A vehicular lamp can include a guiding lens having a polygonal outline. The guiding lens can include divided portions around the optical axis with an equal center angle. The divided portions can each have an incidence face, a reflection face that can reflect to an optical axis direction light emitted from a light source and having passed through the incidence face, and a light-exiting face that can allow the light from the reflection face to pass therethrough to be projected in an illumination direction of the vehicular lamp. Each divided portion can have an outer-diameter end of the light-exiting face or reflection face at a position farthest from the optical axis within a plane including the maximum radius portion of the divided portion and the optical axis.

A lighting device can include an LED and a plate-like lens body including a narrow side surface configured as an elongated rectangular light exiting surface. The LED can face towards the lens body so that light emitted in a wide angle direction is directed to the front surface and the rear surface in the thickness direction and so that light in a narrow angle direction can impinge on the second side surface of the lens body to enter the lens body. The lens body can include a first optical system having a lens portion, a first light incident surface, a first total reflection surface, and a second total reflection surface. A second optical system can include a second light incident surface, a third total reflection surface, and a fourth total reflection surface. An air layer can be provided between the lens portion and the first light incident surface.

A vehicle lighting assembly is provided which uses a light guiding lens without a dedicated light source. The vehicle lighting assembly can include: a light source configured to emit light rays used at least for forming a target light distribution; a light guiding member made of a transparent or semi-transparent material, the light guiding member including a plurality of individual reflective light emitting surfaces configured to be illuminated with light rays entering the light guiding member from the light source, the light guiding member including another reflective light emitting surface configured to be illuminated with parallel light rays entering the light guiding member; and a reflector having a first reflective surface configured to reflect light rays emitted from the light source for use in forming the target light distribution and a second reflective surface configured to adjust a leak portion of light rays that are not for use in forming the target light distribution so that the leak portion of light rays are made parallel with each other.

The present invention provides a method for stabilizing fine particles of calcium phosphates without lowering their solid phase forming activity.It is possible to stabilize the fine particles of calcium phosphates by stopping the growth of the fine particles formed in an aqueous solution supersaturated with respect to calcium phosphates. More specifically, the fine particles of calcium phosphates were stabilized by lowering the inorganic ion concentration of a fine-particle-forming solution containing fine particles of calcium phosphates by dialysis, ion exchange, dilution, or the like, or by separating the fine particles of calcium phosphates from the fine-particle-forming solution by filtration, centrifuging, or the like.

A vehicle light can project light beams through ring-shaped or arc-shaped light exiting surfaces, and among them the outermost and innermost light exiting surfaces are brighter than the others. The vehicle light can include a light emitting element having an optical axis and a light guide lens having an incidence surface on which light beams from the light emitting element at a certain angle (θ4 to θ5) impinge, reflection surfaces reflecting the light beams so that the light beams are parallel to each other, and light exiting surfaces configured to allow the reflected light beams to pass therethrough. In this vehicle light, light beams emitted at a certain angle (θ4 to θ4a where θ4

Disclosed is a vehicle light fitting unit that can include a plurality of light sources, a reflecting plane which diffusely reflects light emitted from the plurality of light sources, and a lens which emits the light, which is diffusely reflected by the reflecting plane, to a front direction. The plurality of light sources can each be provided so that a pitch between one light source and another light source adjacent to the one light source is shorter than a light path length from the one light source to the lens passing through the reflecting plane.

A vehicle light can include a reflector and a light source. The reflector has a reflection surface formed by at least part of a parabolic cylindrical surface obtained by moving a parabola by parallel displacement, where the parabola has a coefficient of 0.5, a focal length, and a focal point. The light source includes at least one set of at least two light emitting devices that have respective light emission surfaces facing toward the reflection surface. The at least two light emitting devices include a front light emitting device and a rear light emitting device spaced apart by a predetermined distance along an illumination direction of the vehicle light, with the focal point interposed between the front and rear light emitting devices.
