Description

Technical Field

[0001] The present invention relates to the technical field of indoor light source testing systems, and in particular to an indoor light source testing system and method. Background Art

[0002] In recent years, most microelectronic devices are used in indoor environments. The spectrum of indoor light sources is different from that of sunlight. The existing organic optoelectronic material system is not suitable for indoor organic photovoltaic devices. Organic optoelectronic devices are thin and easy to absorb light. They can more effectively absorb indoor light and convert light energy into electrical energy in indoor light environments. Obtaining these parameters is very important for the development and research of new organic materials and the characterization of material properties. To meet the requirements of devices suitable for indoor light, the key is that the spectrum of indoor light sources is mainly distributed in 400-700nm, and the spectrum of the device's response to light must be the same as the spectrum generated by the indoor light source to reduce the energy loss caused by the narrow energy band of photons.

[0003] Existing indoor light source testing systems generally use organic photoelectric material systems to operate indoor organic photovoltaic devices. However, the spectrum of indoor light sources is different from that of sunlight. Within an illumination range of 200mm x 200mm, its non-uniformity cannot be reduced to less than 5%.

[0004] Aiming at the problem that the existing indoor light source test system cannot achieve a non-uniformity of less than 5% in the 200mm x 200mm irradiation range, the indoor light source test system can simulate different indoor light environments by providing a large area of ​​LED light sources to meet diversified test needs, thereby improving test efficiency. By accurately controlling the brightness and color temperature of each LED lamp bead, the uniform output of the light source is achieved to ensure the accuracy of the test results. At the same time, the lamp bead array module adopts an exclusive design of LED lamp bead array, covering the 350-1000nm spectrum range, ensuring the uniformity and color reproduction of the light source. The precise arrangement of the lamp beads is achieved through a precise arrangement mechanism to optimize the uniformity of the light source, so that the non-uniformity of the light source within the range of 200mm x 200mm is less than 3%, and the non-uniformity of the light source within the range of 300mm x 300mm is within 5%. Users can choose one of the three color temperatures of 3000K, 4000K, and 6000K to simulate the indoor light environment in different time periods. Users can flexibly adjust the color temperature according to test requirements to evaluate the performance of the device at different color temperatures. Summary of the invention

[0005] In order to overcome the problem that the existing indoor light source test system generally uses an organic photoelectric material system to operate indoor organic photovoltaic devices, and the spectrum of the indoor light source itself is different from that of sunlight, its non-uniformity cannot be reduced to less than 5% within the 200mm x 200mm illumination range.

[0109] S122: At each color temperature, use a spectrum analyzer to measure the spectral distribution of the light source to ensure accurate color temperature adjustment.

[0110] 3. Data analysis: record and compare spectral data at different color temperatures.

[0113] Conclusion: The accuracy of color temperature adjustment is verified by measuring the spectral distribution of the light source. The color coordinates (x, y) and the main wavelength are the key parameters for evaluating the color temperature of the light source.
