The difference between Incandescent bulbs and LED bulbs: -- Lighting principle -- Incandescent bulbs Heat is generated when current passes through the filament, and the spiral filament continuously gathers the heat, making the temperature of the filament reach above 2000 degrees Celsius. When the filament is in an incandescent state, it emits light like red hot iron. Disadvantage: 1. The incandescent lamp made of tungsten filament lamp is too high in temperature during the lighting process, which may easily cause the product to be burned out, and the safety factor is low. 2. High heat radiation. The greater the power, the more heat. Part of the conversion of electric energy is light, and part is heat. 3. The light emitted by incandescent lamps is full color light, but the composition ratio of each color light is determined by the luminescent substance and temperature. Unbalanced proportions cause to a color cast of light. LED bulbs: When the current acts on the chip through the wire, the electrons and holes will be pushed to the quantum well, and the electrons will recombine with the holes in the quantum well, and then energy will be emitted in the form of photons. Advantage: 1. LED bulbs have lower power consumption and cooler touch, lower watt but higher brightness. 2. LED electric energy converts light energy, which produces little heat radiation, and most of the energy is directly converted into light energy. Also coupled with the heat dissipation structure. 3. LED is a green light source, driven by direct current, have no strobe, and have no infrared and UV components, no radiation pollution, relatively high color rendering and strong luminous directionality.
