Patent ID: 10890299

Abstract:
The present invention belongs to the technical field of lighting devices, in particular to an LED filament lamp. The LED filament lamp comprises a transparent hood with an opening at the lower end, and a lamp cap connected to the transparent hood, and a light emitting source is arranged in the transparent hood. The LED filament lamp also comprises a support base; the support base is arranged in a space enclosed by the transparent hood and the lamp cap; the light emitting source is fixed on the support base, and the lower end of the light emitting source is connected with the lamp cap through a current limiting resistor. The light emitting source comprises a single strip-shaped substrate, and a plurality of LED wafers; the two ends of the strip-shaped substrate are conductive electrical connecting ends; the plurality of LED wafers are connected in turn and arranged on the strip-shaped substrate at an interval to form a strip-shaped LED wafer set; a rectifying unit electrically connected with the strip-shaped LED wafer set is arranged at each one of the two ends of the strip-shaped LED wafer set; and each one of the rectifying units is fixed on the strip-shaped substrate and is electrically connected with each corresponding one of the electrical connecting ends. The present invention provides an LED filament lamp which is conveniently assembled and can be directly connected with an alternating current.
