Description
Technical field
The utility model relates to a kind of ceramic metal halide electricity-saving lamp.
Background technology
Ceramic gold-halogen lamp is AC power work, is in the halide mixed vapour of mercury and rare metal, to produce the luminous discharge lamp of arc discharge, and metal halide lamp is on high-pressure sodium lamp basis, to add the third generation light source that various metal halides are made.
There is the features such as luminous efficiency is high, color developing good, the life-span is long, it is a kind of energy-conservation new light sources that approaches color of sunshine, it is with under equiluminous, can save 40 ~ 55% electric energy with respect to high-pressure mercury lamp, the colour rendering of its high-quality, can be widely used in the room lighting in the places such as stadiums, exhibition center, megastore, industrial premises, square, street, station, harbour.
Inductor is to be the element that magnetic energy stores electric energy conversion. The structure of inductor is similar to transformer, but only has a winding. Inductor has certain inductance, and it only hinders the variation of electric current. If inductor is under the state that does not have electric current to pass through, when circuit is connected, it will be attempted to hinder electric current and flow through it; If inductor under the state that has electric current to pass through, when circuit disconnects it will to attempt to maintain electric current constant. Inductor claims again choke, reactor, dynamic reactor.
Because ceramic metal helide lamp belongs to high-intensity gas discharge lamp, in lamp, be filled with a small amount of metal halide and other gases, so from starting to the normal luminous three phases that needs. 1, the triggering stage: without filament, only has two electrodes in metal halide lamp, directly add that operating voltage can not light, must first add high pressure and make gas ionization in lamp. 2, catch fire the stage: after bulb triggers, the further heating electrode of discharge voltage of electrode, forms glow discharge, and creates conditions for arc discharge. 3, normal glow phase: under the effect of glow discharge, electrode temperature is more and more higher, the electron amount of transmitting is more and more, is transitioned into rapidly arc discharge. Along with temperature further raises, the luminous more and more tetanic of lamp arrives normally. Therefore, ceramic metal helide lamp can not thermal starting, after will waiting luminous courage internal pressure and temperature to decline after extinguishing, just can again start light, run into the timing of instant cut-off or voltage instability, will extinguish and cannot light or the stroboscopic phenomenon such as turn off the light, reduced the reliability of illumination.
Summary of the invention
The purpose of this utility model be to provide a kind of can effectively solve ceramic metal helide lamp extinguish cannot again light, stroboscopic is turned off the light, the excessive problem burning out of electric current, reach certain energy-saving effect simultaneously, make it have more the double-core light courage ceramic metal halide electricity-saving lamp that social application is worth.
The utility model relates to a kind of double-core light courage ceramic metal halide electricity-saving lamp, comprise lamp holder and glass bulb, described glass bulb bottom connects lamp holder, in described glass bulb, be provided with light emitting source, inductor, stem stem, boss, metallic support and conducting bracket, it is characterized in that: described stem stem is installed on glass bulb bottom, and be electrically connected with lamp holder, described light emitting source and inductor are to pass through metallic support, be fixed on stem stem, described light emitting source is two luminous courages of the ceramic metal halide being connected in parallel, the luminous courage of described ceramic metal halide is connected in series with inductor respectively, its lower end of described conducting bracket is connected with the N screw thread power contact head of lamp holder, its upper end is connected with stem stem, described lamp holder connecting electronic ballast.
An electric contact of above-described electric ballast is electrically connected with the L power contact head of lamp holder, and its another electric contact is electrically connected with the N screw thread power contact of lamp holder.
Above-described light emitting source is to be made up of polycrystalline alumina ceramic.
The utility model is that two luminous courages of ceramic metal halide are connected in series with an inductor respectively, then they are connected in parallel. In glass shell, they are fixed on by conducting metal support on the two ends of stem stem, and stem stem upper end is electrically connected with the electric contact of lamp holder, and stem stem lower end is electrically connected with conducting bracket lower end, conducting bracket upper end is electrically connected with screw thread power contact, thereby forms a closed-loop path. In the time starting, because two luminous courages of metal halide are in manufacture process, can there is minute differences, therefore, can cause starting resistor separately to have minute differences, first a relatively low luminous courage of starting resistor can start electric discharge, subsequently, voltage sharply drops to normal working voltage, and the luminous courage of another cannot be lighted because can not get enough starting resistors, in the dormancy stand-by state that opens circuit; When running into unexpected power failure or spread of voltage; the inductor being series in circuit started with regard to moment, release current, the variation of supplemental current; make the just ceramic metal helide lamp in normal work not because of voltage problem instantaneous variation, play the effect of protection ceramic metal helide lamp. Again when power transmission, a luminous courage of before working can be because excess Temperature and cannot starting in courage, and the luminous courage that does not start work before another can normally start light.
Compared with the prior art, its feature and progress are the utility model:
1, solve ceramic metal helide lamp extinguish cannot again light, stroboscopic turns off the light and the excessive problem burning out of electric current.
2, two luminous courages can take turns to operate, and extend ceramic metal helide lamp service life.
3, there is higher colour temperature and colour rendering, reduced more realistically visual color resolution capability.
