Description
Technical field
The present invention relates to a kind of electric light source, particularly low-pressure sodium lamp.
Background technology
Low-pressure sodium lamp is the electric light source products that utilizes low pressure sodium vapor arc discharge principle to make, it has energy efficiency height, long characteristics of life-span, during work, at two extremely strong yellow line light sources of visible region radiation, claim the D two-wire again, their wavelength is respectively 589.0nm and 589.6nm, gets the standard wave length parameter of its mean value 589.3nm as sodium yellow usually.Existing low-pressure sodium lamp mainly comprises the coaxial discharge tube that is arranged in the transparent outer glass bulb, is filled with inert gas and sodium metal in the discharge tube, and discharge tube the two poles of the earth are provided with electrode, and outer glass bulb is the photoelectric type glass tube, shields; Discharge tube through bracing frame with outside glass bulb fix.In a period of time after the low-pressure sodium lamp energising is light, sodium light is carried along with temperature rises and is increased gradually, and when being stabilized in 260 ℃ as if wall temperature, sodium light is carried and reached optimum value.Therefore, the speed that the discharge tube temperature rises is a key factor, and discharge tube is a straight tube in the existing low-pressure sodium lamp, and radiating surface is big, light compile weak effect, can only be used for spectrum analysis, can't be used in other illumination occasions.Sodium atom is that the silicate glass of main material has strong erosion to SiO2 under 260 ℃ working temperature, makes transparent glass become dark brown, under the sodium atom corrosion function, can reduce light efficiency, and the use persistence of existing low-pressure sodium lamp is poor.
Summary of the invention
Purpose of the present invention provides the low-pressure sodium lamp that can overcome above-mentioned defective, and it is short that it was started to the steady operation time, the fluorescent tube volume adequacy, and the light efficiency height can keep high light efficiency lastingly.
For solving the problems of the technologies described above, low-pressure sodium lamp provided by the invention, comprise the discharge tube that is packaged with inert gas and sodium metal, discharge tube is arranged in the outer glass bulb of cylindrical shape transparent cylinder shape of high vacuum, discharge tube through bracing frame with outside glass bulb fix, discharge tube the two poles of the earth are provided with electrode, and described discharge tube comprises anti-sodium jacking glass-tube, is shaped as the U type; Anti-sodium jacking glass-tube is made up of the anti-soda barium glass layer of outer field silicate glass layer and internal layer.
Because sodium atom is the silicate glass strong erosion of main material at 260 ℃ to SiO2, make transparent glass become dark brown, the present invention has effectively stoped the sodium atom erosion by the anti-soda barium glass in the setting of flashed glass inner tube layer, ensured simultaneously the high light transmittance of discharge tube again, can make the high light efficiency of the lasting maintenance of the present invention.Compared with prior art, U type discharge tube structure compactness makes outer glass bulb volume little, and radiating surface is little, and temperature rise is fast, and compiling of light is effective, and lamp can make the discharge tube wall temperature be stabilized in 260 ℃, its light efficiency height in 10-15 minute after starting; The present invention is applicable to multiple illumination occasions such as road, tunnel, harbour, warehouse; Can carry out complementation with light source and form white light with blue light.
Be reliably fixedly discharge tube, described bracing frame comprises first bracing frame and second bracing frame, and first bracing frame made from metal material is arranged on the bending end of U type discharge tube, and second bracing frame made from mica is arranged on the openend of U type discharge tube.At first bracing frame middle part, be designed to the sphere that is complementary with U type discharge tube bending end, the hole has been reserved at the first bracing frame center, and the blast pipe of U type discharge tube bending end setting passes this hole.In the system lamp process, by blast pipe pump drainage gas, pump drainage rear enclosed blast pipe, for U type discharge tube, blast pipe can be arranged on the bending end, and above-mentioned design plays well secured, cushioning effect to discharge tube, is beneficial to transport and install and use.Because sodium atom moves to low-temperature region after outage easily.The low-temperature space of this lamp is just at the two poles of the earth sealing part, and after work a period of time, sodium atom can be deposited in discharge tube the two poles of the earth sealing part, and when switching on once more, positive column sodium atom density is low, and start-up time is long; Making the middle part with the good metal of thermal conductivity is first bracing frame of sphere, after the fluorescent tube outage, the first bracing frame heat conduction is fast, can make the U type bending end of discharge tube form a cold well, sodium atom during rapid collection is hot makes the heavy center of gathering at the discharge positive column of more sodium atom.Solved the short life problem that " sodium depletion " causes effectively.
On the described outer glass bulb inwall infrared reflection light-transmissive film can be set, on the infrared reflection playback fulgurite wall that it can give off discharge tube, effectively improve tube wall temperature, it is reached as early as possible and remain on 260 ℃ of warm areas; Can effectively see through the visible light of 589.0nm again; Reduced outer glass bulb temperature simultaneously.
As a further improvement on the present invention, described electrode is the moulding of fried dough twist type triple helical, and is arranged on the home position at U type discharge tube the two poles of the earth.Electrode is twist shape and has bigger electronics powder reserves, can successfully solve the contradiction between discharge tube minor diameter and the big operating current.
