Triac Dimming Of The Led Lamps
Posted at: Offers to Sell and Export | Posted on: Wednesday 18 July 2012 2:05 am | Poster last visit: Thursday 24 January 2013 |
Product Description:
With the process of the LED lighting market requirements and industry trends, LED by some authority directed
to the Triac dimmer areas. This is an unreasonable request, but in the process of the new electronic technology have succumbed to some old technologies linger. Some would say it is a requirement of the market, development of new technologies must go through the process. But how many people to consider the assessed whether it is worth the price of this yield?
In any case, the market or actively or passively join such an unreasonable application. The above paragraph is taken from the I love Programme network, though a bit rough, but have to admit that a little reasonable. Let us look at the various IC manufacturers have launched their own Triac Dimming program. First National Semiconductor LM3445 ON NCL3000 can be said that a good prelude to the dimming. Then is the outbreak of the type of the primary side control promotion of the program: TI sn090126, NXP SSL2101/SSL2102, Infineon, ICL8001 series of applications of electronic program. These ICs have their own advantages and disadvantages. Can be said that it is this application of the primary side control dimmer lead to a new platform, a variety of power applications in the application of this program, low-cost high-profile light effects, a very good performance. But the good times did not smooth sailing. Everyone using this application, only to find the characteristics of the LED, this load is not suitable for such a dimming. Overall, its compatibility is particularly poor, which is mainly manifested in the market a variety of kinds of dimmers and do not have a unified specification. This allows to cope with this dimmer to become stretched, obviously out of tune. Ever since a large number of electronic components, technical engineers (including myself) put into such a standard blind optimization in the development of their own LED lighting performance. In this process consumes a lot of manpower, material and financial resources, but the result was not smug. The reason is, will it adapt to the limits of a variety of applications. You bring a standard to accommodate a large number of standardization there is no standard product, ask you when is the end?
This process can be found along the dimmer LED tie a relatively good performance, but relatively cutting-edge dimmer plagued with problems. This is according to the LED lamps are generally determined by the capacitive load applications. When using trailing-edge dimmers, the abrupt drop of voltage in the cut-related off instantly, and this time because of the exigencies of the capacitive load, the larger the load capacitance continued energy, slowing the time of the voltage drop in order to maintain the normal working of the circuit; when using cutting-edge dimmer, the dimmer is turned on there will be a large turn-on voltage spikes when the capacitive load will lose the function of, so will have to not start correctly or flashes such phenomena, but if the switch to the inductive load, then, this phenomenon can be improved. (Because of the cutting-edge dimming that occurs when high pressure spike just the performance of the inductor can not change suddenly makes the stability of the output.) This cutting-edge and trailing edge of the compatibility issues. Of course, some would certainly say that using a combination of both. But so what problems will arise, with predictable results.
Originally because of the rich features of the LED colors is an excellent application of the natural dimming change. LEDs are also well suited to his dimming: PWM dimming. This is a digital control. Can also avoid a lot of restrictions, to achieve effective control. But the import market, he would face the the Triac this highway, literally the people's intention to shift with it. This is a choice of Wu Nai. Also a kind of have to pay the price choice.
Today is semiconductor suppliers generally supported the introduction of the TRIAC dimming LED drivers, in fact, not because of the dimming way exceptionally good performance, but because of consumer convenience, since many of today's Europe and the United States domestic market in the use of TRIAC dimmers on incandescent dimming, they want to directly replace incandescent bulbs with LED lamps, without the need for any transformation of the existing infrastructure, ie does not require any rewiring work.
