Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module aging devices, and particularly relates to a UV light aging device. Background Technology

[0002] In the photovoltaic field, during product manufacturing and research, it is necessary to conduct ultraviolet aging tests on various materials and devices used both outdoors and indoors, which require the use of UV light aging devices.

[0003] In existing technologies, commonly used light sources for UV photoaging devices include low-pressure mercury lamps (UVA, UVB) and metal halide lamps. However, existing technologies have problems such as significant differences in matching degree between the 280-400nm wavelength band and the standard solar spectrum AM1.5 or AM1.0. Due to the low photoelectric conversion efficiency and wide spectrum of the light source, the power consumption of the equipment is generally high. At the same time, the light source of existing devices illuminates the sample from top to bottom. In order to achieve irradiation uniformity, a large optical path must be set, which will result in problems such as large equipment size. The light source of metal halide lamps has a short lifespan, which affects the overall service life of the aging device. Summary of the Invention

[0004] The present invention aims to solve the above problems and provide a UV photoaging device with optimized size and long service life.

[0005] The UV photoaging device of this utility model includes a housing, a support frame, and a light source array;

[0006] Both the support frame and the light source array are housed within the aforementioned box.

[0007] The support frame includes several units; the support frame is used to place the sample to be tested, and multiple samples to be tested can be placed simultaneously by setting multiple support frames.

[0008] The support frame is set on both sides of the aforementioned light source array; the sample to be tested is placed on the support frame and set on both sides of the light source array, which can maximize the utilization of light energy and improve the UV irradiation efficiency.

[0009] Furthermore, in the UV photoaging device of this invention, the light source array consists of UV fluorescent lamps and UV-band LED lamps. The UV-band LED lamps include three types of LEDs with wavelengths of 360-370nm, 380-390nm, and 390-410nm. The combination of multiple light sources improves photoelectric conversion efficiency; the flexible allocation of multiple light sources allows for better UV spectrum matching; and the long lifespan of both fluorescent lamps and LED lamps further extends the overall lifespan of the photoaging device.

[0010] Furthermore, in the UV photoaging device of this invention, the light source array is arranged perpendicular to the bottom of the aforementioned housing; the support frame is also arranged perpendicular to the bottom of the aforementioned housing. This vertical arrangement minimizes the footprint of the device and facilitates light source maintenance.

[0011] Furthermore, in the UV photoaging device of this invention, the light source array is mounted on a water-cooled support. When the ambient temperature is high, the lifespan of the light source will decrease. By mounting the light source array on a water-cooled support for water cooling, the temperature of the light source array can be effectively reduced, thus extending the lifespan of the light source.

[0012] Furthermore, in the UV photoaging device of this invention, a reflector is provided between the support frame and the light source array; by providing a reflector, more UV light can be irradiated onto the sample to be tested, thereby improving the light energy utilization rate.

[0013] Furthermore, in the UV photoaging device of this invention, the chamber is provided with a heat insulation layer; by providing a heat insulation layer, the temperature inside the chamber can be better controlled, providing a stable test environment temperature, thereby improving the test accuracy.

[0014] Furthermore, in the UV photoaging device of this invention, the UV fluorescent lamp and LED lamp are each connected to a separate adjustable power supply. By providing independent adjustable power supplies for different light sources, a certain type of light source can be switched on or off individually, or its output power can be changed, resulting in better spectral matching of the UV light and timely adjustment when deviations occur.

[0015] Furthermore, in the UV photoaging device of this invention, the support frame is provided with an adjustment part for adjusting the size of the support frame; by adjusting the adjustment part, it can adapt to test samples of different sizes, thereby improving the applicability of the aging device.

[0016] Furthermore, in the UV photoaging device of this invention, the housing is provided with a double door or opening at a position corresponding to the support frame. The double door or opening facilitates the placement and removal of the sample to be tested, thereby improving efficiency.

[0017] The UV photoaging device described in this invention employs a light source array. By vertically arranging the light source array within the chamber, the internal layout is optimized, resulting in a smaller device size. Furthermore, placing the sample to be tested on both sides of the light source array maximizes the utilization rate of the light energy. The entire UV photoaging device has a simple structure, is easy to operate, and is suitable for widespread application. Attached Figure Description

[0023] The UV photoaging device of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0024] This embodiment discloses a UV photoaging device, such as... Figure 1 As shown, the UV photoaging device described in this embodiment consists of a housing 1, a light source array 6, and two support frames 3. Both the light source array 6 and the support frames 3 are housed within the housing 1, with the two support frames 3 located on either side of the light source array 6. The support frames 3 are used to hold the sample 5 to be tested. The light source array 6 is vertically positioned at the bottom of the housing 1, and the support frames 3 are also vertically positioned. The sample 5 to be tested is vertically fixed to both sides of the light source array 6 via the support frames 3. An insulation layer 2 is provided on the housing 1; in this embodiment, it is formed by filling a steel plate with rock wool.

[0025] A reflector 4 is provided between the light source array 6 and the support frame 3. In practical applications, the reflector 4 can be placed on any side of the light source array 6 between the support frame 3, either vertically or horizontally, depending on the specific circumstances. In this embodiment, reflectors 4 are provided on all four surfaces between the light source array 6 and the support frame 3, forming a ring. In this embodiment, the reflector 4 is made of mirrored aluminum plate, but polytetrafluoroethylene plate can also be used in specific applications. The reflector 4 allows more UV light to irradiate the sample 5 under test, thereby improving the light energy utilization rate of the device.

[0026] In the embodiments disclosed herein, such as Figure 2As shown, the light source array 6 includes UV fluorescent lamps 7 and UV-band LEDs. The UV-band LEDs include 365nm LED beads 10, 385nm LED beads 11, and 400nm LED beads 12, all three types of LEDs arranged on an LED strip 8. In this embodiment, the LED strip 8 is formed on an aluminum substrate using PCB technology. The LED strip 8 and the UV fluorescent lamps 7 are regularly arranged to form the light source array 6, achieving uniform irradiation for each light source. In specific applications, composite LED beads containing multiple peak wavelengths can also be used as needed.

[0027] In this embodiment, three types of LED lamps are each connected to an adjustable constant current power supply. The power output of the constant current power supply can be adjusted via its control terminal, thereby regulating the light power of the corresponding LED lamp. The UV fluorescent lamp 7 is equipped with an adjustable electronic ballast. Adjusting the output of the electronic ballast via its control terminal allows for the regulation of the light power of the corresponding UV fluorescent lamp 7. By providing separate adjustable power supplies, individual switching control of a particular type of light source can be implemented, or its output power can be changed, thereby improving the spectral matching of UV light and enabling timely adjustment in case of deviations.

[0028] In this embodiment, the light source array 6 is mounted on a water-cooled support 9. Water cooling effectively reduces the temperature of the light source array 6, extending its lifespan. Simultaneously, water cooling does not affect the temperature of the sample 5 on the support frame 3, thereby improving the testing accuracy of the photoaging device described herein. Figure 1 , Figure 4 As shown in this embodiment, the LED light strip 8 is mounted on the water-cooled bracket 9, and the UV fluorescent lamp 7 is mounted near the water-cooled bracket 9. The water-cooled bracket 9 is a hollow aluminum profile, and cooling water is passed inside to effectively dissipate heat from the LED light strip 8, preventing the LED light strip 8 and the UV fluorescent lamp 7 from overheating when the temperature inside the housing 1 is high.

[0029] In the embodiments disclosed herein, such as Figure 3 As shown, the support frame 3 consists of two horizontal bars and two vertical bars. The upper horizontal bar is set as an adjustment part 13, and its two ends can slide on the two vertical bars. When it slides to the position of the dotted box in the figure, the size of the entire support frame 3 can be adjusted to adapt to various specifications of test samples 5.

[0030] In practical applications, a double door or opening can be set on the housing 1 at a position corresponding to the support frame 3, so that the sample 5 to be tested can be put in or taken out through the double door or opening, thereby improving the operating efficiency of the aging device described in this utility model.
