Discussion on design trend of LED lighting circuit

Slightly different application circuit design concept application difference of LED lighting can be divided into indoor and outdoor lighting and vehicle types, although these three areas still quite a lot of subdivision categories, but the total return, difference circuit design is not much, with differences, mostly in the operation temperature system, volume, reliability and cost etc.. For example, indoor lighting applications, such as home or commercial areas, will pay more attention to the cost and volume of the system, if the outdoor.

Although optimistic about the potential of LED lighting industry, also put a lot of effort in the field of LED chip, but the circuit design, it is still an important role in driving the LED light source, even if the chip and package as well, circuit design is poor in vain, in general, the circuit design of LED lighting is still off the volume and the cost a few basic point, but is also an important reference index of PFC.

Discussion on design trend of LED lighting circuit

From the LED lighting system to the overall observation, LED chip and packaging industry accounted for the overall cost quite high proportion, but the circuit design although the proportion is not high, but after all is the pursuit of such carbon, how to reduce the power of a system industry must consider the subject in power, but on the other hand, LED lighting is also facing to cost, service life and volume etc. the design requirements, at the same time facing many requirements, system operators will also pressure onto the semiconductor industry, also let the semiconductor industry in providing solutions also face some challenges. Slightly different application circuit design concept application difference of LED lighting can be divided into indoor and outdoor lighting and vehicle types, although these three areas still quite a lot of subdivision categories, but the total return, difference circuit design is not much, with differences, mostly in the operation temperature system, volume, reliability and cost etc..

For example, indoor lighting applications, such as household or commercial areas will be more attention to cost and volume of the system, if the outdoor lighting, may need to take into account the cost, but the operation temperature and reliability will be relatively more important. As for the use of automotive lighting, although without the help of AC-DC components, but after all, with a high degree of personal safety, reliability and life expectancy will be particularly demanding.

Indoor and outdoor requirements are different

Compared with indoor outdoor lighting, the working environment is strict, the level of industry supply gap is large, and at this stage of the outdoor lighting also has a clear standard, expected future outdoor lighting market to further grow, still need a period of time. But left away in the environment not to talk, in fact, outdoor lighting power demand is high, the main reason is that the LED lamp series, more power will increase, if carried out in parallel, will also face the problem of the turn-on voltage, so if we want to solve the development of outdoor lighting. Plan must be relatively complete, can meet the design requirements. Indoor and outdoor lighting will need to convert AC-DC components, AC and DC, but still need the assistance of DC-DC to light the LED light source, although the two components are very important, but the former high voltage must be carrying 110V or 220V, it is not easy to enter the threshold, the entry threshold is low, competition is more fierce.
