Description

Technical Field

[0001] This application relates to the field of lighting equipment, and more specifically, to a transmission mechanism for a rotating light box and a rotating light box. Background Technology

[0002] In the prior art, patent CN102418868A discloses a lighting lamp. Specifically, it includes a reflector, a light source, and a lamp holder. The lamp holder includes an upper lamp holder and a lower lamp holder. The reflector and the light source are fixedly mounted on the upper lamp holder. A lifting device and a rotating device are provided between the upper lamp holder and the lower lamp holder. A connecting member is provided between the rotating device and the upper lamp holder. The upper lamp holder is driven by a fixed frame through a positioning component to rotate the lead wire inside the top ball. Since there is a rotating shaft between the lead wire and the inner cavity of the top ball, a connecting spring block is provided on the outside of the lead wire and it is movably connected to the annular conductive block provided on the side wall of the inner cavity. This movable connection is such that the connecting spring block and the annular conductive block are in close contact and can rotate around the annular conductive block to achieve conductivity during rotation. The connecting ball at the center of the lead wire is movably connected to the conductive block at the center of the inner cavity. The rotating shafts of the lead wire and the top ball are concentric, so that when the upper lamp holder and the lead wire rotate 360 ​​degrees, the top ball and the lower lamp holder remain stationary. The connecting spring block and the connecting ball of the lead wire can be connected to the annular conductive block and the conductive block in the inner cavity of the top ball and conduct electricity to the light source, achieving continuous rotation and oscillation without causing defects such as wire tangling or winding.

[0003] As can be seen from the above, in order to avoid the problem of wire tangling or winding, this patent has designed a very complex structure consisting of a rotating device and a power connection device, so that when the reflector bowl rotates with the upper lamp holder, the power cord inside will not rotate, thereby ensuring normal power supply while avoiding wire tangling or winding.
