I. Overview MK series electrodeless lamps are developed and manufactured by Mianyang Mianke Electronic Technology Co., Ltd. Now they have been used in batches in many different occasions. From the measured data, the use of MK series electrodeless lamps is very effective and fully meets the design requirements. MK series electrodeless lamp has different technical characteristics from other electrodeless lamps, and it has taken an important step towards completely solving the bottleneck that restricts the development of electrodeless lamps. Mianke Electronic Technology Co., Ltd. currently develops 10W to 200W series electrodeless lamps, 10W to 35W are integrated lamps, and 35W or more lamps are split lamps.
Second, what is the electrodeless lamp gasless discharge lamp lighting technology is an interdisciplinary emerging technology, it involves the power electronics technology, gas discharge and light theory, plasma theory, electromagnetic field theory and many other areas, is a set of common progress Only possible scientific and technological achievements. The electric energy required for the work of the electrodeless lamp is coupled to the bulb through electromagnetic induction, ionizing the mixed vapor of the low-pressure mercury and the inert gas in the electrodeless bulb into a plasma. When the excited mercury atoms return to the ground state, the wavelength of the radiation is emitted. Ultraviolet radiation of 253.7nm excites the three-color phosphors on the inner wall of the bulb to convert the ultraviolet light (invisible light) into visible light. The electrodeless gas discharge lamp has advantages that many other existing light sources do not have, such as more energy-saving, long service life, good color rendering, instant start, high power factor, etc. Therefore, research on electrodeless lighting systems has practical application value and potential. The great commercial value. The design of electrodeless lamps has been proposed for almost 100 years, but only in the past more than 20 years has made great progress. There is a controversy about whether the electrodeless lamp is developing towards high frequency or low frequency. The difference between the low frequency lamp and the high frequency lamp is that the operating frequency is 230KHz and 2650KHz. We firmly believe that the high frequency is the development direction of the electrodeless lamp.
III. Eight Misunderstandings of Low-frequency Electrodeless Lamps 1. The International Standard issued by the International Radio Interference Committee (CISPR) [CISPR15] (the fourth edition of 1992) clearly states that there are two electromagnetic induction lamps. The operating frequency can be used: (I), 13.65MHz. Everlight Electrodeless fluorescent lamps of Panasonic Corporation in Japan work in this band. II, 2.2 ~ 3MHz band. It falls between medium-wave and short-wave and is rarely used for radio broadcasts and receptions. This band is selected by Philips' QL induction fluorescents in the Netherlands and Genura Electrodeless fluorescent lamps from General Electric in the United States. They both work at 2.65 MHz (ie, 2650KHz). 2400M ~ 2500MHz is a non-communication segment, microwave ovens work in this band. The current microwave source also uses this frequency. The operating frequency of electrodeless lamps at 230KHz or so is an illegal frequency band that is not recognized by international organizations. It has the same frequency interference that is extremely difficult to eliminate for equipment such as aeronautics, communications, broadcasting, and radio stations. In the future, there is a possibility that it will be banned.
2. Since the operating frequency is only one-tenth of the original, the volume of the corresponding magnetic element also increases by a factor of 10, and the coupling amount of the coupler increases from about 7 μH to about 80 μH, and it requires two. The volume of the magnetic components in the power supply is also greatly increased.
3. Although the coupler externally solves its heat dissipation problem, the coupler is completely exposed in the space, and half of the electromagnetic energy is wasted as a source of interference. The operating frequency of low-frequency electrodeless lamps has been reduced by 10 times than that of high-frequency lamps, but it is almost 10 times higher than the operating frequency of energy-saving lamp ballasts. The unobstructed freedom of radiation in space is certainly a technical retrogression.
4, users in the use of low-frequency lights, there is always a strobe feeling, according to reason more than 200 K operating frequency should not exist this problem, certainly there are some technical deficiencies.
5, the appearance of low-frequency lights is very special, manufacturing is difficult, the cost will increase, coupled with its not easy to miniaturize it is difficult to universal access to the family.
6, require special lighting and supporting: 1 special shape; 2 have a shielding function. Once the cost of a dedicated lamp doubles, the cost of the entire lamp rises and it is difficult to lower it.
7. Many large foreign lighting companies represented by OSRAM have applied for all patents of low-frequency electrodeless lamps in the world in the near future. The bloody mouth is waiting for us to enter its patent trap. Drink blood. High-frequency lights do not have patent traps.
8. Practice has proved that low-frequency lamps are more prone to stop-vibration than high-frequency lamps and that they are suddenly turned off. The more obvious the worse the environment is, the more obvious it is. This is an indisputable fact.
