Abstract
The invention is directed to a linear luminous body comprising: a light source; a light source accommodating portion in which the light source is accommodated; and a light guide held by the light source accommodating portion so as to extend from the light source accommodating portion; wherein a light emitted from the light source is introduced into said light guide through an end surface of said light guide.
Claims11
A linear luminous body comprising:
- a light source;
- a light source accommodating portion in which the light source is accommodated;
- a light guide held by the light source accommodating portion so as to extend from the light source accommodating portion;
- a linear core made of a member selected from the group consisting of a metal, an alloy and a synthetic fiber;
- and
- a light-reflective layer on a side circumferential surface of said linear core,
- wherein a light emitted from the light source is introduced into said light guide through an end surface of said light guide, and
- wherein said side circumferential surface of said linear core is covered with the light guide.
