The present invention provides an LED lamp, in which a resistor is mounted in parallel to each of LEDs, so a residual electrical current may be prevented from flowing in the LEDs. Accordingly, an afterimage occurring when the LED lamp is extinguished is removed, so quality of a lamp may be improved. Moreover, according to the present invention, various adjacent LEDs, for example 2-4 LEDs, are linearly connected in parallel with one resistor, and a residual electrical current may be prevented from flowing in LEDs, so an afterimage is effectively removed and a circuit may be easily structured to improve effects. Furthermore, the present invention also provides an LED lamp capable of removing an afterimage, wherein various LEDs and a resistor are produced in an LED bar shape, and LED bars are connected in parallel, so an LED lamp is produced and various kinds can be produced and purchased corresponding to required light-emitting capacity of a lamp. According to the present invention, a resistor used in removing an afterimage has 4.7-100.0 kΩ, so a resistor may be easily produced and mass-produced. Consequently, production costs of an LED lamp are reduced and mass-production is possible. |
