Substantially contact point form.According to the present invention, the contact point corresponding with the second to the 4th light emitting module 122,123,124 difference
The specific location being arranged on pivot 125.For example, in the light fixture of the present invention, as shown in the figure, it is contemplated that the second light emitting module
122 deviate 90 degree under its fully unfolded position relative to the first light emitting module 121, thus can will be with the phase of the second light emitting module 122
Corresponding contact point is arranged on 90 degree of opening positions (wherein, second hair of 0 degree of position correspondence shown in Figure 12 on pivot 125
The position that optical module 122 is in fully retracted position).Similarly, can be by the contact point corresponding with the 3rd light emitting module 123
The 180 degree opening position being arranged on pivot 125, and the contact point corresponding with the 4th light emitting module 124 can be arranged on pivot
270 degree of opening positions on 125.So as to when each second to the 4th light emitting module 122,123,124 rotates respective predetermined angle
It can switch on power after degree and light, i.e. each electrical contacts actually play the on-off action to corresponding light emitting module.
Although example from above illustrates that electrical contacts can be placed in contact a form, electrical contacts are not limited to this.
For example, it can also be placed in contact strips, so that when light emitting module rotates predetermined angle relative to fully retracted position
After degree can with corresponding bow strip formed make electrical contact with, and thereby realize with being electrically connected for power supply and light；And can be with
So that light emitting module is further continued for after the predetermined angular is rotated, rotation certain limit can also be kept and bow strip is electric
Contact, i.e. so that light emitting module can keep luminance in certain slewing area.The electricity of such contact strips
Contact site can be more user-friendly, and can avoid point-like contacts portion easily caused loose contact the problem of.
In summary, the predetermined angular for electrical contacts is less than or equal to the maximum pivot for corresponding light emitting module
Gyration, or, in other words, preferably the predetermined angular for electrical contacts is set smaller than or equal to for corresponding
Light emitting module maximum pivoting angle.Point-like contacts portion causes maximum pivoting angle when corresponding light emitting module only turns to
When just can be achieved be electrically connected, and strip-shaped contact portion cause corresponding light emitting module can corresponding light emitting module rotate be less than maximum pivot
It can be achieved to be electrically connected and can be always maintained at during being further continued for turning to maximum pivoting angle after the angle of gyration
Connect.
