Abstract
A lamp comprises a light source (1), a battery (2) and a switch unit (3) which are electrically interconnected. The lamp's reliability, wear life and corrosion resistance are increased by the switch unit being a magnetic switch (3), which by an electrically insulating moulding material is moulded in the same unit as the light source (1) and the battery (2), and which is operated externally by a movable magnet (4).
Claims13
A lamp device comprising a lamp device housing (5), a light source (1), battery means (2), and a magnetically operated switch unit (3) connected between the light source and the battery, said switch unit (3) being operable through use of magnetic means (4) movable relative to the exterior of the housing (5),
- wherein all electrical connections between said light source (1), said battery means (2) and said switch unit (3) are welded or soldered thereto, respectively, and
- wherein said battery means (2), said switch unit (3), said electrical connections, as well as non-radiating parts of the light source (1) are embedded in a cavity-free way in said housing, said housing being formed by an electrically insulating, unitary moulding material (5) to create a corrosion-free environment within the housing.
