Abstract: A level meter includes light emission segments forming an emission region, a register portion to register a default emission condition and an emission-condition specified value, and a control portion. The control portion controls the light emission so that the emission region spreads in an emission proceeding direction according to an increase in numerical quantity to be expressed. An emission-condition specified value indicates a command to apply a predetermined specified emission condition concerning a subsequent segment positioned on a more upstream side than a foremost segment positioned on a most downstream side in the emission proceeding direction. The control portion allows all the light emission segments forming the emission region to emit light based on the default emission condition, and the control portion allows the foremost segment to emit light based on the default emission condition whereas allowing the subsequent segment to emit light based on the specified emission condition.

Abstract: An indicator light (1) includes a light source, a lens (4), and a cylindrical globe (5). The light source includes a center LED (2A) disposed on a disposition surface parallel to a central axis (C1) and having an optical axis perpendicular to the disposition surface and a pair of side LEDs (2B, 2C).

The central lens portion emits light to a central radiation angle range (A1) centering on a central light-emission reference line (L1) along a reference normal line (BN) of the disposition surface. The pair of side lens portions (2B, 2C) emit light to a pair of side radiation angle ranges (A2, A3), respectively, that contain a pair of side light-emission reference lines (L2, L3), respectively, that are inclined mutually-opposite directions at an inclined angle of 60° with respect to the central light-emission reference line (L1).

Abstract: 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).

Abstract: A lens component disperses light from a source having a distribution characteristic in which luminosity becomes smaller according to distance from the optical axis. The component includes an incidence portion at a source position struck by light from the source and guiding portions branching from the incidence portion and extending radially from the source position. Each guiding portion includes a basal end portion joined to the incidence portion, emission end portion emitting light away from the source, and reflection surface guiding light that struck the basal end portion while performing internal reflection. The incidence portion and guiding portions form a light distribution structure arranged so that a ratio of luminosity in a direction making a predetermined angle with the optical axis with respect to luminosity in the axial direction in light emitted from the structure is larger than a corresponding ratio in the source's distribution characteristic.

Abstract: A plurality of signal display lamps 1A to 1E are communicably connected together through a network 3. Each of the signal display lamps 1A to 1E includes a display portion 12 capable of performing a variable display. Each of the signal display lamps 1A to 1E is capable of performing a mirroring operation in addition to being capable of performing a variable display in the display portion 12 in response to an input signal that is input from input signal lines 8A to 8E. For example, in the signal display lamp 1A, any of the signal display lamps 1B to 1E is selected, and its display state can be simulated. Each of the mirroring source signal display lamps 1B to 1E can be selected by giving a selective command signal from a selective-command-signal generating device 60 connected to the input signal line 8 of the signal display lamp 1A.
