Light-emitting modules and lighting modules

摘要

A light-emitting module includes: (a) a liquid-crystal module containing a pair of transparent substrates and a liquid-crystal layer disposed between the pair of transparent substrates; (b) a first light-emitting diode (LED) component disposed on a first side of the liquid-crystal module; (c) a first transparent cover plate over the first LED component such that the first LED component is sandwiched between the liquid-crystal module and the first transparent cover plate; and (d) a control circuit configured to control an on/off frequency of the liquid-crystal module and a light-emitting frequency of the first LED component in such a manner that the light emitted from the first LED component is synchronously shielded by the liquid-crystal module, wherein the light is emitted from a side opposite to the liquid-crystal module.

1. A light-emitting module, comprising:
a liquid-crystal module comprising:
a pair of transparent substrates; anda liquid-crystal layer disposed between the pair of transparent substrates; a light-emitting diode (LED) component disposed on a first side of the liquid-crystal module; a transparent cover plate over the LED component such that the LED component is sandwiched between the liquid-crystal module and the transparent cover plate; and a control circuit configured to control an on/off frequency of the liquid-crystal module and a light-emitting frequency of the LED component in such a manner that light emitted from the LED component is synchronously shielded by the liquid-crystal module, wherein ambient light is able to transmit through the light-emitting module when the liquid-crystal module is in an on-state.
