Abstract
The utility model provides an LED connection circuit, relates to the field of LED illumination, and especially relates to a connection circuit connecting a plurality of LEDs. The connection circuit comprises a constant voltage circuit, a constant current circuit, an LED series-connection circuit, and a rectification circuit. The constant voltage circuit and the constant current circuit are in parallel connection, and the input end of the LED series-connection circuit is connected with the constant voltage circuit and the constant current circuit. The output end of the LED series-connection circuit is electrically connected with the rectification circuit. According to the utility model, three LEDs serve as an illuminating group, thereby forming the matrix arrangement. Meanwhile, a driving circuit and a power supply are integrated into one body, thereby enabling the management of the whole body to be convenient. Because the driving circuit is built inside, the shape and external structure of a lamp can be changed randomly without being limited by the fact that because a driving circuit module is arranged outside, the appearance of the lamp is affected.
