First, you use the mechanical energy to power a generator. Then you use the electricity from the generator to power a light bulb. Because the filament is a resistor, it converts enough of the electricity into heat energy to cause the filament to glow.

Are you looking for the quantitative or the qualitative answer?
If you're looking for a simple answer, buy one of those flashlights that you shake. This is what's called induction. Simply put, induction is the act of moving a magnet through a coil of metal creating a flow of electrons, or current. This current can be easily converted to light by using an element that resists the flow of electricity and conversely gives off light, or by using a Light Emitting Diode (LED).
Even simpler: Light a match. You do work to provide the necessary friction and heat to ignite the chemicals on the match, and create light.

Another way - used in those flashing-light shoes made for children and more usefully in sonar and its related fields - is piezoelectricity. A piezoelectric material is one which responds to changing stress hence strain by producing a proportional potential difference (voltage) across it; but the generation occurs only while the strain is changing, and the power / volume ratio is very low.

How does mechanical energy convert to light energy?
One method which this could happen is you have mechanical energy, lets say you riding a bike, and attach a turbine to it which converts your mechanical energy into electrical energy. You then plug a light bulb into that, and the electric energy is converted into light.
How do you convert windnergy into mechanical energy?
how do we convert wind energy into mechanical energy
Is light mechanical energy?
Light is not mechanical energy but it can be transformed into mechanical energy. Light creates an impact as it hits a surface.
Into what kinds of energy does a toaster convert electrical energy?
Mostly heat, and a little bit of light. A lot like an incandescent light bulb.
What does a motor convert?
A motor convert electrical energy to mechanical energy.
The conversion of electrical energy in to mechanical energy?
Motors convert electrical energy to mechanical energy. Generators transfer mechanical energy to electrical energy.
Can television convert electrical energy to mechanical energy?
No
How can you convert chemical energy to mechanical energy?
By burning
How can you convert electrical energy to mechanical sound and heat energy?
We can convert electrical energy into mechanical energy in mixer and grinder. We can convert electrical energy into sound energy in various sound systems. We can convert electrical energy into heat energy in electric water or room heater.
What are four kinds of energy that electricity can be changed into?

How is mechanical energy conserved?
It isn't. Sooner or later some mechanical energy will be wasted and converted to heat. It is also possible to convert other types of energy into mechanical energy.It isn't.

Can you charge battery by mechanical energy?
No. There are, indeed, ways to convert mechanical energy into electrical energy, but a battery is not usually designed to do this. You can convert mechanical energy to electrical energy by another device, but the battery itself has to be charged by electricity.
