Preferably, 2 sunny slope of enclosed box body is made of glass or plastic material, and rest part is made of alloy material.
When specifically used, when Ray Of Light is irradiated to 7 large end face of conical fiber, if light is in 7 acceptance angle model of conical fiber
When enclosing interior, light will project in conical fiber 7 by total reflection several times from 7 small end face of conical fiber, last uniform irradiation
Onto the solar battery sheet 4 of bottom；It is unsatisfactory for total reflection condition when light is propagated in conical fiber 7 and will reflect taper
When optical fiber 7, these light can be uniformly reflected on solar battery sheet 4 by reflectance coating 10 to a certain degree, to improve light
The light utilization of fine light cone photovoltaic optical condenser 3.
Theoretically the cone angle of conical fiber 7 is bigger, and focusing ratio is bigger, when single 7 small end area of conical fiber is wireless
When close to 0, focusing ratio theory is infinity.Therefore, it is small to reduce conical fiber 7 for the needs that can be utilized according to solar photoelectric
End area increases light cone focusing ratio.It should be noted that focusing ratio is not the bigger the better, when light is propagated forward in light cone
Every reflection is primary, and the incidence angle of light can all reduce 0.5 cone angle size, and cone angle is bigger, and light propagates every reflection in light cone
Incidence angle reduces bigger, and the acceptance angle of light cone is smaller, and when order of reflection is enough, the incidence angle of light will be less than
The critical angle of total reflection is to cause the loss of energy.It can reduce optical fiber cone when focusing ratio one periodically increases light cone length
Cone angle, the number that the longer light of light cone reflects in light cone also will increase, although when cone angle is smaller each light incidence
The angle that angle reduces is smaller, but the number that light reflects in light cone also accordingly increases, and the acceptance angle of light cone can also become smaller.
Therefore, the balance for acquiring both optical fiber cone cone angle, light cone length according to actual needs acquires the optimal optically focused of poly- cone of rays
Than with optimal acceptance angle, high geometric concentrating ratio and big light acceptance angle can be achieved at the same time, this is refractive type Fresnel condenser
It cannot advantage by comparison with reflexive parabola condenser.
The presentation of 3 large end face evagination of optical fiber cone photovoltaic optical condenser is hemispherical can to increase daylighting area, for single taper
