Document Type and Number:
Japanese Patent JP2015022895
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a light-emitting structure in which light emitted from a light source diffuses even further and luminance improves.SOLUTION: A light-emitting structure 11 is configured by: a substantially columnar-shaped body 1 which stores an LED and a power source of it inside; a cylindrical trunk body 5 connected to an upper part of the body 1 and having transparency; a cylindrical body 20 in which a side wall surface 27 made of a translucent material is formed to be a random concavo-convex 29 shape, and which is arranged so that an open one end part 24 located below faces an upper surface of the body 1; and a lid body 6 having translucency and installed detachably so as to block an open end part of the trunk body 5 which is in a position facing the body 1. In this configuration, light emitted from a light source of the LED enters the cylindrical body 20, it is diffused by the concavo-convex 29, and luminance of the light-emitting structure 11 improves.
