Claim:
1. A suction anchoring device adapted to use in a light fixture for anchoring the light fixture on a contact surface, the light fixture including a main body, said suction anchoring device comprising: a base unit that includes a movable unit that includes wherein, when the light fixture is being placed on the contact surface, said movable unit is moved relative to said base unit, by weight of the main body of the light fixture, from a lifted position, where said seal member is free from contacting said bottom wall of said casing, to an anchored position, where said press surface of said seal member sealingly covers said vent opening so as to form a suction-forming space which is cooperatively defined by said base unit and the contact surface, and in which a part of air is vented out to provide a suction force that permits said surface-contacting member to be stably attached onto the contact surface; wherein, when the light fixture is being lifted from the contact surface, said movable unit is moved relative to said base unit from the anchored position to the lifted portion, such that said press surface of said seal member is spaced apart from said vent opening to establish spatial communication between said suction-forming space and said internal space and to dismiss the suction force.
