Abstract
The utility model discloses a sodium lamp, which comprises a lamp cap and an outer quartz glass casing filled with nitrogen, wherein the lamp cap is connected with the outer quartz glass casing. The sodium lamp also comprises a semi-transparent ceramic discharge tube filled with mixed gases of sodium, mercury, xenon, neon and argon, wherein a main electrode is arranged at one end of the semi-transparent ceramic discharge tube, and an auxiliary electrode is arranged at the other end; and the auxiliary electrode is connected with a gas eliminating device through a conducting wire. The sodium lamp provided by the utility model has the advantages of highlights rate and long service life.
Description
Technical field
The utility model relates to a kind of illuminace component, is specifically related to a kind of sodium vapor lamp.
Background technology
At present, the standard type NG1000 type high-pressure sodium lamp of domestic use has lamp holder and lamp housing, inside is provided with electric arc tube, and the electric arc tube two ends are provided with two combination of electrodes, and carries out the vacuum-tightness sealing-in, put into the Na Hg of certain proportion weight in the electric arc tube, charge into the inert gas of certain pressure, the modulating voltage of NG1000 type high-pressure sodium lamp be 110+/-20V, operating current is about 10.3A, the circuit load electric current is big, lamp housing is a cylinder, and the space is little, and light is logical and light efficiency is lower.
Summary of the invention
At above-mentioned technical problem, the utility model provides the sodium vapor lamp of a kind of high light rate, long service life.
The technical scheme that realizes above-mentioned purpose is as follows:
A kind of sodium vapor lamp, comprise lamp holder, be filled with the outer quartz crust of nitrogen, lamp holder is connected with outer quartz crust, comprise that also inside is filled with the translucent ceramic discharge pipe of sodium, mercury and xenon and neon argon mixture gas, one end of this translucent ceramic discharge pipe is provided with main electrode, the other end is provided with auxiliary electrode, and auxiliary electrode connects the device of cooling down by lead.
Be provided with support in the outer quartz crust, the translucent ceramic discharge pipe is fixed on this support.
The described device of cooling down is a box body that getter is housed, and this box body is provided with through hole.
Adopted such scheme, comprised that also inside is filled with the translucent ceramic discharge pipe of sodium, mercury and xenon and neon argon mixture gas, an end of this translucent ceramic discharge pipe is provided with main electrode, and the other end is provided with auxiliary electrode, and auxiliary electrode connects the device of cooling down by lead.The utility model utilizes pressure luminous up to the sodium vapor discharge of 10000Pa, and its spectrum concentrates on human eye sieve and is responsive interval, so its light efficiency is than NG1000 type high-pressure sodium lamp height, and the life-span is long.
