Scalable and regulate the LED Down lamp of direction of illumination
Technical field
The utility model belongs to light fixture lamp body technical field, in particular, belongs to a kind of device of the irradiating angle of lighting being adjusted by multistage arm bearing.
Background technology
In prior art, the irradiating angle of Down lamp is difficult to regulate conventionally, Fig. 1 is a kind of lamp body structure form of Down lamp in prior art, connecting rod 14 links together by a bolt 6 with the U-shaped support 13 of middle fluting, connecting rod 14 is hinged with lamp body module 2, lamp body module 2 just can move up and down by connecting rod 14 in the fluting of U-shaped support 13, can stretch out and indentation cover 1.Lamp body module 2 can be by swinging with regulating irradiation angle in the hinged place perpendicular of connecting rod 14.U-shaped support 13 can be around the axis rotation of the junction of itself and fixed head and support 5, and the below of another fixed head 5 is provided with caging bolt 7, and this Limit screw 7, for stoping support rotational angle excessive, destroys the wire 8 picking out from lamp body module 2.This lamp body structure complex forms, can only rely on metal and intermetallic frictional force when stretching or waving adjusting angle, and flexible or oscillating motion repeatedly can be worn and torn and easily cause structural failure afterwards, and structural stability is poor.Due to flexible by both sides frictional force control, easily cause discontinuity, stretching can be very not smooth.In the time that lamp body module 2 is stretched out cover 1, wire 8 is outside exposed, affects outward appearance.And wire is along with lamp body module is flexible also and then flexible, easily cause line to fracture or the damaged and electric leakage that causes of crust.
Fig. 2 is another version of Down lamp in prior art, two rivets or screw that lamp body module 2 directly arranges by symmetric coaxial with cover 1 are connected, lamp body module 2 comprises LED light source plate and radiator, LED light source plate is arranged on radiator, LED on LED light source plate can produce heat when illumination, and these heats are conducted to after radiator, be dispersed in air by the fin on radiator by LED light source plate.Adopt this Down lamp lamp body structure form, lamp body module 2 can be with two rivets or screw rotation rotary oscillation, but the pendulum angle of lamp body module 2 relative covers 1 is little, and swing back light module 2 has part light to be blocked, so just can cause the logical waste of light by cover 1.This lamp body structure form stretching motion up and down in addition, range of exposures and the scope of application are little.
