Abstract
A random lighting device is disclosed. The random lighting device includes: a plurality of light-emitting units, each including a light emitting diode and a light-emitting control unit for randomly determining a flickering cycle and brightness of the light emitting diode to control the light emission of the light emitting diode; and a control unit for limiting a range of the flickering cycle and brightness of the light-emitting units.
Claims9
A random lighting device, comprising:
- a plurality of light-emitting units, each including a light emitting diode and a light-emitting control unit for randomly determining a flickering cycle and brightness of the light emitting diode to control light emission of the light emitting diode;
- and
- a control unit limiting ranges of the flickering cycle and brightness of the light-emitting units,
