PURPOSE: An LED lamp is provided to reduce power consumption by arbitrarily controlling the lighting time of an LED through a variable resistor. CONSTITUTION: A sensor(108) is arranged in an LED lamp(100) to sense the approach of a person or object. A lighting switch(104) is switched by the control of the sensor. The lighting switch turns on and off the LED. A variable resistor(106) arbitrarily controls the lighting time of the LED. A selection switch(102) selects the control method of the LED lamp. |
