Description
Technical field
The present invention relates to a kind of high-intensity gas discharge lamp, particularly a kind of superhigh pressure projection lamp.
Background technology
The superhigh pressure projection lamp claims again UHP, and full name is Ultra High Performance, belongs to the ultra high pressure mercury bulb, its life-span is longer, general 100/120W nominal 8000 hours, the longest even nominal 12000 hours, brightness obvious decay can not occur yet after 4000 hours operating times of accumulative total; 200/250W useful life is about 3000 hours.Superhigh pressure projection lamp (hereinafter to be referred as UHP) can produce large light quantity, and can effectively suppress the generation of the situation of glimmering, and profile is smaller and more exquisite, and brightness decay is less, and the life-span is longer.
Because the only desirable cold light source that the UHP bulb sends so existing generally being applied in just thrown on projector and DLP and the LCD rear-projection combination, also is applied on the family expenses large screen back projection TV.The UHP lamp provides the light source guarantee for the development of projector.
The characteristic of UHP is as follows:
1.UHP product can inspire high brightness, mean value is up to 1Gcd/m2.
2.UHP product is the system of full blast, the short spacing electrode can be applied to the panel of smaller szie.
3.UHP product has very long useful life, light source life can reach 1000 to 6000 hours in front throwing application.
4. by the pulse of ballast generation and the interaction between the light source, effectively stabilized electrodes suppresses the generation of flicker.
5. length of life, the UHP product has stable, complete chromatogram.
At present, the trend of projector's development is miniaturization, energy-saving, high brightness.Based on this trend, to the specification requirement of UHP bulb good warm start performance and the luminous efficiency of Geng Gao just need to be arranged.At the warm start aspect of performance, traditional UHP product can only provide very high peak value starting resistor (about 24kV) to realize by driving power; Aspect luminous efficiency, the axiality between the pole span of UHP electrode and two electrodes plays very important effect, the luminous efficiency that nearer pole span and the axiality of Geng Gao can both improving products.
In the tradition UHP product, two electrode outer ends being located in the airtight quartz outer tube join with two sealing-in molybdenum sheets respectively, and two sealing-in molybdenum sheets are generally the flat sheet-like structure, are easy in actual use be subjected to External Force Acting generation deformation, and then affect two electrode axialities.And the flat sheet-like structure of two sealing-in molybdenum sheets, the UV ray that the ultraviolet auxiliary actuating apparatus is produced enters spherical lamp housing help seldom.
Summary of the invention
The present invention newly provides a kind of superhigh pressure projection lamp, to solve the high technical problem of above-mentioned superhigh pressure projection lamp UHP product peak value starting resistor under the prior art.
A kind of superhigh pressure projection lamp of the present invention, comprise an airtight quartz outer tube, two electrodes and two sealing-in molybdenum sheets, and ultraviolet auxiliary actuating apparatus, the middle part of described quartz outer tube is spherical hollow lamp housing, one end of described two electrodes all is arranged in this sphere hollow lamp housing, be provided with spacing between described two electrodes, the other end of any one electrode is connected with a described sealing-in molybdenum sheet separately, described two sealing-in molybdenum sheets lay respectively in the airtight quartz outer tube, it is characterized in that: the cross section of described two sealing-in molybdenum sheets is trapezium structure, and two interior angle ɑ are 90 °＜ɑ＜180 °.
Preferably, the cross section trapezium structure two interior angle ɑ of described two sealing-in molybdenum sheets are ɑ=120 °.
The present invention and the contrast of existing UHP product:
1, warm start excellent performance.Rely on unique trapezoidal molybdenum sheet structure, cooperate the ultraviolet starting drive, the warm start performance of described UHP is increased dramatically, the peak value starting resistor can be down to 4kV by 24kV, when realizing energy conservation and consumption reduction effects, greatly reduce designing requirement and the difficulty of projector's relevant control circuit and components and parts, can help projector to reduce on the whole cost, and realize miniaturization.
2, the electrode axiality improves, and provides the space for further shortening pole span.Because the UHP electrode is to be packaged in the spherical lamp housing after being connected by molybdenum sheet, therefore the position of molybdenum sheet and self structure intensity directly affect the electrode axiality.Traditional flat sheet-like structure molybdenum sheet easily is subjected to External Force Acting generation deformation in actual use, and then affects two electrode axialities.The trapezium structure molybdenum sheet is higher than flat sheet-like structure molybdenum sheet in self intensity, and therefore fixed electrode more stably helps to promote axiality, and then guarantees the precision of UHP luminous point.
3, the fault freedom of molybdenum sheet in manufacture process after the reinforcement structural strength is better, reduces difficulty of processing, has promoted rate of finished products, and provides the space for further shortening two interelectrode pole spans.
Therefore, useful technique effect of the present invention has: the peak value starting resistor reduces greatly, is down to 4kV by 24kV; And trapezium structure molybdenum sheet stability is strong, and the electrode axiality of connection is high.
