The power of the wall washer can reach the effect of washing the wall, but the line lamp will not work, and the line lamp is suitable for contouring. The first is the difference in construction principle: led light, is a kind of light-emitting diode. This type of luminaire converts electricity into light. Energy-saving lamps generally refer to energy-saving bulbs. The top of the energy-saving lamp is the lamp head, and the lower part is the lamp structure.
Secondly, the difference in the principle of illumination: LED lamps rely on LEDs to convert electrical energy into light energy. LED is basically a small LED lamp bead encapsulated in epoxy resin, so it is very small and very light. Led power consumption is very low, in general, the operating voltage of the LED is 2-3.6V. The operating current is 0.02-0.03A. The principle of illuminating the energy-saving lamp: the filament of the lamp is heated by the ballast. At about 1160k, the filament starts to emit electrons (because some electron powder is coated on the filament), and the electron collides with the argon atom to produce an inelastic collision. After the collision, energy is obtained and it hits the mercury atom.
The mercury atom breaks after the energy is absorbed to generate ionization, and emits ultraviolet light of 253.7 nm, and the ultraviolet light excites the phosphor to emit light. The LED is made of a semiconductor material to form a light-emitting diode to directly convert electrical energy into light energy, and its electro-optic efficiency is high.
