[0002] Currently, popular toys on the market include magic wands. When children perform on stage with magic wands, other control devices are needed to control the magic wands in the children's hands to light up at a specific time. However, the current wireless remote signal control involves radio frequency / high frequency technology, which involves more external circuits. There are many toys like smart lighting control boxes on the market, but they are mainly composed of more external circuits or hardware circuits, which will have problems such as large size, poor stability and high price.
[0003] Therefore, in response to the above problems, a lighting control box is needed. Utility Model Content

It is radiated into space through the antenna, and is received by the wireless receiving unit, and the display light is turned on or off.
[0010] After pressing the touch switch, the signal is output to the signal light through the control switch, and the signal sending status is displayed through the indicator light.

Then, by pressing the horizontal bar on the control box to trigger the touch switch, the wireless transceiver unit modulates the electrical information source through high-frequency current inside, modulates a 433.92MHZ frequency, forms a radio frequency signal, and transmits it into the air through the antenna. The wireless receiving unit at the receiving end receives the radio frequency signal and then de-modulates it to restore it to the electrical information source. This series of steps realizes short-distance wireless signal control. BRIEF DESCRIPTION OF THE DRAWINGS
