Synchronous control device and method for led lights

Abstract

Embodiments of the present invention provide an LED lamp synchronous control device and method. The LED lamp synchronous control device includes: a white light emitting circuit, a synchronous control module and a colored light emitting circuit; the white light emitting circuit includes a white light emitting module and a white light driving module; the colored light emitting circuit includes a colored light emitting module, a controllable switch and a colored light driver module. The white light emitting circuit is electrically connected to the synchronous control module, and the output end of the synchronous control module is electrically connected to the control end of the controllable switch. The white light emitting circuit generates a driving signal for driving the white light emitting module to emit light; the synchronous control module receives the driving signal and processes it so as to output a low-level signal when the white light driving module controls the white light emitting module to be turned off, which is controllable The switch is turned off, so that the color light emitting module in the color light emitting circuit is not turned on; when the white light driving module controls the white light emitting module to be turned on, a high level signal is output, and the controllable switch is turned on, so that the color light emitting circuit in the color light emitting circuit The colored light emitting module is turned on.

Description

technical field [0001] The embodiments of the present invention relate to the field of lamp control, in particular to a device and method for synchronously controlling LED lamps. Background technique [0002] With the gradual expansion of LED (Light Emitting Diode, light-emitting diode) general lighting and landscape application markets, consumers' requirements for LED lights for lighting and landscape are also increasing. [0003] In traditional LED lanterns, the internal colored light emitting circuit and white light emitting circuit are independent, and the control circuit of the colored light emitting circuit and the control circuit of the white light emitting circuit also work separately. [0004] When synchronous control of colored light and white light is required, such as synchronous start and synchronous change of control, if the start-up time of the two power sources is inconsistent, the situation that the LED lights cannot be controlled synchronously will affect t...
