Title:
制御ユニットを備えるＬＥＤフィラメントランプ
Document Type and Number:
Japanese Patent JP7377823
Kind Code:
B2
Abstract:
A light emitting diode, LED, filament lamp (100), comprising a light emitting diode light source (110), comprising at least one first filament (120a), arranged to emit light having a first color temperature, at least one second filament (120b), arranged to emit light having a second color temperature, different from the first color temperature, wherein each of the first and second filaments comprises a substrate (130a, 130b) of elongated shape, wherein at least one light emitting diode (140a, 140b) is arranged on the substrate. The LED filament lamp further comprises a control unit (150) configured to control a first intensity of the light emitted from the first filament(s) and to control a second intensity of the light emitted from the second filament(s) according to at least one predetermined setting, in order to control the total color temperature of the light emitted from the LED filament lamp as a function of the predetermined setting(s).
