Light plays a crucial role in our daily lives, whether at home, in the office, or on the road. Without adequate lighting, performing routine tasks would be nearly impossible. It's no surprise, then, that lighting consumes a significant portion of global electricity. According to the U.S. Energy Information Administration, in 2016, residential and commercial/industrial lighting in the U.S. used about 279 billion kilowatt-hours of electricity. This accounted for roughly 10% of total energy use in these sectors and around 7% of the country’s overall energy consumption. Similar figures are seen in other developed nations.
Traditional lighting technologies, like incandescent bulbs, are notoriously inefficient. These old bulbs convert less than 5% of the energy they consume into visible light, with the rest being wasted as heat. However, this outdated technology is gradually being replaced, especially with the rise of LED lighting. LEDs can now achieve over 50% energy efficiency, making them a far more sustainable option. As LED prices have dropped and incentives for energy-efficient solutions have grown, adoption rates have skyrocketed. Some projections suggest that widespread LED use could reduce electricity consumption by up to 40% by 2030.
Beyond their energy efficiency, LEDs also enable smart lighting systems. These systems are becoming increasingly popular because they offer greater energy savings and can be tailored to meet specific needs. Smart lighting not only enhances user experience but also supports more sustainable practices.
Smart lighting, however, relies on advanced semiconductor components. For applications ranging from 10W to 100W in offices, factories, and homes, ON Semiconductor’s FL7740 (primary side) and FL7760 (DC-DC buck) work together to simplify design and reduce component count. They deliver precise constant voltage regulation and support both analog and PWM dimming. These features help engineers meet and exceed evolving global standards.
The FL7740 also offers fast response times, low power consumption—even in standby mode—which is essential for smart lighting systems. It provides a high power factor of approximately 0.9 and less than 10% total harmonic distortion (THD), along with universal input capabilities at half load.
Dimming is an important feature in modern lighting. The FL7760 supports a wide analog dimming range of 5 to 100%, making it a practical choice for lighting designers. It also handles PWM dimming across the entire range, addressing common issues like flicker and noise. A key innovation of the FL7760 is its ability to seamlessly switch between analog and PWM dimming when levels drop below 5%, ensuring smooth performance even at very low brightness.
Thanks to advancements in semiconductor technology, smart LED lighting has become more practical and easier to implement. This not only improves working and living environments but also helps save billions of kilowatt-hours of electricity in the near future.
AD8 Floating Solar Cable
AD8 standard floating Solar Cable is a kind of equipment used for floating photovoltaic power generation. It consists of photovoltaic cells that convert solar energy into electricity. The device is designed to float on the water, while it can be fixed to the water by a buoy and anchorage device to prevent drifting.
AD8 standard floating solar cable has the following characteristics:
1. Efficient use of solar energy: photovoltaic cells can convert solar energy into electricity to achieve efficient power generation.
2. Environmentally friendly: photovoltaic power generation does not produce pollutants and greenhouse gases and is environmentally friendly.
3. Save land resources: Floating solar cable can use the space on the water surface, saving the use of land resources.
4. Strong wind and wave resistance: floating solar cable adopts stable design, has strong wind and wave resistance, and can operate normally in bad weather conditions.
5. Easy installation and maintenance: Floating optical cables are relatively simple to install and maintain, and can be quickly deployed and adjusted.
AD8 standard floating solar cable is suitable for a variety of water environment, such as lakes, reservoirs, rivers, etc. It can be used in power stations, farmland irrigation, drinking water treatment and other fields to provide local clean energy and power supply.
