Title:
BIDIRECTIONAL COLORED LAMP HAVING SERIAL-PARALLEL POWER LINE PULSE SIGNAL-TRIGGERED OPERATIONS
Document Type and Number:
WIPO Patent Application WO/2023/231658
Kind Code:
A1
Abstract:
Disclosed in the present invention is a bidirectional colored lamp having serial-parallel power line pulse signal-triggered operations, comprising: a power line pulse-triggered bidirectional light-emitting lamp string, a first controllable switch, a second controllable switch, a third controllable switch and a fourth controllable switch. The power line pulse-triggered bidirectional light-emitting lamp string comprises a plurality of bidirectional light sources. Each bidirectional light source comprises a power line pulse signal-triggered light-emitting module and a reverse light-emitting module. The power line pulse signal-triggered light-emitting module comprises an LED colored lamp set and an LED driver used for driving the LED colored lamp set according to a power line pulse signal loaded on the power line. According to the present invention, by controlling the second controllable switch and the fourth controllable switch, the bidirectional colored lamp driven by power line pulse signal triggering is realized, and a control circuit is simplified; moreover, one optical spectral range is obtained on the basis of a forward current and by means of a power line pulse signal-triggered operation, and another optical spectral range is added by reversing the direction, and thus mere two power lines can greatly increase the optical spectral ranges of the light sources, the lamp string, and the control device thereof.
