    摘要： A lens component includes: a light incident portion (16) having an incident face (14) upon which light from a light source (6) is incident, the light source (6) being disposed at a light source position (15); and a plurality of plate-like light guiding portions (17, 32) disposed radially around an axis (S0) passing through the light source position (15) or a position in the vicinity thereof, and arranged to guide light incident from the incident face (14) of the light incident portion (16), in emission directions (F, F1-F3) at right angles to the axis (S0). Each of the plate-like light guiding portions (17, 32) is provided on an end face (27) thereof with a radial reflecting face (29, 29A, 29B) for internally reflecting, in the emission directions (F, F1-F3), the light incident from the incident face (14) of the light incident portion (16). Further, each of the plate-like light guiding portions (17, 32) has a pair of main surfaces (25) forming a pair of light guiding and reflecting surfaces which extend substantially in parallel to the predetermined axis (S0) and which guide, as internally reflecting, the light incident from the incident face (14) in the emission directions (F, F1-F3).

    摘要： A signaling lamp including a hollow cylindrical supporting column made from a light-transmitting material which has a central portion bulged outwardly so that the interior surfaces are made into reflective surfaces. LEDs are arranged in rows so as to face each other above and below the reflective surfaces, and the supporting column and the LEDs are surrounded by a globe which has diffusing lenses. The light from the LEDs is reflected toward the circumference by the reflective surfaces and is projected into the surrounding area via the globe.

    摘要： When viewed in parallel to a central axis (C1), three LED substrates (4) form an equilateral triangle (T) that surrounds the central axis (C1) and are disposed equidistantly with respect to the central axis (C1). When viewed in parallel to the central axis (C1), LEDs (8) are disposed on an outer surface (4a) of each LED substrate (4) at least one each at each of a pair of placement positions (Q1) at both sides sandwiching a reference normal (BN) being a normal to the outer surface (4a) and passing through the central axis (C1). The LEDs (8) each have an optical axis (8a) orthogonal to the outer surface (4a). When viewed in parallel to the central axis (C1), radiated lights from the LEDs (8) at the pair of placement positions (Q1) of each LED substrate (4) 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 (C1) at both sides sandwiching the reference normal (BN) and respectively contain the corresponding light emission reference lines (RB).
