The working process and principle of the present embodiment are as follows:
1. hemispherical LED lamp illumination: when indoor light is darker, auxiliary lamp illumination adjustment indoor illumination intensity is turned on, when indoor photograph
When degree is insufficient, king light illumination is opened, the dotted LED light irradiation space laid along spherical radius direction is big, and indoor illumination intensity is made to be averaged；
2. quincunx LED lamp illumination: when kinsfolk majority need to see TV, small chat or when quiet rest, need
Reduce indoor illumination intensity, and a few peoples need to read or read newspaper, when needing to increase indoor illumination intensity, the driving of deceleration Miniature electric machine output shaft
Screw rod starts to rotate forward, position as shown in Figure 3, and screw rod pushes sliding block to start slide downward, slipper push number along hollow slide bar
A connecting rod, which synchronizes, makees plane motion, and several swing rods are swung relative to fixed support synchronous forward, makes several roller groups respectively along right
The several rich outside synchronous rollings of font pressing plate sliding slot answered, connecting rod push several rich font pressing plates to synchronize just with respect to matrix monaural ring
To rotation, several rich font pressing plates push several spherical surface petals that tension spring tension is overcome to synchronize outside expansion respectively, open up on matrix
Polygon of circular arch slot be conducive to that petal is unfolded, when screw rod push sliding block be snapped down to position as shown in Figure 7 along hollow slide bar when,
The stopping of deceleration Miniature electric machine output shaft rotates forward, and acts on spherical surface petal simultaneously in the pressure of tension spring tension and rich font pressing plate
On, so that spherical surface petal is deformed into almost plane petal, become quincunx lamp lighting, space near under lamp is made to increase illumination,
Other interior spaces reduce illumination, meet the individual demand of kinsfolk.
3. restoring hemispherical LED lamp: deceleration Miniature electric machine output shaft driving screw rod starts to rotate backward, and screw rod pulls
Sliding block starts upward sliding along hollow slide bar, and the several connecting rods of sliding block pulling, which synchronize, makees plane motion, and several swing rods are relative to fixation
It supports synchronous backward to swing, several roller groups is made to synchronize inward roll, connecting rod along corresponding several rich font pressing plate sliding slots respectively
Pull several rich font pressing plates to rotate relative to matrix monaural ring synchronous backward, several rich font pressing plates it is synchronous gradually with several petals
Contact is disengaged, tension spring tension packs up petal inwardly gradually, and the polygon of circular arch slot opened up on matrix is conducive to pack up petal,
Caoutchouc elasticity makes petal be gradually brought to spherical shape by near-planar shape, when screw rod pulls sliding block to slide to along hollow slide bar
When position as shown in Figure 3, the stopping of deceleration Miniature electric machine output shaft is rotated backward, and becomes hemispherical LED lamp.
