Mercury Vapor lamps come in a variety of wattages ranging from 40-750 W, and have ... 2.2 High Pressure Sodium (HPS) High Pressure Sodium lamps have an efficacy of 90-140 Lumens Per Watt, very long lamp life at 10,000 - 40,000 hours and a short warm up time of 3-4 minutes. At the heart of the lamp is an arc tube which is fabricated from quartz, with a tungsten electrode disposed at either end. Because mercury lamps are so prevalent in current outdoor lighting, and still safe when properly installed in a serviceable fixture, the need for these products will continue for many more years.

Among the light sources in use for general lighting, high pressure mercury vapour (h.p.m.v.) During the last 15 years the luminous efficacy and the colour appearance of these mercury vapour lamps have been much improved by the application of europium-activated phosphors. Most frequently terms . Mercury Vapour Lamps - Dealing With Breakages Some items of laboratory equipment contain mercury vapour lamps to generate UV light. lamps with lamp ratings from 50 to 2000W play an important role in outdoor lighting. The heat generated by the arc then vaporizes the mercury and sodium. Some bulbs also briefly produce a pure to bluish white light in between if the mercury achieves its high pressure arc discharge characteristic before the sodium is completely warmed. Often called germicidal or ozone absorption lamps, they are very stable light sources. This phosphor technology offers better color rendition than the more efficient, high or low-pressure sodium vapor lamps, but still falls short of metal halide and ceramic metal halide sources. This is different from fluorescents which use the mercury vapor arc to create a weaker light that mainly creates UV light to excite the phosphors. Suggestions < Back to product family. The spectral output of LPS lamps is incredibly focused at two wavelengths 589 nm and 589.6 nm. In the mercury lamp, light is produced by the passage of an electric current through a gas or vapor under pressure instead of through a tungsten wire as in the incandescent lamp. The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger borosilicate glass bulb. 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. Lumen Rating SYLVANIA High Pressure Sodium lamps, with the excep-tion of LUMALUX® Super and SOX lamps, are based on burn-ing cycles of at least 10 hours per start and ballasts which meet ANSI standards. Mercury vapor lamps are more For use with control gear designed for high-pressure mercury lamps A lamp breaking is extremely unlikely to have any impact on your health. v׽c�e��z(.X׋����UN�h���h�]-�7��b� ���b����s��ɭc�Ȩ�d ��]��5�Y�� Section Name: Electrical Lamps and their Auxiliaries (ETD 23) Designator of Legally Binding Document: IS 6616 Title of Legally Binding Document: Specification for Ballasts for High Pressure Mercury Vapour Lamps Number of Amendments: Equivalence: Superceding: Superceded by: LEGALLY BINDING DOCUMENT Step Out From the Old to the New--Jawaharlal Nehru 13.3.

Low pressure mercury vapor lamps are a highly efficient source of UV light, particularly short wavelength UV light (254nm and 185nm). High Intensity Discharge Lamps. at room temperature) metallic droplets of mercury can be seen in the lamp … Medium pressure lamps produce the greatest UV output per unit length of lamp of the 3 lamp types.

Preview. /Length 13 0 R In 1959, the development of polycrystalline alumina (PCA) opened a new path to introduce the high-pressure sodium vapor Lamp, as this material is very rarely affected by high pressure and temperature sodium vapor. While many applications are ideal for Mercury vapor lamps, they are being challenged by the higher efficiency and better color balance of metal halide and ceramic metal halide lamps, and LED technologies.
