Abstract
The utility model relates to a photoelectric type sun tracker which comprises a light tight rigid shell body and a plurality of luminous diodes. The rigid shell body is provided with an open end and is sealed by non-light tight materials, the luminous diodes are arranged in the rigid shell body in parallel, illuminated faces face to the open end of the rigid shell body, and a photospot center line of the luminous diodes and a location surface of the non-light tight materials form a certain included angle. The luminous diodes are connected in a parallel or photocurrent arithmetic additive way, and output differential voltage signals after receiving optical lines. A drive circuit outputs normal sun orientation signals of the TTL PWL after processing the differential voltage signals, the normal TTL PWL signals can directly drive a direct current motor module, and thereby drives the motor to carry out corresponding motion. Two photoelectric type sun trackers form 90 DEG mutually and are arranged vertical to a solar cell sailboard, and the solar altitude and orientation angle can be tracked.
Description
Affiliated technical field
The utility model relates to a kind of photo-electric sun tracker, belongs to field of solar energy.
Background technology
Concentrating photovoltaic power generation is a main trend of field of solar energy development, and in order to realize the accurate tracking to the sun, the research and development of sun tracker become one of key.Several technology of present disclosed sun position sensor mainly contain: adopt the photoelectric sensor of solar battery pas detector element, its seizure sun angle scope is big but detectivity and precision are low, the cost height; The four-quadrant photoelectric sensor of being furnished with respective optical system, its detectivity is high but effectively to survey the sun angle scope little, complex structure.
Summary of the invention
The purpose of this utility model provides a kind of photo-electric sun tracker.This photo-electric sun tracker is followed the trail of accurately, power consumption is little, Installation and Debugging convenient, integrated level is high.
The utility model comprises a lighttight stiff case and several light emitting diodes, stiff case has an openend, and seal by light transmissive material, the light-emitting diodes tube side-by-side is listed in stiff case inside, its sensitive surface is towards the openend of stiff case, and the optically focused center line of light emitting diode becomes certain included angle with plane, light transmissive material place.When sunlight light shone on the PN junction of light emitting diode, PN junction produced the photoproduction electromotive force, and the size of this electromotive force is not only relevant with intensity of illumination, and is simultaneously also closely related with the incidence angle of light.Light emitting diode connects with the arithmetic addition form of arranged side by side or photoelectric current.By comparing the electromotive force that each light emitting diode or each light emitting diode group are produced, again this signal is amplified differential voltage signal of output, drive circuit is handled the solar azimuth signal of the Transistor-Transistor Logic level of back outputting standard to the differential voltage signal, the Transistor-Transistor Logic level signal of standard can directly drive the direct current generator module, thereby drive motors carries out corresponding action.Two these photo-electric sun trackers are in 90 °, and with vertical placement the in solar cell windsurfing plane, can realize sun altitude and azimuthal tracking.
For the utility model can be become apparent, hereinafter special with specific embodiment, and cooperate appended graphicly, elaborate.

Among the figure, 1. rigid body shell, 2. light transmissive material, 3. light emitting diode, 4. circuit board.
The specific embodiment
Specific embodiment of the utility model comprises a lighttight stiff case 1 and several light emitting diodes 3, stiff case 1 has an openend, and by light transmissive material 2 sealings, light emitting diode 3 also is arranged in stiff case 1 inside, its sensitive surface is towards the openend of stiff case 1, and the optically focused center line of light emitting diode 3 becomes 90 °, 60 ° angle with plane, light transmissive material 2 place.When sunlight light shone on the PN junction of light emitting diode 3, PN junction produced the photoproduction electromotive force, and the size of this electromotive force is not only relevant with intensity of illumination, and is simultaneously also closely related with the incidence angle of light.Light emitting diode 3 connects with the arithmetic addition form of arranged side by side or photoelectric current.By comparing the electromotive force that each light emitting diode or each light emitting diode group are produced, again this signal is amplified differential voltage signal of output, drive circuit is handled the solar azimuth signal of the Transistor-Transistor Logic level of back outputting standard to the differential voltage signal, the Transistor-Transistor Logic level signal of standard can directly drive the direct current generator module, thereby drive motors carries out corresponding action.
Two photo-electric sun trackers are in 90 °, and with vertical placement the in solar cell windsurfing plane, can realize sun altitude and azimuthal tracking.
Though the utility model discloses as above with preferred embodiment, be not in order to limiting this creation, anyly be familiar with this skill person, various changes and the retouching done in the spirit and scope that do not break away from this creation also belong to the scope of this creation.Therefore, the protection domain of this creation attached claim person of defining after looking is as the criterion.
