What are the two specific lights of high pressure sodium lamp and high-pressure mercury lamp?
High pressure sodium lamp and similar low pressure sodium lamp, mainly composed of filaments, bimetal thermal relay, discharge tube, glass shell, etc., it consists of translucent polycrystalline alumina ceramic material, filled with mercury and mercury sodium agent, mercury vapor to produce high pressure, made of tungsten filament filament spiral or woven into a can storage of alkaline earth metal oxides of a certain number of shape, when the bulb is started, the arc tube arcing between the electrodes at both ends, due to the high temperature the effect of arc tube sodium mercury vapor evaporation as mercury vapor and sodium vapor emitted from the cathode to anode electrons in the movement process, impact discharge atomic material to obtain. Energy ionization or excitation, and then by the excited state back to the ground state; or by the ionized into an excited state to the ground state, then an infinite loop, at this time, the excess light energy to radiation Form release gives birth to light.
High pressure mercury lamp is a high pressure mercury vapor discharge lamp with fluorescent powder on the inner surface of glass bulb. It has a soft white light and simple structure. Low cost, low maintenance cost, can directly replace incandescent lamp, light has long effect, long service life, the characteristics of power saving economy, suitable for industrial lighting, warehouse lighting, street lighting, flood lighting safety lighting etc.. Red does not contain high pressure mercury lamp light irradiation, it objects blue, it is only suitable for square and street lighting. Except for the high pressure mercury lamp for general lighting purposes, and with reflective film on the outer reflection type lamp (HR), for 300 ~ 500nm diazo paper copy lights, advertising, display with black light, erythema effect for medical use as sun light, nylon material photosynthetic chemical and paint, ink with the dry polymerization UV mercury lamp etc..
High pressure sodium lamp and high pressure mercury lamp are all lights, with various models and specifications. Used for lighting of roads, factories and mines, stations and docks. The light emitted by the high-pressure sodium lamp is yellow, and the light emitted by the high-pressure mercury lamp is white.
