Background

The conventional light cube lamp bead fixing modes are two common: 1, the lamp strip is adopted to be fixed according to a certain distance. 2, one LED driver chip drives one or several lamp pearls, and this kind of drive mode colour is abundant, shows that dynamic effect is good, and driver chip and lamp pearl all are fixed position. And the dynamic effect is realized by adopting a mode of turning on and off the lamp beads or changing different colors. In order to achieve a better dynamic effect, all positions included by the lamp beads are often required. If only a small part of the most core is displayed, the occlusion is obviously seen, and the display effect is greatly reduced. The advantage is that the scheme can display complex graphics, but the display effect of the complex graphics is less than ideal.

The current solution has several disadvantages: 1. the beads have gaps, and when the dynamic effect is like wave shape and other continuously-converted wave shapes, because the gaps between the beads are larger, the waveform conversion is discontinuous and has jumping, especially when the wave conversion is slower and finer. 2. The stereoscopic effect is relatively poor, and because lamp pearl loading board or parcel (some make the ball bubble lamp, some make the lamp strip and similar energy-saving lamp tube etc. shape), drive chip etc. are opaque, shelter from the great. The stereoscopic effect looks less vivid. 3.

The positions of the wave patterns and the hill patterns are fine and smooth, and the position change is continuous; and lamp area etc. other modes, the change of position is decided by the lamp pearl interval, and the change of carefully seeing the position is jumped.

Because the conducting wire is very thin relative to the bulb, under individual figure, the wire is arranged under the bulb, and the wire can not be seen by naked eyes to shield, thus the display effect is not influenced at all. In the modes of lamp belts and the like, when the number is large, the shielding is serious when the user looks at the side surface; the mode such as lamp ball or fluorescent tube, it has all used dull polish or the mode of samming, when having a plurality of shelters from between spectator and display lamp pearl, its luminance and colour all can take place the change of very big degree, do not reach the effect of expression far away.

3. The utility model discloses a wireless communication mode, host computer carry out lifting control, light regulation control to many controllers through 2.4G wireless signal transmission. The plurality of controllers only need to be flexibly connected in series to arrange power lines.

4. The utility model discloses installation easy maintenance. The bulb is damaged and can be replaced at the highest speed, which is as simple and convenient as the replacement of the traditional white weaving lamp. And the lamp area mode, if the lamp has the dead pixel or damages, because the lamp area is very intensive, the operator is difficult to change. Adopt the design of single-unit module, use the couple fixed, if the driver damages, can change the monomer drive controller that damages. Compared with a lamp belt mode, the wire is few, and the failure rate is also few.

5. The utility model discloses drive control unit's realization scheme is excellent. 1) The stepping motor and the reducer mechanism are adopted, the stepping motor is high in precision and good in linearity, the reducer amplifies the motor torque force and effectively drives the winding roll to act, and the accuracy of ascending and descending of the lamp is greatly guaranteed; 2) the automatic position detection is realized, the state is checked by the limit switch module and the infrared correlation module through the wire winding and unwinding actions, the data operation is driven by the stepping motor, the length of the cable can be obtained, and the follow-up dynamic effect is guaranteed; 3) the cable of control panel to lamp holder in the driver, the cable can follow the reel and rotate, leads to the cable winding, has adopted the slip ring that leads to the electricity to realize 360 rotatory not twines.
