Why is LED (Light Emitting Diode) technology considered superior to traditional incandescent bulbs?
- LEDs convert a higher percentage of electrical energy into light rather than heat.
- LEDs produce light through the heating of a metal filament.
Choose the correct option from the following.
Correct answer: A
Explanation
Statement 1 is correct: LEDs convert a much higher share of electrical energy into light and waste far less as heat, which makes them far more efficient. Statement 2 is wrong because producing light by heating a metal filament describes the incandescent bulb, not the LED. An LED emits light when current passes through a semiconductor.
