Abstract
The utility model relates to a medium illumination sodium mercury lamp. The utility model, a capacitor and a ballast form a circuit system. The medium illumination sodium mercury lamp is provided with an external lamp bulb 2 and sealed space 3 thereof; the external lamp bulb 2 is provided with a lamp cap 1, and the inner wall of the external lamp bulb 2 is coated with fluorescent powder. The utility model is characterized in that a mercury tube core 5 and a medium illumination sodium tube core 4 are installed in the external lamp bulb 2 and the sealed space 3 thereof, and the mercury tube core 5 and the medium illumination sodium tube core 4 are connected with a bracket 8 through a conductive wire 7 which is positioned in a core column 6. The utility model is mainly used for the illumination of indoor and outdoor places such as factory workshops, mine workshops, stadiums, gymnasiums, stations, railways, harbors, worksites, roads, etc.
Description
The utility model relates to and shows Sodium mercury lamp in a kind of.It and starter and ballast or capacitor and ballast built-up circuit system.This lamp has one to be equipped with the external bulb of lamp holder and the space of sealing thereof, and the chamber is equipped with and is shown sodium tube core and a mercury tube core in one within it.
At present, as the sodium vapor lamp that belongs to the third generation than having of advanced person in the glow discharge spot lamp and the fluorescent mercury lamps of the second generation.Sodium vapor lamp structural principle: in translucent ceramic tube, charge into sodium amalgam and rare gas, under External Electrical Field, directly produce the outside width of cloth of sodium characteristic spectrum and penetrate.High-pressure sodium light is higher, good energy saving property, but colour temperature has only 2000K, and colour temperature is on the low side and to be accustomed to photochromic pale yellow difference bigger for people; Color rendering index (Ra=27) is too low.The fluorescent mercury lamps structural principle; Charge into mercury metal and rare gas in quartz glass tube, produce gas discharge under External Electrical Field, mercury element generation ultraviolet spectra converts the outside width of cloth of visible light to by fluorescent material and penetrates.The mercury lamp light efficiency is low, and every watt 40 lumen energy-saving effect is not good enough approximately; Color rendering index is 40, and color rendering is on the low side; Photochromic is cold white, and colour temperature is that the higher visual custom with people of 5600K is not too consistent.Because these shortcomings, above-mentioned two kinds of light sources can only be used for outdoor lighting.
The purpose of this utility model provide photoelectric parameters such as a kind of photochromic, color rendering, light efficiency, life-span all tomahawk in sodium vapor lamp or fluorescent mercury lamps, use with general discharge lamp equally conveniently be specially adapted to room lighting in show Sodium mercury lamp.
Showing Sodium mercury lamp during the purpose of this utility model is achieved in that installs a color rendering index additional show sodium tube core and the series connection of mercury pipe in 60 in fluorescent lamp.Concrete structure: in show sodium vapor lamp and have one to be equipped with the external bulb of lamp holder and the space of sealing thereof.It is characterized in that the external bulb enclosure space is equipped with shows the sodium tube core among a mercury tube core and one.By seal wire in the stem stem and support series connection.
Concrete structure of the present utility model is drawn by the following drawings.
Fig. 1 is embodiment of the present utility model, this embodiment be with the mercury tube core and in show the sodium tube core and be emitted on a together external bulb inner chamber, circuit is for being connected in series.Fig. 2 is the utility model working circuit diagram.
Below in conjunction with accompanying drawing concrete structure of the present utility model and working condition are further described.
Referring to accompanying drawing 1,2: showing Sodium mercury lamp in the utility model has an inwall that is equipped with lamp holder 1 to scribble the external bulb 2 of fluorescent material and the space 3 of sealing thereof.It is characterized in that being equipped with in the external bulb sealing 3 and show sodium tube core 4 and mercury tube core 5 and the seal wire 7 by stem stem 6 and support 8 in one and be in series and be fixed on external bulb 2 inner chambers.In show Sodium mercury lamp and ballast 11, capacitor 10 built-up circuit systems.Its profile can be elliposoidal, olive shape or other form.
According to above-mentioned composition dress form in show its operation principle of Sodium mercury lamp and be: AC power through ballast 11, capacitor 10, lamp holder 1, stem stem seal wire 7, mercury tube core and in show the sodium tube core and send distinctive spectrum separately, fluorescent material is converted to visible light with the ultraviolet light of mercury tube core on the one hand.On the other hand because its reflex.The spectrum of two kinds of tube cores is fully mixed in lamp.Give off mixed spectra.This Sodium mercury lamp even light mixing, photochromic, color rendering, the light efficiency of showing in just making, the life-span all is better than mercury lamp or sodium vapor lamp, and use is the same with sodium vapor lamp convenient, thereby reaches the purpose of this utility model.
The utility model compared with prior art has high every watt 80 lumen of luminous efficiency, and is photochromic good, and look wet is 3300K-3500K; Color rendering is good, color rendering index is 65-70.Have the life-span long (average life span 10000 hours) in addition, characteristics such as energy savings, comprehensive technical indexes is higher than existing high-pressure discharge class light source, can partly replace mercury lamp and sodium vapor lamp is used for indoor and outdoor lighting.
