Three lights "war" who will be unified lighting lakes

Can a variety of light bulbs on supermarket shelves make you take a look? Faced with "assorted" incandescent lamps, energy-saving lamps with the most "artistic fan", and LED lamps with the "high-manufactured" lamp in the bulb industry, you can clearly tell the difference between them and how they work. Are their respective advantages and disadvantages? If you are hesitant, Xiao Bian will take you into their world to understand what the difference between them is, and which one is more suitable for our social energy environment and life use scenarios.

Three lights "war"

First, the "fate" dispute

1. Incandescent lamp - life is 1000 hours

Advantages: easy to manufacture, low cost, quick startup, simple circuit, small light source, a wide variety of lampshades, and light fixtures, ceilings and wall mounting fixtures and concealed devices, versatility, color variety , with orientation, scattering, diffusion and other forms, can be used to enhance the three-dimensional object, incandescent lamp color is closest to the color of sunlight.

Disadvantages: No environmental protection is the biggest drawback. When using incandescent lamps, 95% of the electrical energy is spent on heating. Only 5% of the electrical energy is actually converted into light we can see. Low luminous efficiency, high heating temperature, fast heat evaporation, short life (1000 hours), high infrared content, easy vibration, low color temperature, yellow color.

2, energy-saving lamps - life of more than 6000 hours

Advantages: The energy conversion rate is much higher than that of incandescent lamps, which saves energy. It can also be said to reduce greenhouse gas emissions and has a long service life.

Disadvantages: The price is relatively high as well as the energy-saving lamps and lamps are inadvertently broken mercury volatilization, which has great harm to the human body.

3, LED lights - life of more than 20,000 hours

Advantages: LED lamp energy-efficient, only a few hours of electricity consumption in one thousand hours; lamps long life, semiconductor chip light, no filament, no glass bubbles, not afraid of vibration, not broken; the light does not contain ultraviolet and infrared, no radiation; Does not contain harmful elements such as mercury and helium, which is conducive to recovery, and will not produce electromagnetic interference; DC drive, no flicker, can protect eyesight; high safety factor; market potential, can be used for remote mountain areas and field lighting and other power shortages, less Electric fields and so on.

Disadvantages: LED lamps under the AC drive and ordinary incandescent lights will have the same strobe phenomenon, and ordinary energy-saving lamps do not have strobe phenomenon. Strobe will make the eyes easily fatigued; each led bulb light is too bright, it will strongly irritate the eyes, can not look directly, even for a short time, and ordinary energy-saving lamps are relatively softer; irradiation angle is limited, generally only 120 ° , And ordinary energy-saving lamps can be irradiated almost 360 °; the brightness of the illuminated room is not better than the energy-saving lamps, because the LED only has high brightness within a narrow angle of the direct view, and after the deviation of the angle, the light quickly weakens.
