Lighting System – Hardware Specifications
Connection Architecture
-
Each luminaire is connected to a driver, and the driver's output is directly connected to the light fixture. The master device connects to other devices through Ethernet daisy-chaining. A single driver can control up to 2 lights.
-
Recommended expansion solution: Connect a standard 24-port or 48-port Ethernet switch upstream, and then connect the switch to the gateway. This architecture supports the expansion of a large number of nodes. The gateway features one input port and one output port and supports external network connectivity. A standard 48-port switch connected to the gateway's uplink port can support up to 48 PoE central control devices.
Load Capacity
Field tests have demonstrated stable operation with 200–300 lighting fixtures. The theoretical capacity is approximately 2,000–3,000 lighting fixtures.
Power Supply Parameters
-
The central controller provides a total power output of 480W, with two types of interfaces: PoE++ ports support a maximum of 90W per port, while PoE+ ports support a maximum of 30W per port.
-
The 30W ports can connect to low-power PoE devices such as wireless APs and IP cameras. LED lighting fixtures should be connected according to their power requirements. Multiple low-power lighting fixtures can be connected in series through a single high-power driver connected to a high-power port.
-
The maximum Ethernet cable length is 100 meters. Due to voltage drop under the PoE BT protocol, the actual maximum input power available to the driver is approximately 70–73W.
Interface Configuration
-
Equipped with an RS-485 interface, allowing sensors to be connected for automated lighting control, such as turning lights on when people enter and turning them off when people leave.
-
Drivers are available in 1-channel, 2-channel, 4-channel, and 8-channel configurations. Each channel can control a single lighting fixture or multiple daisy-chained fixtures. RGBW four-color control is supported.
Product Costs and Pricing
-
The sample (demo) driver costs approximately USD 500–600. Mass-production pricing has not yet been announced and can be negotiated separately during the project implementation stage.
-
Prices for supporting components range from approximately USD 20 to USD 40+, depending on the component.
Key Product Advantages and Disadvantages
Advantages
1. Easy System Integration: Developed based on Ethernet technology, the system requires no additional protocol conversion. It can directly interface with building automation systems, including security, fire protection, ventilation, heating, and electrical systems, making multi-system integration easier.
2. High Safety: The system uses 48V low-voltage power supply. Compared with traditional AC 110V/220V solutions, it significantly reduces fire risks, making it suitable for applications with stringent fire safety requirements, such as exhibition centers, museums, and trade shows.
3. Low Long-Term Operating Costs: By integrating sensors for automatic lighting and brightness adjustment, the system achieves excellent energy efficiency. Based on cost calculations in European and North American markets, its return on investment (ROI) is better than traditional solutions over a 5–8-year period. Over an extended service life, overall costs can be reduced by 30%–50%.
4. Strong Technical Expertise: The company is reportedly the only manufacturer in mainland China specializing in PoE modules. It has completed the development of a comprehensive range of PoE products, including outdoor and industrial PoE modules, as well as PoE-to-Type-C adapters, demonstrating extensive PoE technology expertise.
Disadvantages
1. High Initial Procurement Costs: Compared with conventional waterproof power supplies and DALI systems, the hardware procurement cost is higher, making the short-term cost advantage less apparent.
2. High Maintenance and Training Costs: As this is a relatively new technology, engineers with relevant expertise are still limited in the market. Companies need to invest additional resources in technical training. Employee turnover may also result in repeated training expenses.
3. Low Market Acceptance: The current smart lighting market is relatively established. DALI systems dominate indoor lighting, while DMX and LDM systems are widely used in architectural lighting. Therefore, introducing new technologies requires substantial market education and promotion.
Industry Background
Previously participated in the development of the PoE BT standard and launched integrated PoE lighting fixtures with built-in PoE chips. Pilot projects were implemented in office buildings and schools in Mexico. However, due to high costs and insufficient market acceptance, the solution was not widely commercialized. Subsequently, the industry showed a stronger preference for separating PoE drivers from lighting fixtures.
Current mainstream smart lighting protocols:
-
DMX: A unidirectional communication protocol that has been widely used in the lighting industry for approximately 20–30 years.
-
LDM: An upgraded version of DMX, based on an RS-485 bus and supporting bidirectional communication. It also has approximately 20–30 years of application history and is one of the mainstream solutions in architectural lighting.
-
ACN: At the upper architectural lighting network level, the ACN protocol can enable TCP/IP-based communication and support fiber-optic networking. The downstream system interfaces with DMX/LDM equipment. Related devices are relatively inexpensive, have a large installed market base, and benefit from an extensive pool of experienced technical professionals.
PoE technology is currently adopted primarily in specific industries. Awareness and adoption in the consumer market remain relatively low, and the overall industry is still in the market education stage.
Background of the industry expert: The speaker is a senior lighting industry professional with 40 years of experience. He entered the industry in 1984, initially focusing on entertainment lighting before transitioning to architectural lighting. In 2010, his privately owned factory, which employed more than 1,000 people at its peak, was acquired. He was among the first generation of architectural lighting professionals in China.
