Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to an LED light source board and a lamp. Background Art

[0002] For some smart LED lamps, a control board is generally required to control the light source board to achieve intelligent operation. In order to reduce the connection between terminals and wires, the existing LED light source board adopts an integrated structure. The so-called integrated structure is that the driving circuit, control circuit and LED lamp beads of the LED lamp beads are integrated on the same substrate. However, in order to upgrade and iterate the LED light source board, the driving circuit and the control circuit are generally replaced. Therefore, the existing method directly welds the control circuit and the driving circuit to the same substrate as the LED lamp beads, which is not conducive to the upgrade of the LED light source board. Therefore, how to construct a suitable structure for upgrading the LED light source board is a topic that urgently needs to be studied in the industry. Utility Model Content
