Technical field
The portion within it of the present invention relates to is not subjected to form a kind of lighting apparatus of condensate and some biological forms of generation.
Especially, the present invention's installation light source site of lighting apparatus in lighting apparatus inside of recommending to produce has and can prevent to form condensate and prevent to breed some a kind of inert environments as mould, liver moss, bacterium or insect and so on vegetalitas or animality biological species on perisporium.
Background technology
As everybody knows, lighting apparatus have the structure that is formed for the light resource installing section position and perisporium that above-mentioned installation position is made with glass or other light transmissive materials by one side at least round situation under because thermal unbalance and on perisporium, form condensate continually between external environment condition and the device interior.
This phenomenon is that this just causes usually said humidity owing to always have the actual conditions of certain percentile water to cause in the suspension in atmospheric air.Each connect light source and when producing heat, the air temperature rise of lighting apparatus the inside.Yet the perisporium of equipment contact outside air keeps lower temperature.As a kind of result who produces heat in the lighting apparatus the inside, contained in equipment the inside have in the air just evaporation and just be condensate on the perisporium when it enters when contacting with the perisporium with lower temperature of the water in the suspension itself, and generation is referred to as the phenomenon of smog usually.
Especially, the condensate deposition that may appear on the lighting apparatus the inside reflection perisporium causes its albedo to weaken, and the smog on the transparent perisporium of lighting apparatus causes in the loss aspect itself light transmittance.
Everybody also knows most of lighting apparatus, especially those are used for the lighting apparatus of external purposes, another problem be to need the plant of oxygen and/or breeding of animal character biological species in equipment the inside.Such problem obviously is that this environment is because the characteristic of its illumination, humidity and temperature is favourable to breeding of some biological species usually because the environment of lighting apparatus the inside causes.
If by making the sealing gland of equipment own can overcome the problem that animality and/or vegetalitas biological species are bred in the equipment the inside, thereby though then prevent that through introduce the air be not infected with at device interior these biological species from then entering the lighting apparatus the inside by these biological species, with this solution and do not mean that the problem that has solved the formation condensate.
Further, consider that water vapor pressure has along with temperature raises and the very rapid nonlinear change process that increases, containing to a certain degree, the lighting apparatus sealing gland of humidity air can cause undesirable pressure increment in the device the inside.Though in the surface texture of enough heat exchanges is arranged, can ignore this phenomenon, but for the lighting apparatus with general volume and some little surfaces (for example as embossing and so on) is considerable, wherein is exposed to some little surfaces in the ventilating air and has limited greatly by conduction and convection current and come heat dispersing.Therefore change on the structure (so must calculate specific dimensions) not only but also on the face of weld and especially be used for causing sizable stress on the binding agent of sealing device at the pressure of lighting apparatus the inside at lighting apparatus.
With for preventing to breed contemplated opposite of some biological species in lighting apparatus the inside, these defectives should need air to circulate between equipment inside and outside.A kind of air that can the formation temperature balance between the within and without of lighting apparatus itself is quite coordinated to circulate and also can be avoided forming in the lighting apparatus the inside problem of condensate.
Summary of the invention
The present invention recommends can overcome simultaneously and breed some problems of vegetalitas and/or the interlock of animality biological species in equipment, a kind of solution of avoiding forming condensate on the surface of equipment and significantly limiting the over pressure problem.
So main purpose of the present invention is to provide a kind of lighting apparatus of the installation position that structurally forms at least one light source, the perisporium that above-mentioned installation position is made with glass or another kind of light transmissive material by one side at least round, wherein got rid of more above-described problems.
Further purpose of the present invention is to provide a kind of lighting apparatus that keeps its efficient not need frequent maintenance to regulate with illumination rated power at any time.
Reach these according to purpose of the present invention by the lighting apparatus that the feature with claim 1 defined is provided.
In additional subsequently claims, point out some further features of lighting apparatus of the present invention.
According to following illustrative and nonrestrictive description, consult the lighting apparatus schematic diagram that expression is equipped with the printing opacity peripheral wall structure that the light source volume limit to be installed of enclosing, will seem more obvious according to some feature and advantage of lighting apparatus of the present invention.
Consult accompanying drawing, form lighting devices with the light source 2 that is positioned at lighting apparatus 1 pedestal, form the structure of lighting apparatus 1 by three perisporiums 3 and one side upper perimeter wall 4, more above-mentioned perisporiums are all made with light transmissive material.The lighting device 1 that its side perisporium 3 is housed is placed on the pedestal 5, the reflecting surface 6 that contains the folded light beam function is arranged, make light beam be considered to upwards dispersion on the direction of coordinating most with other method in the lighting apparatus the inside.
Side perisporium 3, top perisporium 4 and pedestal 5 are determined an inner space 7.
Obviously, because the cause of the distance of printing opacity side perisporium 3 and light source 2 positions makes lighting apparatus significantly be subjected to forming the negative effect of condensate on side perisporium 3.Especially, the condensate that forms on reflecting surface 6 causes the minimizing aspect its reflected energy, and the smog of side perisporium 3 light transmitting surfaces causes the loss aspect its light transmittance, therefore causes the dilution of the illumination energy of lighting apparatus 1.
It is particularly advantageous forming and keep a kind of inert atmosphere in lighting apparatus 1 the inside under these circumstances.
In order to reach such purpose, the present invention recommends to be full of with anhydrous inert gas 7 inner space 7 of lighting device 1.Further, with the border of the inner space 7 on the contact surface between the different parts of sealing cement bar 8 sealings in lighting apparatus 1 structure, to prevent air and/or water (be in a liquid state or as the steam) inner space 7 of access arrangement subsequently.
The inert nature that is full of the gas of lighting device 1 inner space prevents to breed some vegetalitas and/or animality biological species in the lighting apparatus the inside.Further, the possibility that does not exist water also to avoid on perisporium, forming condensate and formed over pressure.
In order to be full of in lighting apparatus 1 the inside and can to recover anhydrous inert gas, lighting apparatus 1 is equipped with by recovering at least one valve element of gas stream.Except that need portion within it prevent biological species breed with condensate in the situation of gas-tight seal lighting apparatus 1 fully such temporary expedient also be necessary.
Some that can preferably use gas according to the present invention is nitrogen and argon gas.Nitrogen means most economical solution (can obtain nitrogen from air with fractionation process) easily again, and is specially adapted to prevent to need the breeding of biological species of oxygen.Though argon gas is more expensive, argon gas need not only to prevent from the breeding of biological species of oxygen equally, and guarantees fully to interact with the binding agent that is used to seal.
This lighting apparatus, purpose of the present invention, have for having some problems to be solved that a kind of advantage of effective workaround is provided and solving the advantage that all are bred with biological species in lighting apparatus 1, condensate forms the problem relevant with over pressure in addition in its surface simultaneously.
Further, according to lighting apparatus 1 of the present invention,, therefore keep its illumination rated power at any time owing to need fragmentary simple maintenance to regulate.
