The LED lights need to what kind of technical difficulties
Now with the rise of the emerging industry, people the growing demand for travel at night, so there will be road lighting system. Road lighting system is the most began to appear Bai Zhi lamp, but with the continuous development of science and technology in China in the era of progress, constantly improve the living standards, people for a new improvement on the condition of the road lighting, so for the led street lamp in addition to its own advantages, and what kind of technical problems to be improved.
1, the optical design from the Angle of led street light with the light, the street lamp backlighting generally includes a light distribution, and three secondary light distribution formula, usually lights through the secondary light distribution can satisfy people the road when the brightness of the light, there are some other astigmatism uniform requirements, then no need to optical design for a third time. But neither use which kind of formula of solutions are not possible and reasonable and scientific, to some extent, there's always the optical efficiency is low, or the light too bright, some problems such as illumination is not homogeneous, then how should improve? Now some of the more mature solution is needed.
2, heat dissipation problems
the led heat dissipation problem can be directly affect the actual luminous efficiency as well as its life, as a luminous device in the daily work process of only fifteen percent to twenty-five percent of the electric energy can be turned into light energy, the rest are mostly transformed into heat energy, the longer as the light so the temperature of the led lights will gradually rise, so will lead to the efficiency of the light falling sharply.
3, driving power supply design at present for the led street lamp power supply, are almost always USES the power supply, from its structure is usually at an off-line switching power supply, because led lights work environment is very bad, so the design of the driving power supply quality of each link is very demanding. According to the current our country's current levels in the led street lamp driver power supply design should be not only attaches importance to its reliability, but also satisfies the requirement of electric shock, waterproof and other performance, the most important is security threats must be to a minimum.
the led street lamp is a new generation of green energy, for road lighting as well as the traditional street lamp has very strong advantage, although there are some problems haven't really solved, but overall is a very good one can make use of the resources, though there is a long way to go, but must hold to.
