PoE Market Outlook

Data from Ethernet Power Supply (PoE) market surveys and global PoE market forecasts indicate that by the end of 2022, the compound annual growth rate (CAGR) of the global PoE market is expected to grow by 13% (as shown in Figure 1), reaching $3 billion.

The most popular PoE products include switches, power injectors, IP cameras, VoIP phones, and wireless access points (APs). According to the predictions of the market research company Research And Markets, wireless APs and PoE Lighting will be the two major growth drivers in the PoE market for the next decade.

By 2025, wireless APs and PoE Lighting are expected to capture a 40% market share, dominating the PoE market. This development trend is primarily attributed to the rapid growth in demand for PoE applications in the energy, oil and gas, telecommunications, automotive, and transportation industries.

Advantages of PoE

PoE offers several advantages:

• Time and Cost Savings: The absence of dedicated power lines reduces both costs and installation time. Simultaneously, as compliance with electrical wiring regulations is not required, and certified electricians are not necessary, the installation process is simplified.

• Flexibility: Proximity to power sources is no longer a limiting factor, allowing devices to be placed anywhere that can accommodate LAN cables.

• Reliability: Centralized power sources replace low-cost wall adapters, enabling the use of a single uninterruptible power supply for system backup.

• Security: PoE provides stronger security protocols compared to wireless, enhancing protection against hacking attempts.

• Convenience: Simultaneous transmission of power and data reduces cable clutter, making the process more efficient and convenient.

PoE LED Lighting Product Introduction

Project Background

The promotion of PoE LED Lighting is based on the newly introduced IEEE 802.3bt standard, accompanied by significant improvements in traditional LED Lighting. The primary driving factor for these improvements is the ability to transmit up to 90W of power over cables up to 100m in length using four pairs of wires. This allows multiple light fixtures to be connected in a daisy chain, simplifying the installation process.

Application Scenarios

PoE can be applied in commercial buildings, sports arenas, large-scale infrastructure, and smart homes. Combining PoE with lighting introduces exciting new advantages. For example, PoE can be used to power UVC lights to combat viruses, including COVID-19.

Product Framework

By connecting PoE switches or non-PoE switches (paired with PSE power injectors) to PoE LED fixtures and other accessories, such as wireless APs and IoT sensors, a PoE Lighting system can be established. Users can control the entire LED lighting system through mobile terminals or server clouds equipped with supporting software.

The PoE lighting system comprises five basic components: gateway, user interface, PoE switch (non-PoE switch + PSE power injector), PoE node fixtures, and auxiliary devices such as sensors or switches.

Data and power reception for LED fixtures are achieved by adding a "node" inside the LED fixture housing, connected to the LED power and dimming input.
