Claims

[Scope of utility model registration request]

An irradiator that irradiates each of the illumination surfaces of an indicator lamp from the inside, in which rectangular illumination surfaces having equal vertical dimensions and horizontal dimensions each approximately an integral multiple of the minimum dimension are combined in a box to form a total illumination surface. And,
It is formed as a rectangular frame-like body with a bottom surface having a through hole into which a light-emitting diode arranged on the surface of the printed wiring board is inserted, and a pair of opposing frame members of the frame-like body each extend toward the side of the bottom surface. a reflective frame forming a window-like engagement portion that engages with a protrusion of another member abutting the bottom back side; and a frame-like body bottom back surface that includes a protrusion that engages with the window of the engagement portion. a holder that is integrated with the reflective frame via the printed wiring board on the side to form an input voltage introduction part to the printed wiring board and that is fitted into a fixed position in the indicator light box body. , at least one of the windows of the engagement portion formed on the reflective frame with the minimum horizontal dimension and the protrusions formed on the holder are formed in multiple identical shapes at a predetermined pitch in the lateral direction of the illumination surface, and the windows and protrusions are A light emitting diode unit for an indicator lamp, characterized in that an engaging portion is formed to be movable at a predetermined pitch in the lateral direction of the illumination surface.
