Flashlight bulbs

 

There are several bulbs can be used as a flashlight light source now. They generally fall into three categories: the incandescent type, LED (light emitting diode) and fluorescent type.

Incandescent bulb filament glows when it is heated to near the melting point. When the electricity is sufficient, the bulb shines relatively strong light, when the electricity decreases, the filament gets cold and the light fades and become yellow, and completely out when the power is run out.

LED can directly convert chemical energy into light. LED has quite high powert-conversion in the use of low power. When the electricity is running out, LED keeps the brightness for a certain time but not get yellow.

Fluorescent bulbs glow by using the energy emitted by the filament to hit the fluorescent substance in the bulb to produce light. This kind of light is a soft arealight source, which cannot be used as a point light source.
