Embodiment Construction

[0015] Below in conjunction with accompanying drawing, the present invention will be further described through embodiment.

[0016] see figure 1 According to the invention, the solar graded building daylighting lighting device includes a concentrator, and the concentrator is a three-dimensional solid non-imaging concentrator. Each concentrator is a three-dimensional centrosymmetric three-dimensional solid compound parabolic concentrator formed by a parabola rotating 360 degrees around the central axis. Its top surface 4 and bottom surface are planes, and the outer cylindrical surface in the middle is a transparent non-coated paraboloid 5 . see figure 2 A concentrator array is formed by arranging several concentrators, and the top surface 4 of the concentrator array is a plane composed of the top surfaces of several concentrators. Depend on image 3 with Figure 4 It can be seen that the bottom surface of each light collector in the light collector array is respectively c...

Abstract

The invention relates to a solar grading building lighting illumination device. The solar grading building lighting illumination device comprises condensers, wherein each condenser is a three-dimensional solid composite parabolic condenser which is formed by 360-degree rotation of a parabola around the central axis and is in three-dimensional central symmetry, the top surface and the bottom surface of the condenser are planes, and the outer column surface of the middle part of the condenser is a transparent non-film-plated parabola; a condenser array consists of a plurality of condensers; the top surface of the condenser array is a plane formed by the top surfaces of the plurality of condensers; the bottom surfaces of all the condensers in the condenser array are respectively connected with light-guiding optical fiber which forms more than one optical fiber bundles; sunlight irradiates on the top surface of the condenser array, and is refracted on the top surface of each condenser, one part of the sunlight is ejected by the lower parts of the parabolas of the condensers to form first-grade illumination and the other part of the sunlight is transmitted by the optical fiber bundles to form second-grade illumination. The solar grading illumination device has the advantages that the light utilization rate is obviously increased; the solar grading illumination device is convenient in installation and use, and can be well combined with the application backgrounds such as buildings.

Description

technical field [0001] The invention belongs to the technical field of solar energy application, and in particular relates to a solar energy graded building daylighting and lighting device. technical background [0002] The comprehensive utilization of energy has received widespread attention in today's society and is the top priority for the long-term development of society. Solar energy, as a renewable energy and clean and environmentally friendly, has become a substitute for many traditional energy sources today. Utilizing sunlight for lighting is a new type of lighting device widely used in the international community. In order to save energy, improve the indoor lighting environment, and make full use of sunlight resources, many scientific researchers at home and abroad have studied this and proposed many lighting design methods that use sunlight. For example: use the reflection of the mirror, the total reflection of the prism group, the light guide of the light pipe o...
