LED lighting after the potential good, also in the field of LED chip industry put a lot of effort, but it is still an important role to drive the LED light source circuit design, circuit design, even if the chip and package, no matter how poor is futile, general view, the circuit design of the led emergency lighting is still not off the volume, the cost of a few basic focus, but one of the PFC is also an important reference index.
From the overall LED lighting system to observe the LED chip and packaging sectors accounted for a very high proportion of the overall cost, circuit design, however, although the proportion is not high, but after all, the relationship between the demands of energy-saving and carbon, how to reduce the power consumption power consumption become system operators have to think about the subject, but on the other hand, LED lighting is also facing costs, life expectancy and volume design requirements, while facing many requirements, system operators will also be pressure onto semiconductor industry, the semiconductor industry is also facing some challenges in the provision of solutions. Linzhi Yan, technical marketing manager of ON Semiconductor operation of the consumer products business group, pointed out on his own observation, the lighting industry for circuit design is quite strange, this type of problem, usually by the semiconductor industry to find ways to solve, and lighting Owners can spend more effort to achieve a multiplier effect on the institutions, optical, thermal and exterior design.
Due to the lighting industry for circuit design is quite strange, but in order to meet the requirements of the appearance or institutional design, the semiconductor industry must stand with the angle as much as possible to help customers solve all problems, plus they need to quickly ramp, in the development board the design, but also, as far as possible toward the can "immediate shipment" as the goal, as far as possible in the shortest possible time to enter the shipping process.
Apply different circuit design concepts also slightly different
LED lighting applications can be broadly divided into indoor and outdoor car lighting and other types, although these three types of areas can still be broken down quite a lot of categories, is always, however, the circuit design is not much different, has a more Most of the differences, operating temperature, system size, reliability and cost factors. For example, indoor lighting applications, such as residential or commercial areas, they will pay more attention to the problems of cost and system size, For outdoor emergency lighting inverter, might not need to consider the cost, but the operating temperature and reliability will be relatively more important. As for the car lighting, although without the help of the AC-DC components, but after all, and the personal safety of a high degree of association will be extra requirements in terms of reliability and life.
Indoor and outdoor different requirements
Outdoor lighting and indoor compared to its harsh operating environment, the supplier industry level drop, and outdoor lighting at this stage no one is more clear standards expected future outdoor lighting market to grow further still take a while time. But aside talk about the external environment, in fact, the higher power requirements of outdoor lighting, the main reason is that the LED lights are more series, the power will also increase, in parallel, will face The turn-on voltage, therefore, to the development to the outdoor lighting, the solution must be relatively complete, in order to meet the design requirements.
