Description
Technical field
The present invention relates to a kind of lighting, specifically a kind of deformation type street lamp breathing equipment.
Background technology
At present, the illumination of through street, town road generally adopts traditional street lamp to form main flow lighting system, and light source is high-pressure mercury lamp (HPS) and metal halide lamp (MH).This lighting system technology maturation is reliable, but there is problem---the dirt deposition phenomenon of glass shell inside of a long-standing problem in it, namely after running after a while, a large amount of dirt can be assembled at the lamp shade glass inner bottom part of road lamp cap, block the light that light source irradiates downwards, cause street lighting efficiency greatly to reduce.
The essence of glass shell dirt phenomenon is caused to be the cell breath that light source produces.Cell breath process is as follows:
Initial equilibrium conditions: after street lamp is installed, when light source is unignited, light fixture inner and outer air pressure is identical, the gas motion that inside and outside lamp holder, on interface, nothing is macroscopical.
(1) exhalation process: after light source is lighted, lamp holder internal temperature raises rapidly, and cause lamp holder internal gas pressure to increase, on inside and outside interface, mineralization pressure is poor.When this pressure differential reaches enough high, at the weakness of interface, as the places such as poorly sealed or aging seam, screw find an exit, the pressure-air in lamp holder will be extruded lamp holder, to reduce the pressure differential inside and outside lamp holder, thus reaches new balance.In this course, define the macroscopic motion of gas from inside to outside, i.e. " inner gas of breathing out ".
(2) suction process: after light source extinguishes, lamp holder internal temperature can progressively be reduced to identical with outside air temperature.In temperature-fall period, the pressure of lamp holder inside also decreases, and formed " negative pressure " relative to outside, on inside and outside interface, mineralization pressure is poor.When this pressure differential reaches enough high, extraneous gas can pour in from the weakness of inside and outside interface under suction function, forms the gas macroscopic motion of ecto-entad, i.e. " suction extraneous gas ".
Be not difficult to find out, suction process is exhalation process " inverse process " in principle.
It is worthy of note, suction gas is different from the gas componant of exhalation.In exhalation process, the gas of " exhalation " is from inside to outside the air of manufactory assembly shop, normally cleaner; In suction process, in the gas of ecto-entad " suction ", then contain the pollutant such as dust, soot, tail gas elaioleucite be suspended in a large number in the air of road overhead.After these pollutants enter lamp holder inside, can be adsorbed under gravity on the lamp shade glass of lamp holder inner bottom part, the residual and gathering of pollutant forms the schmutzband of macroscopic view.
(3) cyclic process: after light source is lighted again, this respiratory will be showed again.Go round and begin again, cause schmutzband more long-pending thicker, blocked the downward light of street lamp and led to.
Current solution is: the gas crossover passage 1, inside and outside isolated lamp holder, and the method for employing strengthens the sealing of lamp holder, such as, use better, more durable sealing ring.The problem of this method is, even if use better, more durable sealing ring, also can be aging because of HTHP, lose sealing function the most at last, form respiration channel.
2, filter the inside and outside gas exchanged, adopt filter type, filter breathing gas with activated carbon etc.The problem of this method is, activated carbon filtration after certain useful life reduces, and need change in time.
The total problem of said method needs to need to change equipment in lamp holder in time in street lamp use procedure.Under the poor actual conditions of China's road lamp management, owing to too relying on artificial replacing, in fact, all long-pending full dirt bottom long-term operating street lamp.Therefore, really solving the cell breath problem of street lamp technically, is the effective way improving street lighting efficiency.
Summary of the invention

The principle that the present invention solves cell breath problem is the high pressure reducing to be formed in lamp holder because lamp holder internal temperature raises, and inside and outside interface is not reached and produces breathing necessary " pressure differential ".
Described a kind of street lamp Projecting Lamp deformation breathing equipment, its course of work is: after light source is lighted, inner chamber heats and produces air pressure change, chamber pressure is caused to increase gradually, cavity is inside and outside forms malleation, and now hot gas is drained into deformable body by scavenge duct by inner chamber, deformable body is expanded and becomes large, thus the air pressure in inner chamber is reduced, reach new balance; Deformable body becomes the normal pressure be delivered in shell greatly and is discharged to lamp holder outside by UNICOM's conduit, makes also to keep normal pressure in shell; After light source extinguishes, inner chamber turns cold, and causes chamber pressure to diminish gradually, and cavity is inside and outside forms negative pressure, and now inner chamber absorbs the gas in deformable body by scavenge duct, and deformable body is reduced, thus makes the air pressure in inner chamber become large, recovers Yuanping City's weighing apparatus; After deformable body reduces, the negative pressure be delivered in shell is supplemented by UNICOM's conduit by the gas of lamp holder outside, recovers normal pressure in shell.
In this process, the unpurified gas of suction will not enter inner chamber, but enter and presetly in shell deposit in the space of dirt, like this, can not form dirt bottom street lamp glass lens.
