Description

Optical sensor holder for solar position tracking {CdS SENSOR HOLDER}

The present invention is to install an optical sensor used for tracking the position of the sunlight in the holder, more specifically, using a CdS (cadmium sulfide cell) the weather of strong light intensity emitted from the sunlight, that is, The present invention relates to a technology capable of easily performing detailed detection of sunlight even in an illuminance range in which a large amount of light is irradiated.

In recent years, the world's oil prices have been soaring due to the limited dependence on electricity, gas, and oil resources. On the other hand, mankind has been seriously contaminated with environmental pollution due to the increase in greenhouse gases caused by the use of petroleum energy. have.

Accordingly, attention has been focused on the development of alternative energy using nature such as solar power, wind power, and tidal power that can be used indefinitely in an eco-friendly manner without generating environmental pollution. Among them, it is especially used for homes and industries using solar heat. The development of a device for producing a heat source for hot water or heating is being actively progressed.

1 is a view showing a state in which a conventional optical sensor for tracking the position of sunlight installed in the holder.

A conventional optical sensor for tracking the position of sunlight, that is, a holder 10 in which a CdS element is installed, is referred to as patent application 10-2007-0088774 (filed Sep. 3, 2007). The partition 13 is installed on the center of the body having a columnar shape to form two first grooves 14 and a second groove 14-1, and the formed first grooves 14 and the second grooves are formed. The first light sensor 15 and the second light sensor 15-1 provided with the CdS in the recess 14-1 are installed in pairs, respectively, and the solar light 16 is disposed on the upper portion of the body 11. A filter 12 made of a transparent or translucent material, in which light emitted from the light is collected, is configured.

Here, various types of optical sensors, such as CdS (cadmium sulfide cell) and phototransistor, are used. Among them, CdS may be referred to as a capacitance of a resistor (or "resistance value") depending on the amount of light to be irradiated. This change is made to the sensing operation.

For example, most of the CdS has a resistance value of 5Ω (ohm) to 250KΩ (kiloohm), which operates by sensing a dose of light, and has a high resistance value in a dark state and irradiates the CdS surface. The brighter the light, the lower the internal resistance value of the so-called light-on type is used.

In other words, when the light emitted from the sunlight 16 is irradiated to the surface of the CdS, the resistance value of the CdS decreases, and at this time, the current flowing through the CdS increases to eventually light-on the light. An operation is performed, and a detection signal converted from the optical signal into the current signal is generated.

On the other hand, the first optical sensor 15 and the second optical sensor 15-1 installed in a pair by detecting the sunlight in the east direction and the west direction or the south direction and the north direction according to the installation direction A solar plate (not shown) for producing solar power is connected to a separate driving device (not shown), so that the tracking operation is performed toward the sunlight 16.

However, the conventional technology configured as described above is a clear weather having strong light intensity emitted from the sunlight 16, for example, the first light installed between the partitions 13 in an illuminance of 10,000 lux or more. When sunlight is collected through the filter 12 by the sensor 15 and the second light sensor 15-1, the influence of the shadow caused by the partition wall 13 is very weak, and thus the first light sensor 15 and the first light sensor 15 and the second light sensor 15-1 are collected. Since the resistance value with the two light sensors 15-1 is in a state where there is almost no difference (for example, 0? (Ohms)), this causes a problem that correct position detection of the sunlight 16 cannot be achieved. Done.

Therefore, a solar panel (not shown) for producing solar power or a heat collecting plate (not shown) for producing solar heat cannot track the solar light 16, resulting in a reduction in thermal energy. Inexpensive installations have resulted in many problems that can't produce solar power or solar heat properly.

In addition, the present invention has another object to make the solar tracking or solar heat collecting plate to produce solar power through the detailed sensing operation of the sunlight to facilitate the solar tracking.

Means for solving the problems of the present invention as described above is characterized in that a pair of holder (Holder) is installed, each pair of the first optical sensor and the second optical sensor is configured.

In addition, the holder is integrally fixed so that one side portions of the body are opposed to each other based on the partition wall, and light emitted from the sunlight is adjacent to the partition wall portion at one side of the body. In addition to having a light inlet to be characterized in that the first light guideway formed in the longitudinal direction is configured.

In addition, the first light guide and the refraction and the second light guide is connected to the light inlet from the light inlet is refracted and has a space to be distributed to the detection unit of the first light sensor and the second light sensor through the light outlet Characterized in that the second groove is configured.
