PROBLEM TO BE SOLVED: To provide lighting equipment capable of automatically changing an optical signal when the light distribution is changed.SOLUTION: A lighting equipment 1 includes: a fixed part 31; a lamp body 32 holding a light source; a first coupling part 33 and a second coupling part 34 as a light distribution adjusting means which rotatably couples the lamp body 32 to the fixed part 31. Different optical signals are transmitted according to a direction of the lamp body 32 (i.e. according to a direction the transmitted optical signal). When changing the light distribution by changing the direction of the lamp body 32 (light distribution direction), since the optical signal is automatically changed, no work is required to change the position represented by the optical signal. |
