Abstract: A vehicle lamp includes a semiconductor laser element configured to emit laser light; a condenser lens configured to condense the laser light, a phosphor configured to form white light by converting wavelength of at least a portion of the laser light condensed, and a reflector configured to reflect the white light. A scattered light forming part is formed on a surface of the reflector, which is a surface at which a path obtained by extending an optical path of the laser light before the laser light hits the phosphor is intersected with the reflector.

Abstract: A vehicle lamp includes a planar light-emitting structure having a substrate on which an organic EL emission element is provided, a framing member that fixes the planar light-emitting structure inside a vehicle-lamp light cabinet, and an elastic member that is interposed between the planar light-emitting structure and the framing member and that fixes the planar light-emitting structure by its biasing force.

Abstract: A planar light emitting body 6 configured to emit a first illumination light, and a semiconductor light emitting element 7 configured to emit light toward the planar light emitting body 6 are disposed in a lamp chamber 5 defined by a lamp housing 2 having an opening and a cover 3 that covers the opening. The planar light emitting body 6 includes a transmitting layer through which light is caused to pass, and a control layer configured to irradiate light as a second illumination light by controlling a travelling direction of the light that is emitted from the semiconductor light emitting element 7 and passes through the transmitting layer.

Abstract: A vehicle lamp includes a lamp housing having an opening and a cover attached to the lamp housing and closing the opening to form a lamp chamber, and a lamp unit disposed in an interior of the lamp chamber and including a light source having a plurality of planar light emitting bodies. An outer peripheral portion of each of the planar light emitting bodies is a non-light emitting region, and a portion inside the non-light emitting region of each of the planar light emitting bodies is a light emitting region. At least a portion of the non-light emitting region is formed to be transparent. The transparent portion of the non-light emitting region of the planar light emitting bodies and an outer end portion of the light emitting region of other planar light emitting bodies are superimposed to each other in a thickness direction of the planar light emitting bodies.

Abstract: A light emission device includes an organic EL panel and a molding resin. In the organic EL panel, an organic EL light emission portion is formed on a substrate. The organic EL panel is flexible. The molding resin shapes the organic EL panel so that the organic EL panel is in a curved state.

Abstract: A vehicular lamp includes a planar light emitting member having an organic EL light emitting portion at part of a substrate, and a reflecting member and a half mirror that are disposed so as to face each other so that light emitted from the organic EL light emitting portion is reflected repeatedly while allowing part of the light to be transmitted to the front.

Abstract: An electric discharge lamp has a ceramic luminous tube 5 and filled with xenon gas, a pair of electrodes 9, 10 held by the ceramic luminous tube, and a glass outer tube 6 accommodating the ceramic luminous tube and the pair of electrodes. The ceramic luminous tube includes a luminous portion 7 emitting light by electric discharge, and a pair of small diameter tube portions 8, 8 respectively connected to both end portions of the luminous portion in a longitudinal direction. Value of P/(r•t) is not less than 4.8 and not more than 32, where P (atm) is pressure of xenon gas filled into the ceramic luminous tube, r (mm) is an inner diameter of the luminous portion of the ceramic luminous tube, and t (mm) is thickness of the luminous portion of the ceramic luminous tube.

Abstract: There is provided a mercury-free discharge bulb for a vehicle. The mercury-free discharge bulb includes an arc tube. The arc tube includes: a light-emitting portion which is formed of a ceramic tube and includes a light-emitting material and a starting xenon gas filled therein, wherein a filling pressure of the starting xenon gas from about 6 atm to about 18 atm; thin tube portions which are formed at respective ends of the light-emitting portion; and electrodes which are fixed inside the thin tube portions and which are provided in the light-emitting portion so as to face each other. The light-emitting material includes at least a sodium halide and a rare-earth metal halide excluding a scandium halide, and a difference between a vapor pressure of the sodium halide and a vapor pressure of the rare-earth metal halide under an environment of about 1000° C. is about 10 kPa or less.

Abstract: A sealed lead acid storage battery includes a monoblock container, a cover, plural assembly elements, each assembly element comprising a plurality of positive and negative electrode plates that are stacked via separators in a predetermined direction, a positive and negative electrode strap, and a positive and negative electrode terminal. The positive and negative electrode terminals protrude above the cover. The container further comprises ribs formed inside a bottom surface thereof for enabling the electrode plates to rest on the ribs. Each positive electrode plate has a pair of feet that are formed on a lower end thereof in a substantially symmetrical arrangement and further comprises a lug connected to the positive electrode strap that is disposed at a position shifting either to the left or to the right. One of the feet correspond to the position having the lug not resting on any rib, while the other foot rests on a rib.
