Abstract: A turn signal for a vehicle has a blue LED as a light source, and an outer cover irradiated by the blue light. The outer cover includes a molded body of a polymeric material including phosphors dispersed therein that absorb blue light and emit light. By means of the present invention, it is possible to provide a turn signal for vehicles which has improved visibility and which imparts excellent visibility and sufficient luminous intensity over a wide angle. Further, because the entire outer cover surface-emits light, uniformity of luminous intensity is ensured without subjecting the outer cover to light scattering treatment, enabling as a result preventing glare caused by light scattering treatment, making this turn signal safe without being unpleasant for pedestrians and drivers of nearby vehicles. Furthermore, because no complex optical design is necessary, this turn signal saves space and can be arranged in a vehicle.

Abstract: In the present invention, a crucible formed of SiC as a main component is used as a container for a Si—C solution. The SiC crucible is heated such that, for example, an isothermal line representing a temperature distribution within the crucible draws an inverted convex shape; and Si and C, which are derived from a main component SiC of the crucible, are eluted from a high-temperature surface region of the crucible in contact with the Si—C solution, into the Si—C solution, thereby suppressing precipitation of a SiC polycrystal on a surface of the crucible in contact with the Si—C solution. To the Si—C solution of this state, a SiC seed crystal is moved down from the upper portion of the crucible closer to the Si—C solution and brought into contact with the Si—C solution to grow a SiC single crystal on the SiC seed crystal.
