Description

Solar energy hierarchical architectural lighting lighting device
Technical field
The utility model belongs to application of solar, is specifically related to solar energy hierarchical architectural lighting lighting device.
Technical background
The comprehensive utilization of the energy is subject to the common concern of society, is the most important thing of the permanent development of society.Solar energy, as a kind of regenerative resource and clean environment firendly, becomes the nowadays substitute of many traditional energies.Utilizing sunshine to throw light on is a kind of novel lighting device that international community extensively adopts.For energy-conservation and improve indoor illumination environment, make full use of sunshine resource, domestic and international many researchers are studied this, propose many daylighting methods for designing of utilizing sunshine.For example: utilize the reflection of speculum, total reflection, light pipe or the optical fiber leaded light of prism group, sunshine is directly guided to the indoor place that needs illumination; Also can indirectly utilize the infra-red radiation of sunshine, produce heat generating for illumination; Or utilize photoelectric effect, by sunshine directly become electric energy for illumination etc.Clearly, sunshine being directly used in to daylighting illumination is one of the most economic and efficient mode.
3D solid composite parabolic type concentrator is that a kind of low light gathering according to rim ray principle design is than non-imaging concentrator, for minute surface composite parabolic type concentrator, there is larger reception half-angle, can accept wider incident light, can fixedly mount with architectural exterior-protecting construction, do not need to arrange tracking system simultaneously.Through experimental study, in the time that solar irradiation is mapped to entity composite parabolic type concentrator, part sunshine will escape out from concentrator side surface bottom, and the now also seldom sees that correlative study utilizes this part light.Along with the change gradually of angle of incidence of light is large, the sunshine of escaping out also can increase gradually simultaneously, and this phenomenon will be more obvious.In current application, be mostly the light of collecting to carry out classification utilization, with light-conducting system, the light collected imported to each place needing and throw light on, and seldom consider the utilization of the sunshine that lighting equipment escapes out.
Utility model content
In order to solve the problem of utilizing of above-mentioned escape sunshine, the utility model is using escape sunshine out as one-level utilization, and the sunshine that optically focused is collected utilizes as the second level, and a kind of solar energy hierarchical architectural lighting lighting device is provided.
Concrete technical solution is as follows:
Solar energy hierarchical architectural lighting lighting device comprises concentrator, described concentrator is the non-imaging concentrator of 3D solid, the 3D solid compound parabolic concentrator that each concentrator is the three-dimensional center symmetry that formed around central shaft rotating 360 degrees by parabola, its end face and bottom surface are plane, the parabola that the outer cylinder at middle part is transparent non-plated film; Rearrange concentrator array by several concentrators, the serve as reasons plane of end face composition of several concentrators of the end face of concentrator array, the bottom surface of the each concentrator in concentrator array is connecting respectively light-conductive optic fibre, and the light-conductive optic fibre of several concentrators forms respectively a branch of above fibre bundle; When use, solar light irradiation is at the end face of concentrator array, at the end face generation refraction action of each concentrator, part sunshine is penetrated and is formed first order illumination by the paraboloidal bottom of concentrator, and the fibre bundle transmission that another part sunshine is focused to light-conductive optic fibre composition by total reflection effect forms second level illumination.
Described concentrator material is high light transmissive material, and refractive index is greater than 1.
The bottom surface of the each concentrator in concentrator array is connecting a cylindrical axial one end, and the cylindrical axial other end is connecting light-conductive optic fibre; The material of described cylindrical material and concentrator is identical.
The utility model utilizes without the 3D solid composite parabolic type concentrator of plated film collecting in the process of sunshine, and the light of escaping out utilizes as the first order architectural lighting of sunshine; In the second level of light utilizes, adopt optical fiber binding technology to direct light into each indoor simultaneously, again realize the multilayer utilization of light.The utilization rate of light is significantly improved.Because device has expanded the acceptance angle of concentrator, only need fixed installation, easy to use, can combine with application background such as building grade well.Meanwhile, due to total reflection effect, optical property is improved; Adopt the parabola of concentrator without coating structure, further improved the economic benefit of system.
