LUMALUX Super and SOX lamp ratings are based on measure-ments at constant input voltage. For some lamps these data sheets are contained in this standard. The mercury vapor lamp is a high intensity discharge lamp. In these types of lights the inside of the tubes are coated with a coating of fluorescent phosphor which emits visible light when the arc establishes and the gas inside ionizes. 2. Construction:- It consists of an inner bulb generally of silicon, to withstand high temperatures. Liquid mercury droplets collect at the lamp’s “cold spot.” Once the mercury droplets reach their … This radiation is certainly detrimental for the health of human beings as well as any pet animals in the house. Further improvement is achieved in many of the lamp types by the addition of a phosphor coating to the inside surface of the outer bulb. Still it might take quite some time before these are stopped from being manufactured or used in most other parts of the globe. High-pressure mercury vapour lamps . This rectification is done by applying phosphor on the inner surface of the bulb. After that the arc then heats up the mercury and the mercury vapor then lights, giving the lamp a bluish color. Three primary lamp types comprise the family of industrial HID lamps. Due to the simplicity of construction and design this makes this type of lamp the lowest price, lowest cost-per-Watt, and highest intensity source available on the market. Most modern mercury vapor lamps have this rectification done in them. High Pressure Sodium. Since the light emitted by a mercury-vapor light has a blue tone, this needs to be accounted for, or color- corrected as it is called. Table 1 compares each lamp according to several features . They are available in lengths from the very small at 150 mm to up to 2400 mm. Mercury Vapor. The tube is filled with mercury and argon. As already mentioned in the introduction to this book, the high pressure mercury vapour lamps which existed in the years before 1930 were almost solely used as U.V. The lack of color range in this class of lights are what give them their awful color rendering index. The same wattage metal halide lamp produces 40,000 initial lumens, and the 400-watt mercury vapor lamp produces only 21,000 initially. A big driver behind their use is their… The HPS lamp consists of a narrow arc tube supported by a frame in a bulb. Super high pressure mercury capillary flash lamps are used in a variety of applications due to the fact that they provide a high intensity source of both visible and ultraviolet radiation. As pressure increases the chance of multiple collisions gets increased. The gas and electrodes are contained within an optically transparent, elliptically shaped envelope (or bulb) composed of fused silica (see Figure 2). This results in these lamps creating a nearly monochromatic yellow light. For example, a 400-watt high pressure sodium lamp produces 50,000 initial lumens. Jelight Company also produces super high pressure mercury lamps or short arc lamps. The pressure inside the lamp is around 0.3% of atmospheric pressure. Does it mean that the potential of mercury vapor lamps to cause debilitating effects on health could turn out to be its stumbling block in its wide scale usage? Are similar in construction to sodium vapour lamps . High-pressure sodium lamps (also known as HPS Lamps or HPS lights) are a type of sodium lamp that is widely used in industrial lighting and many public outdoor areas. A xenon arc lamp is a highly specialized type of gas discharge lamp, an electric light that produces light by passing electricity through ionized xenon gas at high pressure. They are commonly used in public parking lots, roadways, and other security areas. The arc tube has a high pressure inside for higher efficiency. A. This results in a warmer color appearance and higher color rendering than standard mercury lamps. It also needs to be underlined that mercury is not the only evil in the mercury filled lamps, but other chemicals present in the bulbs have the potential to cause sufficient damage to health.
