The simplest way, which is fairly inefficient, is to heat something up until it glows. This is done in the old-fashioned incandescent light bulbs; due to their inefficiency, many countries are seriously considering outlawing them.
Other options include exciting atoms by passing a current through them. Excited means that individual electrons are raised to a higher energy level; when they "fall back down", they release light energy. This happens both with the fluorescent lamp and with the LEDs.

Can electrical energy change into chemical energy and light energy?
Yes, electrical energy can be used to drive chemical reactions in a battery to store energy in the form of chemical energy. Additionally, electrical energy can be converted into light energy by passing an electric current through a light bulb or LED.
How does energy change in a flashlight?
Energy in a flashlight changes from stored chemical energy in the battery to electrical energy when the battery powers the light bulb, which then converts electrical energy into light and heat energy.
What is the energy change that occurs in a light bulb?
The energy change that occurs in a light bulb is primarily the conversion of electrical energy into light and heat energy. When the electrical current flows through the filament in the bulb, it generates heat which causes the filament to glow and emit light. This process involves a transformation of energy from one form (electrical) to another (light/heat).
How does energy change form in a flashlight?
In a flashlight, electrical energy from the batteries is converted into light energy and thermal energy. The electrical energy flows through the circuit to power the light bulb, which emits light energy. Some of the electrical energy is also converted into thermal energy due to the resistance in the circuit and the light bulb filament.
How does a television change to electrical energy into light energy?
A television screen contains millions of tiny light-emitting diodes (LEDs) or liquid crystals that emit light when an electrical current passes through them. The electrical energy powers these components, causing them to emit light and display images on the screen.

What is the energy change in a LED?
In a LED, electrical energy is converted directly into light energy, resulting in a decrease in electrical energy and an increase in light energy. This process is much more efficient than traditional incandescent bulbs, which waste energy as heat.

What is the change of electric energy to light energy called?
Light energy is electrical energy thus no change. Radiation is a form of electrical energy. Light Energy E=hf = hc/r = zQ^2c/r = Q^2/r*epsilon, where Planck's Constant h= zQ^2.
As charge flows in a circuit some electrical energy always change to what energy?
light energy :) ANSWER: THERMAL ENERGY
