How home light bulbs work
-
The lighting of the light must be inseparable from the composition of the light bulb, which plays a very important role.indoor led lighting， How does that light bulb work?
The working principle of the light bulb is made according to the principle of thermal effect of electric current. After the bulb is connected to the rated voltage, the current passes through the filament and is heated to an incandescent state (above 2000C), so it emits heat and converts electrical energy into internal energy and light energy during operation. And light is a form of energy that is released by atoms.
It is made up of many tiny clumps of particle-like things that have energy and momentum but no mass. These particles, called visible photons, are the most basic unit of light. Atoms emit visible photons when electrons are excited.
