, wherein the indicator light is arranged on a panel on the side of the printed circuit board adjacent to the reflective part, a through-hole is arranged on the printed circuit board, and the ray of light emitted by the indicator light and reflected by the reflective part, passes through the through-hole and then exits through the housing. The working state indicating device provided by the embodiment of the present invention effectively prevents the generation of a halo around a light guide part by means of covering peripheral divergent light sources with the printed circuit board.</p> |
