 Six light 
 1, light source 8 is rated at 40W Philips fluorescent UV light source for hair. UV fluorescent tubes, located on both sides of the machine on each side 4. With UVA-340 and UVB-313 light source for the user to select the configuration. (Choose one) 
 2, UVA-340 lamp emission spectrum energy is concentrated in the wavelength 340nm 
 3, UVB-313 lamp emission spectrum mainly in the vicinity of 313nm wavelength. 
 4, the fluorescent light energy output will gradually decay over time, in order to reduce the attenuation of light caused by the impact test, so the chamber in all eight lamps in every 1 / 4 of the fluorescent lifetime, by a new branch replaces an old lamp tube, so that UV light source is always new and the old lamp from the composition, resulting in a constant output of light energy. 
 5, lamp life can be effective at 500 hours 
 Seven spray control 
 1, spray uniformity of regulation: the use of the controller manual control functions, observed in the open state spray performance, and thus to adjust or replace the nozzle. 
 2, spray condition monitoring: a spray device configured machine, spray device simulation of changes in temperature when it rains and water erosion, a total number of nozzles, spray evenly. When spraying, spray long, set free by the customer. 
 3, the user pressure to be prepared in deionized water. 
 Eight security guards
