Amalgam lamps use less mercury than standard low-pressure mercury lamps and are RoHS compliant. Under the high-voltage excitation of the power supply, the mercury inside the lamp tube is atomized to emit ultraviolet light, thereby generating spectral lines characteristic of mercury vapor. High-pressure mercury lamps are available in versions where the discharge takes place in vaporized mercury only and in versions in which metal halides are added so that the discharge takes place in mercury vapor and in vaporized metals from the metal-halide components [2, 3]. The second start needs to wait for the lamp body to cool. As the mercury vapor in the lamp further increases, the intensity of the visible spectrum line gradually increases. Weighted energy consumption. The High Pressure Mercury Vapor lamp is a descendant of the Mercury Vapor Lamp, which is an invention of Peter Cooper Hewitt. The high pressure helps increase efficiency and this was developed Although other types of HIDs are becoming more common, mercury vapor lamps are still sometimes used for area lighting and street lighting in the United States.
