Description
Technical field
The present invention is relevant a kind ofly to transfer to indoor conducting system with outdoor sunlight, mainly is a kind ofly to be fixed on the building, sunlight directly is conducted into indoor sunlight collecting that throws light on and light conducting system.
Background of invention
At present, some are the indoor illumination of daylighting directly, mainly is to utilize light fixture.In the use, both consume electric power had unsafe hidden danger again simultaneously, and this point is for some job shops, market or be positioned at underground arsenal or the like and more seem particularly important.Rely on the lighting of electric energy in addition, can only launch the light of single wavelength, the people is experienced less than the sensation that is washed in the sunshine, main cause is that the wave-length coverage of sunshine is very wide, and the people is felt comfortably cool.
For the indoor or factory building of sunlight being introduced directly daylighting etc. is located, make the people feel the illumination of true nature, people invent out a kind of tubular type skylight, as United States Patent (USP) 5502935, this patent disclosure a kind of femerell device, on the roof, be provided with a skylight, a light transmission device is installed on ceiling, between the two by a pipeline transmission light.Its operation principle is that light enters pipeline by the roof light transmission device, and is indoor with reflection back importing for several times in pipeline.In this technical scheme, the light transmission device on roof is that the skylight by a dome structure constitutes.But, the skylight of this structure had only when the positive period of the day from 11 a.m. to 1 p.m just can make sunlight enter in the pipeline effectively, and when the light deflection, the incidence angle of sunlight is very low, the light that enters in the pipeline is less on the one hand, too little because enter in the pipeline reflection angle of light on the other hand, thus light can be in pipeline with low-angle carry out after repeatedly the reflection could inlet chamber in, the intensity of light has been weakened in reflection repeatedly soon.And cross when low when the angle of light, then can not enter pipeline and realize the conduction of sunlight.
For overcoming above-mentioned defective, this patent applicant proposes another again and improves technical scheme, this technical scheme by U.S. Patent number be 5,655,339, denomination of invention is disclosed for " the tubular type skylight with new-type dome ".The improvements of this patent are, are prism in the some of the outer surface of the north side of dome, and this prism surface constitutes POLO (Porro) total reflection prism by a plurality of vertical slots of arranging along the dome great-circle direction, and this prism is arranged at the north side of dome.Its operation principle is, when sunshine during with lower incident direction irradiation dome, light sees through side domed-face by north and is radiated on POLO (Porro) total reflection prism of north side, and the total reflection light by this prism is reflected back toward in the dome and enters in the light-conductive pipeline.This technical scheme has overcome the defective of above-mentioned former prior art, and the angular range of the sunlight that conducted has been enlarged, and has therefore increased the illumination intensity and the time in skylight effectively.
But, carry out total reflection by total reflection shuttle mirror again and return in the dome because this light that is radiated on the dome wants saturating this southern side dome could arrive the reflection shuttle of north side, and is radiated on the total reflection prism.Like this, when light passes the wall in dome southern side and enters in the dome, require the material of dome that higher light transmittance is arranged, and reduce reflection of light as far as possible, make light enter dome as much as possible.And the shuttle groove that passes the north side when the light that enter dome carries out reflex time, requires the dome material to have bigger refractive index again, thereby enlarges the angular range of its total reflection.Fresnel formula by optics can learn that both are conflicting, and this refractive index and transmissivity promptly are determined after light transmissive material is determined.In fact, as light transmittance that this United States Patent (USP) adopted up to 80%～90% light transmissive material, pass the wall in dome southern side when light, when shining on the reflection rib of north side, most light can see through this and have the wall of the north side of rib groove, have only few part can realize reflecting and entering once more in the dome, its reflection efficiency is low.
Owing to have only the total reflection that when angle is positioned within the critical angle of total reflection, could realize light, and in fact, after the fixed in shape of the rib groove of dome north side, rotation and circumsolar revolution along with the earth, the incident angle of light is all changing all the time, so be difficult to make that this shuttle groove shape can be corresponding to the incident angle of being satisfied with all light, and realize its total reflection.
Therefore, desire realizes reflecting effect preferably, must design the shape of different grooves corresponding to the incident angle of each light, and this almost is impossible realize in practical engineering design, and the difficulty of processing and manufacturing is considerably big.Therefore, vertical slot in this patent adopts the project organization of two-stage, and the two-stage vertical slot staggers mutually, makes every effort to reach the requirement that it can satisfy the angle of various incident ray.Obviously, with regard to the present material and the restriction of working ability, the implementation result of this patented technology is the requirement that does not reach the designer.For these reasons, even this patent can be reflected in the pipeline by the light that angle is lower, but its efficient of gathering sunlight is equally very low.
