An electronic device of the present invention includes: a stacked body including at least one columnar stacked unit that is stacked in a first direction and accommodates an electronic component; a lid member attached to an end-portion stacked unit provided at an end portion in the first direction of the stacked unit, and having a top wall portion and a side wall portion extending from a peripheral edge of the top wall portion; and a ring-shaped gasket attached between the end-portion stacked unit and the lid member, in which a ring-shaped attachment groove for accommodating the gasket is formed on an outer peripheral surface of the end-portion stacked unit, the attachment groove has a first surface on the lid member side in the first direction, a second surface on a side opposite to the first surface in the first direction.

Electronic device and gasket

An indicator light () includes a light source, a lens (), and a cylindrical globe (). The light source includes a center LED (A) disposed on a disposition surface parallel to a central axis (C) and having an optical axis perpendicular to the disposition surface and a pair of side LEDs (B,C). The lens includes a central lens portion (A) and a pair of side lens portions (B,C). The central lens portion emits light to a central radiation angle range (A) centering on a central light-emission reference line (L) along a reference normal line (BN) of the disposition surface. The pair of side lens portions (B,C) emit light to a pair of side radiation angle ranges (A, A), respectively, that contain a pair of side light-emission reference lines (L, L), respectively, that are inclined mutually-opposite directions at an inclined angle of 60&#xb0; with respect to the central light-emission reference line (L). The central lens portion includes a central light incidence portion () having a central incidence surface () on which light from the central LED is made incident and a plurality of central light guiding portions () that branch from the central light incidence portion in the shape of branches and that extend toward the globe side. In each of the central light guiding portions, light that has been refracted and has been made incident from a corresponding incidence region of the central incidence surface onto the corresponding central emission surface is refracted and emitted from the corresponding central emission surface toward a corresponding region of the central radiation angle range.

Indicator light

When viewed in parallel to a central axis (C), three LED substrates () form an equilateral triangle (T) that surrounds the central axis (C) and are disposed equidistantly with respect to the central axis (C). When viewed in parallel to the central axis (C), LEDs () are disposed on an outer surface () of each LED substrate () at least one each at each of a pair of placement positions (Q) at both sides sandwiching a reference normal (BN) being a normal to the outer surface () and passing through the central axis (C). The LEDs () each have an optical axis () orthogonal to the outer surface (). When viewed in parallel to the central axis (C), radiated lights from the LEDs () at the pair of placement positions (Q) of each LED substrate () are, by an optical system (K), converted to and emitted as emitted parallel lights (RPL) that are respectively parallel to a pair of light emission reference lines (RB) passing through the central axis (C) at both sides sandwiching the reference normal (BN) and respectively contain the corresponding light emission reference lines (RB).
