Abstract
A table lamp includes an infrared light sensor, a distance detection unit, a light source, and a control unit. The infrared light sensor detects infrared light. The distance detection unit detects a distance between an external object and the distance detection unit. The light source emits light. The control unit controls the light source at least according to intensity of the infrared light detected by the infrared light sensor and the distance detected by the distance detection unit.
Claims19
A table lamp comprising:
- an infrared light sensor configured to detect infrared light;
- a first distance detection unit configured to detect a first distance between an external object and the first distance detection unit when the infrared light is beyond a predetermined intensity range;
- a light source configured to emit light;
- and
- a control unit configured to control the light source at least according to intensity of the infrared light detected by the infrared light sensor and the first distance;
- wherein the control unit turns on the light source when the intensity of the infrared light is beyond the predetermined intensity range and the first distance is smaller than a predetermined value.
A table lamp comprising:
- a first distance detection unit configured to detect a first distance between an external object and the first distance detection unit;
- a second distance detection unit configured to detect a second distance between the external object and the second distance detection unit;
- a light source configured to emit light;
- and
- a control unit configured to issue a warning signal according to comparison results of comparing the first distance with a first standard value and comparing the second distance with a second standard value;
- wherein the first distance detection unit and the second distance detection unit are disposed on the table lamp at a same height, and a distance between the first distance detection unit and the second distance detection unit is equal to a regular width of a human head.
A method for operating a table lamp, the table lamp comprising a first distance detection unit, a second distance detection unit, and a light source, and the method comprising:
- the first distance detection unit detecting a first distance between an external object and the first distance detection unit;
- the second distance detection unit detecting a second distance between the external object and the second distance detection unit;
- and
- issuing a warning signal according to comparison results of comparing the first distance with a first standard value and comparing the second distance with a second standard value;
- wherein the first distance detection unit and the second distance detection unit are disposed on the table lamp at a same height, and a distance between the first distance detection unit and the second distance detection unit is equal to a regular width of a human head or shoulder.
