POWER SOURCE LINE PULSE SIGNAL TRIGGERED LIGHT FOR BIDIRECTIONAL LIGHT EMISSION

WIPO Patent Application WO/2023/169427

A1

Disclosed is a power source line pulse signal triggered light for bidirectional light emission, which comprises a first power source line pulse signal triggered light-emitting module and a reverse light-emitting module; the first power source line pulse signal triggered light-emitting module and the reverse light-emitting module are connected in parallel to a first power source line port and a second power source line port of a light source; the first power source line pulse signal triggered light-emitting module comprises an LED colored light group and an LED driver; when an electrical level of the first power source line port is greater than that of the second power source line port, the LED driver drives the LED color light group; otherwise, the reverse light-emitting module operates; and the LED driver comprises: a reverse current blocking module and a power source line pulse signal trigger operation module which are both integrated into a same integrated circuit. The reverse current blocking module is provided in the LED driver and integrated into the same integrated circuit, packaging costs are greatly reduced, packaging efficiency is improved, and the spectral range of a light can be further expanded with just a power source line and a ground line.
