Abstract

An embodiment of the invention discloses an LED illumination circuit. The LED illumination circuit comprises a half-wave rectifying circuit, a current control circuit, a first alternating current direct-driven LED chip, a second alternating current direct-driven LED chip, a first resistor and a second resistor. The embodiment of the invention also discloses an illumination lamp. By adoption of the LED illumination circuit and the illumination lamp, the size of the illumination circuit is reduced; the cost is relatively low; and the service life is prolonged.

Description

Technical field [0001] The invention relates to the field of LED lighting, in particular to an LED lighting circuit and a lighting lamp. Background technique [0002] LED (Light-Emitting Diode, light-emitting diode) light source is the light source of light-emitting diode, which has the advantages of high efficiency and long life. It is widely used in public places such as offices, classrooms, shopping malls, subways and tunnels. The mainstream product of a generation of lighting. [0003] In the current LED lighting fixtures, an isolated AC-DC switching power supply constant current driving method is used to drive the LED module, but this driving method has the problem that the switching power supply has a complex structure and large volume, which leads to high costs. At the same time, multiple electrolytic capacitors are needed in the switching power supply, and the life of the electrolytic capacitors is short, so that the life of the switching power supply is shorter than the l...
