DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a photovoltaic radiation acceleration test apparatus according to the present invention will be described in detail with reference to the accompanying drawings. In the present specification, the same or similar reference numerals are given to different embodiments in the same or similar configurations. As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise.

FIG. 1 is a conceptual diagram showing an apparatus 100 for testing solar photocopy according to an embodiment of the present invention. FIG. 2 is a conceptual view showing an enlarged view of a portion A shown in FIG. 1, And a test plate (150).

Referring to FIGS. 1 to 3, the solar radiation acceleration test apparatus 100 includes a body 110, a partition 120, a light source 130, a rod 140, and a test plate 150.

The body 110 has an upper space 110a and a lower space 110b, which are spaces that can be accommodated therein, as shown in FIG. The body 110 may include a frame and a panel made of aluminum. 1 shows the inside of the solar radiation acceleration test apparatus 100. Although not shown in the figure, the body 110 may have a door unit (not shown) that can be opened and closed to check an internal space . In addition, an observation window (not shown) for observing the inner space of the body part 110 may be installed in the door part without opening the door part.

The partition 120 is disposed between the upper space 110a and the lower space 110b so as to divide the inside of the body 110 into an upper space 110a and a lower space 110b, Hole 120a. The upper space 110a and the lower space 120 are separated based on the partition 120 as shown in FIG.

The light source unit 130 is disposed in the upper space 110a and is configured to generate light into the lower space 110b through a through hole 120a provided in the partition 120. [

2, the light source unit 130 may include a lamp 131 and a reflector 132. [

The lamp 131 is configured to generate light for simulating the sunlight. The lamp 131 may be made of, for example, a metal halide lamp.

The reflector 132 reflects light generated from the lamp 131 so as to focus the light generated from the lamp 131 to the test plate 150 disposed in the lower space 110b, As shown in Fig. Accordingly, the intensity of radiation by sunlight can be increased by concentrating the light with the test plate 150. In addition, the reflector 132 may be configured such that its relative position with respect to the lamp 131 is adjustable. For example, the reflector cap 132 can adjust the position of the lens cap 131 and the focus of the reflector cap 132 so that the position of the light reflector 132 can be adjusted all the way around, Can also be made possible.

2, the lamp 131 and the reflector 132 may be fixed on the lamp fixing panel 134 and the lamp fixing panel 134 may be disposed on the upper space 110a And is mounted on the position adjusting rail 137 which horizontally crosses the inside of the position adjusting rail 137 so that the position can be adjusted along the position adjusting rail 137.

The light source unit 130 includes a lamp cooling fan 137 that generates a wind toward the lamp 131 to prevent the lamp 131 from overheating.

The rod 140 is disposed in the lower space 110b and extends from the partition 120 to the lower space 110b. In addition, the number and length of the rods 140 can be designed differently from those shown in accordance with the conditions required in the test.

The test plate 150 is formed to be irradiated with light generated from the light source unit 130 and fixed at a predetermined position on the rod 140 or movable along the rod 140. The test plate 150 may be made of a wood plywood in consideration of thermal deformation and thermal conductivity. Further, a test sample (a test subject) or an instrument 151a or the like may be placed on the test plate 150. [ For example, the meter 151a may be a solar system for measuring the amount of solar radiation energy, and the solar system may be connected to an indicator to confirm whether solar radiation energy corresponding to the test condition is output.

Also, the test plate 150 can be arranged such that a certain amount of radiation is applied in a state in which the distance from the light source unit 130 is fixed, and thereby the actinic ray effect test by sunlight can be effectively performed.

Further, in the mode in which the test plate 150 is moved along the rod 140, it is possible to perform a thermal effect test that can simulate the actual sunshine amount. For this test, the solar radiation acceleration test apparatus 100 may further include a control unit (not shown). The control unit may be configured to control the moving speed of the test plate 150 in a mode in which the test plate 150 moves along the rod 140.

On the other hand, the solar radiation acceleration test apparatus 100 may further include an optical filter 160.

The optical filter 160 is disposed on the boundary between the upper space 110a and the lower space 110b of the body 110 and transmits the light generated in the light source unit 130 to the lower space 110b, This branch is formed to convert into a spectrum.

For example, when the metal halide lamp is directly irradiated with the lamp 131, the light beams reaching the sample placed on the test plate 150 are separated from the sunlight by a small amount Other states of light can be reached. This may be an inconsistent condition for the purpose of the test, so that the optical filter 160 can be used to convert the spectrum of the lamp 131 to be similar to sunlight. Further, the optical filter 160 can be formed so that the radiant energy of the lamp 131 is close to the radiant energy spectrum of the sunlight by adjusting the transmittance performance by the wavelength band, and is placed close to the lamp 131 to receive hot light And may be formed of pyrex glass which is one of the heat-resistant optical glasses.

According to the present invention described above, the body part 110 is partitioned into the upper space 110a and the lower space 110b by the partition 120, and light is generated from the upper space 110a to the lower space 110b And a test plate 150 disposed in the lower space 110b and being irradiated with light generated from the light source unit 130 and being movable along the rod 140. The light source unit 130 may include a light source unit 130, The amount of radiation due to the light generated in the light source unit 130 can be greatly increased by making the distance between the test plate 150 and the test plate 150 close to each other and the test is performed by setting various conditions through the movement or fixed structure of the test plate 150 . For example, according to an embodiment of the present invention, a radiation amount of 4,480 or more, corresponding to four times the natural radiation amount of 1,120, can be realized. Further, the radiant intensity applied by the ramp 131 by the inverse square law is inversely proportional to the square of the distance. Since the distance between the test plate 150 and the lamp 131 is adjustable, it is possible to confirm how the characteristic change of the sample varies with the drainage of sunlight.

In addition, the present invention can perform a test for observing the influence of heat accompanied by the phenomenon of actual sunshine, and it is possible to fix the distance between the test plate 150 and the lamp 131 and to measure the influence of ultraviolet rays, visible rays, All of the tests that observe the effects of the actinic radiation are possible.

In addition, among the various fields that need to consider the influence of the sunlight, it is possible to test virtually any sample which is used in a part which is considered to be severely affected, As the strength changes, the results can be compared. This leads to a relationship expressing that the acceleration system is established and can effectively implement the acceleration test model.

In addition, the present invention makes it possible to construct a database by measuring changes in lifespan or property of a material used in various fields such as defense and weapons systems, civil water, industrial, and architectural structures due to exposure to sunlight radiation. This can contribute to reliable system design and construction.

Meanwhile, since the temperature inside the body 110 may affect the test result, the solar radiation acceleration test apparatus 100 may further include a temperature holding unit 170 to solve the above problem.

The temperature holding portion 170 is configured to maintain the temperature of the lower space 110b of the body portion 110 under predetermined conditions. For example, the temperature holding unit 170 may include a heater 171, a fan 172, and heat insulating members 173a and 173b.

The heater 171 is mounted on one surface of the body 110 of the lower space 110b and can generate heat to heat the internal space of the body 110. [ The heater 171 may be a film heater formed in the form of a film, and may be mounted on at least one surface of the inner wall of the body 110. In addition, the temperature control method of the heater 171 can be performed by an on / off method.

Meanwhile, the heater 171 may be disposed in a plurality of different regions in the lower space 110b, as shown in FIG. The temperature holding unit 170 may be configured to independently adjust the temperature of the heater 171 disposed in different regions. Accordingly, the photovoltaic radiation acceleration testing apparatus 100 of the present invention can set the temperature condition of the lower space 110b to be more various.

The fan 172 is disposed at the periphery on the test plate 150 and may be configured to generate wind in the upper region of the test plate 150. Accordingly, the solar radiation acceleration test apparatus 100 can solve the temperature rise problem due to heating due to excessive radiation of the lamp 131. Further, in combination with the heater 171, a temperature holding mechanism in which heating and cooling are combined can be realized. For example, when the internal temperature of the body 110 reaches a predetermined level through the heater 171, the power supply is interrupted to stop the heating, and the fan 172 is operated and put on the test plate 150 The ambient air temperature of the specimen can be kept constant. Thereafter, when the temperature inside the body 110 is lower than a predetermined level, power is supplied to the heater 171 to raise the temperature inside the body 110 to a predetermined level. In addition, the fan 172 may include a power supply unit 172a that is supplied with power necessary for driving.

The heat insulating members 173a and 173b are disposed so as to cover at least one surface of the inside of the body 110 to prevent temperature loss inside the body 110. [ The heat insulating members 173a and 173b may be composed of a first heat insulating member 173a disposed in the upper space 110a and a second heat insulating member 173b disposed in the lower space 110b. In addition, a silicone or rubber packing may be further provided to seal the inside of the body 110 to prevent temperature loss.

 According to the above-described structure of the present invention, the temperature holding unit 170 is provided to maintain the temperature of the lower space 110b of the body 110 at predetermined conditions, Or a cooling device may be mixed to maintain the temperature condition of the lower space 110b of the body 110 more stably.

However, the scope of the present invention is not limited to the configuration and method of the embodiments described above, and all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments. In addition, the present invention can be applied to all equivalents of inventions, such as inventions that can be modified, added, deleted, or replaced at the level of those skilled in the art, It belongs to the scope is self-evident.
