A lens component radiates light from a light source. The lens component includes a light guiding radiation portion. The light guiding radiation portion includes a light incidence portion having an incidence surface on which the light from the light source is made incident, and a plurality of radiation mechanisms that respectively radiate to a plurality of radiation angle ranges. The incidence surface includes a close side incidence region and a distant side incidence region. The radiation angle ranges include a close side radiation angle range and a distant side radiation angle range. The light incident on the close side incidence region is radiated to the distant side radiation angle range via a corresponding distant side radiation mechanism. The light incident on the distant side incidence region is radiated to the close side radiation angle range via a corresponding close side radiation mechanism.

Lens component and signal display lamp

Signal warning and displaying lamp

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.

Lens component and light emitting device

A buzzer unitincludes a case, a vibrating element, and a pressing member. The caseincludes a vibrating platein which no through-holes are formed. The caseincludes a storage spaceformed therein on the lower side Xof the vibrating plate. The vibrating elementfaces the vibrating platein the vertical direction X inside the storage space, produces vibration as a result of voltage being applied thereto, and as a result, causes the vibrating plateto vibrate. The pressing memberis stored in the storage space, and presses the vibrating elementagainst the vibrating plate

A main body caseincludes an output openingfor outputting sound from a sound source to an opposing space between an upper main walland a lower main wall. The main body caseincludes a front main wallfor preventing entering of a water droplet to the output openingand for guiding the sound to a rear side B, and a rear main wallfor reflecting the sound to a front side F. A first spacebetween the front main walland the rear main wall, a second spacesurrounded by a left surfaceC of the front main walland the rear main walland the upper main walland the lower main walland a third spacesurrounded by a right surfaceD the front main walland the rear main walland the upper main walland the lower main wallare communicating with one another along a crosswise direction Y at a rear end part of each of these spaces.

Notification device and signal display light

A signal display lamp is provided that is capable of performing display in diverse modes and hence capable of increasing the quantity of transmittable information and capable of improving the reliability of information transmission. The signal display lamp includes a display portion that is capable of performing display in a plurality of display colors and that is capable of changing a position or a size of a display region in each display color, a display color determining means for determining the display color based on first information, a display region determining means for determining a position or a size of a display region in a display color determined by the display color determining means based on second information, and a display portion control means for controlling the display portion based on a display color determined by the display color determining means and based on a position or a size of a display region determined by the display region determining means.

Signal display lamp

A signal indicator lamp includes an LED mounting substrate, and is made up of a plurality of consecutively provided lens unitswith cylindrical light guiding radiation portionsprovided so as to enclose the LED mounting substrate. An LEDis mounted at a position biased to the side of an end portionD from a central positionC in a short-side direction S of the LED mounting substrate. In the light guiding radiation portion, a slit portionis defined which is cut away in an axial direction X such that the LEDis arranged therein when the lens unitencloses the LED mounting substrate. Light made incident into the lens unitfrom incident surfacesbeing a pair of opposite end faces of the slit portionis guided by the light guiding radiation portion, and is radiated outward in the entire circumferential region thereof.
