Description
Technical field
The utility model relates to a kind of sodium lamp lamp, is specifically related to a kind of compact plasma sodium lamp lamp with how U-shaped inner tube, belongs to technical field of lighting fixtures.
Background technology
Street lamp is that the lighting level of street lamp directly affects the visibility of people to road for providing the device of illumination at night for pedestrian and vehicle.Existing street lamp generally adopts high-pressure sodium fluorescent tube, and low-pressure sodium lamp is the regeneration product of high-pressure sodium lamp; But existing low-pressure sodium lamp requires high especially to light fixture and levelness, angle >=15 °, are attached on filament after the gasification of the sodium metal in lamp more, directly affect the low-pressure sodium lamp life-span, the surface brightness of low-pressure sodium lamp is lower, if, want the illuminance that reaches desirable, need to increase the length of fluorescent tube, for example: if want to make the power of lamp to reach 35W, the length of fluorescent tube will reach 311mm, if want to make the power of lamp to reach 91W, the length of fluorescent tube will reach 775mm.Along with the increase of lamp power, the entire length of fluorescent tube also will increase, and so not only wastes material, more cannot reach the requirement of changing existing street lamp,, because length makes manufacturing cost and installation cost, greatly improves meanwhile, cannot large-area applications and popularization.
Summary of the invention
The utility model is low in order to solve existing low-pressure sodium lamp surface brightness, and the longer problem of entire length, and then a kind of compact plasma sodium lamp lamp with how U-shaped inner tube is provided.
In order to solve the problem that existing low-pressure sodium lamp surface brightness is low and entire length is longer, technical solution adopted in the utility model is:
The compact plasma sodium lamp lamp with how U-shaped inner tube comprises glass outer tube body, lamp holder and U-shaped inner tube, the quantity of U-shaped inner tube is a plurality of, glass outer tube body is sleeved in U-shaped inner tube, and lamp holder is arranged on the afterbody outer end of glass outer tube body, and lamp holder is electrically connected to U-shaped inner tube; In U-shaped inner tube, be filled with inert gas, adopt plasma spraying method to be coated with tin oxide far-infrared reflection film on the inside pipe wall of glass outer tube body, the thickness of the anti-sodium layer of described U-shaped inner tube is less than or equal to 2 μ m.
Plasma spraying aerobic tin far-infrared reflection film on the inside pipe wall of glass outer tube body, have advantages of pollution-free, density is high, and the tin oxide far-infrared reflection film reflectivity forming on the inside pipe wall of glass outer tube body is high, increased the surface brightness of plasma sodium vapor lamp, the plasma sodium lamp lamp of equal-wattage has improved more than 20% than low-pressure sodium lamp surface brightness.
Preferred: the length of described glass outer tube body is between 288 to 355mm, and width is 65-68mm.
Preferred: the quantity of described U-shaped inner tube is three, the rounded layout in cross section of described three U-shaped inner tubes.
Preferred: described in there is the compact plasma sodium lamp lamp of how U-shaped inner tube the top of three U-shaped inner tubes be provided with sodium accumulation point.
Preferred: described inert gas is He-Ne mist.
Preferred: the caliber of described U-shaped inner tube is 16 to 16.4mm.
The utility model compared with prior art has following effect:
The compact plasma sodium lamp lamp with how U-shaped inner tube of the present utility model adopts plasma spraying method spraying tin oxide film, improves the reflectivity of infrared radiation, increases lamp body surface brightness.
Compact plasma sodium lamp lamp, except having included all advantages of low-pressure sodium lamp, has more overcome low-pressure sodium lamp length length and the low shortcoming of surface brightness, is embodied in the following aspects:
1, contraction in length
Length is shaped between 288-355mm, 75-400W high-pressure sodium lamp on the replaceable highway of this length.
2, surface brightness is higher than low-pressure sodium lamp
Owing to adopting plasma spraying method spraying tin oxide film, improve the reflectivity of infrared radiation, increase lamp body surface brightness, the plasma sodium vapor lamp of equal-wattage improves about more than 20% than low-pressure sodium lamp surface brightness.
3, high light efficiency
Because electric light utilance is high, optical efficiency is high, so plasma sodium vapor lamp luminous flux is high, in configuration 30W-36W plasma sodium vapor lamp system, while being used in the street lamp of 8m height, being radiated at ground illumination is 24.5lux; And the street lamp of same height is during with the electricity-saving lamp of 85W, the illumination that is mapped to ground is only 4.4lux.
4, luminous is monochromatic light
Plasma sodium vapor lamp emission wavelength is the monochromatic light for 589.0nm and 589.6nm, the green spectral line that the position of these two yellow spectral lines is 555.0nm near the sensitiveest wavelength of human eye, had both had high luminous efficiency, did not produce again aberration and profound light in human eye, depending on seeing that resolution is high, good contrast.Be more suitable for outdoor public illumination.
5, the little long service life of light decay
Be high pressure sodium lamp and one times of other gaseous discharge lamp or several times the useful life of plasma sodium vapor lamp, is generally 16000-18000 hour.In length of life, light decay is all less than most of light sources, and the fashion of dying of old age can reach 80～85% the logical value of initial light.
6, energy-conserving light source
Plasma sodium vapor lamp is the energy-conserving light source that a kind of luminous efficiency is very high.65W(plasma sodium vapor lamp actual power consumption 68W) light flux ratio 250W high-pressure sodium lamp (actual power consumption 600W) is high by 10%, and therefore, complete available 65W plasma sodium vapor lamp replaces 250W high-pressure sodium lamp, economizes on electricity more than 80%.
7, be widely used
The monochromatic gold-tinted of plasma sodium vapor lamp radiation, color rendering is general, be applicable to the high but illumination place to color rendering no requirement (NR) of illumination requirement, as highway, overhead railway, vcehicular tunnel, bridge, harbour, city square, the bustling location illumination in town and country, high-grade intelligent quarter, embankment, goods yard, building mark and the antitheft illumination of all kinds of building safety, because sodium yellow mist transmitting is strong, this lamp is also suitable for the illumination in foggy region.Electrical source power factor reaches more than 0.95, become real green light source, light source is not subject to the impact of ambient temperature, the brightness of light source is not subject to power-supply fluctuation (voltage up-down) impact, power supply starting voltage level is high, luminous efficiency reaches 200lm/w, energy-conservation the reaching more than 65% of comparing with other energy-conserving light sources.
