Abstract

The invention relates to the field of lighting equipment, in particular to a current-conducting plate. The current-conducting plate comprises a base plate and two or three conductive strips, the baseplate is a magnetic material component, the conductive strips extend in the length direction of the base plate, a gap is formed between every two adjacent conductive strips, a first insulating layer is bonded to one side of the base plate, the conductive strips are bonded to one side, back to the base plate, of the first insulating layer, and the thickness of the first insulating layer is 0.15-0.3mm. By adopting the current-conducting plate provided by the invention, the problem of short circuit in use due to insulation failure caused by displacement of the first insulating layer is eliminated. The current-conducting plate with electricity taken from the bottom is used for supplying power to a light source, and the distance between the light source and the base plate is only the thicknessof the first insulating layer, namely 0.15-0.3 mm, and is far smaller than the distance between a light source and a base plate in the prior art, so that the magnetic force between the light source and the base plate is enhanced, and the adsorption effect of the base plate on the light source is enhanced.

Description

technical field [0001] The invention relates to the technical field of lighting equipment, in particular to a conductive plate for taking power from the bottom, a track lamp and a production method for the conductive plate. Background technique [0002] At present, the electromagnetic suction track at the bottom usually adopts the combination of iron plate and PCB circuit board. The PCB circuit board transmits power to the light source. There is an iron plate under the PCB circuit board. An insulating highland barley paper is arranged between the PCB board and the iron plate. A magnet is arranged on the light source to prevent the light source from detaching from the track. [0003] Currently used PCB circuit boards can be divided into single-sided conductive PCB boards and double-sided conductive PCB circuit boards. When using a single-sided conductive PCB circuit board as a conductive carrier, the rails need to be connected with rail connectors to ensure electrical commun...
