What is the difference between a high pressure mercury lamp and a high pressure sodium lamp?

- Nov 01, 2018-

High-pressure mercury lamp is a high-pressure mercury vapor discharge lamp with phosphor powder on the inner surface of the glass bulb. It has soft white light and simple structure. Single-ended gas-filled bulb with quartz mercury vapor discharge tube.

The blue-white luminescence provided by the inner coated oval external bulb has a reasonable light quality.

Low cost, low maintenance cost, can directly replace ordinary incandescent lamps, with long luminous efficiency, long life, and economical economy.

Suitable for industrial lighting, warehouse lighting, street lighting, flood lighting, safety lighting, etc.

The high-pressure sodium lamp source has high luminous efficiency and a transparent straight tube type casing; the light source discharge tube is filled with a sodium-mercury mixture and a starting gas crucible;

The utility model has the advantages of high luminous efficiency, low power consumption, long life, strong fogging ability and no attracting insects. Widely used in roads, highways, airports, terminals, docks, stations, squares, street intersections, industrial and mining enterprises, parks, courtyard lighting

Different configuration: high-pressure mercury lamp with ballast can be energized, no need to be equipped with triggers, capacitors and other electrical accessories, self-ballasted mercury lamps, no need to pick up any electrical appliances, can be directly powered when connected to the power supply, simple and convenient, cost-saving .

High-pressure sodium lamps must be equipped with ballasts, triggers, capacitors and other electrical accessories for normal use. They have high luminous efficiency, long life and reduced maintenance costs.
