3. According to the principle of lighting
Incandescent lamps, gas discharge lamps, electric
Incandescent lamps are the kind invented by Edison that year, and the filament is heated and glows. Also commonly referred to as a light bulb.
The gas discharge lamp means that the electrons collide with mercury atoms to generate ultraviolet rays, and then encounter fluorescent substances to generate visible light. Fluorescent lamps and energy-saving lamps are generally such lamps.
Electroduction means that an alternating voltage is applied to a phosphor to emit light by recombination of electrons. LED (energy saving) lamps are such.
In terms of power and service life, LED lights are more effective in energy saving and use. But in terms of atmosphere, incandescent light bulbs are sometimes used to render the atmosphere.
