Led lamp-lighting circuit and led lamp as well as an led lamp-lighting conversion socket

An LED lamp, comprising:

• an LED lamp-lighting circuit connected to an AC power supply and having a current rectifying circuit for rectifying the AC power supply,
• an LED driver connected to an output side of said lamp-lighting circuit and receiving a DC voltage from the current rectifying circuit,
• an LED that is driven by said LED driver,
• a start-assist circuit that is connected in parallel to an output side of the current rectifying circuit, and has at least a capacitor and into which excessive current flows for a specific time after the power supply has been turned on,
• a fixed current load circuit that is connected in parallel to the LED driver and into which a fixed current flows and
• a current stopping circuit that stops the current from flowing into the fixed current load circuit when current flows into the LED driver.

A conversion socket for connection between an LED lamp unit, having an LED and an LED driver that drives said LED, and an AC power supply for lighting the LED, comprising:

• a built-in LED lamp-lighting circuit having a current rectifying circuit that rectifies AC power and supplies DC voltage to the LED driver,
• a start-assist circuit connected in parallel to an output side of said current rectifying circuit which contains at least a capacitor and into which excess current flows for a specific period of time after the power supply is turned on,
• a fixed current load circuit connected in parallel to the start-assist circuit and into which a fixed current flows, and
• a current stopping circuit that stops current from flowing into the fixed current load circuit when current flows into said LED driver.
