PROBLEM TO BE SOLVED: To provide a luminaire that uses an LED as a light source, obtains a luminous intensity required even with one LED, has a structure with a circular shape that has the highest luminous intensity in a center thereof and spreads the luminous intensity around the center like a conventional irradiation pattern, and is easy to be carried.SOLUTION: A luminaire, using an LED 1, can perform flickering by directly turning a light source on/off to send a signal; and using a light guide body 2 with a circular cross section in which light of the LED is incident and is radiated at another end surface, makes the size of the incident end surface of the light guide body into the minimum size enough to put all light emitting elements of the LED therein, and has a structure that collects light between the LED and the incident end surface without leaking light to its surroundings. A secondary battery 16 to be the power source, using the LED, is installed in a lighting body and can be charged without removing it from the lighting body. |
