Description
[technical field]
The present invention relates to a kind of road-light light-source operating room annular seal space barometric control unit, be specifically related to a kind of LED road-light light-source operating room annular seal space external barometric control unit.
The invention belongs to technical field of lighting fixtures, its principle relates to the automatic control technology field.
[background technology]
The LED illumination is emerging green illumination high-tech industry, and the led light source product has environmental protection, energy-efficient characteristics, has obtained various circles of society and has extensively paid attention to.Be different from other artificial electric light source, obtain the work of led light source device stability and high efficiency ground, need LED road-light light-source operating room to be in enough good sealing state:, should reach IP65 or higher according to the equipment protection grade.
Conventional road lamp is used this class device hardly, therefore also seldom relates to the notion of this sealing applications.The appearance of LED lighting source has proposed the brand-new technology requirement to LED street lamp operate as normal, comprising the seal request considerably beyond conventional road lamp: require the LED street lamp to reach the exclusion seal grade of IP65 at least.This requirement is that for example: in the coastal area, sea wind carries the high concentration salt fog, will cause heavy corrosion in case enter electrical equipment according to the reasonable request of LED road-light light-source characteristics and environment characteristics proposition; In some industrial developed regions, comprise densely populated city, filling the air toxic and harmfuls such as having corrosive vehicle exhaust, boiler smoke and chemical emission in the air, sky also can land sometimes and have corrosive acid rain.All this kind, safe and efficient application all brings direct or indirect threat for the LED street lamp.
Allow the LED street lamp can long-term stability the ground operate as normal, just be necessary for LED street lamp operate as normal and create condition of work standard, safety.The sealing grade that regulation LED street lamp must reach is exactly one of these minimum measures.
Why does the LED street lamp need sealing? because the LED street lamp belongs to the electronic electric equipment that illumination functions is provided.For needs safe in utilization, also keep the works fine state to need for equipment, must implement excellent waterproof, protection against the tide, dustproof, anti-preventative technical measures such as go mouldy to equipment, conscientiously pick up from the fault source, major accidents such as electric leakage, short circuit, equipment corrosion are stopped in strictness, the phenomenon that cause condensing in lampshade the inside fog even the globule can not occur changing because of the lamp housing internal and external temperature takes place, and also must stop dust accretions shut out the light, reduces road illumination in transparent lamp shade function deterioration situation simultaneously and occur.
Artificial electric light source is used for street lighting, owing to produce huge heat during its work, the light source works indoor temperature is very high, causes the light source works chamber interior when gases are heated, they expand that air pressure raises, order about the light source works indoor gas flow to outdoor, until reaching dynamic equilibrium.When closing street lamp, light source device is no longer worked, and heating stops, and the light source indoor temperature descends gradually, and indoor gas volume systolic pressure gradually reduces, and extraneous air flows into the indoor dynamic equilibrium that reaches indoor and outdoor air pressure again.Along with the periodically opening and closing of street lamp every day, the road-light light-source chamber is as sharing a common fate, and the gas in the operating room periodically exchanges with the external world.This just gas exchange, changed the indoor subenvironment state of light source works gradually: it is indoor that the extraneous gas that carries pollutants such as dust enters into the static relatively light source works of narrow space, air-flow, the pollutant that gravitational field and electrostatic adsorption cause inflow gas to carry lands gradually and is attached to transparent lamp shade and light source part surface, even infiltrate through device interior, simultaneously also bring steam inevitably, the necessary condition of the fog and globule cohesion is provided.Along with day alternates with night if things go on like this, road-light light-source work indoor gas constantly exchanges with the external world: what spill out is air through the relative purification of precipitation and absorption back, what come in is the gas that road carries a large amount of fouling products and outflow from lamp housing.In the course of time accumulate over a long period, just cause the often visible street lamp of the new line phenomenon that the light is dusky of people: a large amount of dirt depositions in the lampshade, as installed thick and heavy ' curtain ' additional to transparent lamp shade, except long-term use causes the factor that the electric lighting device luminous efficiency decays naturally, because of ' curtain ' effect causes the dimly lit phenomenon of street lamp very general, the reason of its technical elements just is not difficult to have explained.
Implementing enough high-grade sealing protection technical scheme, is the essential measure of stopping above-mentioned bad phenomenon.The LED street lamp that lacks light source works chamber annular seal space barometric control unit, might cause light source works chamber body gas inside pressure following temperature change to take place than great fluctuation process and near or exceed its withstand voltage limit, cause parts such as LED streetlamp housing housing and transparent lamp shade, be subjected to the threat of this fluctuation at aspects such as structure, materials, even can cause LED street lamp product general safety performance deterioration and reliability to reduce.Even the phenomenon of the failure that may cause equipment to break do not occur, reduce initial sealing effectiveness even the seal failure of product, the hidden danger of this possibility is serious the existence.In order to obtain excellent sealing effect, can thoroughly avoid the excessive harmful effect of gas pressure fluctuation in the LED road-light light-source operating room cavity again, a kind of LED road-light light-source of the present invention operating room annular seal space external barometric control unit just arises at the historic moment.
The related annular seal space regulator of external regulator pressure bladder is installed in outside the LED road-light light-source operating room annular seal space, its pressure regulation pressure bladder is communicated with LED road-light light-source sealing intracavity gas, and constitutes hermetically sealed gas and interconnect the space with LED road-light light-source seal chamber, sealing connecting pipe.The regulator pressure bladder is a balloon: rubber balloon, metal forming balloon, PVC balloon, batts balloon, bellows, ball inner bag, metal foil seal container, rubber seal container, PVC polymeric seal container.Be in the external pressure bladder of relative free space by use, special gas circulation duct and LED road-light light-source operating room annular seal space by good seal are interconnected, so the external pressure bladder does not take any space of annular seal space, LED street lamp operating room.The regulator pressure bladder is installed in the independent casing outside the LED road-light light-source operating room annular seal space, in order to make the moulded unification of LED street lamp attractive in appearance, the design of lamp holder not only comprises the LED lighting source, also can be with the external regulator, even all unify to be arranged in power supply driver in the scope of the total moulding of LED road lamp cap: one Room, ' one Room ' or one Room, ' two Room ', the regulator pressure bladder be installed in the shared casing of LED road lamp power supply driver in, perhaps be reserved with the pressure bladder operating room of LED road-light light-source annular seal space external regulator in the LED road lamp power supply driver casing.Rationally arrange, close fit, compact conformation, handsome in appearance.
LED road-light light-source operating room annular seal space is idealized as rigid structure: its shape and the constancy of volume when temperature and air pressure change.When being subjected to thermal pressure, intracavity gas raises, just can in external regulator pressure bladder, find a way out by closed conduit, because this air bag ' external ' is in the atmospheric environment of space free, capacity and volume freely stretch, its air pressure inside is almost consistent with outside atmosphere, flows to the other end so the hyperbar of pipeline one end must order about led light source sealing intracavity gas; Conversely, descend when LED road-light light-source room temperature reduces air pressure, gas just refluxes immediately in the external regulator pressure bladder, reaches dynamic equilibrium once more.Because LED road-light light-source working chamber and external regulator pressure bladder connect into as a whole confined space by closed conduit, isolate fully with ambient atmosphere, therefore at the LED street lamp in effective lifetime, although gas flows many times, but gas gross and composition keep constant fully in light source annular seal space and the pressure regulation pressure bladder, certainly just can not be subjected to any influence of environmental contaminants, also just can not be because gas causes the LED street lamp to take place unusual even breaks down.
According to the data analysis that " pneumatic engineering manual " provides, depress at a normal atmosphere, set with 20 ℃ volume of air as standard unit 1, when variations in temperature, its Volume Changes is substantially near linear rule, and is as shown in the table:
| Temperature ℃ | -20 | -10 | 0 | 10 | 20 | 30 | 40 | 50 | 60 |
| Relative volume | 0.8635 | 0.8977 | 0.9317 | 0.9662 | 1 | 1.0345 | 1.0686 | 1.1028 | 1.1370 |
As can be known from the above table: if our hypothesis is a reference data with 20 ℃, the routine work temperature of LED street lamp, comprise that environment temperature is set in-20 ℃～60 ℃ the temperature range, then the positive negative value of relative variation of its light source works chamber interior volume of air is no more than 15%.Consider the relation between the perfect gas pressure, volume, temperatures that classical theory disclosed such as gay lussacs law, Boyle's law, The Ideal-Gas Equation pV=nRT, and consider certain engineering allowance, for LED street lamp configuration the present invention ' LED road-light light-source annular seal space external regulator ' be scientific and reasonable fully, also be necessary fully.
The external mode of LED street lamp annular seal space external regulator of the present invention both can be independent external, and was so relatively more simple, only needed to make the casing of ' comfortable ' to pressure bladder; Also can with LED street lamp external power supply driver ' Room of living together ', a shell is dual-purpose, is convenient to production and processing and installation.Experience shows: if the LED street lamp adopts the built-in power supply driver, because the lamp housing temperature drift, cause that the power failure rate significantly rises, LED street lamp overall reliability index declines to a great extent.Give LED road lamp power supply driver in view of needs and ward off the new home in addition, should reserve the working space of external regulator pressure bladder when considering the power supply driver casing, it is few to plan that like this totle drilling cost increases, but effect is fine, kills two birds with one stone.
