New requirements of intelligent lighting for LED driver (two) (IC)

Digital dimming technology into a new battlefield

Intelligent lighting not only affects the LED driver architecture changes, but also will promote the new circuit layout and dimming (Dimming) technology has emerged, in order to achieve a more convenient, lower cost digital control solutions. Insiders expect the next 1 to 2 years will be a critical period of LED lighting to digital dimming, the relevant LED driver chip and system solutions are expected to be a large number of baked, the supply chain industry has become a new technology battlefield.

It is understood that the digital lighting controller products series will solve many common problems faced by LED lighting, such as low frequency 100Hz/120Hz and quality of light flashing, dimmer compatibility, line voltage and current accuracy of different load conditions, and different LED file etc.. Flexible choice of different control schemes, parameters and protocols can further improve energy efficiency. This allows artificial light to be compatible with environmental changes from dawn to night, from spring to winter. So that people can make use of smart phones and tablet PCs and other mobile terminals, arbitrary control of LED brightness and color temperature, by changing the color to create a different atmosphere. In addition, the bright lights in the night to bring a sense of security.

Mr Edward Chang also said: "intelligent lighting is part of a wave of things and cloud computing, network security should become one of the most important issues, OPTIGA safe controller is to ensure network security experts.

LED drivers are moving toward cost driven areas

With the LED source power is rising, the end product prices continued to decline, and the proportion of IC accounted for LED driving overall lighting cost more prominent, chip makers have increased development of higher integration of the linear driving scheme, to meet the system manufacturers reduced bill of material (BOM) into the demand. "On the one hand, LED drives are moving in a more intelligent direction; on the other hand, LED drives are moving towards cost - driven applications, such as the replacement market. "Mr Edward Chang spoke to reporters.

Mr Edward Chang indicates that costs may come from different aspects. For example, LED products are increasingly concerned with the protection of surge voltage. Customers can decide whether or not they are willing to spend money on surge protection devices or power supplies that have both surge protective devices and added value, or spend more on reliability.
