All of the above are OLED lights. Although LED lights are already an environmentally friendly light fixture, OLED lights are more environmentally friendly than LED lights. OLEDs are organic electroluminescent diodes, mainly emerging technologies in which organic semiconductor materials emit light under the action of an electric field. With the improvement of people's living standards, there is a higher demand for the quality of daily life. The development of OLED lighting technology has played an important role in improving the quality of people's lives.
According to the data, global sales of OLED lighting will reach 150 million US dollars in 2015, which is expected to grow at an average annual growth rate of 75%, and will reach 2.4 billion US dollars in 2020. By 2023, the total output value of OLED lighting is expected to soar to a maximum of $6.7 billion. Subsequently, it is expected to fall back to $5.5 billion by 2025.
Analysis of basic structure and working principle of OLED
1.1 OLED section structure analysis
With the advancement of the organic light-emitting diode lighting market, the related technologies of organic light-emitting diodes have also progressed to varying degrees. The OLED is one of the important technological developments, and its structure is relatively simple. The luminescent layer panel is sandwiched between the upper and lower substrates. This is the hole transport layer and the luminescent layer and the electron transport layer. After the illuminating layer is powered on, it can emit light, and according to the red, green and blue equipment can produce different colors, so that the OLED can fully reflect the unique luminescent characteristics. In the process of illuminating, the voltage requirement is relatively low, but the effect of illumination is the same as the others. At the same time, the organic light-emitting diode is also provided in the reaction fast, light weight and low cost.
1.2 Analysis of working principle of OLED lighting technology
In the process of working, OLED is mainly realized by a sandwich structure. First, a layer of organic material is sandwiched between two electrodes, and then the cathode and the anode and other parts are placed on the substrate. The structure is mainly glass or plastic. Then, after a low DC voltage is applied across the electrodes, the charged particles can illuminate when they are combined in this organic film.
Development Status and Technical Analysis of OLED Lighting
2.1 Analysis of the development status of OLED lighting
From the development of the actual situation, the development of OLED lighting has made great progress. OLED light source has been a leaps and bounds in the lighting industry and has been favored by the industry. At present, many lighting products have increased their investment in this field, and OLED light sources have been vigorously promoted as high-end products.
As an emerging way of lighting, in order to achieve longer life development in the future, it is necessary to further improve OLED technology, and to make breakthroughs in the efficiency of lighting and the life and display quality of use. At present, the efficiency of using phosphorescent materials as OLED materials has exceeded that of incandescent lamps, but there is still much room for improvement compared with actual expectations. In the application of phosphorescent materials, the efficiency factor of OLED is 25 percent. The increase to nearly 100%, the low light emission rate is an important factor affecting the luminous efficiency of this lighting technology at this stage.
In addition, in terms of the lifetime of OLED lighting, there are significant differences in the life requirements of screen devices for illumination sources and portable handheld devices. The life of current OLEDs is sufficient for portable device display screens, but for lighting, it is necessary to double or five times on the existing basis. At the same time, the differential aging of the luminescent material has an important influence on the white light quality, which can indirectly affect the life of the OLED. As the technology continues to improve, the stability of white light quality and the efficiency of luminescence will be further improved.
2.2 Specific discussion of OLED lighting technology
Because OLED lighting technology is different in form, it also has outstanding performance in practical applications. These are mainly reflected in their transparency and lightness and softness, self-illumination and many other aspects. In terms of transparent geometry, the main thing is that the OLED is a transparent medium when it is not illuminated, and it can become a whole source of light after turning on the light at night. The unique transparency of OLEDs creates a new experience in both display and lighting applications.
In addition, OLED lighting technology is also reflected in the form of bendable arc, and the unique softness characteristics of OLED lighting also open up a broad prospect for its practical application in the future. There is also an important manifestation of the characteristics of high color rendering. OLED lighting technology has more than 95% of color rendering, which is more suitable for use in photography and art fields, and then coupled with cold light. The traits, which have a wider application in the lighting of surgery.
The application of OLED lighting technology in the market is mainly in two important fields. One is the display market, and the other is the lighting market. The actual performance of OLED lighting technology still has its drawbacks, making it less in the development of lighting. display. In the field of lighting, it is mainly in advertising strips as well as in contour lighting and department stores, freezer and many other fields. High efficiency, long life and low cost are the key to the industrialization of this lighting technology. The efficiency mainly reflects the ability to convert electrical energy into light energy, and the life span reflects practicality. At present, white OLED mainly has two mainstream device structures, that is, a stacked structure and a single light-emitting unit. In these two kinds of single light-emitting units, the required voltage for white light operation is relatively low, so it is easier to obtain higher. Luminous efficiency.
Conclusion
All in all, in the development stage of the global energy shortage and the need to protect the environment for sustainable development, the issue of energy conservation is a matter of national importance. OLED lighting technology can exert certain effects on energy conservation, and continuously improve and improve this technology to maximize the efficiency of actual operation. Due to the limited space of this article, we cannot further study it. I hope this effort can be used as a reference. And the role, to be better as a theory in this field to further improve and guide the actual development.
