A high voltage is utilized across electrodes sealed into every end of the tube to offer the luminous effect by exciting the gases trapped within the tube. To acquire a wider range of colours, the glass tube can be coated with fluorescent phosphors, which convert the ultraviolet radiation from the mercury or neon into seen mild. The excessive voltages are achieved through the use of step-up transformers.Electrical shock is a risk largely when the sculpture is connected to its bombarding transformer to take away impurities from the glass tube, or to its electrical power source for testing or show (figure 96.4). The electrical present passing by way of the glass tube additionally causes the emission of ultraviolet mild that in flip interacts with the phosphor-covered glass to kind colors. Some near-ultraviolet radiation might pass via the glass and current a watch hazard to those nearby; subsequently, eyewear that blocks UVA must be worn.
