What’s the the structure of high pressure sodium lamp?

High pressure sodium lamp is a variety of high intensity gas discharge lamp. Using high-pressure sodium lamp a golden white light, with luminous efficiency, less electrical power consumption, prolonged service daily life, by means of fog and luring etc. positive aspects. Widely utilized in road, highway, airport, dock, dock, station, square, street intersection, industrial and mining enterprises, parks, backyard lighting and plant cultivation. Higher shade high-pressure sodium lamp is largely utilized in gymnasium, exhibition hall, amusement parks, division retailers and hotels and also other locations lighting. High pressure sodium lamp discharge materials vapor pressure is extremely large, namely large atomic density of sodium, sodium atoms and electron collision among the number of frequent, the resonance radiation broadening of spectral lines and various visible spectrum of radiation, so the high-pressure sodium lamp light shade is much better than that of reduced stress sodium lamp.

Wick could be the use of metal stents will arc tube and getter ring and fixed on the column, the arc tube at the two ends with the electrode are respectively connected with columns with two inner guide wire. The core is composed of a guidebook wire, the exhaust pipe and the horn by higher temperature flame fused into a single. The metal guidebook wire and glass sealing a part of the connection of your growth coefficients ought to be matched with, can stay away from the 2nd sealing materials expansion coefficient is not really the identical, resulting in sealing glass anxiety and burst or lighting persistent air leak.

Glass will be the selection of higher temperature really hard glass manufacturing. Glass shell plus a wick trumpet by substantial temperature flame melting sealing, then evacuated or filled with an inert fuel, and then loaded to the total lamp head lighting primary form. Because of the high temperature from the arc tube, the bare metal is incredibly simple to oxidize and brittle, and it must be placed while in the vacuum or inert gasoline. It could also decrease the heat loss on the arc tube, strengthen the cooling finish temperature, and improve the luminous efficiency

The lamp holder’s perform would be the circuit connect the hps bulbs. The long-life bulb necessitates the lamp holder along with the glass shell must be firmly connected, no loosening and shedding phenomenon. Therefore, the standard use of thread mechanical fastening engineering, can avert welding mud all-natural aging and fall off. Manufacturing of the lamp cap elements commonly used brass band, and lamp holder to help keep smaller sized contact resistance, minimize metal oxide layer around the surface. In case the bulbs used in the special atmosphere, but in addition from the brass lamp surface coating layer or possibly a nickel chromium layer. The model is: E27 lamp holder, E40 socket
