The working process and principle of the present embodiment are as follows:

1. Hemispherical LED lamp lighting: when the indoor light is dark, turn on the auxiliary light to adjust the indoor illuminance; when the indoor illuminance is insufficient, turn on the main light, and the dot-shaped LED lights arranged along the radius of the sphere have a large irradiation space to increase the indoor illuminance. average;

2. Plum blossom-shaped LED lamp lighting: When most family members need to watch TV, have a small talk or have a quiet rest, it is necessary to reduce the indoor illumination, while a few people need to read books or read newspapers, and when the indoor illumination needs to be increased, the output shaft of the micro-motor is decelerated. Drive the eccentric sheave to start to rotate in the forward direction, as shown in Figure 3, the arc groove of the eccentric sheave pushes the ejector rod through the roller to start sliding downward, the ejector rod pushes the slider assembly to start sliding along the hollow slide rod, and the slider assembly pushes Several connecting rods make planar movement synchronously, and several swing rods swing positively synchronously relative to the fixed support, so that several roller groups roll synchronously outward along the corresponding several Feng-shaped pressure plate chute, and the connecting rods push several Feng-shaped The pressing plate rotates synchronously and positively relative to the single earring of the base. Several Feng-shaped pressing plates respectively push several spherical petals to overcome the tension of the tension spring and expand outward synchronously. When the component slides down the hollow slide bar to the position shown in Figure 7, the output shaft of the decelerated micro-motor stops forward rotation, and the tension of the tension spring and the pressure of the Feng-shaped pressure plate act on the spherical petals at the same time, so that the spherical petals are deformed into approximately flat petals , into a plum-shaped lamp lighting, which increases the illumination of the space near the lamp, and reduces the illumination of other indoor spaces, meeting the individual needs of family members.

3. Restore the hemispherical LED lamp: the eccentric sheave of the output shaft of the deceleration micro motor starts to rotate in reverse, the arc groove of the eccentric sheave pulls the ejector rod through the roller and starts to slide upward, and the ejector rod pulls the slider assembly to start sliding upward along the hollow slide rod , the slider assembly pulls several connecting rods to move synchronously in the plane, and several swing rods swing in reverse synchronously with respect to the fixed support, so that several roller groups roll inward synchronously along the corresponding several Feng-shaped pressure plate chutes, and the connecting rods Pull several Feng-shaped pressure plates to rotate synchronously and reversely relative to the single earring of the base, and several Feng-shaped pressure plates are gradually disengaged from contact with several petals synchronously, and the tension of the tension spring makes the petals gradually retracted inward. It is beneficial to retract the petals, and the rubber elasticity makes the petals gradually recover from the approximate plane shape to the spherical shape. When the push rod pulls the slider assembly and slides up the hollow slide rod to the position shown in Figure 3, the output shaft of the deceleration micro motor stops reverse Turn it into a hemispherical LED lamp.
