Provided is a display system for a vehicle. The display system includes a display device installed to be visually recognizable from the outside of a vehicle, and a control device configured to cause the display device to display state information of the vehicle. The control device receives a signal from a sensor that senses a distance from the vehicle to an object around the vehicle, and the control device changes display of the display device based on the distance.

Display system for vehicle

The present disclosure provides a vehicular lamp including an organic EL element that has only a non-light emitting point with a size of 120 &#x3bc;m or less on a light emitting surface.

Vehicular lamp, inspection method of organic EL element

A phosphor has the general formula (M,M,M)MOX, wherein Mrepresents at least one element including at least Si and selected from the group consisting of Si, Ge, Ti, Zr, and Sn, Mrepresents at least one element including at least Ca and selected from the group consisting of Ca, Mg, Cd, Co, and Zn, Mrepresents at least one element including at least Sr and selected from the group consisting of Sr, Ra, Ba, and Pb, X represents at least one halogen element, Mrepresents at least one element including at least Euand selected from the group consisting of rare-earth elements and Mn, m is in the range 1&#x2266;m&#x2266;4/3, n is in the range 5&#x2266;n&#x2266;7, and x, y, and z are each in such a range as to satisfy x+y+z=1, 0.45&#x2266;x&#x2266;0.8, 0.05&#x2266;y&#x2266;0.45, and 0.45, and 0.03&#x2266;z&#x2266;0.35.

Phosphor and light-emitting device

A light emitting device is provided with a semiconductor light emitting element and a wavelength conversion portion. The wavelength conversion portion includes an outer peripheral portion between an input surface and an output surface. The outer peripheral portion includes a first inclined part at a side of the input surface and a second inclined part at a side of the output surface. The first inclined part and the second inclined part define a projecting portion that is projected on the outer peripheral portion.

Light emitting device that includes wavelength conversion layer having outer peripheral portion having convex projecting part with light reflection layer formed thereon

A method for preparing a phosphor that comprises a crystalline oxide having MO(Mis a tetravalent metallic element) as a main framework thereof and essentially including a halogen element X (X is at least one element selected from a group consisting of F, Cl, Br, and I) and divalent metal ions Mand Eu, includes using a compound represented by a compositional formula NHX as a starting material when synthesizing the phosphor. At least a compound represented by a compositional formula NHCl may be used as the starting material.

Method for preparing phosphor

A light source module for a vehicle lamp, including an optical system that guides light emitted from the light source module in a certain irradiation direction and has an optical center, the light source module has a plurality of semiconductor light emitting elements disposed in a straight line and electrically connected to each other in series. One of the semiconductor light emitting elements that is positioned closest to the optical center of the optical system has a light emitting area that is smallest of the plurality of the semiconductor light emitting elements.
