| Zusammenfassung: | A lighting device includes a power switcher, a first light emitting diode string light and a second light emitting diode string light circuit. The power switcher is respectively electrically connected with the first light emitting diode string light and the second light emitting diode string light circuit. The second light emitting diode string light circuit includes a charge-discharge unit and a second light emitting diode string light being different from the first light emitting diode string light. The lighting device has a first lighting state and a second lighting state, wherein the power switcher supplies power to the first light emitting diode string light in the first lighting state, and the charge-discharge unit supplies power to the second light emitting diode string light in the second lighting state. The lighting device has the light-off delay effect for turning from the first lighting state to the second lighting state to assist lighting spatial profile. |
