Mercury vapour lamp

A mercury -vapor lamp is a gas discharge lamp that uses an electric arc through vaporized mercury to produce light. Free Delivery on Eligible Orders! The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger borosilicate glass bulb. The mercury vapor lamp is a high intensity discharge lamp.

This is different from fluorescents which use the mercury vapor arc to create a weaker light. In case of fluorescent lamp the mercury vapour pressure is maintained at lower level such that of the total input energy gets converted into 253. Again transition of the electrons requires least amount of input energy from a colliding electron. As pressure increases the chance of multiple collisions gets increased. A mercury vapour lamp has at its centre a small quartz arc tube filled with argon gas under high pressure.

This contains a tiny drop of mercury and tungsten electrodes. When electricity passes through the arc tube the mercury is vapourised and emits radiation - heat, light and a great amount of ultraviolet light.

Mercury -vapor lamps are subdivided into low-pressure, high-pressure, and superhigh-pressure lamps according to the operating pressure. Mercury vapor lights consist of a gas-filled glass chamber, protective glass bulb, electrodes and a ballast. The ballast sends electrical power to the electrodes, which excites the gas and makes it glow. The protective bulb filters out harmful ultraviolet light and keeps the mercury gas contained if the inner chamber breaks. The outer bulb can also be coated with phosphor to diffuse the light.

Mercury -vapor lamp definition, a lamp producing a light with a high actinic and ultraviolet content by means of an electric arc in mercury vapor. The clear mercury bulb has a bluish green appearance and the Deluxe White has a higher color rendering.

Mercury lamps get dimmer over time and rarely burn out, so it is wise to replace them and restore light level. We are based in Croydon, South London. Browse our latest mercury - vapour - lamps offers.

Compact fluorescent bulbs save energy but they also contain mercury , a toxic metal. While environmentalists have promoted them as safe, and the US government has given. The second is a mercury vapor arc tube, which takes a few minutes to heat up. There will be a noticeable change in hue (or color) when the bulb is completely warm and fully functioning. Mercury Recycling can provide a range of container options for all types of lamps , fluorescent tubes and batteries.

We can provide containers that are fully-collapsible and containers made of steel and lockable.
