Abstract: A spotlight assembly (10) mounted on the roof (R) of an automotive vehicle is manually actuated from a handle (28) to direct a light beam from a lamp unit or assembly (16) in a desired direction. Lamp unit (16) has a generally air tight space formed between a transparent lens (62) and a reflector (40). An inlet opening (63) is provided in a gap in a gasket (58) between the reflector (40) and lens (62) to permit air to enter the interior space. A discharge opening (65) is provided in the bottom of each bowl portion (46) of the reflector (40) to permit the discharge of air from the inner space of the lamp unit (16). A baffle attachment (64) is provided beneath each discharge opening (65) when the lamp unit (16) is in a retracted position as shown in FIG. 5. Baffle attachment (64) has a pair of vanes or baffles (70) which converge in a rearward direction toward the discharge opening (65) to create a venturi effect.

Abstract: A hand operated spotlight assembly (10) for mounting on a roof (R) of an automotive vehicle including inner and outer hemispherical mounting members (20, 21) fixed on opposed sides of the roof (R). Inner and outer movable frames (12, 14) are mounted on the fixed mounting members (20, 21) in a ball and socket connection for relative rotative and tilting movements upon actuation of a handle (50). An actuating member (66) is mounted for pivotal movement about a fixed pivot (68) on the handle (50) and upon movement of a lever (56) and a cooperating link (60) draws inner and outer movable members (12, 14) into tight frictional engagement with fixed mounting members (20, 21). The handle (50) is formed of a pair of handle halves (48A, 48B) which are secured to each other about a control mechanism (56, 60, 66, 84).

Abstract: A spotlight assembly (10) has inner and outer hemispherically shaped mounting members (20, 21) fixed to the roof (R) of a vehicle (A). Inner and outer movable frames (12, 14) are mounted on the fixed mounting members (20, 21) for relative rotative and tilting movements upon actuation of a handle (78). A lamp unit (16) is mounted on outer movable frame (14) about horizontal pivots (90, 91) from linkages (106, 50, 51). The tilting movement of handle (78) results in a tilting movement of lamp unit (16) around three times the angular movement of handle (78) to permit lamp unit (16) to be easily folded to a protected retracted position as shown in FIG. 3.
