Sun unique limitations; fiber is too costly; market development is not enough; optical fiber can not be anti-UV and high temperature; structure is relatively complex. Limitations of solar energy is mainly reflected in the demand only collect sunlight during the day, greatly affected by climate, reaching very unstable; sunny day, the highest performance; must have a storage system for the evening and on cloudy days; energy production depends on the size of the area to collect sunlight; energy density is too low. The complexity of the constructed solar fiber optic lighting also can not enter the family of ordinary people. Solar fiber optic lighting a fatal flaw: solar energy only during the day, and used for general lighting at night, the solar fiber optic lighting is not superfluous? The answer to this question is actually to solve the solar storage solutions. I think there are three scenarios can achieve optical storage: Option One: optical storage exist emptied the external painted silver glass (mirror) ball. Option Two: light freezing for some time and then released. Option Three: solar energy into other forms of energy to be stored (such as energy, hydrogen energy, chemical energy, etc.). Start with Option One. This method is theoretically possible, but must ensure that the material is totally reflected; otherwise there will be attenuation of the energy of the light energy storage can not play role. However, this material does not exist in the real world, so this method is not feasible. Come talk Option II. Light frozen in the laboratory into a reality: According to the United States, "the Boston Globe reported, several scientists of Harvard University said recently that the experiment successfully light to stop light control in a space too After a period of time to let the light continues to spread. Their study, published in "Nature" magazine in December 2003. Unfortunately, the technology can only light pulse remains stationary with only a few percent of milliseconds, you want to practice is easier said than done, and you want to light the "frozen" live to consume a lot of energy, which more does not pay. Finally, said the program three. Option Three is the most feasible method. In my opinion, the solar energy into electrical energy is the most reasonable. Transformed into hydrogen, to solve the problem of catalyst, however, this technology now, and no big breakthrough, the energy conversion rate is too low. Current plants are solar energy converted into chemical energy, human society is yet to find the right light energy into chemical energy. Contrast energy is much more convenient, easy to use conversion rate is also relatively high.

Solar fiber optic lighting has a very broad application prospects. Fiber optic lighting market will serve as the official merchandise, occupy a considerable share of every family, and to replace the traditional incandescent thermal radiation type fundamentally, and low in saturated vapor pressure gas discharge type fluorescent lamps will also replace the current domestic market the compact fluorescent popular whole lamp.

Epochal changes on the working mechanism, sulfur lamps, which as a gas discharge of the working medium to sulfur selenium the ionization phenomena will occur under the action of a microwave RF, sulfur, to form a special structure of the intermediate mass - diatomic The sulfur molecule or dimer. At this point, it is a high energy - level state, which is unstable temporary medium in a structure, it will quickly to the lower state, to achieve recovery process, therebetween can be radiated in a broad and continuous energy , called molecular Radiation. Unlike traditional atomic radiation phenomena, it has a very Specials very concentrated, i.e., the radiant energy of the sulfur molecules, almost all converge in the visible portion of the electromagnetic spectrum; radiated a uniform like sunlight, visible light, spectral distribution uniform, in line with the human visual sensitivity curve. University sulfur lights green, sulfur lamps, mercury (Hg) is no longer required steam as the working media, choosing instead to sulfur (S), selenium (Se), to overcome the serious pollution of the environment of liquid mercury, mercury vapor, but also avoid inadvertently caused the field use of mercury hazards. The same time, the spectral distribution of the sulfur lamp uniform, reasonable composition, clutter-free ultraviolet light radiation. So that lighting ignition, no longer like the traditional light sources, such as fluorescent lamps, high pressure mercury lamp, as there is significant light pollution, and thus greatly reduces UV radiation in the environment. Protection of the human body, to optimize the work environment, clean living space. The energy saving effect is more pronounced. Up to 120 lm / W, even more than 200 lm / W, is many times higher than the traditional light source, resulting in the same lighting effect premise, a significant reduction in power consumption, light efficiency is 20 times that of incandescent, ordinary fluorescent lamps 10 times. Color performance. Longer service life, it has a long life, up to 60 000 h is 20 times that of traditional light sources. The manufacturing process is simple. So efficient sulfur lamp and fiber optic lighting, has many unique advantages, if they are together, is bound to play a greater effect. Fiber optic lighting and high efficiency sulfur lamp represents a new generation of lighting technology, and must be taken seriously enough in green engineering college sulfur lamp is carried out simultaneously with the construction of the fiber-optic network. To promote the products in the technical maturity of the market in full expansion, in order to promote the implementation of China's green lighting project, it is recommended that the fiber-optic network with high efficiency sulfur lamp as a green light source of choice in the 21st century object.
