Abstract
The present utility model relates to a sun illumination angle identification device. The device comprises a hollow ball body (3), vertical light holes (1) are uniformly and centripetally arranged on the hollow ball body, a photosensitive device (2), which is used for generating light-changing current, is arranged on the bottom parts of the light holes, and the stronger the illumination, the stronger the generated current. Light-absorbent materials are painted on the inner walls of the light holes, thus interferences on the photosensitive device can be reduced, and the current generated by the illumination on the photosensitive device is more highlighted. The sun illumination angle identification device can also be used for identifying light sources in other situations, such as, the device can be used for enabling controlled equipment to wave with a control light at night. Compared with other solar energy automatic tracking devices of the prior art, the sun illumination angle identification device is simple in structure, low in cost, convenient in use and accurate in tracking.
Description
Technical field
The utility model relates to field of solar energy utilization, particularly the sunshine tracking adjusting device of solar attachment.
Background technology
The solar energy utilization is the key areas of development in science and technology nowadays, utilizes effect for obtaining better solar energy, and solar energy tracking just becomes one of this field key technology.Existing solar energy tracking device all exists complex structure, the shortcoming of maintenance difficult.
The utility model content
The purpose of the utility model is exactly in order to solve the shortcoming that prior art exists, and a kind of sun light irradiation angle recognition device that provides can identify the angle of solar irradiation, can be used as the foundation that solar facilities is adjusted angle in real time, both with the tracking of doing the sun.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of sun light irradiation angle recognition device comprises a hollow ball, entad offers the loophole that is uniformly distributed with on the hollow ball, is used for the transmission sunray, in the loophole bottom light-sensitive device is set, and is used to produce the light time-dependent current.Light-sensitive device can carry out opto-electronic conversion, and the strong more electric current that produces of illumination is big more.
For obtaining the better recognition effect, apply light absorbent at the loophole inwall, to reduce the interference to light-sensitive device, also outstanding more direct projection is to electric current that light-sensitive device produced.
The utility model also can be used for the identification of other occasion light source, for example, in the curtain of night, lets controlled plant wave along with the control light source.
The beneficial effect of the utility model is: compare other automatic solar energy tracking device of the prior art, the utlity model has simple in structure, with low cost, easy to use, follow the tracks of advantage accurately.
Description of drawings:
Fig. 1 is a sun light irradiation angle recognition device structure principle chart.
Embodiment:
A kind of sun light irradiation angle recognition device as shown in Figure 1, that the utility model provides comprises a hollow ball 3; Entad offer on the hollow ball and be uniformly distributed with vertical light transmission hole 1; Be used for the transmission sunray, light-sensitive device 2 be set, be used to produce the light time-dependent current in the loophole bottom.Light-sensitive device can carry out opto-electronic conversion, and the strong more electric current that produces of illumination is big more.
Loophole on spheroid have point to the centre of sphere, more deeply, thin, vertical, even attribute such as gather.After spheroid was fixing, each loophole angle was also confirmed immediately.Carve under the solar irradiation at a time; Because the different and constraint of loophole angle in all loopholes, has only Ray Of Light a can vertically arrive the light-sensitive device of loophole bottom; So the light that this hole sees through is maximum; The electric current that its corresponding light-sensitive device produces is also maximum, and the angle of this loophole is the lighting angle of the sun just, thereby can adjust the foundation of solar facilities angle in view of the above.
Said light-sensitive device can select for use photodiode as light-sensitive device, like model: XYC-PT5X850AC, and overall dimension: 2～5mm, dark current:＜0.1uA, light current: 500～1000uA.This device can produce the electric current that changes with light intensity, electric current excursion 0.1～500uA.
For obtaining the better recognition effect, smear light absorbent at the loophole inwall, to reduce the interference to light-sensitive device, also outstanding more direct projection is to electric current that light-sensitive device produced.
Claims (2)
1. sun light irradiation angle recognition device is characterized in that: comprise a hollow ball (3), offer one group of loophole (1) that entad is uniformly distributed with on the hollow ball, each loophole bottom is provided with light-sensitive device (2).
2. sun light irradiation angle recognition device according to claim 1 is characterized in that: the inboard light absorbent that applies of loophole.
