Non-isolated circuit programs and security of the race debate in recent years, LED lighting circuit program. In fact, since the incandescent invention and access to thousands of families to illuminate the centuries, although the authentic non-isolated solutions, but has been relatively safe, in the light of the incandescent hand to dabbling it, unless the electrical master. Program of non-isolated circuit lighting products account for a large market share. LEDs present application circuit is non-isolation circuit program, but its application circuit is simple, small-footprint, lower production costs, should be into the millions of households lighting mass market popularity of a new generation of solar LED street light.
For the current HV LEDs simple application circuit, the need for supporting high-voltage constant-current source driver IC? Order in accordance with the principle of LED constant current source needs to work reliably, should arouse the concern of our LED lighting engineers and IC design manufacturers, solar LED street light, after all, is a huge market of world-class. Opinion is very necessary to develop a number of the HV LEDs for the high-voltage constant-current driver ICs, in order to improve the current precision and stability of the HVLEDs application circuit, reliability, worthy of the IC design companies to innovative design to create a new generation of power IC products.
The HV LEDs due to the application of technology, system circuit Heng less peripheral components, suitable for home lighting require low-cost mass market is likely to dominate the future of general lighting market; LV led high bay lights can be in light color, brightness, etc. for a variety of techniques design and adjustment, applicable to commercial lighting market, such as shopping malls, hotels, guesthouses and other public commercial establishments.
