Smart lighting is not a new concept. The current LED industry has entered a low-cost era. Looking for a new development direction is a big trend. Smart lighting is one of the most important areas with great market potential. In 2014, the global smart lighting market was about 1.544 billion US dollars. In 2015, due to the global economic downturn, the growth rate was lower than expected. However, with the development of industry technology and the positive promotion of manufacturers, it will continue to grow. It is expected that in 2019. The market size can reach 14.353 billion US dollars. Philips official data estimates that the global lighting market revenue will reach 90 billion euros in 2020, of which up to 57.4% of revenue from LED lighting and control systems. The intelligent lighting control system can automatically collect various information in the lighting system according to environmental changes, objective requirements and user requirements, and perform corresponding feedback control of working state information to achieve the desired control effect. However, if the intelligent control system controls different lighting fixtures, it needs to be based on a communication protocol between the devices. At present, due to different development backgrounds and functional characteristics, there are many intelligent lighting communication protocols on the market. The main foreign applications for intelligent lighting control systems are:

First, the DALI protocol

DALI, as part of the IEC929 standard, provides communication rules for lighting equipment. It came out in the mid-1990s, and commercial applications began in 1998. In Europe, DALI has been accepted as a new standard by ballast manufacturers. When formulating standards, the DALI protocol clearly defines not the development of the most functional and complex building control system, but the establishment of a well-structured ballast-specific lighting system. Therefore, DALI's specialty is not used to build complex bus systems, but for indoor intelligent lighting control.

The DALI protocol is an asynchronous serial communication protocol. The digital signal is compiled by Manchester. Compared with the traditional analog technology controlled dimming, the DALI-based digital control dimming technology features:

1, dimming is addressable, bringing a lot of flexibility to control

2, dimming anti-interference ability, wide range of dimming

3, dimming installation is simple, dimming power supply can quickly install wiring.

Second, the EIB agreement

The EIB protocol is a control-oriented network communication protocol. The purpose of communication is to realize the interaction between the sensor and the actuator, starting with the exchange of the defined data structure and ending with the functional application. Its European-based building automation (BA) and home automation (HA) standards have been adopted by the Consumer Electronics Manufacturers Association (CENA) as the home network EIA-776 standard.

It is used in all branches of the home building sector such as lighting, security, HVAC, and time event management. It is characterized by distribution, interoperability, flexibility and openness. Recent developments have shown that the EIB protocol is increasingly being applied to intelligent lighting systems.

Third, the KNX protocol

In May 1999, the three major bus protocols EIB, BatiBus and EHSA in Europe merged to form the Konnex Association and proposed the KNX protocol. The KNX protocol is based on EIB, taking into account the physical layer specifications of BatiBus and EHS, and absorbing the advantages of BatiBus and EHS distribution modes, providing a complete solution for home and building automation.

The KNX-based system can connect all the components through a bus, each component can work independently, and at the same time, it can be centrally monitored and controlled by the central control computer. The components programmed by the computer can perform tasks such as switching, control, monitoring, etc. independently, and can be combined according to requirements, so that the function can be flexibly changed without increasing the number of components.

Fourth, C-Bus agreement

The C-Bus Lighting Management System is an intelligent, programmable lighting management system developed by Gerard Industries Dty Ltd in Australia in the early 1990s. Each component in the system has a built-in microprocessor to transmit, identify and memorize information in the form of data signals, and through a pair of unshielded twisted pair (UTP) as a bus architecture, the units of the system can work together to each other. External lighting and other facilities are controlled.

C-Bus is a two-wire lighting system that uses five types of cables to connect all components into a network. Various complex functions are set by software. The protocol on the system bus is CSMA/CD, and each network segment can be connected to 100 units. The network segments can be flexibly connected. For example, network bridges, hubs, and switches are used. The number of network segments is not limited. It adopts a free topology and can be designed into a topological structure such as a line, a tree or a star. The networking is very convenient.

Power Transformer

The application of the transformers we produce:
1. Building Automation and Control Systems
In modern buildings, power transformers are used to supply power to building automation systems, including lighting control, HVAC (heating, ventilation, and air conditioning) systems, and security systems.
They convert the main power supply to a safe and manageable voltage level, ensuring optimal performance and reliability of these systems.
2. Industrial Control Panels and PLCs (Programmable Logic Controllers)
Industrial control panels and PLCs require precise and stable power supplies to function correctly. power transformers provide clean, filtered power to these devices, minimizing interference and ensuring accurate control.
3. Machine Tool and Automation Equipment
In manufacturing and production facilities, power transformers are used to power machine tools, automation equipment, and robotic systems.
They ensure that these devices operate at the correct voltage level, preventing damage and maximizing productivity.
4. Low-Voltage Electrical Distribution
power transformers are essential components in low-voltage electrical distribution systems, where they convert the main power supply to the required voltage level for distribution to various loads.
This includes supplying power to outlets, lighting fixtures, and other electrical devices in commercial and residential buildings.
5. Audio-Visual and Entertainment Systems
Audio-visual and entertainment systems, such as sound systems, stage lighting, and projection equipment, often require power supplies.
power transformers provide clean, stable power to these systems, ensuring optimal performance and minimizing interference.
6. Medical Equipment and Laboratories
Medical equipment and laboratories require precise and reliable power supplies to ensure accurate measurements and safe operation.
power transformers are used to supply power to various medical devices, laboratory instruments, and testing equipment.
7. Renewable Energy Systems
In renewable energy systems, such as solar and wind power plants, power transformers are used in energy conversion and distribution processes.
They help in stepping down the generated voltage to a level suitable for distribution to the grid or for use in local loads.
8. Backup Power Systems
Backup power systems, including uninterruptible power supplies (UPS) and emergency generators, often incorporate power transformers.
These transformers ensure that the backup power supply is delivered at the correct voltage level, maintaining power continuity during power outages.
In summary, power transformers are vital components in numerous applications where safe, reliable, and efficient power distribution is essential. Their ability to convert and distribute electrical energy at low voltages makes them ideal for use in building automation, industrial control, machine tools, low-voltage electrical distribution, audio-visual systems, medical equipment, renewable energy systems, and backup power solutions.
