Claim 14:
15. A lighting device comprising:
a light source unit (110) including one or more light emitting elements;
a first body (180) to which the light source unit is mounted;
a second body (190);
a sensor unit (130), including a magnetic sensor, configured to sense at least one of a relative posture and a relative position of the first body (180) with respect to the second body (190); and
a control unit (120) configured to control a light emitting operation of the light source (110) unit on the basis of at least one of the relative posture and the relative position of the first body (180);
wherein the second body (190) includes a first magnetic material (M1) in a center of the second body,
wherein the first body (180) includes a third magnetic material (M3) disposed in a lower portion of the first body at a predetermined distance from a central axis of the first body; and a fourth magnetic material (M4) disposed in a lower center portion of the first body,
wherein the magnetic sensor is disposed in a lower portion of the first body at a predetermined distance from an upper portion of the third magnetic material (M3),
wherein the first body (180) is fixed to the second body (190) in an upright posture by a magnetic force of the first magnetic material (M1) and the fourth magnetic material, or the first body (180) is fixed to the second body (190) in an inclined posture at a predetermined angle by the magnetic force of the first magnetic material and the third magnetic material, and
wherein the control unit (120) turns on the light source unit (110) if the magnetic sensor is turned on by a magnetic field generated by the first magnetic material (M1).
