Complementary application of electrodeless lamp and LED According to the principle of illumination, the electrodeless lamp is a gas discharge fluorescent lamp. It is based on the traditional energy-saving fluorescent lamp to further improve the technology. It replaces the electrode discharge with electromagnetic coupling. On the basis of inheriting the traditional mature technology, the performance is higher. And fully break the technical bottleneck that traditional energy-saving fluorescent lamps are only stuck in low-power lighting. The product has been improved by technology, and its performance advantages are mainly reflected in high luminous efficiency, long life, high color rendering, low heat generation, and no stroboscopic. LED is a solid-state light-emitting technology. This technology has been used in image display and signal indication fields for more than 30 years. Its entry into people's lives as a general-purpose lighting began in the 1990s, with relatively short development and application times. Due to the high efficiency and energy saving of LEDs, the current government and researchers have invested a lot of money and manpower in research and development, and strive to apply this product technology in the field of general lighting. Throughout the current development of the technology, despite the rapid development of research and development (especially low-power LED), there are still many technical difficulties in the application of high-power lighting, which is far from being able to achieve the expectations of people. From the latest data release, the laboratory LED light efficiency can reach 180lm/w, theoretically it has great potential for development, and the market prospect is immeasurable. However, in the high-power research and development, the problems reflected in light color, heat dissipation, light decay, and physical fitness are still a flaw. These reasons are inseparable from the technical development of LED. The difference between it and the electrodeless lamp is that the electrodeless lamp is breakthrough and improved in the traditional and mature technology, and the LED is expanded in the image display and signal indication. The technology lacks a mature technology base and application practice foundation like the Promise, so there are certain difficulties in solving the current problems faced by LED. But its technological breakthrough in low-power lighting is worthy of recognition. However, whether it is at high power or low power, the problem of light color is still a big problem. From the high-power white LED spectrum analysis tested by Hangzhou Zheda Tri-color Instrument Co., Ltd., the blue-ray radiation with a wavelength of about 440 nm is prominent in the spectral radiation distribution (bottom left), and the blue-light radiation of this wavelength is generated by the human endometrium. Chemical hazards are obvious and fail to create a comfortable, healthy lighting environment for people. Since Edison invented incandescent lamps, artificial light sources have gone through more than 100 years of history, but they are still short-lived compared to the human evolutionary history of hundreds of millions of years. Human beings themselves are not able to adapt to such a variable optical radiation environment, especially the global attention caused by laser and semiconductor light sources. When the characteristics of the illumination source are different from the characteristics of natural light and natural light, human physiology, psychology, and health will have certain effects. At present, LED products for daily use are mainly in the near ultraviolet, visible and near infrared bands. Therefore, the optical radiation hazard of LED products mainly considers the near-ultraviolet radiation damage of the eye, the photochemical damage of the retinal blue light and the thermal damage of the radiation. In contrast, the spectral radiation distribution wavelength of the electrodeless lamp is more prominent at 544 nm (bottom right). This wavelength belongs to the most sensitive band of the human eye to light radiation, and is more suitable for human eye sensitivity. It is a healthier green light source. . From the light color analysis of the two illuminating technologies, the light color performance of the electrodeless light source in the field of general illumination is superior to that of the LED. The shortcoming is that in the long run, although the luminous efficiency of the electrodeless lamp can reach 90lm/w, the upward lifting space is limited by the luminescent material and the principle of illuminating, and there is no sign of breakthrough.
With the global warming, the development of a low-carbon economy has become an international consensus and a new economic growth model for developed countries in the future. The low-carbon economy is therefore expected to be not only an environmentally friendly means of the traditional industrial economy, but also a new impetus for the global economy to emerge from the "financial tsunami." As a low-carbon economic forward, it is the rapidly developing energy-saving lighting industry. Especially the green light source represented by LED semiconductor lighting is highly praised by governments and is known as a driver for a low-carbon economy. In the process of the domestic LED lighting industry rushing into the rush, in the case that its technology is not fully mature, in recent years, the introduction of magnetic induction induction lamp products has also shown a development trend that complements the application of LEDs. So, are these products different in technology and application? Are there any complementarities? Where are their advantages and disadvantages? This paper analyzes the complementarity of LEDs and electrodeless lamps in technology and application.
Technical differentiation analysis of electrodeless lamps and LEDs
Infinity lamps and LEDs are the same as green light, because they are highly efficient, long-life and so on. Although there are many similarities in performance, there are essential differences in technology and application.
