Abstract: A touch sensitive lighting device and method of controlling thereof. Particularly, the application provides a touch sensitive lighting device which is characterized in having a touch sensitive contact point for operating a lighting source of the touch sensitive lighting device with a single finger of a human being. More particularly, the touch sensitive lighting device comprising of a housing for the touch sensitive lighting device; the lighting source of the touch sensitive lighting device for illumination; a power source for providing power to the lighting source for the touch sensitive lighting device for illumination; the touch sensitive contact point for controlling the lighting source of the touch sensitive lighting device; a circuit board includes circuitry for controlling the lighting source and the power source of the touch sensitive lighting device; and a magnifier lens.

Abstract: A retractable magnifier includes a housing and a lens assembly having a lens carried in a frame. The lens assembly is movable in the housing between a retracted position and an extended position. The housing is provided with push-buttons capable of releasing the lens assembly from the retracted position. A longitudinal rack is formed in the housing. A pinion meshes the rack and has a spindle rotatably connected to the frame. The pinion further includes a helical torsion spring mounted around the spindle and placed in damping oil for urging the pinion in such a direction that the frame may be moved, in a gentle manner, to the extended position. A rocker provided with an electric prefocus lamp is pivotally connected to the housing, and adapted to be pivoted outward at a predetermined angle with the housing when the lens assembly is in the extended position. A switch is formed on the housing for turning on/off the lamp.
