LED lighting efficiency adjustable optical driver behind

Governments for energy requirements increasingly stringent, prompting LED dimming body (LED) lighting needs warming, to achieve efficient dimming and solve the flicker problem, TI released before the two phase of highly integrated light adjustable AC to DC (AC-DC) LED lighting driver, can fully meet the modified light bulb (Retrofit Bulb), LED (Ballast), light stabilizer (Downlight) and light (Spot Light) dimming requirements of lamps.

TI (TI) Asia analog product market development power application products Senior Application Engineer Xiao Yizhou said that although the traditional bulbs can also be light, but more power and short service life, leading to the traditional adjustable light bulbs must be regularly maintained. The LED lamp into the adjustable light power supply driver IC, both advantages not only LED than the traditional light bulbs 80%, service life of at least twenty thousand hours, can adjust light, improve energy efficiency, accelerate energy-saving LED lighting to replace traditional lighting.

As the flag of energy-saving LED lighting market, TI has launched the TPS92070/LM3448 series of adjustable optical scheme, the upper bound of current high precision characteristics can be defined accurately for current customers, eliminating the customer does not stop the correction time and cost, and because of its high performance structure, can reduce the driving support around IC parts. To further reduce the cost of customers.

Xiao Yizhou further pointed out that the current TI a series of adjustable light driven IC are mainly exported to Japan, Europe and the United States and other countries, and also day standard different, IC driver required specifications are not the same. For example, TPS92070 because of its structural design for the isolation type, high safety, can meet the safety requirements of the United States; Japan is the main shipping isolation design of LM3448, and has no effect on LED isolation design, the whole lamp cost is about 2%, all depends on customer needs and.

Xiao Yizhou said, in the relevant energy-saving regulations, Japan, Europe and other developed countries have been widely used with imported adjustable LED lamp light driven IC, while developing countries such as Chinese, because there is no requirement, the relevant laws and regulations, the use of the free LED lamp dimming function with low cost. As for Taiwan, there is no relevant regulations, but the existing lighting manufacturers import dimming driver IC, its application market still mostly for entertainment lighting market, indoor lighting, outdoor lighting and emergency lighting are not spread, if the future energy-saving regulations made further, believe that energy-saving LED lighting will be more prevalent.
