LED lighting, after the potential optimistic about the industry, is also the field of LED chips to put a lot of effort, but the circuit design, it is still an important role in driving LED street light source, even if the chip and package, no matter how poor, circuit design is also futile, summed up the view, the circuit design of the LED lighting is still not off the volume, the cost of a few basic focus, but one of the PFC is also an important reference. what is the best led grow light?
To observe the overall LED lighting systems, LED chip and packaging areas accounted for a very high proportion of the overall cost, however, circuit design, although the proportion is not high, but that is the relationship between the demands of energy-saving and carbon, how to reduce its power consumption system operators must consider the subject of power has become, but on the other hand, LED lighting is also facing the cost of life and volume design requirements, while facing the many requirements, system operators will also be pressure onto semiconductor industry, the semiconductor industry is also facing some challenges in the solution provider.
Lighting industry for circuit design is quite strange, but with the appearance or institutional design requirements, the semiconductor industry must stand with the point of view as much as possible to help customers to solve all problems, coupled with the need of rapid mass production in the development of the circuit board design.
LED lighting applications can be broadly divided into indoor and outdoor lighting and other car types, although these three areas can still be broken down quite a lot of categories, but always look at the circuit design is not much difference, compared withdifferences, mostly in the operating temperature, system size, reliability and cost factors. what is the best led grow lights? For example, indoor lighting applications, such as home or commercial areas will be more attention to cost and system size, if the outdoor lighting may be less need to take into account the cost, but the operating temperature and reliability, the relative more important. As for the car lighting, although no AC-DC component description, but, after all, have a high degree of personal safety, reliability and life will be extra requirements.
Outdoor lighting and indoor compared to its more demanding operating environment, the supplier industry standards gap at this stage of outdoor lighting is no more clear standards expected future outdoor lighting market to grow further still take some time. The external environment but put aside to talk about, in fact, the higher the power needs of the outdoor lighting, its main reason is that the LED lights more power will also increase in series and parallel, will face turn-on voltage, so to to outdoor lighting, and its solution must be relatively complete in order to meet the design requirements.
Indoor and outdoor lighting will need the AC-DC components to the conversion of AC and DC, what is the best led grow light but still need the assistance of the DC-DC LED light source to illuminate the two types of components are very important, but the former must carry the high voltage of 110V or 220V barriers to entry is more difficult, and the latter low barriers to entry, competition is more intense.
In the larger LED lighting apparatus, such as street lighting, and its power is generally more than 50W, the isolation design will most likely be a front-end and back-end level two power architectures. The front end will provide power factor correction, and the back-end level isolation and regulation will provide current to drive the LED load.
