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

Lens component, indicator unit for signal indicating light, and signal indicating light

A display lamp in which the front face of a non-display portion ( ) is surrounded by a globe ( A) serving as a display portion and in which a light source ( ) is disposed inside of the space defined by the globe ( A) and the non-display portion ( ). The light source ( ) comprises at least a pair of left and right LEDs ( ) disposed at both sides which sandwich the transverse center of the front face of the non-display portion ( ). The LEDs ( ) respectively irradiate lights to those zones of the globe ( A) which are located in the opposite sides with respect to the LEDs ( ) on the basis of the transverse center of the globe ( A). Preferably, the pair of LEDs ( ) comprises a pair of left- and right-side end LEDs ( ) disposed at the left- and right-side ends or their vicinities of the front face of the non-display portion ( ).

Display lamp

A light emitting diode indicator lamp comprising a single globe or a plurality of globes arranged one on the other and LEDs installed in the globe(s) as the light source so that the LEDs are disposed at the prescribed intervals on or near the inner circumferential surface of the globe(s) and diffusing light from the LEDs travels diametrically in the globes(s) and is illuminated to the outside of the globe(s).
