Description
Technical field
The present invention relates to a kind of high-intensity discharge lamp, relate in particular to the ceramic gold-halogen lamp of a kind of long-life, tunable optical, double-arc tube.
Background technology
For saving electric power, light regulating technology is usually adopted in current road lighting, before midnight traffic more for a long time, the lamp full-load operation, the rare car of the spacious people in the road time after midnight is few, it is safer to drive a vehicle, therefore reduce lamp power with reduction illumination, thereby reach energy-saving effect, can make lamp be operated in abnormal condition simultaneously but such light modulation not only increases cost, not only light efficiency and colour rendering index significantly reduce, and influence the lamp life-span; Another kind of used scheme is to adopt two independently lamps, and before midnight, two lamps were lighted simultaneously, only lighted wherein one time after midnight, and this also makes the illumination investment increase.
The present invention is provided with two the high-intensity discharge lamp electric arc tubes that can distinguish independent operation or running simultaneously to replace the work of two individual light in a lamp, under the optimum Working that does not change lamp, obtain dimming effect, with respect to two independently for the lamp, illuminator is simplified while cost easy to use and is reduced relatively, the problem that the present invention that Here it is need solve.
Summary of the invention
The object of the present invention is to provide a kind of high light efficiency, tunable optical, life-span long and can with the illumination high-intensity discharge lamp of existing road illuminating lamp Interface Matching.
For achieving the above object, the present invention has taked following technical scheme:
Tunable optical, long-life high-intensity discharge lamp comprise transparent outer cover (1), contact conductor (3), (4) and (5) of sealing.Described contact conductor (3), (4) are by outside stem stem (7) lead-out lights made from the shell same material.Another contact conductor (5) then is piercing in transparent outer cover (1) through bead (2); In transparent outer cover (1), cross-over connection has first electric arc tube (12a) and second electric arc tube (12b) between the first electrode side rod, the second electrode side rod and the third electrode side rod, constitutes double-arc tube ceramic metal halide lamp.
Too high and cause the electric arc tube thermal expansion excessive and cracked for fear of temperature rise in the running, so buffer substrate tablet (13a), (13b) are set between electric arc tube and electrode side rod.
For making double-arc tube high-intensity discharge lamp of the present invention can directly insert the screw socket light fixture that current existing road illumination is adopted, above-described high-intensity discharge lamp has adopted and the identical screw socket of conventional lamp.Because two electric arc tubes in the lamp of the present invention need three outputs could realize the requirement that two electric arc tubes work alone, so the 3rd of lamp the electrode outlet line adopts the lamp top of passing through commonly used in the electron tube to draw through the bead sealing among the present invention, and the one metal crown top of burner is set as this electrode leads to client on the lamp top.
Above-described high-intensity discharge lamp electric arc tube can or be long pole span electric arc tube for short pole span electric arc tube; For long pole span electric arc tube, then need be adopted as the conductive strips device that reduces starting resistor and establish.
Above-described conductive strips device is made of conducting ring and conducting film connecting band; Described conduction hoop is located at the root of the sleeve at bulb of electric arc tube two ends; Described conducting film connecting band is electrically connected the conducting ring on the sleeve at bulb of electric arc tube two ends.Described conducting ring and conducting film connecting band are made by aquadag.Described conductive strips device also can be made of the filament that curls on electric arc tube.
The high-intensity discharge lamp that this kind has two electric arc tubes can adapt to the needs of different occasions, by two independently the external impressed current adjustment that two electric arc tubes are realized is collaborative, separately or the work of rotating.Two electric arc tubes in the lamp can be that same size also can be a different size, can dispose according to bright requirement design electric arc tube like this, thus the dimming function that realization requires; Certainly, also can be only the another electric arc tube be made standby pipes with electric arc tube wherein.Or make the work of rotating of two electric arc tubes, thereby doubled in the life-span of lamp.In sum, the two-tube high-intensity discharge lamp with this structure can be used in numerous occasions with specific (special) requirements, and brings into play its advantage.
Technique effect of the present invention is: this high-intensity discharge lamp cooperates external circuit, can realize light modulation, increases the service life, function such as thermal starting, can be widely used in having the occasion of specific (special) requirements.
