The lighting system is crucial in many places, especially in emergency situations such as fires, earthquakes, or other evacuation scenarios. Therefore, lighting systems need a backup power source to ensure that lighting equipment continues to operate even when the main power source fails. This is where the “lighting inverter” comes into play. A “lighting inverter” is a device used in lighting systems, typically employed to address power outages or electrical failures. It is defined as a type of power inverter or Uninterruptible Power Supply (UPS) used to supply power to emergency lighting fixtures, ensuring that lighting equipment within a building or facility continues to function in the event of a grid power failure.
A lighting inverter converts direct current power (typically from batteries) into alternating current power to supply lighting fixtures and other equipment related to the lighting system. When the main power source fails, the lighting system automatically switches to the backup power provided by the lighting inverter, ensuring a continuous power supply to the lighting equipment for necessary illumination during emergency evacuations and safety measures. Such devices are commonly used in various locations, including commercial buildings, hospitals, schools, sports arenas, subways, tunnels, and more. With the continuous increase in global demands for energy efficiency and environmental sustainability, the Lighting Inverter market is poised for significant and sustainable growth.
From the perspective of output waveform types, Lighting Inverters can primarily be categorized into the following types:
1. Pure Sine Wave Inverter: Pure sine wave inverters produce an output waveform that is identical to the pure sine wave AC waveform provided by the electrical grid. The output current from this type of inverter is very stable and smooth, making it suitable for devices that require high-quality waveforms, such as lighting equipment and electronic devices. Pure sine wave inverters can be compatible with nearly all types of loads and provide high-quality electrical power.
2. Modified Sine Wave Inverter: Modified sine wave inverters produce an output waveform that is an approximation of a sine wave but differs from a pure sine wave. While it can meet the needs of general applications, it may cause interference or noise for certain sensitive loads, such as some power tools, electronic devices, and precision instruments.
3. Square Wave Inverter: Square wave inverters produce an output waveform that is similar to a square wave. These inverters are typically low-cost but have poor waveform quality and are unsuitable for many loads. Square wave inverters are mainly used for simple resistive loads and are not suitable for lighting equipment and other sensitive devices.
It’s worth noting that for lighting systems, pure sine wave inverters are the ideal choice because they can provide high-quality power output, avoiding interference and noise, and are also compatible with various types of lighting equipment. Modified sine wave inverters and square wave inverters may have adverse effects on certain lighting equipment, so the choice of inverter should be based on the specific requirements and types of loads.
Phenix Lighting as a specialized company with over 20 years of expertise in emergency lighting solutions, not only offers a comprehensive LED Emergency Driver series but also leads the industry in Emergency Lighting Inverter technology. Phenix Lighting’s Lighting Inverter products belong to the category of pure sine wave inverters, known for their flexibility in accommodating various types of lighting loads. Additionally, these products feature slim size, lightweight design, and robust functionality. Currently, the company primarily focuses on Mini Lighting Inverters and Parallelable Modular Inverter ranging from 10 to 2000W.
Phenix Lighting possesses proprietary patented technology for 0-10V Automatic Preset Dimming (0-10V APD). When there is a power outage, the inverter will automatically reduce the power output of dimmable fixtures, ensuring that their brightness meets emergency lighting requirements. This effectively extends the runtime of the emergency lighting system or increases the number of fixtures on the load, helping customers save costs and achieve energy efficiency goals. Phenix Lighting’s 0-10V APD technology contributes to sustainable lighting solutions by reducing energy consumption and carbon footprint, contributing to the development of more environmentally friendly lighting systems.
