PROBLEM TO BE SOLVED: To provide an LED lamp.SOLUTION: The LED lamp according to the embodiment of the present invention, comprises: a light source part including at least one LED; and a light source driving part which is connected to the light source part, is connected to a commercial AC power supply and a magnetic type or an electronic type stabilizer for a fluorescent lamp, converts an applied AC power source applied thereto into a DC power source, and drives at least one LED by applying the power source to the light source part. The light source driving part includes: a power source terminal part which can be connected to or disconnected from the commercial AC power supply, and the magnetic type or the electronic type stabilizer; a rectification part which is connected to the power source terminal part and rectifies the AC power source applied through the power source terminal; a filter part which smooths the power source outputted from the rectification part, converts it to the DC power source, and applies it to the light source part; and a constant current control part which is connected to the light source part, is operated by the application of a remaining power source voltage consumed by at least one LED of the DC power source applied to a high power source voltage terminal of the light source part, through a low power source terminal of the light source part, and allows the constant current to be flowed in at least one LED.SELECTED DRAWING: Figure 5 |
