From the principle of illumination, the difference between the above lamps and LED lamps is:
Incandescent and energy-saving lamps are all after converting electricity into heat.
In the process of generating light energy, most of the energy is wasted in this process. LEDs convert energy directly into light energy.
1: light energy (lumen) halogen light flux is generally 20LMW, incandescent lamp is generally 50-60LM/W, LED light flux is generally 80-110LM/W. That is to say, the total amount of light generated by each W light source is quite different, so it can reflect the energy saving effect.
2: luminous efficiency (light efficiency) halogen lighting effect is generally about 30%, energy-saving lamps are generally 60% left
LED lighting can reach 90%, which also brings a big factor in energy saving
LED light flux is more than double that of energy-saving lamps, more than five times that of incandescent lamps, and that 50W LED is equivalent to 110W energy-saving lamps / 250W lamps / halogen lamps.
