Detailed explanation of PI company's constant voltage and constant current LED driving scheme based on DALI intelligent dimming
with the progress of society and the rapid development of information technology, intelligent lighting has market advantages such as high efficiency and energy saving, simple management, diversified control and low cost, it has occupied an important position in the smart home industry. However, the technical problem that intelligent lighting is difficult to solve at present is LED Dimming. What is the most advanced dimming method at present? In the digital control signal of illumination, DALI ( Digital Addressable Lighting Interface, full name: Digital Addressable Lighting Interface) It has incomparable advantages over other lighting digital control signals, and is also the mainstream of digital control signals applied in the lighting industry at present. Therefore, DALI is praised as the latest and most advanced dimming method.
at the 28th th session (Xiamen) At the seminar on LED lighting driver and intelligent lighting technology, senior FAE Gao Zhiyuan of PI company introduced a constant voltage and constant current LED driver scheme based on DALI intelligent dimming. Gao Zhiyuan explained DALI Technology in detail from the overview to the system, so that guests can clearly and thoroughly understand the update iteration faced by DALI and LED driver IC design, and how to deal with the new challenges coming from the design of lighting power supply, and be compatible with DALI protocol in the design. He used PI's new product LYTSwitch- 6 series as an example, introduced LYTSwitch- 6 How to use semi-active PFC circuit while supporting constant voltage (CV)And constant current (CC) Control brings new choices to intelligent lighting applications.
