The led wall washer light's wattage is relatively larger ,  it can reach to maximum wall washer effect as per  actual requirement of evenironment , with rich color , strong or weak all available ,  intelligent adjustment , but linear light can not do this , it can be contoured in the whole effect,   led wall washer light mainly has long strip type , porous,  different holes can emit different color  light, or the same color light ,or a variety of lights interlaced.  In this way , no matter it is used for building lighting or application of indoor venues , it is more extensive and the effect is excellent .


                                                                         

The large wattage's led wall washer light can reach to wall washering effect ,  linear light can not .  Led light is based on the physical principle diode light ,which convert electric energy to light,  it can save relatively more power than linear light ,  there are also different forms .  envergy saving lamp is mainly light of power saving , lamp head is on top , the lower part is lamp tube structure.  The lighting physical priciple is also different .   Led lighting diode   can convert electric energy to lighting ,  and IED is a basically small chip encapsulated in epoxy resin,   so usually we can not see it because it is really small  and light .  Power consumption is very low ,  easy to install and use , it is also reasonable to be hot in the market .

The lighting emitting principle of linear energy saving lamp is achived by heating the filament of lamp tube through ballast, and with the increase of using time, a certain temperature will be produced. When the temperature reaches about 1160 K, the filament coated with electron powder will start to emit electrons, and when the electrons collide with argon atoms, inelastic collisions will occur. Thus, the energy of argon atom is obtained after collision, and mercury atom begins to collide with mercury atom again. The mercury atom will ionize during the transition process after absorbing energy. Thus, 252.7 mm ultraviolet radiation is found, and ultraviolet radiation will stimulate phosphor luminescence.


The light emitting physical principle of  led wall washer is much easier . The light emitting diode which is made of semicunductors material can directly convert electric energy to lighting energy , and the electro -optic efficiency is very high , meanwhile , it can save power and operate intelligently
