Abstract: A light source comprising a prismoidal housing with inclined sides of a flight of steps and with a closed smaller base and an open larger base. The entire inner surface of the housing is made of an optically reflective material. A plurality of light emitting elements are arranged on the smaller base of the prismoidal housing and the respective risers of the steps of each flight such that the plurality of light emitting elements emit rays of light toward the open large base of the housing.

Abstract: A light source apparatus is provided with a prismoidal light source housing having a first inclined surface formed of a dichroic mirror which transmits light of a wavelength less than 600 nm and reflects light of a wavelength of 600 nm or more, a second inclined surface opposed to the first inclined surface and formed of a dichroic mirror which transmits light of a wavelength of 600 nm or more and reflects a light of a wavelength less than 600 nm, green LEDs and blue LEDs are arranged on an external surface of the first inclined surface, and red LEDs which are arranged on an external surface of the second inclined surface.

Abstract: A trim assembly 40 for a vehicle comprising: a top cover 10 comprising gather-sewn peripheral portions 12 and 13 to form gather-sewn portions 15; a plate-like base member 20, to which the peripheral portions 12 and 13 of the top cover 10 are sewn on peripheral portions 22 and 23 of the base member to form sewn portions 26; and a cushion member inserted between the plate-like base member 20 and the top cover 10; wherein a gather-sewn upper peripheral portion 12 of the top cover 10 is overlapped and sewn on an upper peripheral portion on a body side surface of the base member 20 to form a sewn portion 26, the overlapped and sewn top cover 10 is turned over upwardly and further turned over beyond an upper edge of the base member 20 so as to face a room side surface of the base member 20, a gather-sewn lower peripheral portion 13 of the further turned top cover 10 is overlapped and sewn on a lower peripheral portion on the room side surface of the base member 20 to form a sewn portion 26, and the lower peripheral

Abstract: A trim assembly for a vehicle that has gathers approximately paralleling each other. The trim assembly for a vehicle has a top cover, a plate-like base member and a cushion member inserted between the plate-like base member and the top cover. The top cover has a gather-sewing peripheral portion having, when the trim assembly is unfolded, an edge having a stairs-like shape having the first and second oblique portions and an approximately straight portion. The plate-like base member has an edge having, when the trim assembly is unfolded, a stair-like shape having an oblique portion and an approximately straight portion. The trim assembly for a vehicle has a structure that edges of the top cover and plate-like base member are turned back together onto and fastened to the plate-like base member to make a smooth edge line.
