ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates down lights and, more particularly, to a recessed down light, does not damage the surface coating of the parts thereof when adjusting the lighting angle of the lamp.
FIG. 1
shows a recessed down light according to the prior art. This structure of recessed down light
1
′ comprises a mounting base frame
11
′, a lamp holder
13
′ pivoted to the mounting base frame
11
′, the lamp holder
13
′ having friction ribs
14
′ at the back side thereof, and a metal friction plate
12
′ fixedly fastened to the mounting base frame
11
′ and pressed on the friction ribs
14
′. The friction resistance between the friction ribs
14
′ and the metal friction plate
12
′ holds the lamp holder
13
′ in one of a series of positions. This design enables the lamp holder
13
′ to be adjusted vertically within 90°. The user cannot adjust the angular position of the lamp holder
13
′ horizontally. Further, when adjusting the position of the lamp holder
13
′, the surface coating of the lamp holder
13
′ may be damaged because it is moved over the metal friction plate
12
′.
SUMMARY OF THE INVENTION
The present invention has been accomplished to provide a recessed down light, which eliminates the aforesaid drawbacks. It is one object of the present invention to provide a recessed down light, which enables the user to adjust the angular position of the lamp horizontally within 355° and vertically within 87° without tangling the electric wires. It is another object of the present invention to provide a recessed down light, which does not cause damage to the surface coating of the lamp holder when adjusting the angular position of the lamp. To achieve these and other objects of the present invention, the recessed down light comprises a mounting base frame, a rotary carrier revolvably supported in the mounting base frame, two friction members fastened to the mounting base frame and pressed on the rotary carrier and adapted hold the rotary carrier in position when external force disappeared, a lamp holder holding a halogen lamp and pivoted to the rotary carrier for turning in and out of the rotary carrier by hand, and a track frame fastened to the rotary carrier and adapted to guide circular motion of the lamp holder in vertical direction within 87°. Further, the lamp holder has a fixed cushion disposed in contact with the track frame, preventing damage to the surface coating of the lamp holder when adjusting the angular position of the lamp holder vertically.
